In a modern hospital built recently in Sri Lanka the staff members on night shifts and some patients in the open wards were known to be affected by an acute vesicating dermatitis. The study was carried out to identify the cause of the dermatitis and recommend preventive measures.
Members of the hospital staff and patients who developed an acute vesicating dermatitis over a period of 2 years were studied using a questionnaire. The clinical features, relationship to night shifts and the month of occurrence were noted. Insects were caught at night on several occasions and identified. Lesions were reproduced in volunteers.
Out of a total of 124 patients studied, 108 were members of the hospital staff and it was noted that they had all been on night shifts within 2 days prior to the onset of the lesions. The insect caught belongs to class Coleoptera, family Staphylinidae, genus Paederus, and species fuscipes. The incidence was seasonal with clustering of cases seen to occur twice a year.
This is an outbreak of dermatitis due to Paederus fuscipes. Awareness of the condition and its clinical features will prevent misdiagnosis and the simple preventive measures suggested are based on the behavioral pattern of this nocturnal beetle.
在斯里兰卡最近新建的一家现代化医院里，已知夜班工作人员和开放式病房中的一些患者受到急性水疱性皮炎的影响。开展该研究以确定皮炎的病因并推荐预防措施。
使用问卷对在两年时间里出现急性水疱性皮炎的医院工作人员和患者进行研究。记录临床特征、与夜班的关系以及发病月份。多次在夜间捕捉昆虫并进行鉴定。在志愿者身上重现病变情况。
在总共研究的124名患者中，108名是医院工作人员，并且注意到他们在病变发作前2天内都上过夜班。捕获的昆虫属于鞘翅目、隐翅虫科、隐翅虫属、梭毒隐翅虫种。发病率呈季节性，病例聚集现象一年出现两次。
这是一次由梭毒隐翅虫引起的皮炎暴发。了解这种疾病及其临床特征将防止误诊，所建议的简单预防措施基于这种夜行甲虫的行为模式。
