Filter by:Cisplatin is a widely used chemotherapeutic agent for the treatment of various malignant neoplasms, including testicular, ovarian, bladder, cervix uteri, head and neck and lung cancers. One of the common side-effects of this drug is bilateral, symmetric, progressive and usually irreversible sensorineural hearing loss. Cisplatin induces cochlear toxicity by the production of reactive oxygen species (ROS). Dexamethasone treatment is currently practiced for various pathologies afflicting the inner ear. The positive effect of Dexamethasone is attributed to it's anti ROS activity and it's capability to up-regulate cochlear anti ROS enzymes. In order to reach higher inner ear concentration of the drug while avoiding it's undesirable systemic side-effects, Intratympanic (IT) delivery of Dexamethasone became vastly used in the last decades for the treatment of sudden sensorineural hearing loss and Meniere's disease. Dexamethasone inserted IT, diffuse across the round window into the inner ear perilymph where it exerts its therapeutic effects. The investigators review of the literature yielded three animal studies which examined the protective effect of IT dexamethasone in the prevention of cisplatin-induced hearing loss. These studies demonstrated promising results pointing to the potential for IT dexamethasone in the prevention of cisplatin ototoxicity in humans. The purpose of this study is to examine possible protective effect of IT dexamethasone on cisplatin-induced hearing loss, in humans. The study hypothesis is that IT dexamethasone treatment would prevent cisplatin-induced hearing loss.
This study aimed to assess and reassess the balance and motor skills of deaf children, passed six weeks of intervention and to verify whether a program of physical therapy intervention can match or improve motor skills. This study was quasi-experimental before and after, with 10 children from a school in Caxias do Sul / RS. Motor skills were evaluated using pre and post test KTK Coordination Body, and the activities were held once a week for six weeks in sessions of forty minutes. It was used for statistical analysis the Student t test dependent and independent (p ≤ 0.05).
This prospective study is a randomized, double-blind, placebo-controlled Phase 3 clinical trial of oral D-methionine (D-met) to reduce noise-induced hearing loss (NIHL) and tinnitus. The goal of the study is to develop a safe, oral pharmacological agent to augment physical hearing protectors for noise exposures that exceed the protective capabilities of ear plugs and/or muffs. The study population is a cohort of Drill Sergeant (DS) instructor trainees during and 22 days after their 11 day weapons training. The primary objective of this study is to determine the efficacy of D-met in preventing NIHL or reducing tinnitus secondary to a minimum of 500 rounds of M-16 weapons training occurring over an 11 day period.
The objectives of this study are: 1. To see if autologous human umbilical cord blood treatment is safe for children with acquired hearing loss, and 2. To determine if late functional outcome is improved following autologous human umbilical cord blood treatment for children with acquired hearing loss.
Many authors link tinnitus to arterial hypertension. The aim of this study is to establish a possible relationship between them, analyze the severity of tinnitus related to arterial hypertension and analyze a possible influence of ototoxic drugs used to treat arterial hypertension
The purpose of this study is to determine if Anakinra (an interleukin-1 receptor antagonist) can improve hearing thresholds in those patients with Autoimmune Inner Ear Disease (AIED) that did not respond to oral steroid therapy for a sudden decline in hearing. The patients to be enrolled will have recently completed a course of oral steroids and demonstrated no change in their audiometric thresholds following corticosteroid therapy.
The aim of the study is to assess the effect of antiviral therapy with pegylated interferon alpha for hepatitis C and B on auditory disability as there are reports in the English literature on auditory disability caused by interferon alpha.
A bone-anchored hearing aid (Baha) consists of a titanium implant located at the mastoid, and a sound processor connected with the implant. The sound processor delivers bone conducted stimuli to the cochlea, bypassing the outer and middle ear. Some patients who are unable to wear or do not benefit from a conventional air-conduction hearing aid, are candidate for a Baha. Typically, these patients suffer from a conductive or a mixed hearing loss. Recently however, Baha's are also being recommended in patients with unilateral deafness. Sound coming from the deaf side is captured and transmitted through bone conduction to the normal inner ear. The overall benefit of a Baha is more difficult to assess in those patients. Therefore, the goal of the current study is to examine the benefit of a Baha in patients with different audiological profiles (unilateral or bilateral conductive or mixed hearing loss, and unilateral deafness). Special attention will be given to predictive determinants of the benefit with a Baha, and to the improvement of pre-operative criteria and counseling of patients.
Purpose: to investigate the relationship between time for treatment seeking and audiometric data and self-assessment of handicap for patients in a public hearing healthcare service. Methods: Retrospective study. Records of 152 elderly and 48 adults with hearing impairment were analyzed. The ISO audiometric thresholds average (500 to 4000Hz) and high frequencies average (2000 to 6000Hz), the speech recognition thresholds and the total, social and emotional scores from the Hearing Handicap Inventory for the Adults (HHIA) and Elderly (HHIE) were compared with the time between the onset of hearing complaints and the first treatment seeking. Results: The average time for treatment seeking was 7,6 years. No statistical difference was found between ISO and high frequency audiometric average, HHIA/E scores and time for treatment seeking between adults and the elderly. Weak but significant negative correlations were observed between the audiometric data and time for treatment seeking. There was no relationship between the time for treatment seeking and educational, socioeconomic levels and perception of handicap. Conclusions: The search for treatment seems to be multifactorial. Despite technological advances and changes in access to information and treatment time for treatment seeking was similar to that reported 30 years ago.
Children with special needs require complex, individualized therapy to maximize their long-term quality of life. One subset of children with special needs includes those with both developmental delays and deafness. Currently, there is little compelling evidence supporting the idea that cochlear implantation provides benefit to children that don't have the cognitive potential to develop normal speech and language. We will perform a prospective, randomized clinical trial to answer the question of which intervention provides more benefit to this population of children using validated, norm-referenced tests. Our long-term goal is to develop guidelines that may help when selecting a treatment for hearing loss in a child with developmental delays. This proposal is significant because children with special needs are deserving of evidence upon which to base treatment decision-making, but remain under-represented in the medical literature and are often not studied. This research is designed to meet the criteria for the National Institutes of Health road map because it will generate this type of objective evidence that can directly improve patient care.
