I have had people take hyperbaric oxygen therapy for foot ulcers with some success, but otherwise had no idea these things were being used to treat cancer, AIDS, and other illnesses.  The Cochrane Review looks to be gearing up to review the use of ozone in diabetic foot ulcers soon, stay tuned for some of their usually definitive coverage. 

Doctors purveying questionable therapies: if you're not careful, the FDA will sic the US Marshals on you!

A common irregular and often rapid heart rhythm is known as atrial fibrillation or A Fib. Roughly 2.2 million Americans are suffering from some form of heart rhythm disorder. In atrial fibrillation the heart's two small upper chambers (the atria) vibrate irregularly instead of beating effectively. Blood is also not pumped fully out of them so it may clot more readily. A patient can suffer a stroke if a fragment of clotted blood in the atria leaves the heart and lodges in an artery in the brain. Doctors have known for years about the link between atrial fibrillation and strokes.
