Patient-oriented cancer information on the internet: a comparison of wikipedia and a professionally maintained database.

Purpose: A wiki is a collaborative Web site, such as Wikipedia, that can be freely edited. Because of a wiki's lack of formal editorial control, we hypothesized that the content would be less complete and accurate than that of a professional peer-reviewed Web site. In this study, the coverage, accuracy, and readability of cancer information on Wikipedia were compared with those of the patient-orientated National Cancer Institute's Physician Data Query (PDQ) comprehensive cancer database.

The interventionalism of medicine: interventional radiology, cardiology, and neuroradiology.

Interventional medical practitioners are specialists who do minimally invasive procedures instead of surgery or other treatment. Most often, these procedures utilize various imaging and catheterization techniques in order to diagnose and treat vascular issues in the body. Interventionalist techniques, including injecting arteries with dye, visualizing these via x-ray, and opening up blockages, developed from early pioneers' bold and sometimes controversial experiments which aimed to find safer and better ways to treat coronary artery and other atherosclerotic vascular disease.
