OBJECTIVE To examine the incidence of pyelonephritis and the incidence of risk factors, microbial pathogens, and obstetric complications in women with acute antepartum pyelonephritis. METHODS For 2 years, information on pregnant women with acute pyelonephritis was collected in a longitudinal study. All women were admitted to the hospital and treated with(More)
There is no clearly established umbilical artery pH cutoff to be used for defining pathologic fetal acidemia (ie, the threshold associated with major neonatal morbidity or mortality). Classically, a pH cutoff of less than 7.20 has been used. Our goal was to define this pH cutoff more precisely. There were 3506 term newborns (2500 g or greater) with an(More)
BACKGROUND At any given gestational age, infants with low birth weight have relatively high morbidity and mortality. It is not known, however, whether there is a threshold weight below which morbidity and mortality are significantly greater, or whether that threshold varies with gestational age. METHODS We analyzed the neonatal outcomes of death,(More)
OBJECTIVE To analyze neonatal mortality and morbidity rates at 34, 35, and 36 weeks of gestation compared with births at term over the past 18 years at our hospital and to estimate the magnitude of increased risk associated with late preterm births compared with births later in gestation. METHODS We performed a retrospective cohort study of births at our(More)
BACKGROUND The 10-point Apgar score has been used to assess the condition and prognosis of newborn infants throughout the world for almost 50 years. Some investigators have proposed that measurement of pH in umbilical-artery blood is a more objective method of assessing newborn infants. METHODS We carried out a retrospective cohort analysis of 151,891(More)
OBJECTIVE Our purpose was to assess whether antepartum oligohydramnios is associated with adverse perinatal outcomes. STUDY DESIGN Women delivered between July 1, 1991, and September 30, 1996, who underwent ultrasonography at >/=34 weeks' gestation were analyzed. Oligohydramnios was defined as an amniotic fluid index </=50 mm. Perinatal outcomes in(More)
OBJECTIVE To test the hypothesis that antenatal dexamethasone treatment to promote fetal lung maturation results in decreased birth weight corrected for gestational age. METHODS The birth weights of all dexamethasone-treated, singleton, live-born infants delivered at our hospital were compared with our overall obstetric population; a group of untreated(More)
OBJECTIVE To establish pregnancy-specific free thyroxine thresholds and to assess perinatal effects associated with isolated maternal hypothyroxinemia identified in the first half of pregnancy. METHODS Stored serum samples from 17,298 women who previously underwent thyroid-stimulating hormone (TSH) screening in the first half of pregnancy were analyzed(More)
OBJECTIVE The purpose of this study was to determine if refraining from coached pushing during the second stage of labor affects postpartum urogynecologic measures of pelvic floor structure and function. STUDY DESIGN Nulliparous women at term were randomized to coached (n = 67) vs uncoached (n = 61) pushing. At 3 months' postpartum women underwent(More)
OBJECTIVE We attempted to determine the frequency of postpartum perineal morbidity (dehiscence, infection, and rectovaginal fistula) in women after fourth-degree perineal repair. STUDY DESIGN The medical records of 390 women at Parkland Memorial Hospital with fourth-degree perineal repair during 1989 and 1990 were retrospectively reviewed in a case-cohort(More)
