Abstract
We prospectively followed 246 children with tympanostomy tubes and observed acute otorrhea through a functioning tube at least once in 50% of subjects. Pathogens typical of acute otitis media ( Streptococcus pneumoniae, Hemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes) were found in 42% of all episodes; Pseudomonas aeruginosa or Staphylococcus aureus was found in 44% of all episodes. Pathogens of acute otitis media were found in 50.0% of subjects under 6 years old versus 4.4% of subjects 6 years or over at the first episode (p < .001). Pseudomonas aeruginosa was found more often in children 6 years or older (43.5% versus 20.5% at the first episode, p = .052). Pathogens typical of acute otitis media were less prevalent in the summer months (14.7% versus 52.2% for the first episode, p = .001), while P aeruginosa was more prevalent in summer (44.1% versus 16.4% for the first episode, p = .006). This suggests that while many younger children with acute otorrhea may respond to treatment with oral antimicrobials alone, outpatient therapy of older children may involve use of topical antipseudomonal agents that may be complicated by the question of the safety of such medications.
