Filter by:The ability to encode the speech signal is determined by ascending and descending auditory processing. Difficulties in processing these speech signals are well described at the behavioral level in a specific language disorder. However, little is known about the underlying pathophysiological mechanisms. The assumption is that we should observe a degradation of the signal provided by the ear in the deaf subject while in case of specific language impairment it would be a phonemic disorder (possibly linked to a processing disorder auditory). The two population groups should therefore have different abnormalities of their central auditory process - which could be modified by the target remediation for each group.
The purpose of this research study is to test the effectiveness and safety of the study drug, AM-111. AM-111 is tested for the treatment of sudden sensorineural hearing loss where the cause is unknown.
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 objective is to study the relation between the reorganization of the central auditory system, and the psychophysical deficits in binaural hearing in subjects with single sided deafness.
This is a research study to determine whether a cochlear implantation (CI) device can improve hearing in people who are deaf in one ear (known as single-sided deafness).
Single sided deafness (SSD) refers to asymmetrical hearing loss, where there is a significant worsening of hearing in one ear compared to the other. In Cambridge, the investigators see large numbers of patients with SSD caused by vestibular schwannomas, due to their affiliation with the Neuro-Otology Department, with over 100 new SSD patients being referred every year. Only a small number of studies have explored hearing handicap for those with SSD, and music appreciation has not been investigated, to the best of the investigators knowledge, in this patient group. In the limited number of studies conducted on those with single sided deafness, often only one or two outcome measures have been used, or the patient group has been small. The investigators have a large group of patients with a wide range of aetiologies who have completed several questionnaires as part of their treatment in the single sided deafness clinic and the investigators would like to analyse these data. At present there are different devices available on the NHS for the management of SSD and many studies have explored benefits of Bone Anchored Hearing Aids (BAHA). There is an under-representation of studies looking specifically at CROS aid devices which is relevant given the cost differences involved between devices. Study goals and objectives - To find out what factors drive hearing handicap in SSD patients by analysing the results of several different well validated hearing handicap questionnaires - To find out whether or not it is possible to change hearing handicap in this patient group by looking to see if there is an improvement in questionnaire scores post treatment. - The investigators will also look at a sub-group who will be fitted with both traditional wired CROS aids and more up-to-date wireless aids which have been funded through a research grant, in order to assess whether these are more beneficial. - The investigators will use a new questionnaire developed in-house to further explore the impact of single sided deafness on music appreciation.
This study will assess the effectiveness of post-cochlear implant or hearing aid fitting Aural Rehabilitative Therapy (ART) delivered by means of telemedicine technology.
To the investigators' knowledge, no clinical study has prospectively investigated the relationship between surgical insertion technique, intracochlear electrode location, and postoperative hearing outcomes. To this end, the investigators are conducting a multicenter prospective randomized controlled double-blinded study comparing round window and cochleostomy cochlear implant electrode insertion.
The objective of this study is to make a comparison between two surgical techniques used when implanting a Ponto bone anchored hearing system.
A limited number of relatively contradictory studies have suggested that the development of serious ototoxicity in children treated with cisplatin or, more rarely, carboplatin could be partly related to genetic risk factors affecting detoxification enzymes and membrane transporters of platinum derivatives. The objective of this study is therefore to identify genetic variants associated with the development of platinum ototoxicity in patients treated with cisplatin or carboplatin (minimum follow-up of 3 years) for one of the following diseases: neuroblastoma, hepatoblastoma, retinoblastoma, malignant germ cell tumour, osteosarcoma, high-risk or recurrent Wilms' tumour, non-parameningealrhabdomyosarcoma. A total of 180 patients, corresponding to 60 cases with grade 3 or 4 ototoxicity and 120 controls with no signs of ototoxicity (separate complete audiograms for each ear) will be included. A saliva sample will be used to obtain DNA for pharmacogenetic studies. The value of this study will be to define a population at high risk of developing ototoxicity in order to adapt treatment, or even develop preventive treatment of ototoxicity based on antioxidant medications
