Filter by:The purpose of this study is to find out how often hearing loss occurs in patients with retinoblastoma after receiving treatment with intra-arterial carboplatin.
The purpose of this study is to see how the inner ear responds to sound delivered to the ear canal during and after your cochlear implant surgery. This information may be helpful in telling us how well a cochlear implant performs after surgery.
This study aims to explore the determinants of cognitive impairment among Indonesian geriatrics in an Old Age Home.
Hearing loss is among the top service-connected disabilities in Veterans. Hearing aids are the primary intervention for hearing loss. Half of the hearing aids dispensed in the VA are to Veterans who are receiving replacement amplification. Many Veterans would like their replacement hearing aids mailed to them, but they are required to travel to the clinic so that the fit of the hearing aid can be verified. There are standard fitting procedures, such as those used in infants and children, that use a coupler to simulate the patient's real ear to verify the hearing aid fitting. The results of this study should determine the efficacy of a coupler-based hearing-aid fitting protocol that would not require the Veteran to attend the fitting appointment, thereby contributing to improved Veteran-Centric care.
Hearing impairment is the most frequent sensory deficit in humans and affects one newborn out of 500. The prevalence rises to 3,5/1000 in teenagers due to retarded forms. Most of hearing impairments (about two thirds) have a genetic origin, with recessive, dominant or X-linked mode of inheritance. Some rare forms can be linked to mitochondrial DNA. Molecular diagnosis (i.e. defining the molecular basis of the disease, genes and precise DNA variants) is essential for the follow-up of patients and families. The project intends to perform exome sequencing on 30 samples of families presenting with hearing impairment. Families have been included based on the genetic origin of the hearing impairment (familial cases) and the exclusion of the involvement of 74 known deafness genes. Exome sequencing (sequencing of the coding regions of all known genes, about 22,000) in these cases may underly new gene/disease relationships.
Purpose: Routine clinical care and pilot study data has shown evidence of postoperative hearing preservation in pediatric cochlear implant (CI) recipients. The primary aim of this study is to investigate speech perception performance in pediatric CI recipients with functional pre-operative hearing. Participants: Two cohorts of CI recipients aged 6 through 17 years who had pre-operative low frequency residual hearing. Subjects in Arm 1 will present with a post-operative low frequency pure tone average (125, 250, and 500 Hz) of ≤ 75 dB HL, and those in Arm 2 will present with a post-operative low frequency pure tone average (LFPTA) that exceeds 75 dB HL. Procedures (methods): Subjects will complete speech perception and quality of life testing during post-operative intervals. Subjects in Arm 1 will be evaluated with the hearing aid alone (HA-alone) and with combined electric-acoustic stimulation (EAS). Subjects in Arm 2 will be evaluated with the CI-alone.
Bilateral severe to profound hearing loss is a socially disabling handicap. Cochlear implants can be used to improve hearing in cases where conventional hearing aids are not effective. There are few studies about the long latency Auditory Evoked Potential (P300), in individuals with hearing loss and Cochlear Implant (CI) users. The aim of this project is to study the behavior of P300 in users of unilateral CI.
The purpose of this study is to test the effectiveness of a community health worker intervention to expand access to hearing health care among older adults facing health disparities.
The overall goal of this study is to determine the clinical benefit and safety of antiviral therapy for asymptomatic congenital cytomegalovirus (cCMV) infected hearing-impaired infants. We will conduct a multi-center double-blind randomized placebo-controlled trial to determine whether hearing-impaired infants with asymptomatic cCMV have better hearing and language outcomes if they receive valganciclovir antiviral treatment. We will also determine the safety of antiviral valganciclovir therapy for asymptomatic cCMV-infected hearing impaired infants. This study will be unique in that the cohort enrolled will only include hearing-impaired infants with asymptomatic cCMV. Primary Objective: To determine if treatment of cCMV-infected hearing impaired infants with isolated hearing loss with the antiviral drug valganciclovir reduces the mean slope of total hearing thresholds over the 20 months after randomization compared to untreated cCMV-infected infants with isolated hearing loss. Main Secondary Objectives: 1. To determine if valganciclovir treatment improves the following outcomes when compared to the control group: 1. The slope of best ear hearing thresholds over the 20 months after randomization. 2. The MacArthur-Bates Communicative Development Inventory (CDI) percentile score for words produced at 20 months of age. 2. To evaluate safety measures based on all grade 3 or greater new adverse events designated by the NIAID Division of AIDS (DAIDS) toxicity tables.
The purpose of this investigation is to determine the safety and preliminary efficacy of implanting a cochlear implant (CI) in the profoundly deaf ear of an adult with one normal hearing (NH) ear (termed "single-sided deaf" person, or SSD). The potential subjects will have been deafened post-lingually, thus, at one point the now deafened ear did conduct sound from the periphery. The MED-EL CI system will be implanted in ten (10) SSD patients.The long-term goal of this research program is to determine whether the CI, in combination with the NH ear, may provide improved localization ability and better speech understanding in noise, relative to performance before cochlear implantation (i.e., with the NH ear alone). A secondary long-term goal is to determine whether CI stimulation may reduce tinnitus severity, compared to tinnitus experienced prior to cochlear implantation or when the CI is turned off, after implantation.
