Associative prevention mechanisms can be a method of minimising the risk of developing the disease, within early stages of pregnancy. Placental syndromes include pregnancy loss, fetal growth restriction, preeclampsia, preterm delivery, premature rupture of membranes, placental abruption and intrauterine fetal demise.
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
Histopathology of placenta with increased syncytial knotting of chorionic villi, with two knots pointed out. The following characteristics of placentas have been said to be associated with placental insufficiency, however all of them occur in normal healthy placentas and full term healthy births, so none of them can be used to accurately diagnose placental insufficiency: [citation needed]
VUE occurs in the term placenta, in the late third trimester of pregnancy. Infectious villitis occurs at the early-third to late-second trimester of the pregnancy. Infectious villitis involves a greater part of the placenta (umbilical cord, chorionic plate, membranes) compared to VUE (terminal and stem villi). Histologically VUE is ...
It begins between the 4 and 8 weeks of pregnancy and usually subsides by 14 to 16 weeks. The exact cause of nausea is not fully understood but it correlates with the rise in the levels of human chorionic gonadotropin , progesterone , and the resulting relaxation of smooth muscle of the stomach.
The cause of placental abruption is not entirely clear. [2] Risk factors include smoking, pre-eclampsia, prior abruption (most important and predictive risk factor), trauma during pregnancy, cocaine use, and previous cesarean section. [2] [1] Diagnosis is based on symptoms and supported by ultrasound. [1] It is classified as a complication of ...
The American Cancer Society recommends starting screening when you turn 45, if you’re at average risk for developing colon cancer; earlier, if you have a family history of the disease or other ...
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
