Extramembranous pregnancy: maternal, placental, and perinatal implications

Obstetrics and Gynecology
M PerlmanA Ornoy


The case of a patient who survived extramembranous pregnancy is presented, and the maternal, fetal, placental, and neonatal features of the condition are described and delineated. Previously underscribed phenomena include clinical evidence of fixed fetal position and a unique pattern of hemosiderin and hematoidin staining of the fetal membranes. The patient described had an intermediate form of the oligohydramnios tetrad following premature rupture of the membranes; the infant survived with respiratory support therapy in spite of apparent partial lung hypoplasia. On the basis of this and previous observations of the outcome of pregnancy complicated by prolonged amniotic fluid leakage, preliminary recommendations for the management of such pregnancies are made.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.
