Thirty years in Moukden
A mythology has grown up around traditional Chinese medicine (TCM). The ancient wisdom of the inscrutable Orient supposedly helped patients in ways that modern science-based medicine fails to understand or appreciate. A typical claim found on the Internet: “The ancient beliefs and practice of traditional Chinese medicine have been healing people for thousands of years.”
As Steven Novella has said, “TCM is a pre-scientific superstitious view of biology and illness, similar to the humoral theory of Galen, or the notions of any pre-scientific culture”. TCM really hasn’t been doing a creditable job of healing people for thousands of years. A book that was brought to my attention by one of our readers (thank you!) provides a unique insight into what Chinese medicine was really like circa 1900. I wish everyone who believes in ancient Chinese medical wisdom would read the chapter on Chinese medicine in this book. It provides a much-needed reality check. (more…)
I suspect there is more published about traditional Chinese medicine than any other SCAM. Here are some of the recent curiosities of TCM.
The little girls laughed about the germs, because they didn’t believe in them; but they believed about the disease, because they’d seen that happen. Spirits caused it, everyone knew that. Spirits and bad luck. Jack had not said the right prayers.
– Oryx and Crake
I long ago gave up on the idea that there are a finite number of pseudo-medical treatments. Anything a human can imagine will probably be used as a SCAM intervention. I remain amazed at the permutations that occur in the pseudo-medical world, not unlike the mix and match bioforms in Oryx and Crake.
Not everyone knows basic anatomy and physiology that allows for understanding of disease. Instead, people often rely on metaphor and magic for their understanding, especially in the world of pseudo-medicine. Sympathetic magic lies at the heart of many SCAMs. (more…)
You might have noticed that I didn’t produce a post last week, something that’s unusual for me, given how prolific I have been in the blogosphere. One reason was personal. The other reason was that last weekend I was attending the annual meeting of the American Society of Clinical Oncology (ASCO) meeting in Chicago. I also must confess that, while I was there, I caused a bit of a stir on the meeting hashtag (#ASCO14) in the name of science-based medicine (SBM) on Twitter under my handle @gorskon. (What? You aren’t following me on Twitter? Get thee hence to my Twitter feed and add me. I’ll wait. Did you do it yet? Good. Now we can move on.) Of course, I know what you’re thinking: Cuddly, lovable me? Causing trouble? Making sure that I’ll almost certainly never be invited to be an official social media doc or to participate in panels on social media at ASCO, despite my extensive experience blogging, using Twitter, and just in general being a pain in the rear online to those who promote quackery and quackademic medicine? Perish the thought!
Of course, it was for just that reason that I was making a bit of a stir on Twitter. ASCO is one of the biggest (if not the biggest) and most organized oncology meetings out there, and there were several people considered “social media rock stars” in the world of oncology such as Mike Thompson, Deanna Attai, Matthew Katz, and Robert Miller live Tweeting the meeting, along with those viewed, correctly or incorrectly, as lesser lights, such as myself. In any case, on Sunday I noticed that a lot of people, including the official ASCO Twitter feed @ASCO, were Tweeting and re-Tweeting a link to this official story from ASCO, “Integrative Oncology Can Add Benefit to Traditional Cancer Treatments.” It was a description of a session that had been held on Saturday morning, Integrative Oncology: The Evidence Base, which, unfortunately, I had missed due to circumstances entirely beyond my control. Fortunately, however, ASCO is benevolent (not to mention that it also justifies the high cost of meeting registration) by providing immediate access to recordings of every major session, not to mention the slide sets used. If I couldn’t be there in person, at least I could cruise on over to the ASCO website and use my access to the 2014 virtual meeting to see what sort of quackademic medicine was being featured at ASCO.

Bloodletting: a good reason to discard disproven therapies
All of us at SBM have repeatedly expressed frustration at the continuing influx of pseudoscience into the health care system. Judging from comments posted on this site and private communications we receive, our readers share this frustration but are at a loss to figure out how to get through to legislators and other policy makers. Unlike naturopaths and chiropractors, we don’t have the money to hire professional lobbyists. Fortunately, an opportunity to sound off against SCAMs has presented itself, completely free of charge.
Now that the Affordable Care Act enrollment debacle is dying down, the Department of Health and Human Services (HHS) is turning its attention to divining just what the heck Section 2706 of the ACA, the non-discrimination provision, means. (Actually there are other federal agencies involved; to simplify things, here we’ll refer to them collectively as “HHS.”) HHS has opened the issue to public comment, but only until June 10. Let’s take a look at why this is important and what you can do about it.
(There are providers other than chiropractors, naturopaths and acupuncturists involved in this fight. For example, you’ll see public comments from nurse anesthetists and nurse practitioners. But I’m not worried about providers who stick to science.) (more…)
Legislative Alchemy is the process by which credulous state legislators turn practitioners of pseudoscience into state-licensed health care professionals. In addition to unleashing quackery such as homeopathy, colonic irrigation, moxibustion, reiki, cranial sacral therapy and the detection and correction of subluxations on the public, these practice acts typically give chiropractors, naturopaths and acupuncturists the freedom of being governed by their own regulatory boards, to which the practitioners themselves are appointed. The boards, in turn, write the administrative rules governing practitioners and handle public complaints about their services. In the worst cases, legislatures simply hand out the privilege of practicing medicine to pretty much anyone.
State practice acts also establish the education and training standards for practitioners by requiring graduation from their accredited schools. Here the federal government lends a hand, by turning accreditation over to private agencies run by the practitioners themselves. The federal government also supports the schools by giving them taxpayer-funded student loans and research money. (more…)
Dr. David L. Katz is apparently unhappy with me. You remember Dr. Katz, don’t you? If you don’t, I’ll remind you momentarily. If you do, you won’t be surprised. Let me explain a bit first how Dr. Katz recently became aware of me again.
Last week, I posted a short (for me) piece about something that disturbed both Steve Novella and myself, namely Traditional Chinese herbalism at the Cleveland Clinic? What happened to science-based medicine? Steve had blogged about it as well a couple of days earlier. In actuality, it was a post that had originally appeared at my not-so-super-secret other blog, and, in my characteristically slightly arrogant way, I thought it was good enough that it deserved to be showcased here at Science-Based Medicine. To my surprise, Maithri Vengala over at The Healthcare Blog noticed and asked me if I would mind letting her post it over there. Never being one to turn down a request to showcase my work to a wider (or at least different) audience, I gave her my permission. The result was that my post ended up being published here, and I thought nothing more of it.
Until yesterday, that is.
Yesterday, thanks to the magic of Google Alerts, I became aware that Dr. David Katz was very unhappy with my post. At the very least, he strongly disagreed with it, so much so that he felt the need to respond. Naturally, he chose as his venue The Huffington Post, which is well known as a bastion of quackery, antivaccine pseudoscience, and Deepak Chopra-inspired magical thinking, to respond. Indeed, so bad is HuffPo (as it’s “nicknamed”) that Steve Novella and I have both referred to it as waging a “war on medical science,” and HuffPo has been a frequent topic of discussion on this very blog for its abysmal record of publishing pseudoscience, a record that goes back to its very beginning in 2005, when antivaccinationists flocked to the fledgling blog and news site. And that doesn’t even count all the nonsense from Deepak Chopra and even promotion of outright cancer quackery.
There are many forms of Traditional Chinese Medicine (TCM), and many have the same underlying theory: they stimulate non-existent acupuncture points to alter the flow of non-existent qi. For each form of TCM there are many variations on a theme. There are, for example, a half-dozen styles of acupuncture and multiple forms of cupping all trying to move the qi. That qi is an untameable beast, hard to corral into a proper gate even by the best acupoint wrangler.
There is, fortunately, yet another way, moxibustion, to alter that most intractable mysterious life energy.
Moxibustion is the burning of mugwort over acupoints.
What is mugwort? I resist the urge to make a Harry Potter pun about where Muggles go to school. No wait, I just did. Sorry. You know the old saying: yield to temptation, it may not pass you way again. Mugwort is a member of the daisy family, related to ragweed and, like ragweed, a common cause of hay fever. It is also used in food and was used in beer before hops was discovered.
Always start with an excuse. I have been ill for the last 10 days. I suspect I picked up an infection from the woman I slept with in Vegas.* I normally go through the day at warp 5 (I do not want to destroy space-time), but this illness has reduced my mental functioning in the evening to one-half impulse at best, with thoughts moving at the speed of a cold Oregon slug. So bear with me.
There can be an odd popularity to medicine. I see this in antibiotics usage. When a patient is admitted to the ICU with sepsis, while awaiting cultures you try and kill all the likely bacteria that may be trying to kill the patient. At any given time most doctors can only remember two antibiotics and the current popular duo is vancomycin and pipericillin/tazobactam. It is a reasonable choice, one of many combinations that would treat most patients with sepsis. I am not certain how this combination became so popular, although I have been told that the pipericillin/tazobactam reps have been very active at the Universities with medical students and residents. As the adage goes, “Give me a student until he is seven and I will give you the doctor.”
There are also popular trends in alternative medicine as well. Every now and then there is a flurry of mentions on the interwebs suggesting that a pseudo-medicine has become all the rage. Or maybe it is just the echo chamber that is the interwebs.
This week it is Oil Pulling Might Be The Next Big Thing — Or Not and What is cupping? Lena Dunham the latest celeb to try the ancient Chinese remedy for pain relief. (more…)
As some may know I am infectious disease doctor. Urinary tract infections (UTI) butter my bread. Figuratively speaking. There is an enormous amount known about the pathophysiology of UTI’s. It is both a common and complex problem. But for all our knowledge, chronic and recurrent UTI’s remain a vexing issue for the patient and the doctor.
One reason people develop recurrent UTI’s is not because of altered chi along meridians altered by needles stuck in the skin distant from the bladder. That would be ridiculous. I like reasoning from basic principles. Given what we know about anatomy, physiology and microbiology, how might acupuncture interfere with the development of a urinary tract infection? Would it prevent colonization with pathogenic E. coli? Prevent retrograde travel of bacteria up the urethra into the bladder? Stop E. coli from binding to uroepithelial cells? Have a bactericidal or bacteriostatic effect?
None of the above seem likely. To my mind, postulating any of the above as a potential mechanism for acupuncture as a preventative for UTI’s would be ludicrous. And spare me your Boosting the Immune System, a concept that exists as a marketing tool, not a useful therapeutic intervention. My boss used to say that many an academic career floundered on attempting to prevent and treat UTI’s using an immune system approach. With some exceptions, and there are always exceptions, recurrent UTI’s in normal humans are usually due to anatomic or microbiological anomalies.
Despite its popularity, it is clear that acupuncture is not based on reality and, like all pseudo-medicine, only has demonstrable efficacy in poorly-designed studies. Acupuncture displays the usual progression of all pseudo-medicines. Increasingly-well-done studies show decreasing effect until a study that removes all bias shows it to be no better than placebo. Which one would expect for an intervention based on fantasy. Prior plausibility (the toy boat of SBM, try saying it three times very fast) would predict that acupuncture is worthless. And that should be acupunctures, all 6 styles are an elaborate ritual with no more likelihood of efficacy than the superstitions in a Budweiser commercial. (more…)
Ngram is a Google analytic tool/way to waste lots of time on the internet, a byproduct of Google’s scanning millions of books into its database. In a matter of seconds, Ngram scans words from about 7.5 million books, an estimated 6 percent of all books ever published. Type a word or phrase in the Ngram Viewer search box and in seconds a chart of its yearly frequency will appear. You can also search for a series of words or phrases and the Viewer will provide a color-coded chart comparing frequency of use. More sophisticated searches (e.g., making the search case sensitive, or not) are also possible.
As explained in the New York Times, researchers “have used this system to analyze centuries of word use, examining the spread of scientific concepts, technological innovations, political repression, and even celebrity fame.” Erez Aiden, a computer scientist who helped create the word frequency tool, says he and his co-researcher, Jean-Baptiste Michel, wanted “to create a scientific measuring instrument, something like a telescope, but instead of pointing it at a star, you point it at human culture.” In fact, the title of their new book is Uncharted: Big Data as a Lens on Human Culture. Still, they caution that, like other scientific tools, Ngram’s results can be misinterpreted. An example: the fax machine. If you query that term, it looks as if the fax appears almost instantaneously in the 1980s. In reality, the machine was invented in the 1840s but was then called the “telefax.”
If Ngram can search for scientific concepts, how about unscientific concepts? What might a search of unscientific concepts tell us about our human culture? Let’s find out. (more…)
