All patients received oseltamivir. Fifty\u2010four patients (0.55%) who presented with bacterial upper respiratory infection within 2\u00a0months after the diagnosis of influenza were selected. The median time to presentation with bacterial respiratory infection was 12\u00a0days. Median age was 12 years, and 51.8% were male. The most common bacterial upper respiratory infections were acute rhinosinusitis (46.4%; median age, 17 years), acute otitis media (33.9%; median age, 5 years), and pharyngotonsillitis (14.3%; median age, 17 years). Four patients were hospitalized: 3 with streptococcal tonsillitis with prolonged fever and 1 with acute otitis media who later developed pansinusitis and otomastoiditis. There were no deaths in this group of patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>There were few bacterial upper respiratory infections associated with influenza A (H1N1) (0.55%). The most common infections were acute otitis media in young children and acute rhinosinusitis and pharyngotonsillitis in young adults. These complications were more often seen during the 2\u00a0months following the influenza infection than at the time of diagnosis with influenza. Outcome was favorable for all patients.<\/jats:p><\/jats:sec>","DOI":"10.1177\/0194599811425765","type":"journal-article","created":{"date-parts":[[2011,10,14]],"date-time":"2011-10-14T00:02:36Z","timestamp":1318550556000},"page":"478-482","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Otolaryngological Complications in Patients Infected with the Influenza A (H1N1) Virus"],"prefix":"10.1002","volume":"146","author":[{"given":"Catalina","family":"Gutierrez","sequence":"first","affiliation":[{"name":"Clinica Las Condes University of Chile Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gonzalo Andres","family":"Nazar","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Clinica Las Condes Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Pablo","family":"Torres","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Division of Pediatric Infectious Diseases Clinica Las Condes Faculty of Medicine University of Chile Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,10,13]]},"reference":[{"key":"e_1_2_8_2_2","unstructured":"Influenza (seasonal).
