With some degree of sadness I recently “outed” a former co-resident of mine who has turned to the dark side and begun putting money-making before truth and science. Without any clear evidence of benefit beyond placebo, platelet-rich plasma (PRP) is now being marketed aggressively as a cure-all for sports injuries. And at about $300 per injection (the NYT reports $2000/treatment), there’s plenty of money to be made.
Like the fake “stem cell” clinics in Russia (where, according to Sanjay Gupta’s recent book, Chasing Life, a person’s fat cells are harvested, washed, and re-injected into their blood stream), PRP also involves injection of autologous body fluids. Essentially, a small amount of blood is drawn from the patient, centrifuged, and the plasma supernatant is then injected directly into tendons and/or joints. After a series of 3 injections (one/month), most sports injuries are “cured.” Of course, most injuries would heal themselves in three months anyway. (more…)
I’m taking this opportunity to introduce a new blog to the SBM audience, and to draw yet more attention to the growing and dangerous trend of parental vaccine refusal. So, please take a momentary break from your perusal of this most esteemed font of knowledge, and point your browser to Gotham Skeptic.
A recent study published in the journal Complementary Therapies in Medicine shows no benefit from copper or magnetic bracelets for symptomatic treatment of arthritis. While this is a relatively small study, it highlights the lack of evidence to support this billion dollar plus industry.
The study is a double-blind, controlled crossover study involving 45 subjects with osteroarthritis. Each subject wore one of four bracelets – copper, two types of magnetic bracelet, and one demagnetized, in random order each for 16 weeks. It showed no difference among the four groups.
This is only the second published controlled trial looking at copper bracelets for arthritis. The first is from 1976 and showed some benefit. Then there are no published studies (just reviews and comments) for the next 33 years, until this current study.
The past two months have been my first time working in the hospital, as a third-year medical student in my Internal Medicine clerkship. It’s been exciting not only to see how medicine works but to be a part of the action! It really is striking to see the dramatic increases in proficiency and confidence with each stage of the training. From junior student to acting intern to intern to resident to chief resident and eventually to attending, each year brings both more responsibility and more competence. Importantly, physicians-in-training also get very efficient in seeking out and communicating information. Just like SBM editors read widely and blog prolifically whereas I struggle to put together one post a month, experienced clinicians have responsibility for dozens of patients at a time whereas I feebly tag along with one or two each day. Watching my elders on the medical team, I feel excited about how much smarter and more effective I will become as I progress through my training.
Anyway, I want to share an interesting sight in my hospital last month. There were three 3-foot posters on tripods prominently displayed in the hospital lobby, in the cafeteria, and in other public places. The first one read: (more…)
A recent study is being cited as support for homeopathy. For instance, the Homeopathy World Community website says
Luc Montagnier Foundation Proves Homeopathy Works.
Dana Ullman cites it in the comments to this blog
And I assume that you all have seen the new research by Nobel Prize-winning virologist Luc Montagnier that provides significant support to homeopathy.
Nope. Sorry, guys. It doesn’t. In fact, its findings are inconsistent with homeopathic theory.
The study has nothing whatsoever to say about homeopathy. Its abstract concludes:
This opens the way to the development of highly sensitive detection system for chronic bacterial infections in human and animal diseases.
Homeopaths are grasping at straws when they cite this study. It involved dilution and agitation: that’s the only possible hint of anything homeopathic and it is nothing but a false analogy. (more…)
We’ve often castigated the press and mainstream media for getting it so very, very wrong on the issue of vaccines and autism and its all-too-often credulous treatment of the anti-vaccine movement. That’s very important. However, it’s also equally important to recognize mainstream media outlets when they get it so very, very right. That’s why, with minimal fanfare, I’m simply going to refer you to an article in WIRED Magazine entitled An Epidemic of Fear: How Panicked Parents Skipping Shots Endangers Us All by Amy Wallace. I particularly like Wallace’s calling out some prominent anti-vaccine activists, such as Jenny McCarthy, Jim Carrey, Don Imus, and Robert F. Kennedy, Jr.
Bravo, Ms. Wallace. Bravo, WIRED.
Go. Read. While you’re at it, you might want to lend some tactical air support to the cause of science and reason in the comments section. As they always do, the anti-vaccine kooks have already descended.
Every so often, as the health care reform initiative spearheaded by the Obama Administration wends its way through Congress (or, more precisely, wend their ways through Congress, given that there are multiple bills coming from multiple committees in both Houses), I’ve warned about various chicanery from woo-friendly legislators trying to legitimize by legislation where they’ve failed by science various “alternative” medicine practices. This began much earlier this year, when I pointed out how Senator Tom Harkin (D-IA) invited the Four Horsemen of the Woo-pocalypse to the Senate to testify. These included Dr. Andy Weil, Director, Arizona Center for Integrative Medicine, University of Arizona, Vail, AZ; Dr. Dean Ornish, Founder and President, Preventive Medicine Research Institute, Sausalito, CA; Dr. Mark Hyman, Founder and Medical Director, The UltraWellness Center, Lenox, MA; Dr. Mehmet C. Oz, Director, Cardiovascular Institute and Complementary Medicine Program, New York-Presbyterian Hospital, New York, NY. This occurred after Harkin had famously complained about the National Center for Complementary and Alternative Medicine, the Center in the NIH that he, more than anyone else, had created, because it had not validated enough quackery. (Yes, I know he didn’t use those words, but that was what he had done.) Most recently, Harkin tried to insert language that would mandate that the government and health insurers pay for quackery, as long as it was from licensed practitioners. Given that some states license naturopaths and even “homeopathic physicians,” such an amendment, if it stayed in place, would open the way for paying for all manner of nonscientific quackery.
However, there is another bit of chicanery that legislators are pulling, this time with the Senate version of the bill, that I have been made aware of by Rita Swan of CHILD and fellow SBM blogger Kimball Atwood. This time, the threat is religious, with Senators trying to insert measures into the health care reform initiatives that will pay for “religious” treatments, such as Christian Science prayer. Indeed, one of these, S.1679, entitled Affordable Health Choices Act requires the government or private party insurers to pay for faith-based therapies:
It’s rather amazing how sometimes the best laid plans of mice and men (and bloggers) come to naught. I had planned on doing a followup post to my previous post about the cancer quackery known as the German New Medicine by discussing a particularly nasty French variant of it. Unfortunately (or fortunately, depending upon your point of view), events conspired to move my blogging ire towards another target, particularly since I had addressed this isse before. Specifically, I’m talking about 2009 Recipient of the Richard Dawkins Award, comedian and HBO talk show host Bill Maher.
As you may recall, about a month ago, I wrote a rather long post (par for the course for me, I know) detailing ad nauseam how Bill Maher not only embraces germ theory denialism, anti-vaccine nonsense, and alternative medicine, in particular his apparent belief that “aggregate toxicity” or the typical unnamed “toxins” that alternative medicine mavens are so fond of blaming most disease on or, as Maher likes to call it, the “poisons” that we are eating and otherwise exposed to every day, but has been preaching this pseudoscience since at least 2005. Maher then followed this up a mere week before receiving his award named after a famous scientist with a hideously irrational promotion of cancer quackery. At that point, I thought I was done with the topic, at least as far as this particular blog goes (others know that elsewhere I’ve not been so quiet). At least, I had intended not to deal with this again on SBM.
Unfortunately, Bill Maher had other ideas. This is the perfect description for how I felt having to blog about this again:
Yes, it fits, particularly after Maher Tweeted to his fans:
If u get a swine flu shot ur an idiot.
Dr. Weil is often seen as the smiling “mainstream” of alternative medicine. He’s a real doctor (unlike, say, Gary Null), and much of what he advocates is standard and uncontroversial nutritional advice. But Weil illustrates the two biggest problems with so-called alternative medicne: once you’ve decided science is dispensible, the door is open to anything, no matter how insane; and no matter how altruistic you may start, sooner or later you start selling snake oil. Most doctors out there are working hard to help their patients prevent and overcome disease use the available evidence. Others decide that science is too constraining and start practicing at the periphery of knowledge, throwing plausibility and ethics to the wind.
The fact that Weil claims to donate to charity all of his ill-gotten gains does not mitigate the harm he causes.
The flu pandemic has been challenging to all of us who practice medicine. We try to keep up day to day with the latest numbers, evidence, and best practices, while trying not to worry about getting ill. And since the vaccine isn’t widely available yet, we also worry about our family’s health. So we go about our work every day, wearing masks when appropriate and washing hands frequently. If the numbers reach a certain threshold, we will implement sophisticated pandemic plans.
All of that is rather hard, though, so perhaps we should just throw caution to the wind and start selling flu snake oil just like the smiling Dr. Weil.
The FDA and FTC have let Weil know in very clear terms that his fake flu remedies are being marketed illegally. Weil has taken the site down, but here’s a relevant screen shot.
Oh Canada. Look over here. Not there. Not at the press release. Look here. A real study. Published. With methodologies you can evaluate. Something you can sink your teeth into to help guide policy decisions. You know, published epidemiology. Science.
Its called “Partial protection of seasonal trivalent inactivated vaccine against novel pandemic influenza A/H1N1 2009: case-control study in Mexico City.” and published on line in the BMJ on October 6th.
Are you aware of….Oh, Canada, pay attention, your eyes are wandering.
