Comparative Study
Pharmacologic management of constipation in the critically ill patient.
To compare the effectiveness of common laxatives in producing a bowel movement in patients admitted to a medical intensive care unit (MICU). ⋯ Critically ill patients have a high frequency of constipation, and opioid therapy is a significant risk factor. Routine administration of stimulant or osmotic laxatives should be considered for this patient population.

Case Reports
Amphotericin B-associated hyperbilirubinemia: case report and review of the literature.
A 53-year-old woman with an intraabdominal infection secondary to Candida albicans experienced hyperbilirubinemia after receiving amphotericin B in two different formulations--amphotericin B deoxycholate and amphotericin B lipid complex. Only a few case reports of amphotericin B-induced hyperbilirubinemia have been documented in the literature, each with different patterns of corresponding abnormalities in liver function tests. The unpredictable nature of this adverse effect warrants monitoring of bilirubin levels and liver function at baseline and potentially during therapy with amphotericin B, regardless of formulation, dosage, or duration of therapy.

Millions of patients use nonsteroidal antiinflammatory drugs (NSAIDs) for relief of arthritic pain. Although NSAIDs reduce pain, their use has been linked to gastroduodenal complications. Selective inhibition of the cyclooxygenase (COX)-2 enzyme appeared to offer patients similar pain relief with an improved adverse-effect profile. ⋯ Although selective COX inhibitors provide more gastrointestinal protection than NSAIDs, the unbalanced inhibition of prostaglandins may promote cardiovascular complications. Variability in study designs and inconsistency in results have made the evaluation of NSAID and COX-2 inhibitor safety very difficult, creating confusion among health care practitioners. We examine the pharmacologic and clinical evidence that defines the cardiovascular risk associated with COX inhibition.
