Hearing ability according to screening at conscription; comparison with earlier reports and with previous screening results for individuals without known ear disease.

Objective: (1) To study if young, Swedish men have poorer or better hearing according to screening at conscription in 1988 compared to 1969-1977. (2) To study how the results of screening and audiometry vary across the teenage years for a group of boys without middle ear disease.

Method: A birth cohort has earlier been well documented regarding results in four general screenings with follow-up and examinations and treatment for middle ear disease at the ENT departments in the area.

Hearing loss as a sequel of secretory and acute otitis media as reflected by audiometric screening of Swedish conscripts.

Objective: Many authors have shown a small effect on hearing from middle ear disease even a long time after active disease has subsided. We wanted to see to what extent those who have had otitis media in childhood in our district have normal hearing at the age of 18 years. The aim of the present study is to find out if a history of secretory otitis media (SOM) up to 14 years of age or acute otitis media (AOM) up to 4 years of age affects hearing at conscription in an age cohort of Swedish boys.

Demonstration of Chlamydia pneumoniae in the adenoid from children with and without secretory otitis media using immunohistochemistry and PCR.

Chlamydia pneumoniae has been found in patients with middle ear inflammation. The adenoid, which has a central role in the development of secretory otitis media (SOM), may act as a reservoir for bacteria causing ear infection. Adenoid tissue was examined for the presence of C.

Otitis media and academic achievements.

Objective: This is a study of whether there are any long-term differences in academic achievements between children with and without observed or treated middle ear disease in a population with a stable long-standing treatment policy.

Methods: A birth cohort of 2156 children was previously studied through a questionnaire to the parents at 4 years of age, follow-up after audiometric screening at 4, 7, 11 and 14 years of age, and study of records from all Ear, Nose and Throats departments in the area; 2095 of these still lived in the area and received academic grades on leaving the ninth year of the state school system. We have compared these grades, and the choice of high school course for children with different experiences of otitis media.
