OBJECTIVES By means of hospital-based data over 9 years we sought to evaluate the clinical indications and incidence of emergency peripartum hysterectomy by demographic characteristics and reproductive history. STUDY DESIGN From the obstetric records of all deliveries at Brigham and Women's Hospital between Oct. 1, 1983, and July 31, 1991, we identified(More)
OBJECTIVE The objective of this randomized clinical trial was to test the hypothesis that ultrasonographic screening would significantly alter perinatal outcome as a result of the antenatal detection of fetal congenital malformations. STUDY DESIGN Pregnant women without a specific indication for ultrasonography were randomly assigned to have either two(More)
Two hundred ten consecutive fetuses were identified as having renal pyelectasis among 7400 patients scanned during 1 year. Seven of these 210 fetuses had Down syndrome. We reviewed images of the kidneys of 44 fetuses with Down syndrome collected over 5 years and found that 25% of these affected fetuses had pyelectasis. The incidence of Down syndrome was(More)
We attempted prenatal diagnosis of hemoglobinopathies in 15 cases--11 for beta-thalassemia and four for sickle-cell disease. Fetoscopy was used in seven cases, and placental aspiration in eight. One premature labor, with fetal loss, followed placental aspiration. Globin synthesis was assessed by incubation of samples with 3H-leucine and chain separation on(More)
CONTEXT Two measures traditionally used to examine adequacy of prenatal care indicate that prenatal care utilization remained unchanged through the 1980s and only began to rise slightly in the 1990s. In recent years, new measures have been developed that include a category for women who receive more than the recommended amount of care (intensive(More)
BACKGROUND Many clinicians advocate routine ultrasound screening during pregnancy to detect congenital anomalies, multiple-gestation pregnancies, fetal growth disorders, placental abnormalities, and errors in the estimation of gestational age. However, it is not known whether the detection of these conditions through screening leads to interventions that(More)
Information on demographic characteristics, life-style, and reproductive, prenatal, and medical history was obtained from the prenatal records of 140 women with a preterm delivery (cases) and 280 women with a term delivery (controls) matched by age. Compared with controls, a greater proportion of cases were nonwhite, never married, and educated less than 12(More)
Fetuses with Down's syndrome are more likely than normal fetuses to have a thickened nuchal skin fold and relatively short femurs on ultrasound examination in the second trimester. We evaluated these measures in more than 5500 fetuses, including 28 who were later found to have Down's syndrome by means of amniocentesis with cytogenetic analysis. Normal femur(More)
We describe a patient who had abnormal sonographic findings of the liver 24 hours before signs and symptoms of severe preeclampsia and HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count). The abnormal sonographic appearance of the liver prompted further investigation and was instrumental in the management of this case.
