    Opis:
    The Polish Universal Neonatal Hearing Screening Program (PUNHSP) has been carried out in Poland for 14 years. The main aim of this Program is to organize hearing screening tests and to gather the Informations about risk factors of hearing loss in almost all newborns in Poland. It consists of 496 centers at 3 referral levels. A total of 5 458 114 children had been registered in the Central Database (CDB) of PUNHSP by the 22nd of August 2017. Bilateral sensorineural hearing loss was the most frequently appearing hearing impairment in children. It was diagnosed in 260 cases in 2016. This report presents the most important results and conclusions concerning the running of the PUNHSP in 2016.

    Opis:
    The aim of this study was to evaluate the hearing status of call centre operators in relation to their noise exposure. Conventional pure-tone audiometry and extended high-frequency audiometry were performed in 49 workers, aged 22-47 years (mean ± SD: 32.0 ± 6.0 years), working in call centre from 1.0 to 16.5 years (mean ± SD: 4.7 ± 2.9 years). Questionnaire inquiry aimed at collecting personal data, the information on communication headset usage habits, self-assessment of hearing ability and identification of risk factors for noise-induced hearing loss were also carried out. Sound pressure levels generated by the communication headset were determined using the artificial ear technique specified in CSA Z107.56-13 (2013) standard. The background noise prevailing in offices was also measured according to PN-N-01307 (1994) and PN-EN ISO 9612 (2011). Personal daily noise exposure levels in call centre operators varied from 66 to 86 dB (10-90th percentile). About half of the study subjects had normal hearing in the standard frequencies (from 250 to 8000 Hz) in both ears, while only 27.1% in the extended high-frequencies (9-16 kHz). Moreover, both high-frequency and speech-frequency hearing losses were observed in less than 10% of audiograms, while the extended high-frequency threshold shift was noted in 37.1% of analysed ears. The hearing threshold levels of call centre operators in the frequency of 0.25-11.2 kHz were higher (worse) than the expected median values for equivalent (due to age and gender) highly screened population specified in ISO 7029 (2017). Furthermore, they were also higher than predicted for 500-4000 Hz according to ISO 1999 (2013) based on the results of noise exposure evaluation.

    Background. A stapedectomy or stapedotomy is known as the best treatment option for patients with otosclerosis. Otosclerosis is a primary disease of the bony labyrinth capsule, which is characterized by one or more localized foci, where bone deposition occurs repeatedly. The best and most effective treatment option is a stapedectomy or stapedotomy. Objectives. The present study evaluated the short-term hearing results in patients with otosclerosis after primary stapes surgery. Material and methods. In this retrospective study, the short-term hearing results of all patients with otosclerosis after a primary stapedotomy admitted to the Ahvaz Emam hospital from 2007 to 2017 was evaluated. Improvement in hearing was evaluated according to the pre- and post-audiometry results. Air Conduction (AC), Bone Conduction (BC) and Air-Bone Gap (ABG) thresholds were recorded at 500, 1 000, 2 000 and 4 000 Hz. SPSS software (Version 22.0) was used for statistical analysis. Results. Of the 413 cases, 231 (55.93%) and 182 (44.07%) were females and males, respectively. The mean age of patients was 39.06 ± 11.29 years. The disease in 131 (31.72%) was bilateral. The mean ABG in 341 patients (82.63%) ≤ 10 dB and in 52 patients (12.47%) was 10–20 dB. Conclusions. The results of the study showed that a primary stapedotomy is a successful and effective way to improve short-term hearing results in adults with otosclerosis.

    Opis:
    Introduction: Evidence regarding the effect of speechreading is lacking in age-related hearing loss (presbycusis). Thus, in individuals with presbycusis, this study determined whether speechreading would improve word intelligibility. Moreover, the study investigated the effect of speechreading on word intelligibility depending on hearing impairment severity. Materials and methods: This analytical, cross-sectional study involved two groups of individuals aged > 65 years that were enrolled by convenience sampling: 29 individuals with bilateral sensorineural hearing loss compatible with presbycusis (n=58 ears; mean age, 74.1±9.4 years) and 10 controls with at-most-mild hearing loss (n=58 ears; mean age, 73.8±8.5 years). All participants underwent a comprehensive medical and audiological evaluation, which included speech audiometry with and without observation of the audiologist’s face, i.e. speechreading. Within each group, the effect of speechreading was determined as a change in the speech reception threshold. For all statistical analyses, p < 0.05 was considered significant. Results: Both in individuals with presbycusis and controls, speechreading significantly improved speech discrimination (p<.001<.05); however, compared to controls, this effect of speechreading on speech discrimination was more pronounced in individuals with presbycusis (p<.001). Discussion: Individuals with presbycusis or hearing impairment displayed improved spoken-word intelligibility when spoken-word recognition was coupled with speechreading. Thus, speechreading may serve as a “third ear”.

    Objective: In this study, our aim was to investigate whether Monocyte/HDL ratio is a marker of the prognosis of the idiopathic sudden hearing loss (ISHL). Study design: Retrospective, case-control clinical trial. Materials and Methods: 45 patients, who were diagnosed with idiopathic sudden hearing loss and were treated with the same therapy regime and 47 healthy volunteers, who applied to the hospital for routine controls and had audiological and laboratory examination between March 2014 and December 2015, were included in the study. Monocyte/HDL ratios of the patients in the study and control groups were calculated from the results of the blood counts and biochemical analysis. Additionally, the study group was divided into two sub-groups regarding their responses (responders and non-responders) to the treatment determined by the audiological examination, which was carried out after 3 months according to the Siegel criteria. The Monocyte/HDL ratios between the groups were statistically evaluated. Results: There was no statistically significant difference between the MHRs of the study and control groups (p=0.574). However, the MHR was significantly higher in the non-responders’ group compared with the responders’ group, although they were treated with the same therapy regimen (p=0.005). Conclusion: There was no difference in MHRs between study and control groups. However, as MHR was higher in the patients with good prognosis compared with the patients with bad prognosis, we believe that regarding the ISHL, MHR is not a predictive value but might have prognostic marker.

    Introduction and objective. Work noise exposure among farmers can cause hearing loss. Farmers are exposed to hazardous noise from equipment and domestic animals, and experience high rates of noise-induced hearing loss. The aim of our study was to evaluate the hearing thresholds of farmers in Korea. This study is the first to evaluate hearing impairment in Korean farmers nationwide. There have been few studies that have performed audiometric testing to measure hearing impairment at the national level in Korea. Materials and method. Through the Farm Work Safety Model Project among the 40 villages in which inhabitants received health check-ups from 2006–2008, 2,027 people from 35 villages were targeted (957 people in 16 villages in 2006, 436 people in five villages in 2007, and 634 people in 14 villages in 2008) and underwent pure tone audiometry tests. 2,027 people from 35 villages underwent pure tone audiometry tests through the Farm Work Safety Model Project. The tests were conducted using a portable audiometer, and air conduction thresholds were determined. Results. Hearing impairment at 3kHz and above was more prevalent in men than in women. The prevalence of moderate- to-profound hearing impairment was 19.6% in the total study population and increased with age. Conclusions. It is proposed that the high prevalence rate of farmers’ hearing impairment may be due to excessive workplace noise. To manage farmers’ hearing health, precise evaluations of farmers’ hearing acuity and noise exposure on farms should be conducted. This study might be a stepping-stone to protect farmers’ hearing health.

    Opis:
    Introduction. Lyme borreliosis (LB) is endemic spirochetosis with a transmission mechanism, which is often marked by a durable, recurrent course with multiple organ damages. LB is characterized by the appearance of migrating erythema at the site of tick bite. Durable persistence of the agent promotes disease progressing and occurrence of serious complications related to the nervous system, the heart and the locomotive apparatus. Among infrequent and especially dangerous complications of LB is damage to the hearing apparatus with the development of sensorineural deafness – hearing loss, which develops within 24 hours due to function impairment of the internal ear or auditory nerve. That infectious diseases account for 12.8-13% of numerous causes of sensorineural deafness development. Most frequently, the disease caused by B. burgdorferi is mentioned. Aim. To analyze the clinical case of Lyme borreliosis complicated by the sensorineural hearing loss. Materials and methods. The analysis of clinical-laboratory and instrumental data of the patient with Lyme borreliosis, whose course of the disease was complicated by sensorineural hearing loss. The patient received care at Lviv Regional Infectious Diseases Clinical Hospital (LRIDCH). Results. The article presents a clinical case of Lyme borreliosis, complicated by sensorineural hearing loss, which appeared on the 15th day from the onset of erythema annulare in the patient. Hearing recovery in the patient could not be achieved via administration of etiotropic treatment (2.0 g/per day of ceftriaxone for 28 days), which was likely associated with late visit of the patient for medical aid. Conclusions. Sensorineural hearing loss is one of the rare, but severe lesions of auditory analyzer in LB. Hearing improvement after antibiotic therapy is possible in certain cases in early treatment.

    Opis:
    Introduction: Surgical treatment of deafness by cochlear implants is used for more than 40 years, and during this period permanently, gradual and significant expansion of indications for this surgery has been observed. Material and methods: In our Department in the years 1994-2018 1480 cochlear implantations were performed, both in adults (647) and in children (883). In this study current indications and the rules for eligibility of patients based on 25 years of experience are presented. Results: Indications for cochlear implantation in adults are: 1) bilateral postlingual deafness, 2) bilateral sensorineural hearing loss - in pure tone audiometry > 70 dB HL (average 500-4000 Hz) and in speech audiometry in hearing aids understanding < 50% of words for the intensity of the stimulus 65 dB, in the absence of the benefits of hearing aids, 3) bilateral profound hearing loss for high frequency with good hearing for low frequency, in the absence of the benefits of hearing aids, 4) some cases of asymmetric hearing loss with intensive tinnitus in the deaf ear. An indication in children is bilateral sensorineural hearing loss > 80dB HL confirmed by hearing tests, after about 6 months of rehabilitation with the use of hearing aids. Discussion: Although cochlear implantation is used for more than 40 years, the indications for this treatment underlies constant modifications. They concern the age of eligible patients, implantation in patients with partially preserved hearing, as well as treatment for patients with difficult anatomical conditions. In many countries, bilateral implantations are commonly performed, and more and more centers recommend this treatment in the case of unilateral deafness or asymmetric hearing loss, especially with the accompanying tinnitus in the deaf ear.

    Opis:
    The article shows 2 cases of unusual presentation of acute acoustic trauma and blast injury due to occupational exposure. In the case of both patients the range of impaired frequencies in pure tone audiograms was atypical for this kind of causative factor. Both patients had symmetrical hearing before the accident (which was confirmed by provided results of hearing controls during their employment). A history of noise/blast exposure, the onset of symptoms directly after harmful exposure, symmetrical hearing before the trauma documented with audiograms, directed initial diagnosis towards acoustic/blast trauma, however, of atypical course. Acute acoustic and blast trauma and coexisting acoustic neuroma (AN) contributed to, and mutually modified, the course of sudden hearing loss. In the literature there are some reports pointing to a higher sensitivity to acoustic trauma in the case of patients with AN and, on the other hand, indicating noise as one of the causative factors in AN.

    The aim of the study was to evaluate the combined effect of noise exposure and additional risk factors on permanent hearing threshold shift. Three additional risk factors were: exposure to organic solvents, smoking and elevated blood pressure. The data on exposure and health status of employees were collected in 24 factories. The study group comprised of 3741 noise male exposed workers of: mean age 39§8 years, mean tenure 16§7 years and LEX;8h = 86 § 5 dB. For each subject, hearing level was measured with pure tone audiometry, blood pressure and noise exposure were assessed from the records of local occupational health care and obligatory noise measurements performed by employers. Smoking and solvent exposure were assessed with questionnaire. The study group was divided into subgroups with respect to the considered risk factors. In the analysis, the distribution of hearing level of each subgroup was compared to the predicted one which the standard calculation method described in ISO 1999:1990. For each of the considered risk factors, the difference between measured and calculated hearing level distribution was used to establish, by the least square method, a noise dose related correction square function for the standard method. The considered risk factors: solvent exposure, smoking and elevated blood pressure combined with noise exposure, may increase degree of hearing loss.

It was found that a total of 65 patients (66%) had a hearing loss (a threshold shift >20 dB HL) in the EHF range and the EHF hearing loss occurred more frequently in the tinnitus ear than in the non-tinnitus ear. The data also indicate that the EHF thresholds increased with the patient’s age and were in most patients higher in the tinnitus ear than in the non-tinnitus ear.

    Introduction: The Polish Universal Neonatal Hearing Screening Program (PUNHSP) is one example of a nationwide pro-health program in Poland. This program is aimed at early diagnosis and intervention in children with hearing impairment, and is an example of a well-managed program. Presenting the results of the PUNHSP, particularly organisational aspects and experience, can assist institutions managing other programs to achieve high efficiency. The aim of this work was to perform a detailed analysis of the PUNHSP by identifying the changes implemented over the 15 years it has been active, as well as the consequences of their introduction in terms of improved quality and efficiency. Materials and methods: Data from the PUNHSP, registered in the central database, were evaluated, as well as organisational information related to management, IT support and infrastructure. The analysis was based on quality assessment parameters (identification of changes and the purpose of their introduction) and effectiveness (consequences of introducing the changes). The analysis includes the 15-year period in which the PUNHSP has been active, from 2002 to 2017. Results: Thirteen main modifications of the program were identified according to the definition of “change”, in addition to 11 smaller modifications resulting from the necessity to adapt to current requirements. The changes were grouped into five categories: legal, administrative, management, audit and control, and IT. Discussion: The changes implemented in the PUNHSP can be assumed to have positively influenced various aspects of the program, but do not exhaust the possibilities for further optimisation of functioning. Conclusions: The program requires constant development in order to increase the efficiency and effectiveness of its operation, and the changes and solutions implemented in this program could be applied to improve existing pro-health programs, as well as those yet to be created.

    Hearing impairment caused by noise, traditionally called – depending on the duration of exposure - acute or chronic acoustic trauma, includes, in addition to presbyacusis, the most common adult population of hearing impaired. In Poland - according to the report of the Central Statistical Office (GUS, 2011), the number of workers employed in NDN exceeded the noise level (85 dB) is about 200 thousand, the highest in the mining, metal and metal products production, textiles and wood production. According to the Regulation of the Council of Ministers of on June 30, 2009, on the list of occupational diseases (Journal of Laws No. 132, item 1115), it is defined as "bilateral permanent hearing loss of the cochlear or sensory-nerve type, expressed as an increase in hearing threshold of at least 45 dB in the ear better heard, calculated as an arithmetic mean for frequencies 1,2 and 3 kHz. Hearing impairments also occur in the military and police during field training and in combat where the source of acoustic injuries are firearms and pulse-inducing explosions (as in some industries) with high C peak levels (Lc peak) Time to rise to a maximum of <1 ms. The prevalence of loud music listening, particularly by personal stereo players, is also affecting children and adolescents with audiometric hearing loss, according to the World Health Organization (WHO) estimates of around 15-20%. The preventive action strategy is defined by the European Union legislation and the national implementing legislation that reduces or eliminates the risk and reduces (if not eliminated), taking into account available technical and organizational solutions to minimize the risk of hearing damage. If you can not reduce the noise levels with technical and organizational methods, you need individual hearing protectors. Ear protectors may be equipped with electronic systems with active noise reduction (which can improve low and medium frequency performance), adjustable attenuation (improves speech intelligibility and perception of warning signals), and wireless communication for verbal communication.

    Opis:
    If we want to provide the efficient training intervention to increase the duration of using heating protection devices (HPDs) by workers, we need a tool that can estimate the person’s hearing threshold taking into account noise exposure level, age, and work history, and compare them with audiometry to find out the percent reduction of workers hearing loss. First, the workers noise exposure level was determined according to ISO 9612, then 4000 Hz audiometry was done to find age and work history. On basis of ISO 1999 the hearing threshold was estimated and if the hearing protection device was not used continuously and correctly, the hearing protection device’s actual performance was reduced adjusted with person’s audiometry. After training intervention, the estimate was done again and was compared with the adjusted audiometry. According to ISO 1999 standard estimation results, the percent reduction of the workers hearing loss level was 6.48 dB in intervention group. This level remained unchanged in control group. The mean score of hearing threshold estimation (standard ISO 1999) was statistically more significant than mean score of hearing threshold (p-value ¡ 0.001). The results show not significant change in control group due to Lack of changing of noise exposure level. In regards to the results of hearing threshold estimation based on ISO 1999 and comparing with workers audiometry, it can be seen that BASNEF training intervention increases the duration of Rusing the HPDs and it could be effective in reducing hearing threshold related to noise.

    Opis:
    Sudden onset sensorineural hearing loss is an emergency condition in otorhinolaryngology. Despite its common occurrence, the investigation and treatment of this condition are still controversial. Auditory brainstem response is one of hearing assessment tools used in sudden onset sensorineural hearing loss. However, its findings may be false positive at early stages of the disorder, leading to unnecessary investigations and treatments. We report two cases of idiopathic sudden onset sensorineural hearing loss, which manifested in abnormal auditory brainstem response during the acute phase of illness. However, a complete recovery of auditory brainstem response was observed after treatment completion. Therefore, we suggest that auditory brainstem response should be performed reasonably, especially during the acute phase of sudden onset sensorineural hearing loss.
    Nagły idiopatyczny niedosłuch czuciowo-nerwowy jest stanem nagłym w otorynolaryngologii. Pomimo częstego występowania badanie i leczenie tego zaburzenia nadal budzą kontrowersje. Jednym z narzędzi diagnostycznych stosowanych u pacjentów z nagłym idiopatycznym niedosłuchem czuciowo-nerwowym jest pomiar słuchowych potencjałów wywołanych pnia mózgu. Badanie to może jednak dawać wyniki fałszywie dodatnie we wczesnych stadiach choroby, prowadząc w konsekwencji do niepotrzebnych dalszych badań i prób leczenia. W pracy przedstawiono dwa przypadki nagłego idiopatycznego niedosłuchu czuciowo-nerwowego objawiającego się nieprawidłowościami w zapisie słuchowych potencjałów wywołanych pnia mózgu podczas ostrej fazy choroby. Po zakończeniu leczenia stwierdzono całkowite przywrócenie słuchu w badaniu słuchowych potencjałów wywołanych pnia mózgu. Autorzy zalecają wykonywanie tego badania w sposób racjonalny, w szczególności podczas ostrej fazy choroby.

    hearing loss treatment
    Opis:
    Introduction: It is estimated that hearing impediment affects approximately 12% of the population. Some forms of hearing disorders can be successfully treated conservatively, while in others surgery plays a key role. Often, therapeutic methods are exhausted and the patient faces the decision about the need for acoustic organ prosthesis. Depending on the causes of anomalies, apparatus for air conduction, bone conduction or cochlear implants are used. A cochlear implant replaces the damaged sensory cells of the inner ear. It constitutes an electronic prosthesis of the acoustic organ, composed of two parts. The internal part (implanted in the inner ear) consists of an implant and electrodes, which conduct electrical signals to the cochlea. The external part consists of a microphone, a speech processor, and a transmitter. Care report: A 70-year-old patient with deep hearing loss in the right ear and deafness of the left ear. During the interview, the patient denied mechanical injuries of the head and neck, acoustic trauma, inflammation or otorrhea. Based on the conducted tests, qualification otolaryngology, audiology, and otoneurology, radiology, surdologopedy and psychology were performed for cochlear implant insertion. The patient was qualified for cochlear implantation in the left ear under general anesthesia. The surgical team was composed of dr hab. Maciej Wiatr, prof. dr hab. Kazimierz Niemczyk, prof. dr hab. Jacek Składzień, MD Agnieszka Wiatr with anesthetic monitoring under the supervision of MD Renata Witkowska. The patient was discharged home on day 7 after surgery in good general and local condition. Simultaneous rehabilitation was started at the Center for Daily Rehabilitation of Hearing and Speech at the Specialist Center of Diagnosis and Rehabilitation for Children and Adolescents with Hearing Disabilities of the Polish Association of the Deaf in Cracow.

    Opis:
    Background: Patients with vestibular schwannoma (VS) most commonly present with hearing threshold reduction for high frequencies and a falling type of audiometric curve. However, it is doubtful whether all Pure Tone Averages described in the literature characterize patients with VS correctly, as the type of PTA which comprises higher frequencies may be more appropriate for hearing status assessment in those patients. Aim: The aim of this study was to analyze 3 common methods of calculating Pure Tone Averages (PTA1 – 500, 1000, 2000 and 3000 Hz; PTA2 – 500, 1000, 2000 and 4000 Hz; PTA3 – 500, 1000 and 2000 Hz) and to determine which of them is the most reliable for the assessment of VS patients. Material and Methods: The study group included 86 patients operated on due to vestibular schwannoma accessed via the middle cranial fossa. Results: Regarding the method of calculating Pure Tone Averages (PTA1, PTA2 and PTA3) identical or similar correlations were found between the preoperative values of Pure Tone Averages (PTA1, PTA2 and PTA3) and surgery-related hearing loss, as well as individual parameters of audiologic tests. Conclusions: Pure Tone Averages calculated according to 3 different methods (PTA1, PTA2, PTA3) may be used interchangeably in the assessment of hearing in VS patients.

    Opis:
    In this paper, we discuss the issue of hearing damage caused by noise in classical musicians. Long-term exposure to highintensity sounds leads to degenerative changes at the level of the cochlea and then in the higher parts of the auditory canal. This is particularly unfavorable for musicians because an efficient hearing organ is necessary for them to perform their daily work. The risk of hearing damage depends on noise parameters and intrinsic factors referred to as individual noise sensitivity. Not all musicians are exposed to sounds that exceed the acceptable level. However, most of them work at noise levels that are close to or above the acceptable safety limit, thus posing a health threat. In addition to hearing threshold elevation, tinnitus, hyperacusis, and diplacusis may result following many years of exposure to high-intensity acoustic stimuli. Although the differences between the hearing thresholds for instrumentalists and members of the unexposed population are not large, researchers emphasize the need to recognize musicians as a risk group and to apply appropriate prevention. One of the methods to prevent hearing damage is to use ear protectors, which, although effectively reduce exposure, are not widely used by instrumentalists as they impede auditory control over the sounds produced by the instrument. In addition, multifaceted prevention programs and various techniques to minimize exposure are used, such as the proper placement of loud instruments in an orchestra.

    Introduction: Nowadays, there are many options to treat hearing-impaired patients: tympanoplastic surgery, hearing aids and a wide range of implantable devices. Aim: The aim of this study is to present the mid-term audiological and quality of life benefits after the implantation of Osia®, an active piezoelectric bone conduction hearing implant. Material and methods: The state of the tissues in the implanted area, as well as audiological and quality of life results were analyzed at six, nine and twelve months after implantation in a group of four adult patients with bilateral mixed hearing loss (1 after bilateral canal-wall-down mastoidectomy, 2 with chronic simple otitis media and after myringoplasty in the opposite ear, 1 with bilateral otosclerosis and after stapedotomy in the opposite ear). Results: No postoperative complications were found in any of the cases. One year after surgery the mean audiological gain in FF PTA4 (pure tone average for 0.5, 1, 2, and 4 kHz) was 52.2 ± 3.5 dB in comparison to the unaided situation, the mean speech understanding with Osia® in quiet was 90 ± 8.2% for 50 dB SPL, 98.8 ± 2.5% for 65 dB SPL and 100 ± 0% for 80 dB SPL, and the mean speech understanding with Osia® in noise was 37.5% ± 23.6 for 50 dB SPL, 93.8 ± 4.8% for 65 dB SPL and 98.8 ± 2.5% for 80 dB SPL. There was also an evident improvement in the quality of hearing as well as in the quality of life, measured by APHAB (Abbreviated Profile of Hearing Aid Benefit) and SSQ (Speech, Spatial and Qualities of Hearing Scale). Conclusions: The Osia® is an effective treatment option for patients with bilateral mixed hearing loss. The mid-term audiological and quality of life results are excellent, but further observations including bigger groups of patients and a longer follow-up are required.

    Introduction: Stapedotomy is currently the surgical technique of choice for treating otosclerosis. Despite this, there is no agreement about the best technique to perform a small fenestra footplate, therefore multiple procedures have been proposed. The aim of this study was to investigate the hearing outcomes of microdrill and manual perforator. Material and Methods: An observational prospective study was carried out on patients who underwent stapedotomy. We analyzed the hearing threshold in two groups of patients according to the way the fenestra footplate was realized by microdrill or manual perforator. Results: A total of 113 patients were evaluated. Postoperative hearing gain of the microdrill group was 23.29 (18.58) dB HL 95% CI (18.40–28.18), while in the manual perforator group, it was 22.67 (12.91) dB HL 95% CI (19.07–26.26). Both groups were statistically significant. Postoperative bone conductive hearing threshold at the frequencies of 0.5, 1 and 2 KHz and postoperative air conductive hearing threshold at the frequencies of 2 and 4 KHz showed statistically significant differences in the manual perforator group. The closure of air-bone gap was higher in the microdrill group with statistically significant differences. Conclusion: Both manual perforator and microdrill have good hearing outcomes at six months after surgery. The manual perforator has better audiological outcomes than microdrill. Hence, the manual perforator is a safe technique and can be used in centers that do not have other methods to make the small fenestra.

    Opis:
    Evaluation of acoustic vestibular evoked myogenic potentials (AC-VEMPs) is one of the tests performed to assess the function of the balance system. Evaluation of acoustic ocular vestibular evoked myogenic potentials (AC-oVEMPs) consists in the measurement of potentials evoked within oculomotor muscles, particularly the inferior oblique muscles (the most superficial muscles) with impulses being transmitted along the superior branch of the vestibular nerve from the utricular macula. Despite the fact that the measurement of oVEMPs was introduced relatively recently, it has found widespread use as a diagnostic tool in otology and neurotology. Despite the growing number of literature reports, the methodology of the test and the methods for the interpretation of its results are still subject to debate. This article is dedicated to various aspects of AC-oVEMP tests, including the methodology of the test, interpretation of its results and potential use in the diagnostics of vertigo.

    Opis:
    Background: Hearing loss caused by excessive exposure to noise is one of the most common health risks for employees. One solution for noise reduction is the use of hearing protectors, which is a very effective method for protecting hearing from the workplace noise. In order to obtain better attenuation efficiency, custom moulded earplugs can be equipped with a suitable acoustic filter. The effectiveness of the hearing protectors’ attenuation is based on real measurement of hearing thresholds for normal hearing people with and without hearing protectors. However, this is a time consuming process, and the obtained values are characterised by quite large inter-individual variability. The optimal solution is to measure the attenuation characteristics based on the objective method (without the presence of the subject), the results of which will be in accordance with the results of subjective tests. Therefore, the main purpose of the research in this work was to measure the attenuation characteristics of the self-designed custom moulded earplugs with and without acoustic filters through the use of subjective and objective methods, and to compare the results in terms of the research methods. Methods: Measurements of the acoustic attenuation obtained by custom moulded earplugs with designed F1, F2, and F3 acoustic filters (internal diameters dF1 = 1:25 mm, dF2 = 0:85 mm, and dF3 = 0:45 mm), as well as full insert earplugs (without any acoustic filters) were carried out using two methods: objective and subjective. The objective measurements were carried out in an anechoic chamber. The artificial head (High-frequency Head and Torso Simulator Brüel & Kjær Type 5128) was located at a distance of 3 m, directly opposite the loudspeaker. The test signal in the measurements was pink noise – in the frequency range up to 12.5 kHz and the level 85, 90, and 95 dB. The hearing protectors with and without acoustic filters were mounted in the Head and Torso Simulator which was connected with Pulse System Brüel & Kjær. Five normal hearing subjects participated in the subjective measurements. A pink noise signal was used for one-third octave bands: 125, 250, 500, 1000, 2000, 4000, and 8000 Hz. The attenuation value was defined as the difference (in dB) between the hearing threshold of the test signal with a hearing protector and the hearing threshold determined without a hearing protector. Results: The results of the objective method proved that in addition to the significant impact of frequency on the attenuation values, the type of filter used in custom moulded earplugs also had a significant effect. In addition, the results of the objective method showed that in the whole frequency range the highest attenuation values are shown by the full earplugs, achieving slightly above 45 dB for frequency of 8 kHz. The attenuation values obtained from subjective measurements also confirmed that both the frequency and type of filter significantly affect the attenuation values of the tested hearing protectors. Conclusions: The results of this study did not confirm the hypothesis that the measurement method had no significant effect on the attenuation characteristics of self-designed custom moulded earplugs with different types of acoustic filters. The largest differences in attenuation values between the type of measurement methods occur for the low frequency band (250 Hz) and for higher frequencies (4000 Hz mainly). The change of the internal diameter of the F1 filter from 1.25 mm to 0.85 mm (F2 filter) did not significantly affect the attenuation characteristics.

    Shooting training is associated with exposure to a considerable amount of unique noise. We wanted to evaluate noise exposure during such training. Our observations especially apply to professional sport shooters, but they are also valid for shooting coaches/instructors. We collected acoustic signals in 10-, 25- and 50-m as well as open-air shooting ranges. The recorded material was analysed with orthogonal, adaptive parameterization by Shur. The mean duration of a single acoustic signal was 250–800 ms with the C-weighted sound peak pressure level of 138.2–165.2 dB. Shooters may be exposed to as many as 600–1350 acoustic impulses during a training unit. The actual load for the hearing organ of a professional shooter or a shooting coach is ~200 000 acoustic stimuli in a year-long training macrocycle. Orthogonal, adaptive parameterization by Shur makes safe scheduling of shooters’ training possible.

    Objective: A pure tone audiomety analysis of patients with extracranial complications of chronic suppurative otitis media (ECCSOM). Material and methods: We retrospectively analyzed audiometric data performed before treatment from 63 patients with ECCSOM (56 single, 7 multiple complications) including groups of frequencies. Results: The greatest levels of hearing loss were noted for 6 and 8 kHz (79.0 and 75.7 dBHL) and for the frequency groups high tone average (76.1 dBHL). As regards the severity of hearing impairment in pure tone average the prevalence of complications was as follows: labyrinthitis (77.8±33.6 dBHL), facial palsy (57.1±14.3 dBHL), perilymphatic fistula (53.9±19.9 dBHL) and mastoiditis (42.2±9.5 dBHL) (p=0.023). Conclusions: Hearing loss in ECCSOM is dominated by mixed, high-tone, moderate type of hearing loss, most profound in labyrinthitis. In 11% of patients the complication causes total deafness.

    Wstęp: Nowotwory mające swoją etiologię w gruczołach ślinowych występują rzadko i stanowią ok. 3–10% wszystkich guzów w obrębie głowy i szyi. Materiał i metody: W latach 2006–2016 w Klinicznym Oddziale Chirurgii Czaszkowo-Szczękowo-Twarzowej Wojskowego Instytutu Medycznego w Warszawie z powodu nowotworów ślinianek przyusznych hospitalizowano i leczono 149 pacjentów. Podstawą do analizy były historie chorób pacjentów, wyniki badań histopatologicznych oraz protokoły zabiegów operacyjnych. Wyniki: W 126 przypadkach guzy były łagodne, natomiast w 26 guzy złośliwe. Analizując wyniki można stwierdzić, że nowotwory - zarówno łagodne, jak i złośliwe – częściej występowały u mężczyzn. Średni wiek całej grupy badanych wynosił 58,3 lat, dla zmian złośliwych – 65,5 lat, a dla zmian łagodnych był nieznacznie niższy i wynosił 56,9 lat. Wśród pacjentów objętych analizą szczyt zachorowalności przypadał na przedział wiekowy 60–69 lat. Ponadto zwraca uwagę, iż przedział ten był taki sam dla ogólnej liczby guzów, jak i nowotworów łagodnych, natomiast dla nowotworów złośliwych był nieznacznie wyższy i wynosił 70–79 lat. Z analizy zebranego materiału wynika, że guzy łagodne występowały znamiennie częściej, stanowiąc 84,56% wszystkich guzów. Najczęstszymi rozpoznaniami wśród nowotworów łagodnych były gruczolak wielopostaciowy (adenoma pleomorphicum) oraz gruczolak limfatyczny (adenolymphoma), które stanowiły łącznie 93,66%. Rezultaty badań wskazują, że wśród nowotworów złośliwych dominowały: gruczolakorak polimorficzny o niskiej złośliwości (polymorphous low-grade adenocarcinoma) występujący w 26,07% przypadków, gruczolakorak inaczej nieokreślony (adenocarcinoma NOS) oraz rak zrazikowokomórkowy (acinic cell carcinoma). Każdy z nich stanowił po 13,04% rozpoznań. Jak wynika z przeprowadzonej analizy najczęstszą metodą leczenia było leczenie chirurgiczne jako metoda stosowana samodzielnie. Wnioski: Uzyskane z retrospektywnej analizy dane korelują z piśmiennictwem krajowym i światowym.

    Introduction: Upper respiratory tract infections are common childhood diseases. Children are more susceptible to middle ear infections because their Eustachian tube is short, straight and wide. As a consequence of these inflammatory changes while impaired patency of the Eustachian tube often arises conductive hearing. Objective: The aim of this study was to Assessment effectiveness of treatment Eustachian tube dysfunction using inhaler AMSA. Material and Methods: The study group comprised 30 patients. Same was in the control group. All patients reported conductive hearing loss. Test group was treated as an inhaler AMSA. The control group was treated pharmacologically. Patients were examined with the use of pure-tone audiometry, and impedance at baseline, after one week and four weeks. Results: Statistical analysis showed improvement in the studied parameters in patients treated with inhaler AMSA in a much shorter time than patients treated with pharmacotherapy.

    This paper presents risk factors of noise-induced hearing loss and harmful effects of noisy work environment on farmers. Longterm exposure to high-volume sounds leads to degenerative changes of ear structures. The paper presents the consequences of exceeding legal limits on noise exposure in agriculture. The risk of occupational noise exposure and its consequences, such as high frequency hearing loss, is significant in the group of farmers, regardless of whether they work in crop, livestock or mixed production.

    Opis:
    Introduction: For many years, surgical treatment of otosclerosis has been a widely accepted approach. Hearing improvement following stapes surgery is sometimes spectacular, and good treatment results are obtained in many centers in over 90% of patients. However, in the subsequent years after the treatment, some patients develop permanent or progressive conductive hearing loss. Aim: The aim of the study is to present a group of patients with conductive hearing loss after the first otosclerosis surgery and to analyze the causes of its occurrence. Materials and Methods: The retrospective review covered patients who underwent the initial surgery in the years 2000–2009. We analyzed the patients’ medical records from before the end of 2019, which provided results of at least 10 years of postoperative follow-up. The group consisted of 1118 patients aged 14–82, including 802 women and 316 men. Results: Reoperations due to conductive hearing loss were performed on 93 patients, who accounted for 8.3% of the originally operated patients. They were much more common in patients after stapedectomies (19.7%) than in patients after stapedotomy (5.5%). Prosthesis dislocation was found to be the most frequent intraoperative observation (44.1%) and was often associated with erosion or necrosis of the long process of incus (28%). Less frequent reasons for hearing loss were: adhesions around the prosthesis (10.8%), too small hole in the stapes footplate (8.6%), too short prosthesis (8.6%), progression of otosclerosis (7.5%), too long prosthesis (6.4%), presence of a granuloma around the prosthesis (5.4 %), and displacement of incus (4.3%). Conclusions: Surgical treatment of otosclerosis is a widely accepted and good method. It allows to achieve an improvement in hearing in the vast majority of patients treated in this way. Unfortunately, over the years some patients develop recurrent conductive hearing loss. Reoperation creates an opportunity for finding the cause and improving hearing in the majority of cases.

    Opis:
    Introduction Obstructive Sleep Apnea Syndrome (OSAS) is characterized by recurrent episodes of prolonged partial or complete obstruction of the upper airways. Several study groups studied the effect of snoring and OSAS on auditory function, showing an increase in the incidence of hearing loss in apneic patients, an earlier onset and/or a degree of hearing loss deeper than in peers. The aim of our study is to evaluate the audiological performance of a population of simple-snoring patients and patients suffering from mild OSAS, and the impact that such pathological condition can have on the auditory function, considering the significant levels of chronic noise. Materials and Methods Data was collected by analyzing audiometric exams on snoring patients and a control group of non-snoring patients. Our study included simple snoring patients without OSAS (AHI < 5) or with low level of OSAS (5< AHI < 15). Possible hearing loss was classified in a crescent scale (A-B-C-D-E), from greater to minor auditory performance, according to the indications of the national protocol of occupational medicine for evaluation of hearing loss in patients exposed to chronic noise. Results We have found independence between simple snorers, mild-OSAS snorers and non-snoring patients compared to the scale of hearing performance classification. Conclusions Our results show a distribution of hearing loss in the different groups that appear independent of the presence or absence of snoring, complicated or uncomplicated by mild OSAS.

    Opis:
    Introduction: The treatment and rehabilitation of hypoacusis with the use of cochlear implants is a safe and reliable method suitable for both children and adults. In people affected by chronic otitis media cholesteatomatosa or such who have previously undergone open repair of the ear, we use a special surgical technique known as lateral/subtotal petrosectomy. Material and methods: The study group consisted of patients with profound bilateral sensorineural hearing loss, in which otitis media with and without cholesteatoma has been diagnosed or after open repair of the middle ear. A retrospective analysis of patient data, as well as radiological and audiological results, was conducted. Results: In the Clinic of Otolaryngology and Laryngological Oncology of the Pomeranian Medical University in the years 2008–2018 we performed 90 cochlear implant surgeries, including a petrosectomy in 1 child with cholesteatoma (5 years) and in 2 adults after open repair (62 and 73 years). In all cases the procedure was done in a single stage. Healing proceeded correctly in all patients undergoing petrosectomy. The observation period ranges from 26 to 32 months, computed tomography examinations revealed no indirect characteristics of recurrent cholesteatoma. The patients remain under constant ENT supervision. The child has risk factors for autism and mental retardation, he displays good auditory responses and speech understanding; he has not developed active speech. As regarding free field pure tone audiometry, in adults hearing in the cochlear implant remains at 35 and 40 dB, and speech understanding at 80%. Discussion: Patients with chronic otitis media can be treated efficiently and safely with a cochlear implant using lateral petrosectomy. Lateral/subtotal petrosectomy is the access of choice when deep sensorimotor hearing loss coexists with chronic inflammation in the middle ear.

Among them the most ad-vanced changes are described in first type. In final stage it leads to deafness and blindness with possible balance dis-orders.This syndome is inherited in autosomal recessive way, but we have to note the occurence of genetical heterogeneity. It causes big diversity of symptoms intensification. Correct diagnosis is important in view of giving genetical advice and eventual diagnostic and terapeutic procedure.

    Introduction: Profound hearing loss significantly affects the quality of life of deaf people as well as their families. Observation of the benefit from the use of cochlear implants in deaf patients allows to assess the success of treatment with this method and its impact on the quality of life of these patients. The aim of this study was to determine the quality of life in patient after the cochlear implantation in the material of Department of Phoniatrics and Audiology of the Medical University in Poznań. Material and methods: The study involved implanted patients who voluntarily joined to the project entitled "Observational study of the implanted patient (Cochlear-IROS)". It has a prospective character, it is an international and long-term study, covering the observation of patients up to three years after implantation. Standardized HUI and SSQ questionnaires were used. 70 patients were included in the analysis, the mean age at the time of the cochlear implantation was 47.6 years. In the research group there were 33 men and 37 women. In the whole group, the patients' age at implantation was at least 18 years, max. 80 years. Results: The results of the SSQ questionnaire, which deals with the self-assessment of hearing ability in everyday situations, indicate that in the subjective assessment of patients one year after surgery the speech hearing improved by 77%, spatial hearing by 84%, and the quality of hearing by 49%. The general quality of life before the first connection of the sound processor according to the HUI questionnaire, the patients rated at 0.49 (0-1 scale, where 0 - corresponds to the death condition and 1 - full health). After one year from the implantation, this rating increased to 0.56. Conclusions: The implantation of the cochlear implant significantly increases the patient's quality of life, its physical and emotional functioning. Statistically significant better self-assessment of patients mainly concerned hearing speech and spatial hearing - especially after 1 year of connecting the speech processor.

    Noise in an underground coal mine has dominant components generated mainly from 3 sources: (a) continuous mining machines, (b) roof bolters, and (c) cars/vehicles used to transport personnel and/or coal. Each of these 3 noise sources also has a number of well-defined sub-sources with their own noise characteristics. Sound level meters were used to collect noise data in the form of instantaneous readings and also to check calibration of other sound measuring instruments. The most useful information was obtained from a spectrum analysis of continuous digital recordings of noise over time. This paper discusses the variability or dynamics of generated noise in both frequency and time domains in relation to several independent variables related to coal extraction and transportation processes.

    Opis:
    The aim of the study was to assess the hearing threshold levels (HTLs) in employees exposed to noise generated by low-frequency ultrasonic technological equipment in comparison with the HTLs of workers exposed to audible noise at the similar A-weighted equivalent-continuous sound pressure level. The study includes measurements of ultrasonic and audible noise at workplaces and hearing tests, i.e. conventional pure-tone audiometry and extended high-frequency audiometry. The study group comprised 90 workers, aged 41.4 ± 10.0 years (mean±SD), exposed for 17.3 ± 9.8 years to noise generated by ultrasonic devices at mean daily noise exposure level (‹LEX,8h›) of 80.6 ± 2.9 dB. The reference group consists of 156 subjects, exposed to industrial noise (without ultrasonic components) at similar A-weighted equivalent-continuous sound pressure level (‹LEX,8h› = 81.8 ± 2.7 dB), adjusted according to age (39.8 ± 7.7 years), gender and job seniority (14.0 ± 7.0 years). This group was selected from database collected in the Nofer Institute of Occupational Medicine. Audiometric hearing threshold levels in the frequency range of 0.5–6 kHz were similar in both groups, but in the frequency range of 8–12.5 kHz they were higher in the group of employees exposed to ultrasonic noise. The findings suggest that differences in the hearing threshold (at high frequencies) in analyzed groups may be due to differences in spectral composition of noise and show the need to continue the undertaken studies.

    Introduction. Ramsay Hunt syndrome is a clinical manifestation of varicella zoster virus reactivation. It is characterized by an erythematous vesicular rash in the external auditory canal and pinna with otalgia, vertigo and ipsilesional facial palsy. Symptoms develop over a few days with prodromal signs of facial weakness, tingling, facial numbness. Usually, cranial nerves VII and VIII are involved in the inflammatory process. Possible consequences of Ramsay Hunt syndrome are hearing loss, encephalitis and meningitis. Description of the case report. The authors present the case of a 63-year-old woman with a vesicular rash, earache, vertigo and left-sided facial paralysis who was treated with antiviral drugs and analgesics. These symptoms were complicated by conductive hearing loss in the left ear and meningitis. After treatment facial paralysis decreased. Unfortunately, hearing loss was permanent. Discussion. Rapid administration of antivirals and corticosteroids limited facial paralysis and improved facial expression. The prognosis for facial palsy is poorer in Ramsay Hunt syndrome than in idiopathic forms. Conclusions. A past history of vertigo and hypertension could been a predisposing factor for the severe manifestation of Ramsay Hunt syndrome and subsequent complications

    The aim of the study was to examine the relationship between tinnitus pitch and maximum heating loss, frequency range of hearing loss, and the edge frequency of the audiogram, as well as, to analyze tinnitus loudness at tinnitus frequency and normal hearing frequency. The study included 212 patients, aged between 21 to 75 years (mean age of 54.4 ± 13.5 years) with chronic subjective tinnitus and sensorineural hearing loss. For the statistical data analysis we used Chisquare test and Fisher’s exact test with level of significance p < 0.05. Tinnitus pitch corresponding to the frequency range of hearing loss, maximum hearing loss and the edge frequency was found in 70.8%, 37.3%, and 16.5% of the patients, respectively. The majority of patients had tinnitus pitch from 3000 to 8000 Hz corresponding to the range of hearing loss (p < 0.001). The mean tinnitus pitch was 3545 Hz ± 2482. The majority (66%) of patients had tinnitus loudness 4-7 dB SL. The mean sensation level at tinnitus frequency was 4.9 dB SL ± 1.9, and 13 dB SL ± 2.9 at normal heating frequency. Tinnitus pitch corresponded to the frequency range of hearing loss in majority of patients. There was no relationship between tinnitus pitch and the edge frequency of the audiogram. Loudness matching outside the tinnitus frequency showed higher sensation level than loudness matching at tinnitus frequency.

    Opis:
    Background: Ocular vestibular-evoked myogenic potential (oVEMP) is one of recently introduced tests used to assess the function of the equilibrium system. It is still under research and no consensus has been reached yet. Aim: To analyze AC-oVEMP response parameters in subjects with no history of neurological or vestibular deficits. Material and Methods: The AC-oVEMPs collected from 50 subjects (100 ears) were analyzed in this prospective study for the response presence in the time domain, the latencies and amplitudes of the waves. Results: No statistically significant differences were observed between the right and left ear considering both N1 latency, and amplitude. Significant differences were noted when comparing the groups <40 yo vs ≥40 yo (shorter latencies and higher amplitudes were observed in subjects <40). Conclusions and Significance: This thorough AC-oVEMP analysis in a group of healthy volunteers facilitated the proposal of reference ranges with a simultaneous indication of age-related differences. Shorter oVEMP latencies and higher amplitudes were observed in subjects <40 yo, while in the subjects ≥40 yo the latencies were longer and the amplitudes lower.

    Opis:
    The aim of the study study was to model, with the use of a neural network algorithm, the significance of a variety of factors influencing the development of hearing loss among industry workers. The workers were categorized into three groups, according to the A-weighted equivalent sound pressure level of noise exposure: Group 1 (LAeq < 70 dB), Group 2 (LAeq 70-80 dB), and Group 3 (LAeq > 85 dB). The results obtained for Group 1 indicate that the hearing thresholds at the frequencies of 8 kHz and 1 kHz had the maximum effect on the development of hearing loss. In Group 2, the factors with maximum weight were the hearing threshold at 4 kHz and the worker’s age. In Group 3, maximum weight was found for the factors of hearing threshold at a frequency of 4 kHz and duration of work experience. The article also reports the results of hearing loss modeling on combined data from the three groups. The study shows that neural data mining classification algorithms can be an effective tool for the identification of hearing hazards and greatly help in designing and conducting hearing conservation programs in the industry.

    The aim of the study was to analyse the status of SE in people who are deaf or hard of hearing (D/HH) and compare SE scores between active and inactive individuals. The sample of people who are D/HH (n=117) was divided into two groups of those who are regularly participating in sport (active ; n=27) and those who are not participating in any sport in their leisure (inactive ; n=90) . The Rosenberg Self - Esteem Scale (RSES) was used as a primary research method. 10 - item scale measures global self - worth by me asuring positive and negative feelings about the self. Higher scores (from 10 to 40 points) indicate higher SE. The Pearson chi - square test was used to determine the differences of 10 RSES items and total scores between active and inactive people who are D /HH. We found that t he mean score of RSES in the group of people who are D/HH was 28.83 points; active people who are D/HH observed total score of RSES 30.18 points and group of inactive people who are D/HH showed the lowest SE by achieving 28.89 points. M ean scores comparison of each RSES item between active and inactive people who are D/HH revealed higher SE in the group of active people with hearing loss. Significantly higher SE of active people who are D/HH was presented only by 1 from 10 RSES items . Th e results of our study confirmed that actively living people with hearing loss have higher SE comparing those who are living sedentary life style.

    Background: The aim was to present the methodology and interpretation of intraoperative hearing monitoring with simultaneous Transtympanic Electrocochleography (TT-ECochG) and direct Cochlear Nerve Action Potential (CNAP) measurements during vestibular schwannoma removal. Materials and Methods: Detailed methodology of measurements and interpretation of results are presented in three exemplary patients who underwent tumor removal via middle fossa approach (MFA) with the use of intraoperative monitoring of hearing with TT-ECochG and direct CNAP performed in real time. In addition, all responses were automatically recorded and stored along with surgical information and subjected to detailed analyses and calculation after surgery. Results: The following changes in TT-ECochG and direct CNAP responses were observed: Patient #1 – TT-ECochG and CNAP responses with minor, but transient, morphology changes (hearing was preserved); Patient #2 – CNAP responses changed significantly but, temporarily, from triphasic into biphasic responses later, with marked but partially reversible desynchronization of CNAP; changes in TT-ECochG responses were also observed but, at the end, returned to baseline (surgery-related deterioration of hearing); Patient #3 – irreversible changes of TT-ECochG and direct CNAP (complete loss of hearing). Conclusions: A combination of TT-ECochG and direct CNAP allows for real-time monitoring of auditory function during vestibular schwannoma resection and surgical manipulation which contribute to the risk of hearing loss. Therefore, the surgeon can be instantly informed about changes which could increase the possibility of preserving the patient’s hearing

    Opis:
    The overall purpose of this study was to assess hearing status in professional orchestral musicians. Standard pure-tone audiometry (PTA) and transient-evoked otoacoustic emissions (TEOAEs) were per- formed in 126 orchestral musicians. Occupational and non-occupational risk factors for noise-induced hearing loss (NIHL) were identified in questionnaire inquiry. Data on sound pressure levels produced by various groups of instruments were also collected and analyzed. Measured hearing threshold levels (HTLs) were compared with the theoretical predictions calculated according to ISO 1999 (1990). Musicians were exposed to excessive sound at weekly noise exposure levels of for 81-100 dB (mean: 86.6±4.0 dB) for 5-48 years (mean: 24.0±10.7 years). Most of them (95%) had hearing corresponds to grade 0 of hearing impairment (mean hearing threshold level at 500, 1000, 2000 and 4000 Hz lower than 25 dB). However, high frequency notched audiograms typical for noise-induced hearing loss were found in 35% of cases. Simultaneously, about 35% of audiograms showed typical for NIHL high frequency notches (mainly occurring at 6000 Hz). When analyzing the impact of age, gender and noise exposure on hearing test results both PTA and TEOAE consistently showed better hearing in females vs. males, younger vs. older musicians. But higher exposure to orchestral noise was not associated with poorer hearing tests results. The musician’s audiometric hearing threshold levels were poorer than equivalent non-noise-exposed population and better (at 3000 and 4000 Hz) than expected for noise-exposed population according to ISO 1999 (1990). Thus, music impairs hearing of orchestral musicians, but less than expected from noise exposure.

    risk of noise-induced hearing loss
    Opis:
    This study aimed to assess exposure to sound and the risk of noise-induced hearing loss (NIHL) in orchestral musicians. Sound pressure level was measured in 1 opera and 3 symphony orchestras; questionnaires were filled in. On the basis of that data, the risk of NIHL was assessed according to Standard No. ISO 1999:1990. Classical orchestral musicians are usually exposed to sound at equivalent continuous A-weighted sound pressure levels of 81−90 dB (10th−90th percentiles), for 20−45 h (10th−90th percentiles) per week. Occupational exposure to such sound levels over 40 years of employment might cause hearing loss (expressed as a mean hearing threshold level at 2, 3, 4 kHz exceeding 35 dB) of up to 26%. Playing the horn, trumpet, tuba and percussion carries the highest risk (over 20%).

    Opis:
    INTRODUCTION Congenital cytomegalovirus (CMV) infection is a cause of sensorineural hearing loss (SNHL) in children. Symptomatic CVM is present in 5–10% of children with this disease and typical clinical signs of congenital cytomegalovirus infection are: microcephalia, mental retardation, progressive major amblyacousia, neuromuscular infection and ocular complications. One percent of live births has cytomegalovirus infection, 90% neonates with perinatal infection do not show symptoms of the disease. It is believed that symptomatic CMV is associated with a 90 % risk of neurological sequelae including hearing loss, or a risk of ophthalmic disorders. Ophthalmological symptoms of congenital CMV infection may affect between 5% and 30% of children. Most are disorders of the posterior segment of the eye such as retinochorioiditis, macular scars and peripheral retina, optic nerve atrophy and uveitis. Pathology of the anterior segment of the eye exists in the form of congenital cataract and corneal scarring. It is believed that with congenital CMV infection, strabismus, microphthalmia or lack of eyeball may coexist. Hypoacusis occurs in 30–60% of children with congenital symptomatic CVM. . The aim of the paper is to present the audiological examination schema in our Clinic for patients with CMV infection, involving the tonal audiometry threshold and objective hearing organ testing, as well as the ophthalmological view on these infections. MATERIAL AND METHOD The study group consisted of 30 children with cytomegalovirus infection at the age of 2–12 years, hospitalized at the Instytucie Centrum Zdrowia Matki Polki (Institute of Polish Mother's Health Center) in Lodz. 22 of them (73%) had congenital cytomegalovirus, 8 (27%) acquired cytomegalovirus. RESULTS AND DISCUSSION In the cases of congenital CMV infection, half of the patients in our study had bilateral profound sensorineural hearing loss (in pure tone audiometry threshold curves of air and bone conduction at low and medium frequencies of 70 dB, while for frequencies above 2000 Hz at 90 dB). The presence of wave V in the ABR examination was recorded on both sides at the level of 90 dB. Bilateral sensorineural hearing losses were associated with mental and physically retardation, brain malformation and microcephalia. In the group of children with acquired CMV, we did not observe hearing loss. CONCLUSIONS This research proved that only congenital cytomegalovirus infection caused hearing loss. In spite of this, all children with congenital and acquired CMV should be consistently controlled by an audiologist and ophthalmologist.
    W S T Ę P Wrodzone zakażenie wirusem cytomegalii (Cytomegalovirus – CMV) jest jedną z najczęstszych infekcji wewnątrzmacicznych. Postać objawowa zakażenia występuje u 5–10% dzieci z tą chorobą i najczęściej charakteryzuje się objawami klinicznymi pod postacią: małogłowia, niedorozwoju umysłowego, ciężkiego uszkodzenia słuchu o charakterze postępującym, zakażeń nerwowo-mięśniowych i powikłań ocznych. Uważa się, że objawowa cytomegalia jest związana z 90-procentowym ryzykiem wystąpienia następstw neurologicznych, w tym uszkodzenia słuchu czy zaburzeń okulistycznych. Objawy okulistyczne wrodzonego zakażenia CMV mogą dotyczyć od 5 do 30% dzieci. Najczęściej stwierdza się zaburzenia tylnego odcinka gałki ocznej, takie jak retinochorioiditis, blizny w plamce oraz siatkówki obwodowej, zanik nerwu wzrokowego oraz zapalenie błony naczyniowej. Patologia odcinka przedniego oka przyjmuje postać zaćmy wrodzonej oraz blizn rogówki. Uważa się, że z wrodzonym zakażeniem CMV mogą współwystępować zez, małoocze czy brak gałki ocznej. Niedosłuch pojawia się u około 30–60% dzieci z objawową cytomegalią wrodzoną. Celem pracy było przedstawienie audiologicznej ścieżki diagnostycznej oraz obrazu okulistycznego u dzieci w przebiegu zakażenia CMV. M A T E R I A Ł I M E T O D A Badaniem objęto 30 dzieci zakażonych CMV w wieku od 2 do 12 lat, hospitalizowanych w Instytucie Centrum Zdrowia Matki Polki w Łodzi. U 22 dzieci (73%) stwierdzono cytomegalię wrodzoną, natomiast u 8 (27%) cytomegalię nabytą. WYNIKI I O M Ó W I E N I E W przypadkach wrodzonej postaci zakażenia ponad połowa badanych w naszym materiale miała obustronny głęboki niedosłuch odbiorczy (w audiometrii tonalnej progowej krzywe przewodnictwa powietrznego i kostnego w zakresie niskich i średnich częstotliwości na poziomie 70 dB, natomiast dla częstotliwości powyżej 2000 Hz na poziomie 90 dB). Obecność fali V w badaniu ABR zarejestrowano obustronnie na poziomie 90 dB. W pracy przedstawiono schemat prowadzonych badań audiologicznych u dzieci z CMV, obejmujących audiometrię tonalną progową i obiektywne badania narządu słuchu.

    Opis:
    Ménière’s disease is characterized by sudden episodes of vertigo accompanied by tinnitus and/or feeling of fullness in the ear as well as fluctuating sensorineural hearing loss. Despite numerous studies, the etiology of this disease remains unknown. However, the enlargement of the inner ear’s endolymphatic spaces, referred to as endolymphatic hydrops, is considered the underlying condition. Thanks to recent advances in magnetic resonance (MR) technology, it is now possible to obtain in vivo imaging of endolymphatic hydrops in patients presenting with Ménière’s disease symptoms. Visualization of the inner ear fluid compartments is achieved after gadolinium contrast is administered into the tympanic cavity or via the intravenous route. Evaluation of endolymphatic hydrops is possible as the contrast agent selectively penetrates the perilymph, and endolymph is visualized as contrast defects. The currently used radiological hydrops grading systems include qualitative, semi-quantitative, and volumetric scales. The methods are subject to ongoing modifications to increase their sensitivity and specificity. Numerous studies describe correlations between clinical symptoms and audiological and otoneurological examination results with the endolymphatic hydrops grade. MRI is also applicable in patients’ diagnostics with an incomplete or atypical course of the Ménière’s disease. In the course of the treatment, follow-up MRI scans enable assessing individual treatment modalities’ efficacy in terms of the severity of lesions and the further course of the disease within the inner ear.

    We present an overview of current diagnostic and therapeutic guidelines on Ménière’s disease. Over the last five years, four studies on this subject have been published. In 2015, five Societies including the Classification Committee of the Barany Society, Japan Society for Equilibrium Research, EAONO - European Academy of Otology and Neurotology, AAO-HNS - American Academy of Otorhinolaryngology - Head Neck Surgery, and Korean Balance Society have issued updated guidelines on the diagnosis and treatment of Ménière’s disease. Other multi-center publications have since been published as well such as the International consensus (ICON) on treatment of Ménière’s disease 2018, European Position Statement on Diagnosis, and Treatment of Meniere’s Disease, Diagnostic and therapeutic strategy in Ménière’s disease, Guidelines of the French Otorhinolaryngology - Head and Neck Surgery Society (SFORL) 2017. The above-listed recommendations include the most recent diagnostic advancements (e.g. inner ear MRI) and new electrophysiological tests, but also discuss other commonly used treatment modalities, result reporting and they take into account the quality of life of the patients following treatment. We present the main clinical challenges in managing Ménière’s disease, principles of diagnosis as well as the treatment introduced at our center. Finally, we discuss fundamental updates contained in the published papers.

    Opis:
    The loss of cognitive function, in addition to physiological changes, is the main illness of patients in geriatric units. There are many factors affecting cognitive ability in elderly patients. Undoubtedly, one of them is the physiological aging process of the hearing organs. One of the methods to assess cognitive functioning is the Mini-Mental Sade Examination (MMSE). The paper presents an assessment of the impact of hearing aids in patients with hearing loss on the outcome of cognitive assessment in MMSE. Analysis of the study results provides answers to questions about the improvement of mental functioning in geriatric patients with hearing loss assessed by MMSE after starting to wear hearing aids.
    Utrata funkcji poznawczych jest obok zmian fizjologicznych głównym schorzeniem pacjentów oddziałów geriatrycznych. Istnieje wiele czynników wpływających na zdolności kognitywne pacjentów w podeszłym wieku. Niewątpliwie jednym z nich jest fizjologiczny proces starzenia się narządu słuchu. Jedną z metod oceny funkcjonowania poznawczego jest Krótka Skala Oceny Stanu Psychicznego (Mini-Mental Sade Examinotion – MMSE). W pracy przedstawiono ocenę wpływu zaprotezowania słuchu aparatami słuchowymi u pacjentów z niedosłuchem na wynik oceny czynności poznawczych w teście MMSE. Analiza wyników przeprowadzonych badań dostarcza odpowiedzi na pytania dotyczące poprawy funkcji umysłowych u pacjentów geriatrycznych z niedosłuchem, ocenianych metodą MMSE po zaprotezowaniu słuchu aparatami słuchowymi.

    Objective: Self-report questionnaire is informative to assess general hearing disability. The aims of this study were to investigate the reliability of Turkish version of spatial hearing questionnaire (SHQ) and to analyze the validity of the SHQ by the correlation with speech, spatial, and qualities of hearing questionnaire (SSQ) and Turkish matrix sentence test (TMST). Methods: The first part of the study was the psychometric properties of the SHQ with 192 participants (137 with normal hearing, 55 with hearing loss). In the second and main part of the study, we applied two questionnaires (SHQ and SSQ) and TMST to people other than those included in the first part of the study (88 participants with bilateral sensorineural hearing loss). We compared the results of these two questionnaires and the TMST with the speech discrimination (SD) scores. Results: Turkish spatial hearing questionnaire’s internal consistency was 0.94 and 0.97 for individuals with normal hearing and for individuals with hearing loss, respectively. Moderate, positive, statistically significant correlation was observed between the SHQ and SSQ (r = 0:606, p = 0:001 in individuals with hearing loss who do not wear any hearing aid, and r = 0:627, p = 0:001 in hearing aid users), and SHQ and SD (r = 0:561, p = 0:032 in hearing aid users). According to TMST, moderate, positive, statistically significant correlation was found between SSQ and adaptive TMST in individuals with hearing loss who do not wear any hearing aid (r = 0:330, p = 0:033 for S0N90 and r = 0:364, p = 0:018 for S0N270). Conclusions: Turkish SHQ is a valid and reliable questionnaire for assessing hearing functions. SHQ, SSQ, and TMST are clinically beneficial measuring tools in planning the process of hearing rehabilitation and follow-up.

    Opis:
    This study is a meta-analysis of the previous epidemiological studies which investigated the quantitative estimates of the association between independent or combined exposure to noise and mixed organic solvents and hearing loss until October 2014. Overall, 15 studies with information on 7530 individuals (6% female) were included. Having assessed – by puretone audiometry – the adjusted odds ratio estimates for the association between solvents mixture exposure and the risk of developing hearing loss stood at 2.05 (95% confidence interval (CI): 1.44–2.9). Similarly, for subjects who were concurrently exposed to noise and solvents mixture, an OR of 2.95 (95% CI: 2.1–4.17) was obtained. There was some evidence of heterogeneity within each of the 2 exposure groups (p heterogeneity < 0.001). This heterogeneity was not explained by differences in strength of effect between duration of exposure, the number of solvent and exposure index in subgroups of solvents mixture exposure. Based on the available data, our analysis has provided the evidence of increased risk of developing hearing loss for workers exposed to organic solvents even at quite low concentration. Moreover, if such exposure is accompanied by noise, it will exacerbate the extent of hearing loss. Int J Occup Med Environ Health 2017;30(4):521–535

    Opis:
    Objectives Hearing loss is a major worldwide health issue affecting an estimated 1.5 billion people. Causes of hearing loss include genetics, chemicals, medications, lifestyle habits such as smoking, and noise. Noise is probably the largest contributing factor for hearing loss. Noise arises from the workplace, ambient environment, and leisure activities. The easiest noise sources to control are workplace and environmental. Workplace noise is unique in that the employer is responsible for the noise and the worker. Also, workers may be exposed to much higher levels of noise than they would accept elsewhere. Employers follow the traditional hierarchy of controls (substitution/engineering, administrative, personal protective equipment [PPE]). Substituting or engineering a lower noise level actually reduces the hazard present to the worker but demand more capital investment. Administrative and PPE controls can be effective, but enforcement and motivation are essential to reducing risk and there is still some hearing loss for a portion of the workers. The challenge is to estimate the costs more clearly for managers. A systems engineering approach can help visualize factors affecting hearing health. Material and Methods In this study, a systems engineering causal loop diagram (CLD) was developed to aid in understanding factors and their interrelationships. The CLD was then modeled in VenSim. The model was informed from the authors’ expertise in hearing health and exposure science. Also, a case study was used to test the model. The model can be used to inform decision-makers of holistic costs for noise control options, with potentially better hearing health outcomes for workers. Results The CLD and cost model demonstrated a 4.3 year payback period for the engineered noise control in the case study. Conclusions Systems thinking using a CLD and cost model for occupational hearing health controls can aid organizational managers in applying resources to control risk.

    Opis:
    The article presents results of the work on creation of an application for Android mobile devices to perform hearing screening using pure-tone air conduction audiometry. The application was created in accordance with the procedure defined in the ISO 8253-1: 2010 standard and is to serve the widest possible group of people in a domestic environment, using headphones included with mobile devices. The effectiveness of the application was verified by performing comparative hearing tests on a representative group of patients with different hearing status. Validation was performed using the Interacoustics AD629 clinical audiometer and procedures adopted in the standards. The results of the test comparison were satisfactory. The mean error of the hearing threshold tested using the mobile application, compared to the clinical audiometer was 5.2 dBHL. In addition, the hearing threshold curves for the mobile application are similar in shape to the hearing thresholds for the clinical audiometer and coincide with the auditory experiences of the patients.
    Artykuł przedstawia wyniki prac nad stworzeniem aplikacji na urządzenia mobilne z systemem Android w celu wykonania przesiewowych badań słuchu w zakresie progowej audiometrii tonalnej przy przewodnictwie powietrznym. Aplikacja została stworzona zgodnie z procedurą określoną w normie ISO 8253-1:2010 i ma służyć jak najszerszej grupie osób w domowych warunkach badań przy wykorzystaniu słuchawek dedykowanych urządzeniom mobilnym. Działanie aplikacji zostało zweryfikowane poprzez wykonanie porównawczych badań słuchu na reprezentatywnej grupie pacjentów o zróżnicowanym stanie słuchu. Walidację przeprowadzono przy użyciu audiometru klinicznego Interacoustics AD629 i procedur przyjętych w normach. Wyniki badań porównawczych okazały się zadowalające. Średni błąd zbadanego progu słyszenia przy pomocy aplikacji mobilnej, w porównaniu do badań przeprowadzonych przy pomocy audiometru klinicznego, wyniósł 5.2 dBHL. Dodatkowo, krzywe progu słyszenia dla aplikacji mobilnej są zbliżone w kształcie do krzywych progu słyszenia dla audiometru klinicznego i pokrywają się z wrażeniami słuchowymi pacjentów.

    Opis:
    The publication presents partial results of hearing screening tests conducted in 2019 among employees of 37 hard coal mines located in the Śląskie and Małopolskie voivodships. The tests were carried out in different cities of both voivodships using the Mobile Hearing Diagnosis Center, which parked near the selected mine and specialized hearing diagnostics points of the ACSłuchmed Sp. z o. o. from Lublin. At the diagnostic points, detailed total audiometry tests were conducted on people diagnosed with hearing disorders as part of screening tests. The obtained results allowed to identify branches and workplaces with the highest risk of noise hazard in mines. The presented publication shows the results of noise measurement during blasting works and the results of anonymous surveys conducted among employees of the Department of Blasting Technology of hard coal mines. The survey concerned the subjective feelings of employees regarding noise levels at the workplace and its impact on their well-being and state of health. In the publication summary, the author draws attention to the need to take measures to constantly control the noise level at the workplace and introduce solutions that will enable its reduction and allow for better protection of employees against its damaging consequences.

    Opis:
    The contemporary labor market is characterized by high volatility and instability. It causes difficulty in adjusting to it of many unemployed people, especially graduates. This adaptation is more difficult if the person has some kind of disability. Research indicates that transitions from school to the labor market is particularly difficult for people with hearing impairment, even more than for people with other disorders or disabilities. The aim of the article is to introduce the reader to the situation of the deaf and hard of hearing in the context of their performance in the labor market. In the first part, the author reviews the research literature, while the second presents her own research in a group of 31 adult unemployed people with hearing loss. The research aimed at describing their perception of work as a whole, the perception of the specific situation of people with hearing loss in the labor market, the perception of the benefits and features of professional work and the characteristic features of a “good job”. The results lead to important implications for the education of the deaf and hard of hearing, so as to heighten their chances of employability.
    Współczesny rynek pracy charakteryzuje się dużą zmiennością i niestabilnością, co powoduje trudności w dostosowaniu się do jego realiów wielu bezrobotnych, zwłaszcza absolwentów. To przystosowanie się jest jeszcze trudniejsze, jeśli osobie towarzyszy jakaś niepełnosprawność. Badania wskazują, że tranzycja ze szkoły na rynek pracy jest szczególnie trudna dla osób z wadą słuchu. Celem artykułu jest przybliżenie czytelnikowi sytuacji osób niesłyszących i słabosłyszących w kontekście ich funkcjonowania na rynku pracy. W pierwszej części autorka dokonuje przeglądu literatury badawczej, natomiast w drugiej prezentuje własne badania w grupie 31 dorosłych bezrobotnych osób z wadą słuchu, określając ich postrzeganie pracy jako takiej, sytuacji osób z wadą słuchu na rynku pracy, dostrzeganie korzyści, jakie daje praca zawodowa, oraz cech dobrej pracy. Wyniki badań prowadzą do istotnych wskazówek co do edukacji osób niesłyszących i słabosłyszących, dzięki którym może wzrosnąć zatrudnialność (employability) osób z wadą słuchu.

    Opis:
    Over thirty years of progress in development of surgical techniques and cochlear implant technology led to a change in approach and extending of indications for qualifying patients to treatment of sensorineural hearing loss. Basic indications for cochlear implants include bilateral deafness, bilateral residual hearing or profound bilat-eral sensorineural hearing impairment as well as lack of acoustic gain from classic air conduction hearing aids af-ter a minimum of 5-6 months of use. Methods of subjective and objective hearing assessment are applied. Psycho-logical evaluation is aimed at assessing expectations of the patient/child’s parents, motivation, and intellect with regard to the presence of deficits that might pose difficulty in the course of further rehabilitation as well as accep-tance of this new type of stimulation. Speech and language evaluation takes into consideration the current level of speech development, articulation disorders related to hearing impairment, and the way to communicate with the environment. Final qualification requires imaging diagnostics of the head/ears (CT and/or MRI). Our surgi-cal experience allowed for implanting children with various congenital anomalies of the inner ear. Inflammation within the tympanic cavity and air-filled spaces of the mastoid process might require removal of inflammatory foci prior to surgery or selection of different surgical approach.

    Introduction: Surgical treatment of conductive hearing loss runs the risk of damage to the inner ear in the mechanism of acoustic trauma. Aim: The aim of this study was to evaluate the function of the organ of Corti, expressed as bone conduction threshold at the frequency of 4000 Hz for selected operations: mastoidectomy and canal-wall-down procedure. Material and methods: The material was collected from patients with chronic otitis media in the Department of Otolaryngology and ENT Oncology, Collegium Medicum of Nicolaus Copernicus University in Bydgoszcz in 2004–2009. All patients were examined with pure tone audiometry threshold before surgery and at least three years after surgery. The analyzed group of patients was divided into subgroups depending on the type of operation according to To classification and procedures for resection: mastoidectomy and canal-wall-down procedure. The results were statistically analyzed. Results: In the analyzed period of three years after surgery there was no statistically significant difference between groups, although there were higher values for tympanoplasty type 1 with mastoidectomy compared with tympanoplasty type 1 without mastoidectomy - respectively 25.67 dB and 18.53 dB. In the study, there was no statistically significant the difference in bone conduction threshold for frequency 4000 Hz within the type 2 tympanoplasty according to Tosa comparing canal wall-up and canal-wall-down procedure. Conclusions: Mastoidectomy or canal-wall-down procedure do not affect the bone conduction threshold for a frequency of 4000 Hz after tympanoplasty in long-term observation.

    Opis:
    The study presents evaluating the effectiveness of the hearing aid fitting process in the short-term use (7 days). The evaluation method consists of a survey based on the APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire. Additional criteria such as a degree of hearing loss, number of hours and days of hearing aid use as well as the user’s experience were also taken into consideration. The outcomes of the benefit obtained from the hearing aid use in various listening environments for 109 hearing aid users are presented, including a degree of their hearing loss. The research study results show that it is possible to obtain relevant and reliable information helpful in assessing the effectiveness of the short-term (7 days) hearing aid use. The overall percentage of subjects gaining a benefit when communicating in noise is the highest of all the analyzed and the lowest in the environment with reverberation. The statistical analysis performed confirms that in the listening environments in which conversation is held, a subjective indicator determined by averaging benefits for listening situations individually is statistically significant with respect to the degree of hearing loss. Statistically significant differences depending on the degree of hearing loss are also found separately for noisy as well as reverberant environments. However, it should be remembered that this study is limited to three types of hearing loss, i.e. mild, moderate and severe. The acceptance of unpleasant sounds gets the lowest rating. It has also been observed that in the initial period of hearing aid use, the perception of unpleasant sounds has a big influence on the evaluation of hearing improvement.

    Aim: To evaluate acoustically evoked cervical and ocular vestibular miogenic potentials (AC cVEMP and oVEMP) in patients with Susac’s syndrome. We did not seek for a diagnostic replacement test in those patients, but we investigated if the combined application of AC cVEMP and oVEMPs might be helpful as an additional source of information about the disease. Material and methods: To record VEMPs, the EMG standardization method was used to continuously monitor and minimize the variability of the recordings. The stimuli were presented unilaterally one ear at a time. The waveforms were analyzed for the response, latency and amplitude. Susac’s syndrome is a rare disease and two patients were analyzed in this study. Results: In patient #1 stimulation resulted in responses on both sides with latencies within normal and symmetry limits for both c- and oVEMPs; however, the responses presented small amplitudes for cVEMPs. In patient #2, only cVEMPs were present. The P1 latencies were within normal values but amplitudes were low, in addition showing asymmetry between sides, with right side amplitude being smaller. Conclusion: The information provided by the combined application of AC cVEMP and oVEMP might be useful in the diagnostics of Susac’s syndrome revealing additional information about the affected vestibular system and be of help in the treatment and rehabilitation planning.

    Opis:
    Wideband tympanometry (WBT) is a relatively new assessment method of the middle ear. Using wideband click WBT provides measurements at frequencies from 226–8000 Hz with more diagnostic information without any additional effort. The traditional impedance audiometry offers information acquired only at a single frequency (mostly 226 Hz or 1000 Hz). WBT provides both traditional tympanograms and tympanograms at multiple frequencies as well as new information that is retrieved from resonance frequency, absorbance graph, and averaged wideband tympanogram. WBT seems to be more specific and sensitive method to evaluate a conductive hearing loss than traditional impedance audiometry, and might be helpful in diagnosing such pathologies as: middle ear effusion, negative middle ear pressure, otosclerosis, ossicular discontinuity, tympanic membrane perforation, upper semicircular canal dehiscence. WBT seems to be a very promising additional diagnostic tool used for hearing screening in newborns and diagnosing minor middle ear pathologies that disturb otoacoustic emissions. WBT is considered to be a better predictor for middle ear problems in newborns and infants than 1000 Hz tympanometry. The wideband absorbance measurements can be performed at ambient as well as peak pressure. Ambient pressure absorbance measurements do not require any pressure changes in the external auditory canal, thus it seems to be a perfect method for post-surgical monitoring of middle ear condition. However, WBT has its limitations, it presents large inter-subject variability in both absorbance graphs and resonance frequency values, and therefore WTB should be more extensively studied. WBT see

    Opis:
    Noise induced hearing loss (NIHL) as one of the major avoidable occupational related health issues has been studied for decades. To assess NIHL, the excitation pattern (EP) has been considered as one of the mechanisms to estimate the movements of the basilar membrane (BM) in the cochlea. In this study, two auditory filters, dual resonance nonlinear (DRNL) filter and rounded-exponential (ROEX) filter are applied to create two EPs, the velocity EP and the loudness EP respectively. Two noise hazard metrics are proposed based on two EPs to evaluate hazardous levels caused by different types of noise. Moreover Gaussian noise and single-tone noise are simulated to evaluate performances of the proposed EPs and the noise metrics. The results show that both EPs can reflect the responses of the BM to different types of noise. For Gaussian noise there is a frequency shift between the velocity EP and the loudness EP. The results suggest that both EPs can be used for assessment of NIHL.

    Opis:
    Recognition of acoustic signals when perception is subject to interference from noise has already been extensively studied. In this study the influence of hearing protectors (HP) (plugs, muffs) and hearing loss on signal recognition is examined. Different spectrums and levels of the noise are also included. The test results are shown as the masked threshold for the signals heard and identified. In the case of normally hearing subjects a frequency-independent HP (plug) improves hearing performance, while frequency-dependent HP (muffs) tends to worsen it, especially with low-frequency noise. Hearing losses even worsen hearing performance when plugs are worn. Design suggestions are made to optimise signal recognition. Minimum signal-to-noise ratio and the use of HP are discussed.

    Opis:
    The article presents the problems of deaf and hard of hearing people in education. This topic is widely analyzed. The text describes the difficulties experienced by students at school, at various stages of learning, and the barriers experienced by deaf and hard of hearing students at higher education levels. In general, the hearing deficit entails various communication complications. The person with hearing impairment has a limited opportunity to have different experiences and what is most important in the text – hearing loss or deafness often makes it impossible to gain an optimal education. There are different methods of educating people from the non-hearing environment, depending on the degree of hearing impairment. Hearing impaired student often has difficulty understanding Polish, as it is not always their first language (their first language may be the Polish sign language). Hearing impaired students sometimes don’t understand academic texts because they have weaker poorer vocabulary due to their communication dysfunction. Another issue is the social isolation of many people with hearing impairments which often have a dilemma which environment to integrate with – with hearing or hearing impaired? Teaching staff approaches such people in different ways. Stereotypes do not help in educational progress (for example, the assumption that such students communicate only in sign language). It is important to be aware of the types of hearing loss and the different types of hearing (each hearing impaired hears differently and needs an individual approach). Finally, the article discusses the issue of education of people with hearing impairment from the category of “space”. Through “space” you can understand here the environment (school space, classes and associated architectural-acoustic barriers) as well as the language of the Deaf. The sign language is specifically designed for living space (some of the signatures must be shown in the specified movement and direction, depending on the intention of the sender).

    Opis:
    W pracy przedstawiono wyniki własnych badań nad desonoryzacją w dyslalii dotyczące otologicznych i audiologicznych uwarunkowań dobrostanu dzieci z zaburzeniami w realizacji dźwięczności fonemów obstruentalnych. Materiał badawczy pochodzi od 30 osób z desonoryzacją w wieku od 4,7 do 17,8 lat. Na podstawie specjalistycznych badań lekarskich stwierdzono, że w omawianej grupie u 80% badanych dzieci występują nieprawidłowości w obrębie błony bębenkowej dotyczące jej koloru, refleksu świetlnego, położenia i przezierności. U 53% badanych osób w audiometrii impedancyjnej uzyskano dane wskazujące na wysiękowe zapalenie ucha środkowego i/lub dysfunkcję trąbki słuchowej. Także u 53% badanych dzieci stwierdzono w audiometrii tonalnej obustronny lub jednostronny niedosłuch przewodzeniowy. Z przeprowadzonych badań wynika, że w przypadku zaburzeń desonoryzacyjnych koniecznym warunkiem logopedycznego postępowania diagnostyczno-terapeutycznego jest badanie laryngologiczno-audiologiczne i specjalistyczne leczenie.
    The research paper presents the results of own research on desonorization in dyslalia regarding otological and audiological conditions of the well-being of children with impaired performance of voicing obstruent phonemes. The research material comes from 30 people with desonorization between 4.7 and 17.8 years of age. During research it was found, basing on specialist medical examinations, that 80% of this group of the examined children had abnormalities in the tympanic membrane regarding its color, light reflex, position and translucency. The data obtained during impedance audiometry indicated that 53% of the subjects went through exudative otitis media and/or hearing tube dysfunction. The data obtained during pure tone audiometry indicated that 53% of the examined children suffered from bilateral or unilateral conductive hearing loss. The conducted research shows that in the case of desonorative disorders, a laryngological-audiological examination and specialist treatment are essential prerequisite for logopedic as well as therapeutic diagnostics.

    Objectives The objective of this study has been to test 2 spreadsheet models to compare the observed with the expected hearing loss for a Norwegian reference population. Material and Methods The prevalence rates of the Norwegian and the National Institute for Occupational Safety and Health (NIOSH) definitions of hearing outcomes were calculated in terms of sex and age, 20–64 years old, for a screened (with no occupational noise exposure) (N = 18 858) and unscreened (N = 38 333) Norwegian reference population from the Nord-Trøndelag Hearing Loss Study (NTHLS). Based on the prevalence rates, 2 different spreadsheet models were constructed in order to compare the prevalence rates of various groups of workers with the expected rates. The spreadsheets were then tested on 10 different occupational groups with varying degrees of hearing loss as compared to a reference population. Results Hearing of office workers, train drivers, conductors and teachers differed little from the screened reference values based on the Norwegian and the NIOSH criterion. The construction workers, miners, farmers and military had an impaired hearing and railway maintenance workers and bus drivers had a mildly impaired hearing. The spreadsheet models give a valid assessment of the hearing loss. Conclusions The use of spreadsheet models to compare hearing in occupational groups with that of a reference population is a simple and quick method. The results are in line with comparable hearing thresholds, and allow for significance testing. The method is believed to be useful for occupational health services in the assessment of risk of noise induced hearing loss (NIHL) and the preventive potential in groups of noise-exposed workers.

    Opis:
    Tinnitus is defi ned as a perception of sound in the absence of an external acoustic stimulus. Several factors are known to infl uence tinnitus, e.g. hearing loss, noise exposure, age, and hypertension. As only certain individuals develop tinnitus in the presence of the above risks and in approximately 50% of cases tinnitus is not attributed to any particular cause, the question arose whether this inter-individual susceptibility to tinnitus could be explained by the infl uence of genetic factors. Objectives: To test the hypothesis that genetic variability in genes of the potassium recycling pathway is associated with increased susceptibility to tinnitus. Materials and Methods: The study group consisted of 626 subjects exposed to occupational noise (128 with tinnitus and 498 without tinnitus). 99 single nucleotide polymorphisms were investigated in 10 genes involved in the potassium recycling pathway in the inner ear, previously selected as putative noise-induced hearing loss (NIHL) candidate genes. Results: Nominally signifi cant associations were obtained for 2 variants in KCNE1 (potassium voltage-gated channel, Isk-related family, member 1) and SLC12A2 (solute carrier family 12, member 2) genes. The first gene contributed to tinnitus that developed independently of hearing loss, while the second one was associated with increased susceptibility to noise-induced hearing loss. Conclusions: Present fi ndings lend support to the notion of potassium recycling pathway genes as possible risk modifi ers of tinnitus in individuals with and without hearing loss. Due to the lack of replication in other independent populations these results should be seen as suggestive.

    Opis:
    Objectives It has been shown that monitoring temporary threshold shift (TTS) after exposure to noise may have a predictive value for susceptibility of developing permanent noise-induced hearing loss. The aim of this study is to present the assumptions of the TTS predictive model after its verification in normal hearing subjects along with demonstrating the usage of this model for the purposes of public health policy. Material and Methods The existing computational predictive TTS models were adapted and validated in a group of 18 bartenders exposed to noise at the workplace. The performance of adapted TTS predictive model was assessed by receiver operating characteristic (ROC) analysis. The demonstration example of the usage of this model for estimating the risk of TTS in general unscreened population after exposure to loud music in discotheque bars or music clubs is provided. Results The adapted TTS predictive model shows a satisfactory agreement in distributions of actual and predicted TTS values and good correlations between these values in examined bartenders measured at 4 kHz, and as a mean at speech frequencies (0.5–4 kHz). An optimal cut-off level for recognizing the TTS events, ca. 75% of young people (aged ca. 35 years) may experience TTS >5 dB, while <10% may exhibit TTS of 15–18 dB. Conclusions The final TTS predictive model proposed in this study needs to be validated in larger groups of subjects exposed to noise. Actual prediction of TTS episodes in general populations may become a helpful tool in creating the hearing protection public health policy. Int J Occup Med Environ Health. 2023;36(1):125–38

    Objectives The aim of this study was to assess hearing of music students in relation to their exposure to excessive sounds. Material and Methods Standard pure-tone audiometry (PTA) was performed in 168 music students, aged 22.5±2.5 years. The control group included 67 subjects, non-music students and non-musicians, aged 22.8±3.3 years. Data on the study subjects’ musical experience, instruments in use, time of weekly practice and additional risk factors for noise-induced hearing loss (NIHL) were identified by means of a questionnaire survey. Sound pressure levels produced by various groups of instruments during solo and group playing were also measured and analyzed. The music students’ audiometric hearing threshold levels (HTLs) were compared with the theoretical predictions calculated according to the International Organization for Standardization standard ISO 1999:2013. Results It was estimated that the music students were exposed for 27.1±14.3 h/week to sounds at the A-weighted equivalent-continuous sound pressure level of 89.9±6.0 dB. There were no significant differences in HTLs between the music students and the control group in the frequency range of 4000–8000 Hz. Furthermore, in each group HTLs in the frequency range 1000–8000 Hz did not exceed 20 dB HL in 83% of the examined ears. Nevertheless, high frequency notched audiograms typical of the noise-induced hearing loss were found in 13.4% and 9% of the musicians and non-musicians, respectively. The odds ratio (OR) of notching in the music students increased significantly along with higher sound pressure levels (OR = 1.07, 95% confidence interval (CI): 1.014–1.13, p < 0.05). The students’ HTLs were worse (higher) than those of a highly screened non-noise-exposed population. Moreover, their hearing loss was less severe than that expected from sound exposure for frequencies of 3000 Hz and 4000 Hz, and it was more severe in the case of frequency of 6000 Hz. Conclusions The results confirm the need for further studies and development of a hearing conservation program for music students. Int J Occup Med Environ Health 2017;30(1):55–75

    ObjectivesThe aim of the study was to evaluate the hearing status of operators of low-frequency ultrasonic devices compared to employees exposed to audible noise at a similar A-weighted sound pressure level (SPL) but without ultrasonic components.Material and MethodsStandard pure-tone audiometry, extended high-frequency audiometry (EHFA), transient-evoked otoacoustic emissions (TEOAE), and distortion-product otoacoustic emissions (DPOAE), as well as questionnaire surveys were conducted among 148 subjects, aged 43.1±10.8 years, working as ultrasonic device operators for 18.7±10.6 years. Their exposure to noise within the ultrasonic and audible frequency range was also evaluated. The control group comprised 168 workers, adjusted according to gender, age (±2 years), tenure (±2 years), and the 8-hour daily noise exposure level (LEX,8h) of ±2 dB.ResultsThe ultrasonic device operators and the control group were exposed to audible noise at LEX,8h of 80.8±3.9 dB and 79.1±3.4, respectively. The Polish maximum admissible intensity (MAI) values for audible noise were exceeded in 16.8% of the ultrasonic device operators, while 91.2% of them were exposed to ultrasonic noise at SPL>MAI values. There were no significant differences between the groups in terms of the hearing threshold levels (HTLs) up to 3 kHz, while the ultrasonic device operators exhibited significantly higher (worse) HTLs, as compared to the control group, in the range of 4–14 kHz. The results of the DPOAE and TEOAE testing also indicated worse hearing among the ultrasonic device operators. However, the differences between the groups were more pronounced in the case of EHFA and DPOAEs.ConclusionsThe outcomes of all hearing tests consistently indicated worse hearing among the ultrasonic device operators as compared to the control group. Both EHFA and DPOAE seem to be useful tools for recognizing early signs of hearing loss among ultrasonic device operators.

    In this paper, we present a case report of a 26-year-old patient who had been experiencing isolated unilateral tinni-tus for 2 months. Audiologic examinations, such as pure tone, speech and impedance audiometry, ABR and vestibular evoked myogenic potential (VEMP) showed no abnormalities. The videonystagmography (VNG) and computerized dynamic posturography (CDP) also showed no pathology. Magnetic Resonance Imaging (MRI) was the only test that confirmed the presence of the vestibular schwannoma in this patient. Conclusions: MRI should be considered in pa-tients suspected of having a vestibular schwannoma with unilateral tinnitus as the only symptom, despite normal au-diological test results (with no retrocochlear findings).

    Opis:
    The aim of this work was to study the effect of middle ear disorder on round window (RW) stimulation, so as to provide references for the optimal design of RW stimulation type middle ear implants (MEIs). Methods: A human ear finite-element model was built by reverse engineering technique based on micro-computed tomography scanning images of human temporal bone, and was validated by three sets of comparisons with experimental data. Then, based on this model, typical disorders in otosclerosis and otitis media were simulated. Finally, their influences on the RW stimulation were analyzed by comparison of the displacements of the basilar membrane. Results: For the otosclerosis, the stapedial abnormal bone growth severely deteriorated the equivalent sound pressure of the RW stimulation at higher frequencies, while the hardening of ligaments and tendons prominently decreased the RW stimulation at lower frequencies. Besides, among the hardening of the studied tissues, the influence of the stapedial annular ligament’s hardening was much more significant. For the otitis media, the round window membrane (RWM)’s thickening mainly decreased the RW stimulation’s performance at lower frequencies. When the elastic modulus’ reduction of the RWM was considered at the same time especially for the acute otitis media, it would raise the lower-frequency performance of the RW stimulation. Conclusions: The influence of the middle ear disorder on the RW stimulation is considerable and variable, it should be considered during the design of the RW stimulation type MEIs.

    Opis:
    Noise measurements and questionnaire inquiries were carried out for 124 workers of a rolling stock plant to develop a hearing conservation program. On the basis of that data, the risk of noise-induced hearing loss (NIHL) was evaluated. Additionally, the workers’ hearing ability was assessed with the (modified) Amsterdam inventory for auditory disability and handicap, (m)AIADH. The workers had been exposed to noise at A-weighted daily noise exposure levels of 74–110 dB for 1-40 years. Almost one third of the workers complained of hearing impairment and the (m)AIADH results showed some hearing difficulties in over half of them. The estimated risk of hearing loss over 25 dB in the frequency range of 3-6 kHz was 41–50% when the standard method of predicting NIHL specified in Standard No. ISO 1999:1990 was used. This risk increased to 50-67% when noise impulsiveness, coexposure to organic solvents, elevated blood pressure and smoking were included in calculations.

    Opis:
    The study aimed at the retrospective analysis of the patients with disorders of the balance system and/or hearing organ in the course of systemic diseases. Among 1,208 patients (727 women and 481 men) who were hospitalised in the Department of Otolaryngology and Laryngological Oncology with Audiological and Phoniatric Units at Military Medical Academy University Clinical Hospital in Lodz within the years 2009-2010 and revealed disorders of the balance system, tinnitus and/or hearing impairment, 300 case histories were chosen randomly, including 182 women aged 20-85 and 118 men aged 17-90 Each patient underwent a detailed interview, otorhinolaryngological and otoneurological examination, tonal, verbal and impedance audiometry, suprathreshold audiometric tests (SISI, TDT), tinnitus intensity and frequency evaluation, auditory brainstem response (ABR), videonystagmography (pendulum tracking, positional nystagmus described in five positions by Nylen, evaluation of nystagmus provoked by a thermal stimulation in Fitzgerald-Hallpike bicaloric testing), additionalimaging studies of the head and/or cervical spine, including cranial arteries ultrasonography and routine laboratory tests. Among all the systemic diseases the diseases of the balance system were most common in both sexes (women – 41.76%, men – 44.91%, 43% altogether). Endocrine diseases were the second most often disorders (20.67%) and occurred more often in women (28.02%) than in men (9.32%). Neurological diseases were present in 8.33% of the cases (women – 10.44%, men – 5.08%). Malignant neoplasms were found in 4.3% of the cases, whereas autoimmune diseases occurred highly infrequently (2.33%). A number of the systemic diseases was accompanied by concomitant disorders of the balance system and hearing organ. Every physician, particularly GP, should take into consideration possible vertigo, tinnitus and hearing deterioration in the course of the systemic diseases.
    Celem pracy była retrospektywna analiza pacjentów z zaburzeniami układu równowagi i/lub narządu słuchu w przebiegu chorób ogólnoustrojowych. Spośród 1208 chorych, w tym 727 kobiet i 481 mężczyzn, hospitalizowanych w latach 2009-2010 w Klinice Otolaryngologii i Onkologii Laryngologicznej z Zespołem Pracowni Audiologicznych i Foniatrycznych USK im. WAM w Łodzi, u których rozpoznano zaburzenia układu równowagi, szumy uszne i/lub uszkodzenie słuchu, losowo wybrano 300 przypadków – 182 kobiety w wieku 20-85 lat i 118 mężczyzn w wieku 17-90 lat. U każdego pacjenta zebrano szczegółowo wywiad, wykonano badania otorynolaryngologiczne i otoneurologiczne, audiometrie tonalną, słowną i impedancyjną, próby nadprogowe (SISI, TDT), ocenę natężenia i częstotliwości szumu, słuchowe potencjały wywołane pnia mózgu (ABR), badanie wideonystagmograficzne (ocena śledzenia ciągłego i kaskadowego, oczopląsu wywołanego bodźcem położeniowym, określanym w pięciu pozycjach wg Nylena, ocena oczopląsu wywołanego bodźcem termicznym w teście dwukalorycznym wg Fitzgeralda-Hallpike’a) oraz dodatkowe badania obrazowe głowy i/lub szyjnego odcinka kręgosłupa, w tym badanie USG tętnic doczaszkowych, a także rutynowe badania laboratoryjne. Spośród chorób ogólnoustrojowych najczęściej u obu płci występowały choroby układu krążenia (kobiety – 41,76%, mężczyźni – 44,91%, łącznie 43%). Choroby endokrynologiczne stanowiły drugą co do częstości występowania grupę (20,67%) i częściej występowały u kobiet (28,02%) niż u mężczyzn (9,32%). Choroby neurologiczne stwierdzono w 8,33% przypadków, w tym u 10,44% kobiet i u 5,08% mężczyzn, a nowotwory złośliwe w 4,3% przypadków. Najrzadziej obserwowano choroby autoimmunologiczne – 2,33%. Wielu chorobom ogólnoustrojowym towarzyszyły jednoczesne zaburzenia układu równowagi i narządu słuchu. Każdy lekarz, a szczególnie lekarz podstawowej opieki zdrowotnej powinien brać pod uwagę możliwość wystąpienia zawrotów głowy, szumów i pogorszenia słuchu w przebiegu chorób ogólnoustrojowych.

    Opis:
    The aim of this study was to evaluate the hearing status in young adults using portable audio players (PAPs) in relation to their listening habits. The study included 58 subjects, aged 22.8±2.8 years, non-occupationally exposed to noise. Questionnaire inquiry aimed at collecting personal data, the information on PAPs usage habits, self-assessment of hearing status and identification of risk factors for noise-induced hearing loss (NIHL) were performed in study subjects. Hearing tests included pure-tone audiometry (PTA) and transient-evoked optoacoustic emission (TEOAE). All subjects were PAPs users. Depending on listening habits they were divided into the subgroups of “frequent” users (>1 h/day) and “non-frequent” users (≤1 h/day). There were no significant differences between subgroups in prevalence of NIHL risk factors and self-assessment of hearing status. However, frequent users more often complained of tinnitus and hyperacusis. Majority (81.9 %) of participants had normal hearing. Nevertheless, 6.9 % of audiograms showed high-frequency notches typical for NIHL. Both, the PTA and TEOAE indicated worse hearing in non-frequent users compared to frequent users. No significant differences in prevalence of high-frequency notches between subgroups were noted. The outcomes do not support some previous studies results that the excessive exposure to music listened through PAPs might result in accelerating of development of NIHL loss in young adults.

    Opis:
    W 2019 r. choroba spowodowana SARS-CoV-2 – COVID-19 – wywołała wciąż trwającą pandemię. Do najczęstszych objawów klinicznych zakażenia SARS-CoV-2 należą: gorączka, suchy kaszel, zmęczenie, bóle mięśniowe, problemy z oddychaniem, utrata węchu i/lub smaku. Inne dolegliwości, w tym ze strony narządu słuchu i równowagi, np. niedosłuch, szumy uszne czy zawroty głowy, zgłaszane są przez chorych rzadziej. Jako pierwsze objawy tej infekcji bywają wskazywane sporadycznie. Chcąc odpowiedzieć na pytanie, czy SARS-CoV-2 może być przyczyną uszkodzenia słuchu i równowagi, autorzy dokonali przeglądu piśmiennictwa z lat 2019–2020 w bazach EMBASE i PubMed, wpisując hasła: „hearing loss”, „COVID-19”, „corona virus”, „sensorineural hearing loss”, „vertigo”, „dizziness”. Do opracowania zakwalifikowano 9 prac dotyczących potencjalnego związku uszkodzenia słuchu z SARS-CoV-2 oraz 4 prace omawiające ewentualne zaburzenia równowagi na skutek infekcji SARS-CoV-2. Wyniki analizy wskazują na możliwe istnienie związku pomiędzy COVID-19 a uszkodzeniem słuchu przy jednoczesnym braku dowodów na istnienie podobnej relacji między przebytą infekcją tym wirusem a układem równowagi. O tej prawdopodobnej zależności – zwłaszcza o możliwości wystąpienia nagłego niedosłuchu czuciowo-nerwowego jako pierwszego objawu COVID-19 – powinni szczególnie pamiętać lekarze szpitalnych izb przyjęć, otolaryngolodzy i audiolodzy. Dotyczy to również lekarzy innych specjalności. Autorzy wskazują potrzebę prowadzenia dalszych, intensywnych, wielopłaszczyznowych badań nad tym zagadnieniem. Med. Pr. 2021;72(3):321–325
    In 2019, COVID-19, the disease caused by the SARS-CoV-2 virus, evolved into a pandemic which is still going on. The basic clinical symptoms of the SARS-CoV-2 infection are: fever, dry cough, fatigue, muscle pain, respiratory problems, and the loss of smell or taste. Other symptoms, including those related to hearing and balance organs (hearing loss, tinnitus, dizziness), are reported less frequently by patients. They are especially rarely reported as the first symptoms of this infection. In order to answer the question of whether SARS-CoV-2 can cause hearing and balance damage, the authors reviewed the literature sources from 2019–2020 included in EMBASE and PubMed, entering the following words: “hearing loss,” “COVID-19,” “coronavirus,” “sensorineural hearing loss,” “vertigo,” and “dizziness.” Ultimately, 9 studies on the possible relationship between hearing impairment and SARS-CoV-2, and 4 studies on the possible relationship between damage to the balance and SARS-CoV-2, were qualified for the study. The results of the analysis suggest a possible relationship between COVID-19 and hearing loss, with no evidence of a similar relationship between this virus and the balance system. The possible existence of such a relationship should be especially remembered by hospital emergency room doctors, otolaryngologists and audiologists, especially as regards the possibility of a sudden sensironeural hearing loss as the first symptom of COVID-19. This also applies to doctors of other specialties. The authors indicate the need for further, intensive and multifaceted research on this issue. Med Pr. 2021;72(3):321–5

    Objective: The aim of this study is to present a methodology of vestibular evoked myogenic potentials registered from sternocleidomastoid muscle (SCM) using skull tap stimulation (Tap-cVEMP) in a patient with cerebellopontine angle tumor (CPAT). Material and methods: A 23-year-old female with CPAT. The methodology of Tap-cVEMP is introduced. The results of VEMP is confronted with surgical information about the tumor. Results: The results of AC-cVEMP and Tap-cVEMP revealed the inferior vestibular nerve bundle to be affected by the tumor with intact superior bundle. Information obtained from VEMP was confirmed during surgery. Conclusion: Skull Tap Vestibular Evoked Myogenic Potentials (Tap-cVEMP) may be the useful method in the diagnostics of CPAT. AC-cVEMP and Tap-cVEMP may be helpful to evaluate the functional integrity of both vestibular nerve bundles providing the information about their involvement in the pathological process.

    Opis:
    The success of certain industrial activities bring both benefits and negative effects such as pollution, occupational diseases, exposure of workers and residents of neighboring areas and high risk in case of technological failure. An undesirable effect of industrial activity which may be considered a threat to workers and residents in the immediate vicinity of industrial sites is the noise. Due to the presence of technology in all activities, is a major problem considering its nature and harmful repercussions on health. Hearing loss and deafness caused by occupational exposure to noise at work are the most common occupational diseases that occur in the European Union. The development of modern technology by increasing the power and speed of the technical equipment, contributed to diversify and increase the number of sources of noise and vibration, and thus to increase the number of people exposed. This paper analyzes the effect of noise from industrial equipment and health risks.
    Sukces w działalności przemysłowych przynosi zarówno korzyści, jak i negatywne zjawiska, takie jak zanieczyszczenie, choroby zawodowe, ekspozycja pracowników bezpośrednich oraz sąsiedztwa zakładów przemysłowych na ryzyko związane z awariami, katastrofami technologicznymi. Niepożądanym efektem działalności przemysłowej, który może być uznany za zagrożenie dla pracowników oraz otoczenia zakładów jest hałas. Z uwagi na obecność technologii w większości działań, głównym problemem wynikającym z natury hałasu są jego negatywne skutki zdrowotne. Ubytek słuchu czy głuchota spowodowane ekspozycją na hałas w miejscu pracy są najczęściej występującymi chorobami zawodowymi w Unii Europejskiej. Rozwój nowoczesnej technologii poprzez wzrost wydajności i szybkości działania wyposażenia wpływa na dywersyfikację i wzrost liczby źródeł hałasu i wibracji a tym samym oddziałuje na większą liczbę osób. W artykule przedstawiono oddziaływanie hałasu pochodzącego z maszyn oraz zagrożenia zdrowotne.

    Opis:
    W związku z wykazanymi właściwościami ototoksycznymi rozpuszczalników organicznych w Dyrektywie 2003/10/WE Parlamentu Europejskiego i Rady Unii Europejskiej zalecono, aby w szacowaniu ryzyka zawodowego uszkodzenia słuchu brać pod uwagę interakcję skutków działania hałasu i rozpuszczalników na narząd słuchu. Uwzględniając brak sprecyzowanych do tej pory zaleceń profilaktycznych, niniejsze opracowanie ma na celu dostarczenie lekarzowi wskazówek w zakresie prowadzenia badań słuchu u pracowników eksponowanych na te zagrożenia. W tej pracy omówiono biologiczne skutki działania hałasu i rozpuszczalników organicznych na narząd słuchu oraz aktualne możliwości szacowania ryzyka uszkodzenia słuchu w przypadku izolowanego narażenia na rozpuszczalniki oraz ich współdziałania z hałasem. Przedstawiono zakres badania lekarskiego oraz znaczenie poszczególnych badań słuchu, w tym audiometrii tonalnej, otoemisji akustycznych, audiometrii impedancyjnej, słuchowych potencjałów wywołanych pnia mózgu, audiometrii mowy w ciszy, audiometrii mowy w szumie oraz dychotycznego testu cyfrowego w diagnostyce uszkodzeń spowodowanych przez rozpuszczalniki organiczne. Opracowano algorytm przeprowadzania badań słuchu w przypadku narażenia na rozpuszczalniki organiczne oraz hałas i rozpuszczalniki w zależności od poziomu narażenia. Wskazano konieczność corocznych badań audiometrycznych u wszystkich pracowników narażonych na rozpuszczalniki organiczne w przypadku przekroczenia ich stężeń w powietrzu, bezpiecznych dla narządu słuchu, niezależnie od współwystępowania narażenia na hałas. U osób narażonych na hałas i rozpuszczalniki organiczne okresowa audiometria tonalna powinna być obowiązkowo wykonywana już przy przekroczeniu wartości dolnego progu działania dla hałasu określonego w Dyrektywie 2003/10/WE, tj. LEX,8h = 80 dB. Biorąc pod uwagę działanie uszkadzające rozpuszczalników organicznych na część ośrodkową narządu słuchu, dodatkowo do audiometrii tonalnej zalecane jest badanie audiometrii mowy (optymalnie audiometrii mowy w szumie). Wprowadzenie profilaktycznych badań słuchu u pracowników narażonych na rozpuszczalniki organiczne oraz rozszerzenie wskazań i zakresu badań słuchu u osób eksponowanych łącznie na hałas i rozpuszczalniki jest warunkiem skutecznej profilaktyki uszkodzeń słuchu w tych grupach zawodowych.
    Robust evidence confirms that occupational exposures to organic solvents are ototoxic and can aggravate the effects of noise on the auditory organ. Accordingly, Directive 2003/10/EC of the European Parliament and of the Council recommends that in assessing the risk of occupational hearing loss, the interaction of noise and organic solvents to hearing should be taken into account. Given that no prophylactic recommendations have been established to date, this study is intended to provide physicians with guidance in conducting audiometric tests in workers exposed to noise and organic solvents. The paper discusses the biological effects of noise and organic solvents on the auditory organ and current possibilities of estimating the risk of hearing loss due to isolated exposures to solvents, as well as combined exposures to these chemicals and noise. The scope of medical examination and the significance of individual hearing tests, such as pure-tone audiometry, impedance audiometry, auditory brainstem responses, speech in quiet and speech in noise audiometry, and dichotic digit test, in the diagnostics of solvent-induced hearing loss are presented. An algorithm for conducting hearing tests in workers exposed to organic solvents, and co-exposed to noise and organic solvents, has been proposed depending on the concentration of solvents and noise level. Shown also is the necessity to perform annual audiometric testing in all workers exposed to organic solvents whose concentration in the air exceeds values safe for hearing. In workers exposed to noise and organic solvents, audiometric examinations should be mandatory in all subjects in whom the level of noise exceeds the lower action level defined by Directive 2003/10/EC, which is LEX,8h = 80 dB. Taking into account the detrimental effects of organic solvents to central auditory pathways, in addition to pure-tone audiometry, speech audiometry (preferentially speech in noise) should be included. The introduction of preventive audiometric tests in workers exposed to organic solvents, along with an extension of indications and the scope of hearing tests in workers co-exposed to noise and solvents, is a prerequisite for effective prevention of occupational hearing loss in these professional groups.

    Objectives The objective of this study was to assess the hearing of employees using communication headsets with regard to their exposure to noise. Material and Methods The study group comprised 213 employees, including 21 workers of the furniture industry, 15 court transcribers and 177 call center operators, aged 19–55 years, working with headsets for a period of up to 25 years. All the participants underwent a standard puretone audiometry, extended high-frequency audiometry (EHFA) as well as transient-evoked otoacoustic emissions (TEOAEs) and distortion-product otoacoustic emissions (DPOAEs). Noise exposure from headsets was evaluated using the microphone in a real ear technique according to PN-EN ISO 11904-1:2008. Results Personal daily noise exposure levels ranged 57–96 dB and exceeded 85 dB only in 1.4% of the call center operators. Forty-two percent of the participants had bilateral normal hearing in the standard frequency range of 250–8000 Hz, and 33% in the extended highfrequency range of 9–16 kHz. It was found that DPOAEs were present bilaterally in 59% of the participants. Reproducibility of TEOAE at >70% and signal-to-noise ratio at >6 was exhibited by 42% and 17% of them, respectively. The 3 subgroups of workers differed in age, gender, noise exposure and type of headsets in use. However, after adjusting for age and gender, significant differences between these subgroups in terms of hearing were mostly visible in EHFA. A significant impact of age, gender, daily noise exposure level and current job tenure on hearing tests results was also noted among the call center operators and the transcribers. The most pronounced were the effects of age and gender, whereas the impact of the daily noise exposure level was less evident. Conclusions It seems that EHFA is useful for recognizing early signs of noise-induced hearing loss among communication headset users. However, further studies are needed before any firm conclusions concerning the risk of hearing impairment due to the use of such devices can be drawn.

    Opis:
    The paper presents the development of a method for assessing auditory perception and the effectiveness of applying hearing aids for hard-of-hearing people during short-term (up to 7 days) and longer-term (up to 3 months) use. The method consists of a survey based on the APHAB questionnaire. Additional criteria such as the degree of hearing loss, technological level of hearing aids used, as well as the user experience are taken into consideration. A web-based application is developed, allowing answering the survey questions from any computer with Internet access. The results of the benefit obtained from the use of hearing aids in various acoustic environments, taking into account the time of their use, are presented and compared to the earlier outcomes. The research results show that in the first period of use of hearing aids, speech perception improves, especially in noisy environments. The perception of unpleasant sounds also increases, which may lead to deterioration of hearing aid acceptance by their users.

    Opis:
    Children are at risk of developing hearing problems due to their exposure to high sound pressure levels for excessive amounts of time. The aim of this project was to establish the relationship between sound levels in the most hazardous fields and their effect on children’s sense of hearing. Measuring sound pressure levels in schools, analysing earphone and headphone usage and comparing them to audiometry results enabled basic dependencies to be found. Some of the examined children fall outside the safe exposure times to certain sound pressure levels (according to WHO directives). The results analysed in frequency bands show that there is a clear correlation between a shift in hearing threshold and intensity levels in music. Noise during lessons is not very high, but the noise during breaks and of bell rings can influence children’s’ hearing to a certain extent. Due to improper usage of earphones and headphones, the young people we examined may develop hearing loss at an early age.

    Opis:
    Noise induced hearing loss (NIHL) is a serious occupational related health problem worldwide. The A-wave impulse noise could cause severe hearing loss, and characteristics of such kind of impulse noise in the joint time-frequency (T-F) domain are critical for evaluation of auditory hazard level. This study focuses on the analysis of A-wave impulse noise in the T-F domain using continual wavelet transforms. Three different wavelets, referring to Morlet, Mexican hat, and Meyer wavelets, were investigated and compared based on theoretical analysis and applications to experimental generated A-wave impulse noise signals. The underlying theory of continuous wavelet transform was given and the temporal and spectral resolutions were theoretically analyzed. The main results showed that the Mexican hat wavelet demonstrated significant advantages over the Morlet and Meyer wavelets for the characterization and analysis of the A-wave impulse noise. The results of this study provide useful information for applying wavelet transform on signal processing of the A-wave impulse noise.

    Wstęp Celem pracy była ocena narażenia na hałas i ryzyka uszkodzenia słuchu spowodowanego hałasem wśród użytkowników słuchawkowych zestawów komunikacyjnych lub słuchawek. Materiał i metody W grupie 74 pracowników (wiek: 31,8±7,3 roku), w tym personelu lotnictwa wojskowego (N = 12), transkrybentów (N = 18) i telemarketerów (N = 44), przeprowadzono pomiary hałasu i badania kwestionariuszowe. Poziomy dźwięku emitowanego przez słuchawkowe zestawy komunikacyjne (lub słuchawki) zmierzono z zastosowaniem techniki microphone in the real ear (MIRE) i techniki sztucznego ucha, odpowiednio, według norm PN-EN ISO 11904-1:2008 i CSA Z107.56-13. Ryzyko uszkodzenia słuchu wywołanego hałasem oszacowano zgodnie z wytycznymi normy PN-ISO 1999:2000. Wyniki Mierzone pod słuchawkami i słuchawkowymi zestawami komunikacyjnymi z zastosowaniem technik MIRE i sztucznego ucha wartości równoważnego poziomu dźwięku A (odpowiadającego warunkom pola rozproszonego) wynosiły, odpowiednio, 67–86 dB (10–90 percentyl) i 68–89 dB (10–90 percentyl). Badani pracownicy używali tych urządzeń średnio przez 1,5–8 godz. dziennie (10–90 percentyl). Ekspozycja na takie poziomy dźwięku przez 40 lat pracy wiąże się z ryzykiem uszkodzenia słuchu (średni próg słuchu dla częstotliwości 2, 3 i 4 kHz > 25 dB) sięgającym 10–12% (technika MIRE) lub 19–22% (technika sztucznego ucha). Wartości indywidualnego dziennego poziomu ekspozycji na hałas w badanej grupie wynosiły 71–85 dB (10–90 percentyl). Część pracowników skarżyła się na problemy z rozumieniem mowy w hałaśliwym otoczeniu (28,4%) i słyszeniem szeptu (16,2%) oraz zauważyła przejściowe skutki słuchowe po pracy z zastosowaniem słuchawkowych zestawów komunikacyjnych lub słuchawek (16,2–25,7%). Wnioski Wskazane jest objęcie użytkowników słuchawkowych zestawów komunikacyjnych i słuchawek programem ochrony słuchu oraz kontynuowanie badań wśród pracowników innych branż. Med. Pr. 2019;70(1):27–52
    Background The aim of the study was to assess the noise exposure and risk of noise-induced hearing loss (NIHL) among users of communication headsets (CHs) or headphones. Material and Methods Noise measurements and questionnaire surveys were carried out in 74 workers (aged: 31.8±7.3 years), including military aviation personnel (N = 12), transcribers (N = 18) and call center operators (N = 44). Sound pressure levels (SPLs) emitted by CHs (or headphones) were determined using the microphone in the real ear (MIRE) technique and artificial ear techniques according to PN-EN ISO 11904-1:2008 and CSA Z107.56-13, respectively. The risk of NIHL was evaluated in accordance with PN-ISO 1999:2000. Results The diffused-field-related A-weighted equivalent-continuous SPLs measured under CHs (or headphones) using the MIRE and artificial ear techniques reached values of 67–86 dB (10–90th percentile) and 68–89 dB (10–90th percentile), respectively. The study subjects used these devices 1.5–8 h (10–90th percentile) per day. Exposure to such noise levels for 40 years of employment causes the risk of hearing impairment (mean hearing threshold level for 2, 3 and 4 kHz > 25 dB) up to 10–12% (MIRE technique) or 19–22% (artificial ear technique). Individual daily noise exposure levels in study group varied 71–85 dB (10–90th percentile). A number of workers complained of problems with understanding speech in noisy environment (28.4%) and hearing whisper (16.2%) and experienced post-work temporary hearing symptoms (16.2–25.7%) as well. Conclusions The users of CHs and headphones should be included in the hearing conservation program. Further studies are also needed among employees of other industries. Med Pr. 2019;70(1):27–52

    Opis:
    Dystrofia twarzowo-łopatkowo-ramieniowa (FSHD) to trzecia co do częstości występowania dystrofia mięśniowa, dziedziczona autosomalnie dominująco. Pierwsze objawy zazwyczaj manifestują się w drugiej dekadzie życia, a bardzo wczesny początek (u dzieci przed 10. rokiem życia) wiąże się z ciężkim przebiegiem choroby, szybszym postępem niesprawności oraz większym ryzykiem powikłań. Praca ma na celu przedstawienie najważniejszych zagadnień dotyczących FSHD z punktu widzenia praktyki klinicznej – objawów, diagnostyki oraz opcji terapeutycznych, z uwzględnieniem wyników najnowszych badań, aktualnego piśmiennictwa oraz wytycznych opublikowanych przez Amerykańskie Towarzystwo Neurologiczne w 2015 roku.
    Facio-scapulo-humeral dystrophy (FSHD) is a third most common muscular dystrophy of autosominal dominant pattern of inheritance. The onset of symptoms usually takes place in the second decade of life, whereas very early disease manifestation (in children below 10- year old) is linked to more severe clinical picture with quicker disability progression and higher risk of complications. This paper aims to present the most relevant issues in clinical practice concerning FSHD – symptoms, diagnostic process and therapeutic options, based on the latest publications, including evidence-based guidelines published by AAN in 2015.

    Wstęp Celem pracy była analiza stanu słuchu pracowników zakładu meblarskiego z uwzględnieniem ich narażenia zawodowego na hałas i występowania dodatkowych czynników ryzyka uszkodzenia słuchu spowodowanego hałasem. Materiał i metody W grupie 50 mężczyzn w wieku 20–57 lat, zatrudnionych bezpośrednio przy produkcji mebli, przeprowadzono pomiary hałasu, badania kwestionariuszowe i ocenę stanu słuchu z zastosowaniem audiometrii tonalnej. Rzeczywiste progi słuchu pracowników porównano z progami przewidywanymi, wyznaczonymi według normy PN-ISO 1999:2000 na podstawie ich wieku, płci i narażenia na hałas. Wyniki Badane osoby pracowały przez 3–14 lat w warunkach narażenia na hałas o jego dziennym poziomie ekspozycji 82,7–94,8 dB (średnia: 90,9 dB). U wszystkich osób średni próg słuchu dla częstotliwości 500 Hz, 1000 Hz, 2000 Hz i 4000 Hz nie przekraczał 25 dB, ale w przypadku 11% audiogramów zaobserwowano załamki wysokoczęstotliwościowe, typowe dla działania hałasu. Rzeczywiste progi słuchu pracowników w zakresie częstotliwości 3000–6000 Hz były zbliżone do przewidywanych według PN-ISO 1999:2000. Stwierdzono istotnie statystyczne różnice między progami słuchu w podgrupach osób z wyższym (> 78 mm Hg) i niższym (≤ 78 mm Hg) ciśnieniem rozkurczowym krwi, palących papierosy i niepalących oraz pracujących bez kontaktu lub w kontakcie z rozpuszczalnikami organicznymi. U osób z ww. dodatkowymi czynnikami ryzyka obserwowano większe ubytki słuchu. Wnioski Wyniki badań potwierdzają, że podczas szacowania ryzyka uszkodzenia słuchu spowodowanego hałasem i opracowywania programów ochrony słuchu pracowników konieczne jest uwzględnianie dodatkowych (poza hałasem) czynników ryzyka, w tym palenia papierosów, podwyższonego ciśnienia tętniczego krwi i równoczesnej ekspozycji na rozpuszczalniki organiczne.

    Background The aim of the study was to analyze the hearing status of employees of a furniture factory with respect to their exposure to noise and the presence of additional risk factors of noise-induced hearing loss (NIHL). Material and Methods Noise measurements, questionnaire survey and assessment of hearing, using pure tone audiometry, were carried out in 50 male workers, aged 20–57 years, directly employed in the manufacture of furniture. The actual workers’ hearing threshold levels (HTLs) were compared with the predictions calculated according to PN-ISO 1999:2000 based on age, gender and noise exposure. Results Workers under study were exposed to noise at daily noise exposure levels of 82.7–94.8 dB (mean: 90.9 dB) for a period of 3–14 years. In all subjects, mean HTL at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz did not exceed 25 dB. Nevertheless, high frequency notches were found in 11% of audiograms. The actual workers’ HTLs at 3000–6000 Hz were similar to those predicted using PN-ISO 1999:2000. There were statistical significant differences between HTLs in subgroups of people with higher (> 78 mm Hg) and lower (≤ 78 mm Hg) diastolic blood pressure, smokers and non-smokers, and those working with organic solvents. Hearing loss was more evident in subjects affected by the additional risk factors specified above. Conclusions The results confirm the need to consider, in addition to noise, also some other NIHL risk factors, such as tobacco smoking, elevated blood pressure, and co-exposure to organic solvents when estimating the risk of NIHL and developing the hearing conservation programs for workers.

    Objective: The objective of the study was to present the methodology and interpretation of the results of distortion-product otoacoustic emission phase shift (Shift-DPOAE) measurements in healthy subjects and patients with Meniere’s disease in remission or during the attack. Material and methods: Shift-DPOAE measurements were performed in two healthy subjects with no otological or neurological problems as well as in six patients diagnosed with Meniere’s disease. Results obtained from all eight subjects are presented. Detailed otoscopy, impedance audiometry, pure tone audiometry, DPOAE, and Shift-DPOAE tests were performed in all subjects. Results: Normal results of Shift-DPOAE measurements obtained from two healthy subjects as well as normal (two subjects) and abnormal (four subjects) Shift-DPOAE results obtained from patients with Meniere’s disease are presented in order to thoroughly discuss the methodology and interpretation of Shift-DPOAE measurements. Conclusions: Shift-OAE is a promising diagnostic tool with a great clinical potential for diagnostics and monitoring of Meniere’s disease in patients whose hearing has not yet been damaged. The test is completely non-invasive and can be carried out immediately after the onset of disease attack with symptoms still present at the time of the test; in addition, the procedure takes just several minutes.
    Cel: Przedstawienie metodologii badania oraz prezentacja wyników przesunięcia w fazie otoemisji akustycznych produktów zniekształceń nieliniowych ślimaka (Shift-DPOAE), wykonanego u osób zdrowych i z potwierdzoną chorobą Meniere’a w fazie remisji oraz w ostrej fazie choroby w czasie ataku. Materiał i metody: Badanie Shift-DPOAE zostało wykonane u dwóch osób z prawidłowym słuchem i bez żadnych problemów otologicznych i neurologicznych (osoby zdrowe) oraz u sześciu z klinicznie zdiagnozowaną chorobą Meniere’a. W sumie w pracy prezentowano wyniki uzyskane u ośmiu osób. U wszystkich badanych wykonano następujące badania: dokładną otoskopię, audiometrię impedancyjną, audiometrię tonalną, tradycyjne badanie DPOAE oraz Shift-DPOAE. Wyniki: Zaprezentowano i omówiono prawidłowe wyniki Shift-DPOAE uzyskane u dwóch osób zdrowych oraz wyniki prawidłowe (dwie osoby) i nieprawidłowe (cztery osoby) uzyskane u pacjentów z chorobą Meniere’a, w celu dokładnego omówienia metodologii i interpretacji badania Shift-DPOAE. Wnioski: Shift-OAE to obiecujące badanie z dużym potencjałem klinicznym w diagnostyce i monitorowaniu choroby Meniere’a u pacjentów, u których słuch nie został jeszcze uszkodzony. Jest ono całkowicie nieinwazyjne, może być przeprowadzone zaraz po ataku choroby w trakcie trwania objawów, a jego wykonanie zajmuje zaledwie klika minut.

Opis umiejętności opracowany został z wykorzystaniem Karty Badania Surdologopedycznego oraz Karty Oceny Zachowań Komunikacyjnych Dziecka z Uszkodzonym Słuchem. Narzędzia te umożliwiły dokonanie szczegółowej charakterystyki umiejętności dziecka w zakresie porozumiewania się fonicznego we wszystkich podsystemach języka: fonologicznym, leksykalnym oraz gramatycznym: morfologicznym i składniowym. Ocenie poddano również zachowania gestowo-mimiczne dziecka pełniące funkcję komunikacyjną. Omówione zostały także możliwości audiologiczne dziecka ze szczególnym wskazaniem na korzyści, jakie odnosi z obuusznej implantacji i intensywnej pracy surdologopedycznej. Wyniki badań pozwoliły stwierdzić, że mowa jest preferowanym sposobem komunikowania się badanej dziewczynki. Osiągnęła ona bardzo wysokie umiejętności w zakresie komunikacji fonicznej, zbliżone do poziomu prezentowanego przez słyszących rówieśników. Porozumiewanie się gestowo-mimiczne pełni funkcję pomocniczą. Bazuje na gestykulacji naturalnej, choć dziecko miało epizod nauki podstaw języka migowego. Analiza historii rozwoju mowy dziecka pozwala dostrzec silną zależność między czasem implantacji a przyspieszeniem dynamiki rozwoju jego mowy.
    This article is a case study of a five-year-old girl infected with cytomegalovirus, with profound prelingual sensorineural hearing loss, bilaterally implanted. The aim of the article is to describe research on the child’s current development and current communication skills in the context of early diagnosis, early binaural implantation and systematic speech therapy of the examined child. The description of the skills was developed using the Speech and Language Therapy Examination Card and the Communication Behavior Assessment Card for a Hearing Impaired Child. These tools enabled a detailed characterization of the child’s phonic communication skills in all language subsystems: phonological, lexical and grammatical: morphological and syntactic. The child’s gestural and facial behavior serving a communicative function was also assessed. The child’s audiological capabilities were also discussed, with particular emphasis on the benefits derived from binaural implantation and intensive speech therapy work. The research results allowed us to conclude that speech is the preferred way of communication of the examined girl. She achieved very high phonic communication skills, similar to the level of her hearing peers. Gesture and facial communication has an auxiliary function. It is based on natural gestures, although the child has had an episode of learning the basics of sign language. Analysis of the child’s speech development history allows us to notice a strong relationship between the implantation time and the acceleration of the dynamics of his speech development.

    Opis:
    Wstęp W przemyśle rozrywkowym hałas często osiąga wysokie poziomy ciśnienia akustycznego, jednak ryzyko uszkodzenia słuchu w tym sektorze nie zostało jeszcze dokładnie ocenione. Celem pracy była ocena związku między ekspozycją na wysoki poziom dźwięku a czasowym przesunięciem progu słuchu u osób pracujących na stanowisku barmana w lokalach rozrywkowych. Materiał i metody Badaniem objęto 18 barmanów (średni wiek: 25±7 lat) zatrudnionych w klubie muzycznym (N = 8), pubie (N = 5) i dyskotece (N = 5). Poziomy dźwięków oraz charakterystyka częstotliwościowa hałasu były określane za pomocą dozymetrii indywidualnej. Progi słuchu oceniano za pomocą audiometrii tonalnej przeprowadzanej przed rozpoczęciem dnia pracy oraz bezpośrednio (do 15 min) po jego zakończeniu. Badania słuchu przeprowadzono u barmanów w czasie 2 lub 3 sesji badawczych podczas pracy w weekendy. Uzyskano 92 audiogramy przed- i poekspozycyjne. Wyniki Uśrednione równoważne poziomy dźwięku odniesione do 8-godzinnego dnia pracy w ocenianych 3 lokalach muzycznych wynosiły 95 dBA, przekraczając ponad czterokrotnie dopuszczalne prawnie normy. U 77% badanych osób wykazano przynajmniej w 1 sesji pomiarowej czasowe przesunięcia progów słuchu ≥ 10 dB HL dla częstotliwości 4 kHz. Wnioski Osoby pracujące na stanowisku barmana stanowią grupę zawodową o podwyższonym ryzyku utraty słuchu. Niezbędne jest zwiększanie świadomości tego faktu oraz wdrażanie u tych pracowników programów ochrony słuchu, zgodnie z dyrektywą Komisji Europejskiej (EU 2003/10/WE). Med. Pr. 2019;70(1):17–25
    Background Noise in entertainment industry often reaches high sound pressure levels. Nevertheless, the risk of hearing loss in this sector is insufficiently recognized. The aim of this study was the assessment of the relationship between noise exposure and temporary threshold shifts (TTS) for people working as bartenders at a variety of entertainment venues. Material and Methods The study comprised a total of 18 bartenders (mean age was 25±7 years old) employed at a music club (N = 8), pub (N = 5) and discotheque (N = 5). Personal dosimeters were used for determining noise levels and frequency characteristics. Hearing was evaluated by pre- (before work) and post-exposure (up to 15 min after the end of work) pure tone audiometry. Hearing tests were carried out for bartenders during 2 or 3 sessions while working on weekends. Results The mean personal noise exposure level normalized to a nominal 8-hour working day was 95 dBA, above 4 times higher than the accepted legal limit. The TTS values (10 dB HL or more) were significant at 4 kHz for both ears for 77% of bartenders. Conclusions People working as bartenders represent a professional group with an increased risk of hearing loss. Raising awareness of this fact and implementing hearing protection programs in this group of workers is urgently needed, in line with the European Commission Directive (EU Directive 2003/10/EC).

    Opis:
    The trend of inclusive education in Belarus inspired a series of studies on the possibilities of social integration of pupils with special educational needs. The purpose of the following article is to describe the activities implementing humanistic holistic approach, which aims at social activation of pupils with hearing loss. The participants of the project were pupils from Special School with Hard of Hearing Student's Dormitory No 13 in Minsk. The undertaken actions were aimed at changing the attitudes of passive consumers, socially immature, apathetic, with no initiative men into active participants in the social life. For this reason, it was essential to develop in a young person's personality characteristics such as: inner freedom and independence, self-discipline, self-control, self-management, and the ability of self-reflection. The project was designed to achieve these goals through a specially planned series of cultural and entertainment events participated in by the deaf, their hearing friends, parents, teachers, and representatives of the state and non-governmental organizations. This active model of education consisted of five, associated with each other, phases: diagnostic, implementing special cultural and sport actions, and finally those evaluating and modifying ones. The model assumed 2 basic directions of pupils' development: education in communication and action, as well as cooperation between hearing impaired students with hearing children and adults. Some competitions, festivals, meetings, intellectual games were organized using different technologies and interactive methods, e.g.: volunteering. Analysis of the above-mentioned actions shows that preparing pupils with hearing loss to social integration is a process requiring proper emotional contact and effective communication. Only then do different actions help not only to overcome passivity, lack of self-confidence, but also to arouse interests and develop creativity. Positive effects of the implemented project can be seen, since the graduates of this experimental school went on to study at numerous Belarusian universities.
    Nurt edukacji włączającej na Białorusi zainspirował serię badań nad możliwościami integracji społecznej uczniów ze specjalnymi potrzebami edukacyjnymi. Celem artykułu jest opis działań wdrażających humanistyczną koncepcję holistyczną, mającą na celu zaktywizowanie społeczne uczniów z uszkodzeniami słuchu. W projekcie wzięli udział uczniowie Szkoły Specjalnej z internatem dla Dzieci Niedosłyszących nr 13 w Mińsku. Podjęte działania miały przekształcać postawy biernych konsumentów, niedojrzałych społecznie, apatycznych, bez inicjatywy – w twórczych, aktywnych uczestników życia społecznego. W tym celu należało wykształcić w młodym człowieku takie cechy osobowości, jak: wewnętrzna wolność i niezależność, samodyscyplina, samokontrola, samorządność, zdolność do refleksji. W projekcie zaplanowano osiągnięcie owych celów poprzez odpowiednio zaplanowany szereg imprez kulturalno-rozrywkowych, w których uczestniczyli niesłyszący, ich słyszący koledzy, rodzice, nauczyciele oraz przedstawiciele organizacji państwowych i pozarządowych. Ten aktywny model edukacji składał się z pięciu powiązanych ze sobą etapów: diagnostycznych, wdrażających konkretne działania kulturalne i sportowe oraz ewaluacyjnych i modyfikujących. Model zakładał dwa podstawowe kierunki rozwoju uczniów: kształcenie w komunikacji i w działaniu oraz współpraca uczniów z uszkodzeniami słuchu ze słyszącymi dziećmi i dorosłymi. Organizowano konkursy, festiwale, wystawy, spotkania, gry i zabawy intelektualne, wykorzystując różne technologie informatyczne oraz metody interaktywne, np. wolontariat. Analiza powyższych działań pokazuje, że przygotowanie uczniów z uszkodzeniami słuchu do integracji społecznej to proces, którego podstawą jest dobry kontakt emocjonalny i skuteczna komunikacja. Dopiero wtedy różne działania pomagają przezwyciężyć bierność, brak wiary we własne siły, rozbudzić zainteresowania, rozwijać kreatywność. Pozytywne efekty wdrożonego projektu są widoczne, gdyż absolwenci tej eksperymentalnej szkoły podjęli studia na wielu białoruskich uczelniach wyższych.

    Opis:
    The article discusses an important social aspect concerning speech disorders, also in people with disabilities, and the methods of their presentation in the film space. The main aim of the article is the way of presenting dysfunctions in the field of communication in a cinematic work. Other tasks of the article include attempts to answer the following questions: “does the environment influence the development of communication skills of people with disabilities?”, “how does the film show the relationships of people with speech disorders and disabilities in contacts with loved ones?”, and to “what extent is the film image consistent with the scientific description of a given disorder?”. The analytical chapters in the article are devoted to three disorders and selected feature films in which the actors present the language and communication skills of film characters struggling with speech disfluency, hearing dysfunction and cerebral palsy.
    W artykule poruszono ważny społecznie temat dotyczący zaburzeń mowy, także u osób z niepełnosprawnością, oraz metod ich prezentacji w przestrzeni filmowej. Podstawowym celem artykułu jest sposób przedstawienia dysfunkcji w zakresie komunikacji w dziele filmowym. Artykuł próbuje odpowiedzieć na pytania: „czy otoczenie wpływa na rozwój umiejętności komunikacyjnych osób z dysfunkcjami?”, „w jaki sposób dzieło filmowe pokazuje relacje osób z zaburzeniami mowy oraz z niepełnosprawnością w kontaktach z najbliższymi?” oraz „na ile obraz filmowy jest zgodny z opisem naukowym danego zaburzenia?”. Zawarte w artykule rozdziały analityczne poświęcone zostały trzem zaburzeniom oraz wybranym filmom fabularnym, w których aktorzy prezentują umiejętności językowe i komunikacyjne postaci filmowych zmagających się z niepłynnością mówienia, dysfunkcją słuchu oraz mózgowym porażeniem dziecięcym.

    Opis:
    The aim of following article is to describe a glottodidactic experiment investigating whether persons with hearing loss and sever speech impairments are able to create lexical- grammatical generalizations of concepts in English. The opening thesis statement indicates that there are three types of verbal generalizations: lexical, grammatical, and lexical-grammatical, as well as the fact that in ontogenesis each type of generalization is acquired in stages (4 stages). A little child, in order to build the system of lexical and grammatical generalizations needs to perform a great analytical work. In the experiment three groups participated: a group consisting of subjects with hearing loss (15 people), with severe speech disorders (16 people) and the control group of hearing, healthy people (15 people). The findings from the research showed that those tested who were from the main groups achieved slightly lower results than the subjects from the control group in the process of semantization and modeling expressions in English. Persons with hearing loss performed this task better than subjects with speech impairments. Achieving such high results by the tested groups was possible mainly thanks to the directed, controlled, and arduous work, as well as the additional working time. This may be daunting, however, the experiment proves that obtaining high results in this area is possible, even despite the perception and expression limitations.
    Celem artykułu jest opis eksperymentu glottodydaktycznego, w którym chciano sprawdzić, czy osoby z uszkodzeniami słuchu i poważnymi zaburzeniami mowy są w stanie tworzyć uogólnienia leksykalno-gramatyczne pojęć w języku angielskim. Postawiono tezę wyjściową, że istnieją trzy rodzaje uogólnień słownych: leksykalne, gramatyczne i leksykalno-gramatyczne oraz że w ontogenezie każdy typ uogólnień przyswajany jest etapowo (4 etapy). Małe dziecko, aby zbudować system uogólnień leksykalnych i gramatycznych, musi wykonać ogromną pracę analityczną. Przeprowadzony eksperyment, w którym uczestniczyły trzy grupy badane: grupa osób z uszkodzeniami słuchu (15 osób), grupa osób z poważnymi zaburzeniami mowy (16 osób) oraz grupa kontrolna osób słyszących, zdrowych (15 osób), wykazał, że badani z grup głównych osiągnęli niewiele niższe wyniki od grupy kontrolnej w procesie semantyzacji i modelowania wyrażeń w języku angielskim, w tym osoby z uszkodzeniami słuchu poradziły sobie z tym zadaniem lepiej niż badani z zaburzeniami mowy. Osiągnięcie tak wysokich wyników przez badane grupy główne było możliwe dzięki kierowanej, kontrolowanej, wytężonej pracy i dodatkowemu nakładowi czasu, co może być zniechęcające, ale eksperyment udowadnia, że osiąganie wysokich wyników w tym zakresie jest możliwe, pomimo ograniczeń percepcyjnych i ekspresyjnych.

    Opis:
    Hearing is one of the most important human senses closely associated with the organ of hearing and balance. Patients with sudden hearing loss sometimes report ear fullness, tinnitus or vertigo. Hearing disturbances is a very unpleasant sensation lowering the quality of life. Sudden hearing loss is mostly caused by otologic diseases but also disturbances of brain circulation, brain injury, viral (mumps, rubella, herpes zoster) and bacterial infections, bone diseases, bone tumours, 8th nerve tumours, genetic disorders, autoimmune diseases (e.g. multiple sclerosis), ototoxic medications and many others. Hearing disorders are generally divided into central and peripheral, the latter divided into conductive and perceptive. Deafness is a worrying symptom not only for the patient but also for a clinical neurologist. Diagnosis is based on the past history, physical examination, both otolaryngological and neurological, diagnostic investigations, audiological investigation, atrial excitability testing (caloric tests, electronystagmography) depending on clinical indications, neuroradiological investigations, brainstem auditory evoked potentials, blood tests and others, which enables instituting a proper treatment.
    Słuch to jeden z najważniejszych zmysłów człowieka, ściśle związany z narządem słuchu i równowagi. Nagłe lub szybko postępujące upośledzenie słuchu, któremu mogą towarzyszyć szumy uszne, uczucie zatkania ucha czy zawroty głowy, jest dla pacjenta nieprzyjemne i w dużym stopniu obniża jakość jego życia. Wśród przyczyn nagłych zaburzeń słuchu wymienia się przede wszystkim choroby laryngologiczne, ale też zaburzenia krążenia mózgowego, urazy czaszkowo-mózgowe, infekcje wirusowe (wirusy świnki, różyczki, półpaśca) i bakteryjne, choroby kości, guzy nerwu VIII, choroby genetyczne, schorzenia o podłożu autoimmunologicznym (np. stwardnienie rozsiane), leki ototoksyczne i wiele innych. Zaburzenia słuchu dzielimy na ośrodkowe i obwodowe, te drugie natomiast – na przewodzeniowe i odbiorcze. Głuchota jest objawem bardzo niepokojącym nie tylko dla pacjenta, lecz także dla neurologa. W jej przypadku kluczową rolę odgrywają: wywiad, badanie przedmiotowe, w tym badanie otolaryngologiczne, neurologiczne i audiologiczne, badanie pobudliwości przedsionków (próby kaloryczne, elektronystagmografia) oraz – w zależności od wskazań klinicznych – badania neuroobrazowe, badanie słuchowych potencjałów wywołanych z pnia mózgu, badania laboratoryjne krwi i inne, a następnie podjęcie właściwego leczenia.

    Opis:
    Oznaczono aktywność wybranych enzymów antyoksydacyjnych: dysmutazy ponadtlenkowej (SOD), katalazy (CAT) i peroksydazy glutationowej (GPx) w erytrocytach oraz stężenie substancji reagujacych z kwasem tiobarbiturowym (TBARS) w osoczu i w erytrocytach osób poddanych działaniu hiperbarii tlenowej (HBO) z powodu wystąpienia nagłego niedosłuchu nerwowo-czuciowego (SSNHL). Krew żylną do badań pobrano bezpośrednio przez zabiegiem HBO oraz ok. 5 min po wyjściu z komory hiperbarycznej. W grupie badanej wyodrębniono 2 podgrupy różniące się wiekiem: grupę I stanowiły osoby poniżej 35 roku życia, grupę II powyżej 50 lat. Uzyskane wyniki poddano analizie statystycznej z wykorzystaniem testu T-Studenta. Za istotne statystycznie uznano różnice przy poziomie istotności p<0,05. Wykazano 5 min po wyjściu z komory hiperbarycznej istotne statystycznie obniżenie się aktywności CAT u wszystkich osób analizowanych łącznie (p<0,01) oraz w I grupie (p<0,05). Zaobserwowano ponadto znamienne statystycznie zmniejszenie się stężenia TBARS w erytrocytach w II grupie chorych (p<0,05). Wykazano, że jednorazowa ekspozycja hiperbaryczna wpływa na równowagę oksydacyjno-antyoksydacyjną o czym świadczy m.in. istotne statystycznie obniżenie się aktywności katalazy w erytrocytach. Możliwe, że odpowiedź antyoksydacyjna na działanie HBO zależy do wieku osób badanych.
    The activity of selected antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) in erythrocytes, and the concentration of thiobarbituric acid reactive substances (TBARS) in blood plasma and erythrocytes, were determined in people subjected to hyperbaric oxygen (HBO) therapy due to sudden sensorineural hearing loss (SSNHL). Venous blood samples were taken immediately before entering the hyperbaric chamber and 5 min after leaving it. In the study group, two age subgroups were distinguished: group I consisting of subjects under 35 and group II consisting of subjects over 50. The obtained values were analysed statistically using Student’s t-test. Differences were considered as statistically significant at p < 0.05. A statistically significant decrease in the CAT activity was shown 5 min after leaving the hyperbaric chamber in pooled subjects (p < 0.01) and group I (p < 0.05). Furthermore, a statistically significant decrease in the erythrocyte TBARS concentration was observed in group II (p < 0.05). It was demonstrated that a single exposure to hyperbaric oxygen affects the oxidant–antioxidant equilibrium as evidenced by, e.g., a statistically significant decrease in the activity of catalase in erythrocytes. It is possible that the antioxidant response to HBO depends on the age of subjects.

The military impulse noise environment is described, as are the different types of passive and active hearing protectors and the measurement procedures. The different mechanisms that may alter the effectiveness of the hearing protectors as well as their global efficiency when submitted to high-level impulse noise are presented. The paper also discusses how the performance values accessible to the user may be used in different damage risk criteria for continuous and impulse noise.

    Opis:
    Celem artykułu jest zaprezentowanie rezultatów badań własnych dotyczących problematyki jakości życia osób starszych po 60. roku życia oraz poziomu akceptacji utraty sprawności w słyszeniu przez seniorów. Badania miały na celu zidentyfikowanie i określenie zależności między akceptacją utraty prawidłowego słyszenia a jakością życia seniorów z trudnościami w słyszeniu. Przedmiotem badań była jakość życia oraz związek jakości życia z poczuciem akceptacji utraty sprawności w słyszeniu u osób po 60. roku życia. W badaniach zastosowano metodę sondażu diagnostycznego, technikę ankiety (WHOQOL-BREF – Skrócona Wersja Ankiety Oceniającej Jakość Życia; Wielowymiarowa Skala Akceptacji Trudności w Słyszeniu; Test przesiewowy z baterii TSOS). W artykule można się zapoznać z zagadnieniami teoretycznymi dotyczącymi jakości życia osób starszych z trudnościami w słyszeniu. Przedstawiono podstawy metodologicznych badań własnych i zaprezentowano wyniki przeprowadzonych badań oraz wnioski do wykorzystania w późniejszych działaniach na gruncie pedagogiki. Stwierdzono, że im wyższy poziom akceptacji utraty prawidłowego słyszenia, tym wyższa jakość życia badanych seniorów. Z badań wynika konieczność prowadzenia różnorakich działań mających na celu wspieranie seniorów z trudnościami w słyszeniu w ich psychospołecznym funkcjonowaniu. Niezbędne jest podnoszenie świadomości społecznej w obszarze jakości życia starszych osób z trudnościami w słyszeniu.
    The article presents the results of research concerning the quality of life of older people over 60 and the level of acceptance of the loss of hearing performance by seniors. The research was aimed at identifying and determining the relationship between the acceptance of the loss of proper hearing and the quality of life of seniors with difficulties in hearing. The subject of the research was the quality of life and the relationship between the quality of life and the sense of acceptance of the loss of hearing performance in people over 60 years of age. The research took the form of a diagnostic survey using the questionnaire technique (WHOQOL-BREF – Short Version of the Quality-of-Life Survey; Multidimensional Acceptance Scale of Hearing Difficulties; Screening Test with TSOS battery). The article presents theoretical issues related to the quality of life of older people with hearing difficulties, with the methodological basis of this research being presented. The results from the conducted research are presented at the end of the article and a number of conclusions for subsequent activities in the field of pedagogy are drawn. It was found that the higher the acceptance level of the loss of correct hearing, the higher the quality of life of the surveyed seniors. The research shows the need to conduct various activities aimed at supporting seniors with hearing difficulties in their psychosocial functioning. It is necessary to raise social awareness in areas connected with the quality of life of older people with hearing difficulties.
