The implementation of a program on routine antenatal anti-D prophylaxis (RAADP) in the developed world has led to a significant decline in the residual numbers of Rhesus negative women becoming sensitized. However, a significant number of Rhesus D negative women in SSA are not fortunate because of lack of access to prophylactic immunoglobulin D and thus they continue to be affected. The managem...

Nearly all pregnancies include an insignificant hemorrhage of fetal blood into the maternal circulation. In some cases, the hemorrhage is large enough to compromise the fetus, resulting in fetal demise, stillbirth, or delivery of a severely anemic infant. Unfortunately, the symptoms of a significant fetal-maternal hemorrhage can be subtle, nonspecific, and difficult to identify at the time of t...

The transfer of fetal cells into mothers during pregnancy and their organ specific integration is a well recognized phenomenon in placental vertebrates. Recently, it has been reported that some fetal cells found in the mothers have progenitor cell-like features such as multilineage differentiation potential and as a consequence they were termed pregnancy associated progenitor cells (PAPC). The ...

BACKGROUND Fetomaternal hemorrhage (FMH) is a poorly understood condition in which the placenta allows transmission of fetal whole blood to the mother. FMH can cause fetal anemia resulting in critical illness, death or lifelong disability. Ascertainment of the incidence of FMH is limited by reliance on retrospective studies that are dependent on a diagnosis of FMH being made at the time of pati...

Fetomaternal alloimmune thrombocytopenia (FMAIT) is the most common cause of severe neonatal thrombocytopenia in otherwise well, term infants. First pregnancies are often severely affected. This descriptive, population-based national study was undertaken in order to inform the case for antenatal screening. Cases were identified using three sources and capture-recapture techniques used to genera...

BACKGROUND Flow cytometric methods (FCMs) are the contemporary standard for fetal red blood cell (RBC) quantitation and fetomaternal hemorrhage (FMH) detection. FCM provides greater sensitivity and repeatability relative to manual microscopic Kleihauer-Betke methods. FCM assays are not totally objective, employing subjective manual gating of fetal RBCs with measureable interobserver imprecision...

External cephalic version (ECV) at term is a safe procedure and reduces the incidence of cesarean sections for breech presentation. One of the known complications, however, is an ECV-related disruption of the placental barrier and a subsequent transfusion of fetal blood into maternal circulation. While the incidence of ECV-related fetomaternal hemorrhage (FMH) has been determined recently in a ...

Rhesus (Rh) isoimmunization presenting as severe neonatal hemolytic disease is rare in RhD negative primigravidas of Chinese ethnicity. We report the case of a 32-year-old pregnant Taiwanese woman, RhD negative, who gave birth vaginally to two RhD-positive full-term fetuses 6 years apart. Antenatal follow-up was uneventful and there was no obvious fetal-maternal hemorrhage except at the perform...

OBJECTIVE To identify risk factors for Rhesus D (RhD) immunisation in pregnancy, despite adequate antenatal and postnatal anti-D prophylaxis in the previous pregnancy. To generate evidence for improved primary prevention by extra administration of anti-D Ig in the presence of a risk factor. DESIGN Case-control study. SETTING Nation-wide evaluation of the Dutch antenatal anti-D-prophylaxis p...
