Actually, I think that the OP was talking about the treatment of blacks in the profession of medicine. Notice how he/she used the word "restrictions"? I took that to mean restrictions on allowing blacks into the professional community, not racism in medical treatment for black patients. Who knows, maybe I am the one who is wrong, but the first message is a little ambiguous. But I wouldn't say it has "absolutely nothing to do with affirmative action." That isn't clear at all.
I interpreted the thread starter's question the same way you did, but just in case they had a broader construction of racial dynamics in mind, here are a couple of other topics.
There is a really interesting body of literature about the so-called Tuskegee Effect. This derives from the infamous Tuskegee experiment, in which physicians determined to observe the long-term effects of syphilis on the human body ran, in Tuskegee Alabama from the 1930's through the 1960's, a study of a number of syphilis-infected African American men. They treated them for all their other ailments, but never informed them they had syphilis and never treated the syphilis. The "Tuskegee Effect" refers primarily to the difficulty current clinical trials have in recruiting black participants, probably due the mistrust of the medical community. (This also ties in interestingly, but not without complications, to recent findings about the high number of African Americans who believe that the HIV epidemic has been manufactured somehow and targets blacks, the poor, etc.)
Another hot topic that involves race--although this is more a matter of institutionalized racism than one of racist beliefs or actions by individuals--is the lack of access to medical care confronting urban populations as hospitals in cities fail, turn away indigent patients, etc.
