OBJECTIVE To assess whether patients with psoriasis treated with tumor necrosis factor (TNF) inhibitors have a decreased risk of myocardial infarction (MI) compared with those not treated with TNF inhibitors. DESIGN Retrospective cohort study. SETTING Kaiser Permanente Southern California health plan. ⋯ The incidence of MI in the TNF inhibitor, oral/phototherapy, and topical cohorts were 3.05, 3.85, and 6.73 per 1000 patient-years, respectively. CONCLUSIONS Use of TNF inhibitors for psoriasis was associated with a significant reduction in MI risk and incident rate compared with treatment with topical agents. Use of TNF inhibitors for psoriasis was associated with a non-statistically significant lower MI incident rate compared with treatment with oral agents/phototherapy.

OBJECTIVE To summarize and critically appraise the evidence on the measurement properties of clinician-, patient-, and observer-reported outcomes, measuring any construct of interest in patients with all types of vitiligo. DATA SOURCES Electronic databases including PubMed (1948 to July 2011), OVID EMBASE (1980 to July 2011), and CINAHL (EBSCOhost) (1982 to July 2011) were searched. STUDY SELECTION Two authors independently screened all records for eligibility. ⋯ For other instruments, the evidence of measurement properties was limited or unknown. CONCLUSIONS Recommendations on the use of specific outcome measures for vitiligo should be formulated with caution because current evidence is insufficient owing to a low number of studies with poor methodological quality and unclear clinical relevance. To recommend outcome measures for vitiligo, further research on measurement properties of clinical relevant outcome measures for vitiligo according to COSMIN quality criteria is needed.
