Culturing otospheres from dissociated organ of Corti is an appropriate starting point aiming at the development of cell therapy for hair cell loss. Although guinea pigs have been widely used as an excellent experimental model for studying the biology of the inner ear, the mouse cochlea has been more suitable for yielding otospheres in vitro. The aim of this(More)
We ascertained a Brazilian family with nine individuals affected by autosomal dominant nonsyndromic sensorineural hearing loss. The bilateral hearing loss affected mainly mid-high frequencies, was apparently stable with an early onset. Microsatellites close to the DFNA8/DFNA12 locus, which harbors the TECTA gene, showed significant multipoint lod scores(More)
In 20% of cases, hereditary non-syndromic hearing loss has an autosomal dominant inheritance (ADNSHL). To date, more than 50 loci for ADNSHL have been mapped to different chromosomal regions. In order to verify whether genomic alterations contribute to the hearing loss etiology and to search for novel deafness candidate loci, we investigated probands from(More)
INTRODUCTION The public and private health care in the city of São Paulo has no data on tinnitus prevalence. OBJECTIVE Determine tinnitus prevalence in São Paulo city. STUDY DESIGN Series study. METHODS Cross-sectional study by field questionnaire with 1960 interviews. Predictor variables included gender, age, tinnitus. RESULTS The prevalence of(More)
UNLABELLED The epidemiology of dizziness is essential in clinical practice. OBJECTIVE To establish the prevalence of dizziness in the adult population of São Paulo, its clinical characteristics and level of discomfort. METHOD A prospective cross-sectional study ran from April to October of 2012 by a field questionnaire, totaling 1,960 interviews. The(More)
Introduction Tinnitus is an abnormal perception of sound in the absence of an external stimulus. Chronic tinnitus usually has a high impact in many aspects of patients' lives, such as emotional stress, sleep disturbance, concentration difficulties, and so on. These strong reactions are usually attributed to central nervous system involvement. Neuroimaging(More)
Sudden hearing loss is defined as a sensorineural hearing loss, equal to or greater than 30 dB, at three or more consecutive frequencies, which takes place within 72 hours. Both peginterferon and ribavirin are well-known to be associated with significant adverse effects, but sudden hearing loss is uncommon. We report a 65-year-old male patient who developed(More)
The aim of this study was to determine the effects of various treatment modalities employed for patients with sudden sensorineural hearing loss (SHL). We retrospectively evaluated the records of patients treated in the sudden hearing loss section of the Otolaryngology Department at Clinic Hospital, School of Medicine, University of São Paulo, Brazil,(More)
In mammals, damage to sensory receptor cells (hair cells) of the inner ear results in permanent sensorineural hearing loss. Here, we investigated whether postnatal mouse inner ear progenitor/stem cells (mIESCs) are viable after transplantation into the basal turns of neomycin-injured guinea pig cochleas. We also examined the effects of mIESC transplantation(More)
