With distance learning becoming more of a reality than a novelty in many undergraduate and graduate training programs, web-based clinical simulations can be identified as an instructional option in distance education that has both a sound pedagogical foundation and clinical relevance. The purpose of this article is to report on the instructional effectiveness of a web-based pure-tone audiometry...

UNLABELLED Noise level can be quantified and qualified based on sound characteristics such as intensity, type of spectrum, duration and distribution of the noise exposure during one's working hours. OBJECTIVE To assess noise spectrum and the audiometric configuration of workers. MATERIALS AND METHODS Contemporary cross-sectional cohort carried out in the Federal District - Brazil. We did an...

A retrospective analysis to quantify age-related changes of the incudo-malleolar joint (IMJ) and incudo-stapedial (ISJ), analyse in air-bone gap (ABG) with age, was performed. Defined histologic parameters 153 IMJ 106 ISJ from subjects aged birth 70 years were correlated age. Additionally, audiograms 1760 ears 974 other 20 80 retrospectively analysed ABG The space (age group 0 10 compared 61 ye...

OBJECTIVE Occupational noise exposure and noise-induced hearing loss (NIHL) among construction workers has long been recognized as a problem in the United States, yet little is known about the prevalence of NIHL among American construction workers. The purpose of this study was to determine the prevalence and characteristics of hearing loss among operating engineers (OEs) who operate heavy cons...

Traditional classroom techniques lacking the advantages offered by multimedia demonstrations often fall short of the goal of furnishing the students with an adequate “ears-on” awareness of the problems of the hearingimpaired. As a first step towards virtual hearing impairment, a CD-ROM with speech material simulating a selection of common types of hearing impairment was produced. The material w...

Noise-induced hearing loss (NIHL) continues to be one of the most prevalent occupational conditions and occurs across a wide spectrum of industries. Occupational hearing loss is preventable through a hierarchy of controls, which prioritize the use of engineering controls over administrative controls and personal protective equipment. The occupational and environmental medicine (OEM) physician w...

RA (rheumatoid arthritis) is a chronic multisystem disease with a variety of systemic manifestations. One of these manifestations, is hearing disorder, so study of the relation between RA and hearing disorders is seem important. This was a case-control study which has done from December 2004 to August 2006. This study compared 50 patients with RA, with age, sex and job-matched as control. Audio...

introduction: although the incidence and prevalence of chronic suppurative otitis media (csom) has been decreased in recent decades, but it is still a major health problem in both developing and developed countries. csom can cause major and life-threatening complications such as hearing loss, meningitis and cerebral abscess. since hearing loss is the most common complication of csom, we aimed t...
