BACKGROUND Placenta accreta/increta/percreta is associated with major pregnancy complications and is thought to be becoming more common. The aims of this study were to estimate the incidence of placenta accreta/increta/percreta in the UK and to investigate and quantify the associated risk factors. METHODS A national case-control study using the UK Obstetric Surveillance System was undertaken,...

Placenta accreta is defined as an abnormal adherence of the placenta to the uterine wall owing to a faulty or an absent decidua basalis. Placenta accreta is further subdivided into placenta accreta vera, increta and percreta, depending on the level of invasion of the uterine wall and surrounding structures. Placenta percreta represents invasion to the serosa and/or other pelvic structures. We h...

Placenta accreta occurs when the deciduas basal is that separates the placental villi from the myometrium is missing. Classification is divided in 3 grades based on histopathologic analysis consisting on: placenta accreta, increate and percent. Placenta accreta occurs when the chorionic villi of the placenta enters in contact with the myometrium. In placenta increta, the chorionic villi invade ...

background: despite the extensive information available in the literature, cell surface marker signature of human amniotic epithelial cells (haecs) remains controversial. the aim of the present study was to characterize immuno-phenotypic features, proliferative capacity and immunogenicity of haecs. we also tested whether expression of some cell surface markers is influenced by the type of tryps...

background: the objective of the study was to evaluate the presence of neospora caninum organisms in the brain of aborted fetuses and placentas of full-term calves born of seropositive cows. methods: during 2006-2007, 12 brains of aborted calves from neospora seropositive cattle and 7 pla­centas from seropositive dams giving birth to full-term calves, from four dairy cattle farms located around...

objective herpes simplex virus (hsv) infection during pregnancy may lead to fetal loss. the aim of this study was to explore the infection rate of hsv type 1 and 2 infection associated with spontaneous abortion in a pilot case-control study in two cities of iran in 2010. patients and methods placenta and curettage samples from 35 healthy full term neonates and 35 cases of spontaneous abortion w...

OBJECTIVE The placenta constitutes a physical and immunological barrier against infectious agents. Toll-like receptors (TLRs) are essential components for the induction of innate immunity responses in different human tissues including the placenta. We investigated the expressions of TLR2 and TLR4 in the decidua and amniotic cells in non-inflamed placenta and placenta with infection. MATERIALS...

The chorioallantoic placenta connects mother and fetus in eutherian pregnancies. In order to understand the evolution of the placenta and provide further understanding of placenta biology, we sequenced the transcriptome of a term placenta of an African elephant (Loxodonta africana) and compared these data with RNA sequence and microarray data from other eutherian placentas including human, mous...

A single placenta normally supports a single fetus. When the situation arises in which two fetuses have to share a single placenta, complications may sometimes develop. Identical twins that share a single placenta are called monochorionic twins (MC). ?Chorion? is the Latin root that refers to the placenta, while the word ?amnion? refers to the sac, or ?membranes? that surround each fetus. While...

Hardly any report exists on the influence of hysteroscopic myomectomy on subsequent pregnancy. Placenta accreta is most often associated with placenta previa in women with multiple prior cesarean sections. We report the first case of placenta accreta without placenta previa during the first pregnancy subsequent to hysteroscopic myomectomy.
