BACKGROUND: Gastroschisis is the most common major congenital anomaly managed by paediatric surgeons. The significance of certain associated antenatal ultrasound features in determining fetal outcome is under discussion. AIM: The study aims to define if associated antenatal ultrasound features of gastroschisis are useful prognostic markers for fetal outcome. By establishing the significance of features, including extra- and intra-abdominal bowel dilatation, stomach herniation, stomach dilatation, bowel matting, growth restriction, abnormal umbilical artery (UA) Doppler ultrasounds, and abnormal amniotic fluid volume, it is hoped clinicians will have enhanced ability to counsel parents about the likely outcomes for their infant...

OBJECTIVES: The primary aim of the study was to assess intra-observer and inter-observer reproducibility and generalizability (general reliability) of first trimester Doppler measurements of uterine arteries (UtA) performed both transabdominally (TA) and transvaginally (TV). Secondary aims were to investigate whether maternal BMI and acquisition modality (transabdominal or transvaginal) affect feasibility and reliability of UtA Doppler evaluation. METHODS: Singleton pregnancies between 11(+0) and 13(+6) weeks underwent TA and TV Doppler measurements of UtA prospectively, blindly and independently by Fetal Medicine Foundation-accredited operators...

OBJECTIVE: To generate physical models of fetuses from images obtained with three-dimensional ultrasound (3D-US), magnetic resonance imaging (MRI), and, occasionally, computed tomography (CT), in order to guide additive manufacturing technology. MATERIALS AND METHODS: We used 3D-US images of 31 pregnant women, including 5 who were carrying twins. If abnormalities were detected by 3D-US, both MRI and in some cases CT scans were then immediately performed. The images were then exported to a workstation in DICOM format...

BACKGROUND: Due to the recent outbreak of Zika virus, there has been a newfound interest in fetal and neonatal microcephaly. In 1984, Chervenak et al. proposed criteria for the prenatal ultrasound diagnosis of microcephaly as ≤3 standard deviations (SD) from the mean. Despite improvements in medicine these criteria have not been reevaluated in 30 years. OBJECTIVE: To examine how the original 1984 Chervenak et al. criteria for the diagnosis of fetal microcephaly apply to a current population utilizing modern ultrasound equipment and techniques...

INTRODUCTION: Brain natriuretic peptide (BNP) is synthesized by human fetal membranes, both the amnion and chorion. This locally produced BNP inhibits the contraction of the human myometrium, contributing to the maintenance of myometrial quiescence during pregnancy. Reference values for NT-proBNP concentrations in amniotic fluid at different gestational ages have not been completely defined. We aimed to investigate the range of fetal NT-proBNP values in amniotic fluid in normal pregnancy between 17 and 41weeks of gestation...

The impact factor (IF) for 2015 was recently released and this could be the time to once again reflect on its use as a metric of a journal. Problems and concerns regarding the IF have been addressed extensively elsewhere 1 2. The principle of the IF for a given year is that it represents the average number of citations of articles published in the journal in the two previous years.While authors frequently cite the IF as a determining factor for submission, the IF does not predict how many times individual articles will be cited...

BACKGROUND: Early pregnancy complaints in emergency medicine are common. Emergency physicians (EP) increasingly employ ultrasound (US) in the evaluation of these complaints. As a result, it is likely that rare and important diagnoses will be encountered. We report a case of fetal anencephaly diagnosed by bedside emergency US in a patient presenting with first-trimester vaginal bleeding. CASE REPORT: A 33-year-old patient at 10 weeks gestation presented with vaginal bleeding...
