Extended matched intrauterine transfusions reduce maternal Duffy, Kidd, and S antibody formation.

Background: Severe alloimmune hemolytic disease of the fetus is treated with intrauterine transfusions (IUTs). Despite C, c, E, e, and K matching between mother and donor, IUT results in new antibodies in approximately 25% of women. Newly formed Fy(a), Fy(b), Jk(a), Jk(b), and S antibodies are in 83% presumably induced by the IUT donor.

When somebody loses weight, where does the fat go?

Ruben Meerman and Andrew Brown explain why the answer might not be what you expect.

Term perinatal mortality and morbidity in monochorionic and dichorionic twin pregnancies: a retrospective study.

Aim: Perinatal mortality and morbidity in monochorionic (MC) twins appears to be increasing compared to dichorionic (DC) twins. The aim of our study was to determine the difference in perinatal mortality and morbidity in MC and DC twins born after 37 weeks' gestation.

Design: A retrospective, cross-sectional study of medical records.

Implementation of routine screening for Kell antibodies: does it improve perinatal survival?

Background: In 1998 a national program for first-trimester screening for red cell (RBC) antibodies in all pregnant women was implemented. The aim of our study was to assess the impact on perinatal mortality caused by Kell alloimmunization

Study Design And Methods: Prospectively collected data on all pregnant women referred to our center from 1988 until 2005 for intrauterine transfusion (IUT) for fetal anemia due to Kell alloantibodies were analyzed. The cohort was divided into two groups, those treated before 1998 and those treated after 1998.
