Cuba was my second thought (immediately after India), before I heard of Simka, etc. I did some cursory research, and came up only with Mr. Markley - who wanted money to reveal the contacts. I love olive oil, but not oily characters. I cannot say what he his, but I didn't have a good feeling.
Cuba does have a first-rate medical system. I do not think that the lack of blog entries has much to do with censorship - if I went to Cuba and had treatment, I could not be censored. Further, the Cuban Ministry of Health would likely be glad to advertise and attract "hard currency".
Try Dr. Sinan in Kuwait. He is over-seeing treatments in Bahrain and Egypt. http://www.ccsvikuwait.com

You should be able to find something on Google about who you intend to deal with, and if not... You should be able to have some kind of contact with the doctor, or facility, before putting money down - in my view. Be careful. Ask for patient references, and check them out.
