Hepatitis E-Associated Hospitalizations in the United States: 2010-2015 and 2015-2017.

Hepatitis E is considered rare in the United States (US) despite its widespread occurrence in Asian and African countries. The objective of this study was to describe the characteristics of hepatitis E-related pregnancies and acute-on-chronic liver failure and analyse trends for hepatitis E diagnosis among hospitalized patients in the US. We examined data from the 2010-2017 National Inpatient Sample from Healthcare Cost and Utilization Project to determine mortality, morbidity, pregnancy diagnoses, chronic liver disease diagnoses, and other conditions during hospitalization.

Significance of abnormal umbilical artery Doppler studies in normally grown fetuses.

Objective: To determine whether there is a relationship between abnormal umbilical artery Doppler studies (UADS) and small for gestational age (SGA) birth weight and other adverse perinatal outcomes in fetuses that appear normally grown by ultrasound.

Methods: This was a retrospective study of all women who had UADS performed at or after 26 weeks of gestation at our institution between January 2005 and December 2012. Women were excluded if they had a fetal demise, a fetus with growth restriction, a fetus with congenital anomaly, or a multiple gestation.

Prenatal ABO/RHD Genotyping: A New Paradigm to Allow for Fresh Whole Blood for Cardiopulmonary Bypass in the Immediate Newborn Period.

Compared to standard component therapy, fresh whole blood (FWB) offers potential benefits to neonates undergoing cardiopulmonary bypass (CPB) in the context of open cardiac surgery: decreased blood loss and subsequent risk of volume overload, improved coagulation status, higher platelet counts during and following CPB, circumvention of limited vascular access, and significantly reduced donor exposures. Obtaining FWB, however, entails 2-5 days of preparation, which often precludes its availability for neonates requiring CPB in the immediate newborn period. Using a multidisciplinary approach and molecular ABO/RHD genotyping on amniotic fluid, we developed a protocol to allow procurement of FWB for timed delivery followed by open cardiac surgery.

Ultrasound Findings Associated With Antepartum Viral Infection.

This article reviews the sonographic manifestations of fetal infection and the role of ultrasound in the evaluation of the fetus at risk for congenital infection. Several ultrasound findings have been associated with in utero fetal infections. For the patient with a known or suspected fetal infection, sonographic identification of characteristic abnormalities can provide useful information for counseling and perinatal management.

Multidisciplinary consensus on the classification of prenatal and postnatal urinary tract dilation (UTD classification system).

Objective: Urinary tract (UT) dilation is sonographically identified in 1-2% of fetuses and reflects a spectrum of possible uropathies. There is significant variability in the clinical management of individuals with prenatal UT dilation that stems from a paucity of evidence-based information correlating the severity of prenatal UT dilation to postnatal urological pathologies. The lack of correlation between prenatal and postnatal US findings and final urologic diagnosis has been problematic, in large measure because of a lack of consensus and uniformity in defining and classifying UT dilation.

Extracorporeal fetal support: a new animal model with preservation of the placenta.

Background: Previous models of support for premature sheep fetuses have consisted of cesarean delivery followed by catheterization of umbilical or central vessels and support with extracorporeal membrane oxygenation (ECMO). The limitations of these models have been insufficient blood flow, significant fetal edema, and hemorrhage related to anticoagulation.

Methods: We performed a gravid hysterectomy on 13 ewes between 135 and 145days gestational age.

Ex utero intrapartum treatment procedure for management of congenital high airway obstruction syndrome in a vertex/breech twin gestation.

Congenital high airway obstruction syndrome (CHAOS) is one indication for the ex utero intrapartum treatment (EXIT), which is used to secure the fetal airway, while fetal oxygenation is maintained by uteroplacental circulation. We report a successful EXIT procedure in a twin gestation in which one child had CHAOS while the other was a healthy child without any congenital abnormalities. After version of Twin B to allow for delivery of Twin A, Twin B underwent airway evaluation and tracheostomy for laryngeal atresia prior to delivery.

Isolated prenatal choroid plexus cysts do not affect child development.

Objective: To examine the effect of isolated prenatal choroid plexus cysts (CPCs) on child cognitive, behavioral, motor, and autonomic development at 18 months of age.

Methods: A prospective design was implemented to identify CPC cases and controls in mid-pregnancy. Cases (n = 25) and controls (n = 45) participated in a follow-up visit when children were 18 months of age.

Intrahepatic vein for fetal blood sampling: one center's experience.

Objective: The objective of the study was to examine 1 center's experience with fetal blood sampling via the fetal intrahepatic vein (IHV) and cordocentesis.

Study Design: Consecutive IHV and cordocentesis procedures between July 1987 and February 2006 were compared with respect to success rates, streaming at the sampling site, nonreassuring fetal heart rate (NRFHR), or need for urgent delivery post procedure. A subanalysis of cases with fetal thrombocytopenia was performed.

A dilated fetal stomach predicts a complicated postnatal course in cases of prenatally diagnosed gastroschisis.

Objective: The purpose of this study was to determine whether dilation of the fetal stomach is associated with increased perinatal complications in infants with prenatally diagnosed gastroschisis.

Study Design: From 34 newborn infants with gastroschisis who were delivered at our institution over a 10-year period, 2 groups were analyzed on the basis of the presence or absence of a dilated fetal stomach. Reactive versus nonreactive nonstress test results were recorded, when performed.

Fetal anatomic and functional echocardiography: a 5-year review.

Objective: To assess the concordance of fetal and postnatal echocardiography when congenital heart disease is suspected prenatally.

Methods: The perinatology and pediatric cardiology ultrasound databases were searched for fetal echocardiograms obtained between June 1995 and June 2000. All cases with abnormal fetal echocardiographic findings in which postnatal echocardiography was performed were included.
