AbstractCongenital sensorineural hearing loss (SNHL) affects thousands of infants each year and results in significant delays in speech and language development. Previous studies have shown that early exposure to a simple augmented acoustic environment (AAE) can limit the effects of progressive SNHL on hearing sensitivity. However, SNHL is also accompanied by “hidden hearing loss” that is not assessed on standard audiological exams, such as reduced temporal processing acuity. To assess whether sound therapy may improve these hidden deficits, a mouse model of congenital SNHL was exposed to simple or temporally complex AAE. Peripheral function and sound sensitivity in auditory midbrain neurons improved following exposure to both types of AAE. However, only exposure to a novel, temporally complex AAE significantly improved a measure of temporal processing acuity, neural gap-in-noise detection in the auditory midbrain. These experiments suggest that targeted sound therapy may improve hearing outcomes for children suffering from congenital SNHL.

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.

Extended Frequency

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.

Hearing Function

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.
