Personalized Medicine Bait and Switch

Mark Hyman, a proponent of so-called “functional medicine” promoting himself over at the Huffington Post (an online news source that essentially allows dubious medical infomercials to pass as news) has posted a particularly egregious article on personalized medicine for dementia. In the article Hyman distorts the modern practice of medicine, the current state of genetic science, and the very notion of “disease.” It is, as usual, a fine piece of medical propaganda sure to confuse many a reader.

Hyman starts with some standard epidemiology of dementia – it is a common and growing disorder – but then descends quickly into distortion and pseudoscience.

Conventional Medicine Strawman.

Hyman creates what readers are likely to recognize by now as the standard straw man of conventional or science-based medicine, and then uses that caricature to create a false dichotomy with his “functional” medicine. He writes:

Bioidentical Hormones

The Medical Letter recently evaluated “bioidentical” hormones and concluded

There is no acceptable evidence that “bioidentical” hormones are safe or effective. Patients should be discouraged from taking them.

“Bioidenticals” include progesterone, estrogens (estriol, estradiol, and estrone), and testosterone. They have mainly been promoted as a safer, more natural alternative to menopausal hormone replacement therapy (HRT), but they are also claimed to increase energy, well-being, and quality of life, and to have an anti-aging effect. Suzanne Somers recommends them for all age groups and both sexes. There is no evidence to support any of those claims.

The whole “bioidentical” thing is a pseudoscientific concept: it is a marketing term rather than a scientifically meaningful one. Bioidenticals are promoted by celebrities like Suzanne Somers, a few maverick medical doctors like Kent Holtorf, proponents of “natural” medicine, patients who were frightened by the Women’s Health Initiative study of hormone replacement therapy, and critics of Big Pharma. The mainstream scientific community is in consensus: a number of medical organizations, from the American Cancer Society to the Mayo Clinic, have issued statements similar to that of The Medical Letter.

The price of opposing medical pseudoscience

EDITOR’S NOTE: This post is a followup to a post from two weeks ago entitled In which Dr. Gorski once again finds himself a target of the “pharma shill” gambit. If you haven’t read that post before, you might want to go back and read it now before proceeding with this post. Please also note the disclaimer.

I want to beg your indulgence this week, hoping that my history as a blogger here on SBM and then as managing editor allows me that. Today’s post will be a little different because last week was really, really, hectic. First and foremost, I was busy writing a preapplication for a Susan J. Komen Foundation grant for a deadline of last Friday. The Komen Foundation, it turns out, has changed its procedures this year so that the preapplication is now evaluated much more rigorously. It’s no longer looked at just to make sure that the proposed project matches the subject matter and criteria for the request for applications (RFA). This year, the preapplication actually matters! Moreover, it’s so long that writing it is practically like writing the entire grant, other than the budget. But I got it done, and it looks pretty good, if I do say so myself. None of that is any guarantee that Komen will invite us to submit a full application, but I’m hopeful because if it does we should have a good shot at the grant.

Then, this weekend I had to pivot on a dime and return to writing the R01 I had been working on with my collaborator. To make the July resubmission deadline, it has to be done, in the can, and submitted by this Friday. In any case, these are the reasons why this post is likely to be uncharacteristically personal in nature.

Oh, those reasons plus a little bit of character assassination launched at me on Monday by Jake Crosby over at the Age of Autism, entitled David Gorski’s Financial Pharma Ties: What He Didn’t Tell You.

Professional Integrity for Sale? “Sure,” Says Medscape!

Some chiropractors also practice homeopathy. According to Frank King, D.C., many more should be doing just that:

Homeopathy is an energetic form of natural medicine that corrects nerve interferences, absent nerve reflexes, and pathological nerve response patterns that the chiropractic adjustment alone does not correct. The appropriate homeopathic remedies will eliminate aberrant nerve reflexes and pathological nerve responses which cause recurrent subluxation complexes.

Not only does homeopathy correct nerve interferences, it empowers the doctor of chiropractic to reach the entire nervous system. What this means is that we can now better affect the whole person, and all of the maladies that affect us. Homeopathy’s energetic approach reaches deep within the nervous system, correcting nerve interferences where the hands of chiropractic alone cannot reach. Homeopathy is the missing link that enables the chiropractor to truly affect the whole nervous system!

But that’s not all:

The FDA for the Average SBM Consumer

How the Food and Drug Administration came to be is a story that is filled with death, intrigue and dubious characters. It also, like most stories, has its share of heroes and vindications. The list of those who have died to bring us the agency we know today is long, but even today, the death-toll continues. Now this is not the horrible thing it may at first seem. People are all born with a terminal disease known as life, and they will die. The goal of Medicine is to forestall that death as long as possible and to give people good, long, healthy and safe lives. This is where the Food and Drug Administration comes into play. They help guide the pharmaceutical world in the safest manner possible.

The legal quagmire that is the Food and Drug Administration (FDA) is a result of a series of laws which it behooves the Science-Based Medical community, to understand. Many of these laws were a result of deaths, which were themselves the result of either poor safeguards, or, as we will see in one case, lack of information on the part of a company. It began with the Division of Chemistry inside the U.S. Department of Agriculture. The original concern of this group was the misbranding and adulteration of both food and drugs. The first of the laws which came into effect, to give the Bureau of Chemistry as it became known, was the Biologics Control Act of 1902. As is so often the case with FDA regulations, this was a result of deaths in the populous.

Cracking Down on Stem Cell Tourism

The International Society for Stem Cell Research (ISSCR) is a professional organization of stem cell researchers. I am happy to see that they see it as their responsibility to respond to the growth of dubious stem cell clinics offering unproven treatments to desperate patients.

In a recently published handbook for patients, they write:

The International Society for Stem Cell Research (ISSCR) is very concerned that stem cell therapies are being sold around the world before they have been proven safe and effective.
Stem cell therapies are nearly all new and experimental. In these early stages, they may not work, and there may be downsides. Make sure you understand what to look out for before considering a stem cell therapy.
Remember, most medical discoveries are based on years of research performed at universities and companies. There is a long process that shows first in laboratory studies and then in clinical research that something is safe and will work. Like a new drug, stem cell therapies must be assessed and meet certain standards before receiving approval from national regulatory bodies to be used to treat people.

This is good advice for any new treatment.

Defending Isagenix: A Case Study in Flawed Thinking

The Internet is a wonderful new medium for communicating ideas and information in a rapid and interactive way. Many articles are followed by a “comments” section. Like so many things in this imperfect world, comments are a mixed blessing. They can enhance the article by correcting errors, adding further information, and contributing useful thoughts to a productive discussion. But all too often they consist of emotional outbursts, unwarranted personal attacks on the author, logical fallacies, and misinformation. They provide irrational and ignorant people with a soapbox for promoting prejudices and false information.

To illustrate, let’s look at the responses to something I wrote about a weight loss product called Isagenix that is sold through a multilevel marketing scheme. To quote the website,

The Isagenix cleanse is unique because it not only removes impurities at the cellular level, it builds the body up with incredible nutrition. Besides detoxing the body, Isagenix teaches people a wonderful lesson that they don’t need to eat as much as they are accustom to and eating healthy choices are really important and also a lot of the food we are eating is nutritionally bankrupt. [errors are in the original]

I didn’t set out to write an article about this. It started when I received an e-mail inquiry about Isagenix. I posted my answer on a discussion list and it was picked up and published on the healthfraudoz website.  Sandy Szwarc approved of it and kindly reposted it on her Junkfood Science blog

As I write, the comments on the healthfraudoz website have reached a total of 176. A few commenters approved of what I wrote, but the majority of commenters tried to defend Isagenix. Their arguments were irrational, incompetent, and sometimes amusing. (more…)

Cancer Treatment Centers of America and “naturopathic oncology”

EDITOR’S NOTICE: NOTE THE DISCLAIMER.

On “wholistic” medicine

If there’s one aspect of so-called “alternative medicine” and “complementary and alternative medicine” (CAM) is that its practitioners tout as being a huge advantage over what they often refer to sneeringly as “conventional” or “scientific” medicine is that — or so its practitioners claim — alt-med treats the “whole patient,” that it’s “wholistic” in a way that the evil reductionist “Western” science-based medicine can’t be. Supposedly, we reductionistic, unimaginative physicians only focus on disease and ignore the “whole patient.” Of course, to me this claim is belied by the hectoring to which my own primary care physician has subjected me about my horrible diet and lack of exercise on pretty much every visit I’ve had with her, but then maybe she’s an anomaly, along with Dr. Lipson on this very blog and pretty much every other primary care doctor I’ve ever dealt with. Anecdotal experience, I know, but since alt-med mavens appear to value anecdotal evidence above pretty much all else I thought it appropriate to mention here. Also belying the claim of alt-med practitioners that they “individualize” treatments to their patients in a way that science-based medicine does not is the maddening tendency of various alt-med modalities to settle on just One True Cause of All Disease, be it liver flukes as the One True Cause of Cancer, heavy metal toxicity as the One True Cause of cancer, autism, and various other diseases, or “allergies,” acid, or obstruction of the flow of qi as the One True Cause of All Disease.

Given the claim of “wholism” that is such an advertising gimmick among many of the varieties of woo, I’m always interested when I see evidence that alt-med is imitating its envied and disliked reductionistic competition. True, this is nothing new, given how alt-med has tried to seek legitimacy by taking on the mantle of science-based medicine wherever it can. Examples include the National Center for Complementary and Alternative Medicine (NCCAM), various organizations that try to confer legitimacy to pseudoscience by providing “certification” in various flavors of woo, and moves to push state medical boards to go further than that and confer legally protected status to practitioners by actually licensing them. This latter tactic has been very successful in that many states now license acupuncturists, while some states even license naturopaths and “homeopathic physicians,” the latter of which I find quite amusing because the term perfectly encapsulates what must remain of such a physician’s medical training after being diluted to 30C with woo. The only difference is that, unlike what is claimed with homeopathy, diluting MD medical knowledge with woo does not make it stronger. In terms of naturopathy, though, one of the most alarming aspects of the infiltration of naturopaths into the health care system is that some states in the U.S. and provinces in Canada are seriously considering allowing them to prescribe real pharmaceutical medications, even though they lack the training and knowledge to use such drugs safely.

Imagine my combination of bemusement and alarm, then, when I learned of a new specialty of pseudoscience, namely the field of naturopathic oncology.

Be afraid. Be very afraid. (I know I was when I first encountered this specialty.)

Medical Voices: Always in Error, Never in Doubt

I have discussed two articles from the web site Medical Voices, one with 9 questions, the other on mumps. There are, I think, 18 web pages of articles about vaccines on that web site. I am uncertain as to the true number of pages of information as the navigation buttons at the bottom of the pages do not always seem to function correctly. That such a problem exists suggests that no one has bothered, like me, to go through the web site to read all the essays. Or maybe it is me and the price of using the Chrome browser. Anyway, there are a large collection of essays that serves as a rich vein of iron pyrite to mine for topics. At about 5 entries to a page, evaluating at a pace of about one monthly, it would take years to analyze all the misinformation on Medical Voices.

It occurs to me that at the center of each article is a nut of misinformation (or sometimes as many as nine) that serves as the core fallacy of that article. I want to emphasize that I am using ‘nut’ as a metaphor for seed, not in its other, more colloquial, meaning. So rather than an in-depth evaluation of each article (although some will warrant a future, more through review), I thought it would be interesting to identify the nut in each article and why it is wrong. So, in the spirit, but not the intellectual rigor, of Generation Rescue‘s “14 Studies“, let’s sort through the nuts …
