BACKGROUND Noise-induced hearing loss (NIHL) is a complex disease caused by environmental and genetic risk factors. This study explored the relationship between the genetic variations in the CASP gene and the risk of developing NIHL among Chinese workers exposed to occupational noise. METHODS A case-control study of 272 NIHL workers and 272 normal-hearing workers matched for age, sex and year...

One of the most important occupational diseases encountered in mining is noise induced hearing loss (NIHL). In this study, analyses were carried out to examine NIHL open pit lignite mine Turkey. The was evaluated accordance with miners’ age, experience, occupation, exposure value (Lex), and maximum level (Lpeak). Noise levels exposed employees measured dosimeters a test applied by special cente...

BACKGROUND Both environmental and genetic factors are attributable to the incidence of noise-induced hearing loss (NIHL). The purpose of this study was to examine the associations between genetic variations in the EYA4, GRHL2 and DFNA5 genes and the risk to noise-induced hearing loss (NIHL) in a Chinese population. METHODS A case-control study was conducted with 476 NIHL workers and 475 norma...

BACKGROUND Workplace safety regulations seek to mitigate noise-induced hearing loss (NIHL), conventionally associated with the shipbuilding industry. Despite this, are workers still predisposed to NIHL? AIMS To study the prevalence of NIHL among noise-exposed subjects in the shipbuilding industry in Goa and to compare it with that among the non-exposed population working in the same industry ...

Objectives Occupational noise-induced hearing loss (NIHL) due to industrial, military, and other job -related noise exposure can cause harmful health issues occupied workers, but may also be potentially preventable. Vitamins/antioxidant have been studied as therapeutic strategies prevent and/or delay the risks of human diseases well NIHL .So, this study was conducted systematically review prote...

Noise-induced hearing loss (NIHL) is the second-most frequent form of sensorineural hearing loss. When exposed to the same noise, some workers develop NIHL while others do not, suggesting that NIHL may be associated with genetic factors. To explore the relationship between single nucleotide polymorphisms (SNPs) in heat shock protein 70 (HSP70) genes (HSPA1A, HSPA1B and HSPA1L) and susceptibilit...

BACKGROUND Noise-induced hearing loss (NIHL) is a major preventable occupational health problem with 250 million people worldwide known to have disabling impairment of moderate to greater severity. The aims of the study are to estimate the prevalence of NIHL in the police force; and study its association with age, sex, duration of service (years), smoking and alcohol habits, use of hearing prot...

Noise-induced hearing loss (NIHL) is one of the most common sensorineural hearing deficits. Recent studies have demonstrated that the pathogenesis of NIHL is closely related to ischemia-reperfusion injury of cochlea, which is caused by blood flow decrease and free radical production due to excessive noise. This suggests that protecting the cochlea from oxidative stress is an effective therapeut...

INTRODUCTION Currently, there is limited information about the relationship between manganese superoxide dismutase (sod2) c47t polymorphism and susceptibility to noise-induced hearing loss (NIHL). OBJECTIVE The aim of this meta-analysis was to clarify the association between SOD2 C47T polymorphism and NIHL. METHODS A search in PubMed and Web of Science was performed to collect data. All ful...

Although there is no specific treatment for modality of occupational noise-induced hearing loss (NIHL), the best way to manage this problem is the prevention. The fundamental prevention of NIHL is to find the persons who are more susceptible to the noise and to avoid work in the noisy environment prior to or during employment. The purpose of this study is to investigate the actual status of NIH...
