NCT ID: NCT03599804 Not yet recruiting - Clinical trials for Vestibular Abnormality

Vestibular Cochlear Implant Hearing Impaired Child

Start date: June 2019
Phase:
Study type: Observational

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%.

Objective Measures in Cochlear Implant

Start date: December 1, 2017
Phase: N/A
Study type: Observational

One of the main factors affecting the ability to maximize the full potential of a cochlear implant is an accurate map.The goal of mapping is to enable cochlear implant recipients to perceive a desired range of acoustic signals. The process includes programming of the minimum and the maximum stimulation levels that are based on subjective measurements of thresholds and the most comfortable level . The use of objective measures in the CI process has greatly contributed to the definition of the dynamic field, as they provide specific values that serve as the basis for the start of the mapping process, especially in cases of infants and young children. Some examples of these measures are electrically evoked stapedius reflex threshold , neural response telemetry , brainstem auditory evoked potential , and P300, among others.

NCT ID: NCT03251638 Not yet recruiting - Clinical trials for Neonatal Hearing Impairment

Neonatal Hearing Screening in Assiut Hospital

Start date: March 2018
Phase: N/A
Study type: Observational

Hearing loss is one of the most common congenital anomalies. Early Intervention at or before 6 months of age allows a child with impaired hearing to develop normal speech and language.Auditory brainstem response , otoacoustic emissions testing have all been used in newborn hearing-screening programs

Body Mass Index and Audiology Function

Start date: May 1, 2018
Phase: N/A
Study type: Interventional

Obesity may directly or indirectly lead to hearing loss

NCT ID: NCT03142100 Not yet recruiting - Hearing Loss Clinical Trials

Combined Acoustic and Electric Hearing (CI/HA) in Adult Bimodal Users Using a HA With a Bimodal Fitting Formula

Start date: June 15, 2017
Phase: N/A
Study type: Observational

Introduction: Bilateral-bimodal users may benefit from bilateral-binaural and a bimodal effect . The two modes of stimulation complement each other and may overcome the limitation of electric hearing alone. However, alongside the expected benefits of having two hearing systems in bilateral bimodal hearing, there are several inherent mismatches in combing two different stimulation methods, which may negatively impact the processing of the binaural cues. Aim: To determine whether bimodal listening with a hearing aid programmed using a dedicated bimodal fitting formula, which aligns the frequency response, loudness growth functions, and automatic gain control (AGC) characteristics between the cochlear implant speech processor and the hearing aid brings additional benefit over bimodal listening with the subject's clinical hearing instrument via the use of using a comprehensive battery of speech perception tests aimed at different aspects of binaural hearing as well as the contribution of the unique bimodal complementary effect. A secondary goal is to identify the tests that are best suited to predicting and evaluating bimodal benefit. Method: The study will include 20 Hebrew and 20 Arabic speakers' adult bilateral-bimodal users that their audiometric thresholds in the non implanted ear will be no worse than 75 dB HL at 250 and 85 dB HL at 500 Hz, who use their hearing aids for at least 75% of their waking hours. The added benefit of the hearing aid programmed using a dedicated bimodal fitting formula will be evaluated using six task-specific tests designed to sensitively assess the bilateral-binaural and bimodal complementary effects using roving speech and noise and different types of background noises (maskers), pitch-related task and subjective questionnaire. Participants will be tested twice in quick succession, at two-weekly intervals, in establishing a baseline score with their clinical HAs. Then participants will be tested again twice in quick succession, at two-weekly intervals following three month experience with the HA fitted with the bimodal fitting formula. All tests will be administered the CI/HA listening condition.

NCT ID: NCT03101917 Not yet recruiting - Clinical trials for Hearing Loss, Cochlear

Microtable® Method for Cochlear Implantation Investigational Device Exemption (IDE)

Start date: July 1, 2024
Phase: N/A
Study type: Interventional

The Microtable® Microstereotactic Frame and Drill Press and Associated Method for Cochlear Implantation consists of a patient-customized microstereotactic frame which targets the cochlea. The intended use of the device in this early feasibility study is to surgically access the cochlea, allowing placement of an intra-cochlear electrode array for cochlear implantation, thereby providing a less invasive surgical option than currently performed. Compared to traditional cochlear implantation (CI) surgery, the investigators hypothesize that the minimally invasive, image-guided approach may offer the following benefits: (1) shorter procedure time including shorter general anesthesia time, (2) less tissue removal potentially eliminating post-operative mastoid bone depression, decreased post-operative patient discomfort, and quicker wound healing, (3) better chance of preservation of taste secondary to preservation of the chorda tympani nerve, and (4) standardization of electrode placement potentially allowing more consistent placement within the scala tympani sub-compartment of the cochlea which has been shown to be associated with improved post-operative audiological performance. This early feasibility study will focus on the advantages of the new technology to the patient. Advantages to the healthcare delivery system will be examined during the pivotal study phase.

NCT ID: NCT02882477 Not yet recruiting - Diabetes Mellitus Clinical Trials

Treatment of Wolfram Syndrome Type 2 With the Chelator Deferiprone and Incretin Based Therapy

Start date: December 2016
Phase: Phase 2/Phase 3
Study type: Interventional

Patients who are genetically diagnosed with the recently reported and rare Wolfram syndrome type 2 ( WFS2) and have the degenerative and symptomatic disease including signs such as diabetes, platelet aggregation defect or visual problems will be asked to participate in this study. Knowing the pathomechanism of WFS2 with rapid cell death, after doing baseline investigations to asses the severity of their disease, the participants will be offered a chelator therapy with in addition to the antioxidant Acetylcystein, in diabetic patients an Incertin (GLP-1 ) therapy will be offered as well. The baseline investigations will be repeated after 2 months and after 5 months of therapy in order to asses the progression of the disease and to show if the chelator and anti oxidant therapy and in diabetic patients the GLP-1 therapy could stop the progression of the disease.

NCT ID: NCT02779192 Not yet recruiting - Clinical trials for Noise Induced Hearing Loss

A Phase 2b Study of SPI-1005 to Prevent Acute Noise Induced Hearing Loss

PANIHL
Start date: November 2018
Phase: Phase 2
Study type: Interventional

SPI-1005 is a novel oral drug that contains a glutathione peroxidase mimetic (ebselen) that will be tested in subjects with a history of NIHL at risk for additional NIHL. The goal of this multi-center Phase 2b study is to determine whether SPI-1005 is effective in reducing an acute NIHL in this affected population. In this Phase 2b study subjects with prior NIHL will be enrolled and exposed to a calibrated sound challenge (CSC) that induces a slight acute NIHL.
