Case Reports
Persistent pulmonary hypertension after maternal naproxen ingestion in a term newborn: a case report.
Constricting effect of indomethacin on the ductus arteriosus of the fetus is well known. The fetal effects of other nonsteroid anti-inflammatory drugs (NSAIDs) like naproxen are not well reported. We report here a case of a 3,790-g term neonate who developed persistent pulmonary hypertension after birth with a closed ductus arteriosus. ⋯ The course of illness was progressively better on conservative management. Like indomethacin, other NSAIDs can also cause premature closure of fetal ductus arteriosus, pulmonary hypertension, and life-threatening problems to the neonate. Patient education regarding over-the-counter pain medication during pregnancy should be emphasized.

Review Case Reports
Factor VII deficiency detected in pregnancy: a case report.
Factor VII deficiency is a rare hereditary coagulation disorder with an incidence estimated at 1 in 500,000 individuals. In this report, we describe the 13th case in pregnancy. The diagnosis of severe factor VII deficiency (factor VII level <5%) was established at 10 weeks' gestation after initial laboratory testing showed a markedly prolonged prothrombin time and a normal activated partial thromboplastin time. ⋯ There was no postpartum hemorrhage and mother and newborn were discharged in good condition. The patient's postpartum level of factor VII remained undetectable. Two aspects are outlined: the absence of any significant increase in factor VII clotting activity during this pregnancy and the need to give replacement therapy at labor in patients with severe factor VII deficiency to decrease the risk of postpartum hemorrhage.

Comparative Study Clinical Trial Controlled Clinical Trial
Indomethacin and corticosteroids: an additive constrictive effect on the fetal ductus arteriosus.
The objective of this paper is to study the possible additive effect of corticosteroids to the known effect of indomethacin on potency of the human ductus arteriosus. Systolic and diastolic blood flow of the fetal ductus arteriosus was measured by echo Doppler at 26-32 weeks of gestation. Four groups of patients were studied according to the treatment they have received: group A (exposure to indomethacin and betamethasone); group B (indomethacin alone); group C (betamethasone); and group D (controls). ⋯ No long-term sequella was noted in the infants in whom ductal constriction had been noted in utero. Corticosteroids and indomethacin have a synergistic effect on the frequency and severity of fetal ductus arteriosus constriction. In short-term treatment this effect is transient, and has no deleterious effects on fetal and neonatal cardiac function.

Case Reports
Disorders of maternal calcium metabolism implicated by abnormal calcium metabolism in the neonate.
Normal fetal and neonatal calcium homeostasis is dependent upon an adequate supply of calcium from maternal sources. Both maternal hypercalcemia and hypocalcemia can cause metabolic bone disease or disorders of calcium homeostasis in neonates. Maternal hypercalcemia can suppress fetal parathyroid function and cause neonatal hypocalcemia. ⋯ N. meet the diagnostic criteria for familial benign hypercalcemia. These cases illustrate the important relationships between maternal serum calcium levels and neonatal calcium homeostasis. They emphasize the need to assess maternal calcium levels when infants are born with abnormal serum calcium levels or metabolic bone disease.

Sacrococcygeal teratoma is the most common fetal neoplasm, with an incidence of 1 in 40,000 births. Fetuses with this malformation are at risk for significant perinatal morbidity and mortality. We identified nine fetuses with sacrococcygeal teratomas that were diagnosed antenatally and managed at the University of North Carolina Hospitals over a 7-year period. ⋯ Diagnosis at an early gestational age, development of fetal hydrops, and premature delivery predicted a poor prognosis. When possible, we recommend that delivery be delayed to allow for fetal development. Stabilization of the infant should be attempted before resection of the teratoma.
