The purpose of our study was to report the results of the implementation of computed tomography colonography in a university hospital setting serving a Brazilian population at high risk of colorectal cancer. ⋯ It was possible to institute an efficient computed tomography colonography service at a university hospital that primarily assists patients from the public health system, with high accuracy, good acceptance and effective radiation doses. Our results seem to be comparable to other centers of excellence and fall within acceptable published guidelines, showing that a successful computed tomography colonography program can be reproduced in a South American population screened in a university hospital.

To describe the profile of physicians working at the Prehospital Emergency Medical System (SAMU) in Brazil and to evaluate their quality of life. ⋯ The doctors in this sample were young and within a few years of graduation, and they had no specific training in prehospital emergencies. Deficiencies were mostly found in pediatrics and psychiatry, with specific deficiencies in the handling of essential equipment and in the skills necessary to adequately attend to prehospital emergencies. A disrespectful labor scenario was also found; the evaluation of quality of life showed a notable presence of pain on the SF-36 among physicians at SAMU and especially among doctors who had worked for a longer length of time at SAMU.

There is no consensus regarding the most appropriate methods (i.e., the side-by-side versus the stent-in-stent technique) for placing bilateral stents for malignant hilar biliary obstructions. We aimed to perform a quantitative review of the published data regarding the clinical efficacy of the side-by-side and stent-in-stent bilateral drainage techniques for hilar biliary obstructions. ⋯ The performance of the side-by-side technique appears to be similar to that of the stent-in-stent technique for bilateral drainage in patients with malignant hilar biliary obstructions.

Review Meta Analysis
Open and endovascular repair of juxtarenal abdominal aortic aneurysms: a systematic review.
This systematic review focuses on the 30-day mortality associated with open surgery and fenestrated endografts for short-necked (<15 mm) juxtarenal abdominal aortic aneurysms. A search for studies published in English and indexed in the PubMed and Medline electronic databases from 2002 to 2012 was performed, using "juxtarenal abdominal aortic aneurysm" and "treatment" as the main keywords. ⋯ No differences were observed regarding the secondary outcomes (duration of surgery, hospital stay, postoperative renal dysfunction and late mortality), except that the late mortality rate was significantly higher for the patients treated with open repair after a median follow-up of 24 months. Fenestrated endografting is a viable alternative to conventional surgery in juxtarenal abdominal aortic aneurysms with a proximal neck <15 mm.

The purpose of this study was to estimate the prevalence of periradicular lesions in HIV-infected Brazilian patients and to assess the correlation of several factors with the periradicular status. ⋯ The prevalence of periradicular lesions in HIV-infected individuals was 46% and was not related to HIV infection.
