Articles

  • The incidence of second primary colorectal cancer after treatment for localized colon cancer remains high despite intensive surveillance strategies.

  • A deteriorating effect of severe α1-antitrypsin deficiency (ZZ genotype) on lung function is well known, whereas the role of intermediate deficiency (MZ genotype) remains uncertain. This study found that MZ heterozygotes had a slightly greater rate of decrease in FEV1 and were modestly over-represented among persons with airway obstruction and chronic obstructive pulmonary disease (COPD). In the population at large, MZ heterozygosity may account for a fraction of COPD cases—on the order of 2%, similar to the percentage of persons with COPD who have the severe but rare ZZ genotype.

  • A positive result on the stool antigen test 7 days after completion of therapy identifies patients in whom eradication of Helicobacter pylori was unsuccessful.

Brief Communications

  • Most patients with hepatitis C virus infection are not candidates for interferon-based therapies; alternative interventions should be sought for these patients.

Review

  • Suicide is generally a complication of a psychiatric disorder, but it requires additional risk factors because most psychiatric patients never attempt suicide. This review includes a hypothesized stress–diathesis model, which has implications for detection of high-risk patients and treatment interventions, and discusses promising treatment approaches.

Medicine and Public Issues

  • This paper summarizes the current status of concerns about the safety of the blood supply in developed countries, where viral transmission from contaminated blood or blood products is extremely rare, and in developing countries, where up to 10% of HIV infections result from transfusion of blood or blood products.

NIH Conferences

  • In the past 50 years, since the discovery of cortisone therapy as an effective treatment for congenital adrenal hyperplasia, many advances have been made in the study and management of 21-hydroxylase deficiency. The discovery of the 21-hydroxylase gene was followed by the discovery of the 21-hydroxylase–deficient mouse, which has provided a useful model for testing new treatments. As our knowledge of this disease expands, new therapies are being developed and tested in both humans and animals.

Editorial

  • Although the study by Green and colleagues in this issue chronicles a disturbingly high rate of second primary colorectal cancer in patients undergoing surveillance in an adjuvant chemotherapy trial, the junctures at which corrective measures are most needed cannot be precisely determined. For now, adherence to the existing consensus guidelines for postoperative surveillance seems warranted until convincing evidence supports alternative strategies.
