  • Interpretação de artefacto radiológico de grandes dimensões localizado na bacia
    Publication . Judas, F; Rodrigues, S; Carvalhais, P; Matos, P
    presença de artefactos nas radiografias da bacia pode ocultar anomalias ou criar falsas imagens que conduzem a interpretações erradas e a consequências indesejáveis. A maioria dos artefactos são imediatamente reconhecidos e não acrescentam dificuldade para o diagnóstico; outros podem ser interpretados como falsas lesões ou mascarar verdadeiras lesões. Os artefactos podem ser causados pelo doente, pelo equipamento, pelo processamento da imagem ou pelo próprio processador. Apresentamos o caso de um doente que foi submetido a exame radiológico devido a uma bursite trocantérica sintomática. Observou-se uma imagem radiográfica incomum, de grandes dimensões, na hemipélvis esquerda, que poderia ser interpretada como uma massa de tipo tumoral, apesar da anamnese e do exame físico terem previamente excluído essa hipótese de diagnóstico. Uma nova radiografia da bacia demonstrou que se tratava de uma falsa imagem, um artefacto causado por erro técnico.

  • Ulcerative colitis in a Southern European country: a national perspective
    Publication . Portela, F; Magro, F; Lago, P; Cotter, J; Cremers, I; Deus, J; Veiria, A; Lopes, H; Caldeira, P; Barros, L; Reis, J; Carvalho, L; Gonçalves, R; Campos, MJ; Ministro, P; Duarte, MA; Amil, J; Rodrigues, S; Azevedo, L; Costa-Pereira, A
    BACKGROUND: The incidence, prevalence, and even the clinical behavior of ulcerative colitis (UC) are highly variable in different world regions. In previous studies, Portugal was reported as having a milder clinical behavior. The aim of this study was to apply the Montreal Classification in a large group of UC Portuguese patients in order to describe their clinical characteristics and evaluate variables potentially useful for outcome prediction. METHODS: A cross-sectional study based on data collected from a nationwide online registry was undertaken. RESULTS: In all, 2863 patients with UC were included. Twenty-one percent had ulcerative proctitis, 52% left-sided colitis, and 28% extensive colitis. Sixty percent of patients had taken steroids, 14% immunosuppressors, 1% biologicals, and 4.5% were submitted to surgery. Patients with extensive colitis had more severe activity, needing more steroids, immunosuppressors, and surgery. At the time of diagnosis 61% were less than 40 years old and 5% less than 16. Younger patients also had a more aggressive initial course. Thirty-eight percent of patients had only taken salicylates during the disease course and were characterized by a lower incidence of systemic symptoms at presentation (3.8% versus 8.8%, P < 0.001), fewer extraintestinal manifestations (7.7% versus 24.0%, P < 0.001), and a higher prevalence of proctitis (32.1% versus 10.0%). CONCLUSIONS: A more aggressive phenotype was found in extensive colitis and in the initial course of younger patients, with an increased need for steroids and immunosuppressors. In addition, a significant percentage of patients, particularly with proctitis, showed a milder clinical evolution and were maintained in remission only with salicylates.

  • Ulcerative colitis in northern Portugal and Galicia in Spain
    Publication . 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, A
    BACKGROUND: 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
