- Artropatia dos joelhos como manifestação inicial de neoplasia pulmonarPublication . Inês, L; Santos, MJ; Silva, C; Braña, A; Nour, D; Reis, P; Malcata, AB; Porto, AApresentamos o caso de uma doente de 46 anos que recorreu ao serviço de urgência por dor e tumefacção dos joelhos com 3 meses de evolução. Na subsequente observação em Reumatologia identificou--se a presença de baqueteamento digital nas mãos e pés (com cerca de 1 ano de evolução) e edema dos membros inferiores. As radiografias dos ossos longos demonstraram a presença de periostose. A investigação de causas de osteoartropatia hipertrófica secundária revelou a existência de uma neoplasia pulmonar volumosa, que não apresentou no exame clínico quaisquer manifestações respiratórias.
- Differential male and female adrenal cortical steroid hormone and cortisol responses to interleukin-6 in humansPublication . Silva, C; Inês, L; Nour, D; Straub, RH; Pereira da Silva, JAEvidence from experimental animal studies show that sex hormones influence the glucocorticoid response to a variety of inflammatory and noninflammatory stimuli. In this study we assessed gender differences in the response of ACTH and cortisol in normal young male and female humans following intravenous infusion of human IL-6 in various dosages. Males presented a significantly stronger ACTH production in response to IL-6 than females. Peak cortisol response, however, was similar in males and females. Cortisol/ACTH ratios were significantly higher in females than in males, both at baseline and after each of the IL-6 dosages. These results suggest that an effective glucocorticoid response requires similar levels of IL-6 in males and females. However, they also suggest that the adrenals of males and females have different sensitivities to ACTH (higher in females) and possibly also to direct IL-6 stimulation.
- Neuro-Behçet: A Clinical ExercisePublication . Oliveira, MA; Pereira da Silva, JA; Nour, D; Macário, MC; Malcata, AB; Porto, A; Siva, A; Yazici, HBehçet disease is a recurrent systemic vasculitis of unknown etiology, that involves vessels of nearly all sizes and types. Because of this, disease manifestations can occur at many sites throughout the body. Central nervous system (CNS) involvement may be parenchymal or nonparenchymal and has a global prevalence that ranges from 3% to 10%. Main signs of CNS involvement are pyramidal and those resulting from brain stem lesions. Aseptic meningitis, mental changes, sphincter disturbances, pseudobulbar syndrome, and deep sensory abnormalities may be seen. Analysis of cerebrospinal fluid, computed tomography (CT), magnetic resonance imaging (MRI), single-photon emission computed tomography (SPECT) and brain angiography offer assistance in the diagnosis. The course of disease can be primary progressive, secondary progressive or have a relapsing-remitting profile. Boluses of methylprednisolone for three days followed by cyclophosphamide are the treatment of choice. This papers discusses these aspects of neuro-Behcet on the basis of complex clinical case
