introduction: sudden sensorineural hearing loss (ssnhl) is a frightening and frustrating symptom for the patient as well as the physician. prognosis is affected by multiple factors including duration of hearing loss, presence of associated vertigo and tinnitus, and co-morbidities such as hypertension and diabetes. materials and methods: forty subjects presenting to our department with feature...
Background & Aim: Consanguineous marriage is strongly favored in many large human populations. In most parts of South Asia, consanguineous marriage accounts for 20-50% of the total present generation. 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 ...
Background and aims: Exposure to excessive noise is a serious threat to the health of industrial workers' hearing. This is a study of hearing problems among workers in the sugar cane industry in Khoozestan Province. Methods: In this descriptive-analytical study, the hearing status of 265 employees, including workers in different sectors and administrative employees, was checked in terms o...
Introduction: The occupational noise induced hearing loss is one of the wide spread problems and a long term complication of working in noisy environments. At the present, large groups of workers who are working in noisy environments are exposed to hearing loss. So, this study is aimed to determine the prevalence of hearing loss (more than, 25 dB) of the workers in coal mines and leaching fac...

Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this paper, a new fire ignition model is proposed and applied to a conventional semi-probabilistic model for estimating various losses due to damage of an urban gas network in an eart...
