Cranial Manipulation and Tooth Fairy Science

Tooth Fairy Science is science that studies a phenomenon that doesn’t exist. You can do studies on the Tooth Fairy; for instance, comparing how much money she leaves to kids in different socioeconomic groups. You can do studies on the memory of homeopathic water. You can do studies on the therapeutic effects of smoothing out wrinkles in the imaginary human energy field with therapeutic touch. Or you can do studies of craniosacral therapy. “Therapeutic Effects of Cranial Osteopathic Manipulative Medicine: A Systematic Review,” by Jakel and Hauenschild, was published 2011 in the Journal of the American Osteopathic Medical Association. It is a perfect example of Tooth Fairy Science.

In the 1930s, William G. Sutherland, DO looked at a disarticulated skull and noticed that the sutures were beveled, like the gills of a fish. He concluded that this indicated articular mobility for a respiratory mechanism. He invented cranial osteopathic manipulation to allegedly move the bones of the skull relative to each other for therapeutic benefit.

In the 1970s, John E. Upledger developed this idea further, inventing craniosacral therapy (CST). It postulates rhythmic fluctuations of the cerebrospinal fluid (CSF), mobility of the cranial bones and dural membranes, and involuntary motion of the sacrum. The CST practitioner palpates the skull, senses pulsations transmitted to the skull by the CSF, gently moves the skull bones relative to each other, and thereby releases restrictions to the flow of CSF, which somehow restores health in an astounding variety of human illnesses.

Frightening Breast Cancer Patients with Bad Science

No Time to Waste: Avoidant Coping Style Scrambles Circadian Rhythms in Breast Cancer Patients, warned the headline of an article in Clinical Psychiatry News. The article went on to claim

Even in the earliest days following a diagnosis of breast cancer, maladaptive coping styles are associated with a disruption in circadian rhythms –which are proven in metastatic disease to be a prognostic indicator of mortality. The surprising finding… holds potentially profound implications for the timing and tailoring of psychosocial interventions in newly diagnosed patients.

And it invoked psychoneuroimmunology for an authoritative sounding warning to breast cancer patients:

The fact that circadian disruption was significant in a subset of patients a mean 19 [sic] days after diagnosis suggests that there may be no time to waste in identifying and treating potentially maladaptive coping responses that could impact not only their adjustment, but also their prognosis.

Women who are diagnosed with breast cancer, enroll yourself immediately in a stress reduction program or support group, if you want to stem the progression of your disease and prolong your life! If you have metastatic disease, maybe you can blame your “maladaptive coping,” your inept handling of the days and weeks immediately after your diagnosis. Such frightening messages to women who are vulnerable because they have just received their diagnosis should require high standards before being released. This article reeks of hype and distortion, starting with its emotional title, No Time to Waste and “Scrambles Circadian Rhythms,” continuing with claims of “profound implications for the timing of psychosocial interventions,” and ending with an exhortation to breast cancer patients that “early breast cancer patients certainly warrant paying closer attention to coping from Day 1.”

The issue is not just skewered science, because  the article contains information that is easily misunderstood without a proper context. Breast cancer patients are urged to take get psychosocial intervention under the threat that if they do not, they are missing an opportunity to control the progression of their disease. This is an example of the irresponsible nonsense that I have been complaining in the past two blogs. There is simply no evidence that psychological interventions can slow progression of cancer or extend life. Claims to the contrary serve to burden cancer patients with an unrealistic responsibility for the outcome of their medical condition. Patients who experience progression to a terminal condition are provided with an irrational sense that they are to blame because they did not take the right steps, namely avail themselves of effective psychological interventions. This article implies that breast cancer patients with an unfavorable course have brought it on themselves by getting too stressed out.

It’s not clear whether journalist Betsy Bates Freed, PsyD. actually interviewed the authors of the study on which the story is based. Media coverage often offers direct quotes that appear to have been obtained directly from authors when they actually come from the scientific article.  In this particular case, Freed provides a highly speculative direct quote that “circadian cycles regulate tumor growth” as if it came directly from the mouth of the lead author of the study. For the record, there is some evidence of an association between circadian rhythms and progression of metastatic breast cancer, but it is not clear that it is causal or  affects”regulation” or in what direction any causal arrows run. Importantly, such findings have not been replicated with early breast cancer patients.

Clinical Psychiatry News is not some dubious CAM website, but an Elsevier published monthly newspaper with an advisory editorial board with recognizable scientist and clinician psychiatrists. It has largely free web access because of pharmaceutical company support. One has to question what editorial control over content is exerted before releasing articles like No Time to Waste.

The Mind in Cancer: Low Quality Evidence from a High-Impact Journal

My science writing covers diverse topics but increasingly concerns two intertwined themes in cancer and psychology. First, I bring evidence to bear against an exaggerated role for psychological factors in cancer, as well as against claims that the cancer experience is a mental health issue for which many patients require specialty mental health interventions. Second, I explore unnoticed social and organizational influences and publishing practices, which limit evaluation of the best evidence for theories and practices claiming to be evidence based, especially those recommended (and even mandated) by professional organizations and accrediting bodies.

I benefit from a great set of international collaborators, and my colleagues and I have repeatedly  debunked claims that psychological interventions increase the survival time of cancer patients by improving their immune systems. Wally Sampson and Bernie Fox provided important inspiration for these efforts. A key source of such claims is the classic Lancet study by David Spiegel, which I will dissect in a later post for ScienceBasedMedicine.org (for now, see our published critique of Spiegel).

Chiropractic and Deafness: Back to 1895

Chiropractic originated in 1895 when D.D. Palmer claimed to have restored deaf janitor Harvey Lillard’s hearing by manipulating his spine. This makes no anatomical sense, and few if any chiropractors claim to be able to reverse deafness today. But now a chiropractic website is attempting to vindicate D. D. Palmer. They list deafness among a long (wrong) list of “Conditions That Respond Well to Chiropractic”

They list 6 supporting studies. Three are case reports, two are case series, and one is a review of the literature that is labeled in its title as “A Search to Validate” D.D. Palmer. (more…)
