13. Estimation of the residual risk for the transmission of HIV in blood donors from the mountain region of Santa Catarina
The HIV, in hemotheraphy, may be transmitted by erythrocyte, platelets, crioprecipitated, frozen fresh plasma and possibly, by other blood components. Appropriate legislations for this new reality were elaborated normatizing the hemotheraphy practices in Brazil, creating a set of procedures and actions aiming at guaranteeing the quality of the blood, during,

14. Blood transfusion and iatrogenic risks in Mexico city: anti-Trypanosoma cruzi seroprevalence in 43,048 blood donors, evaluation of parasitemia, and electrocardiogram findings in seropositive
Iatrogenous transmission of Trypanosoma cruziby blood transfusion was suggested as a potential risk by Pellegrino (1949). Seropositive blood donors in Mexico were first reported in 1978, however, limited information is available due to small sampling, the use of heterogeneous serologic assays, and geographically limited studies. A wide survey carried out in

15. "Prática de medicina baseada em evidências em um centro de tratamento intensivo pediátrico" / The practice of evidence-based medicine in a pediatric intensive care unit
Objetivos: Estimar a concordância entre as práticas e as evidências disponíveis em uma unidade de terapia intensiva pediátrica. Métodos: Estudo retrospectivo de todos os pacientes internados durante 2001. As práticas foram classificadas em adequadas ou não-adequadas de acordo com recomendações. Esperava-se para as práticas recomendadas 90% de conc

16. In vivo binding of circulating immune complexes by C3b receptors (CR1) of transfused erythrocytes.
The effects of packed erythrocyte transfusion with high CR1 activity on circulating immune complex concentrations were studied in 14 transfusion experiments involving 12 patients with immune complex related diseases. Before erythrocyte transfusion circulating immune complex concentrations ranged from 8 to 128 micrograms/ml. After transfusion (2-3 units) immu

17. Transfusion-associated bacterial sepsis.
The incidence of sepsis caused by transfusion of bacterially contaminated blood components is similar to or less than that of transfusion-transmitted hepatitis C virus infection, yet significantly exceeds those currently estimated for transfusion-associated human immunodeficiency and hepatitis B viruses. Outcomes are serious and may be fatal. In addition, tr

18. Survival of Human Sickle-Cell Erythrocytes in Heterologous Species: Response to Variations in Oxygen Tension
Survival characteristics, after transfusion, of erythrocytes from patients with homozygous sickle-cell disease were studied in rats. The study was made possible by previous injection of the animals with ethyl plamitate, which depressed reticuloendothelial system function, and with a factor in cobra venom that inactivated complement. This treatment prevented

19. Molecular relatedness of Staphylococcus epidermidis isolates obtained during a platelet transfusion-associated episode of sepsis.
Staphylococcus epidermidis was isolated from the blood of a 25-year-old pregnant woman following the administration of eight units of platelets. She had developed chills and a fever of 41.4 degrees C soon after the transfusions were completed. S. epidermidis was also obtained from all eight platelet units, as well as from the packed-erythrocyte unit associat

20. Yersinia enterocolitica in donor blood: a case report and review.
Routine sterility control of a unit of leukocyte-depleted erythrocyte concentrate yielded growth of Yersinia enterocolitica serotype O:3. Plasma of the donor showed a high titer of agglutinins against the homologous organism. Although the donor was apparently well at the time of donation, he had a history of protracted terminal ileitis treated by surgery. Th

21. Modulation of erythropoietin formation by changes in blood volume in conscious dogs.
1. A possible influence of the filling of the circulatory system on the plasma concentration of erythropoietin, which is the major regulator of erythrocyte formation, was investigated in conscious dogs. 2. Over an experimental period of 5 h, the animals were subjected to either haemorrhage (hypovolaemia), blood volume expansion (hypervolaemia), or exchange t

22. Successful hematopoietic reconstitution with transplantation of erythrocyte-depleted allogeneic human umbilical cord blood cells in a child with leukemia.
Cord blood, a potent source of hematopoietic stem cells, has been shown to successfully reconstitute hematopoiesis following allogeneic transplantation in a variety of disorders. A major drawback of cord blood has been the risk of transfusion reactions in ABO blood group incompatibility and drastic reduction in the stem cell pool if the cord blood is manipul

23. Hypothesis: disseminated intravascular inflammation as the inflammatory counterpart to disseminated intravascular coagulation.
We have identified a leukocyte activation syndrome that is occasionally associated with the transfusion of intraoperatively recovered erythrocytes. This syndrome appears to result from intravascular damage caused by leukocytes activated during the erythrocyte salvage process. We hypothesize that this syndrome is part of a larger disease grouping: disseminate

24. Enzyme replacement therapy in Gaucher's disease: preliminary clinical trial of a new enzyme preparation.
A patient with far-advanced adult type Gaucher's disease was treated with solubilized, highly purified placental glucocerebrosidase administered after entrapment in human erythrocytes or by direct intravenous injection. In some instances the enzyme-containing erythrocytes were coated with gamma globulin. No toxic side effects were observed after enzyme infus
