Prostaglandin synthesis inhibition in persistent pulmonary hypertension of the newborn.

The data implicating prostaglandin synthesis inhibitors as an etiology for PPHN are reviewed. Consideration is given to the pharmacology of prostaglandin synthesis inhibitors in the fetus and newborn, the role of prostaglandins in the fetal and neonatal circulation, and the effect of closure of the ductus arteriosus on the fetal pulmonary vasculature.

Relative hyperglucagonemia in L-asparaginase-and prednisone-induced glucose intolerance in management of acute lymphocytic leukemia.

Ten children with acute lymphocytic leukemia developed transient diabetes mellitus during treatment with L-asparaginase and prednisone. Serum glucose, plasma insulin, and plasma glucagon levels were measured when the patients were hyperglycemic. Six of the children were restudied several months later when there were no clinical or laboratory signs of glucose intolerance. Hyperglycemia induced by L-asparaginase and prednisone was associated with depression of plasma insulin and, despite the inhibiting action of L-asparaginase on protein synthesis, a corresponding elevation of plasma glucagon. Thus patients with diabetes mellitus induced by L-asparaginase and prednisone have relative hyperglucagonemia similar to other patients with diabetes mellitus.
