The prognosis in idiopathic hypercalcaemia of infants

Abstract

Thirteen cases of the simple type of idiopathic hypercalcaemia of infants have been followed up for three to six years after the onset of the illness. All the children are in good health and all except one are mentally normal, the one exception having certain features suggesting a syndrome intermediate between the simple and severe types. In all cases the abnormal biochemical findings originally present have disappeared. Simple tests of renal function performed two to five years after the onset did not indicate any residual impairment of renal function. Although the hypercalcaemic episode caused a marked deviation of the weight curve in nearly every child, the height and weight charts indicate that subsequent progress has been satisfactory.
