Eczema is a frequent childhood manifestation and a few atopic children are allergic to certain foods or aeroallergens. Anxious parents of atopic children often have a fear of topical steroid-related side-effects, and some may try a range of elimination diets to avoid allergies. Elimination diets increase the risk of anaphylaxis on re-exposure to previously tolerated foods from the loss of oral tolerance. Unbalanced diets together with an inadvertent excessive consumption of fruits and vegetables may lead to carotenemia from the carotenoids in the plant foods. Carotenemia is benign but unusual diets and the consumption of preformed vitamin A in health supplements can lead to vitamin A toxicity. We discuss a child with eczema on an exclusion diet presenting with anaphylaxis to dairy food. He had carotenemia with hepatomegaly, which resolved on dietary management.
湿疹是常见的儿童病症，一些特应性儿童会对某些食物或气传变应原过敏。特应性儿童焦虑的父母常常担心局部使用类固醇带来的副作用，有些父母可能会尝试一系列排除饮食法来避免过敏。排除饮食法会增加再次接触先前耐受食物时因失去口服耐受性而发生过敏反应的风险。不均衡的饮食，再加上不经意间过量食用水果和蔬菜，可能会因植物性食物中的类胡萝卜素导致胡萝卜素血症。胡萝卜素血症是良性的，但不寻常的饮食以及在健康补充剂中摄入预制维生素A可能会导致维生素A中毒。我们讨论了一名患有湿疹且正在进行排除饮食的儿童，他对乳制品食物出现过敏反应。他患有胡萝卜素血症并伴有肝肿大，通过饮食管理后症状得到缓解。
