The BBC recently reported that a Guinean singer, Alama Kante, sang through her surgery in order to protect her voice. The reporting is unfortunately typical in that it emphasizes the seemingly amazing aspects of the story without really trying to put them into proper context. Specifically, the story emphasizes that hypnosis was used during the surgery, since Kante could not be placed under general anesthesia and still be able to sing, reporting:
“The pain of such an operation is intolerable if you are fully awake. Only hypnosis enables you to stand it,” he was reported as saying by to French publication Le Figaro.
“She went into a trance listening to the words of the hypnotist. She went a long way away, to Africa. And she began to sing – it was amazing,” he said.
Reports of major surgery being performed using self-hypnosis or hypnosis instead of anesthesia crop up regularly, because of the obvious sensationalism of such stories. I reported a similar case from 2008, for example. At least in this case the news report gave the critical piece of information, often missing entirely from such reports:
The Guinean singer, who is based in France, was given just a local anaesthetic and hypnotised to help with the pain during the operation in Paris.
A correspondent asked me to look into the science behind the health claims for turmeric. He had encountered medical professionals “trying to pass turmeric as some sort of magical herb to cure us from the ‘post-industrial chemical apocalypse.’” It is recommended by the usual promoters of CAM: Oz, Weil, Mercola, and the Health Ranger (who conveniently sells his own superior product, Turmeric Gold liquid extract for $17 an ounce).
Turmeric (Cucurma longa) is a plant in the ginger family that is native to southeast India. It is also known as curcumin. The rhizomes are ground into an orange-yellow powder that is used as a spice in Indian cuisine. It has traditionally been used in folk medicine for various indications; and it has now become popular in alternative medicine circles, where it is claimed to be effective in treating a broad spectrum of diseases including cancer, Alzheimer’s, arthritis, and diabetes. One website claims science has proven it to be as effective as 14 drugs, including statins like Lipitor, corticosteroids, antidepressants like Prozac, anti-inflammatories like aspirin and ibuprofen, the chemotherapy drug oxaliplatin, and the diabetes drug metformin. I wish those claims were true, because turmeric is far less expensive and probably much safer than prescription drugs. It clearly has some interesting properties, but the claims go far beyond the actual evidence. (more…)
NOTE ADDENDUM – Ed.
I’ll admit it: I’m a bit of a beer snob. I make no bones about it, I like my beer, but I also like it to be good beer, and, let’s face it, beer brewed by large industrial breweries seldom fits the bill. To me, most of the beer out being sold in the U.S., particularly beer made by Anheuser-Busch and MillerCoors can easily be likened to cold piss from horses with kidney disease (you need protein to get beer foam, you know), only without the taste. I have to be mighty desperate and thirsty before I will partake of such swill. I will admit that there is one exception, namely Blue Moon, which is manufactured by a division of MillerCoors, but that’s the only exception I can think of. Ever since I discovered Bell’s Oberon, a nice local (well, statewide, anyway) wheat ale, I can do without Blue Moon. Sadly, Oberon is only brewed during the spring and summer months; so when I want a similar bit of brew during the winter months sometimes I’m tempted by Blue Moon. Otherwise, I’m generally happy with one of the many craft and microbrews made by local brewers such as Short’s Brewing Company (whose brewpub I had the pleasure of visiting about a month ago) and Bells Brewery.
Despite my general hostility to Anheuser-Busch and MillerCoors products as examples of everything that is wrong with American beer, I have to say that I almost feel sorry for the people running those corporations right now. Unfortunately, they’ve fallen victim to the latest quack making a name for herself on the Internet by peddling pseudoscience. As is my wont, I’ll go into my usual excruciating detail shortly. But first, to whom am I referring?
I knew that Jann was thinking of writing about reiki and fraud, but did not know the details of her most excellent discussion from yesterday until I had finished my penultimate draft for today. Think of them as a match set, two perspectives on the same elephant.
Fraud: a person or thing intended to deceive others, typically by unjustifiably claiming or being credited with accomplishments or qualities.
There are numerous activities that one human will offer another in exchange for money that are completely divorced from reality.
Astrology. Total bunkum.
There is no force, known or unknown, that could possibly affect us here on Earth the way astrologers claim. Known forces weaken too fast, letting one source utterly dominate (the Moon for gravity, the Sun for electromagnetism). An unknown force would allow asteroids and extrasolar planets to totally overwhelm the nearby planets…
Study after study has shown that claims and predictions made by astrologers have no merit. They are indistinguishable from chance, which means astrologers cannot claim to have some ability to predict your life’s path.
Although 48% of Americans think astrology is a science, as best I can tell astrology is not part of the curriculum at any astronomy division or program. Astronomers know it is bunkum and avoid it . (more…)
The Center for Integrative Medicine at the Cleveland Clinic sells reiki treatments (also here) to patients with cancer, fertility issues, Parkinson’s Disease and digestive problems, as well as other diseases and conditions. The Center’s website ad describes reiki as
a form of hands-on, natural healing that uses universal life force energy . . . [a] vital life force energy that flows through all living things. This gentle energy is limitless in abundance and is believed to be a spiritual form of energy. The Reiki practitioner is the conduit between you and the source of the universal life force energy. . . You may experience the energy as sensations such as heat, tingling, or pulsing where the practitioner places her hands on your body, or you may feel these sensations move through your body to other locations. This is the energy flowing into you.
This “universal life force energy” is described as having certain positive effects on one’s own energy, such as “energetically balancing” one physically, replenishing one’s supply of energy, improving distribution of that energy in the body, and dissolving “energy blockages.” It also increases one’s “vibrational frequencies,” although how these frequencies relate to one’s energy, or to anything else for that matter, is not made clear.

Prolotherapy is a treatment technique used for chronic myofascial pain, back pain, osteoarthritis, or sports injury. It involves repeated injections of dextrose solution or other irritating substances into the joint, tendon, or painful tissue in order to provoke a regenerative tissue response. Similar techniques have been used for about a century, but the first formal publication describing prolotherapy dates back to 1956, by Dr. George Hackett. He wrote:
Within the attachment of weakened ligaments and tendons to bone, the sensory nerves become overstimulated by abnormal tension to become not only the origin of specific local pain, but also definite areas of referred pain throughout the body to as far as the head, fingers and toes from specific relaxed ligaments and tendons.
Prolotherapy. A treatment to permanently strengthen the “weld” of disabled ligaments and tendons to bone by stimulating the production of new bone and fibrous tissue cells has been developed.
Initially the concept, referred to a sclerotherapy, was that the injections formed scar tissue to stabilize the joint, tendon, or ligament. The newer concept, called prolotherapy, is that the injections provoke the proliferation of tissue, allowing for limited regeneration. (more…)
What AMD does to vision
Four years ago I wrote about the premature marketing of a diet supplement for macular degeneration before the results of a trial to test it were available. Now that we know the results of that trial, a follow-up post is in order.
Age-related macular degeneration (AMD) is a leading cause of blindness. The incidence increases with age; it affects 10% of people by age 66-74 and 30% of people by age 75-85. There are known risk factors including genetics and smoking, but there is no effective prevention. There are multiple diet supplement products on the market that are advertised as “supporting eye health.” Some are based on evidence from randomized, controlled studies; but the advertising hype goes beyond the evidence and tends to mislead consumers. There is evidence that supplementation may slow the progression of moderate to severe AMD, but there is no evidence that supplements are effective in milder disease or for preventing AMD from developing in the first place.

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.

I know by now I shouldn’t be, but I am still amazed by how readily so many people buy into the seemingly endless array of bogus sCAM nostrums. Many are marketed and hawked for the treatment or prevention of diseases that are poorly managed by science-based medicine. There are countless examples of dietary supplements that are purported to effectively treat back and joint pains, depression, anxiety, autism, chronic pain, and chronic fatigue; the list goes on and on. The lure for these treatments is at least understandable and, although frustrated that scientific literacy and rational thought loses out, I empathize with the desire to believe in them. On the other end of the spectrum is the even more ethically corrupt substitution of safe and effective treatments with products that are not. I encountered what I find to be possibly the most frightening and dangerous example of this recently at my practice. A family new to the area called to schedule a routine health-maintenance visit for their 5-year-old daughter. When our nurse reviewed the medical records the mother had faxed over, she noted that the child was unimmunized and explained to her that she would need to begin catch-up vaccinations. The mother matter-of-factly stated that her daughter was actually fully vaccinated with a vaccine alternative. She had received a series of homeopathic vaccines from a naturopath. I am not going to discuss this egregious example of sCAM here, though it was addressed in previous SBM posts.1,2 Instead I’d like to focus on another part of the sCAM spectrum. Here lies a form of sCAM that, in some ways, is even more difficult for me to comprehend. These are products invented, marketed, and sold solely for the treatment or prevention of fictitious diseases or problems that exist only in the realm of fantasy. (more…)
The Canadian Parliament, hypothetically protecting consumers since Confederation.
One of the most pervasive yet appealing health myths is the idea that natural equals safe. It’s a statement that’s repeated constantly by manufacturers of supplements and “natural” health products. It’s been the primary argument used, with considerable success, to give these products completely different regulatory structures than exist for drug products. Weaker regulation of supplements and natural health products has been a boon to manufacturers, but the same can’t be said for consumer protection. It’s effectively a buyer-beware marketplace in most parts of the world, with little accurate information available to consumers. But supplement manufacturers aren’t content with the minimal regulation that’s currently in place – they want health “freedom”. In this case, “freedom” means the right to sell any product, while being exempted from safety and regulatory requirements. New Canadian legislation is poised to raise safety standards for drugs and enhance the ability of regulators to recall dangerous products, yet consumers of natural health products are left behind. The legislation proposes to exempt anything considered a “natural health product”. This is not only bad public policy, but it has the potential to cause avoidable harm. After all, shouldn’t users of supplements and natural health products be entitled to the same safety and quality standards as those that use prescription drugs? If the supplement industry gets its way, the answer will be “no”. (There is an opportunity until June 10 for you to provide feedback on this legislation – see below.) (more…)
