Colonic angiodysplasia on CT colonography: case report and characteristic imaging findings.

Gastrointestinal angiodysplasia represents the cause of 6% of lower gastrointestinal tract bleeding, particularly in the elderly. Because of the common presentation and age range of affected patients, often patients with occult or massive gastrointestinal bleedings are investigated with colonoscopy, in the suspect of colonic cancer. Other methods are capsule enteroscopy, angiography, double-contrast barium enema, computed tomography angiography, and radionuclide scanning.

Computed tomography (CT) virtual autopsy and classical autopsy discrepancies: radiologist's error or a demonstration of post-mortem multi-detector computed tomography (MDCT) limitation?

Modern imaging technologies, such as computed tomography (CT) techniques, represent a great challenge in forensic pathology. The field of forensics has experienced a rapid increase in the use of these new techniques to support investigations on critical cases, as indicated by the implementation of CT scanning by different forensic institutions worldwide. Advances in CT imaging techniques over the past few decades have finally led some authors to propose that virtual autopsy, a radiological method applied to post-mortem analysis, is a reliable alternative to traditional autopsy, at least in certain cases.

[An integrated model for the evaluation and risk management of tuberculosis infection and active tuberculosis in homeless people in the city of Rome (Italy)].

In this article we describe an integrated model for the evaluation and risk management of tuberculosis (TB) infection and active TB in socially disadvantaged populations in the city of Rome. We describe and discuss the clinical evaluation procedures performed and the data collection forms used; these tools are useful for the epidemiologic surveillance and clinical management of patients, particularly high risk patients such as the homeless.

Intralobar pulmonary sequestration in an elderly adult.

The case of a patient admitted to the hospital for symptoms characterized by chest pain, productive cough, fever, dyspnea resistant to antibiotic therapy is discussed. Previous plain chest X-ray performed elsewhere was suggestive of inflammotory lung consolidation. An admission chest X-ray revealed a left lower lobe density.
