Overview
Brief Summary
The investigators objective is to compare short course (5 days) to long course (14 days)antibiotics for the treatment of acute bacterial sinusitis in children. The investigators hypothesize that short course therapy will lead to more frequent relapses of sinusitis and will not reduce resistant organisms.
Detailed Description
This was a prospective, randomized, double-blind study comparing short course (5 days) to long course (14 days) antimicrobial therapy for children between 1 and 10 years of age with acute bacterial sinusitis. The major outcome measure is the proportion of children with a clinical relapse on day 10 in the short course therapy group compared to day 20 in the long course therapy group. In addition, the proportion of respiratory flora that are resistant to antibiotics on day 30 will be compared to baseline in each group.

Eligibility Criteria
Inclusion Criteria
- •children with nasal discharge (of any quality) or daytime cough (which may be worse at night) or both persisting for 10 days or more without evidence of improvement.
- •families need to be English speaking
Exclusion Criteria

Outcomes
Primary Outcomes
Proportion of Children With Clinical Relapse on Day 10 (Short Course) vs Day 20 (Long Course)
Time Frame: at 10 days and at 20 days
Results are based on a daily 6-item symptom survey (day 1 to 14); a daily 3-item survey (day 15 to 30). If a particular symptom is present initially, a score of 2 is given; if it is absent the score is 0. A maximum entry score is 20 (persistent symptoms). If a particular symptom becomes more severe, less severe, or stays the same during treatment, +1, -1, or 0 respectively, will be added to the original score for each symptom. At 10 (and 20 days, respectively), children will be classified as cured, improved or failed based on survey results. Children will be considered cured if they reach a score of \< 2. Children will be classified as improved if their score at 10 days (20 days, respectively) is at least 2 points less than their score at 5 days (15 days, respectively). Children will be considered to have failed therapy if their score worsens by + 3 between day 5 (day 15) and day 10 (day 20) or if their score at day 10 (day 20) does not meet criteria for improvement.
