Active clinical trials for "Hearing Loss"

The purpose of this study is to evaluate the long-term safety and efficacy of the Esteem® Hearing Implant in subjects suffering from moderate to severe hearing loss.

Our main objective is to study how the extent of reorganization of the central auditory system is related to the binaural integration in cochlear implanted subjects with asymmetric hearing loss. Subjects with asymmetric hearing loss treated with a cochlear implant and a control group of normal hearing subjects will perform two tests for binaural integration (speech recognition in noise and spatial localization) and two tasks of non-linguistic sounds perception.

Communication on telephone is challenging for people with hearing loss. For hearing aid users, for instance, the inventions for improving speech intelligibility on the phone range from an integrated tele coil and individual hearing programs to specially designed phone devices. No formal studies involving these devices have been carried out with CI users. Thus, this comparative study includes hearing aid as well as CI and bimodal users to evaluate different hearing solutions for communication on telephone in terms of intelligibility and ease of use.

The primary purpose of the research is to study how individuals who wear cochlear implants process sounds in noisy environments and also whether newly designed programs can help improve the communicative ability of cochlear implant patients in noisy situations.

The reason for this study is to evaluate a new hearing aid product generation replacing the one on the market. The goal is to evaluate the audiological performance, usability as well as features and functions.

The trial is in three stages and will translate and validate screening and assessment instruments for use with deaf children. The first stage is modifying the screening and assessment instruments (ADI-R and ADOS-2) for use with deaf children. This will involve choosing the most promising screening instrument (SRS-2) based on the systematic review and the expertise of a review panel, which contains experts and public and patient involvement (PPI). This phase of the study seeks a wide range of user (parents/ carers and young people) views and experiences about the symptomatology and presentation of deaf children with autism, comparing this to hearing children with autism, and deaf children without autism. The second stage is to ensure that the newly modified instruments are accessible to deaf children and deaf parents by making any necessary translations from English into British Sign Language. This involves a strict translation and back translation methodology with reiterations until successful translation is achieved. For stage three in order to ensure that the new questionnaires are successfully identifying children and young people with Autism Spectrum Disorder, the modified instrument will be validated using a 'gold standard'. The current 'gold standard' for the mental health screening of Deaf children is a clinical interview administered by experienced senior multidisciplinary deaf child mental health clinicians.

Purpose: to investigate the relationship between time for treatment seeking and audiometric data and self-assessment of handicap for patients in a public hearing healthcare service. Methods: Retrospective study. Records of 152 elderly and 48 adults with hearing impairment were analyzed. The ISO audiometric thresholds average (500 to 4000Hz) and high frequencies average (2000 to 6000Hz), the speech recognition thresholds and the total, social and emotional scores from the Hearing Handicap Inventory for the Adults (HHIA) and Elderly (HHIE) were compared with the time between the onset of hearing complaints and the first treatment seeking. Results: The average time for treatment seeking was 7,6 years. No statistical difference was found between ISO and high frequency audiometric average, HHIA/E scores and time for treatment seeking between adults and the elderly. Weak but significant negative correlations were observed between the audiometric data and time for treatment seeking. There was no relationship between the time for treatment seeking and educational, socioeconomic levels and perception of handicap. Conclusions: The search for treatment seems to be multifactorial. Despite technological advances and changes in access to information and treatment time for treatment seeking was similar to that reported 30 years ago.

Cisplatin and carboplatin induce ototoxicity manifested as sensorineural hearing loss, tinnitus, and/or vestibular disturbances. Ototoxicity is induced via damage to inner ear structures by reactive oxygen species. Previous animal studies demonstrated that transtympanic injection of Ringer's Lactate (RL) provided near complete otoprotective effect against cisplatin. The purpose of this study is to determine if transtympanic administration of Ringer's Lactate via a pressure equalising (PE) tube in patients undergoing platinum based chemotherapy treatment will prevent tinnitus, vestibular dysfunction and hearing loss especially at high frequencies. Pre- and post- chemotherapy treatment audiometry will be measured and statistically analysed for significance.

Objective: To evaluate the correlation between audiometric thresholds, pitch matching (PM), minimum masking level (MML), Tinnitus Handicap Inventory (THI) and the Beck Depression Inventory (BDI) in tinnitus patients. Subjects: 48 patients with tinnitus as the main complaint from OTOSUL, Otorrinolaringologia Sul-Fluminense, Volta Redonda, RJ, Brasil and Centro de Tratamento e Pesquisa em Zumbido, Belo Horizonte, MG, Brasil. Method: Subjects performed tonal audiometry, Pitch Matching (PM) and Minimum Masking Level (MML) for tinnitus. They also fulfilled the Tinnitus Handicap Inventory (THI) and Beck Depression Inventory (BDI). Data was statistically compared for correlation between audiometric thresholds, psycho-acoustic measures and questionnaires.

Disequilibrium between acid and base in the inner ear was suggested to be an important factor leading to hearing impairment associated with SLC26A4 mutations. For acid-base homeostasis in the inner ear, gastric-type proton pumps might demonstrate antagonistic effects to pendrin, the protein encoded by SLC26A4. To investigate whether proton pump inhibitors might prevent or treat acute fluctuating hearing loss related to SLC26A4 mutations, we launch the current double-blind randomized clinical trial.
