A discordant twin gestation, in which one fetus is significantly growth restricted, compared to the other normal twin, is a unique model that can be used to elucidate the mechanism(s) by which the intrauterine environment affects fetal growth. In many model systems, placental transcription factor genes regulate fetal growth. Transcription factors regulate growth through their activation or repression of downstream target genes that mediate important cell functions. The objective of this study was to determine the expression of the placental HLX homeobox gene transcription factor and its downstream target genes in dizygotic twins with growth discordance...

Persistent Hyperplastic Primary Vitreous (PHPV), now-a-days referred to as Persistent Fetal Vasculature (PFV), is a rare congenital anomaly of the eye that typically presents unilaterally with white pupillary reflex and microphthalmia without systemic associations. Bilateral presentations are rare. Here we report a case of 15-year-old male with bilateral PFV without leucokoria who was misdiagnosed as congenital esotropia with amblyopia, treated for refractive errors and referred to higher centre for squint corrections...

OBJECTIVE: Anti-inflammatory substances that inhibit the synthesis of prostaglandins, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and polyphenol-rich foods, can cause constriction of the fetal ductus arteriosus. This study aimed to test the hypothesis that reversal of fetal ductal constriction after maternal restriction of polyphenol-rich foods, in the third trimester of pregnancy, is accompanied by increased prostaglandin E2(PGE2) plasma levels. METHOD: A controlled clinical trial was designed...

INTRODUCTION: Current classification of hypertensive disorders of pregnancy (HDP) is mostly based on temporal classification differentiating HDP according to early and late onset of the disease. However, epidemiological and clinical data suggest that there are two different clinical phenotypes of HDP that coexist at any gestational age: HDP associated to intrauterine growth restriction (HDP-IUGR) and HDP associated to appropriate for gestational age fetal growth (HDP-AGAf). The aim of the study was to evaluate the association of first trimester uterine arteries (UtA) by Doppler velocimetry, and maternal risk factors with HDP according to two different classifications: one based on gestational age at delivery (early- and late-HDP), and one based on longitudinal ultrasound evaluation of fetal growth (HDP-IUGR and HDP-AGAf), independently of the gestational age...

The aim of this pictorial review is to describe the technical advances achieved through the application of 4-dimensional (4D) ultrasound using spatiotemporal image correlation (STIC) over conventional 2-dimensional ultrasound in the prenatal detection of congenital heart disease (CHD). Spatiotemporal image correlation is a volume imaging technique that simplifies fetal heart studies while providing more diagnostic information than is typically available from traditional 2-dimensional studies. Four-dimensional software allows the study of cardiac anatomy and function during a single cardiac cycle and has greatly contributed to diagnostic enhancement of CHD...
