In hopes of joining the SBM movement as medical students, we wanted to take aim at a topic that has yet been finely dissected a la Novella or logorrheicly dismembered a la Gorski. Having realized that a fellow medical student, Tim Kreider, is already addressing integrative medicine on campus, we decided that we would attempt to find a controversial topic that has yet to be addressed on SBM. A serendipitous question from a friend sent us on a mission to explore the pseudo-scientific underbelly of the web and science-based rationale of the claim that vitamin C can induce abortion.
The World Wide Web is a stranger place than we can ever imagine. Most users are aware that they can’t believe everything they read on the Internet, yet they often feel like Sherlock Holmes when they find an esoteric and isolated clue to their own unique health puzzle. Recently, we were asked if there was a connection between vitamin C, menstruation and abortion. We were caught off guard by the question, finding it such a strange connection to make. The story, it seems, is that our friend had come down with a cold and taken mega doses of vitamin C to stave it off (another false belief, but not the subject here). A couple of days later her menses began and she was surprised since it was 4 days earlier than normal. She of course turned to Dr. Google and was quickly provided with numerous sources indicating that indeed, vitamin C would induce the start of a menstrual cycle and can even act as a “natural” abortefacient and a substitute for the ‘morning after’ pill. Being a bit more keen than your average Dr. Google user, she was surprised and continued searching, trying to find evidence to contradict these claims. Alas, she found nothingexcept more sites parroting and corroborating the claim. Then she realized she knew a couple of medical students and asked us what we thought. Our literature review turned up a slew of websites using the standard repertoire of trite pseudo-scientific tactics. Any attempt to find a credible source, validated claim, or independent consensus proved futile.
Science is a philosophy, a technology, and an institution. It is a human endeavor- our collective attempt to understand the world around us, not something that exists solely in the abstract. All of these aspects of science have be progressing over the past decades and centuries, as we refine our concepts of what science is and how it works, as we develop better techniques, and organize and police scientific activities more effectively. The practice of science is not relentlessly progressive, however, and there are many regressive forces causing pockets of backsliding, and even aggressive campaigns against scientific progress.
So-called complementary and alternative medicine (CAM) is one such regressive force. It seeks to undermine the concepts, execution, and institutions of medical science in order to promote sectarian practices and ideological beliefs. Examples of this are legion, exposed within the pages of this blog alone. I would like to add another example to the pile – the recent defense of homeopathy by Dana Ullman in the Huffington Post (names which are already infamous among supporters of SBM).
In a piece titled: Homeopathy for Radiation Poisoning, Ullman demonstrates yet again the pseudoscientific aspects of homeopathy and its proponents. The primary principle that is abused by Ullman this time is the need for scientists to carefully define their terms and concepts. Scientific concepts should be defined as carefully, precisely, and consistently as possible. Squishy concepts are very difficult to deal with in science – but are the bread and butter of pseudoscience.
The word “frequency” ranks right up there with “quantum” and “energy” as a pseudoscientific buzzword. It is increasingly prevalent in product advertisements and in CAM claims about human biofields and energy medicine. It doesn’t mean what they think it means.
I have written about Power Balance products, the wristbands and cards that allegedly improve sports performance through frequencies embedded in a hologram. They amount to nothing but a new version of the old rabbit’s foot carried for superstition and their sales demonstrations fool people with simple musculoskeletal tricks. I addressed their ridiculous claims (including “We are a frequency”). I pointed out that
The definition of frequency is “the number of repetitions of a periodic process in a unit of time.” A frequency can’t exist in isolation. There has to be a periodic process, like a sound wave, a radio wave, a clock pendulum, or a train passing by at the rate of x boxcars per minute. The phrase “33⅓ per minute” is meaningless: you can’t have an rpm without an r. A periodic process can have a frequency, but an armadillo and a tomato can’t. Neither a periodic process nor a person can “be” a frequency.
I’m not infrequently asked why the myth that vaccines cause autism and other anti-vaccine myths are so stubbornly resistant to the science that time and time again fails to support them. Certainly useful celebrity idiots like Jenny McCarthy are one reason. So, too, are anti-vaccine propaganda websites and blogs such as Age of Autism and anti-vaccine organizations like Generation Rescue, the National Vaccine Information Center, and SafeMinds and the organizations that publish them. However, these are clearly not the only reason. Alone, these people and organizations are in general quite rightly viewed as fringe, although they are very popular among the anti-vaccine movement. It is when such groups find a willing conduit for their pseudoscience in the “mainstream media” that they see the opportunity to attain a degree of seeming respectability that they can’t achieve on their own based on science. Worse, when mainstream news organizations or reporters fall for the pseudoscience claiming that vaccines cause autism, they contribute to the persistence of this myth outside the activist core of the anti-vaccine movement in the public at large.
In the past, anti-vaccine activists tried to accomplish this with the help of formerly respectable journalists such as David Kirby and Dan Olmsted, the former of whom wrote Evidence of Harm: Mercury in Vaccines and the Autism Epidemic: A Medical Mystery and the latter of whom wrote and promoted the Age of Autism series when he was an editor at UPI. However, although Kirby was never really that prominent or trusted, Olmsted was an editor of UPI. Now that he’s given up his UPI gig to become full time editor of AoA and to team up with Mark Blaxill to write a book (Age of Autism: Mercury, Medicine and a Manmade Epidemic) that regurgitated all the old misinformation about thimerosal and autism in a way that’s so 2005, Olmsted’s lost all credibility as a serious reporter. That’s a good thing.
The bad thing is that he has a replacement. Or at least so it would appear.
Steven Salzberg, a friend of this blog and Director of the Center for Bioinformatics and Computational Biology at the University of Maryland, is on the editorial boards of three of the many journals published by BioMed Central (BMC), an important source of open-access, peer-reviewed biomedical reports. He is disturbed by the presence of two other journals under the BMC umbrella: Chinese Medicine and BMC Complementary and Alternative Medicine. A couple of days ago, on his Forbes science blog, Dr. Salzberg explained why. Here are some excerpts:
The Chinese Medicine journal promotes, according to its own mission statement, studies of “acupuncture, Tui-na, Qi-qong, Tai Chi Quan, energy research,” and other nonsense. Tui na, for example, supposedly “affects the flow of energy by holding and pressing the body at acupressure points.”
Right. What is this doing in a scientific journal?… I support BMC…But their corporate leaders seem to care more about expanding their stable than about maintaining the integrity of science. Chinese Medicine simply does not belong in the company of respectable scientific journals.
Forming a scientific journal whose goal is to validate antiquated, unproven superstitions is simply not science, whatever the editors of Chinese Medicine claim.
BMC should be embarrassed to be publishing journals that promote anti-scientific theories and otherwise muddy the literature. By supporting these journals, they undermine the credibility of many excellent BMC journals. They should cut these journals loose.
