Maternal-fetal ABO incompatibility is a common hematological problem affecting the newborn. In general, hemolysis is minimal and the clinical course is relatively benign, rarely causing the escalating levels of hyperbilirubinemia and significant anemia commonly associated with Rh hemolytic disease of the newborn (HDN). The incidence of HDN ranges from one in 150 births to 1:3000 births, dependi...

OBJECTIVE To evaluate the correlations between the components of the Objective Grading System developed by the American Board of Orthodontics (ABO) and smile esthetics. MATERIALS AND METHODS The clinical photographs of 48 orthodontically treated patients were rated by a panel of 25 experienced orthodontists (15 men and 10 women) and 20 parents of orthodontic patients (eight men and 12 women)....

BACKGROUND The prognostic significance of ABO blood type for lymphoma is largely unknown. We evaluated the prognostic role of ABO blood type in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). METHODS We retrospectively analyzed clinical data of 697 patients with newly diagnosed ENKTL from three cancer centers. The prognostic value of ABO blood type was evaluated using Ka...

Many diseases and genetic disorders are associated with ABO and Rh systems of blood antigens. This study was conducted to determine the frequency of ABO and Rhesus (Rh) blood groups in District Rahim Yar Khan, Pakistan so that the results could be used for further application. A total of 9891 subjects including patients and healthy individual were sampled only belonging to District Rahim Yar Kh...

Materials and Methods: This two-year retrospective study of 1800 jaundiced term-neonates studied 355 cases due to ABO incompatibility divided into two groups: with and without hemolytic disease. Relation of laboratory parameters and immunohematological tests to severity of disease were studied. We did not analyze the maternal antibody titer or elusion test, and this was a limitation of the stud...

Background Few studies have documented the blood group antigens in the population of eastern India. Frequencies of some common alleles and haplotypes were unknown. We describe phenotype, allele, and haplotype frequencies in the state of West Bengal, India. Methods We tested 1,528 blood donors at the Medical College Hospital, Kolkata. The common antigens of the ABO, Rhesus, and Kell blood grou...

The generation of ABO hemagglutinins was used as a model to assess the tempo of reconstitution of antibody responses in recipients of elutriated (CCE) and nonelutriated (nonCCE) HLA matched bone marrow allografts. The study included 29 CCE recipients (10 major, 6 minor, and 1 major/minor ABO-mismatched, and 12 ABO-matched) and 40 nonCCE recipients (14 major, 12 minor, 2 major/minor, and 12 matc...

UNLABELLED Acute lymphoblastic leukemia (ALL) constitute a family of genetically heterogeneous lymphoid neoplasms derived from B- and T-lymphoid progenitors. ALL affects both children and adults. Diagnosis is based on morphologic, immunophenotypic, and genetic features that allow differentiation from normal progenitors and other hematopoietic and nonhematopoietic neoplasms. The aim of this stud...

BACKGROUND/AIMS We investigated the impact of the baseline anti-A/B antibody titer on the clinical outcome in ABO-incompatible kidney transplantation (IKT). METHODS We included 183 patients who had undergone KT (40 ABO IKT and 143 ABO-compatible KT). Eight patients with a baseline titer of ≥1:512 were assigned to the high-titer group and 32 patients with a baseline titer of ≤1:256 were assign...

Although some specialty certifying boards began recommending or requiring recertification of their "boarded" specialists as early as 1986, recertification is a relatively new concept for the specialty of orthodontics. In the mid 1990s, the American Board of Orthodontics (ABO) recognized that many other medical and dental specialty boards had already established voluntary or mandatory recertific...
