Health information is also protected but you don't see that stopping every college and pro team from discussing an individual's injury and surgical procedures, drug tests, and alcohol encounters. Like others have said, it is the way the world works. Also, like others, if it is true about what is leaked, I could care less about how it makes him look. He knew going into this that he, as an athlete, is under a microscope and that everything he does is going to be discussed and he still decided to do what he did.
HIPPA (the patient privacy and protection act of which this is only one part of of HIPPA and something I know quite a bit about working in the healthcare industry) provides several methods that would allow a college or university to discuss an athletes medical issues from any perspective. The university can ask an athlete for a blanket right to release information regarding the atheltes medical conditions and / or testing results. Many colleges and universities ask for this release due to the blanket terms under which HIPPA is governed and the penalties for violation being so stiff per incident. Also the college could ask for a release to discuss specific tests or medical procedures. There are implementations in the rules that cover almost ever which way medical data can be released and I will bet that many colleges and universities request that kind of release from an athelete since they are so visible in the community and area.
