Pharmacotherapy

To determine whether use of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) is associated with a reduced rate of severe sepsis, and to further characterize the effect of statins on the frequency of organ dysfunction in patients with severe sepsis. ⋯ Statins appear to prevent sepsis from becoming severe, most notably through prevention of sepsis-induced hypotension. This potential role for statins in the prevention and treatment of severe sepsis should be further evaluated in a randomized controlled trial.

Review Case Reports
Povidone-iodine-induced burn: case report and review of the literature.
Burns are a rare but potentially serious complication of povidone-iodine use. This rare adverse drug reaction developed in a 38-year-old woman who underwent laparoscopic right ovarian cystectomy and endometrial ablation as a day procedure involving application of the topical antiseptic 10% povidone-iodine solution. Two days later, the patient was admitted to the hospital with burning, pain, itching, marked redness, and blistering extending from her midback to buttocks. ⋯ The burn is usually seen immediately after the procedure or on the next day, and typically heals with minimum scarring within 3-4 weeks with conservative treatment. The commonly postulated mechanism is a chemical burn due to irritation coupled with maceration, friction, and pressure. Given the widespread use of povidone-iodine and the potential for development of infection after a burn, clinicians need to be aware of this possible povidone-iodine-associated adverse drug reaction, and of preventive measures.

Case Reports
Erythema multiforme after meningitis vaccine: patient safety concerns with repeat immunization.
A 20-year-old college student developed an immunologic hypersensitivity reaction, erythema multiforme minor, 1-2 weeks after receiving a meningococcal conjugate vaccine. He had no history of erythema multiforme, nor had he received any other vaccine or drug therapy. The temporal relationship between the development of erythema multiforme and the vaccination suggests that the meningitis vaccine probably was the causal agent. The occurrence of this distinct cutaneous reaction, with the potential for a serious complication such as erythema multiforme major or Stevens-Johnson syndrome on rechallenge, should serve as a warning against repeated booster vaccinations in patients who develop reactions such as this one.

Multicenter Study Comparative Study Clinical Trial
Erythropoietic response to two epoetin alfa regimens in critically ill patients: a pilot study.
To compare the erythropoietic responses and tolerability of two recombinant human erythropoietin (EPO) regimens. ⋯ Although the study had limitations, it suggested that EPO 40,000 U twice/week did not increase or sustain stimulation of the erythropoietic response compared with EPO 40,000 U/week in critically ill patients.

Antiplatelet therapy is commonly administered for primary and secondary prevention of stroke, recurrent angina, myocardial infarction, and death in patients with cardiovascular disorders. It also is associated with an increased risk of bleeding. ⋯ This information is integrated with results from pharmacologic studies and clinical trials. Determining the net effect in patients undergoing coronary artery bypass graft surgery requires knowledge about the pharmacokinetics, pharmacodynamics, and clinical efficacy of each drug, and an estimation of the absolute thrombotic versus hemorrhagic risk for each patient.
