Active clinical trials for "Hearing Loss"

The score on the Dizziness Handicap Inventory (short version) before and after hearing aid fitting and usage will be compared

This community-based cross-sectional survey will estimate the frequency and risk factors of Chronic Suppurative Otitis Media and Hearing Impairment in Children ages 4-6 years in the Chikwawa District. These data will be useful for service planning, disease prevention efforts and to guide future research in this field.

Patients undergoing cochlear implantation after radio surgery for vestibular schwannoma will be included in the study. Patients will undergo preoperative and intraoperative eABR measurement. Correlations to postoperative hearing results will be drawn.

Hearing loss is one of the most common congenital anomalies . It has been shown to be greater than that of most other diseases and syndromes (eg, phenylketonuria, sickle cell disease) screened at birth. Data from the newborn hearing-screening programs in Rhode Island, Colorado, and Texas showed that 2-4 of every 1000 neonates have hearing loss. Early Intervention at or before 6 months of age allows a child with impaired hearing to develop normal speech and language, alongside his or her hearing peers and can prevent severe psychosocial, educational, and language impairment. One of the most high risk population are neonates who spend time in the newborn intensive care unit , exposed to high frequency ventilation, hyperbilirubinemia, low birth-weight, and exposed to ototoxic medications. Auditory brainstem response , otoacoustic emissions , and automated Auditory brainstem response testing have all been used in newborn hearing-screening programs. otoacoustic emissions are fast objective, efficient, and frequency-specific measurements of peripheral auditory sensitivity are used to assess response of the outer hair cells to acoustic stimuli. To measure otoacoustic emissions, a probe assembly is placed in the ear canal, tonal or click stimuli are delivered, and the otoacoustic emissions generated by the cochlea is measured with a microphone .

Evaluation of the outcome of cochlear implantation (CI) is very important issue since adequate hearing is linked to improved communication outcomes and school performance, development of speech and language, enhances speech perception in quiet and noise and even allows CI recipients to use the telephone. As well as there is a growing need for a widely used set of international quality standards on minimal outcome measurements to determine outcomes in CI recipients, monitor the auditory progress of CI recipients over time and to be able to relate on important issues as the most ideal age for implantation and the cut-off audiological thresholds for CI indication. This study will be conducted to evaluate outcome of cochlear implantation in sohag university hospital. Aim of work: To evaluate the outcome of cochlear implantation in Sohag university hospital.

The function of the vestibular system among patients with Sudden Sensori Neural Hearing Loss will be evaluted using the video Head Impulse Test

AUDICS-ICU is a prospective observational aiming to evaluate the prevalence of auditive dysfunction following cardiac surgery. Participants will undergo audiometric testings before and 3 months after cardiac surgery with cardiopulmonary bypass. Furthermore, the study evaluates hearing loss-associated ICU-acquired delirium after cardiac surgery with cardiopulmonary bypass.

SUSAC's Syndrome (SS) is characterized by the clinical triad of encephalopathy, hearing loss, and retinal artery branch occlusions. Since the first description of SS in 1979, hundreds of patients with SS, mostly young women, have been reported. However, comprehensive epidemiological, clinical and etiological features of SS have never been specifically addressed so far. The objective of this study is to characterize the epidemiological, clinical, and etiological features of SUSAC's Syndrome. In this aim, the investigators will constitute a national clinical-based cohort including all SS cases retrospectively reported in France since the last 20 years and all new cases prospectively observed. French Society of Neurology, Ophthalmology and Internal Medicine will be asked to collaborate. Every case will be reviewed by an expert comity of internists, neurologists and neuroradiologists to validate the diagnosis. The exhaustive and systematic analysis of each case will help to better define different aspects of the disease such as the incidence and prevalence, the clinical presentation, the diagnostic modalities and the impact of treatments. Diffusion tensor magnetic resonance imaging of the brain will be obtained to more carefully study the cerebral microvasculopathy of the disease. Serum, cerebrospinal fluid, and DNA samples from each patient will also be collected to study potential autoimmune, thrombotic and infectious markers.

To explore the genotype-phenotype correlation of SLC26A4 mutations in cochlear-implanted patients with enlarged vestibular aqueduct.
