In 1996, nearly 60% of U.S. AIDS cases among Latinas were attributed to unprotected sex with men. Economic disadvantage, language barriers, and strong cultural gender norms regarding sex exacerbate the risk for HIV infection among Latina immigrant women. Through a collaboration among scientists and providers, this study was designed to evaluate the impact(More)
It has been experimentally shown that endotoxin induces a significant increase in the blood levels of a plasminogen activator inhibitor (PAI). We evaluated the effect of different doses of heparin (5 to 20 IU kg-1 h-1), antithrombin III (10 to 40 U kg-1 h-1 and 240 U/kg as bolus) and of a combination of the two on: 1) the elevation of PAI activity, 2)(More)
The lower mortality and morbidity rates of the gastric partitioning operations seem to be the primary reason for their increasing popularity among surgeons everywhere. Two hundred patients in our series underwent gastroplasty for morbid obesity. A measured 60-ml proximal gastric pouch is formed as the TA-90 is doubly applied across the upper stomach, just(More)

Disseminated intravascular coagulation (DIC) was induced in 84 rabbits by intravenous infusion of 20 micrograms/kg/h of endotoxin during 6 hours. The following treatments were administered simultaneously with endotoxin: heparin, 5, 10 and 20 UI/kg/h, antithrombin III (AT III), 10, 20 and 40 U/kg/h or as a 240 U/kg bolus dose, and heparin (10 UI/kg/h) plus(More)
The authors report a case of seronegative polyarthritis resistant to the anti-inflammatory therapy in a 16-year-old male with intermittent diarrhea. A stool examination showed the presence of cysts of Giardia lamblia and an immunological study detected a partial serum IgA deficiency, including its secretory fraction. Based on clinical, analytical and(More)
A 10-year-old female with a complete selective IgA deficiency and recurrent autoimmune disease (chronic active hepatitis, focal glomerulonephritis, hemolytic anemia and thrombopenic purpura) is presented. Both serum IgA and saliva secretory IgA were below the detection limit. The small bowel biopsy using a peroxidase-antiperoxidase technique showed absence(More)
