Active clinical trials for "Deafness"

Cochlear implantation enables profoundly deaf children to acquire speech and develop their understanding of spoken language. However, there are significant interindividual differences in the results obtained with the implant. Given the lack of theoretical knowledge on acoustic predictors, cognitive and language to obtain optimum speech recognition with cochlear implants associated with a good communicative and language development of deaf children, the investigators intend to achieve a preliminary longitudinal study aimed to describe the cognitive, communicative and perceptive implanted deaf children. The main objective of our study is to describe the cognitive and communicative development of deaf children implanted from the pre-implant assessment to 18 months post-implantation, by addressing the following aspects: The psychomotor and cognitive development assessed using the Brunet-Lézine test; The development of preverbal communication, evaluated using the Early Social Communication Scale.

The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing loss.

Do adults and children over 7 years of age with unilateral or assymetric hearing loss benefit from cochlear implantation on the worst hearing side.

To prospectively examine the relations between adherence scores for three healthful dietary patterns, the Alternate Mediterranean diet (AMED), the Dietary Approaches to Stop Hypertension (DASH), and the Alternative Healthy Eating Index (AHEI-2010), and risk of hearing loss in the Nurses' Health Study II.

To compare the audiological profiles in postmenopausal women with and without osteoporosis and to examine the pattern of hearing loss in osteoporotic patients. postmenopausal women will be separated as normal, osteopenic and osteoporotic according to bone mineral densitometry results. The evaluation of hearing test will be done in these groups and the results will be compared between the groups.

The purpose of this study is to understand the speech perception in noise and in quiet and localization benefits in a laboratory setting in listeners that receive a cochlear implant in an ear with severe to profound hearing loss and have normal, or near-normal hearing in the opposite ear. We will also evaluate the functional benefit of restoring hearing to the impaired ear via questionnaires that subjects will be answering while listening in their natural environment.

This Doctor of Philosophy (PhD) project is part of a larger project on potentially modifiable risk factors for dementia in a life course perspective, with an overarching aim to improve prevention of dementia and thereby potentially relieve patient and caregiver distress and decrease societal load. The present PhD project will concentrate on confirming knowledge of HI as an independent risk factor for dementia and exploring potentially causative factors to explain this relationship.

Nowadays in France, there is no organized screening of the hearing loss in the elderly; however, it is a very common disease and simples tests to perform to detect it exist. Lots of studies use surveys to identify deaf people; but physicians often consider them too sensitive and less specific because lots of people were classified into " deaf " people meanwhile they have a subnormal tonal audiogram. Now, it's known that it corresponds to the "Hidden Hearing Loss" concept: it's defined as an auditive disturbance in a noisy ambiance in people with a normal tonal audiometry; corresponding to infraclinical cochlear lesions. These lesions, if detected early, can be prevented to avoid an audition degradation in time. The aim of the study is to determinate the values of sensitivity and specificity of the HHIE-S survey translated into French, so it could be used as a screening method of hearing loss in the elderly and as a prevention of cochlear damages.

This study aims to understand how to manipulate the electrical stimulation from the cochlear implant to maximize hearing stimulation and minimize facial stimulation. It is know from animal data that the hearing and facial nerves have different sensitivities to things like electrical pulse shape, its pattern, and its duration. It is very unclear however if this applies to human cochlear implant patients, and what the optimal parameters are to selectively stimulate the hearing nerve in humans. The outcomes of this study will be used to more selectively program some patients with severe facial nerve cross stimulation and to inform the development of new types of implant stimulation.

Objectives: To assess a group of post-lingually children after 10 years of implantation with regard to speech perception, speech intelligibility, and academic/occupational status. Study Design: A prospective transversal study. Setting: Pediatric referral center for cochlear implantation. Patients: Ten post-lingually deafened children with Nucleus and Med-El cochlear implants. Interventions: Speech perception and speech intelligibility tests and interview. Main Outcome Measures: The main outcome measures were score of Hint sentences recognition (silence and noise), speech intelligibility scores(write-down intelligibility and rating scale scores) and academic/ occupational status.
