INTRODUCTION: The objective was to assess the prognostic value of the systolic flow through the aortic isthmus in monochorionic pregnancies complicated by twin-twin transfusion syndrome (TTTS) treated by placental laser ablation. MATERIAL AND METHODS: Fetal echocardiography and outcome data of 105 cases of TTTS treated by laser photocoagulation of placental anastomoses were reviewed. Hemodynamic parameters were collected before and after treatment. The isthmic systolic index (ISI) was calculated as the peak systolic velocity/systolic nadir ratio...

OBJECTIVE: Hepatitis is a prevalent infection in developing countries. While hepatitis B and C are deepening their roots in the developed world, hepatitis A and E are common in the developing world. The uniqueness of hepatitis is in its transformation from a relatively self-limiting disease in the non-pregnant state, to a highly virulent disease during pregnancy. MATERIALS AND METHODS: This retrospective observational study was conducted in the Department of Obstetrics and Gynecology, King George's Medical University, Lucknow, for a period of six months from June 2016 to November 2016 [probably during an endemic peak of hepatitis E virus (HEV)] to observe the clinical outcomes in HEV-infected pregnant women...

Although Zika virus (ZIKV)-induced congenital disease occurs more frequently during early stages of pregnancy, its basis remains undefined. Using established type I interferon (IFN)-deficient mouse models of ZIKV transmission in utero, we found that the placenta and fetus were more susceptible to ZIKV infection at earlier gestational stages. Whereas ZIKV infection at embryonic day 6 (E6) resulted in placental insufficiency and fetal demise, infections at midstage (E9) resulted in reduced cranial dimensions, and infection later in pregnancy (E12) caused no apparent fetal disease...

BACKGROUND: Congenital vertical talus is a rare foot anomaly characterized by a prominent calcaneus and rigid forefoot dorsiflexion. While congenital vertical talus has been associated with anomalies such as trisomy 18, myelomeningocele and arthrogryposis, postnatal series have reported cases of isolated congenital vertical talus. OBJECTIVE: The purpose of our study was to determine the incidence of isolated congenital vertical talus prenatally and identify the most common anomalies associated with this finding...

OBJECTIVE: To provide prognostic information to help parents to reach an informed decision about termination or continuation of the pregnancy and to shape peripartum policy based on a large European cohort. METHOD: Thirteen registries from the European Surveillance of Congenital Anomalies (EUROCAT) network contributed data from January 1, 1998 to December 31, 2011. Terminations for fetal anomalies were excluded. Chromosomal anomalies, syndromes and isolated anomaly groups were distinguished according to EUROCAT guidelines...

The increased focus on stillbirth related issues in recent years has brought several previously neglected issues 'out of the shadows' [1] and highlighted the need for greater preventive efforts and better care for bereaved mothers and families. Some issues (such as the option of cesarean delivery for fetal death at late gestation [2], viewing the fetus following pregnancy termination for a fetal anomaly [3,4] and acknowledgement of paternal grief and anxiety [5]) reflect a substantial shift from previous traditions in clinical practice...

OBJECTIVES: To report a cohort of dichorionic triamniotic (DCTA) triplets with access to contemporary fetal interventions. DESIGN: Prospective study. SETTING: A regional referral center for the diagnosis and management of complicated multiple pregnancies. POPULATION: All DCTA triplets receiving consultation and prenatal care at our center from 2010 to 2015. METHODS: The following management alternatives for DCTA were offered: 1) expectant management; 2) reduction of 1 or 2 fetus of the monochorionic component using radio frequency ablation (RFA) after 16 weeks or potassium chloride (KCL) before 16 weeks, respectively; 3) reduction of the isolated fetus using KCL before 16 weeks...

Ductus arteriosus (DA) is a crucial element in the fetal circulation. Therefore, premature constriction of DA during the third trimester can have hazardous complications such as right ventricular dysfunction, fetal heart failure, hydrops, and even in utero demise. Normally, premature constriction is prevented by a balance between prostaglandin E2 and fetal oxygenation. Thus, drugs with antiprostaglandin effects are well-known causes for fetal DA constriction. A similar effect was discovered in eating polyphenol-rich food...

Two cases of devastating fetal malformations associated with vanished monochorionic twins were identified upon review of pathology files. A 35-year-old G1P0 woman and 36-year-old G3P1 woman were both diagnosed with an intrauterine twin gestation via transvaginal ultrasound at 10 weeks. The spectrum of fetal anomalies ranged from omphalocele, bilateral upper extremity, and unilateral lower extremity hypoplasia, to craniofacial malformation with diaphragmatic hernia. On histopathologic examination, the placentas demonstrated vascular anastomoses between the surviving co-twin and the "vanished" fetal sac...

The emergence of Zika virus (ZIKV) and its association with congenital malformations has prompted the rapid development of vaccines. Although efficacy with multiple viral vaccine platforms has been established in animals, no study has addressed protection during pregnancy. We tested in mice two vaccine platforms, a lipid nanoparticle-encapsulated modified mRNA vaccine encoding ZIKV prM and E genes and a live-attenuated ZIKV strain encoding an NS1 protein without glycosylation, for their ability to protect against transmission to the fetus...

INTRODUCTION: The role of neuraxial labor analgesia in perineal trauma following live births is controversial, and no studies have assessed the association in women delivering an intrauterine fetal demise. We evaluated the relationship between neuraxial labor analgesia and perineal laceration in these patients. METHODS: This was a retrospective case-control study of women with a diagnosis of fetal death after 20weeks of gestation, a vaginal delivery, and an Apgar score of 0 at delivery, during the period from January 2007 through December 2015...

BACKGROUND: The efficacy of antenatal corticosteroid treatment for women with threatened preterm birth depends on timely administration within 7 days before delivery. We modelled the probability of delivery within 7 days of admission to hospital among women presenting with threatened preterm birth, using routinely collected clinical characteristics. METHODS: Data from the Canadian Perinatal Network (CPN) were used, 2005-11, including women admitted to hospital with preterm labour, preterm pre-labour rupture of membranes, short cervix without contractions, or dilated cervix or prolapsed membranes without contractions at preterm gestation...

REVIEW
Isaac Blickstein
Single fetal death in a monochorionic twin pregnancy is more frequent than in a dichorionic twin gestation. Due to inter-twin vascular anastomosis in the monochorionic common placenta, the death of one twin causes a drop in blood pressure due to a shift of blood from the survivor to the dead fetus. If the drop of blood pressure is abrupt and serious, the survivor will die soon after (as occurs in 15% of cases). If the drop is less serious, the survivor may sustain ischemic injury (in about 26% of the cases) and if the drop in blood pressure is subtle, the survivor will be intact...

OBJECTIVE: To date, prenatal diagnosis of intracranial hemorrhage (ICH) is mainly based on ultrasound (US) findings rather than magnetic resonance imaging (MRI). We aimed to investigate the role of MRI in the diagnosis of fetal ICH among pregnancies referred to fetal MRI and to characterize the topography of fetal ICH using MRI. METHODS: We retrospectively identified fetal ICH cases diagnosed by MRI from 2008 to 2015 and reviewed their prenatal and postnatal medical records...
