Background: Hearing loss induced by noise is one of the well-known and main health problems of occupational exposures. As a result, the current study sought to examine the association between age, working experience, and smoking status and hearing loss among sugar factory workers. Materials and Methods: This cross-sectional study was conducted in 2016 among 270 workers of a sugar factory in Fa...

The main objective of this study is to provide an overview of the basic mechanisms of blast induced hearing loss and review pharmacological treatments or interventions that can reduce or inhibit blast induced hearing loss. The mechanisms of blast induced hearing loss have been studied in experimental animal models mimicking features of damage or injury seen in human. Blast induced hearing loss ...

A review of the problems of noise induced hearing loss in children, especially related to recreational music and the use of personal entertainment devices. The patho-physiology of noise induced hearing loss, and associated problems (e.g. tinnitus) are discussed. The evidence for an increase in noise induced hearing loss in children and young people is reviewed. Some practical advice (for clinic...

hearing loss (hl) is the most common sensory defect. various genetic as well as environmental factors have been shown to contribute in it. more than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (arnshl). here, we report a 6-year old female patient with bilateral pre-lingual hl in whom a mutation has been identified in triobp gene (c.6362c>t, s2121l). in s...

Exposure to chemicals in the workplace can lead to occupational chemical-induced hearing loss, as many chemicals have been internationally recognised as hazardous to hearing. A number of studies have demonstrated that, similar to noise, some chemicals not only affect the sensory organ of the auditory system (the cochlea) but also lead to adverse effects in central auditory structures. Morata an...

the paper is based on a study conducted in three different industries on 84.4 on their employees to determine the effect of over all noise intensity, length of employment and rest periods among them. it was found that the mentioned factors have direct effect on the induced hearing loss among the exposed workers. high noise level and long period of employment adversely affect the hearing ability...

Background. Sudden sensorineural hearing loss (SSHL) caused by opiate abuse or overuse has been well documented in the medical literature. Most documented case reports have involved either heroin or hydrocodone/acetaminophen. Recently, case reposts of methadone induced SSHL have been published. Case Report. We present the case of a 31-year-old man who developed SSHL after a methadone overdose i...
