 note = {論文(Article), Background: The Centor criteria and a rapid antigen detection test（RADT）are commonly used to diagnose streptococcal pharyngitis. We evaluated the relationships between specific erythema of the throat, Centor criteria, and positive RADT results to clarify the usefulness of direct observation with a thin USB camera.
Methods: We observed the pharynx of 161 patients aged 0–15 years using a thin USB camera. We also evaluated the Centor criteria and presence of specific erythema. We performed an RADT as pathological proof. Fisher’s exact tests were conducted to assess the differences in the findings between RADT-positive and RADT-negative patients.
Results: Of the 87 patients who underwent RADT, specific erythema was present in 23（26.4%）, and 8（9.2%） met three Centor criteria and had specific erythema. The RADT results were positive for 17 of the 23 with specific erythema（73.9%; p < 0.001）and for 7 of the 8 who met three Centor criteria and had specific erythema（87.5%; p < 0.001）.
Conclusion: A high proportion of the patients with specific erythema of the throat had positive RADT results for streptococcal pharyngitis. A thin USB camera can provide exact clinical findings for both evaluators and patients with a low-cost and simple technique.},
