The incidence of morbidly adherent placenta (MAP) has risen 13-fold since the early 1900s and is directly correlated with the rising rate of cesarean delivery. It is important for clinicians to screen all pregnancies for MAP at the time of routine second-trimester ultrasonography. In addition, patients with risk factors (e.g., multiple prior cesarean deliveries) should undergo targeted screening for MAP. Optimal maternal and fetal outcomes for these high-risk pregnancies result from accurate prenatal diagnosis and comprehensive multidisciplinary preparation and delivery between 34 and 36 weeks of gestation...

We analyzed the characteristics of the population with congenital portosystemic shunt diagnosed during the antenatal period and the organization of their perinatal care. This multicentric retrospective study included all the patients with a prenatal diagnosis of congenital portosystemic shunt. Between 1999 and 2015, 12 patients were included. Prenatal diagnosis was done at a median 26.5 weeks of gestation (21-34). All the patients presented intrahepatic CPSS, three of them had associated congenital cardiopathy, and one a Bannayan-Zonana syndrome...

Omphalocele, Exstrophy of cloaca, Imperforate anus and Spinal defects (OEIS) is a severe manifestation of exstrophy-epispadias sequence with a combination of defects including OEIS. It results from improper closure of anterior abdominal wall and defective development of cloaca and urogenital septum due to defect in blastogenesis during the 4(th) week of gestation. Identification of this complex is important through foetal autopsy as this condition can recur in siblings. Prenatal diagnosis also helps to prevent foetal death with appropriate management in the less severe cases...

PURPOSE: First trimester risk assessment plays a major role in the contemporary pregnancy care. It has evolved significantly since its introduction in the 1990s when it essentially consisted of just the nuchal translucency measurement. Today, it involves the measurement of several biophysical and biochemical markers and can assess the risk for a wide array of major chromosomal and non-chromosomal defects as well as other pregnancy-related complications. METHODS: A search of the Medline and Embase databases was done looking for articles about first trimester screening...

BACKGROUND: Congenital fetal cardiac anomalies compromise the most common group of fetal structural anomalies. Several previous reports analyzed all types of fetal cardiac anomalies together without individualized neonatal morbidity outcomes based on cardiac defect. Mode of delivery in cases of fetal cardiac anomalies varies greatly as optimal mode of delivery in these complex cases is unknown. OBJECTIVE: We sought to determine rates of neonatal outcomes for fetal cardiac anomalies and examine the role of attempted route of delivery on neonatal morbidity...

BACKGROUND: Preterm birth is a major paediatric challenge difficult to prevent and with major adverse outcomes. Prenatal stress plays an important role on preterm birth; however, there are few stress-related models to predict preterm birth in women with Threatened Preterm Labor (TPL). OBJECTIVE: The aim of this work is to study the influence of stress biomarkers on time until birth in TPL women. METHODS: Eligible participants were pregnant women between 24 and 31 gestational weeks admitted to the hospital with TPL diagnosis (n=166)...

BACKGROUND: Coarctation of the aorta (CoA) is difficult to diagnose by fetal echocardiogram (F-Echo), often requiring multiple F-Echos during gestation and neonatal echocardiograms (N-Echos) after birth. Furthermore, CoA is the most common ductal-dependent lesion missed on routine physical exam. OBJECTIVES: We sought to determine the most cost-effective diagnostic approach in caring for infants in whom an initial F-Echo is concerning for CoA. METHODS: Four paradigms for management after initial F-Echo could not rule out CoA were compared, with a single paradigm involving additional F-Echos: (1) multiple F-Echos for diagnostic clarity and performance of N-Echo on neonates with remaining high suspicion for CoA on F-Echos (prenatal-multiple), (2) no further F-Echo and performance of N-Echo on neonates with high suspicion for CoA on initial F-Echo (postnatal-selective), (3) no further F-Echo and performance of N-Echo on all neonates (postnatal-all), and (4) no further F-Echo or N-Echo with reliance on routine physical exam to identify afflicted infants (postnatal-none)...

BACKGROUND: Intrauterine exposure to gestational diabetes mellitus (GDM) confers a lifelong increased risk for metabolic and other complex disorders to the offspring. GDM-induced epigenetic modifications modulating gene regulation and persisting into later life are generally assumed to mediate these elevated disease susceptibilities. To identify candidate genes for fetal programming, we compared genome-wide methylation patterns of fetal cord bloods (FCBs) from GDM and control pregnancies...

Aortopulmonary window is a rare cardiac developmental anomaly characterised by a communication between the ascending aorta and the pulmonary artery. Aortopulmonary window may be isolated or associated with cardiac defects such as ventricular septal defect, atrial septal defect, interrupted aortic arch, and tetralogy of Fallot. We report a case of aortopulmonary window associated with aberrant subclavian artery based on fetal two-dimensional echocardiogram. The mother was referred for fetal echocardiography because of multiple fetal anomalies...

OBJECTIVE: Single intrauterine death (sIUD) in twin pregnancy is associated with a significant risk of cotwin demise and preterm birth (PTB), especially in monochorionic (MC) twins. However, it is yet to be established whether the gestational age at loss may influence the pregnancy outcome. The aim of this study was to explore the risk of PTB according to the gestational age at diagnosis of sIUD. METHODS: This was a cohort study of all twin pregnancies booked for antenatal care in a large regional network of nine hospitals over a 10-year period...
