Purpose The effects of neurological diseases on the auditory system have been a notable issue for investigators because the auditory pathway is closely associated with neural systems. The purposes of this study are to evaluate the efferent auditory system function and hearing quality in Parkinson's disease (PD) and to compare the findings with age-matched individuals without PD to present a perspective on aging. Method The study included 35 individuals with PD (mean age of 48.50 ± 8.00 years) and 35 normal-hearing peers (mean age of 49 ± 10 years). The following tests were administered for all participants: the first section of the Speech, Spatial and Qualities of Hearing Scale; pure-tone audiometry, speech audiometry, tympanometry, and acoustic reflexes; and distortion product otoacoustic emissions (DPOAEs) and contralateral suppression of DPOAEs. SPSS Version 25 was used for statistical analyses, and values of p < .05 were considered statistically significant. Results There were no statistically significant differences in the pure-tone audiometry thresholds and DPOAE responses between the individuals with PD and their normal-hearing peers ( p = .732). However, statistically significant differences were found between the groups in suppression levels of DPOAEs and hearing quality ( p < .05). In addition, a statistically significant and positive correlation was found between the amount of suppression at some frequencies and the Speech, Spatial and Qualities of Hearing Scale scores. Conclusions This study indicates that medial olivocochlear efferent system function and the hearing quality of individuals with PD were affected adversely due to the results of PD pathophysiology on the hearing system. For optimal intervention and follow-up, tasks related to hearing quality in daily life can also be added to therapies for PD.

Целью исследования был сравнительный анализ жалоб и аудиологических показателей у пациентов сурдологического центра в зависимости от возраста. Представлены результаты обследования 300 первичных пациентов (случайная выборка), обратившихся к сурдологу-оториноларингологу в течение 1 мес. В группу молодых пациентов (19-44 года) вошли 40 человек; в группу среднего возраста (45- 59 лет) - 62 человека; в группу пожилых (60-74 года) - 100 человек; в группу старческого возраста (75-90 лет) - 98 человек. Обследование включало сбор жалоб и анамнеза, ЛОР-осмотр, тональную пороговую аудиометрию, импедансометрию, речевую аудиометрию в наушниках для выявления признаков центральных слуховых расстройств или в свободном звуковом поле для оценки эффективности слухопротезирования. Установлено, что для ранней диагностики тугоухости и профилактики возрастных сенсорнокогнитивных дисфункций целесообразно использовать не только результаты тональной пороговой аудиометрии, но и данные речевой аудиометрии, а также анализ субъективных жалоб. Результаты работы свидетельствуют о необходимости организации скрининга состояния слуха в рамках диспансеризации населения старше 60 лет. The aim of the study was a comparative analysis of complaints and audiological findings in patients of the audiological center depending on their age. The results of the examination of 300 fi rstly consulted patients (random sample) are presented. The group of young patients (19-44 years) included 40 people; middle age (45-59 years) - 62 people; elderly (60-74 years) - 100 people; senile age (75-90 years) - 98 people. The survey included the collection of complaints and anamnesis, ENT checkup, pure tone audiometry, impedancemetry, speech audiometry in headphones to detect the signs of Central Auditory Processing Disorder or in the free sound field to assess the effectiveness of hearing aids. It was found that for early diagnosis of hearing loss and prevention of age-related sensory-cognitive dysfunction, it is advisable to use not only the results of pure tone audiometry, but also the data of speech audiometry, as well as the analysis of subjective complaints. The results of the work indicate the need for hearing screening in the population over 60 years old.

Next phase of experiment TEST is aimed to evaluate microbial viability after a prolonged external exposure on the International space station (ISS). Methanogenic archaea isolated from various habitats have been tested in ground facilities for the ability to survive exposure to such open space factors as UV and vacuum. Methanosarcina mazei S-6T (VKM B-1636T) was found to be the most viable and, therefore, suitable for the experiment. Our investigations showed that the Methanosarcina mazei population maintained viability in the course of 24-month exposure. On this evidence we conclude that genome of this metanogenic archaea possesses mechanisms against the space vacuum, UV and thermal differences that, probably, underlie the ability of the strain to form peculiar cyst-like dormant cells.

ABSTRACT Objective To assess central auditory function in Friedreich's ataxia. Methods A cross-sectional, retrospective study was carried out. Thirty patients underwent the anamnesis, otorhinolaryngology examination, pure tone audiometry, acoustic immittance measures and brainstem auditory evoked potential (BAEP) assessments. Results The observed alterations were: 43.3% in the pure tone audiometry, bilateral in 36.7%; 56.6% in the BAEP test, bilateral in 50%; and 46.6% in the acoustic immittance test. There was a significant difference (p < 0.05) in the comparison between the tests performed. Conclusion In the audiological screening, there was a prevalence of the descending audiometric configuration at the frequency of 4kHz, and absence of the acoustic reflex at the same frequency. In the BAEP test, there was a prevalence of an increase of the latencies in waves I, III and V, and in the intervals of interpeaks I-III, I-V and III-V. In 13.3% of the patients, wave V was absent, and all waves were absent in 3.3% of patients.

AbstractObjectivesSodium bromate is a strong oxidant, and bromate intoxication can cause irreversible severe-to-profound sensorineural hearing loss. This paper reports the first case in the English literature of bromate-induced hearing loss with hearing recovery measured by formal audiological assessment.Case reportA 72-year-old woman was admitted to hospital with complaints of profound hearing loss, nausea, diarrhoea and anuria after bromate ingestion in a suicide attempt. On admission, pure tone audiometry and auditory brainstem responses showed profound bilateral deafness. Under the diagnosis of bromate-induced acute renal failure and sensorineural hearing loss, continuous haemodiafiltration was performed. When dialysis was discontinued, pure tone audiometry and auditory brainstem responses showed partial threshold recovery from profound deafness.ConclusionSevere-to-profound sensorineural hearing loss is a common symptom of bromate intoxication. Bromate-induced hearing loss may be partially treated, and early application of continuous haemodiafiltration might be useful as a treatment for this intractable condition.

AbstractObjectiveTo evaluate the therapeutic effect that the titanium partial ossicular reconstruction prosthesis and autologous ossicles have on hearing loss after reconstruction of a damaged ossicular chain.MethodsForty-two medical records of treatments carried out from 2013 to 2015 for ossicular chain damage with facial nerve paralysis due to temporal bone fractures were reviewed. The study assessed: causes of damage, pre-operative pure tone audiometry findings, types of intra-operative ossicular chain damage, intra-operative ossicular chain repair methods (titanium partial ossicular reconstruction prosthesis or autologous ossicles) and post-operative pure tone audiometry results.ResultsThe titanium partial ossicular reconstruction prosthesis was used in 26 cases; the average air–bone gap was 32.3 ± 5.3 dB pre-operatively and 12.8 ± 5.3 dB post-operatively. Autologous ossicles were used in 16 cases; the average air–bone gap was 33.4 ± 4.5 dB pre-operatively and 17.8 ± 7.8 dB post-operatively.ConclusionOssicular chain reconstruction is an effective way of improving hearing in patients with ossicular chain damage. The results suggest that repair with either the titanium partial ossicular reconstruction prosthesis or autologous ossicles can improve hearing following ossicular chain injury with facial nerve paralysis caused by a temporal bone fracture.
