儿童皮肤软组织化脓性感染750例临床调查

Clinical investigation of 750 outpatients with purulent skin and soft tissue infections in children

【目的】了解儿童皮肤软组织化脓性感染（skin and soft tissue infections，SSTIs）的临床特点和金黄色葡萄球菌（staphylococcus aureus，SA）的分离情况。【方法】对北京儿童医院2008年9月～2009年3月的750例SSTIs患儿进行现场调查。【结果】儿童SSTIs中男性明显多于女性，比例为2．36：1，好发年龄为0～3岁；疾病类型以脓肿最多见，其中最常见的是颈部脓肿，其次为肛门周围脓肿。新生儿最常见的是脐炎，脚趾甲沟炎多见于学龄期儿童，而手指甲沟炎多见于婴幼儿。儿童SSTIs感染的好发部位为四肢、颈部、肛门周围、脐部；在750例患儿的脓液标本中分离出SA247株，分离率为32．9％。【结论】SSTIs在性别、年龄、疾病种类、感染部位等方面具有明显的临床特点；SA是引起儿童SSTIs的重要病原体。

[Objective] To research the clinical characteristic and the separation of staphylococcus aureus（SA）of purulent skin and soft tissue infections （SSTIs）in children. [Methods] Total 750 outpatients with SSTIs in Beijing Children＇s Hospital during 2008.9～2009.3 were researched on-the-spot. [Results] In total outpatients quantity of SSTIs in children, boys were more than girls obviously. The proportion of boys and girls was 2.36 ： 1, the predilection age of onset was 0～3 year old. The most frequent type was abscess,and the number of abscess of neck was the first most,and perianal abscess was the second;Omphalitis in newborn infant was most to see frequently; the phlogosis of nail groove in toenail was frequent at school age, but the paronychia of finger is frequent in young children. The predilection sites were limbs,neck,eircum-anus and pars umbilical region 247 strains of SA had been separated from 750 outpatients,the isolating rate was 32.9%. [Conclusion] There are many clinical characteristics of SSTIs in children in sex,age,type of disease and predilection site; SA is the important pathogen of SSTIs in children with community acquired.
