Ischemic placental disease is a concept that links intrauterine growth retardation (IUGR) and preeclampsia (PE) back to insufficient remodeling of uterine spiral arteries. The rheological consequences of insufficient remodeling of uterine spiral arteries were hypothesized to mediate the considerably later manifestation of obstetric disease. However, the micro-rheology in the intervillous space (IVS) cannot be examined clinically and rheological animal models of the human IVS do not exist. Thus, an in silico approach was implemented to provide in vivo inaccessible data...

BACKGROUND: Fetal growth restriction is a risk factor for adult cardiovascular disease. Intra-placental gene transfer of human insulin-like growth factor-1 corrects birth weight in our mouse model of fetal growth restriction. This study addresses long term effects of fetal growth restriction on cardiac function and the potential preventive effect of insulin-like growth factor-1. STUDY DESIGN: Laparotomy was performed on pregnant C57BL/6J mice at embryonic day 18 and pups were divided into 3 groups: Sham operated; fetal growth restriction (induced by mesenteric uterine artery ligation); treatment (intra-placental injection of insulin-like growth factor-1 after uterine artery ligation)...

Uterine stress is associated with an increased risk of later life metabolic diseases. In this study, we investigated the effect of diesel exhaust (DE) exposure in utero on adult susceptibility to atherosclerosis in genetically hyperlipidemic mice. Pregnant apolipoprotein E-deficient mice received either DE exposure (~250-300 μg/m(3) PM2.5 for 6 h/day, 5 days/week) or filtered air (FA) throughout gestation. Treatment effects on litter size and gender distribution were recorded. Plasma cholesterol and triglycerides were measured at 8, 12 and 16 weeks of age...

Secondary postpartum hemorrhage due to an intraperitoneal bleed following a vaginal delivery is extremely rare. We present a case of spontaneous rupture of the uterine artery following a normal vaginal delivery with a delayed presentation, which resulted in significant morbidity. This case discusses the presentation and management of this rare obstetrical emergency. The report also discusses the role of selective arterial embolization in management of secondary postpartum hemorrhage.

Pyomyoma is an unusual complication of leiomyoma, occurring most commonly in the postpartum, postabortal, and post-menopausal periods. It develops due to infection in necrotic foci within leiomyoma, which is more common during pregnancy due to rapid growth, and in postmenopausal women due to vascular insufficiency. Other contributing factors are curettage, gynecological surgery, cervical stenosis, immunodeficiency, and recently, uterine artery embolization. It presents with a typical triad of sepsis, leiomyoma, and absence of any apparent source of infection...
