nant tumor of the ovary. Current concepts with regard to the histogenesis and histologic criteria for diagnosis of endodermal sinus tumor of the ovary were largely determined on the basis of the work of Teilum.' I have been able to identify only one other reported case of endodermal sinus tumor after the age of 60 years in the literature. Ferracini et al. 2 described an endodermal sinus tumor in a 63-year-old female , but their case is of extraovarian origin. Thus I believe the

Fetal acoustic stimulation in the early intrapartum period as a predictor of subsequent fetal condition Albert P. Sarno, Jr., MAJ, USA, Myoung Ock Ahn, MD, MPH, Jeffrey P. Phelan, MD, and Richard H. Paul, MD Los Angeles, California Fetal acoustic stimulation has recently received much attention in the literature. This study evaluates fetal acoustic stimulation in the early intrapartum period as a predictor of subsequent fetal condition . The study group consisted of 201 patients, approximately 60% of whom had complicated pregnancies. All were in the latent phase of labor with singleton, vertex-presenting fetuses. Gestational age ranged from 37 to 43 weeks. Fourteen of the 201 fetuses (7%) showed a nonreactive response to fetal acoustic stimulation and those fetuses were at significantly greater risk of initial and subsequent abnormal fetal heart rate patterns, meconium staining, and cesarean delivery because of fetal distress and Apgar scores
