BACKGROUND: Placental mesenchymal dysplasia (PMD) is a rare vascular and connective placental anomaly, which is often associated with severe fetal and/or maternal complications. The diversity of presentation of PMD challenges diagnosis and effective pregnancy management. OBJECTIVE: We aimed to review cases presenting at 7 tertiary centers worldwide over the last decade and to study the occurrence of obstetric and neonatal complications. STUDY DESIGN: Pathology databases from 7 tertiary hospitals were screened for cases of PMD (between 2007-2017)...

Fetal growth restriction (FGR) the leading cause of perinatal mortality and morbidity is highly related to abnormal placental development, and placentas from FGR pregnancies are often characterized by increased inflammation. However, the mechanisms of FGR-associated inflammation are far from being understood. NLRP7, a member of a family of receptors involved in the innate immune responses, has been shown to be associated with gestational trophoblastic diseases. Here, we characterized the expression and the functional role of NLRP7 in the placenta and investigated its involvement in the pathogenesis of FGR...

INTRODUCTION: Preeclampsia (PE) is one of the leading causes of maternal and fetal mortality globally. The imbalance of trophoblast homeostasis is closely linked with the pathogenesis of PE. MicroRNA-423-5p (miR-423-5p) has been reported to be abnormally expressed in placenta and blood plasma of pregnant women with PE. In the present study, miR-423-5p expression in blood plasma of pregnant women with PE and healthy pregnant women was detected. Also, the roles and molecular mechanisms of miR-423-5p in the development of trophoblast cells were further investigated...

Placenta accreta spectrum (PAS) is a complex obstetric complication associated with high maternal morbidity. Several prenatal ultrasound signs of PAS were reported: mainly the disappearance of the normal uteroplacental interface (clear zone), extreme thinning of the underlying myometrium, and vascular changes within the placenta (lacunae) and placental bed (hypervascularity).1, 2 The ability of the ultrasound to detect PAS is dependent upon several factors, such as operator experience, gestational age at assessment, number of abnormal ultrasound findings, and actual degree of placental invasion...

Thank you for your comments on our manuscript (1). In the letter by Levin et al (2), he wrote that a well designed study should include a large sample size to achieve a high enough power referencing Eshkoli et al (3). This paper has an n=139 as the study group which included cases of clinically diagnosed placenta accreta, and an n=34,000+ which included all the cesarean deliveries during that time period that were not associated with placenta accreta. This paper sought to evaluate risk factors for placenta accreta and found that placenta previa is an independent risk factor...

The term "morbidly adherent placenta" has recently been introduced to describe the spectrum of disorders including placenta accreta, increta and percreta. Due to excessive invasion of the placenta into the uterus there is associated significant maternal morbidity and mortality. Most significant risk factors for morbidly adherent placenta include history of prior cesarean delivery as well as placenta previa in the current pregnancy. Ultrasound remains the gold standard for antenatal diagnosis, however, in recent years MRI has assisted in identifying complex parametrial involvement...

Preeclampsia (PE) is a leading cause of maternal and perinatal death. Accumulated evidence suggests that many long non-coding RNAs (lncRNAs) abnormally expressed in placentas from PE patients, and they may play functional roles in the development of PE. The present study aimed to investigate the functional role TUG1 in PE and explore the potential molecular mechanisms. Clinically, the expression of TUG1 in placental tissues from PE and normal controls were determined. In vitro, human trophoblast HTR-8/SVneo and JAR cells were employed for loss or gain-of-function assays...

OBJECTIVE: While surgical management is the treatment of choice for abnormally invasive placenta, the role of supracervical hysterectomy in this setting is not well established. We aimed to compare supracervical versus total cesarean hysterectomy as a surgical option for abnormally invasive placenta. METHODS: We carried out a 8-year retrospective case-control study. Six cases of patient treated by total hysterectomy were matched and compared to 30 controls treated by supracervical hysterectomy...

Placenta accreta spectrum (PAS) disorders is a multifactorial process that encompasses a heterogeneous group of conditions characterized by an abnormal invasion of trophoblastic tissue through the myometrium and uterine serosa. PAS is associated with a high burden of adverse maternal outcomes including severe life-threatening hemorrhage, need for blood transfusion, damage to adjacent organs, and death. Prenatal screening of PAS is mandatory so that women may be counselled about the severity of this condition to plan management with a multidisciplinary team and delivery in a specialized center...

STUDY QUESTION: Does the upregulation of the zinc finger E-box binding homeobox 2 (ZEB2) transcription factor in human trophoblast cells lead to alterations in gene expression consistent with an epithelial-mesenchymal transition (EMT) and a consequent increase in invasiveness? SUMMARY ANSWER: Overexpression of ZEB2 results in an epithelial-mesenchymal shift in gene expression accompanied by a substantial increase in invasive capacity of human trophoblast cells. WHAT IS KNOWN ALREADY: In-vivo results have shown that cytotrophoblast differentiation into extravillous trophoblast involves an epithelial-mesenchymal transition...

AIMS: To compare the maternal and newborn outcome between cases that underwent conservative surgery with uterine preservation (Group A) to cesarean hysterectomy (Group B). BACKGROUND: Placenta accreta defines abnormally adherent and invasive placentation into the myometrium and in some cases invades adjacent organs. In recent years the incidence of placenta accreta cases has risen due to the increasing prevalence of cesarean delivery. The clinical manifestation of placenta accreta might be life threatening maternal bleeding during the attempt to detach the placenta following delivery...

We present the case of a midtrimester intrauterine foetal demise (IUFD) in the context of abnormally invasive placentation. This was a grade 4 placenta previa with placenta increta in a patient requesting fertility conservation and was managed conservatively without immediate surgical intervention. The patient spontaneously delivered the fetus after 33 days, followed by a large obstetric haemorrhage requiring immediate laparotomy and hysterotomy. Her uterus was preserved and she went on to recover without further significant complication...
