BACKGROUND: Neutrophils are the most abundant white blood cells found in the amniotic cavity of women with intraamniotic infection and/or inflammation. The current belief is that these neutrophils are of fetal origin. However, abundant neutrophils have been found in the amniotic fluid of women with a severe acute maternal inflammatory response but without a fetal inflammatory response in the placenta, suggesting that these innate immune cells can also be of maternal origin or a mixture of both fetal and maternal neutrophils...

There are multiple etiologies for fetal dilated bowel loops on ultrasonography (US), and we present a unique case of male siblings with a forkhead box P3 (FOXP3) mutation. Both children presented with fetal bowel anomalies on prenatal US. Family histories of cystic fibrosis and immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome were reported. Amniocentesis in both pregnancies identified a normal male karyotype and the familial mutation associated with IPEX syndrome. IPEX syndrome is one of a group of conditions known as congenital diarrhea disorders...

Expanded carrier screening (ECS) analyzes dozens or hundreds of recessive genes to determine reproductive risk. Data on the clinical utility of screening conditions beyond professional guidelines are scarce. Individuals underwent ECS for up to 110 genes. Five-hundred thirty-seven at-risk couples (ARC), those in which both partners carry the same recessive disease, were invited to participate in a retrospective IRB-approved survey of their reproductive decision making after receiving ECS results. Sixty-four eligible ARC completed the survey...

Context: Resistance to thyroid hormone beta (RTHβ) is an autosomal dominant disorder characterized by reduced sensitivity of target tissues to thyroid hormones (TH). Individuals with RTHβ have high TH levels usually due to mutations in the TH receptor beta (THRB) gene. The management of RTHβ during pregnancy is challenging as wild-type (WT) fetuses born to RTHβ mothers have low birth weight and suppressed postnatal TSH, due to intrauterine exposure to excess TH. Objective: To determine birth weight and postnatal TSH of WT fetuses carried by mothers with RTHβ whose fT4 levels were maintained below 20% the upper limit of normal (ULN)...

Anterior abdominal wall defects (AAWD) correspond to a wide spectrum of congenital defects affecting 6.3/10,000 pregnancies. They have in common a closure defect of the anterior abdominal wall and can be fatal or expose the fetus and the neonate (NN) to many complications. This study was based on a retrospective study of 22 cases of AAWD collected between May 2009 and December 2014. Its purpose was to specify the importance of prenatal ultrasonography in the diagnosis and prognosis assessment of these defects...
