Study of Cushings/Pseudo

Recommended Posts

This is up at OHSU.  You can call Dr. Samuels directly and inquire about the study.  You may need to have an ACTH test run by your doctor, but otherwise I wouldn't be surprised if you qualify.  The best part is that if they prove you have Cushings then you can have the surgery there.  Actually, the vest best part is that it's all FREE since you're in a study.  I've seen Dr. Samuels and she's an excellent doctor, answers her phone, is caring, etc.  Enough from me, here's the details:
