The behavioral effects of iron deficiency and its treatment were evaluated in a double-blind randomized controlled community-based study of 191 Costa Rican infants, 12 to 23 months of age, with various degrees of iron deficiency. The Bayley Scales of Infant Development were administered before and both 1 week and 3 months after IM or oral administration of(More)
BACKGROUND Disseminated histoplasmosis usually occurs in immunocompromised patients who reside in Histoplasma capsulatum-endemic regions. It has also been described in immunocompetent infants after exposure to a large inoculum of the pathogen resulting in case fatality rates of 40 to 50%. METHODS From 1983 through 1996 all infants with documented(More)
We describe a 15-month-old eutrophic immunocompetent male who presented with fever, hepatosplenomegaly, pancytopenia, and hypergammaglobulinemia. Leishmania amastigotes were identified in spleen and bone marrow specimens. In addition, tissue culture, animal inoculation, and isoenzyme analysis identified the parasite as Leishmania donovani infantum or(More)
Antithrombin activities in 30 severely malnourished children and 40 normal children were estimated in clotting tests by thrombin neutralisation as anti-Xa and by a heparin antithrombin assay; and by immunodiffusion as alpha 2-globulin and alpha 1-antitrypsin. The patients' mean alpha 2-globulin was severely depressed, and there were less marked depletions(More)
Antithrombin III (AT III) and heparin antithrombin assay were estimated in 30 severely malnourished children and 40 normal children. The AT III was found significatively depressed and the heparin antithrombin assay showed a flat curve in the patients, which reflects a prethrombotic pattern in this group of children. Those findings agree with the high(More)
