Cansado,
You might not be aware that several doctors in Belgium who are trying to treat CFS in ways outside the national health care standard have had actions taken against them akin to what happened to Dr. Myhill in the UK. I am too tired to look it up, but there are articles related to that available.
It can also be harsh for doctors in the US to specialize in CFS, as it is pretty much anathema in the medical community, and almost a guarantee you will not get funding if you are a researcher. We also have "standard of care" guidelines, and rules about "experimental" treatments, which can be enforced at any time should whatever regulating agency get a wild hair.
I can fully understand why doctors would want privacy on this matter.
It's tough for us, because we all desperately need an open forum of information exchange.
After all, when patients post, they often post with a login name for themselves, but disclose all kinds of info about their doctor. While it is extremely helpful for us to know the maximum of what is happening treatment-wise from each other, I can see how a doctor would not want to risk his or her own career, or ability to continue practicing, due to indiscriminate public chat from patients.
Maybe we should consider some kind of fancy encryption code for doctors and treatments!
