Active clinical trials for "Deafness"

The aim of the research: Investigate the association of auditory evoked brainstem response characteristics with salivary cortisone concentrations in noise-exposed workers. Purpose of the research: Investigate the magnitude of the amplitudes and latencies of auditory brainstem responses. Investigate the concentration of cortisone in saliva. To investigate the correlation of the characteristics of auditory evoked brainstem potentials with the age of the subjects or the length of work in noise. Investigate the association of salivary cortisone concentration with subjects' age or length of work in noise. Investigate the prevalence of mild, moderate and severe hearing impairment in the 19-35 age group. Investigate the relationship of hearing threshold shift with the age of the subjects or the length of work in noise. To investigate the difference in the characteristics of auditory evoked brainstem potentials and the difference in salivary cortisone concentration between subjects with a bilaterally normal hearing threshold (≤25 dB) at high frequencies and subjects with unilaterally or bilaterally increased hearing threshold (> 25 dB) at high frequencies . Investigate the perceived stress and psychosocial risk factors in the workplace and their relationship to salivary cortisone concentrations. Research Hypothesis: There is an association between the characteristics of auditory evoked brainstem response and salivary cortisone concentrations in noise-exposed workers. Research participants Inclusion criteria: male and female ages 19-35 exposure to noise level ≥ 85 dB (A) per week at the workplace work in noise from 1 to 16 years workplace not involving exposure to carbon disulfide or a mixture of organic solvents that have toxic effects on the ear (toluene, xylene and styrene) unilaterally or bilaterally normal otoscopic findings unilaterally or bilaterally tympanogram: peak pressure value ± 50 daPa at 226 Hz with eardrum mobility of 0.3 to 1.3 mL Exclusion criteria: information about an earlier sudden hearing loss information on chronic middle ear inflammation information on ear surgery (except placement of ventilation tubes in the eardrum) information on dizziness associated with hearing loss and noise information on insomnia current use of oral corticosteroids bilaterally found air-bone gap greater than 15 dB

The cochlear implant is an electrical hearing aid that restores the perception of surrounding sounds and speech intelligibility in profoundly deaf patients. During surgery, the labyrinthine break necessary for insertion into the cochlea of the implantable part may cause a malfunction of the vestibular system which can induce dizziness, balance and perception (of the gravitational vertical) disorders. Vestibular compensation and new sonic interactions could alter the balance control and the visual and postural spatial orientation perceptions. The usual treatment includes the monitoring of the patient's quality of life, of the vestibular function and of hearing. This study adds an assessment of spatial orientation and of posture.

Mitochondrial diseases are multisystem disorders that present with a wide range of clinical manifestations. Mitochondrial DNA nt3243A>G mutation is one of the most common mutations seen in mitochondrial diseases. Syndromes associated with this mutation include mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), maternally inherited diabetes and deafness (MIDD), myoclonic epilepsy with ragged red fibers (MERRF), and chronic progressive external ophthalmoplegia (CPEO). Clinical analyses of mitochondrial DNA nt3243A>G mutation from Taiwan remain scarce. The present study aims to investigate the clinical features and prognostic factors of patients with mt3243A>G mutation in Taiwan.

This study aims to explore the determinants of cognitive impairment among Indonesian geriatrics in an Old Age Home.

Hearing impairment is common in older adults, and recent research points to associations between hearing impairment and balance/mobility. The association may be due to more attentional resources being used to compensate for the sensory loss, with less resources available for maintaining balance. The aim of this projects is therefore to investigate whether an exercise program with focus on motor-cognitive tasks is feasible for older adults with hearing impairment. The study is meant as a proof-of-concept study, where trialling will be evaluated, and results will be used to inform the design of a larger and adequately powered study.

Each year, approximately 15,000 people in the United Kingdom experience sudden loss of hearing that is sensorineural in nature. In the majority of cases, the cause is unknown despite investigation, and these cases are termed idiopathic 'sudden onset sensorineural hearing loss' (SSNHL). Treatment options for idiopathic SSNHL mainly include steroid treatments, with considerable limitations in their effectiveness and evidence base. There are a number of new treatments being developed for idiopathic SSNHL based upon recent discoveries in underlying molecular mechanisms. These treatments require rigorous testing in clinical trials before they can become available for clinical use. To allow for such trials to be run effectively, there is an urgent need for information on patient numbers, geographical distribution, demographics, patient and treatment pathways, as well as outcomes. This study proposes to collect these data through an ENT trainee and Audiologist led nationwide prospective cohort study of adult patients presenting with SSNHL within the National Health Services (NHS). The study will take place at 97 NHS sites across England with Ear, Nose, and Throat (ENT) and Audiology services. Data once collected will be analysed to: Establish the patient pathway for patients presenting with SSNHL in the NHS Develop a tool that will help predict recovery for patients with idiopathic SSNHL. Establish the impact of idiopathic SSNHL on people's quality of life.

The clinical use of genetic testing is expanding and, as a result, the number of variants identified in patients is growing. Knowledge of the clinical impact of these variants improves over time. However, the combination of more testing and the rapid evolution of genetic knowledge make it impossible for clinicians to fully account for the latest implications of their patients' genetic profiles as patient care decisions are made. This proposed study plans to enhance and evaluate IT infrastructure developed to provide timely genetic variant updates and patient search functionality to clinicians to assist in optimizing patient care.

The cochlear implant (CI) is the most important progress in the treatment for adults and children with severe to profound bilateral sensorineural hearing loss who do not receive adequa¬te benefit from hearing aids and making possible better results in auditory, linguistic, social and academic development.

All children with hearing loss should have access to resources necessary to reach their maximum potential. The following principles provide the foundation for effective EHDI[Early Hearing Detection & Intervention] systems and have been updated and expanded since the 2000 JCIH [ joint Committee on Infant Hearing ] position statement .

Cochlear implantation (CI) is a well-known surgical procedure to rehabilitate patients with severe to profound sensorineural hearing loss. Indications for this surgery have expanded in the last 10 years including bilateral CI. Although CI has been described as a safe procedure with few major complications, it may have an adverse effect on the vestibular functions and produce dizziness. Prevalence of postoperative dizziness varies widely in the literature and is said to affect between 2% - 47%.
