We accept certain risks for the benefits of modern society. We pump explosive gas into homes, we run wires with potentially fatal electrical currents through our neighborhoods, and we ski at breakneck speeds down mountains for fun.
We also allow people to operate vehicles weighing thousands of pounds at speeds that are potentially deadly if a mishap occurs. In 2011 there were 32,367 motor vehicle deaths in the US (10.4 per 100,000 population). Interestingly, this is down quite a bit from previous years. As a percentage of population the highest motor vehicle death year was 1935, with 34,494 deaths, or 27.1 per 100,000. The highest absolute number of motor vehicle deaths was in 1970, at 52,627.
The number of deaths has been mostly trending down since 1996, which is interesting because over this same period of time cell phone use has risen tremendously. There are various reasons for the decreased in fatalities – helmet laws, seatbelt laws, cracking down on drunk driving, increased car safety, and intermediate drivers licenses for new drivers to name a few. These trends have probably obscured any increase in car accidents from using portable communication devices while driving.
Osteoarthritis is the “wear and tear” kind of arthritis that many of us develop as we get older. Cartilage becomes less resilient with age, collagen can degenerate, and inflammation and new bone outgrowths (osteophytes) can occur. This leads to pain, crepitus (Rice Krispie type crackling noises with movement), swelling and fluid accumulation in the joints (effusion), and can severely limit activity for some patients. Patellofemoral pain is one of the most common of the repetitive strain injuries and is like an early onset of arthritis.
Since knee osteoarthritis is such a ubiquitous annoyance, home remedies and CAM offerings abound. Previously we have covered a number of CAM options on this blog, including glucosamine, acupuncture, and several others. The American Academy of Orthopaedic Surgeons (AAOS) has just issued a 1200 page report evaluating the evidence for various treatments for knee osteoarthritis short of total knee replacement surgery. A 13 page summary is available online. They have done the heavy lifting for us, reviewing all the available scientific studies for evidence of effectiveness. Here’s what the science says: (I’ve highlighted the ones where the evidence is strong.) (more…)
Last week, I reviewed a long-expected (and, to some extent, long-dreaded) documentary by Eric Merola, a filmmaker whose talent is inversely proportional to his yen for conspiracy, pseudoscience, and quackery. Through a quirk of fate that couldn’t have worked out better if I had planned it myself, a long-expected investigation of the Burzynski Clinic by the BBC aired on its venerable news program Panorama last Monday. It was entitled, appropriately enough, Cancer: Hope for Sale? Ever since learning that the BBC was working on this back in January or February, skeptics have been looking forward to it with a mixture of anticipation and dread, anticipation because we expected that the Panorama crew would “get it” (in the interests of full disclosure, I will mention that I was interviewed over the phone by a Panorama producer and exchanged e-mails to answer questions and suggestions), but a bit of dread because we feared the bane of all news reporting on issues of science and medicine: false balance.
So now that the report was finally aired, how was it? You can either watch it on iPlayer (if you’re in the UK) or on YouTube (if you’re not, assuming it’s still there):
Chinese geranium, apparently a natural meth factory, making that bee a suspect
by Igor I. Bussel & Drey A. Pavlov
Jann Bellamy has recently authored an excellent piece on the limitations of the FDA and how the DSHEA actually protects the profits of supplement manufacturers rather than the health and well-being of consumers. Bellamy used the very poignant and currently “controversial” example of DMAA (methylhexanamine or 1,3-dimethylamylamine) to illustrate her point regarding the loopholes and lack of enforcement power of the FDA. The authors of this piece had been considering writing about DMAA and felt this would be an excellent time to further expound on Bellamy’s work. The goal of this article will be twofold: 1) to discuss the known history and pharmacology of DMAA, especially in regards to the basic methodology for evaluating novel substances or novel uses of substances in the context of lacking randomized, controlled trial-level evidence (i.e. the concept of science vs. evidence based medicine) and 2) how the DMAA story clearly and unequivocally demonstrates how the DSHEA allows for unscrupulous profiteers to game the system with little, if any, consequence and nothing but profit until the cost in lives forces the issue.
DMAA was originally developed by Eli-Lilly in 1948 and then later trademarked as Forthane to be used as a nasal decongestant (there are varying accounts but it seems that Eli Lilly patented the molecule in the early 1940s, trademarked and marketed it as Forthane in 1971 for allergic rhinitis, and then voluntarily withdrew it in 1983). The mechanism of action was vasoconstriction – the blood vessels in the nose would constrict so that less blood flow would lead to less nasal discharge. This is a mechanism used by common OTC nasal sprays like oxymetazoline (Afrin) and is indeed quite effective. However, Forthane was later withdrawn from the market because of significant side effects including headaches, tremors, and increased blood pressure. These effects likely occur because DMAA is structurally similar to amphetamine and as a result, the compound is not only a vasoconstricting agent but is also a central nervous system (CNS) stimulant.
If you grew up in the seventies, you may remember the same food fads as I do. There was the oat bran buzz that was replaced by the wheat germ movement, the family fondue set and the homemade yogurt maker. And for a while I remember my father making what I called “aquarium water” – a foul-looking jug sitting on the kitchen counter with a gelatinous white mass floating on top. Despite the assurances it was good for me, I declined the taste tests. They didn’t push it and I never volunteered to drink this “cure all”. I thought kombucha had gone the way of gelatin-based salads and entrees, until a friend told me she was drinking it. Not only is it still a home-brew darling, kombucha isn’t just for hippies: There’s probably some for sale at your local organic grocery. Yet after a bit of digging, kombucha culture still seems mired in the 1970s. It’s still touted as a panacea, and it’s still one of the more questionable folk remedies out there. (more…)
It’s frustrating to read yet another story of the process of developing a potential new medical treatment derailed by the current infrastructure of quackery that we have in this and other countries. This is one of the unmeasurable harms that results when pseudoscience is given regulatory, academic, and professional legitimacy. The press then celebrates the nonsense that results.
The basic story is often the same, with a few variations. First, however, let me describe what should happen when someone comes up with an idea for a new medical treatment.
Background research – The first step, whether the innovator is within or without the medical community, is to familiarize oneself with existing research. Is the idea plausible, has it been investigated before, are there any similar treatments that can act as a guide to predicting how this new treatment will work?
Note: Lest you think that SBM is becoming “turtles all the way down,” let me apologize for the duplication and explain that I had already written this right before I read Mark Crislip’s Turtle Agony article on Friday. My focus is different, and turtles were only a small part of my article, so I decided to leave the turtles in. If you prefer to avoid a turtle overdose, you can just skip the Turtlepuncture section and go on to the Motion Style Acupuncture section. They are clearly labeled for your convenience.
A group of Ridley sea turtles were rescued after being stranded during a cold spell that left them hypothermic and unable to function. In addition to the usual rescue and rehabilitation efforts, two of the turtles, Dexter and Fletcher Moon, were treated with acupuncture. It was intended to “decrease inflammation and swelling on their front flippers, restore a full range of motion on those limbs and help the animals regain their appetites.” It allegedly worked: their appetite and the use of their limbs improved. But without any controlled observations, this is only an anecdotal report and means very little. They might have recovered just as well without the treatment, for all we know.
Well, I’ve finally seen it, and it was even worse than I had feared.
After having heard of Eric Merola’s plan to make a sequel to his 2010 propaganda “documentary” about Stanislaw Burzynski, Burzynski The Movie: Cancer Is Serious Business, which I labeled a bad movie, bad medicine, and bad PR, I’ve finally actually seen the finished product, such as it is. Of course, during the months between when Eric Merola first offered me an “opportunity” to appear in the sequel based on my intense criticism of Burzynski’s science, abuse of the clinical trials process, and human subjects research ethics during the last 18 months or so, there has been intense speculation about what this movie would contain, particularly given how Merola’s publicity campaign involved demonizing skeptics, now rechristened by Merola as “The Skeptics,” a shadowy cabal of people apparently dedicated (according to Merola) to protecting big pharma and making sure that patients with deadly cancers don’t have access to Burzynski’s magic peptides, presumably cackling all the way to the bank to cash those big pharma checks.

Lest anyone think I am a heartless bastard, I would like it to be known that I do not like to see any creature suffer or die. I am the kind of person who, when finding a spider in the house, is likely to catch it and toss it outside. I always think, “I can’t squish the end result of 6 billion years of evolution”. Except mosquitoes. Those I squish with glee. Infection vectors can die die die die.
I like animals and hate to see them suffer unnecessarily. Like sticking them with needles. Frontal lobes are nice to have. They can let you know that pain is coming and provide preparation and compensation. Once I had a steel bar smack me on the head, opening up a six-inch cut to the bone. No, my brain was not affected, thank you very much. Everything predates the head trauma. When the ER doc numbed the scalp for sutures, he missed the last half-inch and I felt the needle. Knowing what was going on I steeled myself and let him do the last two sutures with no lidocaine, since the needle hurt only a little worse than the lidocaine injection. I have had many other unpleasant medical procedures in my 56 years but knowing what was coming and understanding why makes it easier to tolerate a needle popping into the knee joint or an abdominal drain being pulled.
Animals, and young humans, lack the ability to comprehend the what and why of pain inflicted as part of medicine. Adults can make a conscious decision to be endure pain and fool themselves into thinking it is of benefit. No pain, no gain. Animals can make no such choice.
For example consider sea turtles, who, apparently, are subjected to all sorts of nonsense at the New England Aquarium including acupuncture and laser therapy. As is obvious, I am no veterinarian, the only animal of which I have any understanding of anatomy and physiology is a human, but even with that background it is remarkable what is reported from New England. I used to say the ‘B’ students went into journalism; given the credulous reporting perhaps the standards have been lowered. They certainly have for marine biologists and veterinarians, who are evidently shortchanged in their education. (more…)
Pennsylvania legislators need to know only one thing about House Bill 612 (licensure of naturopathic “doctors”) to vote against it: As a means of “naturopathic musculoskeletal therapy” the bill would allow naturopaths to “reposition body tissues and organs.”
This is impossible. You cannot “reposition” tissues and organs of the human body by external manipulation.
Why does this tell us everything we need to know about these naturopathic doctors and why they shouldn’t be licensed in Pennsylvania? For one thing, this is no mistake a bill draftsman made in understanding what naturopathic practice includes. House Bill 612 was obviously drafted by naturopaths. That means naturopathic doctors actually believe they can “reposition” your body’s tissues and organs. And that speaks to their poor education and training. They don’t even understand basic anatomy.
For another, it tells us naturopathic doctors reject evidence-based medicine as a standard of practice. There is no evidence that this “repositioning” of organs and tissues is beneficial for any condition or disease, even if they could do it in the first place, which they can’t.
And for yet another, this certainly calls into question their understanding of the disease process and their diagnostic skills. One has to wonder exactly what health problems they think these purportedly out-of-place organs are causing. And how do they go about determining which organs are out of place and where they should go? Or when they have been successfully returned to their proper position? Again, this should raise alarming questions in the legislators’ minds about their education and training. (more…)
