The skin has become a target organ for concerns related to work with video display units (VDU). The aim of this investigation was to describe the clinical picture, to investigate whether skin problems are more common in VDU-exposed persons than in non-exposed controls, whether there are differences in objective and/or subjective symptoms and signs, and whether there is a "specific" dermatosis associated with VDU work. A self-reported questionnaire was mailed to 3,877 individuals. One out of five questions concerned the presence of skin problems. Of this group, 809 underwent a clinical dermatological evaluation in addition to filling out a structured questionnaire. Self-reported skin symptoms increased with increasing exposure to the VDU. The clinical diagnosis, based on objective signs and anamnestic data showed a somewhat attenuated association with exposure. The status diagnosis, based solely on objective signs, failed to show any association to VDU exposure. Unilateral skin rashes occurred at the same frequency in the exposed and the non-exposed groups. It is concluded that there is nothing in this investigation, or in any other investigation, that would speak against the notion that VDU-related skin problems and the allergy to electricity is just another facet of the "20th century syndrome". It is possible that individuals suffering from this condition, are conditioned to respond to certain stimuli by neurogenic release of mediators.
皮肤已成为与视频显示终端（VDU）工作相关问题的靶器官。本调查的目的是描述临床表现，研究VDU暴露人群的皮肤问题是否比未暴露的对照组更常见，客观和/或主观症状及体征是否存在差异，以及是否存在与VDU工作相关的“特异性”皮肤病。一份自我报告问卷被邮寄给3877人。五个问题中有一个涉及皮肤问题。在这组人中，809人除填写结构化问卷外，还接受了临床皮肤科评估。自我报告的皮肤症状随VDU暴露增加而增多。基于客观体征和既往病史数据的临床诊断显示与暴露的关联有所减弱。仅基于客观体征的现状诊断未显示与VDU暴露有任何关联。单侧皮疹在暴露组和非暴露组中出现的频率相同。结论是，本调查或任何其他调查均未发现有任何证据反对VDU相关皮肤问题和对电过敏是“20世纪综合征”的另一个方面这一观点。患有这种疾病的个体有可能通过神经源性介质释放对某些刺激产生反应。
