Transient zinc deficiency in a breast-fed premature infant.

Symptomatic zinc deficiency developed in a breast-fed premature male infant of 31 weeks gestation. At 13 weeks of age he presented with diarrhoea, irritability and an eruption identical to acrodermatitis enteropathica. Breast milk zinc concentrations were low. His course was complicated by milk protein intolerance. After 7 weeks, zinc supplementation was ceased without recurrence of disease.
