This report is the first of two detailing a longitudinal follow-up of hearing aid users. Sixty-five subjects were followed for 12 months post-hearing aid fitting. Objective tests included insertion gain, the Speech Perception in Noise (SPIN) test (Kalikow, Stevens & Elliott, 1977; Bilger, Neutzel, Rabinowitz, & Rzeczkowski, 1984) and the Nonsense Syllable Test (NST) (Levitt & Resnick, 1978) presented in quiet and noise backgrounds. Initially each subject’s hearing aid was fit to the revised National Acoustic Laboratories prescriptive formula (NAL-R) (Byrne & Dillon, 1986) using insertion gain measures. Use gain, measured at 6 and 12 months post-fitting, indicated that subjects generally used those prescribed values, except for subjects in the steeply sloping configuration subgroup. The NST and SPIN tests were administered at the fitting and at 1, 3, 6, and 12 months post-fitting. No change in performance, or training effect, was found for the group or for factors of experience, degree of hearing loss, configuration of hearing loss, use time, or circuit type. Failure to demonstrate a training effect may be attributed, in part, to the fact that initial speech recognition testing was done with the hearing aid volume set at the prescribed values. None of the circuits used showed performance superiority, except when comparing scores for the NST obtained in a quiet background to those obtained in a background of speech-weighted noise. In that comparison, the users of adaptive filter circuits exhibited less deterioration of performance in a noise background.

Molecular Aspects

Congenital hypothyroidism (CH) is an endocrine disease commonly found in newborns and is related to the absence or reduction of thyroid hormones (THs), which are essential for development since intrauterine life. Children with CH can develop hearing problems as THs are crucial for the auditory pathway’s development and maturation. Sensory deprivations, especially in hearing disorders at early ages of development, can impair language skills, literacy, and behavioral, cognitive, social, and psychosocial development. In this review we describe clinical and molecular aspects linking CH and 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.

Mobile phone is one of the developing communication tools today. The global debate and controversy regarding the health effects of cell phones continues. There are concerns that radio frequency energy (radio waves) emitted can cause health problems, especially to hearing function. The aim of the study was to find out how "the description of hearing loss with the use of mobile phones in Pekanbaru 12 SMA. The type of research used is descriptive with probality sampling sampling technique where the sample in this study is to take respondents based on random or coincidental in SMA Negeri 12 Pekanbaru which amounted to 249 respondents. Data collection tools using questionnaires as well as examination of auditory function by means of the rinne test used is univariate. The results of the research which was conducted on 23 July - 28 July 2018 showed that of 249 respondents (100%) were all mobile users and from the results of rinne test, 66 respondents (26.5%) had positive hearing loss and 183 respondents (73 , 5%) negative did not experience hearing loss.

Numerous international studies have demonstrated a relationship between HIV/AIDS and auditory function. The aim of this study was to explore this relationship in a group of adults infected with HIV/AIDS attending an outpatient clinic in a hospital located in Gauteng, South Africa. The prevalence of hearing loss; the type, degree and configuration of the hearing loss; the relationship between the hearing symptoms and the progressive stages of the disease, and the type of onset of hearing problems were examined. The results of the study indicated a prevalence rate of hearing loss which was as high as 23% in the sample surveyed. The types of hearing loss included conductive and sensorineural, while the degree of severity ranged from slight to profound in nature. The configuration of the hearing loss was not frequency-range-specific, and the degree of severity did not seem to worsen with the progression of the HIV/AIDS disease. However, there did seem to be an increase in the occurrence of sensorineural hearing loss with the deterioration of patients' immunological status. Analysis of patients' audiological results along with their case history data suggested that their hearing loss may have been caused by opportunistic infections and/or their treatments. These results are discussed in terms of their implications for the clinical management of patients with HIV/AIDS; education of team members; and policy formulation.

Noise induces oxidative stress in the cochlea followed by sensory cell death and hearing loss. The proof of principle that injections of antioxidant vitamins and Mg2+ prevent noise-induced hearing loss (NIHL) has been established. However, effectiveness of oral administration remains controversial and otoprotection mechanisms are unclear. Using auditory evoked potentials, quantitative PCR, and immunocytochemistry, we explored effects of oral administration of vitamins A, C, E, and Mg2+ (ACEMg) on auditory function and sensory cell survival following NIHL in rats. Oral ACEMg reduced auditory thresholds shifts after NIHL. Improved auditory function correlated with increased survival of sensory outer hair cells. In parallel, oral ACEMg modulated the expression timeline of antioxidant enzymes in the cochlea after NIHL. There was increased expression of glutathione peroxidase-1 and catalase at 1 and 10 days, respectively. Also, pro-apoptotic caspase-3 and Bax levels were diminished in ACEMg-treated rats, at 10 and 30 days, respectively, following noise overstimulation, whereas, at day 10 after noise exposure, the levels of anti-apoptotic Bcl-2, were significantly increased. Therefore, oral ACEMg improves auditory function by limiting sensory hair cell death in the auditory receptor following NIHL. Regulation of the expression of antioxidant enzymes and apoptosis-related proteins in cochlear structures is involved in such an otoprotective mechanism.

Simple Snoring

Introduction Obstructive Sleep Apnea Syndrome (OSAS) is characterized by recurrent episodes of prolonged partial or complete obstruction of the upper airways. Several study groups studied the effect of snoring and OSAS on auditory function, showing an increase in the incidence of hearing loss in apneic patients, an earlier onset and/or a degree of hearing loss deeper than in peers. The aim of our study is to evaluate the audiological performance of a population of simple-snoring patients and patients suffering from mild OSAS, and the impact that such pathological condition can have on the auditory function, considering the significant levels of chronic noise. Materials and Methods Data was collected by analyzing audiometric exams on snoring patients and a control group of non-snoring patients. Our study included simple snoring patients without OSAS (AHI < 5) or with low level of OSAS (5< AHI < 15). Possible hearing loss was classified in a crescent scale (A-B-C-D-E), from greater to minor auditory performance, according to the indications of the national protocol of occupational medicine for evaluation of hearing loss in patients exposed to chronic noise. Results We have found independence between simple snorers, mild-OSAS snorers and non-snoring patients compared to the scale of hearing performance classification. Conclusions Our results show a distribution of hearing loss in the different groups that appear independent of the presence or absence of snoring, complicated or uncomplicated by mild OSAS.
