  • Golpe de Calor - dois casos clínicos
    Publication . Nascimento, J.; Sarmento, A.; Rocha, S.; Gonçalves, S.; Marcelino, F.; Ferreira, P.
    O golpe de calor é uma emergência médica caracterizada por uma temperatura central ≥ 40ºC, associada a resposta inflamatória sistémica que conduz a disfunção multiorgânica onde predomina a encefalopatia. A incidência é desconhecida, uma vez que é sub-diagnosticada. Os autores apresentam dois casos internados no Serviço de Cuidados Intensivos Pediátricos no período de um ano.

  • Anti-Ro52 Antibodies and Interstitial Lung Disease in ConnectiveTissue Diseases Excluding Scleroderma
    Publication . Ferreira, J.; Almeida, I.; Marinho, A.; Cerveira, C.; Vasconcelos, C.
    The presence of anti-Ro52 antibodies has been reported in a wide variety of autoimmune diseases, particularly in myositis, scleroderma, and autoimmune liver diseases. Clinical significance of anti-Ro52 antibodies remains controversial, and studies are lacking for clarifying the association of anti-Ro52 with interstitial lung disease (ILD) in connective tissue diseases (CTD). Objectives. To determine if anti-Ro52 antibodies are associated with ILD in CTD other than scleroderma. Methods. Singlecenter, retrospective study based on immunoblotting panel analysis and patients clinical records. Results. In our connective tissue disease cohort, 162 patients had immunoblotting panels with anti-Ro52 reactivity analysis, 41 (25,3%) had inclusion criteria. Among the 41 selected sera, 85.4% (n = 35) had anti-Ro52 reactivity. The prevalence of ILD in the positive anti-Ro52 antibodies was 71.4% (n = 25), and 16.7% (n = 1) in the negative anti-Ro52 group (P = 0.018). Overall sensitivity (96.2%), specificity (83.3%), positive (71.4%) and negative (83.3%) predictive values of anti-Ro52 antibodies to determine ILD in CTD is detailed in this study. Conclusion. Ro52 autoantibodies are associated with ILD in CTD excluding scleroderma. We suggest that the presence of anti-Ro52 reactivity in CTD should increase the clinician curiosity for the search of ILD.
