Subacute sinusitis: are antimicrobials necessary?
BACKGROUND: The need for antimicrobials in the treatment of subacute sinusitis was evaluated in 96 afebrile children who were prescribed antimicrobial (amoxicillin, amoxicillin clavulanate potassium, or trimethoprim-sulfamethoxazole) or no antimicrobial medication in addition to a decongestant and saline nasal spray for 3 weeks. METHODS: Response was determined by complete clearing of the initial radiologic abnormalities or in the case of mucosal thickening, by a significant decrease in thickness to < 6 mm within the maxillary sinuses associated with improvement of the clinical signs and symptoms of sinusitis. If there was evidence of partial clearing by radiograph, the same therapy was continued for another 3 weeks. Nonresponders demonstrated no change or worsening of clinical and radiologic findings. RESULTS: Sixty-seven of the 96 subjects (70%) responded: 58 (87%) in 3 weeks and 9 (13%) in 6 weeks. Fifty-five of the responders were in the antimicrobial treatment group, and 12 were prescribed no antimicrobial medication. Twenty-nine of the 96 subjects (30%) did not respond to treatment; 22 received an antimicrobial and seven received no antimicrobial medication. CONCLUSIONS: The number of responders and nonresponders was similar in the antimicrobial- and nonantimicrobial-treated groups (p = NS), and no single antimicrobial medication demonstrated greater treatment effectiveness.

Expired breath hydrogen peroxide is a marker of acute airway inflammation in pediatric patients with asthma.
Airway inflammation is important in the development and progression of many pulmonary disorders, including asthma. We hypothesized that the hydrogen peroxide (H2O2) concentration in expired breath may be a marker of airway inflammation. Expired breath condensate was collected by cooling and the H2O2 concentration was measured fluorimetrically. Thirty-five samples were collected from 22 pediatric patients with asthma who were 7 to 18 yr of age and from 11 healthy, nonasthmatic controls. Asthmatic subjects were determined to be well or sick (acute disease of the upper or lower respiratory tract) by clinical examination. Pulmonary function tests were determined to be abnormal if there was a > 15% reduction in FEV1 or > 20% reduction in FEF25-75 compared with baseline values. Expired breath H2O2 was elevated in asthmatic subjects compared with controls (0.81 +/- 0.70 versus 0.25 +/- 0.27 mumol/L). The difference was primarily due to elevation of H2O2 in sick asthmatic subjects, whose expired breath H2O2 level of 1.5 +/- 0.5 (n = 10) was different from that of well asthmatics (0.54 +/- 0.56, n = 25). There was a high correlation between expired breath H2O2 and clinical status. Elevation of expired H2O2 occurred with either acute upper or lower respiratory tract disease. There was no statistically significant correlation between expired breath H2O2 level and pulmonary function test results. We conclude that elevation of H2O2 in the expired breath condensate is a simple, noninvasive method that can be used as a biochemical marker of airway inflammation.
