BACKGROUND: Neonatal blueberry muffin lesions are rare cutaneous eruptions, presenting as transient, non-blanching, red-violaceous papules, mostly localized in the trunk, head and neck, attributable to a marked dermal hematopoietic activity. Congenital infections of the TORCH complex (toxoplasmosis, other, rubella, cytomegalovirus and herpes) and hematological disorders have been classically associated with this neonatal dermatological manifestation. We report for the first time an unusual presentation of blueberry muffin lesions in a neonate born from a mother affected by severe anemia during pregnancy...

CONTEXT: -Chorangiosis has been regarded as a result of low-grade placental hypoxia associated with pregnancy risk factors and abnormal outcomes. It is unknown whether these are a consequence of chorangiosis itself or of associated other placental pathology. OBJECTIVE: -To prove that chorangiosis itself does not portend an increased risk for pregnancy unless associated with other placental pathology. DESIGN: -This retrospective statistical study analyzes 1231 consecutive placentas with diffuse or focal hypervascularity of chorionic villi: 328 with preuterine pattern of chronic hypoxic placental injury (group 1), 297 with uterine type of chronic hypoxic placental injury (group 2), and 606 cases with chorangiosis (group 3) not fulfilling the inclusion criteria for groups 1 or 2...

Anti-G is commonly present with anti-D and/or anti-C and can confuse serological investigations. in general, anti-G is not considered a likely cause of severe hemolytic disease of the fetus and newborn (HDFN), but it is important to differentiate it from anti-D in women who should be administered anti-D immunoglobulin prophylaxis. We report one woman with three pregnancies severely affected by anti-C+G requiring intrauterine treatment and a review of the literature. In our case, the identification of the correct antibody was delayed because the differentiation of anti-C+G and anti-D+C was not considered important during pregnancy since the father was D-...

A blood requisition for double-volume exchange transfusion was received for a 2-day-old male child born to a 29-year-old multiparous female (P2002) referred to our institute having neonatal jaundice with encephalopathy; no maternal sample was received. the neonatal blood sample was typed as group A, D-, and the direct antiglobulin test (DAT) was strongly positive (4+) using the gel method. Mono-specific DAT showed the presence of IgG antibodies on neonatal red blood cells (RBCs). Acid elution and gentle heat elution (at 56°C) confirmed the presence of anti-D on neonatal RBCs...

BACKGROUND: Anti-C(w) are rarely found as a source for severe fetal and neonatal hemolytic diseases. We report a case with serial intrauterine transfusions complicated by pancytopenia and cholestasis in the neonatal period. CASE REPORT: A 37-year-old woman revealed anti-C(w) with a titer of 512 in her fourth pregnancy. The fetus developed fetal anemia and a severe hydrops requiring three intrauterine red blood cell (RBC) transfusions. After birth at 33 + 0 weeks the newborn presented only transfused RBCs and suffered from anemia, thrombocytopenia, leukopenia, and a cholestatic liver disease...

ABO hemolytic disease of the newborn occurs almost exclusively in infants of blood group A and B who are born to group O mothers. Positive Direct Antiglobulin Test (DAT) can identify those infants who are at risk of developing the ABO hemolytic disease. Earlier studies have suggested that BO incompatibility is associated with a positive DAT in black infants. In this study we sought to determine whether ABO incompatibility type could be associated with a higher rate of DAT positivity or clinical hemolytic disease...

The Kell and Kx blood group systems are expressed as covalently linked molecules on red blood cells (RBCs). The Kell blood group system is very polymorphic, with 35 antigens assigned to the system. The expression of Kell glycoprotein on RBCs is not critical to the erythrocyte function. However, the expression of KX is critical to normal morphology, and null mutations are associated with the McLeod neuroacanthocytosis syndrome. The immunogenicity of the K anigen is second only to the D anigen, and alloantibodies to Kell anigens can cause transfusion reactions and hemolytic disease of the fetus and newborn...

BACKGROUND: Small for gestational age and birth asphyxia are associated with neonatal transient hyperinsulinism (THI). Some newborns with THI showed marked erythroblastosis on admission to our neonatal intensive care unit. OBJECTIVE: This study was designed to test our hypothesis that fetal erythroblastosis may be a risk factor for developing THI. METHODS: The records of all babies admitted to our neonatal intensive care unit within 24 h of birth between January 2010 and May 2014, and who were born after 34 weeks of gestation, were retrospectively reviewed...

BACKGROUND: Anti-KEL1(K) is a major cause of hemolytic disease of the fetus and newborn. We utilized data from prenatal testing of patients in Western Canada to determine the frequency of anti-K. In Manitoba, we evaluated the frequency of transfusion as the likely cause for alloimmunization. We reviewed international practices to prevent alloimmunization. STUDY DESIGN AND METHODS: Prenatal patients undergo antibody screening using an automated testing platform and uniform testing algorithm...

Hemolytic disease of the newborn (HDN) arising from MNSs incompatibility is rare, with few reports of prolonged anemia and reticulocytopenia following HDN. We report the younger of 2 male siblings, both of whom had anti-M-induced HDN and anemia persisting for over a month. Peripheral reticulocytes remained inappropriately low for the degree of anemia, and they needed multiple red cell transfusions. Viral infections were ruled out. Corticosteroids were given for suspected pure red cell aplasia. Anemia and reticulocytopenia subsequently improved...

Haemolytic Disease of the Fetus and Newborn (HDFN) is caused by maternal alloimmunization against red blood cell antigens. In severe cases, HDFN may lead to fetal anaemia with a risk for fetal death and to severe forms of neonatal hyperbilirubinaemia with a risk for kernicterus. Most severe cases are caused by anti-D, despite the introduction of antental and postnatal anti-D immunoglobulin prophylaxis. In general, red blood cell antibody screening programmes are aimed to detect maternal alloimmunization early in pregnancy to facilitate the identification of high-risk cases to timely start antenatal and postnatal treatment...

Numerous diseases are known to cause microstructural alteration of dental tissues structure. One type in particular is associated with neonatal jaundice and circulation of bilirubin in blood at high concentration due to increased hemolysis in conditions such as erythroblastosis fetalis, septicemia, biliary atresia, and other causes of hyperbilirubinemia. In those conditions, the products of the catabolism of hemoglobin end up deposited in various tissues, including teeth, where they can present clinically as visibly stained brown/green teeth...

BACKGROUND: Hemolytic disease of the fetus and newborn, classically caused by maternal-fetal incompatibility of the Rh blood group D antigen, can be prevented by RhIG prophylaxis. While prophylactic practices for pregnant women with serologic weak D phenotypes vary widely, RHD genotyping could provide clear guidance for management. This analysis evaluated the financial implications of using RHD genotyping to guide RhIG prophylaxis among pregnant females. STUDY DESIGN AND METHODS: A Markov-based model was constructed to evaluate the costs of RHD genotyping for pregnant females with serologic weak D phenotypes to inform RhIG prophylaxis...

BACKGROUND: Severe hemolytic anemia of the fetus, caused by maternal red blood cell (RBC) alloantibodies, is treated with intrauterine transfusion (IUT) of RBCs. Because IUT is associated with additional antibody formation, RBCs with the closest match between donor and mother are preferred. Because one fetus needs a median of three IUTs, finding such RBCs is complicated. Collection of repeated low-volume donations from one selected donor during the entire IUT treatment period would reduce donor exposure and possibly IUT-associated alloimmunization...

OBJECTIVE: The objective of the study was to determine whether women with combinations of red blood cell antibodies are more likely to develop significant hemolytic disease of the fetus and newborn than those with single antibodies. STUDY DESIGN: A retrospective exposure cohort study was conducted of pregnant women with red blood cell antibodies. The development of significant hemolytic disease of the fetus and newborn was then compared between patients with single antibodies and those with multiple antibodies...

BACKGROUND: The direct antiglobulin test (DAT) is the cornerstone of the diagnosis of hemolytic disease of the newborn (HDN). The aim of this study was to review the incidence and causes of positive DAT in cord blood in relation to development of HDN. METHODS: We retrospectively reviewed all results of DAT, which is routinely performed in cord blood samples, along with the laboratory and infants' medical records. RESULTS: DAT was positive in 70/2695 (2...
