The Labor Room It is accepted that the umbilical cord should be clamped early in known and suspected cases of erythroblastosis. When isoimmunization is not a factor, some advocate late clamping to effect a physiologic transfusion. Others say this produces excessive blood volume, which may be a causative factor in the respiratory-distress syndrome. Studies by umbilical-vein catheterization thus ...

OBJECTIVE To evaluate whether the use of intravenous immunoglobulin in newborn infants with isoimmune hemolytic jaundice due to Rh and ABO incompatibility is an effective treatment in reducing the need for exchange transfusion. METHODS This study included all direct Coombs' test positive Rh and ABO isoimmunized babies, who admitted in the Neonatal Intensive Care Unit of Ghaem Hospital of Mash...

Introduction: Jaundice is an important problem during neonatal period. When total serum bilirubin (TSB) level exceeds a critical limit, it crosses the blood brain barrier and results into bilirubin encephalopathy. The main aim of therapy for neonatal hyperbilirubinemia is prevention of bilirubin encephalopathy by phototherapy and/or exchange transfusion. The aims of this study were to evaluate ...

BACKGROUND AND OBJECTIVES To determine whether there is a delay or reversal in switch mechanisms from embryonic (e and z) to fetal (g) hemoglobins accompanying the erythroblastosis of anemic fetuses and whether an increased erythroblast count in fetal blood is associated with an increase in feto-maternal cell trafficking. DESIGN AND METHODS Fetal and maternal blood samples were obtained from ...

OBJECTIVE To investigate the clinical characteristics of fetal hydrops and to find the antenatal ultrasound findings predictive of adverse perinatal outcome. METHODS This is a retrospective study of 42 women with fetal hydrops who delivered in a tertiary-referral center from 2005 to 2013. Fetal hydrops was defined as the presence of fluid collection in ≥2 body cavities: ascites, pleural effus...

Background and aim Rh isoimmunization still contributes to the neonatal morbidity and mortality due to non-immunization, under-immunization, and in rare cases, false Rh typing. The main objective of this study was to determine the prevalence of Rh incompatibility, mothers' knowledge about Rh incompatibility, mothers' knowledge about anti-D immunoglobulin and to show the pregnancy outcome of Rh ...

By RICHARD H. ASTER P LATELET-RICH PLASMA and platelet concentrates are frequently effective in the treatment of hemorrhage secondary to thrombocytopenia.16 The recovery of transfused platelets in the recipients is often low, however, the average ranging from 20-33 per cent in several series.3’5”1 Previous work in this laboratory has shown that a citrate anticoagulant which buffers platelet-ric...

CONTEXT/OBJECTIVE Hyperinsulinism with islet cell hyperplasia is a frequent complication, of unknown cause, in hemolytic disease of the newborn, occurring in Rh(D)-positive infants of Rh-isoimmunized Rh(D)-negative mothers, but not in infants with other hemolytic disorders. We investigated the possibility that trans-placentally acquired anti-D Ig is the cause of both conditions. DESIGN Monola...

I SOIMMUNE leukocyte antibodies have been reported frequently since the initial communication of Dausset and Nenna’ in 1952. A large literature has accumulated and was recently fully reviewed by Walford,2 who listed over 500 reports. Most of these have been concerned chiefly with establishing the presence of such antibodies, the mechanisms by which they cause pathological effects being still co...

BACKGROUND Rh isoimmunization and hemolytic disease of the newborn still occur despite the availability of Rh immunoglobulin. For the prenatal investigation of sensitized RhD-negative pregnant women, determination of the zygosity of the RhD-positive father has important implications. The currently available molecular methods for RhD zygosity assessment, in general, are technically demanding and...
