The trouble with Dr. Oz

UPDATE 4/27/2011: Here’s the online video of Dr. Novella’s appearance on The Dr. Oz Show:

  1. Controversial Medicine: Alternative Health, Part 1
  2. Controversial Medicine: Alternative Health, Part 2
  3. Controversial Medicine: Alternative Health, Part 3

Welcome, Dr. Oz viewers!

As managing editor of the Science-Based Medicine (SBM) blog, I am writing this post because our founder and exective editor Dr. Steven Novella was invited to be on The Doctor Oz Show. Later today, the episode in which he will appear will air in most of your local markets, and we wanted to make sure that any Dr. Oz viewer who sees the segment and as a result is intrigued (or angered) enough to wonder what it is that we are all about will have a convenient “primer,” so to speak, on the problem with Dr. Oz from a science-based perspective. In other words, who are these obnoxious upstart bloggers who are so critical of Dr. Oz are and, far more importantly, exactly why are we so critical? What is science-based medicine, anyway?

On to some of the answers!

The curious case of Poul Thorsen, fraud and embezzlement, and the Danish vaccine-autism studies

If there’s one thing about the anti-vaccine movement, it’s all about the ad hominem attack. Failing to win on science, clinical trials, epidemiology, and other objective evidence, with few exceptions, anti-vaccine propagandists fall back on attacking the person instead of the evidence. For example, as I’ve noted numerous times, Paul Offit has been the subject of unrelenting attacks from Generation Rescue and other anti-vaccine groups, having been dubbed “Dr. Proffit” and accused of being so in the pocket of big pharma that he’ll do and say anything for it. I personally have been accused by Jake Crosby of a conflict of interest that isn’t, based on conspiracy mongering and an utterly brain dead argument (which is much like every other argument Jake likes to make on this issue). Steve Novella, Paul Offit, Amy Wallace, Trine Tsouderos, and others were portrayed as cannibals sitting down to a Thanksgiving feast of baby. Meanwhile, anti-vaccine luminaries invoke the pharma shill gambit with abandon and try their best to smear journalists who write about how anti-vaccine views are endangering herd immunity, journalists such as Trine Tsouderos, Amy Wallace, Chris Mooney, and Seth Mnookin, to name a few.

Sometimes, however, for whatever reason karma, fate, God, or whatever you want to call it smiles on anti-vaccine activists, dropping a story into their laps that allow them to indulge the worst of their tendencies towards ad hominem attacks and seem superficially credible. So it was about a year ago when an financial fraud investigation was being undertaken in the case of Poul Thorsen, a Danish investigator who had contributed to two large Danish studies, one of which failed to find an association between the MMR and autism in the immediate wake of Andrew Wakefield’s falsified data suggesting such an assocation and one of which failed to find an association between mercury in the thimerosal preservative in vaccines and an increased incidence of autism. At the time longstanding anti-vaccine propagandist Robert F. Kennedy, Jr. tore into Thorsen with abandon before he was even indicted or charged (he was only under investigation at the time) as though, even if he actually did commit fraud, such fraud invalidated the two large studies regarding MMR and autism and thimerosal and autism with which he had been involved. Did it?

To find out, let’s hop into our SBM TARDIS and go back in time about a year, in order to see the genesis of this manufactorversy that AoA is currently flogging. Let’s look at the case of Danish investigator Poul Thorsen as it developed.

Watch Steve Novella on The Dr. Oz Show on Tuesday!

UPDATE 4/27/2011: Here’s the online video of Dr. Novella’s appearance on The Dr. Oz Show:

  1. Controversial Medicine: Alternative Health, Part 1
  2. Controversial Medicine: Alternative Health, Part 2
  3. Controversial Medicine: Alternative Health, Part 3

I can’t believe I’m saying this, but I want you all to tune in to The Dr. Oz Show on Tuesday, April 26. Either that, or DVR it. Why am I asking you to do this? Have I lost my mind? Have I suddenly gone woo? Of course not. The reason is that, an episode I’ve been waiting for since I learned it was in the works last week will air on that date.

That’s right. Our fearless leader Steve Novella will be on The Doctor Oz Show this Tuesday to do battle in the belly of the beast.

Unfortunately, I fear for the results. I know Steve acquitted himself quite well, at least as well or better than any skeptic and booster of SBM could hope to do in such a hostile environment, but get a load of the title of the segment, Controversial Medicine: Why your doctor is afraid of alternative health?

Afraid?

Afraid?

Afraid?

No, no, no, no! A thousand times no!

I do worry a bit how the producers edited Steve’s segment, though. Look at the promo. In it Dr. Oz is doing what I was afraid of, trying to portray himself as the voice of reason and accusing Steve of being “dismissive.” I was afraid Dr. Oz would play the “don’t be close-minded” or “you’re too dismissive” card, and he appears to have done it. Then get a load of the advertised segment that follows, showing Dr. Oz dictating what’s true and not in medicine, as in “Dr. Oz approved.”

Truly, the man has no shame.

I’ll have to wait until Tuesday to see what the final results are. Whatever happens, we at SBM are all incredibly proud of Steve for going into the proverbial lions’ den. As managing editor, I’m also enormously proud of our stable of bloggers; after all, it is a collective effort that got us noticed by the producers of The Dr. Oz Show. Also, now that Dr. Oz and his producers have noticed us, however the segment turns out we promise to keep holding Dr. Oz’s feet to the fire when he starts promoting nonsense like faith healers, psychic mediums, dubious diabetes treatments, and über-quacks like Joe Mercola. This should be facilitated by our new partnership with the James Randi Educational Foundation that was announced earlier this week.

You can also rest assured that Steve will blog about his experience after the episode airs, and I hope our readers will dive into the discussion forums after the show.

CAM In Medical Schools

A recent US News and World Report article on the incorporation of complementary and alternative medicine (CAM) into US medical schools credulously repeats the pro-CAM marketing hype. There is no evidence that the author, Meryl Davids Landau, spoke to a single critic of CAM, or is even aware that such criticism exists. The result looks more like marketing copy than serious journalism.

She begins:

Now that nearly 40 percent of American adults swear by some form of complementary and alternative medicine, or CAM—from nutrition and mental relaxation to acupuncture, magnet therapy, and foreign healing systems like traditional Chinese medicine and Indian ayurveda—a growing number of medical schools, too, are supplementing medication with meditation.

There is much to deconstruct just in this first paragraph. The entire article in an argument from popularity. This is a game the pro-CAM community has been playing for years. People are using CAM because it’s popular; medical schools should teach it because people are using it; the government should research it because of all the interest in it; and CAM should be popular because it’s being researched and taught in medical schools. CAM is like Paris Hilton – famous for being famous.

The World Has Moved On

I do a lot of driving as part of my job.  I am the sole Infectious Disease doctor at three hospitals and I can spend an hour or two a day in the car, depending on traffic.  What prevents me from going crazy sitting in traffic is listening to podcasts and audible books.    I especially like reading (and yes, audio books is reading, pedant) multivolume epics.   Currently I am reading Steven King’s Dark Tower series, which occurs in a universe “where the world has moved on.”  In Mid-world there was once a world with science and beauty and art, but something changed, what I do not know yet (I am only on the third volume; no spoilers in the comments), and the world moved on, leaving behind some artifacts of science and technology, but it appears to be an increasingly primitive world.  Being fantasy, there is, unlike the world I live in, magic as well.

I like that phrase: “the world has moved on.” (more…)

Anti-vaccine propaganda from Sharyl Attkisson of CBS News

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.

The Hazards of “CAM”-Pandering

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.

Ann Coulter says: Radiation is good for you!

Here at Science-Based Medicine, we try to be relatively apolitical. We might not always succeed, but in general our main concern is not so much with right-wing or left-wing politics, but rather with how prevailing government policies and regulation impact the delivery of medical care, in particular whether they tend to prevent, do nothing about, or promote the proliferation of non-science-based medical care. Consequently, when Kimball or I call for the disbanding of the National Center for Complementary and Alternative Medicine (NCCAM), it does not matter one whit to us who is President or which party controls Congress. All that matters is that we see NCCAM as a government entity that, through credulously studying many “alternative medicine” modalities, ends up inadvertently promoting them and providing them with the imprimatur of government approval. The same concept applies to state medical licensing boards licensing pseudoscientific modalities, such as naturopathy, acupuncture, and homeopathy. By regulating these “disciplines,” states also provide them with an unmerited mantle of respectability through their imprimatur of regulating them as professions, just like medicine and nursing.

As far as political views, although all of us have them and they occasionally even come to the fore in disagreements (remember when Wally Sampson occasionally clashed with others with differing political viewpoints?), we generally subsume them for purposes of the SBM blog experience into our advocacy for basing medicine on the best science available. Sometimes, however, when a pundit or politician makes claims that are either contrary to or distort science for ideological or political advantage, I feel the need to discuss those claims, sometimes even sarcastically. Such was the case last week, when Ann Coulter wrote a blisteringly ignorant column, entitled A Glowing Report on Radiation. She wrote this article in the wake of the fears arising in Japan and around the world of nuclear catastrophe due to the damage to the Fukushima nuclear power plant caused by the earthquake and tsunami that hit northern Japan on March 11. Coulter was subsequently interviewed by Fox News pundit Bill O’Reilly on The O’Reilly Factor on Thursday evening:

Yes, according to Coulter, radiation is good for you, just like toxic sludge! Even more amazing, in this video Bill O’Reilly actually comes across as the voice of reason, at least in comparison to Ann Coulter. He’s very skeptical of Coulter’s claims and even challenges her by saying, “So by your account we should all be heading towards the nuclear reactor.”

So, fellow SBM aficionados, is Coulter right? Are all those scientists warning about the dangers of even low-level radiation all wrong? Should we start hanging out in radioactive mine shafts, as Coulter mentions in her column (seriously) in order to boost our health and decrease our risk of cancer?

Not so fast, there, Ann. Here’s a hint: If Bill O’Reilly can lecture you on science and look more reasonable than you, you’re off the rails.

Dr. Oz and John Edward: Just when I thought Dr. Oz couldn’t go any lower, he proves me wrong

I’ve really come to detest Dr. Mehmet Oz.

You remember Dr. Mehmet Oz, don’t you? How can you escape him? He is, after all, Oprah Winfrey’s protege, and of late he’s really been living up (or down) to the example set by his television mentor, who of late apparently thinks nothing of promoting faith healing quack John of God on her show. Following in the footsteps of his much more famous and well-known mentor, this season on his television show, The Dr. Oz Show, Dr. Oz has in some ways imitated Oprah and in some ways gone her one better (one worse, really) in promoting the Oprah-fication of medicine. And this season has been a particularly bad one for science-based medicine on The Dr. Oz Show. Apparently Dr. Oz felt that he had to surpass what he did last season, which included inviting a man whom I consider to be one of the foremost sellers of quackery on the Internet, Dr. Joseph Mercola. Prior to that, Dr. Oz had done an episode touting the glories of that form of faith healing known as reiki. In between, he made appearances at various panels of woo-friendly physicians trying to coopt President Obama’s health insurance reform initiative to cover more “holistic” care (i.e., “integrative medicine”).

In the next season, in particular over the last couple of months, Dr. Oz showed me just how wrong I had been when I had previously been saying that Dr. Oz seemed to be mostly science-based but with a soft spot for certain kinds of pseudoscience. This season, Dr. Oz has thrown down the gauntlet to science-based medicine (SBM) and, as I like to put it, crossed the Woo-bicon. First, he not only invited Joe Mercola back on his show, but he did it defiantly, defending Mercola against what I consider to be much-deserved charges of being a seller of quackery and lauding him as a “pioneer of holistic treatments.” A couple of weeks later, Dr. Oz pulled the classic “bait and switch” of alternative medicine, featuring a yoga instructor on his show who also advocated all sorts of Ayruvedic quackery. Then, a mere few days later Dr. Oz, apparently not satisfied at his transformation from nominally science-based to being based solely on whatever would bring him higher ratings, completed his journey to the Dark Side of quackery by credulously featuring a faith healer on his show and hosting what has to be the lamest faith healing that I’ve ever seen in my entire life. After that, I didn’t think Dr. Oz could go much lower, although he tried, two examples of which were his anti-vaccine-sympathetic episode on autism in which he featured Dr. Robert Sears and his utterly reversing a previous scientifically correct stance of his and promoting a dubious and potentially dangerous diet.

Ethics in human experimentation in science-based medicine

Science-based medicine depends upon human experimentation. Scientists can do the most fantastic translational research in the world, starting with elegant hypotheses, tested through in vitro and biochemical experiments, after which they are tested in animals. They can understand disease mechanisms to the individual amino acid level in a protein or nucleotide in a DNA molecule. However, without human testing, they will never know if the end results of all that elegant science will actually do what it is intended to do and to make real human patients better. They will never know if the fruits of all that labor will actually cure disease. However, it is in human experimentation where the ethics of science most tend to clash with the mechanisms of science. We refer to “science-based medicine” (SBM) as “based” in science, but not science, largely because medicine can never be pure science. Science has resulted in amazing medical advances over the last century, but if there is one thing that we have learned it’s that, because clinical trials involve living, breathing, fellow human beings, what is the most scientifically rigorous trial design might not be the most ethical.

About a week ago, the AP reported that experiments and clinical trials that resemble the infamous Tuskegee syphilis study and the less well known, but recently revealed Guatemala syphilis experiment were far more common than we might like to admit. As I sat through talks about clinical trial results at the Society of Surgical Oncology meeting in San Antonio over the weekend, the revelations of the last week reminded me that the intersection between science and ethics in medicine can frequently be a very tough question indeed. In fact, in many of the discussions, questions of what could or could not be done based on ethics were frequently mentioned, such as whether it is ethically acceptable or possible to do certain followup trials to famous breast cancer clinical trials. Unfortunately, it was not so long ago that such questions were answered in ways that bring shame on the medical profession.
