title: Upper respiratory tract infections - otitis media, sinusitis and pharyngitis.
abstract: Management of the patient with otitis media, sinusitis or pharyngotonsillitis is based on information about the host, the organism and the antimicrobial agent. Otitis media (OM) is a common infection in children but selected children have recurrent and chronic OM. The predominant organisms responsible for OM are Streptococcus pneumonia, Haemophilus influenzae and Moraxella catarrhalis. Changes in the antimicrobial susceptibility govern the choice of antimicrobial agents. Surgical treatment should be considered if the child has persistent hearing loss in both ears. Sinusitis shares with OM similar pathogenesis, microbiology and choices of antimicrobial therapy. Endoscopic surgery is the treatment of choice for chronic sinusitis. Pharyngitis may be either viral or bacterial in origin. Penicillin remains the treatment of choice for bacterial pharyngotonsillitis. In patients with recurrent infection, the emergence of B-lactamase producing strains has to be considered and erythromycin or oral cephalosporins might be indicated.
