Prevalence and risk factors for hearing disorders in secondary school students in Ismailia, Egypt

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

Actinomycosis of the adenoids: a histopathological study

One hundred and forty adenoidectomy specimens were examined for the presence of actinomycosis colonies. Hematoxylin and Eosin, P.A.S. and gram stain were used. Complete clinical evaluation was performed for all patients pre-operatively. Colonies could be demonstrated in 9.2 percent of the specimens. More than 30 percent of them showed tissue invasion with surrounding chronic inflammatory reaction. Halitosis was a common complaint in about 40 percent of patients with positive specimens. Actinomycosis is most probably a contributing factor for this symptom
