CT angiography for acute gastrointestinal bleeding: what the radiologist needs to know.

Acute gastrointestinal (GI) bleeding is a common cause of both emergency department visits and hospitalizations in the USA and can have a high morbidity and mortality if not treated rapidly. Imaging is playing an increasing role in both the diagnosis and management of GI bleeding. In particular, CT angiography (CTA) is a promising initial test for acute GI bleeding as it is universally available, can be performed rapidly and may provide diagnostic information to guide management.

Trends in survival after childhood cancer in Europe, 1978-1997: report from the Automated Childhood Cancer Information System project (ACCIS).

This study, originating in the Automated Childhood Cancer Information System (ACCIS), evaluated the time trend in survival after childhood cancer in Europe. The study included more than 72,000 childhood cancer cases aged 0-14 years diagnosed in 1978-1997 and followed-up in 30 population-based cancer registries with a long history of registration and follow-up, in 15 European countries. Survival was analysed using an actuarial life-table method.

Periaortic lymphoma as a mimic of posttraumatic intramural hematoma.

Computed tomography (CT) of an 87-year-old man who presented to the emergency department with chest pain after a motor vehicle collision demonstrated multiple broken ribs and a thoracic periaortic soft tissue mass which was high density on precontrast images and enhanced postcontrast. The scan also demonstrated a mass encircling the left ureter and masses in the axilla and pelvis. The enhancement of the periaortic lesion and the presence of the additional soft tissue masses suggested lymphoma as opposed to intramural hematoma (IMH).

Rectal inflammation as first manifestation of graft-vs-host disease: radiologic-pathologic findings.

Graft-vs-host disease (GVHD) is a common, life-threatening complication of bone marrow transplantation that frequently involves the gastrointestinal tract. Since symptoms are typically nonspecific, radiologic examination is often performed to reach a diagnosis. To the best of our knowledge, this is the first reported radiologic description of a case of rectal involvement as the first manifestation of GVHD.

Life expectancy as an indicator of outcome in follow-up of population-based cancer registries: the example of childhood leukemia.

Background: Survival analysis is a standard methodology to assess progress in oncology disease treatment. However, survival analysis commonly only measures survival during the treatment period (and the period immediately afterwards), and does not provide an estimate of life expectancy, which is often of more interest to patients and to health policy makers. In this paper we propose a method to estimate childhood acute lymphoblastic leukemia (ALL) life expectancy through the integration of traditional survival analysis and life expectancy tables.
