A CDA Oasis Case Conferences is a two-part presentation of a clinical case. In Part 1, we invite you to watch the short video of the case and provide comments about a possible diagnosis and treatment. You will also have the opportunity of submitting any questions you might have related to the case*. In Part 2, the case presenter shows how the case was managed and answers key questions.  

* When you submit comments and questions in conjunction with Part 1 of the case conference, they do not go live on the Oasis Discussions website. They are received and moderated by the Oasis Team . Summaries of the comments are compiled and posted in the second part of the case presentation and key questions will be forwarded to the clinical presenter for consideration.
