Beckwith Wiedemann syndrome is a complex developmental disorder characterized by somatic overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycemia, and predisposition to embryonal tumors. We present epidemiological and clinical aspects of patients with Beckwith Wiedemann syndrome diagnosed prenatally or in the early years of life, using data from EUROCAT (European Surveillance of Congenital Anomalies) registries. The study population consisted of 371 cases identified between January 1990 and December 2015 in 34 registries from 16 European countries...

Fetal movements (FM) are a key factor in clinical management of high-risk pregnancies such as fetal growth restriction. While maternal perception of reduced FM can trigger self-referral to obstetric services, maternal sensation is highly subjective. Objective, reliable monitoring of fetal movement patterns outside clinical environs is not currently possible. A wearable and non-transmitting system capable of sensing fetal movements over extended periods of time would be extremely valuable, not only for monitoring individual fetal health, but also for establishing normal levels of movement in the population at large...

We aimed to study the association between three different methods of assessing the amount of amniotic fluid (subjective method (SM), deepest vertical pocket (DVP) and amniotic fluid index (AFI)) and estimated fetal weight (EFW) (in percentile or Z-score) after adjustment on maternal-fetal parameters. We performed a nationwide cross-sectional study through the French network of obstetric sonographers using the "flash" study method and including low-risk singleton pregnancies from 18-40 weeks. Crude and adjusted odds ratio were computed after stratification upon 2nd and 3rd trimester of pregnancy...

BACKGROUND Mycophenolate mofetil (MMF) is one of the most commonly prescribed drugs to prevent organ transplant rejection in combination with calcineurin inhibitors and steroids. It has a different toxicity profile than tacrolimus and cyclosporine.  Gastrointestinal tract disturbances are the most common adverse effects. The use of MMF in pregnant women, however, holds great risk of miscarriage and fetal development defects such as external ear malformation, ocular anomalies, cleft lip and palate, and abnormality of distal limbs, heart, esophagus, and kidneys...

Ventriculomegaly is defined as dilation of the fetal cerebral ventricles and is a relatively common finding on prenatal ultrasound. The purpose of this document is to review the diagnosis, evaluation, and management of mild fetal ventriculomegaly. When enlargement of the lateral ventricles (≥10 mm) is identified, a thorough evaluation should be performed, including detailed sonographic evaluation of fetal anatomy, amniocentesis for karyotype and chromosomal microarray analysis (CMA), and a workup for fetal infection...

Technological progress in medicine has provided earlier diagnosis, even in the prenatal period. We address ultrasonographic imaging of the prenatal eye and orbit. During development of these structures, multiple pathologies and diseases can arise. Orbital anomalies can be detected prenatally using ultrasound or MRI. Some of these include congenital cataracts, hypertelorism, hypotelorism, dacryocystocele, microphthalmia, anophthalmia, orbital tumors/masses, and septo-optic dysplasia. We describe characteristic ultrasound findings of these diseases...

Background: Fetal intracranial injury is a potentially devastating sequelae of maternal trauma, but there is little guidance regarding fetal evaluation in this setting. Case: A 23-year-old woman at 27-week gestation was admitted after a high-speed motor vehicle accident. The initial obstetrical ultrasound was unremarkable, but persistently minimal fetal heart rate variability was observed. Ultrasound on day 3 after the accident showed an intracranial hyperechogenic lesion and subdural fluid collection...

OBJECTIVE: Preterm labor is one of the most significant obstetric problems associated with high rate of actual and long-term perinatal complications. Despite the creation of scoring systems, uterine activity monitoring, cervical ultrasound and several biochemical markers, the prediction and prevention of preterm labor is still a matter of concern. The aim of this study was to examine cervical findings for the prediction and the comparative use of Arabin pessary or cerclage for the prevention of preterm birth in asymptomatic women with high risk factors for preterm labor...

BACKGROUND: Impaired healing of the uterine scar after cesarean has been associated with adverse gynecological and obstetric outcomes. Although a large number of studies have been conducted on the events leading to this, information obtained from prospective randomized studies examining the role of suture material in the formation of cesarean scar defect (CSD) is lacking. OBJECTIVE: To evaluate the effects of synthetic suture materials on CSD formation. STUDY DESIGN: We performed a two-arm 1:1 randomized study in women with singleton pregnancies undergoing elective primary cesarean delivery after the 38th week of gestation...

Over the past decade, ultrasound simulators have been increasingly used as an adjunct to clinical training in Obstetrics and Gynaecology. Studies have shown that providing initial simulation-based ultrasound training leads to sustained improvements in clinical performances1 including improved diagnostic accuracy,2 reduced need for supervised practice, and decreased patient discomfort.3 .

Ultrasound has become a core skill in many specialties. We evaluated the learning and assessment of ultrasound skills in Obstetrics-Gynaecology in a series of eight studies. In the clinical setting, we found that trainees as well as experienced clinicians struggle with technical aspects of performance such as image optimization. We examined how to improve these aspects of performance in the simulated setting by determining mastery learning levels and exploring learning curves for novices. We then examined how to improve the efficiency of training as well as transfer of learning through the use of dyad practice as compared with single practice...

OBJECTIVE: Twin pregnancy is associated with 2-3 fold increased risk of stillbirth compared to singletons. Despite the fact that the growth pattern has been shown to differ in twins compared to singletons, it is controversial whether twin-specific growth charts should be routinely used. A major goal of prenatal ultrasound is to identify fetuses suffering from growth restriction at risk of stillbirth. The main aim of this study was to compare the performance of chorionicity-specific twin charts with singleton charts, both customized and non-customized, in the antenatal prediction of small-for-gestational age (SGA) stillborn and liveborn fetuses...
