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...
background acoustic trauma is an injury to the hearing mechanisms in the inner ear due to excessive noise. this injury is the most prevalent cause of sensorineural hearing loss in humans, especially from occupational exposure. previous studies have shown the essential role of free radical formation in the inner ear hearing loss caused by acoustic trauma. objectives this study was performed to d...
Current studies are inconclusive regarding specific patterns of gender differences in age-associated hearing loss. This paper presents results from the largest and longest longitudinal study reported to date of changes in pure-tone hearing thresholds in men and women screened for otological disorders and noise-induced hearing loss. Since 1965, the Baltimore Longitudinal Study of Aging has colle...
Noise-induced hearing loss, which is one of the 10 leading occupational diseases, is a debilitating and irreversible disease. During the recent 15-years period (1997-2012), several studies have investigated the association between noise, hearing damage and other side effects of noise in Iran. The aim of this study was to review systematically the relevant literature related to noise-induced hea...
consanguineous marriage is strongly favored in many large human populations. in the most parts of south asia, consanguineous marriage account for 20% to over 50% of the general population. the effect of consanguinity on hereditary deafness has been well studied and documented. many authors have suggested that approximately one half of sensory neural hearing loss in children can be attributed ...
Background : Normal hearing is essential for development of appropriate academic and psychosocial skills in children. Many causes of hearing loss are preventable and curable. The aim of this study was to investigate the prevalence of types and probable causes of hearing loss in 15-5 years old hearing impaired children in Isfahan. Methods: In a cross-sectional descriptive study conducted dur...
induced hearing loss. Noise induced hearing loss may not be noticeable for years, but with time normal sounds may become distorted and it may be difficult for the person to understand speech. Akin to many overuse injuries, hearing loss is cumulative, but unlike overuse injuries hearing loss is permanent.1 It depends on the sound intensity, exposure, types of earphone used, type of music listene...
background and aims: this is a pilot study investigated the prevalence of hearing impairment and the impact of the known risk factors for hearing loss on infants at risk born in kuwait. methods: two hundred infants with risk of hearing impairment who met the joint committee on infants hearing (1990) criteria were screened. all newborns were included in this study if they had hospital stay for m...
original article extended exposure to noise can cause permanent hearing damage. this study aimed to determine the incidence time of hearing loss and its effective factors in workers exposed to noise. this retrospective cohort study, was conducted on a total of 273 workers in various sectors of kerman copper by-industries co. their hearing status and the incidence of hearing loss (hearing thre...
