Active clinical trials for "Hearing Loss"

The purpose of study is to determine the diagnostic value of Hearing test program on smart phone for detected patients who has hearing loss.

Hearing impairment is the most frequent sensory deficit in humans and affects one newborn out of 500. The prevalence rises to 3,5/1000 in teenagers due to retarded forms. Most of hearing impairments (about two thirds) have a genetic origin, with recessive, dominant or X-linked mode of inheritance. Some rare forms can be linked to mitochondrial DNA. Molecular diagnosis (i.e. defining the molecular basis of the disease, genes and precise DNA variants) is essential for the follow-up of patients and families. The project intends to perform exome sequencing on 30 samples of families presenting with hearing impairment. Families have been included based on the genetic origin of the hearing impairment (familial cases) and the exclusion of the involvement of 74 known deafness genes. Exome sequencing (sequencing of the coding regions of all known genes, about 22,000) in these cases may underly new gene/disease relationships.

The purpose of this study is to measure the size of the round window niche and its relation to the mastoid segment of the facial nerve and the mastoid cortex, using high resolution computerized tomography of the temporal bone, in order to assess preoperatively what is the extent of obstruction of the round window membrane and whether there is a surgical possibility of round window approach in the insertion of electrode array into the cochlea

The present cross-sectional study aims to examine the cognitive capabilities of older adults, aged 50 to 89, with normal hearing or age-related hearing loss by means of the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing impaired individuals (RBANS-H). Secondly, the correlations between cognition on the one hand and hearing and speech reception capabilities on the other hand are investigated. For this purpose, twenty participants are included in the age categories 50 to 59, 60 to 69, 70 to 79 and 80 to 89, bringing the total number to 80. Three questionnaires are administered to the participants: the Health Utilities Index-2/3 (HUI 2/3), Dizziness Handicap Inventory (DHI) and a general questionnaire on education and profession, medical history, hearing aid use and tinnitus. Also an audiological examination is performed, including pure tone audiometry, speech in quiet and speech in noise audiometry. Finally, cognition is assessed using the RBANS-H.
