Opis:
Niniejszy artykuł jest studium przypadku pięcioletniej dziewczynki zarażonej wirusem cytomegalii, z prelingwalnym, odbiorczym uszkodzeniem słuchu głębokiego stopnia, bilateralnie implantowanej. Celem artykułu jest opis badań dotychczasowego rozwoju oraz aktualnych umiejętności komunikacyjnych dziecka w kontekście wczesnej diagnozy, wczesnej obuusznej implantacji oraz systematycznej terapii logopedycznej badanego dziecka. 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:
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:
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

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.

The aim of the study was to compare the extended high-frequency (EHF) hearing thresholds (10–16 kHz) in tinnitus and non-tinnitus ears, in a group of 98 patients with unilateral tinnitus and normal hearing at standard audiometric frequencies, in a 0.125–8 kHz range. 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.

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.

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:
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.

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.

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:
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

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.

Opis:
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.
