BACKGROUND: Chorioamniotic membrane separation (CMS) is a rare finding that is commonly preceded by invasive fetal procedures. The presence of CMS can also be associated with uncommon maternal or fetal conditions as well as preterm delivery, amniotic band syndrome, umbilical cord complications, and fetal and neonatal death. It is classified as a high-risk antepartum condition due to the significant fetal morbidity and mortality that may ensue. CASE REPORT: A 40-year-old gravida 5 para 1212 at 35 weeks presented for antepartum fetal testing...

Studies have shown that triggering receptor expressed on myeloid cells-1 (TREM-1) is the mediator and activator of neutrophils and monocytes after stimulation with lipopolysaccharide (LPS), heat-inactivated Gram (-) bacteria, Gram (+) bacteria or fungi. Different studies have measured the expression of TREM-1 in patients with bacterial infections and critical states. The purpose of this study was to evaluate the expression of TREM-1 in circulating maternal leukocytes in premature rupture of the membranes (PRM)...

INTRODUCTION: Anomalous cord insertion is associated with increased risk of adverse maternal and perinatal outcome. We aimed to study whether anomalous cord insertion is associated with prelabor rupture of membranes (PROM), preterm PROM (pPROM), long or short umbilical cord, and time trend of spontaneous preterm birth (SPTB) and anomalous cord insertion. MATERIAL AND METHODS: A population-based register study using data from the Medical Birth Register of Norway including all singleton births (gestational age >16 weeks and <45 weeks) during the period 1999-2013 (n=860465) to calculate odds ratios (ORs) for PROM, pPROM, SPTB, and cord length (>95(th) or <5(th) centile) according to the cord insertion site by logistic regression with adjustment for possible confounders...

Rupture of fetal membranes (ROM) can initiate parturition at both term and preterm birth. Apoptosis of the amnion epithelium plays a key role in structural remodeling of the membranes preceding ROM. However, the causative factors for apoptosis remain unidentified. Toward the end of gestation, a feed-forward regeneration of cortisol via 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) exists in the fetal membranes. Here we have examined whether cortisol accumulation is a causative factor for amnion cells apoptosis...

Umbilical cord ulceration is a rare condition presenting with sudden fetal bradycardia due to fetal hemorrhage and in most cases leading to intrauterine death. A strong association with intestinal atresia has been reported. Most cases present after 30 weeks of gestation, with preterm labor or rupture of membranes followed by sudden fetal bradycardia. We report two such cases of umbilical cord ulceration and review the available literature. One of the cases interestingly presented at 26 weeks, much earlier than what is reported in the world literature...
