Skepticism is certainly useful, especially in the clinical field, because it avoids unjustified enthusiasm for unproven theories.
Skeptics about the endovascular treatment of MS should probably bother to read the papers published by prof. Zamboni and his team. It seems to me an unlikely coincidence that they found a defective venous drainage from the brain, due to congenital anomalies of the jugular and/or the azygos veins, in 100% of the patients with proven MS. No such anomalies were found in the control group of healthy persons or patients with other neurological conditions. The first man who said that the earth was not flat was put in chains.
I am off to Bologna and I hope that subsequently more people will believe that the earth is a sphere.
I'm not sure which skeptics you mean, people like here at this website or dismissive doctors. You have seen some great immediate results, and I think we are all glad for you. Also, it would indicate this treatment holds promise.
I think you mentioned that you are a doctor, so step back a moment and look at this through your doctor eyes. Dr. Zamboni published a few papers detailing the correlation between the stenosis and MS. So far, no one else has published with the same findings, providing some confirmation. (And, according to reports from members here who have gone to Stanford, Dr. Dake is finding a somewhat different pattern of stenosis. For example, he is finding far fewer stenoses of the azygous). Also, Dr. Zamboni put out one paper describing the first patients that were treated with angioplasty. But no MRIs were done; no criteria for determining who was suffering a relapse was given. Just my opinion, but I think these things add to doctors' skepticism.
Hopefully more details of Dr. Zamboni's work will emerge from the Bologna conference. Here's hoping he finds the New World.
