Higher folate needs are present during pregnancy, which may lead to tissular deficiency in the mother and to depleted newborn folate reserves. The aim of this work was to assess the prevalence of folate deficiency and to establish the rates of serum and red cell folate in two groups of mothers and newborn infants, one receiving only iron and the other iron(More)
Hairy cell leukemia (HCL) is a rare chronic B cell lymphoproliferative disorder that affects mostly men. It usually presents with pancytopenia, splenomegaly and bone marrow infiltration, without lymphadenopathy. Diagnosis is based on the presence of mononuclear cells with cytoplasmic projections in a blood smear, the typical bone marrow infiltration pattern(More)
Autologous 51Cr-platelet kinetic studies were performed in splenectomized mongrel dogs. Mean survival time of PRP-platelets was 5.4 +/- 1.5 (SD) days (n = 6). The curves, though slightly curvilinear, showed mostly a linear type of decay, denoting that platelet removal from the circulation is mainly determined by aging of the cells. High-density (HD) and(More)
BACKGROUND The goal of the present work is to describe the development and results of the pediatric epidural analgesia program at the ''Hospital Nacional de Pediatria Prof. Dr. J. P. Garrahan'' in Argentina. METHODS Patients with thoracotomy, abdominal surgery, osteotomy, amputations or severe trauma were included in the program. The program provided(More)
We have treated 28 patients (pts) with malignant hematological diseases with allogeneic bone marrow transplantation (BMT). 18 pts had acute lymphoblastic (ALL) and non lymphoblastic leukemia (ANLL), 5 chronic myeloid leukemia (CML), 2 severe aplastic anemia (SAA), 1 myelodisplasia, 1 Fanconi's anemia and 1 advanced Non Hodgkin's lymphoma. All but three(More)
51Cr-labeled autologous platelets were infused into splenectomized subjects and the specific radioactivities of high-density (HD) and low-density (LD) platelet subpopulations were determined sequentially in postinfusion samples. A rapid decrease in the specific radioactivity of LD cohorts (T1/2 = 2.5 days) was observed, but the specific radioactivity of HD(More)
We report a patient who developed acute renal failure at the first severe hemolytic crisis associated to paroxysmal nocturnal hemoglobinuria. The associated histologic findings on electron microscopy and immunofluorescence are discussed as an insight to possible pathogenic mechanisms.
