Therapeutic Touch Pseudoscience: The Tooth Fairy Strikes Again

When tested, therapeutic touch (TT) practitioners failed to detect the human energy field they thought they could feel. Experimental setup from Rosa et al., from JAMA, 1998, 279 (13)

When tested, therapeutic touch (TT) practitioners failed to detect the human energy field they thought they could feel. Experimental setup from Rosa et al., from JAMA, 1998, 279 (13)

A study out of Iran titled “Therapeutic touch for nausea in breast cancer patients receiving chemotherapy: Composing a treatment” was recently published in the journal Complementary Therapies in Clinical Practice. It is a great example of the Tooth Fairy science that permeates much of the research in complementary and alternative medicine. In Tooth Fairy science, researchers attempt to study a phenomenon without first determining whether it exists.

What is therapeutic touch?

Therapeutic touch (TT) is a type of energy medicine; practitioners claim to be able to:

  1. sense a patient’s “human energy field” with their hands,
  2. manipulate the energy field by moving their hands near (but not touching) a patient’s skin surface, and
  3. thereby improve the patient’s health.

TT was the delusional invention of a nurse and a theosophist, and it has no scientific basis. Scientists can detect and measure minute energies down to the subatomic level, but they have never detected a “human energy field.” And when TT practitioners were tested on their ability to detect such a field, they failed miserably.

Therapeutic touch is pure vitalism, the belief in a soul or animating force,” writes Paul Ingraham, “exactly like the Force in Star Wars, and just as fanciful. Auras and life energy do not exist and cannot be felt, let alone manipulated therapeutically.”

Despite the combination of extreme implausibility and a total lack of evidence, TT is taught to nurses in many otherwise reputable institutions, and there are more than 90,000 practitioners worldwide. There is even a Therapeutic Touch International Association that claims TT is evidence-based. It is not.

TT practitioners believe they are helping patients. That belief is reinforced by seeing patients improve due to the natural course of illness, suggestion, and the “placebo” or nonspecific contextual effects of the provider/patient encounter. They allow confirmation bias to overcome scientific reality, and they do poorly-conceived research seeking further confirmation. Since the studies are designed to show that TT works rather than to ask if it works, they find evidence that is convincing to believers but not to the scientific community as a whole. (more…)

CAM use and chemotherapy: A negative correlation

It turns out that the use of certain forms of CAM makes it less likely that breast cancer patients will receive the chemotherapy they need.

It turns out that the use of certain forms of CAM makes it less likely that breast cancer patients will receive the chemotherapy they need.

So-called “alternative” medicine is made up of a hodge-podge of health care practices and treatments based on beliefs that are unscientific, pre-scientific, and pseudoscientific. These modalities include practices as diverse as homeopathy, traditional Chinese medicine, reflexology, reiki and other forms of “energy medicine” based on vitalism, chiropractic, and naturopathy, and that’s a short list of the quackery that falls under the rubric of the term “alternative medicine.” Unfortunately, this unscientific, pre-scientific, and pseudoscientific hodge-podge of treatments rooted in nonsense is rapidly being “integrated” into real medicine, thanks to an unfortunately influential movement in medicine whose members have been seduced into thinking that there might be something to them and view “integrating” them into medicine as means of practicing more “holistic” and “humanistic” medicine. This “integration” started out by being called “complementary and alternative medicine” (CAM) but now among believers the preferred term is usually “integrative medicine,” largely because it eliminates the word “alternative,” which implies (correctly) that the modality is not real medicine, and “complementary,” which implies a subsidiary status, a status of being nice to have but not essential.

Particularly harmful is the hostility towards conventional medicine that often strongly correlates with use of alternative medicine. Indeed, some people even choose to rely on alternative medicine instead of real medicine to treat cancer. Unsurprisingly, the results of such a decision are generally not very good. Actually, they are almost always terrible. Very, very terrible indeed. Not surprisingly, the use of alternative medicine is associated with bad outcomes. Cancer patients who might have survived die because of it. It’s not as though it hasn’t been studied either, although the main studies I’m aware of tend to look at the bad outcomes in patients who choose alternative medicine. There is another question, and it’s one that a new study published in JAMA Oncology last week seeks to answer. It’s a study that briefly made the news, producing headlines like:

Behold my power, quacks, and despair! Mike Adams publishes several defamatory articles about yours truly…

Mike Adams seems to view me this way. It started out funny, but isn't so funny any more.

Mike Adams seems to view me this way. It started out funny, but isn’t so funny any more. Of course, Galadriel was offered The One Ring and its great power, but declined it because she was afraid of what she would become. Maybe I am like Galadriel after all.

I decided to write this post for Science-Based Medicine because I’ve taken notice of recent posts Mike Adams has written about me, mainly because they are riddled with misinformation, fabrications, and lies. Even though at least two of his claims about me made me laugh out loud because of their utter ridiculousness, much of the rest of his recent writing about me has been downright defamatory, libelous even.

The stupid stuff

Before I get into the really nasty stuff, let’s look at the stupid stuff. It’s not that the nasty stuff isn’t also stupid, but here I arbitrarily decide to divide the discussion into parts about when Adams amuses me and when he disgusts me. If there’s one lesson I’ve learned from Adams’ attacks on me, it’s that, apparently, I have incredible power—possibly even superhuman! I mean, seriously. Adams really does seem to think that I have massive power over what Wikipedia does and does not publish about vaccines and medicine! Indeed, as I thought last night about what to write and even ended up staying up until 2 AM to do so (mainly because I was so exhausted after a day in the operating room that I crashed on the couch between 8 and 11 PM), I was half-tempted not to disabuse him of his apparent delusions about my overwhelming power. After all, if Adams really does think that I have so much power, why would I want to reveal to him the truth that I do not? On the other hand, far less amusing are Adams’ attempts to link Karmanos Cancer Center and me to the criminal Dr. Farid Fata, a lie by insinuation that is despicable even by his low standards. What should I expect, though, from someone who’s been running scams since Y2K and posting threats against GMO scientists?

Of course, I am not naïve enough to believe that Adams doesn’t actually know damned well that I don’t have that level of influence on Wikipedia. Rather, it’s all a sham, a con man’s patter, to convince his readers that I’m a major player in a conspiracy to manipulate health articles on Wikipedia from behind the scenes. He uses such fabricated stories as tools to fire up his gullible and stupid followers. Does Adams even realize how ridiculous his articles come across with their overwrought language? In fact, I laughed out loud when I read that Arianna Huffington and I “are not directly murdering children, but they are doing everything in their power to kill any truthful discussion about vaccine damage (that might save children)” and then this:

You’ve been diagnosed with breast cancer. How soon do you need treatment?

Breast Cancer Surgery
A new year is upon us yet again, and Science-Based Medicine has been in existence for eight years now. It seems only yesterday that Steve Novella approached me to ask me to be a contributor. Our part-serious, part-facetious predictions for 2016 notwithstanding, one thing about 2016 is certain: I will almost certainly encounter some form of cancer quackery or other and deconstruct it, probably multiple forms. In any case, a topic I’ve been meaning to write about is based on a couple of studies that came out three weeks ago that illustrate why, even if a patient ultimately comes around to science-based treatment of his cancer, the delay due to seeking out unscientific treatments can have real consequences.

When a patient with breast cancer comes in to see me, not infrequently I have to reassure her that she doesn’t need to be wheeled off to the operating room tomorrow, that it’s safe to wait a while. One reason, of course, is that it takes years for a cancer to grow from a single cell to a detectable mass. The big question, of course, is: What is “a while”? Two studies published online last month attempt to answer that question. One study (Bleicher et al) comes from Fox Chase Cancer Center and examines the effect of time to surgery on breast cancer outcomes; the other (Chavez-MacGregor et al) is from the M.D. Anderson Cancer Center and examines the effect of time to chemotherapy on outcome. Both find a detrimental effect due to delays in treatment.

Worshiping at the altar of the Cult of the Brave Maverick Doctor

Death of Cancer

One of my favorite television shows right now is The Knick, as I described before in a post about medical history. To give you an idea of how much I’m into The Knick, I’ll tell you that I signed up for Cinemax for three months just for that one show. (After its second season finale airs next Friday, I’ll drop Cinemax until next fall.) The reason why I’m bringing up The Knick (besides I love the show and need to bring it up at least once a year) is because an article by Malcolm Gladwell in The New Yorker entitled “Tough Medicine“, which is a commentary based on a new book on cancer by a veritable god of cancer research, Vincent T. DeVita, Jr., immediately resonated with a storyline in this season of The Knick. I haven’t yet read The Death of Cancer: After Fifty Years on the Front Lines of Medicine, a Pioneering Oncologist Reveals Why the War on Cancer Is Winnable–and How We Can Get There by Vincent T. DeVita and Elizabeth DeVita-Raeburn, but I want to. I can tell, though, that there will be parts of the book I find annoying just from Gladwell’s take on it, which approvingly describes DeVita as railing against the cautiousness and incremental nature of today’s cancer research. To give you an idea of where Gladwell’s coming from, I note that his article shows up in the title bar of my web browser not as “Tough Medicine” but rather “How To Cure Cancer”, even as the title on the web page itself remains “Tough Medicine”. On the other hand, the article does conclude with Gladwell demonstrating a better understanding of the disadvantages of what DeVita is proposing than it seems that he will in the beginning. In fact, it is Gladwell who is more reasonable than his subject, although he does appear share DeVita’s apparent assumption that potentially all cancer patients are savable if only we try hard enough.

Sarah Hershberger: “Health freedom” and parental rights vs. child welfare

Sarah Hershberger, pictured with her family in a 2014 Reason.tv video.

Sarah Hershberger, pictured with her family in a screenshot from a 2014 Reason.tv video.

One of the more depressing topics that I regularly write about on this blog includes of analyses of news stories of children with cancer whose parents decided to stop science-based treatment (usually the chemotherapy) and use quackery instead. There are, of course, variations on this theme, but these stories take form that generally resembles this outline: A child is diagnosed with a highly treatable cancer with an excellent cure rate. Standard science-based treatment is begun, but the child suffers severe side effects from the chemotherapy. After an incomplete course of chemotherapy, the parents, alarmed at their child’s suffering, start balking at further chemotherapy, either because the child refuses further treatment or because they do. At some point in this process the parents become aware of the claims of practitioners of this or that alternative medicine, who tell them that their child’s cancer can be cured without toxic chemotherapy, and, wooed by the siren song of a promise of a cure without suffering, the parents choose that instead. At this point, physicians, alarmed at the parents’ choice, call in their state’s child protective services team, and a court battle ensues. Sometimes the court battle results in an order that the child complete conventional therapy, as it did with, for example, Daniel Hauser or Cassandra Callender. Sometimes it ends with a compromise in which the child and/or parents can choose an unconventional practitioner, as in the case of Abraham Cherrix. All too often the courts utterly fail to protect children with cancer, as the Canadian courts did in the cases of Makayla Sault and JJ. Not infrequently, if the court rules against the parents, the parents flee with their child to avoid treatment, as happened with Daniel Hauser, Abraham Cherrix, and Sarah Hershberger. Usually, they ultimately come back.

However they turn out, over the years of looking into them I’ve found that these stories tend to bear a depressing similarity and predictability. For example, if the child does well, it is always attributed to the alternative treatment, even when the child received a significant amount of conventional therapy. This attribution derives from a fundamental misunderstanding of how the treatment of cancer works in that the problem with incomplete cancer treatment is not that it can’t cure the cancer but that it has less of a chance of doing so. As I’ve explained many times, the reason that treatment regimens for many pediatric cancers involve two years’ worth of chemotherapy is that over time pediatric oncologists learned the hard way that, although the first cycle of chemotherapy (usually called induction chemotherapy) can lead to remission, without the additional cycles the chances of recurrence are very high—unacceptably so. Consequently, children who stop chemotherapy early can be in remission; they’ve just been put at a high risk of recurrence.

The Gerson protocol, cancer, and the death of Jess Ainscough, a.k.a. “The Wellness Warrior”

The Wellness Warrior website now redirects to this photo.

The Wellness Warrior website now redirects to this photo.

Less than four days ago, a young Australian woman died of a very rare type of cancer. Most of my American and probably many of my European readers have never heard of her, but in Australia she had become quite famous over the last seven years as a major proponent of “natural health.” Her name was Jess Ainscough, but, like a certain American woman who has become famous for promoting dubious science, she was better known by her “brand” name. That brand name was The Wellness Warrior.

I first encountered Ms. Ainscough about a year and a half ago and have been intermittently following her career ever since. I’ve even blogged about her three or four times during that period over at my not-so-super-secret other blog. However, for whatever reason, even though it was my intent to write about her here on Science-Based Medicine, I never got around to it. Her death prodded me to write now, because her tale is a cautionary one important enough that I believe there should be something written here about it. Given that, those of you who follow my cubical other self will find some of this post repetitive. However, think of it as the first opportunity I’ve had to tell the story from beginning to end, along with a major deconstruction of the Gerson protocol. (Yes, unfortunately the Gerson protocol figures heavily in this story.) It’s a story that has led to the deaths of at least two people, and whose harm to others is impossible to quantify, given that the reach of The Wellness Warrior was long, at least in Australia.

An aboriginal girl dies of leukemia: Parental “rights” versus the right of a child to medical care

makayla-sault-v2

One topic that keeps recurring and obligating me to write about it consists of critically analyzing stories of children with cancer whose parents, either on their own or at the behest of their child, stop or refuse chemotherapy or other treatment. It is, sadly, a topic that I’ve been discussing for nearly a decade now, starting first on my not-so-super-secret other blog and continuing both there and here. Indeed, the first post I wrote about this problem was in November 2005, a fact that depressed me when I went back through the archives to find it because so little has changed since that time.

I was painfully reminded of this last week when stories started circulating in the media about the death of Makayla Sault, an Ojibwe girl and member of the New Credit First Nation in Ontario:

The entire community of New Credit is in mourning today, following the news of the passing of 11 year old Makayla Sault.

The child suffered a stroke on Sunday morning and was unable to recover. Friends and family from across the province travelled to New Credit First Nation today to offer condolences, share tears and pay their respects.

Ontario fails to protect the life of a First Nations girl with cancer

First Nations

A few weeks ago, Steve Novella invited me on his podcast, The Skeptics’ Guide to the Universe, to discuss a cancer case that has been in the news for several months now. The case was about an 11-year-old girl with leukemia who is a member of Canada’s largest aboriginal community. Steve wrote about this case nearly a month ago. Basically, the girl’s parents are fighting for the right to use “natural healing” on their daughter after they had stopped her chemotherapy in August because of side effects. It is a profoundly disturbing case, just as all the other cases I’ve discussed in which children’s lives are sacrificed at the altar of belief in alternative medicine, but this one has a twist that I don’t recall having dealt with before: The girl’s status as part of the First Nations. Sadly, on Friday, Ontario Court Justice Gethin Edward has ruled that the parents can let their daughter die.

The First Nations consist of various Aboriginal peoples in Canada who are neither Inuit nor Métis. There are currently more than 630 recognized First Nations governments or bands in Canada, half of which are located in Ontario and British Columbia. This girl lives in Ontario, which is basically just next door to Detroit, just across the Detroit River. Unlike previous cases of minors who refuse chemotherapy or whose parents refuse chemotherapy for them that I’ve discussed, such as Sarah Hershberger, an Amish girl whose parents were taken to court by authorities in Medina County, Ohio at the behest of Akron General Hospital, where she had been treated because they stopped her chemotherapy for lymphoblastic lymphoma in favor of “natural healing,” or Daniel Hauser, a 13-year-old boy from Minnesota with Hodgkin’s lymphoma whose parents, in particular his mother, refused chemotherapy after starting his chemotherapy and suffering side effects, there’s very little information about this girl because of Canadian privacy laws. I do not know her name. I do not know anything about her case except that she has acute lymphoblastic leukemia, that she started treatment but her parents withdrew her because of side effects.

Medicine past, present, and future: Star Trek versus Dr. Kildare and The Knick

mccoyvs20thcen

I’ve been a big Star Trek fan ever since I first discovered reruns of the original Star Trek episodes in the 1970s, having been too young (but not by much!) to have caught the show during its original 1966-1969 run. True, my interest waxed and waned through the years—for instance, I loved Star Trek: The Next Generation, while Star Trek: Enterprise and Star Trek: Voyager pretty much left me cold—but even now I still find myself liking the rebooted movie series. In the original series, my favorite characters tended to alternate between Spock, the Vulcan first officer and science officer on the Enterprise, and Dr. Leonard “Bones” McCoy, the ship’s chief medical officer. I sometimes wonder if my love of these two characters had anything to do with my becoming a doctor and researcher myself. It probably did.

One aspect of all the Trek shows that always interested me was its portrayal of medicine in the 23rd and 24th centuries. After all, what doctor wouldn’t like to have a device like the tricorder that he could wave over the patient and come up with an instant diagnosis and course of treatment? Who knew, of course, that nearly 50 years after the first Trek episode first aired, we would have technology that makes the communicators on the original series (TOS, for those Trek non-fans) look primitive and large by comparison and that we’d be well on the way to developing devices that can do some of what tricorders did on the show. Throughout all the shows and movies, the medical technology of a few hundred years in the future is portrayed as vastly superior to what we have now, with 20th century medicine at times denigrated by “Bones” McCoy and other Star Fleet medical personnel as barbaric quackery.

A confluence of events and media led me to want to explore a couple of questions. First, which procedures that we consider state-of-the-art science-based medicine will be considered “barbaric” 50 or 100 years from now? Second, is the contempt expressed for the medicine of the past (e.g., by “Bones” McCoy) justified? These are questions that I’ll explore a bit with the help of the Star Trek universe, a recent new cable television drama series, and a couple of articles that appeared on medical sites as a result of the premier of that series.
