RESUMO
This study estimated the prevalence of hearing disorders and associated risk factors in a 10% sample of all secondary-school students in Ismailia city, Egypt. All participants were given a questionnaire and Weber and Rinne tests for hearing disabilities. Among 2633 students, the prevalence of hearing loss was 22.2%, mostly sensorineural hearing loss. More students at technical schools had mixed sensorineural and conductive hearing loss [46.2%] than students at general [28.6%] or commercial [25.3%] schools. Multivariate logistic regression analysis identified the number of attacks of otitis media, history of ear disease treatment, history of admission to fever hospital and history of ear surgery as independent risk factors for sensorineural hearing loss

This study aimed to describe the trend and to identify possible risk factors for brucellosis in Alexandria in northern Egypt. We enrolled 72 confirmed cases of brucellosis and 144 age-matched controls in this study. Participants were interviewed at home using a structured questionnaire. Working with animals, breeding goats and eating ice cream bought from street vendors were significantly associated [P < 0.05] with brucellosis by univariate and multivariate analysis. Contact with infected animals and their products was the most important method of transmission
