The case of John Lykoudis and peptic ulcer disease revisited: Crank or visionary?

One of the themes of SBM has been, since the very beginning, how the paradigm of evidence-based medicine discounts plausibility (or, perhaps more appropriately, implausibility) when evaluating whether or not a given therapy works. One of our favorite examples is homeopathy, a therapy that is so implausible on a strictly scientific basis that, for it to work, huge swaths of well-established science supported by equally huge amounts of experimental and observational evidence would have to be found to be all in serious error. While such an occurrence is not per se impossible, it is incredibly unlikely. Moreover, for scientists actually to start to doubt our understanding of chemistry, biochemistry, pharmacology, and physics to the point of thinking that our understanding of them is in such serious error that homeopathy is a valid description of reality, it would take a lot more than a bunch of low-quality or equivocal studies that show no effect due to homeopathy detectably greater than placebo.

On Friday, Kim Atwood undertook an excellent discussion of this very issue. What really caught my attention, though, was how he educated me about a bit of medical history of which I had been completely unaware. Specifically, Kim discussed the strange case of John Lykoudis, a physician in Greece who may have discovered the etiology of peptic ulcer disease (PUD) due to H. pylori more than a quarter century before Barry Marshall and Robin Warren discovered the bacterial etiology of PUD in 1984. One reason that this story intrigued me is the same reason that it intrigued Kimball. Lykoudis’ story very much resembles that of many quacks, in particular Nicholas Gonzalez, in that he claimed results far better than what medicine could produce at the time, fought relentlessly to try to prove his ideas to the medical authorities in Greece at the time, and ultimately failed to do so. Despite his failure, however, he had a very large and loyal following of patients who fervently believed in his methods. The twist on a familiar story, however, is that Lykoudis may very well have been right and have discovered a real, effective treatment long before his time.

The Water Cure: Another Example of Self Deception and the “Lone Genius”

A correspondent wrote:

I hear all day long on my local radio station commercials for The Water Cure, which was created by a Dr. Batmangelli (I have no idea how to spell his name) promising wonderful cures by eliminating caffeine and alcohol and drinking water and sprinkling sea salt on your food. If you REALLY want to get cured even faster, swim in the ocean everyday.

That’s Dr. Fereydoon Batmanghelidj. His Big Idea was that dehydration is the main cause of disease. It was untenable to begin with, is supported by no evidence, was debunked on Quackwatch several years ago, and Dr. Batmanghelidj died in 2004, so I was surprised to hear it was still being vigorously promoted. But not very surprised. After all, homeopathy is still around.

The Water Cure is another in a long list of alleged miracle cures discovered by “lone geniuses” who are allegedly persecuted by a resistant medical establishment. These stories follow a pattern, and I think it is worthwhile looking at this prime example to understand something of the psychology of self-deception that is involved. (more…)
