The ex utero intrapartum treatment (EXIT) procedure involves partial delivery of the fetus with the fetal-placental circulation maintained. This allows for management of the obstructed fetal airway via direct laryngoscopy, bronchoscopy, tracheostomy, or surgical intervention. These complex and often challenging procedures have been performed about 100 times in the United ...

Elevated transaminases, hemolysis, and thrombocytopenia in pregnancy are most often caused by a preeclampsia variant-HELLP syndrome (hemolysis, elevated liver enzymes, low platelets). In atypical cases, it is important to consider other causes, such as herpes simplex virus (HSV) hepatitis. Acute interstitial nephritis (AIN)-induced proteinuria can make distinguishing HELLP from its ...

The incidence of ectopic pregnancy in the general population is approximately 1%. This risk increases to 5% following tubal anastomosis. Ectopic pregnancy may cause life-threatening hemorrhage. Morbidity and mortality associated with an extrauterine pregnancy are directly related to the length of time required for diagnosis and treatment. Laparoscopy is the ...

Increased epigenetic variability in the placenta may have evolved in response to its role in mediating the conflicting demands of the mother and fetus. One essential guardian of early pregnancy maintenance is the placental hormone human chorionic gonadotropin (HCG). Among the four primate-specific duplicate HCGβ-coding genes, chorionic gonadotropin-β8 (CGB8) and ...
