MedPage Today, Nov. 7, 2006 TURKU, Finland, Nov. 7 -- Most children with acute otitis media have infections caused by both bacteria and viruses, suggesting that antibiotics may not be enough to control the infections, researchers here have found.  "For severe acute otitis media cases for which antibiotic is indicated, viral coinfection could lead to clinical failure even when appropriate antibiotic has sterilized the middle ear fluid," wrote Tansee Chonmaitree, M.D., of the University of Texas Medical Branch in Galveston, in an accompanying editorial.
