    ABSTRACT: : Prospective studies using bacterial eradication as the endpoint have demonstrated that once-daily amoxicillin is as effective as twice-daily amoxicillin for treatment of Group A β-hemolytic streptococcal (GABHS) pharyngitis. : The aim of this study was to determine, in a retrospective study, whether treatment of symptomatic GABHS pharyngitis with once-daily amoxicillin was as effective in preventing clinical recurrences as twice-daily amoxicillin or cephalexin in pediatric office practice, using patient-initiated return visits for streptococcal pharyngitis as a pragmatic, clinical endpoint. : The charts of consecutive patients 2 years of age and older with laboratory-proven GABHS pharyngitis for a period of 2 years were reviewed to identify index cases of streptococcal pharyngitis and subsequent episodes. Age, weight, antibiotic treatment and time from index to subsequent episodes of GABHS pharyngitis were recorded. : In 1402 index episodes, patients received amoxicillin once-daily (231), amoxicillin twice-daily (846) or cephalexin (325). The risk of symptomatic streptococcal pharyngitis in the 4 months after treatment of the index episode was not statistically different among the 3 treatment groups: amoxicillin once-daily (15.1%), amoxicillin twice-daily (19.6%) and cephalexin (19.1%). There was a trend toward reduction in the risk of recurrences in the 6 weeks after completion of antibiotics in the cephalexin (9%) group compared with the combined amoxicillin (13%) groups. : Amoxicillin once-daily or twice-daily was equally effective in terms of frequency of recurrence of symptomatic GABHS pharyngitis.

    ABSTRACT: To determine how frequently acute otitis media (AOM) occurs, we enrolled children between 6 months and 3 years of age who returned several weeks before and 6 to 10 times during a cold for tympanometry and photography of the tympanic membrane. American Academy of Pediatrics (AAP) criteria were used to diagnose AOM. Children visited their physicians at their discretion. AOM occurred in 17 (55%) of 31 colds; in 12 (100%) colds with pre-existing middle ear effusion (MEE); and in 5 (26%) of 19 colds with no pre-existing MEE (P < 0.0001). Four patients received antibiotics from their physicians. Of 17 children with AOM, 12 did not seek care. AOM is common during colds, particularly with pre-existing MEE.
