Résumé
This study investigates the frequency of Torque teno virus (TTV) infection in 150 blood donors and 77 patients requiring haemodialysis in southern Brazil. Plasma samples were screened for TTV DNA using polymerase chain reaction (PCR). The prevalences of TTV among blood donors and patients requiring haemodialysis were 73.3% and 68.8%, respectively. The presence of TTV was correlated with age in the blood donors (p = 0.024). In haemodialysis patients, no association was found between TTV infection and the demographic parameters (age, sex and education), the duration of haemodialysis or a history of blood transfusion. This study is the first to evaluate the prevalence of TTV infection in Brazilian patients requiring haemodialysis.

Non-Hodgkin´s lymphoma of the spermatic cord are rare. There is the registration of 14 (fourteen) cases of spermatic cord lymphoma in the literature, all treated with radical orchiectomy with or without radiotherapy. The adjuvant chemotherapy still is not a consensus, therefore the therapy must be individualized and applied according to the stage of the disease. The present study report a new case of primary non-Hodgkin´s lymphoma of the spermatic cord treated with radical orchiectomy through inguinal via with precocious ligature of the spermatic cord and adjuvant chemotherapy. Presently found with 2 and a half years of follow-up without recidivation clinical evidence, as the image exams show to be normal.

Os autores descrevem o achado de um raro caso de neoplasia benigna da vesícula biliar, qual seja, o de um hemangioma à cavernoso mural. Essa neoplasia foi encontrada num paciente masculino, com sangramentos digstivos de repetiçåo, com estudo endoscópio digestivo alto normal, dois meses após o último sangramento, constituindo-se num achado ocasional de colecistectomia indicada por quadro agudo
