The Other Anti-Vaccinationists

Those with an anti-vaccine ideology come from various starting points. There are those who just hate vaccines – because they don’t trust the system, they don’t like the idea of injecting something into their children, or they blame vaccines for their child’s illness or disorder. There is also the “mercury militia” – those who blame environmental mercury for all ills, and whose attention was drawn to vaccines through the mercury-based thimerosal connection. I wrote recently about another group – radical environmentalists who see vaccines and just another environmental exposure the government is trying to cover up.

There is another group that has been around for a while but about which I have not written before – some elements of the right-to-life group. What is their connection to vaccines? – the false belief that vaccines contain cells from aborted fetuses. Recently Lifenews published an article with the following headline: Study Suggests Link Between Autism and Use of Cells From Abortions in Vaccines. The study, of course, does nothing of the sort.

The EPA Study

LifeNews editor, Steven Ertelt, was referring to a recent EPA study published in Environmental Science Technology called Timing of Increased Autistic Disorder Cumulative Incidence. If you read the paper you will find no mention of vaccines, let alone fetal cells in vaccines. The study simply looked at databases of autism diagnosis to see if there was a point at which the increasing cumulative diagnoses was most sharp – any turning points in the data. The point of this exercise is to suggest where to look for a potential environment factor contributing to autism – because that’s what the EPA does, look for environmental exposures that are causing human disease.

A Report from the Bariatric Trenches

The American Society of Bariatric Physicians recently invited me to speak at their continuing medical education (CME) conference on obesity in Seattle. They got my name from Stephen Barrett of Quackwatch and asked if I could speak about questionable weight loss treatments like HGH, MIC (methionine, inositol and choline), and the HCG Diet. I seized the opportunity to discuss how to evaluate any medical claim, with examples from alternative medicine as well as from weight loss. My title was “Questionable Evidence for Questionable Treatments.” I talked about some of the things that can go wrong in clinical trials and why simply finding reports of positive randomized controlled trials (RCT) is not enough. I advocated rigorously science-based medicine and recommended the SBM website.

Several people came up afterwards to express their thanks and their agreement, but some of the questions from the audience were rather hostile. One man said he was a military doctor and he was using and teaching acupuncture (which I had criticized as a bad example of “tooth fairy science” in my talk). I asked for his opinion of battlefield acupuncture and he just said “No comment.” A couple of people thought science wasn’t enough and thought it was okay to prescribe questionable treatments when there was no proven effective treatment. I responded that I had no objection as long as the patient was told the facts and not given the false impression that the questionable treatment had been tested and shown to work.

I was glad for the chance to meet some of the ASBP members. I had never met a bariatric physician and was interested to learn about their practices and philosophies. I had never really thought about the fact that most obese patients had associated diseases like hypertension and diabetes, so their overall management could be very complex. I attended the whole obesity course: some of what I heard was educational, some of it was questionable, and some of it was frankly disturbing. (more…)

The complexity of cancer: A science-based view

Last week I participated in a panel discussion at NECSS with John Snyder, Kimball Atwood, and Steve Novella, who reported on the conference last Monday. What I mentioned to some of the attendees is that I had managed to combine NECSS with a yearly ritual that I seldom miss, namely the yearly meeting of the American Association for Cancer Research (AACR) meeting. There are two huge cancer meetings every year, AACR and the annual meeting of the American Society for Clinical Oncology (ASCO). AACR is the meeting dedicated to basic and translational research; ASCO, as the word “clinical” in its name implies, is devoted mainly to clinical research. Personally, being a translational researcher myself and a surgeon, I tend to prefer the AACR meeting over ASCO, not because ASCO isn’t valuable, but mainly because ASCO tends to be devoted mostly to medical oncology and chemotherapy, which are not what I do as a surgeon. Each meeting draws between 10,000 to 15,000 or even more clinicians and researchers dedicated to the eradication of cancer.

Having taken the Acela train from the NECSS meeting in New York straight to Washington, DC for the AACR meeting, I couldn’t help but think a bit about the juxtaposition of our discussion of the infiltration of quackademic medicine into medical academia with the hard core science being discussed at AACR. One session in particular at AACR highlighted what is one of the most significant differences between science-based medicine and the various forms of “alternative” medicine that we discuss here on SBM on such a regular basis. That difference, quite simply put, is the difference between the simple and the complex. “Alternative” medicine supporters often scoff at practitioners of science-based oncology, asking why we don’t have a “cure for cancer” yet—as if cancer were a single disease!—or why we haven’t made much more progress since President Richard Nixon declared “war on cancer” back in 1971. One part of the answer is that cancer is incredibly complicated. Not only is it not a single disease, but each variety of cancer is in and of itself incredibly complicated as well. To steal from Douglas Adams, cancer is complicated. You just won’t believe how vastly, hugely, mind-bogglingly complicated it is. I mean, you may think algebra is complicated, but that’s just peanuts to cancer.

NDE Update

Back in 2008 I wrote on Near Death Experiences (NDE’s). I have an interest in this topic as I have frequent exposure to near death; my wife has a predilection for watching Judge Judy. Since 2008 there have been a few studies on the topic of NDEs as researchers try and find evidence that consciousness transcends the brain, if that is what a NDE represents. I have also been ill for most of the last week and have not had the usual time to spend generating typos to drive some readers to distraction. Fortunately, I have a miracle cure that is 100% effective in resolving all my self-limited illnesses: time. It passed and with it the illness. As a result I am about 10 days behind in the commitments in my life, so this will be a shorter than usual post.

Demonizing “Big Pharma”

To be blunt up front – SBM is not apologetic about the pharmaceutical industry. We get zero funding from any company, and have no ties of any kind to “big pharma.” In today’s world I have to spend time making that clear, because despite the reality critics are free to assume and falsely claim that our message is coming straight from the bowels of hell (a.k.a. the pharmaceutical industry).

We promote science-based medicine and criticize pharmaceutical companies along with everyone else when they place other concerns ahead of scientific validity, or promote bad science, for whatever reason.

It has become fashionable, however, to not only criticize the pharmaceutical industry but to demonize them – and the term “big pharma” has come to represent this demonization. Cynicism is a cheap imitation of skepticism – it is the assumption of the worst, without careful thought or any hint of fairness.

Brain-Training Products Useless in Study

The health marketplace has a life of its own, mostly separated from science and evidence. Generally the marketplace gets a hold of an idea and runs with it, before the science is carefully worked out. Since most new ideas in science turn out to be wrong, that means most products will eventually be found to be worthless.

One such idea is that “brain training” can improve overall cognitive function – so of course now there is an industry of products which claim to train your brain. Lumosity (just to pick a random example served up by Google) claims on their website:

Brain Train
SCIENTIFICALLY DESIGNED

* Improve memory and attention
* Shown to improve cognitive function
* Neuroscience based brain training
* Train your brain today

I always enjoy the phrase “scientifically designed” or “scientifically formulated” – they are wonderful marketing phrases that invoke “science” without making any specific claims.

Nine Breakthroughs and a Breakdown

In his new book Breakthrough! How the 10 Greatest Discoveries in Medicine Saved Millions and Changed Our View of the World Jon Queijo describes what he believes are the 10 greatest discoveries. 9 of them are uncontroversial discoveries that have been on other top-10 lists, but his 10th choice is one that no other list of top discoveries has ever included. He realizes that, and even admits in his introduction that a former editor of The New England Journal of Medicine refused to review his book because there is no such thing as alternative medicine, only treatments that work and treatments that don’t. But he “respectfully disagrees.”

Hippocrates’ discovery that disease had natural causes, sanitation, germ theory, anesthesia, X-rays, vaccines, antibiotics, genetics, and treatments for mental disorders are all worthy candidates for the list. But Queijo ludicrously lists the “rediscovery of alternative medicine” as the tenth “great discovery.” He presents no evidence (because there is no evidence) that alternative medicine has “saved millions” or that it has saved anyone. He doesn’t realize that alternative medicine represents a betrayal of exactly the kind of rigorous scientific thinking and testing that led to all the other discoveries. His list of ten breakthroughs is actually a list of 9 breakthroughs and one breakdown. (more…)

Chemotherapy versus death from cancer

Editor’s Note: Having pivoted immediately (and dizzyingly) from attending NECSS and participating with John Snyder, Kimball Atwood, and Steve Novella in a panel on the infiltration of quackery into academia to heading down to Washington, DC for the AACR meeting, I’ve neglected my SBM duties a bit this week. After a packed day of talks at the AACR meeting followed by spending an evening with a friend whom I haven’t seen for a long time (complete with a trip to The Brickskeller), there’s–gasp!–no new material today. Because for some reason a decision was apparently made to cut our panel very short in order to get the conference back on schedule, we were unable to answer anywhere near as many questions from the audience as we had originally hoped, I was thinking of doing a post trying to answer a couple of the questions asked by audience members who came up to me after the panel terminated prematurely, because one of them was a particularly dicey situation. Maybe later this week. In the meantime, here’s something that I wrote about a year ago, which I tweaked a bit. It’s a very serious topic, but I think it appropriate because it discusses exactly what science-based medicine tries to prevent using evidence and what “alternative medicine” claims it can prevent based on no evidence.

I’ve written before about the Daniel Hauser case, a 13 year old boy who last year refused chemotherapy for his Hodgkin’s lymphoma, necessitating the involvement of the legal system. Cases like that of Daniel Hauser reprsent supreme “teachable” moments that–fortunately–don’t come along that often. The antivaccine movement, for instance, will be with us always (or at least, I fear, as long as I still walk this earth and beyond), but cases like that of Daniel Hauser tend to pop up only once every couple of years or even less. As tragic as they are, they always bring up so many issues that I have a hard time leaving them alone.

This time around, I wanted to touch on an issue that has come up frequently in the discussions of this case, and that’s the issue of chemotherapy. Specifically, it’s the issue of how horrible chemotherapy can be. Again, make no mistake about it, chemotherapy can be rough. Very rough. But what is often forgotten is that it can also be life-saving, particularly in the case of hematologic malignancies, where it is the primary therapy. What is also often forgotten or intentionally ignored by promoters of unscientific medicine is that doctors don’t use chemotherapy because they have some perverted love of “torturing” patients, because they’re in the pockets of big pharma and looking for cash, or because they are too lazy to find another way. They do it because, at least right now, it’s the best therapy science-based medicine has to offer, and in the case of Hodgkin’s lymphoma, for example, it’s life-saving. You can be sure that if a less harsh way were found to achieve the same results, physicians would jump all over it. Indeed, a major focuse of oncology research these days is to find less brutal regimens and improve the quality of life of cancer patients while still giving them the best shot at survival.

Homeopathy – Failing Randomized Controlled Trials Since 1835

I’m sad to say that this is the last day of World Homeopathy Awareness Week.  We’ve tried to give homeopathy its due honor, providing it the attention its practitioners clearly desire, while continuing to cover pertinent news in the world of homeopathy and providing a somewhat more sober, rational discussion of it on our homeopathy reference page.

Of course, most of this has not been news in the literal sense of the word.  There hasn’t been anything truly new in homeopathy since its invention (no, not discovery; discovery implies that something actually exists to be found) by Hahnemann in 1796.

Well, perhaps that’s not quite fair.  As our knowledge of reality (medicine, pharmacology, chemistry, physics, etc) has steadily improved, homeopathy’s plausibility has dwindled to the point of being indistinguishable from the roundest of numbers (0).  And I suppose the recent contortions of logic, abuses of legitimate science, and pure magical thinking put forth to protect homeopathy from the relentless assault of science are far more impressive than that laid out by Hahnemann.  So that’s news of a sort.

There’s also homeopathy’s long and rich tradition of abject failure in randomized controlled trials to consider.  The overwhelming mountain of evidence showing homeopathy to have no effect beyond placebo is impressive and definitive.  That’s data Hahnemann didn’t have, so that’s news too.

Each of these properly conducted studies and analyses demonstrates the scientific method’s utility to help us understand reality and protect us from our own delusions, but frankly, at this point they are about as exciting and useful as proving that the sun will rise in the east tomorrow morning.  News?  Not so much.

The dangers of opponents of science-based medicine

Michael Specter, author of Denialism: How Irrational Thinking Hinders Scientific Progress, Harms the Planet, and Threatens Our Lives, on the danger of science denial:

Given that more than half of the video is devoted to discussing vaccine denialism, supplements, and HIV/AIDS denialism, I think Spector’s talk is quite appropriate for this blog. Perhaps the best quote in Specter’s entire speech is this: “When you start down the road where belief in magic replaces evidence and science, you end up in a place where you don’t want to be.”

Unfortunately, for more and more of the population, it seems, when it comes to vaccines and “alternative” medicine that’s exactly where they’re going. They don’t want to be there, but unfortunately they won’t realize it until there there. They might not even realize it even then.

Unfortunately, society will.
