Natural versus “natural” in CAMworld

“When I use a word,” Humpty Dumpty said in rather a scornful tone, “it means just what I choose it to mean — neither more nor less.” “The question is,” said Alice, “whether you can make words mean so many different things.” “The question is,” said Humpty Dumpty, “which is to be master— that’s all.” From: Through the Looking Glass, and What...

Our own slippery grounds

When we were forming the National Council against Health Fraud I wondered aloud to the president, Bill Jarvis, what we would do if society solved the chiropractic problem. Bill laughed and said there would never be an end to quackery claims. How right he was. But why? Many express surprise that at this time of remarkable intellectual and scientific advance, so many...

Psychological support and breast cancer – again

Does the degree of efficacy is depend on the time at which it is measured? Apparently so. The case of psychological support and breast cancer longevity again. After an original 1989 report of positive effects on metastatic breast cancer, by 2006- 7 the majority of RCTs on such effects had settled the issue in the negative. This was only after 20 years...

Do over one in five breast cancers detected by mammography alone really spontaneously regress?

It figures. Last Wednesday, right before the four-day Thanksgiving holiday weekend, as I was far more interested in preparing to have family over the next day than in what was going on in the medical news or the blogs, the results of a most fascinating study hit the news. In Medscape, the title of the news report was Mammography Study Suggests Some...

The “Gonzalez Trial” for Pancreatic Cancer: Outcome Revealed

A Review Dr. Lipson’s “detoxification” post on Thanksgiving Day and Dr. Gorski’s recent post about “Gerson Therapy” were timely, because last weekend I noticed something that I should have noticed months ago. Before delivering the punch line, let me remind you, Dear Reader, of the nature of the topic. The regimen advocated by Nicholas Gonzalez is a variation of a “detoxification” treatment for cancer that has...

NCCAM: the not-even-wrong agency

The National Center for Complementary and Alternative Medicine (NCCAM) is a government agency tasked with (among other things), “[exploring] complementary and alternative healing practices in the context of rigorous science.” In this space we have talked about NCCAM quite a bit, but I have to admit that I don’t think about them very much. The other day, though, I was reading though...

On the dangers of using valid placebo controls in clinical trials of acupuncture

I don’t recall if I’ve ever mentioned this before on this blog, but there was a time when I was less skeptical of acupuncture than I am now. It’s true. Don’t get me wrong, though. I never for a minute considered that the whole rigamarole about “unblocking” or “redirecting” the flow of that mystical life force known as qi had anything to...

Vitamin Cocktail with a Meme Twist (Supplement my gimlet with a dash of dissonance)

A trail of recent reports is trying to tell us something. But are we listening, and are “they” listening? If so, does it mean the same to “them” as it does to us? The report trail is telling us that multiple vitamins fail as preventatives against cardiovascular disease, cancer, or even for anything other than for dietary vitamin deficiency. And that is...

Statins Are Better on JUPITER

Over 26 million Americans are taking statin drugs. Some people think they should be available over-the-counter without a prescription, and it has even been facetiously suggested that they should be added to our drinking water. The protective effect of statins in cardiovascular disease and in high-risk patients with high cholesterol levels is well established. But what about people with no heart disease...

When Further Research Is NOT Warranted: The “Wisdom of Crowds” Fallacy

Most scientific research studies have at least one thing in common: the conclusion section ends with, “further research is warranted.” I’d say it’s about as common as the “talk to your doctor” disclaimer in TV ads for pharmaceutical products. And in a way, they both serve the same purpose. They’re a “CYA” move. What does “further research is warranted” mean in plain...
