Dr. Amy Tuteur has decided to leave Science-Based Medicine

The editors and crew at SBM have an announcement that needs to be made. This morning, Dr. Amy Tuteur tendered her resignation and will therefore no longer be a blogger at SBM. Some of you might already be aware of this development because Dr. Tuteur has already announced her decision on her own blog. That is why we considered it important to post an announcement here on SBM as soon as possible.

While we are sorry to see Dr. Tuteur go and wish her well in whatever future endeavors she decides to pursue, over the last several weeks it had become clear to both the editors of SBM and Dr. Tuteur herself that, although Dr. Tuteur had routinely been able to stimulate an unprecedented level of discussion regarding the issues we at SBM consider important, SBM has not been a good fit for her and she has not been a good fit for SBM. Over the last few days mutual efforts between the editors and Dr. Tuteur to resolve our differences came to an impasse. Unfortunately for all parties, that impasse appeared to be unresolvable and resulted in Dr. Tuteur’s decision to leave SBM.

As a result of Dr. Tuteur’s departure, we will be adjusting the posting schedule in order to cover her normal Thursday slot. Final decisions have not been made yet, but we expect that every weekday will continue to be covered, with at least one post per weekday.

The fall of Andrew Wakefield

I must admit, I never saw it coming.

At least, I never saw it coming this fast and this dramatically. After all, this is a saga that has been going on for twelve solid years now, and it’s an investigation that has been going on at least since 2004. Yes, I’m referring to that (possibly former) hero of the anti-vaccine movement, the man who is arguably the most responsible for suffering and death due to the resurgence of measles in the U.K. because of his role in frightening parents about the MMR vaccine.

Rom Houben: Not communicating through facilitated communication

The news is finally filtering out to the rest of the world.

As Steve Novella and my good buddy pointed out a few days ago (and as Steve pointed out in an interview on NPR), Dr. Steven Laureys admitted that Rom Houben, the unfortunate victim of a car crash that left him in what had been diagnosed as a persistent vegetative state, was in fact not able to communicate through the woo known as facilitated communication. This came as no surprise to anyone who has followed FC over the years. In fact, what had come as a surprise is that Dr. Laureys could have been so easily taken in by pseudoscience that had been so thoroughly debunked in the 1990s. To his credit, though, after a period of initially stubbornly defending FC, he relented and allowed objective testing, and the result was predictable. It took a few days, but the English language world is learning of the failure of FC in Houben’s case:

The sceptics said it was impossible – and it was. The story of Rom Houben of Belgium, which made headlines worldwide last November when he was shown to be “talking”, was today revealed to have been nothing of the sort.

Dr Steven Laureys, one of the doctors treating him, acknowledged that his patient could not make himself understood after all. Facilitated communication, the technique said to have made Houben’s apparent contact with the outside world possible, did not work, Laureys declared.

“We did not have all the facts before,” he said. “To me, it’s enough to say that this method doesn’t work.” Just three months ago the doctor was proclaiming that Houben had been trapped in his own body, the victim of a horrendous misdiagnosis, and only rescued from his terrible plight thanks to medical advances.

What was not reported is that skeptics were involved in the testing of Rom Houben. I recently received a statement from the Belgian Skeptics (SKEPP):

The Winkler County nurse case and the problem of physician accountability

A MISCARRIAGE OF JUSTICE THAT HAD A (SORT OF) HAPPY ENDING

Back in September and then again last week, I wrote briefly (for me) about an incident that I considered to be a true miscarriage of justice, namely the prosecution of two nurses for having reported the dubious and substandard medical practices of a physician on the staff of Winkler County Hospital in Kermit, Texas. The physician’s name is Dr. Rolando Arafiles, and he happened to be a friend of the Winkler County Sheriff, Robert Roberts, who also happened to have been a patient of Dr. Arafiles and very grateful to him for having saved his life. The nurses, Anne Mitchell and Vickilyn Galle, were longtime employees of Winkler County Hospital, a fifteen bed hospital in rural West Texas. Although some of you may have seen extensive blogging about this before, I thought it very important to discuss some of the issues involved on this blog. Moreover, there is an aspect to this case that the mainstream media reporting on it has missed almost completely, as you will see. Finally, this case showed me something very ugly about my profession, not just because a doctor tried to destroy the lives of two good nurses through his connections to the good ol’ boy network in Winkler County

Let’s recap what happened, a story that reached its climax last Thursday. In 2008, Dr. Arafiles joined the staff of Winkler County Hospital (WCH). It did not take too long for it to become apparent that there were serious problems with this particular doctor. Mitchell and Galle, who worked in quality assurance were dismayed to learn that Dr. Arafiles would abuse his position to try to sell various herbal remedies to patients in the WCH emergency room and the county health clinic and to take supplies from the hospital to perform procedures at a patient’s home rather than in the hospital. No, it wasn’t the fact that Dr. Arafiles recommended supplements and various other “alt-med” remedies, it’s that he recommended supplements and various other “alt-med” remedies that he sold from his own business–a definite no-no both ethically and, in many states, legally. Mitchell reported her concerns to the administration of WCH, which did pretty much absolutely nothing. Consequently, on April 7, 2009, Mitchell and Galle anonymously reported their concerns to the Texas Medical Board (TMB). In June, WCH fired the two nurses without explanation.

The Dietary Supplement Safety Act of 2010: A long overdue correction to the DSHEA of 1994?

BACKGROUND: A BAD, BAD LAW

One of the themes of this blog has been how, over the last couple of decades, the law has been coopted by forces supporting “complementary and alternative” medicine (CAM) in order to lend legitimacy to unscientific and even pseudoscientific medical nonsense. Whether it be $120 million a year being spent for the National Center for Complementary and Alternative Medicine (NCCAM) or attempts to insert provisions mandating that insurers in the government health care co-ops that would have been created by President Obama’s recent health care reform initiative (which at the moment seems to be pining for the fjords, so to speak), the forces who do not want pesky things like regulation to interfere with their selling of pseudoscience have been very successful. Arguably the crown jewel of their legislative victories came in 1994, when the Dietary Supplement Health and Education Act (DSHEA) was passed. Demonstrating that pseudoscience is a bipartisan affair, the DSHEA was passed, thanks to a big push from the man who is arguably the most powerful supporter of quackery in government and the man most responsible for the creation of the abomination that is NCCAM, Senator Tom Harkin (D-IA), along with his partner in woo, Senator Orrin Hatch (R-UT). It should be noted that Harkin happens to be the recipient of large contributions from supplement manufacturer Herbalife, demonstrating that big pharma isn’t the only industry that can buy legislation related to health.

Dr. Lipson has discussed the DSHEA before (calling it, in his own inimitable fashion, a “travesty of a mockery of a sham“) as has a certain friend of mine. Suffice it to say that the DSHEA of 1994 is a very bad law. One thing it does is to make a distinction between food and medicine. While on its surface this is a reasonable distinction (after all, it wouldn’t make a lot of sense to hold food to the same sorts of standards to which drugs are held), as implemented by the DSHEA this distinction has a pernicious effect in that it allows manufacturers to label all sorts of botanicals, many of which with pharmacological activity, as “supplements,” and supplements, being defined as food and not medicine, do not require prior approval by the FDA before marketing:

The legal establishment of Winkler County, Texas conspires to punish whistle blowing nurses

On Science-Based Medicine, several of us have at various times criticized state medical boards for their tolerance of unscientific medical practices and even outright quackery. After all, Dr. Rashid Buttar still practices in North Carolina and the medical board there seems powerless to do anything about it. However, state medical boards have other functions, one of which is to respond to complaints of unethical and dubious behavior about doctors. Key to this function is protection; i.e., if someone reports a doctor, that person needs to be sure that the state will protect her from retaliation from that doctor of the hospital. About five months ago, I reported a true miscarriage of justice, the sort of thing that should never, ever happen. In brief, it was the story of two nurses who, disturbed at how a local doctor was peddling his dubious “herbal” concoctions in the emergency room of the local hospital when he came in to see patients, reported him to the authorities. Moreover, they had gone up the chain of command, first complaining to hospital authorities. After nothing happened for months, they decided to report the physician, Dr. Rolando Arafiles, to the Texas Medical Board because they honestly believed that this physician was abusing his trust with patients and behaving unethically by improperly hawking herbal supplements that he was selling in the rural health clinic and the emergency room of Winkler County Memorial Hospital.

Even though under whistleblower laws the identities of these nurses should have been kept secret, after he learned that a complaint had been filed against him Dr. Arafiles went to his buddy the Winkler County Sheriff Robert L. Roberts, who left no stone unturned in trying to find out who had ratted out Dr. Arafiles:

To find out who made the anonymous complaint, the sheriff left no stone unturned. He interviewed all of the patients whose medical record case numbers were listed in the report and asked the hospital to identify who would have had access to the patient records in question.

At some point, the sheriff obtained a copy of the anonymous complaint and used the description of a “female over 50″ to narrow the potential complainants to the two nurses. He then got a search warrant to seize their work computers and found a copy of the letter to the medical board on one of them.

The result was this:

In a stunning display of good ol’ boy idiocy and abuse of prosecutorial discretion, two West Texas nurses have been fired from their jobs and indicted with a third-degree felony carrying potential penalties of two-to-ten years’ imprisonment and a maximum fine of $10,000. Why? Because they exercised a basic tenet of the nurse’s Code of Ethics — the duty to advocate for the health and safety of their patients.

On Saturday, the New York Times reported on the story, as there have been significant developments since August. Specifically, although the charges against one of the nurses has been dismissed, Anne Mitchell, RN, is going to stand trial beginning today:

The General Medical Council to Andrew Wakefield: “The panel is satisfied that your conduct was irresponsible and dishonest”

BACKGROUND

In my not-so-humble opinion, the very kindest thing that can be said about Andrew Wakefield is that he is utterly incompetent as a scientist. After all, it’s been proven time and time again that his unethical and scientifically incompetent “study” that was published in The Lancet in 1999 claiming to find a correlation between vaccination with MMR and autistic regression in autistic children with bowel symptoms was at best dubious science and at worst fraudulent. For one thing, as investigative journalist Brian Deer found, Wakefield was in the pocket of trial lawyers, who were interested in suing vaccine manufacturers, to the tune of £435,643 in fees, plus £3,910 expenses beginning even before his infamous “study” started accruing patients. Even though the study itself used the typical careful and relatively neutral language that we all expect from scientists, Wakefield himself was not nearly so circumspect. In a press conference announcing the Lancet study, he said:

He told journalists it was a “moral issue” and he could no longer support the continued use of the three-in-one jab for measles, mumps and rubella.

“Urgent further research is needed to determine whether MMR may give rise to this complication in a small number of people,” Dr Wakefield said at the time.

And so began one of the most contentious health stories of this generation.

Wakefield’s Lancet paper, even interpreted as sympathetically as possible, concluded nothing that justified such language. Yet his rhetoric, along with sensationalistic and credulous British journalists, ignited a firestorm of fear over the MMR that has not yet subsided now, over a decade later. Vaccination rates plummeted in the UK, and measles, a disease once thought to be under control, has surged back and become endemic again. It is a feat that Jenny McCarthy and Jim Carrey appear to be trying to replicate right here in the U.S. with their wonderfully Orwellian-named Green Our Vaccines activism and ceaseless promotion of anti-vaccine messages.

More recently, at the Autism Omnibus hearings, we learned from a world expert in the polymerase chain reaction, Dr Stephen Bustin, that the techniques used in the laboratory running PCR on the clinical specimens from Wakefield’s clinical trial were so shoddy, so devoid of routine controls necessary in any PCR experiment, that the measles sequences reported as amplified in Wakefield’s followup to his Lancet study were false positives derived from plasmids with measles sequences in them contaminating the laboratory. Then, in late 2008, Mady Hornig and colleagues at Columbia University published an attempted replication of Wakefield’s study. They failed. There was no association between vaccination with MMR and autistic regression, nor could Hornig find any evidence that measles in the gut was any more common in the autistic children studied than in the neurotypical controls. This study was particularly devastating to Wakefield because it was carried out by a researcher who had previously been sympathetic to the myth that vaccines cause autism, as evidenced by her infamous “rain mouse” study and, even more close to home, using the same laboratory that had performed Wakefield’s PCR, which had apparently cleaned up its act in the years following its work on Wakefield’s specimens.

When it comes to the science, there is no doubt. No reputable scientist has been able to replicate Wakefield’s findings, and there is a remarkable convergence and agreement of findings of major studies looking for a correlation between MMR vaccination and autism: There ain’t one. Indeed, closing out 2009 was the publication of yet another study that failed to find any correlation between MMR and autism, or, as I put it at the time, yet another nail in the coffin of the myth that the MMR vaccine causes autism. Andrew Wakefield’s repeated claims that the MMR can cause or “trigger” autism in some children is deader than dead as a scientific hypothesis and without a basis in scientific or clinical evidence. True, Wakefield tried to counter with a horribly unethical and badly designed primate study that seemed custom-designed to be used in court rather than in the court of scientific inquiry. It didn’t help and only made Wakefield’s Thoughtful House, Wakefield’s Fortress of Solitude in Texas to which he retreated in the wake of the revelations about his conduct, look even worse. Even a credulously “balanced” TV story by NBC news and Matt Lauer couldn’t hide the dubiousness nature of what goes on there.

Of course, while the science refuting Wakefield’s pseudoscience and evidence showing Wakefield to be incompetent and unethical continued to roll in, a little less than a year ago, it got even worse for him. Brian Deer reported that Wakefield very well may have engaged in scientific fraud in the “research” (and I do use the term loosely) that led to the publication of his Lancet paper in 1999. Through it all, the General Medical Council began an inquiry into whether Andrew Wakefield behaved unethically in the “research” that resulted in his 1999 Lancet report. It should be pointed out that the investigation of the GMC began before Deer’s latest revelation of potential fraud; rather it was far more concerned with how Wakefield ran his study and recruited patients. Nonetheless, the revelations nearly a year ago about Wakefield’s playing fast and loose with research methodology could not help but contribute to the sense that the Good Ship Wakefield had been torpedoed below the water line and was taking on water fast.

As the investigation and hearings wound on seemingly endlessly for two and a half years, Wakefield’s supporters intermittently waged an increasingly histrionic and ridiculous propaganda offensive to try to preemptively discredit the GMC’s findings. As it became clear that finally after all this time the GMC was on the verge of announcing its ruling, I noticed that the anti-vaccine crank blog Age of Autism was ramping up an increasingly bizarre and unhinged last minute propaganda campaign, complete with reposting a hilariously inapt post by Mark Blaxill comparing Wakefield to Galileo and the GMC to the Inquisition, complete with references to Stalin and Mao (I suppose I should be relieved that Blaxill refrained from playing the Hitler card); a defense of “that paper” by Wakefield himself; claims that parent witnesses had been “silenced” at the GMC hearings; and a whole series of posts by John Stone trying to discredit the GMC.

And then on Thursday, the GMC ruled.

On the “individualization” of treatments in “alternative medicine”

One of the claims most frequently made by “alternative medicine” advocates regarding why alt-med is supposedly superior (or at least equal) to “conventional” medicine and should not be dismissed, regardless of how scientifically improbable any individual alt-med modality may be, is that the treatments are, if you believe many of the practitioners touting them, highly “individualized.” In other words, the “entire patient” is taken into account with what is frequently referred to as a “holistic approach” that looks at “every aspect” of the patient, with the result that every patient requires a different treatment, sometimes even for the exact same disease of very close to the same severity. Indeed, as I have described before, a variant of this claim, often laden with meaningless pseudoscientific babble about “emergent systems,” is sometimes used to claim that the standard methods of science- and evidence-based medicine are not appropriate to studying the efficacy of alternative medicine. Of course, this is, in nearly all cases, simply an excuse to dismiss scientific studies that fail to find efficacy for various “alt-med” modalities, but, even so, it is a claim that irritates me to no end, because it is so clearly nonsense. As Harriet Hall pointed out, alt-med “practitioners” frequently ascribe One True Cause to All Disease, which is about as far from “individualization” as you can get, when you come right down to it. More on that later.

A couple of years ago, before I became involved with this blog, I was surprised to learn that even some advocates of alt-med have their doubts that “individualization” is such a great strength. I had never realized that this might be the case until I came across a post by naturopath Travis Elliott, who runs a pro-alt-med blog, Dr. Travis Elliott and the Two-Sided Coin, entitled The Single Most Frustrating Thing About (Most) Alternative Medicine. In this article, Elliott referred to a case written up by a fellow naturopath, who used an anecdote about the evaluation and treatment plan by a naturopath of a pregnant woman with nausea to show what is supposedly the “unique power of our medicine.” Unexpectedly (to me at least at the time), Elliott did not quite see it that way:

Abortion and breast cancer: The manufactroversy that won’t die

Editor’s note: Given the controversial nature of the topic, I think it’s a good time to point out my disclaimer before this post. Not that it’ll prevent any heated arguments or anything…

The Science-Based Medicine blog was started slightly over two years ago, and this is a post I’ve wanted to do since the very beginning. However, since January 2008, each and every time I approached this topic I chickened out. After all, the topic of abortion is such a hot button issue that I seriously questioned whether the grief it would be likely to cause is worth it. (Take the heat generated any time circumcision is discussed here and ramp it up by a factor of 10.) On the other hand, there is so much misinformation out there claiming a link between abortion and the subsequent development of breast cancer when the data simply don’t support such a link, and the name of this blog is Science-Based Medicine. Why should I continue to shy away from a topic just because it’s so religiously charged? More importantly, in my discussion how can I focus attention on the science rather than letting the discussion degenerate into the typical flamefest that any discussion of abortion on the Internet (or anywhere else, for that matter) will almost inevitably degenerate into. Indeed, such discussions have a depressing near-inevitability of validating Godwin’s law not once but many times — usually within mere hours, if not minutes.

My strategy to try to keep the discussion focused on the science will be to stay silent about my own personal opinions regarding abortion and, other than using it to introduce my trepidation about discussing the topic, the religious and moral arguments that fuel the controversy. That’s because the question of whether abortion is the murder of a human being, merely the removal of a lump of tissue, or somewhere in between is a moral issue that, at least as far as I’m concerned, can’t ever be definitively answered by science. That is why it is not my purpose to sway readers towards any specific opinion regarding the morality of abortion. Indeed, I highly doubt that any of our readers care much about my opinions on the matter. On the other hand, I would hope that I’ve built up enough trust over the last two years that our readers will be interested in my analysis of the existing data regarding something another related issue. It is my purpose to try to dispel a myth that is not supported by science, specifically the claim that elective abortion is causes breast cancer or is a very strong risk factor for its subsequent development. That is a claim that can be answered by science and, for the most part, has been answered by science with a fairly high degree of certainty. Despite the science against it, the medical myth that abortion causes breast cancer or vastly increases the risk of it is, like the myth that vaccines cause autism, a manufactroversy that won’t die, mainly because it is largely fueled by religious beliefs that are every bit as immune to science as the ideological beliefs that drive the antivaccine movement.

Be careful what you wish for, Dr. Dossey, you just might get it

If there’s one thing about the so-called “complementary and alternative medicine” (CAM) movement that I’ve emphasized time and time again, it’s that its adherents have a definite love-hate relationship with science. They hate it because it is the single greatest threat to their beliefs system and the pseudoscience that underlies it. At the same time, they crave the legitimacy that science confers. They crave it not because they have any great love for science. Quite the contrary. It is simply that they recognize that science actually delivers the goods. Of course, they believe that they deliver the goods too, but they come to this belief not through science but rather through all the cognitive shortcomings and biases to which humans are prone, such as confusing correlation with causation, confirmation bias, not recognizing regression to the mean, and being fooled by the placebo effect. Whether it’s through a misunderstanding of science or less innocent reasons, they go to great lengths to torture it into superficially appearing to support their claims through a combination of cherry-picking of studies that seem to support them and misrepresenting ones that don’t, discussions of which abound right here in this very blog.

The other thing I’ve emphasized about the CAM movement is that, even more than scientific credibility, they crave legitimacy. To them, however, science is but one pathway to legitimacy, because, unlike practitioners of science-based medicine, they are more than willing to bypass science to obtain the legitimacy–or at least the appearance of the legitimacy–they so crave. If it means doing an end run around science by trying to hijack the Obama health insurance reform bill that is currently being negotiated to resolve the differences between the Senate and House versions, so be it. Indeed, earlier this year, I described how Senator Tom Harkin has tried to promote CAM through the National Center for Complementary and Alternative Medicine (NCCAM) and trying to insert provisions into the bill that would mandate that government-subsidized insurance exchanges pay for CAM. Meanwhile, prominent CAM advocates have been carpet-bombing the media with dubious arguments in support of CAM, as in when Deepak Chopra, Rustum Roy, Dean Ornish, and Andrew Weil teamed up in different combinations to promote the idea that CAM is all about “prevention” and that science-based medicine, in all its reductionistic evil, is nothing more than pushing pills.

They’re at it again.
