In 1957 Landau and Kleffner described an unusual childhood disorder which they termed ‘syndrome of acquired aphasia with convulsive disorder’, in which language regresses after a period of normal development and seizures develop. Children with this disorder typically have severe receptive language difficulties and often are at first thought to be deaf. However, pure-tone audiometry shows normal...

Introduction Researchers studying the hearing health of forestry workers have revealed the presence of a noise-induced hearing loss (NIHL) in this population and have concluded that the vibration of the equipment, the carbon monoxide released by motors, and pesticides might also contribute to NIHL. Objective To analyze the noise exposure in the Brazilian forestry industry workers and the effect...

AIMS To characterise the development of noise induced damage to hearing. METHODS Hearing and noise exposure were prospectively monitored among a cohort of newly enrolled construction industry apprentices and a comparison group of graduate students, using standard pure tone audiometry and distortion product otoacoustic emissions (DPOAEs). A total of 328 subjects (632 ears) were monitored annua...

MATERIALS and METHODS: Cortical auditory evoked potentials were obtained from nine female and seven male patients with auditory neuropathy, ranging in age from 19 to 48 years. The control group comprised 15 (9 males and 6 females) age-matched, normally hearing adults. Cortical auditory evoked potentials were recorded in both groups. Audiological assessments were performed in both groups, which ...

Introduction Hearing loss is among the sensory changes strongly associated with loss of functional capacity. Objective It aims to determine whether the use of hearing aid contributes to the improvement of instrumental activities of daily living (IADL) for middle aged and elderly hearing-impaired individuals. Methods This is a descriptive, longitudinal, and interventional study. We evaluated 17 ...

OBJECTIVE Accessibility of audiometry is hindered by the cost of sound booths and shortage of hearing health personnel. This study investigated the validity of an automated mobile diagnostic audiometer with increased attenuation and real-time noise monitoring for clinical testing outside a sound booth. DESIGN Attenuation characteristics and reference ambient noise levels for the computer-base...

INTRODUCTION In our clinical experience, some of the patients affected by benign paroxysmal positional vertigo (BPPV) reported the onset of tinnitus shortly before or in association with the positional vertigo. OBJECTIVES The aim of this study was to describe the prevalence and the clinical patterns of tinnitus episodes which occurred in association with BPPV and to suggest possible interpret...
