地方性缺锌通常被认为是发展中国家一个普遍而严重的问题。然而,这个问题在英国的常规诊疗过程中也可以遇到,而且很容易被忽视。任何原因引起的营养不良同时合并尚未诊断的皮肤问题时,临床医师在作出诊断时都应提高警惕。实验室检查不一定可靠。如果怀疑缺锌,可以进行试验性治疗补充锌,同时也能证实是否缺锌。3例营养不良病案中的患者都是在出现皮肤改变后被诊断缺锌的。2例营养不良由酒精中毒引起,第3例由神经性厌食引起。现就引起缺锌的原因、机理、治疗及锌的动态平衡进行讨论。

Zinc deficiency is generally considered to be a common and serious problem in developing countries. However, this problem can also be encountered during routine medical care in the United Kingdom and can easily be overlooked. Any cause of malnutrition combined with unrecognized skin problems, clinicians should be vigilant in the diagnosis. Laboratory tests may not be reliable. If you suspect zinc deficiency, experimental treatment can be supplemented with zinc, but also to confirm whether zinc deficiency. Three patients with malnutrition were diagnosed with zinc deficiency after skin changes. Two cases of malnutrition caused by alcoholism, the third case caused by anorexia nervosa. Now cause the cause of zinc deficiency, mechanism, treatment and zinc homeostasis are discussed.
