OBJECTIVE: To compare morbidity among small-for-gestational-age (SGA; birth weight less than the 10th percentile for gestational age), appropriate-for-gestational-age (AGA; birth weight 10th to 90th percentile; reference group), and large-for-gestational-age (LGA; birth weight greater than the 90th percentile) neonates in apparently uncomplicated pregnancies at term (37 weeks of gestation or greater). METHODS: This secondary analysis, derived from an observational obstetric cohort of 115,502 deliveries, included women with apparently uncomplicated pregnancies of nonanomalous singletons who had confirmatory ultrasound dating no later than the second trimester and who delivered between 37 0/7 and 42 6/7 weeks of gestation...

AIM: This study estimated the urinary tract infection (UTI) risk in a nationwide cohort of infants prenatally diagnosed with parenchymal kidney anomalies compared with a comparison cohort. METHODS: A Danish population-based nationwide cohort of fetuses diagnosed with parenchymal kidney anomalies between 2007 and 2012 had previously been identified. These were compared with fetuses without kidney anomalies who were prenatally scanned the same year. Live born infants were followed from birth until the diagnosis of UTI, emigration, death or two years of age...

Tissue harmonic imaging has been widely used in abdominal imaging because of its significant reduction in acoustic noise compared with fundamental imaging. However, tissue harmonic imaging can be limited by both signal-to-noise ratio and penetration depth during clinical imaging, resulting in decreased diagnostic utility. A logical approach would be to increase the source pressure, but the in situ pressures used in diagnostic ultrasound are subject to a de facto upper limit based on the U.S. Food and Drug Administration guideline for the mechanical index (<1...

Vici syndrome is one of the most extensive inherited human multisystem disorders and due to recessive mutations in EPG5 encoding a key autophagy regulator with a crucial role in autophagosome-lysosome fusion. The condition presents usually early in life, with features of severe global developmental delay, profound failure to thrive, (acquired) microcephaly, callosal agenesis, cataracts, cardiomyopathy, hypopigmentation, and combined immunodeficiency. Clinical course is variable but usually progressive and associated with high mortality...

Perinatal autopsy remains the gold-standard procedure used to establish the fetal, neonatal or infant abnormalities. Progressively, perinatal pathology has become a specialized field with important roles of audit for fetal prenatal diagnostic tools, in parents counseling regarding future pregnancies, in scientific research, for epidemiology of congenital abnormalities and teaching. The differences between prenatal ultrasound and autopsy reports represent a strong argument for the autopsy examination following termination of pregnancy...

Accurate and timely prenatal diagnosis of spina bifida (SB) is a major goal of modern antenatal care. Prenatal screening for open SB should be first performed at the time of routine first-trimester ultrasound by examining the posterior fossa for obliteration or non-visualization of the fourth ventricle ("intracranial translucency") and cisterna magna. The second step of screening is the second-trimester anatomy scan, at which time the features of the Chiari type II malformation should be looked for, including ventriculomegaly, scalloping of the frontal bones ("lemon" sign), and backward and caudal displacement of the cerebellar vermis with obliteration of the cisterna magna ("banana" sign)...

Stuart Campbell was the first to use the metaphor of the parallel universes discussing the utilization of ultrasound in pregnancy.(1) The controversy around the use of magnetic resonance imaging (MRI) versus sonography to diagnose cerebral malformations is just another example in this regard. In one spatio-temporal continuum fetal neurosonography allows an accurate diagnosis of central nervous system anatomy(2-5) and malformations (6-9) including complex lesions such as commissural anomalies (10, 11) , posterior fossa malformations (12, 13) , disruptions (14-16) , and cortical anomalies(17) ; it performs similarly to magnetic resonance in the second and third trimester(18, 19) ; eventually, it allows a precise diagnosis of many malformations since the first trimester...

BACKGROUND: Monochorionic twin pregnancies are at increased risk of complications due to sharing a single placenta and potentially developing unbalanced vascular anastomoses. Complications include twin-twin transfusion syndrome (TTTS) which affects 10-15% monochorionic twins, and if untreated has a 70-90% perinatal loss rate. We are currently unable to predict which twins will develop complications or to what severity. We have previously shown differences in angiogenic and placental growth factors in maternal blood in pregnancies complicated by TTTS compared to twin pregnancies not complicated by TTTS but matched for gestation...

Neurosonography is a promising technique for prenatal diagnosis, combining features of ultrasound imaging with fetal neurology. The brain is a three-dimensional structure, therefore observing brain structure in the three basic planes (sagittal, coronal and axial) is mandatory. The anterior fontanelle and sagittal suture may serve as acoustic ultrasound windows in the transvaginal brain scan, allowing to obtain high-resolution neuroimages of the intracranial structures. Furthermore, three-dimensional (3D) ultrasound combined with the transvaginal brain approach provides detailed and sophisticated neuroimages...

Assessment of fetal neurobehavior and detection of neurological impairment prenatally has been a great challenge in perinatal medicine. The evolution of four-dimensional (4D) ultrasound not only enabled a better visualization of fetal anatomy but also allowed the study of fetal behavior in real time. Kurjak Antenatal Neurodevelopmental Test (KANET) was developed for the assessment of fetal neurobehavior and the detection of neurological disorders, based on the assessment of the fetus by application of 4D ultrasound in the same way that a neonate is assessed postnatally...
