Describe essential features, including methods and duration of administration.
Be precise and concise. Use sensitivity, specificity, and positive predictive and negative predictive values, when appropriate. Give main results of study.
All major conclusions supported by data should be given. Provide clinical application; be conservative and do not overgeneralize. Note if additional study is recommended.
To determine whether beta-hemolytic streptococci (BHS) from groups other than A are an important cause of sporadic pharyngitis in children
Cross-sectional, case-referent survey
General pediatric clinic at a military base in Ohio
150 children with symptomatic pharyngitis and 150 controls matched for age and time of presentation over a 20-month study period
Anaerobic culture technique was used to improve isolation of BHS. Group A BHS was detected significantly more often among the ill children than among the controls (39% vs. 16%, p<0.01). In contrast, non-group A BHS were isolated in similar frequency from the ill and control children (17% vs. 21%). Non-group A BHS from groups B, C, F, and G were each isolated in similar frequency among the ill and control children. The isolation rate of non-group A organisms increased with age among both patients and controls.
Non-group A BHS appeared not to be an important cause of sporadic pharyngitis in this pediatric population.
