The P&S Medical Review (ISSN 1074-1585) is a peer-reviewed journal founded and edited by the students of the Columbia University College of Physicians and Surgeons (P&S). It is intended to be a scientific and medical journal containing review articles and original research completed by members of the extended Columbia community, with a particular emphasis on student-authored work. It seeks to address topics of clinical concern, though basic science articles are also accepted for publication. Also welcomed are case reports and correspondences relating to current medical controversy.

Editors are enrolled P&S students who produce the publication under the guidance of a board of faculty advisors drawn from the departments of the College of Physicians and Surgeons of Columbia University. All articles are subject to rigorous, anonymous peer review prior to acceptance for publication; peer reviewers are chosen from the Columbia community when possible. Instructions for authors can be found on the last page of the journal.

The P&S Medical Review is distributed free of charge to all P&S medical students and house officers of departments that support us through departmental subscriptions. Individual subscriptions are also available. For subscription information contact us at the address given in the Instructions for Authors, or by e-mail at psmedrev@columbia.edu. The P&S Medical Review is available in electronic media on the World Wide Web at http://cpmcnet.columbia.edu/news/review/.
