Maternal antenatal body mass index gains as predictors of large-for-gestational-age infants and cesarean deliveries in Japanese singleton pregnancies.
Greater antenatal weight or body mass index (BMI) gains may lead to larger fetuses and thus increase the risk for operative deliveries, such as cesarean deliveries. In order to examine the effect of weekly maternal weight and BMI changes on large-for-gestational-age (LGA) infants and cesarean delivery, delivery records from overall healthy women were analyzed. ⋯ Applying BMI gains per week enables target weight gains to be set according to the mother's height, which may be useful in reducing risks for LGA and cesarean delivery, especially in shorter women. Further investigation may be needed to explore the practicality and effectiveness of advising women to gain weight according to their body height.

Case ReportsRhabdomyolysis caused by tocolytic therapy with oral ritodrine hydrochloride in a pregnant woman with placenta previa.
Oral-ritodrine-hydrochloride-induced rhabdomyolysis is rare. We report a case of oral-ritodrine-hydrochloride-induced rhabdomyolysis in a pregnant woman with placenta previa without neuromuscular disorders. The patient was a 30-year-old, Japanese primigravida woman, who became pregnant spontaneously. ⋯ An emergency cesarean section was carried out. After delivery, the laboratory data improved gradually with the CK levels at 107 IU/L. If patients complain of muscular symptoms following oral ritodrine hydrochloride use, physicians should consider rhabdomyolysis.

Optimal gestational age of delivery to decrease neonatal morbidity in preterm pregnancies in Korea.
Preterm birth is the most common cause of neonatal morbidity and mortality. Neonatal morbidity and mortality are known to decrease significantly after 34 weeks in preterm births following preterm labor, and after 32 weeks in preterm births following preterm rupture of the membranes. However, these outcomes may not apply to Korean preterm neonates. This study analyzed the morbidity of preterm neonates based on gestational age to determine the optimal gestational age of delivery following preterm labor. ⋯ The optimal gestational age for decreasing the morbidity of major complications in preterm neonates was 1 week later than the American College of Obstetricians and Gynecologists recommendations. For Korean mothers with preterm labor, delivery needs to be delayed until 35 weeks in singletons, 33 weeks in twins, and 32 weeks in singletons with preterm rupture of the membranes.
