Articles

  • Ursodiol use appears to be associated with a lower frequency of colonic dysplasia in patients with ulcerative colitis and primary sclerosing cholangitis. A randomized trial investigating the chemoprotective effect of ursodiol in patients with ulcerative colitis may be warranted.

  • Among diabetic women, increased physical activity, including regular walking, is associated with substantially reduced risk for cardiovascular events.

  • Treatment with methotrexate plus corticosteroid is a safe alternative to corticosteroid therapy alone in patients with giant-cell arteritis and is more effective in controlling disease.

Brief Communications

  • Tropheryma whippelii occurs only rarely in intestinal mucosa that lacks histopathologic evidence of Whipple disease. The human small intestinal mucosa is an unlikely reservoir for this organism.

  • Heavy alcohol abuse greatly exacerbates the risk for cirrhosis among patients with hepatitis C virus infection. This finding emphasizes the need to counsel such patients about their drinking habits.

Academia and Clinic

  • The techniques of social marketing—goal identification, audience segmentation, and market research—have not been harnessed and applied to medical education. Social marketing can be applied to medical education in the effort to go beyond inoculation of learners with information and actually change behaviors.

Review

  • This review presents a growing body of evidence suggesting that idiopathic pulmonary fibrosis involves abnormal wound healing in response to multiple, microscopic sites of ongoing alveolar epithelial injury or activation associated with the formation of patchy fibroblast–myofibroblast foci, which evolve to fibrosis.

Perspectives

  • The authors examine the problems underlying recent federal regulatory actions against institutional review boards.

Editorials

  • At present, it would be premature to offer ursodiol as a chemopreventive agent outside the context of a clinical trial. However, if the inverse association between ursodiol use and dysplasia prevalence described by Tung and colleagues in this issue is causal and true, it is a very exciting observation.

  • In this issue, Burman and coworkers identify the enormous increase in the number and complexity of multicenter randomized clinical trials as the root cause of the crisis in institutional review boards (IRBs). This editorial argues that although we must be concerned about the capabilities of IRBs to cope with multicenter trials, IRBs are not the major problem.
