Filter by:Osteogenesis Imperfecta-related hearing loss usually occurs in individuals with mild (type I) OI and is much earlier in onset than age-related hearing loss, with the majority of individuals experiencing some minor hearing loss in their 20s. Bisphosphonates have been successfully used to treat otosclerosis, a common cause of hearing loss similar to OI-related hearing loss. As many individuals with OI-related hearing loss also present with otosclerosis and because of their mechanistic similarities, the investigators propose studying the effects of bisphosphonate treatment on individuals diagnosed with both OI type I and hearing loss, thereby determining its effectiveness as a potential treatment for hearing loss. The investigators will enroll 50 individuals diagnosed with type I OI and age 18-100. 25 adults will be enrolled into the treatment arm and receive bisphosphonate treatment (must have at least mild hearing loss), while 25 adults will be enrolled into the control arm. The investigators will enroll 25 children (6-17 years of age) diagnosed with OI who are currently receiving bisphosphonate treatment as part of their care for orthopedic symptoms. The investigators will also observe 25 children (6-17 years of age) diagnosed with OI who are NOT currently receiving bisphosphonate treatment. The study duration is 63 months (approximately 5 years). Enrollment is anticipated to begin in November 2019.
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: 1. Establish the patient pathway for patients presenting with SSNHL in the NHS 2. Develop a tool that will help predict recovery for patients with idiopathic SSNHL. 3. Establish the impact of idiopathic SSNHL on people's quality of life.
Over the last few decades, the classical two-stage surgical procedure for inserting bone-anchored hearing implants (BAHIs) has been modified in adults into a single-stage procedure. This approach has several advantages since it avoids a second surgical procedure. The single-stage approach is proven to be safe and feasible in adults and is nowadays referred to as the standard surgical technique in adults. Despite favorable outcomes and advantages of the single-stage surgery, most Ear Nose Throat (ENT) surgeons still perform two-stage surgery when inserting BAHI in the pediatric population. Therefore, the aim of this study is to compare implant loss between single-stage BAHI surgery and two-stage BAHI surgery in children aged 4 to 9 years.

This R56 award will address questions pertaining to the feasibility of the Sit Together and Read (STAR) intervention for children with hearing loss (HL). Evidence suggests that STAR, a caregiver-implemented early literacy intervention, imparts positive effects on print knowledge gains and later reading outcomes for children at risk for reading difficulties, such as those with language impairment and those living in poverty. To date there are no large-scale studies examining literacy interventions for children with HL, who are also known to be at risk for reading disorders. However, prior to engaging in a large-scale study, this research will establish preliminary feasibility and efficacy data for this specific population who will likely benefit from a evidence-based, manualized intervention. In addition to collecting pilot data regarding the feasibility and efficacy of this intervention for children with HL, this study will also determine barriers and challenges experienced by caregivers of children with HL in implementing the intervention. As such, this study will also yield important information regarding adaptations of the existing STAR intervention that may be required for successful and effective implementation for children with HL, and can be incorporated into future submissions.
In search of the best possible outcome for the severe hearing impaired who have regained the ability to hear by means of a cochlear implant (CI), electrical stimulation and the information it carries should match as closely as possible to what the human brain naturally has evolved to cope with and learned to process instead of relying on plasticity to adapt to an induced mismatch. At the moment, however, CI's are fitted with a 'one size fits all' principle. This is known to cause a mismatch between the frequencies presented by the CI electrode array and the frequencies represented at the corresponding natural acoustic location in an individual cochlea. In this study it is hypothesized that an individual imaged based fitting that pursues natural hearing alignment and is implemented from the start of the rehabilitation process, will improve the individual outcomes of electric hearing. The natural fitting strategy is thought to give rise to a steeper learning curve, result in a better performance in challenging listening situations, improve sound quality, complement better with residual acoustic hearing in the contralateral ear and win the preference of CI-recipients.
Improving spoken language outcomes for children with hearing loss has important public health implications. This is a randomized clinical trial of 96 children with hearing loss that examines the effects of a parent-implemented early communication intervention on prelinguistic and spoken language outcomes. The study is open for national recruitment. Parents participate via video call with their child and receive technology to assist with virtual visits.
Study on patients with CNS infections.
This thesis project proposes to investigate the "state of the art" of the programming of the cochlear implant. In the center of audiophonologie Brussels, the classic 'manual programming' has been in use over 20 years and also the new way 'Artificial Intelligence programming'. The investigators want to compare, objectify, and control this new mode of programming. The study is planned over 4 years, in order to test, randomized, 15 subjects with manual programming and 15 other subjects with Artificial Intelligence programming. To test the performance of Cochlear Implant patients, audiological, language auditory perception and questionnaire tests will be presented. This research aims to determine the contribution and results of Artificial Intelligence programming.
This descriptive and observational research project aims to characterize MMN as a neuronal marker of localization deficit in single-sided deafened subjects and subjects with bilateral profound deafness treated by a cochlear implant (CI). It includes several electro-physiological and psychoacoustic assessments performed on subjects with single-sided deafness and cochlear implanted subjects, with normal-hearing subjects as control: - Evaluation of the characteristics of the MMN involved in sound localization by EEG. - Evaluation of the spatial localization abilities for a sound source presented in the open field. - Assessment of performance for speech recognition in noise. These evaluations are performed in subjects with symmetrical hearing, in a natural binaural condition and a monaural condition (with a plugged ear), in subjects with single-sided deafness and in subjects with unilateral CI
