Seven cases of contact dermatitis in children due to identification bracelets made of polyvinyl chloride plastic are reported. Patch tests with the bracelets were negative in the five cases tested. It is concluded that the reactions were irritant due to some unknown chemical in the bracelets. The most widely used plasticizers in PVC, phthalates, must have very low sensitizing properties, as only one positive patch test was found in 1532 patch tests with phthalate mix, performed as a joint study by the International Contact Dermatitis Research Group.
报告了7例因聚氯乙烯塑料识别手环导致儿童接触性皮炎的病例。对其中5例进行的手环斑贴试验结果为阴性。结论是，这些反应是由手环中某种未知化学物质引起的刺激性反应。聚氯乙烯中使用最广泛的增塑剂邻苯二甲酸盐致敏性肯定非常低，因为在国际接触性皮炎研究小组联合开展的一项研究中，对1532例进行邻苯二甲酸盐混合物斑贴试验时仅发现1例阳性。
