Congenital Rickets Presenting with Hypocalcaemic Seizures

At Ataturk University Hospital, eight infants who presented with hypocalcaemic seizures were subsequently found to have rickets. Their mothers had osteomalacia. Neither mothers nor infants received vitamin D supplementation. Maternal vitamin D deficiency and non-supplementation in the infants were causes of rickets in these patients. It is recommended that neonatal hypocalcaemia may be due to maternal vitamin D deficiency and all unsupplemented vitamin D infants presenting with seizures should be investigated for rickets.
