title: Symptomatic hypocalcemia and hypoparathyroidism in two infants of mothers with hyperparathyroidism and familial benign hypercalcemia.
abstract: Neonatal hypocalcemia secondary to maternal hypercalcemia is relatively rare. We describe two infants with hypocalcemia and generalized seizures at 2 weeks and at 5 days of age, respectively. In the first case the infant was delivered of a mother who was subsequently diagnosed as having hyperparathyroidism. In the second case the infant was a member of a kindred with familial benign hypercalcemia. The evaluation of late-onset neonatal hypocalcemia should include an evaluation of maternal hyperparathyroidism and, in some cases, an evaluation for familial calcium disorders.
