Utility of Abdominal Cross-Sectional Imaging in Motor Vehicle Accidents in an Inner City Trauma Center: A Retrospective Cohort Study.

Background The use of computed tomography (CT) of the abdomen and pelvis following motor vehicle collisions (MVCs) as standard diagnostic evaluation is widely accepted. However, the incidence of positive findings is low, and it is unknown which features increase the risk of having abdominal injuries. Objectives The aim of this study is to identify risk factors on presentation that are associated with positive CT findings.

Systemic amyloidosis causing intestinal hemorrhage and pseudo-obstruction.

There are two major forms of amyloidosis, primary amyloidosis (AL) and secondary amyloidosis. AL amyloidosis results from deposition of immunoglobulin light chains or their fragments. One such example is AL amyloidosis associated with multiple myeloma, in which overproduced immunoglobulin light chains get deposited onto tissues, leading to tissue dysfunction.
