Pressure ulcers are a frequent complication of bed rest. We examined risk factors for hospital-acquired pressure ulcers, the use of preventive devices, and the impact of case-mix adjustments on between-ward comparisons. ⋯ Pressure ulcers were seen in every 10th hospitalized adult. Patient age and Norton score were the strongest risk factors for pressure ulcers. Use of preventive devices was suboptimal. Adjustment for case mix is essential if pressure ulcer incidence is to be used as an indicator of quality of care.

If asked to define fever, most physicians would offer a thermal definition, such as "fever is a temperature greater than...." In offering their definition, many would ignore the importance of the anatomic site at which temperature measurements are taken, as well as the diurnal oscillations that characterize body temperature. If queried about the history of clinical thermometry, few physicians could identify the source or explain the pertinacity of the belief that 98.6 degrees F (37.0 degrees C) has special meaning vis-à-vis normal body temperature. ⋯ A distinct minority would appreciate the obvious paradoxes inherent in an enlarging body of data concerned with the question of fever's adaptive value. The present review considers many of these issues in the light of current data.

Superwarfarin sodium exposure or poisoning is a growing public health problem. There were 5133 reported cases of superwarfarin exposure and poisoning in 1988 and 13 423 cases in 1995. Cases may be associated with accidental exposure, suicide attempts, or Munchausen syndrome, and may be difficult to diagnose. ⋯ Superwarfarin exposure or poisoning is a growing public health problem that should be part of the differential diagnosis of patients who present with a coagulopathy consistent with vitamin K deficiency in the absence of coumadin therapy, liver disease, or the use of an inhibitor, and whose conditions do not resolve with large doses of parenteral vitamin K1 therapy.

To evaluate the 3 alcohol consumption questions from the Alcohol Use Disorders Identification Test (AUDIT-C) as a brief screening test for heavy drinking and/or active alcohol abuse or dependence. ⋯ Three questions about alcohol consumption (AUDIT-C) appear to be a practical, valid primary care screening test for heavy drinking and/or active alcohol abuse or dependence.
