Abstract

Acute otitis media (AOM) is a common disease in childhood. If predictors of outcome in AOM are known, it will be possible to individualize and select the appropriate therapy. We have employed the scoring system using severity of symptoms and severity of tympanic membrane changes and reported the usefulness in inferring the outcome of AOM. The aim of this study was to compare clinical significance of the scoring systems between that of Wakayama Medical University and that proposed by Japan AOM Guideline Committee. In this study, tow outcomes were assessed, i.e, persistence of symptoms at day 5 and persistence of tympanic membrane change at day 28. In both scoring systems, persistence of symptoms at day 5 was associated with younger age, higher symptom score on day 1 and colonization with S. pneumoniae.<BR>By using Wakayama Scoring System, persistence of tympanic membrane changes at day 28 was significantly associated with younger age, higher tympanic membrane score at day 1, nasopharyngeal colonization with S. pneumoniae, especially PRSP. On the other hand, the scoring system proposed by the committee showed that the significant persistence of tympanic membrane changes was associated with younger age and nasopharyngeal colonization of S. pneumoniae. The scoring system of the committee could not find any significance in tympanic membrane score at day 1 on the outcome of AOM. This study strongly suggested that decreased landmarks/cloudiness of drums is essential factor for the scoring system of AOM.
