[Skin changes in alimentary zinc deficiency caused by artificial infant food].

We report on 2 non-related newborn children who developed erythematosquamous skin eruptions on both their faces and the extensor sides of their fingers at the 4th and 10th week after birth, resp. Both children had been fed upon hypoallergenic formulas since birth. Serum investigations revealed decreased zinc levels: 0.4 and 0.17 mg/l, resp. (normal values: 0.59-0.96 mg/l). Following zinc substitution with zinc sulphate 10 mg daily for 3 days, the serum zinc levels of both children had increased to normal values and remained stationary during continued treatment with 3 mg zinc daily. The skin eruptions disappeared a few days after the start of treatment.
