To measure the extent of cardiovascular morbidity associated with nonadherence to 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) therapy. ⋯ A detectable excess of cardiovascular morbidity appears to be associated with nonadherence to statin therapy. Our analysis suggests that many occurrences of myocardial infarction could be prevented with improvements in adherence. Larger studies are necessary to determine the association between adherence and other cardiovascular end points.

An 81-year-old woman with ischemic bowel underwent laparotomy with small-bowel resection and developed septic shock. She required broadspectrum antibiotics, norepinephrine, and mechanical ventilation. The patient received drotrecogin alfa (activated) 24 microg/kg/hour for a total of 67.5 hours. ⋯ In postmarketing reports, clinically significant bleeding occurred more frequently than was noted in a large, randomized, multicenter trial. Patients receiving drotrecogin alfa (activated) should be closely monitored for prolongation of coagulation parameters. Temporary discontinuation of the drug should be considered when international normalized ratio is greater than 3.0, platelet count is less than 15x10(3)/mm3, and aPTT is greater than 100 seconds.

Fortunately, the occurrence of acute myeloid leukemia (AML) during pregnancy is rare. We report a case of successful fetal outcome with standard induction and consolidation treatment in the second and third trimesters, respectively. A 37-year-old woman in her second trimester (21 wks) of pregnancy was found to have acute myeloid leukemia. ⋯ Approximately 4 weeks after delivery, the mother underwent autologous peripheral stem cell transplantation. Unfortunately, 100 days after transplantation, she had a relapse of AML. After a brief remission from a second induction, the patient died.

Hyperglycemia is a common problem encountered in hospitalized patients, especially in critically ill patients and those with diabetes mellitus. Uncontrolled hyperglycemia may be associated with complications such as fluid and electrolyte disturbances and increased infection risk. Studies have demonstrated impairment of host defenses, including decreased polymorphonuclear leukocyte mobilization, chemotaxis, and phagocytic activity related to hyperglycemia. ⋯ Intensive insulin therapy minimizes derangements in normal host defense mechanisms and modulates release of inflammatory mediators. The principal benefit of intensive insulin therapy is a decrease in infection-related complications and mortality. Further research will define which patient populations will benefit most from intensive insulin therapy and firmly establish the blood glucose concentration at which benefits will be realized.

To determine whether metformin therapy, compared with sulfonylurea therapy, is associated with a delayed onset of secondary failure in patients with type 2 diabetes mellitus. ⋯ Compared with sulfonylurea therapy, metformin therapy appears to be associated with a delay in the onset of secondary failure.
