Sixty-six patients with Duke's B2 or C colon or rectal cancer were randomized for treatment with aspirin (ASA), 600 mg, p.o., twice daily x 2 years or placebo (P). Compliance was checked in both groups by random measurement of blood salicylate levels. Fifty-seven patients are currently evaluable. No difference in disease-free (p = .66) or overall survival(More)
The May-Hegglin anomaly is one of the rare forms of heriditary thrombocytopenia. Since fewer than 100 cases of May-Hegglin anomaly have been described to date, major controversies regarding the adequacy of hemostasis in vivo and abnormalities of platelet function in vitro continue to prevail. This report describes the results of coagulation, platelet(More)
To determine factors involved in peritoneal dialysis-associated peritonitis and catheter loss, all point prevalent peritoneal dialysis patients in Health Care Finance Administration (HCFA) end-stage renal disease (ESRD) Network 9 were followed throughout 1991 for peritonitis events and throughout 1991 to 1992 for catheter survival. Data were collected by(More)
In vitro studies of polymorphs exposed to cellulose and polysulfone membranes showed severe impairment in randommobility with the cellulose membrane. In vivo studies with the two membranes showed that profound leukopenia occurred only when cellulose membrane was used. It is suggested that random mobility may have importance in the regulation of peripheral(More)
In Italian patients with high hemoglobin A(2) beta-thalassemia trait, the synthesis of beta-chains of adult hemoglobin in the peripheral blood is approximately one-half that of alpha-chains. In this study the relative rates of beta- and alpha-chain synthesis were determined in 26 Negro heterozygotes and five homozygotes for beta-thalassemia in six families.(More)
The mechanisms responsible for the transient respiratory alkalosis which follows clinical hemodialysis were evaluated by studying the ventilatory response to carbon dioxide in chronic uremic patients, and in unanesthetized normal and chronic uremic goats. A significant increase in sensitivity to CO2 was found in acidotic uremic patients immediately (within(More)
