Placenta previa presents a highest risk to pregnancy, and placenta accreta is the most serious. Placenta accreta requires cesarean delivery and often results in massive obstetric hemorrhage and higher maternal morbidity. Challenges associated with cesarean delivery techniques may contribute to increased maternal blood loss and morbidity rates. Several recent obstetric studies reported the usefu...

Tonicity-responsive enhancer binding protein (TonEBP) is a signal transcription factor of transporters such as sodium-myo-inositol cotransporter (SMIT), aldose reductase. TonEBP has a variety of functions such as control of intracellular osmolytes and immunomodulating. It is known that TonEBP is abundant in the placenta, but location and function aren't known. The aim of this study is to descri...

We report the case of a 36-year old patient in her second pregnancy and hospitalization for metrorrhagia in the third trimester. Suprapubic ultrasound was performed during each hospitalization which showed anterior placenta in the correct location without signs of placental abruption. On her third hospitalization, at 36 weeks of pregnancy, transvaginal ultrasound was performed. It showed an ech...

Matrotrophic fish in the genus Poeciliopsis (Poeciliidae) have a placenta-like structure used in postfertilization maternal provisioning of the developing embryo. To understand better the structure and function of the Poeciliopsis placenta, we derived cDNA libraries from the maternal follicular placenta of 2 matrotrophic Poeciliopsis sister species, P. turneri and P. presidionis. These species ...

Infection with Listeria monocytogenes is a significant health problem during pregnancy. This study evaluates the role of trafficking between maternal organs and placenta in a pregnant guinea pig model of listeriosis. After intravenous inoculation of guinea pigs, the initial ratio of bacteria in maternal organs to placenta was 10(3)-10(4):1. Rapid increase of bacteria in the placenta changed the...

Placenta percreta causing second trimester, spontaneous uterine rupture in non high risk women is less frequent and fewer cases have been reported in the literature. We report a case of uterine rupture in second trimester of pregnancy due to placenta percreta with non specific symptoms in otherwise uncomplicated pregnancy without any high risk factors. This case report describes the case of you...

Objective: To assess the role of color Doppler as a complementary technique to grayscale in the early detection of placenta accreta. Material and Methods: One hundred and ten pregnant women with confirmed placenta previa complete centralize (after 28 weeks' gestation) were included prospectively into this study. Gray-scale trans abdominal ultrasound examination was performed to detect loss of t...

A retained placenta after delivery can lead to bleeding and infection or other serious complications. There are 2 approaches for managing this condition: one is observation until spontaneous expulsion or resorption of the placenta, the other is active intervention such as manual removal, dilation and evacuation, uterine artery embolization, and hysterectomy. In this study, we investigated cases...

background: we studied the possible advantages of feed-forward control nursing model in the treatment of placenta previa. methods: we enrolled 60 pregnant women who were receiving treatment for expectant placenta previa between january 2010 and january 2016 and randomly divided them into the control group and the observation group with 30 cases in each group. in the control group, we offered sp...

background: measuring of maternal serum pregnancy-associated plasma protein-a (papp-a) in first trimester can be a way for early detection of adverse prenatal outcome due to faulty placenta.objective: the aim was to determination of association between placental thickness in second trimester with low level of papp-a in first trimester.materials and methods: in this cohort study, serum papp-a of...
