OBJECTIVE The purpose of this study was to determine risk assessments for a spectrum of neonatal outcomes with elective cesarean delivery versus a trial of labor for previous cesarean section and otherwise healthy patients who deliver at term. STUDY DESIGN The perinatal/neonatal database of St. Joseph's Health Care, London, Ontario, Canada, was used to(More)
A total of 275 consecutive patients referred for intravenous urography were monitored for electrocardiographic changes during administration of Conray 400 or Renovist II in the form of either intravenous bolus or infusion. Three patients who received Conray (two bolus and one infusion) developed sustained ventricular tachycardia; they reverted to sinus(More)
OBJECTIVE The aim of this study was to test the null hypothesis that size at birth relative to fetal or neonatal growth standards is not a significant variable related to the risk of spontaneous preterm delivery. STUDY DESIGN This was a hospital-based cohort study of consecutive births at a tertiary care perinatal center from January 1, 1985, to December(More)
OBJECTIVE The purpose of this study was to determine the effect of discordant fetal growth on subsequent perinatal and neonatal outcome for different degrees of birth weight discordance in preterm twin gestations. STUDY DESIGN One hundred twenty-two live born twin sets delivered between 25 and 34 completed weeks' gestation were retrospectively studied.(More)
PURPOSE To determine whether mutations in the FZD4 gene are a risk factor for developing severe ROP. METHODS Three Canadian tertiary care centers recruited premature infants prospectively and retrospectively, and assigned affectation status based on the maximum degree of severity of ROP recorded in both eyes. Mutation screening of the FZD4 gene was(More)
OBJECTIVE This cohort study investigated potential clinical and biochemical predictors of subsequent preterm birth in women presenting with threatened preterm labor. STUDY DESIGN AND SETTING Subjects were 218 pregnant women admitted to hospital with a diagnosis of threatened preterm labor at 22-36 weeks gestation. Exclusion criteria were multiple(More)
OBJECTIVE To evaluate the association between postpartum maternal depressive symptoms or maternal anxiety and health services utilization (HSU) for infants. DESIGN Telephone survey. SETTING London-Middlesex region of Ontario. PARTICIPANTS Mothers of infants 2 to 12 months of age between 2004 and 2005 (N = 655). This sample was drawn from a larger(More)
OBJECTIVE The purpose of this study was to further delineate the impact of preterm chorioamnionitis on a spectrum of neonatal outcomes using a large tertiary hospital population. STUDY DESIGN The perinatal/neonatal and placental pathology databases of St. Joseph's Health Care, London, Ontario, Canada, were used to obtain the umbilical cord gas and pH(More)
BACKGROUND The benefits of breast milk to the newborn infant are well established. The Canadian Paediatric Society recommends exclusive breastfeeding for the first 6 months of life for healthy, term infants. Mothers of premature newborns, however, may have difficulty providing an adequate supply of breast milk. Domperidone is officially used as a prokinetic(More)
Although, in general, twins have higher perinatal mortality rates than singletons, preterm twins have lower perinatal mortality rates than singletons of the same birth weight or gestational age. This study investigated the hypotheses that this paradoxical twin advantage: 1) is due to gestational age distribution differences between the singleton and twin(More)
