Evaluation and Intervention for the Effects of Osteogenesis Imperfecta

We propose a longitudinal study of the natural history of types III and IV osteogenesis imperfecta for children age birth to 30 years. A consistent objective throughout this study is to obtain a comprehensive assessment of the natural history and progression of the multiple secondary features of osteogenesis imperfecta. In ...

Examination of Clinical and Laboratory Abnormalities in Patients With Defective DNA Repair: Xeroderma Pigmentosum Cockayne Syndrome or Trichothiodystrophy

Four rare genetic diseases, xeroderma pigmentosum (XP), Cockayne syndrome (CS), the XP/CS complex and trichothiodystrophy (TTD) have defective DNA excision repair although only XP has increased cancer susceptibility. We plan to perform careful clinical examination of selected patients with XP, XP/CS, CS, or TTD and follow their clinical course. We ...

Clinical and Genetic Analysis of Enlarged Vestibular Aqueducts

Nonsyndromic hereditary hearing impairment is a genetically heterogeneous disorder that can be caused by mutations in any one of at least 60 different genes. Enlargement of the vestibular aqueduct (EVA) is a radiologic finding known to be associated with mutations in one of these genes, the Pendred syndrome gene (SLC26A4, ...

Genetic Analysis of Hereditary Disorders of Hearing and Balance

Hereditary hearing impairment is a genetically heterogeneous disorder that can be caused by mutations in any one of hundreds of different genes. Approximately 20 genes have now been identified in which mutations can cause nonsyndromic sensorineural hearing loss. The identification and analysis of these genes and their mutations are providing ...

Investigation of Anatomical Correlates of Speech Discrimination

Understanding speech is essential for good communication. Individuals with hearing loss and poor speech discrimination often have little success with hearing aids because amplifying sound improves audibility, but not clarity of the speech signal. The purpose of this study is to determine the relative importance of the sensory cells of ...

Phase N/A

Evaluating Hearing Aid Service Delivery Models

The purpose of this study is to compare the outcomes for two different hearing-aid delivery models. In one model, the audiologist selects and fits the hearing aid and, in the other model, the consumer does this directly.

Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford

CoRDS collects contact, sociodemographic and health information about participants. This information is entered into CoRDS and linked to a unique coded identifier. Below are some examples of information requested on the Questionnaire that will be entered into CoRDS: - Contact information: Name, Mailing Address, Phone Number, Email Address - Sociodemographic ...

Phase N/A

Implantation of the HiRes90K Advantage Cochlear Implant With HiFocus Mid-Scala and Development of a Combined Electric and Acoustic Stimulation Technology in Adults With Partial Deafness

The purpose of this feasibility study is to evaluate whether low-frequency acoustic hearing sensitivity can be preserved in newly implanted adults with partial deafness (considerable low frequency acoustic hearing profiles with severe-to-profound high frequency sensorineural hearing loss) using the HiResolution™ 90K™ Advantage cochlear implant with the HiFocus™ Mid-Scala electrode to ...

Phase N/A

Cochlear Implantation in Cases of Single-Sided Deafness

Single-sided deafness (SSD) can be defined as moderate-to-profound sensorineural hearing loss with limited speech perception benefit in one ear and normal hearing in the contralateral ear. Though one ear is within the normal hearing limits, SSD may result in reduced speech perception in noise, variable abilities on localization tasks, increased ...

Kineret CAPS Post Authorisation Study

A non-interventional, post authorization safety study to evaluate the safety of Kineret in the treatment of Cryopyrin Associated Periodic Syndromes (CAPS) in routine clinical care with regard to serious infections, malignancies, injection site reactions, allergic reactions and medication errors, including re-use of syringe.
