NEW YORK, June 28 (Praxis Press) Many treatment options are available for men with prostate cancer but therapeutic recommendations may vary depending on the type of specialist they consult. Fowler and colleagues attempted to define and contrast the distribution of prostate cancer management recommendations given by urologists and radiation oncologists (see paper). To perform the study they mailed a survey to a random sample of physicians in the United States, who were listed as urologists (respo

Depression and mortality

June 27, 2000

NEW YORK, June 27 (Praxis Press) Studies on whether depressive symptoms are associated with mortality in the elderly have yielded contradictory findings. To address these discrepancies, Schulz and colleagues studied a population-based sample of 5201 men and women aged 65 years and older (see paper). They examined depressive symptoms and four categories of covariates at baseline, with the primary outcome measure being mortality after six years. Of the 5201 participants, 984 (18.9%) died within 6

Homocysteine and CAD

June 27, 2000

NEW YORK, June 27 (Praxis Press) Circulating homocysteine levels can be used to predict survival in patients with stable coronary artery disease. The prognostic value of serum homocysteine levels, obtained in the acute phase in patients with myocardial infarction or unstable angina, however, is unknown. To test this hypothesis, Omland and colleagues measured the serum homocysteine levels of a total of 579 patients with Q-wave myocardial infarction (n=163), non- Q-wave myocardial infarction (n=21

NEW YORK, June 27 (Praxis Press) Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) but it is unclear whether specific COX-2 inhibitors are as effective as NSAIDs in the treatment of osteoarthritis (OA). Day and colleagues compared the efficacy and safety of the rofecoxib, which specifically inhibits COX-2, with that of the NSAID ibuprofen in 809 adult patients with OA (see paper. They found that rofecoxib was as effective as ibuprofe

Sigmoidoscopy discomfort

June 27, 2000

NEW YORK, June 27 (Praxis Press) Physicians often cite patient discomfort as a reason for not requesting screening flexible sigmoidoscopy. Patient experiences and attitudes toward sigmoidoscopy, however, have not been well studied. To measure patient satisfaction with screening sigmoidoscopy, Schoen and colleagues surveyed 1221 patients after sigmoidoscopy (see paper). They found that more than 93% of the participants strongly agreed or agreed they would be willing to undergo another examination

Thrombosis treatment

June 27, 2000

NEW YORK, June 27 (Praxis Press) Heparins have been shown to be effective and safe in the treatment of deep vein thrombosis, but the use of this treatment on an outpatient versus an inpatient basis has not been compared. To compare the two treatment locales, Boccalon and colleagues conducted a randomized, comparative, multicenter trial and evaluated the clinical outcomes and treatment costs (see paper). The researchers examined 201 patients with proximal deep vein thrombosis and administered low

Colposcopy guidelines

June 26, 2000

NEW YORK, June 26 (Praxis Press) Currently no guidelines exist for managing women with low grade cytological abnormalities, whose findings on colposcopy do not warrant immediate treatment. To develop an evidence-based protocol for these women, Teale and colleagues evaluated 566 women with low-grade cytological abnormalities who were not treated at a first visit to the colposcopy clinic, and followed them for a total of 881 years (see paper). Abnormalities resolved in 306 (54.1%) women, whereas 1
