- Epidermal nevus syndrome: an unusual cerebellar involvementPublication .

- Traumatic middle cerebral artery aneurysm secondary to a gunshot wound.Publication . Santos, G; Lima, T; Pereira, S; Macahdo, ETraumatic intracranial aneurysms are rare lesions, accounting for less than 1% of all intracranial aneurysms. Formation of these lesions after a penetrating missile wound is very unusual, and diagnosis can be difficult due to the presence of associated lesions. In this article, we report a case of a woman who developed a middle cerebral artery aneurysm after a gunshot wound, and discuss potential pitfalls found during diagnostic work-up.
- Ulcerative colitis in northern Portugal and Galicia in SpainPublication . Barreiro-da-Costa, M; Magro, F; Carpio, D; Lago, P; Echarri, A; Cotter, J; Pereira, S; Gonçalves, R; Lorenzo, A; Carvalho, L; Castro, J; Barros, L; Dias, JA; Rodrigues, S; Portela, F; Dias, C; Costa-Pereira, ABACKGROUND: Clinical and therapeutic patterns of ulcerative colitis (UC) are variable in different world regions. The purpose of this study was to examine two close independent southern European UC populations from 2 bordering countries and observe how demographic and clinical characteristics of patients can influence the severity of UC. METHODS: A cross-sectional study was conducted during a 15-month period (September 2005 to December 2006) based on data of 2 Web registries of UC patients. Patients were stratified according to the Montreal Classification and disease severity was defined by the type of treatment taken. RESULTS: A total of 1549 UC patients were included, 1008 (65%) from northern Portugal and 541 (35%) from Galicia (northwest Spain). A female predominance (57%) was observed in Portuguese patients (P < 0.001). The median age at diagnosis was 35 years and median years of disease was 7. The majority of patients (53%) were treated only with mesalamine, while 15% had taken immunosuppressant drugs, and 3% biologic treatment. Most patients in both groups were not at risk for aggressive therapy. Extensive colitis was a predictive risk factor for immunosuppression in northern Portugal and Galicia (odds ratio [OR] 2.737, 95% confidence interval [CI]: 1.846-4.058; OR 5.799, 95% CI: 3.433-9.795, respectively) and biologic treatment in Galicia (OR 6.329, 95% CI: 2.641-15.166). Younger patients presented a severe course at onset with more frequent use of immunosuppressors in both countries. CONCLUSIONS: In a large population of UC patients from two independent southern European countries, most patients did not require aggressive therapy, but extensive colitis was a clear risk factor for more severe disease
