What is there to hide?...court refuses to unseal medical records

I heard on the top of the hour news a few minutes ago that among the three motions on behalf of Terri Schiavo's parents that judge George Greer denied was one that would open up Terri Schiavo's medical records with respect to allegations of abuse. Question: Why keep the medical records sealed? Especially in an extraordinary case where a woman's life hangs in the balance? In most allegations of abuse, an investigation ensues, and part of the investigation includes the inspection of medical records. Why the need for privacy for a woman who's brain dead and supposedly doesn't know the difference anyway? If there was not abuse or neglect, the records will reveal as such. What is to be gained by keeping those records sealed?
