OBJECTIVE: Recent studies suggest antinuclear antibodies (ANA) may be related to mortality risk, but evidence is sparse and inconclusive. Thus, we investigated ANA associations with all-cause and cause-specific mortality in U.S. adults. METHODS: Our sample included 3357 adults (ages ≥20 years) from the 1999-2004 National Health and Nutrition Examination Survey with ANA measurements (1:80 dilution) and mortality data through 2011 (median follow-up: 9.4 years). We estimated hazard ratios (HRs) and 95% confidence intervals (CIs) via weighted Cox regression to assess ANA associations with mortality from all causes, cardiovascular disease (CVD), and cancer...

Introduction Chronic cutaneous lupus erythematosus (CCLE) usually presents as characteristic erythematous patches and infiltrated coin-shaped plaques. However, there are some atypical clinical variants that may mimic other dermatological conditions. Haroon et al. reported in 1972 an unusual presentation of CCLE with hypertrophic follicular scars seen in acne vulgaris. Acneiform presentation is one of the most rarely reported and one of the most confusing, as it resembles a very common inflammatory skin disease...

Mercury (Hg) is a well-known neurotoxin, and has been more recently studied specifically as an immunotoxin. In experimental and a few epidemiologic studies, Hg has been associated with distinct cytokine profiles and antinuclear antibody (ANA) positivity, though patterns at lower levels of exposure, typical of seafood consumers with a western diet, are not well characterized. Seafood consumers (n=287) recruited on Long Island, NY completed food frequency and health questionnaires and provided blood for analysis of Hg, poly-unsaturated fatty acids (omega-3 and omega-6 fatty acids), selenium (Se), ANA, and several cytokines (IL-1β, IL-4, IL-10, TNF-α, IL-17, IFN-γ, and IL-1ra)...

Dear Editor, Scleroderma associated with neoplasia is rare, with only a small number of cases reported. We describe 4 patients with paraneoplastic scleroderma who were treated at the I. Department of Dermatovenereology, St. Anna Hospital, during the period between 2004 and 2014. The patients were diagnosed with cholangiogenic carcinoma, endometrial carcinoma, prostatic adenocarcinoma, and adenoma of the suprarenal gland. In the case of concurrent scleroderma and tumor, four situations may occur: they can develop independently of each other; scleroderma may be induced by the tumor; the tumor can develop in the scleroderma; or the tumor can be induced by immunosuppressive therapy...
