Author self-citation is the practice of citing one's previous publications in a new publication. Its extent is unknown. We studied author self-citation, choosing the major clinical field of diabetes mellitus to represent the general medical literature. ⋯ Nearly one-fifth of all citations to articles about diabetes mellitus in clinical journals in the year 2000 were author self-citations. The frequency of self-citation was not associated with the quality of publications. These findings are likely applicable to the general clinical medicine literature and may have important implications for the assessment of journal or publication importance and the process of scientific discovery.

Multicenter Study
Career choice of new medical students at three Canadian universities: family medicine versus specialty medicine.
Over the last 10 years the number of medical students choosing family medicine as a career has steadily declined. Studies have demonstrated that career preference at the time that students begin medical school may be significantly associated with their ultimate career choice. We sought to identify the career preferences students have at entry to medical school and the factors related to family medicine as a first-choice career option. ⋯ Several factors appear to drive students toward family medicine, most notably having a societal orientation and a desire for a varied scope of practice. If the factors that influence medical students to choose family medicine can be identified accurately, then it may be possible to use such a model to change medical school admission policies so that the number of students choosing to enter family medicine can be increased.

Psoriasis is an immune-mediated skin disease in which chronic T-cell stimulation by antigen-presenting cells (APC) occurs in the skin. This interplay between the T-cell and APC has been likened to a "T-AP dance" where specific steps must occur in sequence to result in T-cell activation and the disease phenotype; otherwise T-cell anergy would occur. ⋯ These medications act at specific steps during the T-AP dance either to inhibit T-cell activation, costimulation and subsequent proliferation of T-cells, lead to immune deviation or induce specific cytokine blockades. The potential increased selectivity for specific pathways in immune activation, clinical efficacy and relative safety of these new agents offers an alternative for the treatment of moderate to severe psoriasis.

Effect of patient socioeconomic status on perceptions of first- and second-year medical students.
Physician decision-making and perceptions of patients are affected by a patient's socioeconomic status (SES). We sought to determine if the perceptions of first- and second-year medical students are similarly affected. We also wanted to determine whether a student's own SES affects his or her perceptions of patients from a low or high SES background. ⋯ First- and second-year medical students have negative perceptions of low SES patients on several dimensions.
