A few weeks ago I posted an article about bogus diagnostic tests. I cited Doctor’s Data, Inc. (DDI), as “a company with a long history of dubious offerings.” I also wrote:
You can’t help but have noticed that many of the links in this post are to articles on Quackwatch. That’s because the site is chock full of useful information about bogus tests, far more than can be found elsewhere. There you will find a more comprehensive list of bogus tests than I’ve mentioned here, and a larger list of laboratories peddling them. You’ll also find an article on “Dubious Genetic Testing” co-authored by the Quackwatch founder, Stephen Barrett, and our own Harriet Hall, and an article about bogus “biomedical treatments” for autism showing that—surprise!—Doctor’s Data and Genova Diagnostics are major players there, too.
I stand by all of those statements. It turns out that Doctor’s Data is not pleased that Dr. Barrett has so thoroughly blown the company’s cover.
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:
Carlyle said “a lie cannot live.” It shows that he did not know how to tell them.

There is an infamous hoax from last century called The Protocols of the (Learned) Elders of Zion, an anti-Semitic text purporting to describe a plan to achieve global domination by the Jewish people. Despite the fact that the Protocols is a work of fiction, there have been and still are folks who believe it to be real, from Hitler on down. (Or is that “on up”? Can one be lower than Hitler? And have I already committed a breach of Godwin’s Law?)
Inventing apparently legitimate information is a useful propaganda device not limited to anti-Semites. Having people appear evil or uncaring using their own words is far more effective than calling them evil and uncaring.
There are many in the community who suffer from a variety of complaints that I cannot diagnose, and, as people do not like uncertainty about their health, they will find someone who will give them a diagnosis. Not infrequently they will come upon the idea of chronic Lyme disease.
The road from an idea to a useful drug is a long one, and in cancer it is often particularly long. One reason is that to be able to tell whether a given treatment is effective against cancer often takes several years at a minimum, in order to determine if patients receiving the new treatment are surviving their disease longer than those who are not. Surrogate endpoints are usually not enough. Tumor shrinkage in response to a drug often does not correlate with prolongation of survival, although the converse (i.e., lack of tumor shrinkage in response to a new drug) does strongly correlate with failure of a treatment to prolong survival. In other words, effects observed on surrogate endpoints are not enough to judge whether a cancer therapy is working or not.
Three years ago, predating the existence of this blog by nearly a year, I became aware of a story that involved many of the issues in bringing a compound from the laboratory to the clinic. The case was unusual in that is is very rare to see the scientific process by which new drugs progress through the stages of cancer research, from concept to testing in cell culture to testing in animals to testing in humans challenged so strongly by patients themselves. The reason that this normally doesn’t occur is that new cancer treatments are almost always the product of either university-conducted research, pharmaceutical company-conducted research, or partnerships between the two. This case was markedly different in that it involved a chemical that was not only easy to synthesize, but cheap and long out of patent. Even more intriguing, it targeted a metabolic abnormality found in many cancer cells, an abnormality first described nearly 80 years before by Otto Warburg in 1928. This latter aspect of the drug gave it every appearance of a “rediscovery” of old wisdom that big pharma had ignored for 80 years, and that only added to its mystique.
The chemical was dichloroacetate (DCA), and three years ago it created a world-wide sensation. Last week, it created a sensation again, as breathless news reports once again overhyped its promise. Since I’ve been following the story since early 2007, I appear to be in as good a position as anyone to tell the story thus far and put the new findings into context. To begin that process, let’s head back to January 2007.
A few years ago a friend asked me to comment on advice given to her adult daughter by a psychiatrist whom she’d consulted for depression. The psychiatrist had recommended testing samples of saliva and urine for hormone and neurotransmitter levels, the results of which would likely indicate a need for supplements to correct deficiencies or imbalances. According to the psychiatrist, who had an academic appointment at a medical school in New York City, “I have been using these supplements with a great deal of success.” My friend is not medically or scientifically sophisticated, but this made her a little uncomfortable. In that, she was entirely justified.
During our recent panel discussion at the NECSS, a member of the audience identified himself as a clinical pathologist at a major medical center, and wondered what he might do to become involved in the good fight against encroaching pseudoscience in medical schools. Clinical pathology is the medical specialty that concerns itself, in summary, with laboratory tests—their development, their validity, their interpretation, their usefulness and, by implication, their misuse. A topic that we haven’t much featured on SBM (we touched upon it here, here and here, and probably elsewhere) is that of bogus laboratory or other diagnostic tests.
Early in my own education in modern quackery, I found it particularly distasteful not merely that quacks misuse laboratory tests, but that several commercial laboratories market misleading tests. To the untrained eye these laboratories appear to be legitimate, even to the point of their being approved by apparently legitimate certifying bodies. We’ll discuss that below, but first let’s look more closely at the psychiatrist’s recommendations to my friend’s daughter and at other examples of bogus tests.
In September 2008 I wrote a post on Misleading Ads for Back Pain Treatment. with particular attention to the bogus claims for the DRX 9000.
The Canadian Broadcasting Company (CBC) show “Marketplace” has just done a scathing exposé of so-called nonsurgical spinal decompression treatment with machines like the DRX 9000 and of some of the unscrupulous practitioners who offer it. Between the hidden camera footage and the weasel words of the chiropractor they interview, it’s quite entertaining.
A few months ago, I wrote about a particularly nasty form of cancer quackery known as the “German New Medicine” or Die Germanische Neue Medizin in German. As you may recall, the German New Medicine is based on the nonsensical idea that cancer arises from an internal emotional conflict. This conflict then results in what is called the “Dirk Hamer Syndrome” (DHS) or “Dirk Hamer focus” in the brain, named after Dr. Ryke Geerd Hamer‘s son Dirk, who was tragically shot in his sleep by Vittorio Emanuel, the last crown prince of Italy. After a prolonged course requiring multiple operations, Dirk succumbed to his wounds and died. Three years later, Dr. Hamer developed testicular cancer, and, in a perfect case of post hoc ergo propter hoc, Hamer decided that it was the psychic shock of his son’s death that had caused his cancer. Thus was born Die Germanische Neue Medizin, which, according to Hamer, promises a 95% or more chance of curing any cancer, no matter how advanced. Never mind that Hamer apparently underwent a combination of surgery and other “conventional therapies for his testicular cancer. Also never mind that these “Dirk Hamer Focus” to which Hamer pointed on CT scans of the brain appeared, more than anything else, to be artifacts of the imaging process and nothing real.
As I described in my previous post in October, the German New Medicine is a seriously dangerous form of cancer quackery that is not only worthless but in many cases blames the patient for having developed cancer. Evidence can be found in this video, where a proponent of German New Medicine gives as examples of psychic stress a “cancer blow” that comes from menopause, in which loss of estrogen supposedly leads women to feel that they “aren’t the woman they used to be” and that that conflict is manifest in the bone or an athlete’s anger because of an injury that screws up his ability to perform leading to an osteosarcoma of extremity.
Unfortunately, cancer quackery frequently evolves under the selective pressure of competition with other cancer quackeries and based on the unique environments in which various forms of quackery come to land. Since I first wrote my post about Die Germanische Neue Medizin, I’ve been meaning to address one of its offshoots. The particular offshoot that I plan to address is, in essence, the French cousin of Die Germanische Neue Medizin, and it’s called Biologie Totale, or Total Biology (Claude Sabbah’s official site is here, but it’s all in French). I first became aware of Biologie Totale about a year and a half ago through this news story:

Today I went to the one-day, 2nd Yale Research Symposium on Complementary and Integrative Medicine. Many of you will recall that the first version of this conference occurred in April, 2008. According to Yale’s Continuing Medical Education website, the first conference “featured presentations from experts in CAM/IM from Yale and other leading medical institutions and drew national and international attention.” That is true: some of the national attention can be reviewed here, here, here, and here; the international attention is here. (Sorry about the flippancy; it was irresistible)
I’ve not been to a conference promising similar content since about 2001, and in general I’ve no particular wish to do so. This one was different: Steve Novella, in his day job a Yale neurologist, had been invited to be part of a Moderated Discussion on Evidence and Plausibility in the Context of CAM Research and Clinical Practice. This was not to be missed.

The company that makes the Zeo Personal Sleep Coach kindly sent me one of their devices to try out. It’s a nifty little gadget, and if you are a techno geek, you would probably love it. It’s a fascinating toy; but for insomnia, there’s no evidence that it provides any benefit over standard treatment with sleep logs and sleep hygiene advice.
Polysomnography is done overnight in a sleep lab and costs around $1000. It records multiple parameters: EEG, EKG, EMG, breathing, O2, CO2, and limb movements. It is most commonly used to diagnose obstructive sleep apnea (OSA), a serious condition that is linked to hypertension, heart disease, diabetes, metabolic syndrome, stroke, and increased mortality. OSA can be effectively treated with CPAP and other measures. About 50% of snorers have sleep apnea. We typically think of it as a disease of obese, loudly snoring older men, but even young children can have it: snoring is probably never normal in children and should be investigated.
The Zeo is the first sleep monitor available for consumers to use at home. It doesn’t pretend to do what polysomnography does. It can’t diagnose sleep apnea. It is billed as an educational and motivational tool, not intended for the diagnosis or treatment of sleep disorders. A unit that looks sort of like an alarm clock sits on your bedside table and communicates wirelessly with a comfortable soft elastic headband that positions embedded sensors over your forehead to pick up your brain waves.

A MISCARRIAGE OF JUSTICE THAT HAD A (SORT OF) HAPPY ENDING
Back in September and then again last week, I wrote briefly (for me) about an incident that I considered to be a true miscarriage of justice, namely the prosecution of two nurses for having reported the dubious and substandard medical practices of a physician on the staff of Winkler County Hospital in Kermit, Texas. The physician’s name is Dr. Rolando Arafiles, and he happened to be a friend of the Winkler County Sheriff, Robert Roberts, who also happened to have been a patient of Dr. Arafiles and very grateful to him for having saved his life. The nurses, Anne Mitchell and Vickilyn Galle, were longtime employees of Winkler County Hospital, a fifteen bed hospital in rural West Texas. Although some of you may have seen extensive blogging about this before, I thought it very important to discuss some of the issues involved on this blog. Moreover, there is an aspect to this case that the mainstream media reporting on it has missed almost completely, as you will see. Finally, this case showed me something very ugly about my profession, not just because a doctor tried to destroy the lives of two good nurses through his connections to the good ol’ boy network in Winkler County
Let’s recap what happened, a story that reached its climax last Thursday. In 2008, Dr. Arafiles joined the staff of Winkler County Hospital (WCH). It did not take too long for it to become apparent that there were serious problems with this particular doctor. Mitchell and Galle, who worked in quality assurance were dismayed to learn that Dr. Arafiles would abuse his position to try to sell various herbal remedies to patients in the WCH emergency room and the county health clinic and to take supplies from the hospital to perform procedures at a patient’s home rather than in the hospital. No, it wasn’t the fact that Dr. Arafiles recommended supplements and various other “alt-med” remedies, it’s that he recommended supplements and various other “alt-med” remedies that he sold from his own business–a definite no-no both ethically and, in many states, legally. Mitchell reported her concerns to the administration of WCH, which did pretty much absolutely nothing. Consequently, on April 7, 2009, Mitchell and Galle anonymously reported their concerns to the Texas Medical Board (TMB). In June, WCH fired the two nurses without explanation.
