This top-importance health topic was medical collaboration of the week on two occasions and made it to good article in November 2008. It covers the topic comprehensively within the guidelines of WikiProject Medicine and I believe it worthy of being considered for featured status. JFW | T@lk 11:54, 1 March 2009 (UTC)[reply]
