2011 Clinical Case Studies

Each month, a case and a series of questions can be emailed to interested individuals 4-6 weeks in advance of publication. The published version will include a discussion of the case, important points to remember, and comments from 1-2 experts in the field. We urge you to share and discuss these with your trainees each month.
