background: noise-induced hearing loss (nihl) is a common, irreversible occupational disease. statins have recently been proposed to prevent nihl. objective: to assess the effect of atorvastatin for the prevention of nihl in rats. methods: in this experimental study, forty 2–3-month-old wistar male rats were divided into 5 groups of 8 animals. 3 groups of rats received atorvastatin at doses of ...

Background and aims: Many workers face significant hazardous workplace exposures, especially indeveloping countries. The objective of this study was to investigate the prevalence of occupational riskfactors and common occupational diseases in Kerman.Methods: This study was based on data from occupational risk factor and disease monitoring systemsavailable at Kerman Provi...

OBJECTIVES This cross-sectional study was performed in the Dental School of Prince of Songkla University to ascertain noise exposure of dentists, dental assistants, and laboratory technicians. A noise spectral analysis was taken to illustrate the spectra of dental devices. METHODS A noise evaluation was performed to measure the noise level at dental clinics and one dental laboratory from May ...

BACKGROUND There are no data on the prevalence of occupational noise-induced hearing loss in drivers using standard audiometric testing. The aim of this study was to estimate the prevalence and risk factors of occupational noise-induced hearing loss in drivers. METHODS A cross-sectional study was conducted on a random sample of 4300 long-distance drivers age > or =20 years taken out of a tota...

a randomized cross sectional epidemiologic study about the occupational health problems of hairdressers was conducted in tehran in 1988. the sample selected for survey consisted of 200 women and 398 men- study findings indicated that the working hours were often irregular and overtime. evaluation of working conditions showed that the female hairdressers were more exposed to noise than male. the...

Problem statement: Noise Induced Hearing Loss (NIHL) is one of the most important occupational disease in worldwide. NIHL has been found to be potentiated by simultaneous Carbon monoxide (CO) exposure. Exposure to noise plus CO is common in occupational and environmental settings. Free radicals have been implicated in cochlear damage resulting from exposure to noise and due to CO hypoxia This s...

BACKGROUND Noise, or undesirable sound, is one of the most common environmental stressors, and it can cause various health effects. Beyond the auditory consequences of occupational noise exposure, extra-auditory effects such as psychological problems have also been found. The aim of the current study is to elucidate the association between occupational noise annoyance and psychological symptoms...

This paper comprises a review of the evidence for the possibility that exposure to noise may damage the vestibular receptors in the internal ear as well as those in the cochlea. The review covers lay and medical publications, observations on patients, experimental studies, and compensation claims. It concludes that the verdict must be "not proven"-that is, although such damage is possible, the ...
