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.

Opis:
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.

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.

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.

Opis:
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.

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.

Opis:
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.
