Patients with heart failure have a wide spectrum of mortality risks. To maximize the benefit of available pharmacotherapies, patients with high mortality risk should receive high rates of drug therapy. ⋯ Patients with heart failure at greatest risk of death are least likely to receive ACE inhibitors, ACE inhibitors or ARBs, and beta-adrenoreceptor antagonists. Understanding the reasons underlying this mismatch may facilitate improvements in care and outcomes for patients with heart failure.

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic form of renal phosphate wasting that results in severe hypophosphatemia, a defect in vitamin D metabolism, and osteomalacia. This debilitating disorder is illustrated by the clinical presentation of a 55-year-old woman with progressive fatigue, weakness, and muscle and bone pain with fractures. After a protracted clinical course and extensive laboratory evaluation, tumor-induced osteomalacia was identified as the basis of her clinical presentation. In this article, the distinctive clinical characteristics of this syndrome, the advances in diagnosis of TIO, and new insights into the pathophysiology of this disorder are discussed.

The Accreditation Council for Graduate Medical Education implemented mandatory work hour limitations in July 2003, partly out of concern for residents' well-being in the setting of sleep deprivation. These limitations are likely to also have an impact on other aspects of the lives of residents. ⋯ Past interventions suggest that residents' quality of life may improve with work hour limitations, but interpretation of the outcomes of these studies is hampered by suboptimal study design and the use of nonvalidated instruments. The long-term impact of reducing resident work hours on education remains unknown. Current and future interventions should be evaluated with more rigorous methods and should investigate links between residents' quality of life and quality of patient care.

While exposure to and attitudes about drug company interactions among residents have been studied extensively, relatively little is known about relationships between drug companies and medical students. ⋯ Student experiences and attitudes suggest that as a group they are at risk for unrecognized influence by marketing efforts. Research should focus on evaluating methods to limit these experiences and affect the development of students' attitudes to ensure that physicians' decisions are based solely on helping each patient achieve the greatest possible benefit.
