All children were without any subjective ear symptoms. Two and eight tenths percent of the children were found to have SOM. The relation between SOM and the appearance of allergy, the occurrence of earlier otitis media, the occurrence of repeated upper respiratory tract infections and the treatment of earlier middle ear infections are discussed.<\/jats:p>","DOI":"10.1177\/00034894800890s305","type":"journal-article","created":{"date-parts":[[2017,1,6]],"date-time":"2017-01-06T07:43:08Z","timestamp":1483688588000},"page":"7-10","source":"Crossref","is-referenced-by-count":26,"title":["Prevalence of Secretory Otitis Media in Seven to Eight Year Old School Children"],"prefix":"10.1177","volume":"89","author":[{"given":"Erkki","family":"Virolainen","sequence":"first","affiliation":[{"name":"Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pekka","family":"Tuohimaa","sequence":"additional","affiliation":[{"name":"Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heikki","family":"Puhakka","sequence":"additional","affiliation":[{"name":"Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olli","family":"Ruuskanen","sequence":"additional","affiliation":[{"name":"Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eero","family":"Aantaa","sequence":"additional","affiliation":[{"name":"Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Otto H.","family":"Meurman","sequence":"additional","affiliation":[{"name":"Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1980,5,1]]},"reference":[{"key":"bibr1-00034894800890S305","first-page":"497","volume":"52","author":"Greydanus DE","year":"1977","journal-title":"Mayo Clin Proc"},{"key":"bibr2-00034894800890S305","first-page":"1297","volume":"1","year":"1978","journal-title":"Lancet"},{"key":"bibr3-00034894800890S305","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1974.00780030332002"},{"key":"bibr4-00034894800890S305","doi-asserted-by":"crossref","first-page":"488","DOI":"10.4049\/jimmunol.112.2.488","volume":"112","author":"Ogra PL","year":"1974","journal-title":"J Immunol"},{"key":"bibr5-00034894800890S305","doi-asserted-by":"publisher","DOI":"10.3109\/00016487609120859"},{"key":"bibr6-00034894800890S305","doi-asserted-by":"publisher","DOI":"10.1177\/00034894760850S220"},{"key":"bibr7-00034894800890S305","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.1967.02090270140022"},{"key":"bibr8-00034894800890S305","unstructured":"Kokko E.
