This study was undertaken to quantify hearing thresholds in a large sample of percussionists and to evaluate factors that might increase or decrease a percussionist's risk for music-induced hearing loss. Audiometric and musical history data were collected from 315 percussionists attending the Percussive Arts Society International Convention in Louisville, Kentucky, in November 2004. Hearing thresholds for percussionists were compared to an age- and gender-matched, otologically normal reference population. Results indicate that hearing thresholds of percussionists are significantly worse than those of their age- and gender-matched peers, although differences appear to be small. Hearing was worse in the left ear of percussionists. The prevalence of hearing loss was 39% in percussionists vs. 9% in the reference population. Factors identified as increasing the risk for hearing loss included using amplification systems, playing rock/pop music, having more years of experience, and considering oneself a professional. Increased playing time and playing classical or jazz music were not found to increase a percussionist's risk for hearing loss. Benefits of wearing hearing protection devices (HPDs) were observed only for individuals who used foam earplugs when practicing. It is recommended that percussionists not only use HPDs and decrease practice and performance intensity levels but also participate in annual audiologic evaluations, including otoacoustic emission testing, to prevent music-induced hearing loss.

Objectives - to study hearing thresholds at high frequencies in elderly and senile patients, taking into account the age norm and the presence of comorbid diseases. Material and methods. 111 patients aged from 50 to 97 years (mean age 70.5 ± 2.1) were examined, their age, auditory function, and concomitant diseases were also registered. Results. The measured average auditory thresholds at high frequencies, if compared to the age-related standards for auditory sensitivity, have revealed an underestimated hearing loss in 12.6% of patients. The presence of concomitant diseases has a significant impact on the development of chronic sensorineural hearing loss in each age group. Conclusion. Audiometry in an extended frequency range in elderly patients with concurrent diseases can improve the hearing examination algorithm.

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.

ObjectivesTo investigate the prevalence of comorbid mental health conditions and physical disabilities in a whole country population of adults aged 25+ with and without reported autism.DesignSecondary analysis of Scotland’s Census, 2011 data. Cross-sectional study.SettingGeneral population.Participants94% of Scotland’s population, including 6649/3 746 584 adults aged 25+ reported to have autism.Main outcome measuresPrevalence of six comorbidities: deafness or partial hearing loss, blindness or partial sight loss, intellectual disabilities, mental health conditions, physical disability and other condition; ORs (95% CI) of autism predicting these comorbidities, adjusted for age and gender; and OR for age and gender in predicting comorbidities within the population with reported autism.ResultsComorbidities were common: deafness/hearing loss—17.5%; blindness/sight loss—12.1%; intellectual disabilities—29.4%; mental health conditions—33.0%; physical disability—30.7%; other condition—34.1%. Autism statistically predicted all of the conditions: OR 3.3 (95% CI 3.1 to 3.6) for deafness or partial hearing loss, OR 8.5 (95% CI 7.9 to 9.2) for blindness or partial sight loss, OR 94.6 (95% CI 89.4 to 100.0) for intellectual disabilities, OR 8.6 (95% CI 8.2 to 9.0) for mental health conditions, OR 6.2 (95% CI 5.8 to 6.6) for physical disability and OR 2.6 (95% CI 2.5 to 2.8) for other condition. Contrary to findings within the general population, female gender predicted all conditions within the population with reported autism, including intellectual disabilities (OR=1.4).ConclusionsClinicians need heightened awareness of comorbidities in adults with autism to improve detection and suitable care, especially given the added complexity of assessment in this population and the fact that hearing and visual impairments may cause additional difficulties with reciprocal communication which are also a feature of autism; hence posing further challenges in assessment.

The Relationship

Background: Globally, under-nutrition and hypertension in children has been associated with the risk of developing cardiovascular disease (CVD) in adulthood. The main objective of this study was to investigate the relationship between under-nutrition and hypertension, furthermore, to determine the risk of developing hypertension due to under-nutrition. Methods: The study comprised of 1701 participants (874 boys and 827 girls) between the ages of 9 and 17 years old. All anthropometric and blood pressure measurements were taken according to standard procedures. Mid-upper arm circumference (MUAC), body mass index (BMI), upper arm fat area (UFA), total upper arm area (TUAA) and upper arm muscle area (UMA) of Ellisras children were compared with the National Health and Nutrition Examination Survey III reference population. The linear regression models were used to determine the relationship between under-nutrition with hypertension for unadjusted and then adjusted for age and gender. The logistic regression model was used to determine the risk of under-nutrition on developing hypertension for unadjusted and adjusted for age and gender. Results: There was a positive significant (p < 0.0001) association between all under-nutrition variables (MUAC, BMI, UFA, TUAA and UMA) and systolic blood pressure (SBP; beta ranges between 0.84 and 2.78), and diastolic blood pressure (DBP; beta ranges between 0.3 and 1.08 before adjusting and after adjusting for age and gender (SBP, beta ranges between 0.59 and 2.00 and DBP (beta ranges between 0.24 and 0.80. Conclusion: The prevalence of under-nutrition was high while the prevalence of hypertension was low in this study. The mean under-nutrition variables (BMI, UFA, UMA and MUAC) of Ellisras children were far lower compared to the NHANES III reference population. Hypertension was significantly associated with under-nutrition in this study.

ABSTRACT Purpose This study aimed to evaluate the effects of complete external ear canal occlusion on hearing thresholds with aging. The goal was to decide which tuning fork is more appropriate to use for the contralateral occlusion test (COT), in individuals of different ages. Methods Forty-two normal hearing subjects between 21 and 67 years were divided into three age groups (20-30 years, 40-50 years, and 60-70 years). Participants underwent sound field audiometry tests with warble tones, with and without ear canal occlusion. Each ear was tested with the standard frequencies (250, 500, 1000, and 2000 Hz). The contralateral ear was suppressed by masking. Results Hearing thresholds showed an increase as the frequency increased from 20.85 dB (250 Hz, 20-30 years group) to 48 dB (2000 Hz, 60-70 years group). The threshold differences between occlusion and no occlusion conditions were statistically significant and increased ranging from 11.1 dB (250 Hz, 20-30 years group) to 32 dB (2000 Hz, 20-30 years group). We found statistically significant differences for the three age groups and for all evaluations except to 500 Hz difference and average difference. The mean hearing loss produced by occlusion at 500 Hz was approximately 19 dB. We found no statistically significant differences between right and left ears and gender for all measurements. Conclusion We conclude that the use of the 512 Hz tuning fork is the most suitable for COT, and its use may allow clinicians to distinguish mild from moderate unilateral conductive hearing loss.

AbstractObjective:To investigate hearing loss in patients with Behçet's disease.Materials and methods:Twenty-four consecutive cases of Behçet's disease and 24 sex- and age-matched controls were included in this study. Pure tone and high frequency audiometric tests were performed and pure tone average hearing thresholds calculated for both groups. Transient evoked otoacoustic emission testing was also performed.Results:Pure tone audiometry showed a sensorineural hearing loss in 15 of the Behçet's disease ears. Hearing thresholds were significantly higher in the study group than in the control group, on both pure tone frequency (except 0.5 kHz) and high frequency audiometry. Significant reductions in transient evoked otoacoustic emission amplitude were found at 1.4 and 2 kHz in the Behçet's disease patients. There were no significant differences in reproducibility, stimulus intensity or stability, comparing the Behçet's disease patients and controls.Conclusion:Significantly lower mid-frequency amplitudes were found in Behçet's patients on transient evoked otoacoustic emission testing.

Background: Auditory development in children with hearing loss, including the perception of prosody, depends on having adequate input from cochlear implants and/or hearing aids. Lack of adequate auditory stimulation can lead to delayed speech and language development. Nevertheless, prosody perception and production in people with hearing loss have received less attention than other aspects of language. The perception of auditory information conveyed through prosody using variations in the pitch, amplitude, and duration of speech is not usually evaluated clinically. Purpose: This study (1) compared prosody perception and production abilities in children with hearing loss and children with normal hearing; and (2) investigated the effect of age, hearing level, and musicality on prosody perception. Research Design: Participants were 16 children with hearing loss and 16 typically developing controls matched for age and gender. Fifteen of the children with hearing loss were tested while using amplification (n = 9 hearing aids, n = 6 cochlear implants). Six receptive subtests of the Profiling Elements of Prosody in Speech-Communication (PEPS-C), the Child Paralanguage subtest of Diagnostic Analysis of Nonverbal Accuracy 2 (DANVA 2), and Contour and Interval subtests of the Montreal Battery of Evaluation of Amusia (MBEA) were used. Audio recordings of the children’s reading samples were rated using a perceptual prosody rating scale by nine experienced listeners who were blinded to the children’s hearing status. Study Sample: Thirty two children, 16 with hearing loss (mean age = 8.71 yr) and 16 age- and gender-matched typically developing children with normal hearing (mean age = 8.87 yr). Data Collection and Analysis: Assessments were completed in one session lasting 1–2 hours in a quiet room. Test items were presented using a laptop computer through loudspeaker at a comfortable listening level. For children with hearing loss using hearing instruments, all tests were completed with hearing devices set at their everyday listening setting. Results: All PEPS-C subtests and total scores were significantly lower for children with hearing loss compared to controls (p < 0.05). The hearing loss group performed more poorly than the control group in recognizing happy, sad, and fearful emotions in the DANVA 2 subtest. Musicality (composite MBEA scores and musical experience) was significantly correlated with prosody perception scores, but this link was not evident in the regression analyses. Regression modeling showed that age and hearing level (better ear pure-tone average) accounted for 55.4% and 56.7% of the variance in PEPS-C and DANVA 2 total scores, respectively. There was greater variability for the ratings of pitch, pitch variation, and overall impression of prosody in the hearing loss group compared to control group. Prosody perception (PEPS-C and DANVA 2 total scores) and ratings of prosody production were not correlated. Conclusions: Children with hearing loss aged 7–12 yr had significant difficulties in understanding different aspects of prosody and were rated as having more atypical prosody overall than controls. These findings suggest that clinical assessment and speech–language therapy services for children with hearing loss should be expanded to target prosodic difficulties. Future studies should investigate whether musical training is beneficial for improving receptive prosody skills.
