OBJECTIVES:The aim of this study was to report the type and frequency of ocular manifestations in Brazilian psoriatic arthritis patients.METHODS:We conducted a cross-sectional study in a Brazilian tertiary hospital. The test group included 40 patients who had psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis. A control group of 40 individuals was matched for age and gender. All of the patients underwent ophthalmic evaluation, which included best-corrected visual acuity, slit lamp and fundus examinations, and dry eye diagnostic tests (Schirmer I, tear break-up time and rose bengal). Demographic parameters were also evaluated.RESULTS:The mean age of the patients was 53.9±13.1 years; the mean disease duration was 8±10.5 years. Most of the patients were women (60%), and the majority had polyarticular disease (57.5%). Several ocular abnormalities were found, including punctate keratitis, pinguecula, blepharitis, pterygium, cataract, glaucoma, uveitis, and retinal microvascular abnormalities. There were no significant differences in the rates of these abnormalities compared with the control group, however. The Keratoconjunctivitis sicca and dry eye diagnostic tests were more often positive in the patients with psoriatic arthritis than in the control group.CONCLUSIONS:In this study, keratoconjunctivitis sicca was the most common ocular finding related to psoriatic arthritis. Therefore, we recommend early ophthalmologic evaluations for all psoriatic arthritis patients who complain of eye symptoms.
As escolas médicas brasileiras priorizam o ambiente hospitalar para o ensino e acabam formando profissionais carentes de compromisso social. O curso de Medicina da Universidade Federal de Santa Maria implantou, em 2004, um novo currículo que inclui o Internato Regional (IR), em que o interno permanece dois meses em município conveniado, atuando em atenção primária em saúde. Este estudo transversal e quanti-qualitativo teve por objetivo conhecer a percepção dos acadêmicos da primeira turma que realizou o IR sobre o impacto desse modelo de estágio em sua formação, mediante a aplicação de um questionário semiestruturado. Mais de 75% das respostas apontaram ter havido contribuição para maior conhecimento da realidade social e profissional, aprimoramento da relação médico-paciente e desenvolvimento de autoconfiança no exercício da profissão. O principal ponto negativo ressaltado foi o despreparo dos médicos-preceptores para atuar como docentes. No atual contexto de mudanças, o IR surge como uma proposta satisfatória de ampliação dos cenários de prática-ensino-aprendizagem e contribui com a formação humana e pessoal dos futuros médicos, apesar de ainda carecer de preceptoria qualificada.
Psoriasis and psoriatic arthritis are complex and heterogeneous clinical entities, whose presentations comprise multiple combinations of subtypes. There are doubts even if they are distinct entities or merely variants of the same disease. Epidemiologically, psoriasis can be considered a common disease because it affects about 2% of the world population. Regarding psoriatic arthritis, there is no consensus in the literature about its true incidence and prevalence in the general population. Genetic, immune, and environmental factors interact culminating in skin and joint manifestations of psoriatic disease. The central role of activated T lymphocytes in the pathogenesis of both psoriasis and psoriatic joints is now recognized. Furthermore, proinfl ammatory cytokines can be found in increased concentrations in both skin and synovium of patients with psoriatic arthritis. Since 1964, when the relationship between psoriasis and psoriatic arthritis was recognized, many studies have been conducted to better understand the common mechanism of both diseases. The HLA has already been considered the center of the psoriatic arthritis immunopathogenesis; today, TNF-α plays such a role. This paper is a review of various factors associating psoriasis and psoriatic arthritis leading to the hypothesis of a single disease with multiple presentations.
BACKGROUNDHLA-B27 is associated with spondyloarthritis, a group of diseases that includes psoriatic arthritis. OBJECTIVESTo describe the HLA-B27 frequency in a group of Brazilian patients with psoriatic arthritis and correlate its presence or absence with their clinical manifestations. METHODSCross-sectional study with 44 psoriatic arthritis patients of a Rheumatology clinic. Demographic and social data were recorded, as were skin and joints clinical examination. HLA-B27 was tested. All data were processed descriptively and comparatively by appropriate software. Parametric and non parametric tests were used with 5% statistical significance. RESULTSHLA-B27 was negative in 32 of the 44 patients (72,7%). Most of them were male, Caucasian, living in Rio de Janeiro, with plaque type psoriasis and average age of 52,9 years. There was statistical significant correlation between positive HLA-B27 and male gender (p=0,004). Negative HLA-B27 had a tendency to correlate with hands and wrists arthritis (p=0,07). There was an inverse significant correlation between HLA values and Schöber's test (p=0,02). CONCLUSIONAlthough HLA-B27 is negative in most of patients, it is significantly associated to male gender and inversely correlated with Schöber's test.
