Objectives: To identify the etiologies of hearing impairment (HI) in schools for students who are deaf and to use a systematic review to summarize reports on the etiologies and clinical and genetic features of HI in Mali.Methods: We included individuals with HI that started before the age of 15 years old. Patients were carefully evaluated under standard practices, and pure-tone audiometry was performed where possible. We then searched for articles published on HI in the Malian population from the databases' inception to March 30, 2020.Results: A total of 117 individuals from two schools for the deaf were included, and a male predominance (sex ratio 1.3; 65/52) was noted. HI was pre-lingual in 82.2% (n = 117), and the median age at diagnosis was 12 years old. The etiologies were environmental in 59.4% (70/117), with meningitis being the leading cause (40%, 20/70), followed by cases with genetic suspicion (29.3%, 21/117). In 11.3% (8/117) of patients, no etiology was identified. Among cases with genetic suspicion, three were syndromic, including two cases of Waardenburg syndrome, while 15 individuals had non-syndromic HI. An autosomal recessive inheritance pattern was observed in 83.3% of families (15/18), and consanguinity was reported in 55.5% (10/18) of putative genetic cases.Conclusion: This study concludes that environmental factors are the leading causes of HI in Mali. However, genetic causes should be investigated, particularly in the context of a population with a high consanguinity rate.

Abstract Introduction: Navy personnel are exposed to several risk factors that increase hearing thresholds and impair hearing. The aim of the study was to determine the prevalence of hearing impairment among Nigerian Navy personnel. Materials and Method: This was a cross sectional study of Nigerian Navy personnel working in various ships. Structured, self-administered questionnaire was used to obtain information on hearing. All the subjects had ear examination and pure tone audiometry of both ears. Results: The prevalence of hearing impairment was 22(14.7%) in the right and 17(11.3%) in the left ears. The Pure Tone Average for the right and left ear were 19.0±8.6dB and 17.4±6.7dB respectively. There was a statistically significant association between noisy work place and total hearing loss (p<.01), pure tone average in the left ear (p<.05) and frequencies of 3000 Hz (p<.05), 2000 Hz (p<.001) and 1000Hz (p<.05) in the left ear. The association between past history of ear infections and pure tone average in the left ear (p<.05) and the frequency 2000 Hz (p<.005) in the left ear were significant. The length of service years, occupational group, age, sex report of change in hearing, non-use of hearing protection and presence of tinnitus did not show significant association with pure tone averages nor on the frequencies tested. Conclusion: The significant unilateral hearing impairment on the right ear suggests the need for more research on hearing impairment in the Nigerian Navy as well as development of a comprehensive hearing conservation programme.

Background: Tinnitus is a common complaint and often of no clinical significance. There are a number of unresolved issues concerning the etiology, pathogenesis, and natural history of tinnitus. There are a few current population-based estimates of the prevalence of tinnitus done in representative large geographic areas, but there is little data from multi-area, large sample studies of tinnitus in China. Purpose: To investigate the prevalence of tinnitus and related factors in a Chinese population. These data would be used to plan and evaluate health-care services. Research Design: We carried out an epidemiologic study of tinnitus as part of an epidemiologic study of ear and hearing disorders that was undertaken in Jiangsu Province, China. A question about tinnitus history was included in a comprehensive questionnaire about hearing. All participants also had both pure tone audiometry and an otological examination. Study Sample: The sample consisted of 6333 people 10 yr of age or older, selected by the methods of probability proportional to size. Data Collection and Analysis: All participants answered a questionnaire concerning their tinnitus and had pure tone audiometry testing and an ear examination. All data were entered using EPIDATD 3.0 software and analyzed by a chi-squared test and test for trends. Results: The overall prevalence of tinnitus was 14.5%, and the standardized rates were 11.4% in the whole country and 12.4% in Jiangsu province. Its prevalence increased with age. The prevalence of tinnitus was 11.9 and 15.6% in urban and rural residents, respectively There was no significant difference in prevalence between men and women. Hearing impairment, history of middle ear infections, and noise exposure were the main risk factors for tinnitus. Conclusion: Tinnitus is a common problem in the population. With the aging of the population, the prevalence of tinnitus will increase. The prevention of tinnitus should focus on hearing impairment screening, otitis media treatment, and noise exposure reduction. Health services in rural areas should emphasize prevention more.

Background: There are not many population-based epidemiological studies on the association between self-reported hearing problems and measured hearing thresholds in older adults. Previous studies have shown that the relationship between self-reported hearing difficulties and measured hearing thresholds is unclear and, according to our knowledge, there are no previous population-based studies reporting hearing thresholds among subjects with hyperacusis. Purpose: The aim was to investigate the prevalence of self-reported hearing problems, that is, hearing difficulties, difficulties in following a conversation in noise, tinnitus, and hyperacusis, and to compare the results with measured hearing thresholds in older adults. Research Design: Cross-sectional, population-based, and unscreened. Study Sample: Random sample of subjects (n = 850) aged 54-66 yr living in the city of Oulu (Finland) and the surrounding areas. Data Collection and Analysis: Otological examination, pure tone audiometry, questionnaire survey Results: The prevalence of self-reported hearing problems was 37.1% for hearing difficulties, 43.3% for difficulties in following a conversation in noise, 29.2% for tinnitus, and 17.2% for hyperacusis. More than half of the subjects had no hearing impairment, or HI (BEHL[better ear hearing level]0.5–4 kHz < 20 dB HL) even though they reported hearing problems. Subjects with self-reported hearing problems, including tinnitus and hyperacusis, had significantly poorer hearing thresholds than those who did not report hearing problems. Self-reported hearing difficulties predicted hearing impairment in the pure-tone average at 4, 6, and 8 kHz, and at the single frequency of 4 kHz. Conclusions: The results indicate that self-reported hearing difficulties are more frequent than hearing impairment defined by audiometric measurement. Furthermore, self-reported hearing difficulties seem to predict hearing impairment at high frequencies (4–8 kHz) rather than at the frequencies of 0.5–4 kHz, which are commonly used to define the degree of hearing impairment in medical and legal issues.

Although several reports exist concerning the occurrence of hearing loss in patients withdisorders of thyroid function, there are still several unsettled issues, such as theincidence and the severity of hearing impairment, the anatomic site of the auditorypathway involved, and the possible pathogenetic mechanisms. Both congenitalhypothyroidism and environmentally based iodine deficiency are established causes ofhearing loss in humans and rodents. Congenital thyroid deficiency in humans can resultin a profound, hearing deficit, which may be prevented by early hormonal replacementtreatment in infants with hypothyroidism. However, the effect of acute or chronichypothyroidism in adults has not been adequately studied, and most information hasbeen obtained from animal experiments, whereas research in humans has been basicallybased on behavioral audiometry. The use of otoacoustic emissions may provide moreinsight into the hearing function of these patients than pure-tone audiometry, since it isconsidered as a sensitive test of the cochlear status. The aim of this study was toevaluate the hearing in a group of patients with acute hypothyroidism, using bothconventional audiometry and transiently evoked otoacoustic emissions (TEOAEs). Material and methods:A group of 52 patients with thyroid carcinoma who underwent total thyroidectomy wasstudied prospectively, All patients were examined before surgery and 6-8 weekspostoperatively. During this period there was no replacement with levothyroxine and themagnitude of thyroxin depletion was monitored by serum thyroid-stimulating hormone levels. On preoperative encounter with each patient, a detailed questionnaire of historyof hearing loss, tinnitus, vertigo, previous ear infections, noise exposure, medications,and recent upper respiratory tract infection was completed. Patients were excluded ifthey were older than 50 years, in order to avoid the phenomenon of presbycusis, or ifthey had a history of cochleovestibular, vascular or neurologic disease, or any other riskfactor for hearing impairment. Pure-tone audiometry, tympanometry and transientlyevoked otoacoustic emissions were performed. A group of healthy volunteers of similarage and sex were used for comparison.Results:(1) Tympanograms were normal, either on initial testing (75%) or on repeat testing(25%).(2) Audiometry showed elevation of all postoperative hearing thresholds, whereas thethresholds varied significantly across frequency.(3) TEOAE testing showed response signal to noise ratios lower in the postoperativesession (hypothyroid state) than in the preoperative session on all measured frequencies.(4) Emission levels varied significantly across frequency, with maximum responseobserved at 2 kHz.(5) Comparison of significant pure-tone and otoacoustic emission shifts for individualears showed more ears affected in otoacoustic emission testing, indicating subclinicalcochlear involvement.(6) Comparison of hearing thresholds and otoacoustic emission levels between patientsand controls showed significant differences on postoperative testing. Conclusions:Acute hypothyroidism in adults causes elevation of hearing thresholds and reducedotoacoustic emissions. The effect on otoacoustic emissions is greater, indicatingsubclinical damage of the cochlear function.

Objective To investigate the association of midlife hypertension with late-life hearing impairment. Study Design Data from the Atherosclerosis Risk in Communities study, an ongoing prospective longitudinal population-based study (baseline, 1987-1989). Setting Washington County, Maryland, research field site. Subjects and Methods Subjects included 248 community-dwelling men and women aged 67 to 89 years in 2013. Systolic blood pressure (SBP) and diastolic blood pressure were measured at each of 5 study visits from 1987-1989 to 2013. Hypertension was defined by elevated systolic or diastolic blood pressure or antihypertensive medication use. A 4-frequency (0.5-4 kHz) better-hearing ear pure tone average in decibels hearing loss (dB HL) was calculated from pure tone audiometry measured in 2013. A cutoff of 40 dB HL was used to indicate clinically significant moderate to severe hearing impairment. Hearing thresholds at 5 frequencies (0.5-8 kHz) were also considered separately. Results Forty-seven participants (19%) had hypertension at baseline (1987-1989), as opposed to 183 (74%) in 2013. The SBP association with late-life pure tone average differed by the time of measurement, with SBP measured at earlier visits associated with poorer hearing; the difference in pure tone average per 10–mm Hg SBP measured was 1.43 dB HL (95% CI, 0.32-2.53) at baseline versus −0.43 dB HL (95% CI, −1.41 to 0.55) in 2013. Baseline hypertension was associated with higher thresholds (poorer hearing) at 4 frequencies (1, 2, 4, 8 kHz). Conclusion Midlife SBP was associated with poorer hearing measured 25 years later. Further analysis into the longitudinal relationship between hypertension and hearing impairment is warranted.

Abstract Background Gelsolin amyloidosis (AGel amyloidosis) is a hereditary form of systemic amyloidosis featuring ophthalmological, neurological and cutaneous symptoms. Previous studies based mainly on patients’ self-reporting have indicated that hearing impairment might also be related to the disease, considering the progressive cranial neuropathy characteristic for AGel amyloidosis. In order to deepen the knowledge of possible AGel amyloidosis-related hearing problems, a clinical study consisting of the Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire, clinical examination, automated pure-tone audiometry and a speech-in-noise test was designed. Results Of the total 46 patients included in the study, eighteen (39%) had self-reported hearing loss. The mean scores in the SSQ were 8.2, 8.3 and 8.6 for the Speech, Spatial and Qualities subscales, respectively. In audiometry, the mean pure tone average (PTA) was 17.1 (SD 12.2) and 17.1 (SD 12.3) dB HL for the right and left ears, respectively, with no difference to gender- and age-matched, otologically normal reference values. The average speech reception threshold in noise (SRT) was − 8.2 (SD 1.5) and − 8.0 (SD 1.7) dB SNR for the right and left ears, respectively, which did not differ from a control group with a comparable range in PTA thresholds. Conclusion Although a significant proportion of AGel amyloidosis patients experience subjective difficulties in hearing there seems to be no peripheral or central hearing impairment at least in patients up to the age of 60 years.

Abstract Background: Ear infections is the leading cause of hearing impairment among children world-wide and a major public health problem in many indigenous populations. Early onset of hearing impairment compromise communication skills and social and psychological development, and monitoring the prevalence in a population is important to assess the need for interventions both at the school-, societal and clinical settings in a population.Methods: 185 children from 5th to 10th grade from Sisimiut town and the nearby settlements participated in a clinical examination to have ear-examination and pure tone audiometry. Participants filled out a questionnaire at home with their parents before the clinical examination, and hearing impairment was collected as individual self-reports and as audiometric measurements. Ear examinations was assessed by two clinicians and if any discrepancy between self-reports and clinical measures they were re-assessed.Results: A total of 185 children between 9 and 15 years of age (median: 11 years, IQR: 10-13) were included, 60% (n=111) were girls. 247 (70%) of the 355 available otoscopies were clinically assessed as normal. Cohen’s Kappa coefficient was 0.31. Eighteen children (10%) were found to have hearing impairment using a PTA of ≥ 25 dB for either low or high frequencies or both as threshold in one or both ears. 32 children (17%) reported hearing impairment to the extent that they were not able to keep up in school, of which half reported that it had lasted for more than one year. 7 of the 32 children reporting hearing impairment (22%) reported that the extent of their hearing impairment was affecting their classroom experience so they were not able to follow. None of the children had hearing aids. Conclusion: Self-reported and clinically screening for hearing impairment are two different concepts. Even though the two concepts are statistically correlated, the correlation coefficients are low. The contextual processing in which perceived hearing impairment is assessed in a social environment seems to conceptually differ from the measure of hearing by pure tone audiometry. Since both measure hearing impairment, the choice of measure should relate to the purpose and method of the investigation.

The Impact

Purpose We aimed to develop and validate the Musicians' Hearing Handicap Index (MHHI), a new self-evaluation tool for quantifying occupation-related auditory difficulties in music professionals. Although pure-tone audiometry is often considered the “gold standard” and is usually employed as the main instrument for hearing assessment, it cannot fully describe the impact of hearing dysfunction. The MHHI is an attempt to complement the hearing impairment assessment toolbox and is based on a unique approach to quantify the effects of hearing-related symptoms or hearing loss on the performance of musicians and other music industry professionals. Method An initial set of 143 questionnaire items was successively refined through a series of critical appraisals, modifications, and suggestions. This yielded an intermediate questionnaire consisting of 43 items, which was administered to 204 musicians and sound engineers. After exploratory factor analysis, the final form of the MHHI questionnaire was obtained, consisting of 29 items. The questionnaire's test–retest reliability, internal consistency, discriminating power, content validity, criterion validity, and aspects of construct validity and inherent conceptual structure were assessed. Results Exploratory factor analysis revealed a combination of four common factors for the 29 validated questionnaire items. They were named “impact on social and working lives,” “difficulties in performance and sound perception,” “communication difficulties,” and “emotional distress.” The MHHI was shown to be a valid and reliable instrument to assess musicians' and sound engineers' occupational difficulties due to hearing impairment and related symptoms. Conclusion The ability of the MHHI to discriminate between groups of music professionals with different auditory symptoms or pure-tone audiometry thresholds suggests that auditory symptoms might influence a professional's performance to an extent that cannot be assessed by a pure-tone audiogram.
