hydrops fetalis

Kernicterus, Rh incompatibility, Rh-induced hemolytic disease of newborn Obstetrics An accumulation of fluid in neonates, resulting in a 'puffy', plethoric or hydropic appearance that may be due to various etiologies Clinical Ascites, edema, ↓ protein or chronic intrauterine anemia, hepatosplenomegaly, cardiomegaly, extramedullary hematopoiesis, jaundice, pallor COD Heart failure. See Hemolytic disease of the newborn.
Hydrops Fetalis, causes
Immune Mother produces IgG antibodies against infant antigen(s), often an RBC antigen, most commonly, anti-RhD, which then passes into the fetal circulation, causing hemolysis
Non-immune Hydrops may result from various etiologies including
•  Fetal origin, eg congenital heart disease (premature foramen ovale closure, large AV septal defect), hematologic (erythroblastosis fetalis, α-thalassemia due to hemoglobin Barts, chronic fetomaternal or twin-twin transfusion), infection (CMV, herpesvirus, rubella, sepsis, toxoplasma), pulmonary (cystic adenomatoid malformation, diaphragmatic hernia, with pulmonary hypoplasia, lymphangiectasia), renal (vein thrombosis, congenital nephrosis) and teratomas, skeletal malformations (achondroplasia, osteogenesis imperfecta, fetal neuroblastomatosis, storage disease, meconium peritonitis, idiopathic)
•  Placental Chorangioma, umbilical or chorionic vein thrombosis
 Maternal DM, toxemia

This study aims to determine the pathological changes of placentas from mothers with preeclampsia or eclampsia and correlate the findings with the clinical severity of the disease, placental weight, and birth weights of the newborn babies.
We performed a prospective study to compare the placental diffusion difference in 63 patients (gestational week, 28-34 weeks), including 50 IUGR patients with worsening Doppler US findings (mean gestational week, 30 weeks 3 days [+ or -]16.2 days) and patients with normal Doppler US findings (n=13) (mean gestational week, 29 weeks 4 days[+ or -]12.3 days) by using DWI (b value, 0-1000 s/[mm.sup.2]).
Distal villous hypoplasia and increased syncytial knots (aggregation of syncytiotrophoblastic nuclei on the periphery of tertiary placental villi, forming a huge multinucleated protrusion from the villous surface) can also be visualized8.
Buganim and colleagues found a new combination of five genes that, when inserted into skin cells, reprogram the cells into each of three early embryonic cell types: iPS cells that create fetuses, placental stem cells, and stem cells that develop into other extra-embryonic tissues, such as the umbilical cord.
During that relative brief follow-up period, the adjusted risk of cardiovascular disease was increased by 19% in those with a maternal placental syndrome, compared with those without.
The plaintiff submitted that the lab staff told her that a placental tissue sample had a limited life of few hours and it had expired due to late testing by the lab analysts.
Therefore, the mature placental barrier will comprise the following components: syncytiotrophoblast, cytotrophoblast, extraembryonic mesoderm, and the endothelial lining of the chorionic vessels (Sadler; Huppertz; Prieto Gomez et al., 2011; Roa et al.; Carlson).
During placental development, angiogenesis and trophoblast invasion into maternal decidua necessitate remodeling and breakdown of extracellular proteolytic enzymes.
