The authors studied the epidemiology of pharyngitis in children and evaluated the contribution of a rapid streptococcal test.
This prospective study was conducted from June 2007 to May 2008 in a primary health care institution (Policlinique de la Caisse Nationale de Sécurité Sociale) in Tunisia. Clinical findings were recorded; throat swabs were performed, and a rapid streptococcal test was made.
Five hundred and four children were included in this study. The mean age was 5 years and 8 months. Culture was positive for group A streptococcus in 166 cases (32.9 %). Group A streptococcus was more frequently isolated in children aged 5 to 8 years. There was no difference in clinical features between groups of streptococcal and non-streptococcal pharyngitis. The sensitivity and specificity of the rapid test were respectively 93.2 and 95.3 %.
Pharyngitis was of bacterial origin in one third of cases; among these, group A streptococcus was the most frequent bacterium. The rapid test is a quick and reliable tool for the diagnosis of pharyngitis and hence an appropriate treatment.
作者研究了儿童咽炎的流行病学，并评估了快速链球菌检测的作用。
这项前瞻性研究于2007年6月至2008年5月在突尼斯的一家初级卫生保健机构（国家社会保障基金综合诊所）进行。记录临床症状；采集咽拭子，并进行快速链球菌检测。
本研究纳入了504名儿童。平均年龄为5岁8个月。166例（32.9%）A组链球菌培养呈阳性。A组链球菌在5至8岁儿童中分离更为频繁。链球菌性咽炎组和非链球菌性咽炎组的临床特征无差异。快速检测的敏感性和特异性分别为93.2%和95.3%。
三分之一的咽炎病例为细菌感染；其中，A组链球菌是最常见的细菌。快速检测是诊断咽炎从而进行适当治疗的一种快速且可靠的工具。
