- Gangrena de Fournier numa MulherPublication . Murinello, A; Figueiredo, AM; Athayde, M; Grima, B; Ribeiro, V; Lourenço, S; Fernandes, C; Goja, M; Coleho, JFA fasceíte necrotizante dos tecidos infra-diafragmáticos (gangrena de Fournier) é uma grave infecção sinergística por agentes aeróbicos/anaeróbicos, com uma evolução clínica súbita e rápida de gangrena da fascia e sepsis generalizada, associada a elevada mortalidade. Trata-se de uma emergência médico-cirúrgica necessitando de tratamento intensivo englobando a correcção das anomalias hemodinâmicas, hidroelectrolí- ticas e metabólicas, antibioterapia dupla/tripla de largo espectro por via endovenosa, desbridamento cirúrgico agressivo do tecido necrótico infectado e correcção da determinante etiológica da gangrena. É frequente encontrar como factores de risco a diabetes mellitus, doença crónica hepática, doenças malignas, doenças imunológicas congénitas ou adquiridas, tratamento com fármacos imuno-supressores, alcoolismo crónico e má nutrição. As fontes infecciosas originais conducentes a uma gangrena de Fournier são geralmente abcessos da área peri-anal ou processos infecciosos genitourológicos. Embora a gangrena de Fournier seja muito menos frequente na mulher que no homem, é importante pensar nesse diagnóstico, de forma a proporcionar às doentes a possibilidade de tratamento com sucesso. Descreve-se o caso de uma gangrena de Fournier, determinada porumabscesso da fossa ísquio-rectal, numa mulher diabética e em tratamento de um penfigus vulgaris com fármacos imuno-supressores, com evolução fatal, possivelmente em resultado de diagnóstico e tratamento tardios.
- Leprosy and Rheumatoid Arthritis: Consequence or Association?Publication . Coelho Henriques, C; Lopéz, B; Mestre, T; Grima, B; Panarra, A; Riso, NLeprosy or Hansen's disease is a chronic granulomatous infectious disease caused by Mycobacterium leprae with a high prevalence in some developing countries however, it is rarely seen in non-endemic regions. Arthritis has been described in all types of Hansen's disease. Chronic arthritis is known to exist even in paucibacillary forms, resolved or treated disease and in patients without reaction, suggesting a perpetuated inflammatory process. In these cases leprosy can mimic some autoimmune diseases such as rheumatoid arthritis. When a patient with a history of leprosy presents with a symmetric, distal, polyarthritis the diagnosis may not be linear. Possibly it is a rheumatoid-like leprous arthritis with M leprae acting as the trigger element for the chronic process or it is an overlap condition, with a concomitant rheumatoid arthritis? A case report of a patient with a chronic inflammatory arthritis with 10 years of evolution is presented. The differential diagnosis between leprous and rheumatoid arthritis is discussed.
- Personality, Brain Asymmetry, and Neuroendocrine Reactivity in Two Immune-Mediated Disorders: a Preliminary ReportPublication . Martin Martins, J; Alves, J; Trinca, A; Grima, B; Vale, S; Vasconcelos, T; Riso, N; Vaz Riscado, M; Charneco da Costa, JDevelopment of some immune-mediated disorders may depend on dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. To explore neuropsychologic mechanisms in relation to the abnormal endocrine reactivity in patients with systemic lupus erythematosus (SLE) and chronic hepatitis C (CHC) we used the corticotropin releasing hormone (CRH) test, the Minnesota Multiphasic Personality Inventory (MMPI), and the Edinburgh Inventory of Manual Preference Inventory (EIMP). Compared to controls, the adrenocorticotrophic hormone (ACTH) response to CRH was reduced in CHC, while SLE presented reduced baseline dehydroepiandrosterone sulfate levels; higher neurotic scores were found in SLE and higher behavior deviant scores in CHC. Peak ACTH levels were a significant factor for the MMPI profile variability, while the manual preference score was a significant factor for the ACTH response. Personality and manual preference contribute to neuroendocrine abnormalities. Different behavioral and neuroimmunoendocrine models emerge for these disorders.
