Sorry, we haven't been able to create an article by this title, even though it is referred to frequently on the wiki and on House M.D. However, here are some external links that might be of assistance.
Please feel free to create an article here and remove the "external" template. Using text from other non-copyrighted sites is acceptable, but please edit to create a "plain English" site and avoid scientific or medical jargon if you can. In addition, please remember to "wikify" your article to add internal links to the House Wiki.
