Significant management decisions in triplet pregnancies are made based mainly on ultrasound measurements of fetal growth, although there is a paucity of data examining the accuracy of fetal weight measurements in these gestations. To evaluate accuracy of prenatal ultrasound to diagnose growth abnormalities (intrauterine growth restriction, severe growth discordance) in triplet pregnancies, a retrospective cohort study of 78 triplet pregnancies (234 fetuses) delivered at a single tertiary hospital from January 2004 to May 2015 was performed...

OBJECTIVE: To examine the effect of furosemide on hypertension and edema in patients with pre-eclampsia experiencing high cardiac output. METHODS: The present cohort study enrolled patients with pre-eclampsia who were admitted to the pregnancy pathology unit of the Department of Obstetrics and Gynecology, University of Pécs, Hungary, between January 1 and December 31, 2015. Eligible patients had singleton pregnancies with no fetal anomalies, high blood volume, visible edema, and a hematocrit concentration below 37 L/L...

Dyspigmentation along the Blaschko lines is strongly suggestive of a mosaic skin disorder. We report a 9-year-old male patient who presented with swirls and streaks of both hypo and hyperpigmentation involving the entire body. Additionally, he had hypertrichosis, musculoskeletal and minor neurodevelopment abnormalities but no intellectual disability. Cultured fibroblast displayed trisomy 7 mosaicism, which can explain this pigmentary phenotype. Widespread dyspigmentation associated with involvement of other organs should prompt systemic examination to detect additional anomalies and genetic evaluation should be considered, even with normal fetal karyotype...

OBJECTIVE: It has been reported that gastroschisis is associated with low maternal body mass index (BMI). We tested this hypothesis in the UK. STUDY DESIGN: We studied cases of gastroschisis ascertained from the regional fetal congenital anomaly register. We compared each affected mother with two controls from the birth register and maternity database. The first control was the next mother to deliver in the hospital, representing the normal population of mothers...

: As human cytomegalovirus (HCMV) is the most common infectious cause of fetal anomalies during pregnancy, developing a vaccine that prevents HCMV infection is considered a global health priority. Although HCMV immune correlates of protection are only poorly defined, neutralizing antibodies (NAb) targeting the envelope pentamer complex (PC) composed of subunits gH, gL, UL128, UL130, and UL131A are thought to contribute in preventing HCMV infection. Here, we describe a continuous target sequence within UL128 that is recognized by a previously isolated potent PC-specific NAb, termed 13B5...

OBJECTIVES: To determine reference values for sonography-based estimated fetal weight (EFW) in twin gestations in one single tertiary medical center in the United States. METHODS: A retrospective longitudinal analysis of EFW evaluations of fetuses of twin gestations between November 2006 and June 2016. Fetuses with major congenital anomalies or chromosomal abnormalities were excluded. Estimated fetal weight was calculated using the Hadlock 1985 formula. Linear mixed models were used to allow for multiple but inconsistent observations among individuals, and to account for intertwin differences as well as for gender...

OBJECTIVES: To determine whether fetuses with an isolated aberrant course of the right subclavian artery (ARSA) have increased risk for chromosomal abnormalities, including trisomy 21 or 22q11 deletion. METHODS: We performed a retrospective chart review of all fetuses with antenatally diagnosed ARSA. Data were collected from fetal anatomic surveys, fetal echocardiograms, noninvasive trisomy 21 screening programs, invasive genetic studies, and neonatal records. RESULTS: Seventy-nine fetuses with ARSA were identified at 20...

AIM: To show imaging results from application of four-dimensional (4D) ultrasound lightening technique (HDlive™) in clinical obstetrics practice. METHODS: Normal and abnormal fetuses at second and third trimester of pregnancy undergoing routine scan with 4D HDlive™ (5DUS) in the rendering mode are described. Realistic features of fetal structures were provided by 5DUS in the rendering mode. Normal anatomy as well as pathology like cleft lip, hypoplastic face, micrognathia, low-set ears, corpus callosum, arthrogryposis, aortic arch, left congenital diaphragmatic hernia are highlighted in this study...

We investigated the embryotoxic and fetotoxic effects of Poincianella pyramidalis (Tul.) L.P. Queiroz (syn. Caesalpinia pyramidalis Tul.) leaves on pregnant rats ( Rattus norvegicus). Pregnant rats were divided into 4 groups: G1-fed a ration containing 5% P. pyramidalis leaves beginning on day 1 of pregnancy; G2-fed a ration containing 5% P. pyramidalis leaves commencing on day 6 of pregnancy; G3-fed a ration containing 10% P. pyramidalis leaves starting on day 6 of pregnancy; G4-control group. On day 21 of pregnancy, parameters of reproductive performance were recorded...

Müllerian anomalies are defined as congenital uterine malformations that arise from improperly developing Müllerian ducts. These malformations have a variety of presentations ranging from asymptomatic to amenorrhea, dyspareunia, dysmenorrhea, chronic pelvic pain, pregnancy loss, fetal malpresentation, placental abruption, and intrauterine growth restriction. In this review, we discuss the clinical implications, diagnosis, and treatment of the various Müllerian anomalies focusing on the ones for which clinical intervention is amenable to improve pregnancy outcomes...

Therapeutic fetal surgical procedures are predicated upon the ability to make an accurate fetal diagnosis. The earliest open fetal surgical procedures were introduced in the 1960s to treat Rh isoimmunisation. They were introduced when it became possible to predict impending fetal demise. Open procedures were abandoned when percutaneous approaches proved superior. The introduction of fetal ultrasound allowed the diagnosis of other congenital anomalies, some being amenable to fetal interventions. Open fetal surgical procedures were initially utilised, with significant maternal morbidity...

BACKGROUND: To evaluate the impact of the introduction of prenatal screening on time of detection and pregnancy outcome for trisomy 21 (T21), trisomy 18 (T18) and trisomy 13 (T13). METHODS: We performed a retrospective, population-based cohort study in the Northern Netherlands including 503 trisomy cases born between 2005 and 2012. Screening tests and invasive procedures, timing of diagnosis and pregnancy outcome were compared between the period before (2005-2006) and after introduction (2007-2012) using X (2) tests...

Tumor necrosis factor-α (TNF-α) is a central regulator of inflammation, and TNF-α antagonists may be effective in treating inflammatory disorders in which TNF-α plays a major pathogenic role. TNF-α has also been associated with inflammatory mechanisms related to implantation, placentation, and pregnancy outcome. TNF-α is secreted by immune cells and works by binding to TNFR1 and TNFR2 cell receptors. TNF-α is also related to JAK/STAT pathways, which opens up hypothetical new targets for modifying. The accurate balance between Th1 cytokines, mainly TNF-α, Th17, and Th2, particularly IL-10 is essential to achieve good obstetric outcomes...

OBJECTIVE: Pallister-Killian syndrome (PKS) is a rare, sporadic genetic disorder caused by mosaic tetrasomy of the short arm of chromosome 12 (12p). Clinically, PKS is characterized by several systemic abnormalities, such as intellectual impairment, hearing loss, epilepsy, hypotonia, craniofacial dysmorphism, pigmentary skin anomalies, epilepsy, and a variety of congenital malformations. Prenatally, PKS can be suspected in the presence of ultrasound anomalies: diaphragmatic hernia, rhizomelic micromelia, hydrops fetalis, fetal overweight, ventriculomegaly in the central nervous system, congenital heart defects, or absent visualization of the stomach...

Venous anomalies discovered on cardiac implantable electronic device (CIED) implantation may hinder both the insertion of cardiac leads and the selection of their optimal intraventricular placement. Such venous anomalies may be a result of congenital vascular defects, e.g. anomalies of the fetal venous system, or be a consequence of earlier cardio- or thoracosurgical procedures. In the case of the latter, the extent of morphometric changes to mediastinal structures may depend on the extent of prior lung tissue resection...
