ABSTRACT
ABSTRACT The aim of this report is to present an unusual case of Crohn's disease affecting the terminal ileum; whose principal differential diagnosis was Yersinia enterolocolitica infection, as the histological features of the resected ileum was common to both diseases. We also describe how the infectious etiology was discarded and the implications for the patient follow-up.
RESUMO O objetivo desse relato é analisar um caso incomum de doença de Crohn, cujo diagnóstico diferencial, com possível infecção por Yersinia enterocilítica, foi dificultado pela presença de alterações histológicas das duas doenças. Descrevemos como foi realizada a exclusão de causas infecciosas e as implicações no acompanhamento do paciente.

There is increasing interest in the identification of factors associated with liver disease progression in patients infected with hepatitis C virus (HCV). We assessed host-related factors associated with a histologically advanced stage of this disease and determined the rate of liver fibrosis progression in HCV-infected patients. We included patients submitted to liver biopsy, who were anti-HCV and HCV RNA positive, who showed a parenteral risk factor (blood transfusion or intravenous drug use), and who gave information about alcohol consumption.Patients were divided into two groups for analysis: group 1 - grades 0 to 2; group 2 - grades 3 to 4. The groups were compared in terms of sex, age at the time of infection, estimated duration of infection and alcoholism. The rate of fibrosis progression (index of fibrosis) was determined based on the relationship between disease stage and duration of infection (years). Logistic regression analysis revealed that age at the time of infection (P<0.01; 95 percent CI 1.06-1.22) and the duration of infection (P<0.01; 95 percent CI 1.06-1.32) were independently associated with a more advanced stage of hepatitis C. The median index of fibrosis was 0.14 for the group as a whole. A significant difference in the index of fibrosis was observed between patients aged < 40 years at infection (median = 0.11) and patients aged > or = 40 years (median = 0.47). The main factors associated with a more rapid fibrosis progression were age at the time of infection and the estimated duration of infection. Patients who acquired HCV after 40 years of age showed a higher rate of fibrosis progression

A síndrome de Peutz-Jeghers é uma doença rara de padräo autossômico dominante, com alta penetrância, apresentando manchas cutâneas e pólipos hamartomatosos. É relatada a ocorrência da síndrome com adenocarcinoma na segunda porçäo do duodeno, em um paciente jovem, com metástase hepática e infiltraçäo pancreática. A freqüência desta associaçäo é estimada em torno de 5 por cento dos portadores da síndrome. Tal associaçäo é rara e é discutida a possibilidade de pólipo adenomatoso sofrer degeneraçäo maligna, do hamartoma apresentar transformaçäo cancerosa ou a coexistência de adenoma entre os pólipos hamartomatosos
