To the Editor:—
Tetany in the new-born has received considerable attention in the recent literature. Some older physicians rather doubted its occurrence except as a clinical curiosity. Recent reports, however, indicate that the incidence of this disorder is on the increase. Why?My interest was aroused in this subject by the occurrence of a dozen cases of convulsions of the new-born in a St. Louis hospital. I examined only one of these infants. In addition to a syndrome characteristic of tetany, edema was also present, and some of the symptoms clearly indicated an increase in the intracranial pressure. It was difficult to exclude the possibility of a late intracranial hemorrhage, and yet the infant completely recovered under the administration of calcium and a change in diet. In this hospital prelacteal feeding was freely used as a routine. The mixture contained lactose 5 per cent and sodium citrate 1 per cent.
