Currently available prenatal genetic testing options include a bewildering array of tests from which patients, providers, insurers, and various health systems have to select. In many cases, patients or providers undergo or recommend multiple screening tests focused on the same conditions, for fear of missing something, even if the chance of that is very small. In the commentary in this issue of BJOG by Alfirevic and colleagues (Alfirevic Z, et al. BJOG In Press), the authors opine on the relationship between cell free DNA screening (cfDNA) and first trimester anatomy ultrasound...

Vaginal bleeding in the first trimester has wide differential diagnoses, the most common being a normal early intrauterine pregnancy, with other potential causes including spontaneous abortion and ectopic pregnancy. The incidence of ectopic pregnancy is approximately 2% of all reported pregnancies and is one of the leading causes of maternal mortality worldwide. Clinical signs and symptoms of ectopic pregnancy are often nonspecific. History of pelvic pain with bleeding and positive β-human chorionic gonadotropin should raise the possibility of ectopic pregnancy...

OBJECTIVES: to define the pattern of fetal echocardiographic changes associated with isolated pulmonary valve stenosis (PS) and to correlate the echocardiographic findings with the neonatal outcome and the need of postnatal pulmonary valvuloplasty within the first 12 months of life. METHODS: a prospective cohort study was designed on 16 fetuses with isolated PS and 48 controls matched by gestational age at scan (+/- 2 weeks). Fetal standard ultrasound and comprehensive echocardiography, which included cardiovascular morphometric parameters, systolic and diastolic functional and timing-measurements, were performed in all cases...

BACKGROUND: In recent years, the superior accuracy of maternal plasma cell-free DNA-based prenatal screening has resulted in >50% national decline in amniocenteses and chorionic villus sampling (CVS), creating new implications for specialist training. OBJECTIVE: To compare the annual figures on amniocenteses and CVS in a tertiary hospital with national population-based trends between 2012 and 2015. METHODS: Retrospective study examining the amniocentesis and CVS procedures performed in a tertiary hospital between 2012 and 2015...

BACKGROUND: Down's syndrome occurs when a person has three copies of chromosome 21 (or the specific area of chromosome 21 implicated in causing Down's syndrome) rather than two. It is the commonest congenital cause of mental disability. Non-invasive screening based on biochemical analysis of maternal serum or urine, or fetal ultrasound measurements, allows estimates of the risk of a pregnancy being affected and provides information to guide decisions about definitive testing.  Before agreeing to screening tests, parents need to be fully informed about the risks, benefits and possible consequences of such a test...

BACKGROUND: Down's syndrome occurs when a person has three, rather than two copies of chromosome 21; or the specific area of chromosome 21 implicated in causing Down's syndrome. It is the commonest congenital cause of mental disability and also leads to numerous metabolic and structural problems. It can be life-threatening, or lead to considerable ill health, although some individuals have only mild problems and can lead relatively normal lives. Having a baby with Down's syndrome is likely to have a significant impact on family life...

BACKGROUND: Large mediastinal teratomas in the fetus are rare and can present with direct compression of intrathoracic structures as well as pericardial and pleural effusions. Mediastinal fetal teratoma may be detected as a mass in the chest during a routine prenatal ultrasound. Because of the pressure on mediastinal structures it may result in non-immune fetal hydrops and polyhydramnios. The development of hydrops may lead to fetal demise. Timely obstetric and surgical removal is important to improve survival in this patient population...

OBJECTIVES: To study fetal growth in pregnancies at risk for growth restriction using, for the first time, the Fetal Growth Pathology Score [FGPS1]. METHODS: A retrospective cohort study of growth restriction [GR] was carried out in 184 selected SGA singletons using a novel, composite measure of growth abnormalities termed the FGPS1. Serial fetal biometry was used to establish 2(nd) trimester Rossavik size models and determine FGPS1 values prior to delivery. FGPS1 data were compared to neonatal growth outcomes assessed using Growth Potential Realization Index [GPRI] values [average negative pathological GPRI {av -pGPRI}]...

Natalia Gonzalez, Togas Tulandi
A relatively new type of ectopic pregnancy is cesarean scar pregnancy (CSP). This is related to the increasing number of cesarean deliveries and to the advances in imaging. There are 2 types of CSP; CSP with progression to cervicoisthmic space or uterine cavity (type I, endogenic type) or with deep invasion of scar defect with progression towards bladder and abdominal cavity (type II, exogenic type). The endogenic type of CSP could result in a viable pregnancy; yet with a high risk of bleeding at the placental site...

Objective To evaluate trends in the proportions and outcomes of dichorionic-triamniotic (DT) compared with trichorionic-triamniotic (TT) triplet gestations. Methods This is a retrospective cohort of all triplet gestations identified by first trimester ultrasound at an academic center between 2005 and 2016. Primary outcomes were the change in proportion of DT versus TT triplets over time and the number of fetuses at delivery. Secondary outcomes included differences in mode of conception and maternal/perinatal outcomes by chorionicity...

Anorectal malformations are a rare condition difficult to diagnose in the prenatal period. It can be suspected if distal bowel appears dilated in the first-trimester ultrasound or if intraluminal echogenic foci are detected during the second-trimester scan. We report a case with these ultrasound signs (dilated sigmoid at the first trimester and intraluminal echogenic calcifications at the second trimester), in which a vesicorectal fistula image was obtained. This is the first published prenatal image of a vesicorectal fistula...

Improving micronutrient intakes of under-nourished mothers in low- and middle-income countries increases birth weight, but there is little data on the nature and timing during gestation of any effects on fetal growth. Ultrasound measures of fetal size were used to determine whether and when a food-based supplement affected fetal growth. Non-pregnant women living in Mumbai slums, India (N = 6,513), were randomly assigned to receive either a daily micronutrient-rich snack containing green leafy vegetables, fruit, and milk (treatment) or a snack made from lower-micronutrient vegetables (control) in addition to their usual diet from before pregnancy until delivery...

OBJECTIVE: To assess non-visualization of the choroid plexus of the fourth ventricle (CP-IVV) as a simple, qualitative, and reproducible first-trimester ultrasound feature of the posterior fossa that predicts brain anomalies and chromosomal defects. METHODS: Three-dimensional (3D) ultrasound datasets of the fetal brain were prospectively obtained from 65 consecutive singleton, normal first-trimester fetuses and retrospectively from 27 fetuses identified as having an abnormal fetal posterior fossa on the first-trimester scan, which were randomly included in the final study group...

BACKGROUND: Maternal smoking during pregnancy is linked to reduced birth weight but the gestation at onset of this relationship is not certain. We present a systematic review of the literature describing associations between maternal smoking during pregnancy and ultrasound measurements of fetal size, together with an accompanying meta-analysis. METHODS: Studies were selected from electronic databases (OVID, EMBASE and Google Scholar) that examined associations between maternal smoking or smoke exposure and antenatal fetal ultrasound measurements...

BACKGROUND: Pentalogy of Cantrell (POC) is an extremely rare and complex congenital anomaly. Ultrasound is a valuable, safe, nonionizing, cost effective, widely available, and easily reproducible imaging tool and is indispensible in the diagnosis of POC. Despite the rarity of POC, it is imperative for a radiologist to be aware of its wide spectrum of presentation on ultrasound in first trimester of gestation. Most reported cases in literature till now have been sporadic. In this paper, we aimed to report for the first time in literature, a recurrent case of POC detected in the first trimester in a mother whose previous pregnancy also was terminated in the second trimester medically due to the ultrasound diagnosis of POC...

BACKGROUND: The neonatal development stage of the cerebellum in rats is equivalent to a human foetus in the third trimester of pregnancy. In this stage, cell proliferation, migration, differentiation, and synaptogenesis occur. Clinical and experimental findings have shown that ethanol exposure during brain development causes a variety of disruptions to the brain, including neurogenesis depression, delayed neuronal migration, changes in neurotransmitter synthesis, and neuronal depletion...
