In examining the artificial intelligence literature, one may find that there have been many attempts to build decision-support systems that provide the user with a conclusion and an explanation for that conclusion. For example, in the medical domain, systems such as MYCIN (Shortliffe, 1976) and MENINGE (François et al., 1993) have been developed to aid the(More)
In recent years, there has been increased discussion about the potential of expert systems to support medical decision-making tasks, including applications in clinical laboratory settings. This study provides data regarding the cognitive errors that technologists make on an important problem-solving task: the identification of antibodies in a patient's(More)
Two patients who had hemolysis after receiving large doses of intravenous immune serum globulin are reported. Both patients had positive direct antiglobulin tests due to alloantibodies contained in the immune serum globulin. Markedly increased red cell transfusion requirements and elevated serum bilirubin levels provided evidence of hemolysis.
A patient with aplastic anemia received an ABO incompatible bone marrow transplant (BMT) from an HLA identical sibling. Weekly HLA antibody screens were performed as part of the BMT protocol. At the time of transplant, a hemolytic anti-Le(a) was detected in the Le (a-b-) donor. The Le (a-b+) recipient had no red cell or LCT antibody. A hemolytic anti-Le(a)(More)
Fetomaternal hemorrhage can result from different types of trauma and may be followed by fetal anemia, fetal death, or isoimmunization. We prospectively studied the frequency and volume of fetomaternal hemorrhage, fetal well-being, abruptio placentae, and fetal outcome in 32 pregnant patients suffering recent trauma. Fetomaternal hemorrhage occurred in nine(More)
A premature male infant with hyaline membrane disease received a 34 ml transfusion of packed erythrocytes from a CPDA1 blood unit on day 2 with no adverse consequences. On day 34 he was given a transfusion, and the platelet count decreased. Intravenous immune globulin therapy was initiated and the platelet count steadily increased. Human leukocyte (HLA)(More)
Anti-E is rarely acknowledged as a cause of severe hemolytic disease of the newborn. A patient presented with a low titer (32) that increased following repeated amniocentesis, used to evaluate the fetal condition. The infant developed severe disease requiring multiple exchange transfusions but did well and was discharged in good condition.
Previous research during the development of Antibody IDentification Assistant (AIDA) revealed that many medical technology students and other laboratory personnel have serious difficulties in determining the specificity of blood group alloantibodies, especially weak or multiple antibodies. Based on these previous results, AIDA was modified to provide a(More)
