It’s Thanksgiving in the U.S., one of my favorite holidays. Thanksgiving habits get set down early in life, and the while I may find your lima bean casserole execrable, to you it’s just not Thanksgiving without it.
And speaking of excrement, you can expect to see adds encouraging you to “detox” from all of your holiday excesses. Outside the field of substance abuse, what the hell is “detox” anyway? “Detoxification” is apparently the pinnacle of modern health care, if you believe the dozens of adds on late-night TV.
For me to explain to you why even the very idea is laughable, I have to teach you a bit of human biochemistry—just a little, I promise. My scientific readers will find this grossly oversimplified, but hopefully they will forgive me.
Detox sounds so simple, but in fact, human biology is more complex and beautiful than is dreamt of in the quacks’ philosophies. (more…)
Many Americans will be introducing more food than usual to their GI tracts on this Thanksgiving Day, and so I thought I’d provide you with a special gastroenterology-related post to complement the mood. If you have already eaten, I might suggest that you come back to this post on an empty stomach. I will be discussing the alternative medicine practice known as “fecal transplantation” and it is rather unsavory.
The idea of transferring stool from one person to another (for the treatment of various GI disorders) was first described in the 1950s. This month the TV show, Grey’s Anatomy, featured the practice in one of their plot lines – which rekindled interest in the therapy, and resulted in an explosion of search engine activity. I figured it was probably my duty, as a member of Science Based Medicine, to offer a rational analysis of the treatment in the hope that the Google gods will serve up my post to a few of the information-seekers out there. I hope to reach them before the snake oil salesmen, wrapped in their mantle of “gentle, natural cures,” convince them that they desperately need a good colon or liver cleanse, if not a fecal transplant.
Like most alternative therapies, fecal transplantation is based on a drop of truth and a gallon of pseudoscience. It is true that the gastrointestinal tract is teeming with hundreds of thousands of bacterial species and pseudo-species, and that without them we would die. It is also true that certain nasty bugs (like clostridium difficile) cause problems when they take up residence within the gut. Antibiotics do upset intestinal flora, much to the consternation of infectious disease specialists. Now, all that being said – the practice of repopulating the gut with another person’s stool requires some fairly grand assumptions about efficacy and safety that are not founded upon any clinical trial data whatsoever.

Pat Wagner (or “The Bee Lady,” as she likes to be called) treats herself for multiple sclerosis (MS) by allowing bees to sting her. She calls this bee-venom therapy (BVT) and believes it has saved her from MS.
There are now thousands of people who administer BVT to themselves or others, mostly in private homes by unlicensed practitioners. BVT is not prescribed by a doctor, yet it is used like any other drug, given in regular doses at regular intervals. There is no scientific evidence to support its use, and yet thousands of multiple sclerosis sufferers and others tout its effectiveness.
BVT, which is one modality within Apitherapy, or the use of various bee products as a medical treatment, is still a relatively small phenomenon. It is largely an unrecognized grassroots or folk medicine treatment – but like all such phenomena has been given a huge boost recently by the easy spread of information via the internet. It has also been adopted by many so-called alternative medicine (CAM) practitioners, and has been increasingly wrapped in the typical marketing jargon of CAM. So, in a way, this grassroots treatment has been corporatized by the CAM industry.
One-fourth of the veterans of the 1990-91 Gulf War complain of persistent memory and concentration problems, chronic headaches, widespread pain, gastrointestinal problems, and other chronic abnormalities not explained by well-established diagnoses. Treatments are ineffective and symptoms do not improve over time. Gulf War Syndrome or Gulf War Illness is a controversial diagnosis, and some have questioned whether it really exists. Now a new report from the Research Advisory Committee on Gulf War Veterans’ Illnesses has concluded that Gulf War Illness is real and that it is probably attributable to pyridostigmine bromide (PB) and pesticide exposures.
Its major conclusions:
Gulf War illness is a serious condition that affects at least one fourth of the 697,000 U.S. veterans who served in the 1990-1991 Gulf War.
Gulf War illness fundamentally differs from trauma and stress-related syndromes described after other wars.
Evidence strongly and consistently indicates that two Gulf War neurotoxic exposures are causally associated with Gulf War illness: 1) use of pyridostigmine bromide (PB) pills, given to protect troops from effects of nerve agents, and 2) pesticide use during deployment.
The Research Advisory Committee on Gulf War Veterans’ Illnesses was mandated by Congress and appointed in 2002. The report, published November 17, 2008, is an exhaustive review of all available data, including some that is unpublished. It runs to 454 pages, has multiple authors and consultants, lists 1840 references and has multiple appendices. I can’t pretend to have mastered all the information, but I have read enough to understand the basis of their conclusions. They are based on good evidence and logic, but they leave me with some doubts. (more…)
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 JAMA and I came across a study funded by the agency. The study, which showed that Ginkgo does not prevent Alzheimer’s-type dementia, was pretty good, so I cruised on over to NCCAM’s website to see what else they’ve been up to.
A quick glance at NCCAM’s front page:
“Ginkgo Evaluation of Memory (GEM) Study Fails To Show Benefit in Preventing Dementia in the Elderly”“CAM and Hepatitis C: A Focus on Herbal Supplements ‘No CAM treatment has yet been proven effective for treating hepatitis C or its complications.’”“Selenium and Vitamin E in Prostate Cancer Prevention Study, ‘selenium and vitamin E supplements, taken either alone or together, did not prevent prostate cancer.’”
CAM is a group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine. Conventional medicine is medicine as practiced by holders of M.D. (medical doctor) or D.O. (doctor of osteopathy) degrees and by their allied health professionals, such as physical therapists, psychologists, and registered nurses. Some health care providers practice both CAM and conventional medicine. While some scientific evidence exists regarding some CAM therapies, for most there are key questions that are yet to be answered through well-designed scientific studies–questions such as whether these therapies are safe and whether they work for the diseases or medical conditions for which they are used.
The list of what is considered to be CAM changes continually, as those therapies that are proven to be safe and effective become adopted into conventional health care and as new approaches to health care emerge. emphasis mine, ed.
Although this blog is about medicine, specifically the scientific basis of medicine and threats to the scientific basis of medicine regardless of the source, several of us also have an interest in other forms of pseudoscience and threats to other branches of science. One branch of science that is, not surprisingly, critical to medicine is the science of biology, and the organizing theory of biology is the theory of evolution, which was first reported by Charles Darwin and subsequently synthesized with the developing science of genetics in the early 20th century and then with our increasing knowledge of molecular biology, genomics, and proteonomics whose rise ushered us into the 21st century. However, the implications of evolution, namely that humans and apes both evolved from a common ancestor and that humans, for all their belief of being different and superior to animals, are in fact related to animals in the great chain of life going all the way back to single-celled organisms, does not go down well with certain religious fundamentalists, particularly Christian fundamentalists. Whereas I (and I daresay several of my cobloggers) find the interconnectedness of life, including humans, implied by Darwin’s theory to be beautiful and uplifting, many fundamentalists see it as a profound threat to their world view. Consequently, they have attacked the theory of evolution at every turn and tried to insert creationism, particularly the latest incarnation of creationism known as “intelligent design,” into science classes as an “alternative” to “Darwinism.” The manner in which they torture science, logic, and reason to try to cast doubt on a theory that is every bit as rock solid in terms of massive quantities of experimental and observational evidence to support it as any other theory in science, if not more so, is legendary and well documented at blogs such as The Panda’s Thumb and websites such as Talk Origins.
Although one day I plan on writing about how insights from evolutionary theory have led to deeper understandings of human disease and strategies to improve human health in the future, this time I want to concentrate on the similarities in techniques of spreading disinformation between creationists and purveyors of unscientific medical “treatments.” For background, first, you need to be aware of a movie that was released in April. The movie, Expelled!: No Intelligence Allowed was released. Starring Ben Stein at his most unctuous sporting a bullhorn and styling himself as a conservative, buttoned-down version of Angus Young through his choice of apparel in its promotional material, the movie’s main theme is that any academic who “questioned Darwinism” is “expelled” from academia. The basic idea is that “intelligent design” creationism is being “suppressed” by biologists who just can’t accept the thought of the existence of a “designer” (i.e., God). Indeed, the movie goes so far as to equate biologists and scientists who accept the theory of evolution as the best current explanation for the diversity of life to Hitler and the Nazis and their “suppression” of “alternatives” (word choice intentional) to “Darwinism” to Nazi and Stalinist persecution of dissidents and perceived threats to the regime. The movie even features a sequence where Ben Stein visits Dachau and Auschwitz, as though to imply that biologists are busy firing up the ovens for the Brave Maverick Scientists who “dissent from Darwin.”
These Brave Maverick Scientists are a lot like the Brave Maverick Doctors who champion unscientific medicine. After all, Kevin Trudeau has made a cottage industry and sold millions of books based on the claim that there are “natural cures” that “they” (as in doctors, pharmaceutical companies, and the government) don’t want you to know about and that as a consequence the full forces of these groups are being marshalled to “suppress” them and “persecute” the Brave Maverick Doctors who dare to question the “orthodoxy” of “allopathic medicine,” up to and including claims of “Nazi”-like suppression. (Just read those repositories of quackery NaturalNews.com and Whale.to if you don’t believe me.) For the “alternative medicine” movement, it’s all there, in websites, blogs, and books. But one thing that the movement pushing unscientific treatments has lacked, and that’s a movie to call its own, a movie to spread the same message.
A baby’s body is bombarded with immunologic challenges—from bacteria in food to the dust they breathe. Compared to what they typically encounter and manage during the day, vaccines are literally a drop in the ocean”, and Dr. Offits studies theoretically show an infant could handle up to 100,000 vaccines at one time … safely (6).
It is not the mercury in vaccines, its the vaccine schedule that is the problem. Too many shots, too many antigens, too close together. Our children need to be exposed to fewer antigens, less often, so they don’t get complications from the vaccine like autism and autoimmune diseases. It is all part of greening our vaccines.
That is part of propaganda on vaccines from the More Infectious Diseases for Children, a.k.a. antivaccine groups.
What is the vaccine schedule? How much exposure do children receive from organisms and antigens as part of the vaccination schedule? The entire schedule is at CDC.
In summary there are 5 live attenuated or altered organisms and 21 different antigens by age 6. A couple of vaccines are added from age 7 to 18, but by then it is too late, your child already has autism and autoimmune diseases from the immunologic and toxic scourging of vaccines. BTW. Sarcasm.
Is the vaccine schedule a lot of virus and a lot of antigens? Is this an enormous load on the immune system, sending it spiraling out of control to damage the child? Lets find out. (more…)
There is something unexpectedly sinister about this news report from my former home town in Canada. Apparently, a local chiropractor has been using his “medical training” to excuse his sexual misconduct. Here’s the story from the Halifax Chronicle Herald:
During a hearing in July, the woman said the chiropractor would frequently grip her around the ribs and hold tight, sometimes cupping her breasts, while speaking softly over her shoulder.
On other visits, she said, he would have her lie on a table and would undo one side of her johnny shirt, exposing her breast, place a thumb between her breasts and roll her onto her side by pressing the weight of his own body on her.
Dr. LaPierre testified he performed a technique called the Zindler manoeuvre. It involves applying precise, quick pressure to a restricted joint to restore movement. He said he would have explained the procedure to her the first time but not on subsequent treatments…
The second incident involved a woman who complained that in 2006 the chiropractor “massaged” her breast while trying to find the source of her back pain.
Dr. LaPierre said he was using a technique called “matrix repatterning” that required contact with the woman’s sternum. He said he didn’t recall where the rest of his hand was at the time. He determined the woman had a rib out of alignment.
What was the punishment for his behavior?
Dr. Phillip LaPierre must have a female observer present when he examines women for the next five years, must take training on interpersonal skills and must pay a fine and costs totaling $26,000 now that a panel of the Nova Scotia College of Chiropractors has found him guilty of sexual misconduct based on the two complaints.
It’s hard to imagine such a small fee in an American court of law. If a US physician were molesting his patients, I’m willing to bet that the fine would have an additional zero or two at the end. (more…)
Freedom is a cherished commodity in our culture, as it should be. Our laws are largely based upon the premise that individuals should have the liberty to do what they want, unless there is a compelling public or governmental concern that overrides such liberties.
It is therefore no surprise that freedom is a common marketing theme – selling the idea of individuality or personal freedom of choice.
The marketers of dubious, unscientific, or fraudulent health care products and services are savvy to the marketing theme of freedom and have used it to great effect. It is all ultimately, however, a deception. There is an ulterior motive that has nothing to do with the freedoms of the public but rather is an end run around regulations meant to protect the public.
AllergiCare Relief Centers are a chain of franchises started by a man called David Tucker who is not listed as having an MD or any other title. They offer diagnosis of allergies by biofeedback and treatment of allergies by laser acupuncture. They admit that the method is not backed by any science, and they claim that what they are doing is not medical treatment.
Responsible journalism might have investigated this as quackery or practicing medicine without a license. Instead, irresponsible journalism has helped promote these centers and has given them invaluable free advertising.
Tucker said the device works based on biofeedback. The allergy sufferer wears a sensing clip on his finger for testing, and the computer simulates the bio-frequency for 10,000 known allergens. As the body responds to those stimuli, the computer lists which substances are irritants. “This digitized allergen actually matches the harmonic frequency of the actual allergen, making the body believe it is in contact with the real substance,” Tucker said. “The body will react if it is allergic to the particular substance.” ….Once the allergens are identified, a laser stimulates biomeridian points on the body — the same points used in acupuncture and acupressure. Tucker said the idea is to strengthen organs to act properly the next time they encounter the allergen — that is, to treat them as harmless…So far, there is no science to prove the devices work, but Tucker claims a 70 percent positive response rate.
