In patients with a low clinical probability of pulmonary embolism (PE) and a nondiagnostic lung scan, the prevalence of PE is theoretically very low. We assessed the safety and usefulness of this association for ruling out PE. ⋯ Anticoagulant treatment could be safely withheld in patients with a low clinical probability of PE and a nondiagnostic lung scan, provided that the US is normal. This combination of findings avoided pulmonary angiography in 21.5% of patients with suspected PE in this series.

The prevalence of abnormal thyroid function in the United States and the significance of thyroid dysfunction remain controversial. Systemic effects of abnormal thyroid function have not been fully delineated, particularly in cases of mild thyroid failure. Also, the relationship between traditional hypothyroid symptoms and biochemical thyroid function is unclear. ⋯ The prevalence of abnormal biochemical thyroid function reported here is substantial and confirms previous reports in smaller populations. Among patients taking thyroid medication, only 60% were within the normal range of TSH. Modest elevations of TSH corresponded to changes in lipid levels that may affect cardiovascular health. Individual symptoms were not very sensitive, but patients who report multiple thyroid symptoms warrant serum thyroid testing. These results confirm that thyroid dysfunction is common, may often go undetected, and may be associated with adverse health outcomes that can be avoided by serum TSH measurement.

Comparative Study
Prevalence and content analysis of guidelines on handling requests for euthanasia or assisted suicide in Dutch nursing homes.
The growing number of requests for euthanasia or assisted suicide (EAS) makes it imperative for health care institutions, such as nursing homes, to have written guidelines on how to handle requests for EAS. The objective of this study was to determine the prevalence of EAS guidelines in Dutch nursing homes and to analyze the content. ⋯ Despite the rapidly growing number of nursing-home guidelines on EAS and the existence of model documents, there is still considerable variation in the guidelines, and they can be improved in many aspects. A basic prerequisite is that the guidelines include all the official requirements for prudent practice.

Comparative Study
A nationwide study of decisions to forego life-prolonging treatment in Dutch medical practice.
Decisions to withhold or withdraw life-prolonging treatment in terminally ill patients are common in some areas of medical practice. Information about the frequency and background of these decisions is generally limited to specific clinical settings. This article describes the practice of withholding or withdrawing life-prolonging treatment in the Netherlands. ⋯ Decisions to forego life-prolonging treatment are frequently made end-of-life decisions in the Netherlands and may be increasing. Most of these decisions do not involve high-technology treatments, and the consequences, in terms of shortening of life, are relatively small.

Declines in human immunodeficiency virus (HIV)-related mortality between 1995 and 1996 were seen across the United States but were small to nonexistent among people in marginalized sectors who are most likely to contract HIV and die of its effects. No comprehensive analysis describing HIV-related mortality in 1997 was available. ⋯ The HIV-related mortality has fallen dramatically in Chicago since 1995, the year of its maximum. During 1997, declines were seen among all groups. Declines were also seen among the most disenfranchised of the city. Access to care and the new combination therapies are apparently sustaining life for many in Chicago.
