Reactive oxygen species (ROS) production is involved in several apoptotic and necrotic cell death pathways in auditory tissues. These pathways are the major causes of most types of sensorineural hearing loss, including age-related hearing loss, hereditary hearing loss, ototoxic drug-induced hearing loss, and noise-induced hearing loss. ROS production can be triggered by dysfunctional mitochondr...

Introduction: The purpose of this study was to develop a statistical model for prediction of radiation induced sensorineural hearing loss (SNHL) induced by radiotherapy in patients with brain tumors.   Materials and Methods: CT scan of 18 patients (10 males and 8 females) with brain tumor who were referred to Radiation Center of Milad Hospital in Isfahan in 2...

OBJECTIVES Guidelines published in 2000 by the authors are widely used by medical and legal professionals in the UK for diagnosis of noise-induced hearing loss in a medicolegal context. However, they cannot be used for quantification of the noise-induced hearing loss, which is required in most cases. This requirement is addressed. DESIGN A method is developed here to quantify noise-induced he...

INTRODUCTION The 2016 National Academies of Sciences report "Hearing Health Care for Adults: Priorities for Improving Access and Affordability" included a call to action for government agencies to strengthen efforts to collect, analyze, and disseminate population-based data on hearing loss in adults. METHODS CDC analyzed the most recent available data collected both by questionnaire and audio...

abstract background: previous studies have indicated an unspecific correlation between noise exposure and blood pressure disturbances. blood pressure disturbances could be caused by the environmental hazards such as noise exposure. the aim of this study is to analyze whether there is a relationship between noise exposure and hypertension. methods: atotal sample of 218 workers working in a small...

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...

INTRODUCTION Tinnitus is one of the symptoms that affects individuals suffering from noise induced hearing loss. This condition can be disabling, leading the affected individual to turn away from work. OBJECTIVE This literature review aims to analyze the possible association between gender and tinnitus pitch and loudness, the degree of hearing loss and the frequencies affected in subjects wit...

Hearing plays a vital role in the performance of a soldier and is important for speech processing. Noise-induced hearing loss is a significant impairment in the military and can affect combat performance. Military personnel are constantly exposed to high levels of noise and it is not surprising that noise induced hearing loss and tinnitus remain the second most prevalent service-connected disab...

hearing loss and meningitis were correlate in some aspects. hearing loss is the situation that can be shown in cochlear or retrocochlear defects. cochlear hearing loss is caused by inner or outer hair cell damage (however cochlear hearing loss has another causes, such as defect of arterial spiral ganglion, basilar and tectorial membrane) and retrocochlear hearing loss has neural origin and meni...
