Dr Oz and Alternative Medicine site

Oz is the man behind the curtain (as in the movie) and has become a joke in the scientific field.  Like Glenn Beck, he is an entertainer!   And I believe his license should be taken away.  He is putting out information that people want to belive because it comes from a DOCTOR.  What they don't take into account is that this guy is on the network payroll, not practicing medicine.  Such a shame that people are so easily misled just becuse he has a few letters after his name.

A Skeptic In Oz

UPDATE 4/27/2011: Here's the online video of Dr. Novella's appearance on The Dr. Oz Show: Controversial Medicine: Alternative Health, Part 1 Controversial Medicine: Alternative Health, Part 2 Controversial Medicine: Alternative Health, Part 3

I must say I was a bit shocked two weeks ago when I was contacted by a producer for The Dr. Oz Show inviting me on to discuss alternative medicine. We have been quite critical of Dr. Mehmet Oz over his promotion of dubious medical treatments and practitioners, and I wondered if they were aware of the extent of our criticism (they were, it turns out).

Despite the many cautions I received from friends and colleagues (along with support as well) - I am always willing to engage those with whom I disagree. I knew it was a risk going into a forum completely controlled by someone who does not appear to look kindly upon my point of view, but a risk worth taking. I could only hope I was given the opportunity to make my case (and that it would survive the editing process).

The Process

Of course, everyone was extremely friendly throughout the entire process, including Dr. Oz himself (of that I never had any doubt). The taping itself went reasonably well. I was given what seemed a good opportunity to make my points. However, Dr. Oz did reserve for himself the privilege of getting in the last word-including a rather long finale, to which I had no opportunity to respond. Fine-it's his show, and I knew what I was getting into. It would have been classy for him to give an adversarial guest the last word, or at least an opportunity to respond, but I can't say I expected it.

In the end I decided that I had survived the taping of the show and did fairly well. After watching the final version that aired I feel that the editing was fair. They allowed me to make my major points, and did not change anything significant about the discussion. Again, the real problem was that Dr. Oz controlled the framing of the discussion and made many fallacious points at the end that I was given no opportunity to respond to.

What are you afraid of?

But enough about the process-let's get to the meat of our discussion. I knew that no matter what happened on the show, I would have the opportunity to give my unfettered analysis here at SBM-so here it is. I knew going in that the biggest challenge would be the way in which Dr. Oz framed the debate, and right at the beginning this was evident. The name of the segment was "Why your doctor is afraid of alternative health."

David Gorski has already pointed out the obvious - we are not afraid of anything. Dr. Oz tried to make it seem as though doctors are afraid of the controversy, because it will result in professional criticism. He accused me (he spent a lot of time arguing against straw men of his own creation) of not wanting to discuss so-called alternative medicine, either professionally or with my patients.

Here is where being a skeptic who deals with a wide range of issues comes in handy. We get the same exact nonsense from believers in alien visitation, psychic phenomena, ghosts, or whatever - they naively and self-servingly assume that anyone who disagrees with them must be afraid of something. The reality is we are just interested in the truth. With respect to medicine, we want to do our professional due diligence to make sure that the treatments we recommend to our patients are based upon the best scientific evidence available. We take the dictum "first do no harm" very seriously - and the only way to be sure that you are not causing harm is to rely on objective, high-quality evidence. It is always about the scientific evidence. But proponents of modalities that are not backed by evidence, like Dr. Oz, desperately want to make the debate about something else. So they invent issues that don't exist, such as being afraid.

It is also patently untrue that my colleagues and I don't want to discuss alternative medicine. Quite the contrary: if anything, we are accused of discussing it too much. We spend a great deal of time acquiring expertise in a long list of sectarian and controversial treatments, so that we can discuss them with authority. I talk to my patients all the time about treatments considered "alternative" (if you haven't figured it out yet, this is a term we do not like because it encourages a false-dichotomy and is a distraction from the key question - whether it is safe and effective). They ask me questions, and I give them evidence-based answers, without judgment or fear.

I find that my patients greatly appreciate that I have taken the time to understand the research on such topics and can give them accurate, no-nonsense information they can use. This is essential for informed consent, which is part of medical ethics.

In short, we are not afraid of anything. We want there to be open debate and discussion. We want to shed as much light as possible on controversial and "alternative" methods, because we feel the public and individual patients will benefit from having all the information. SBM is largely dedicated to providing that information. Our criticism of Dr. Oz and others who promote such modalities is that they give the public partial or distorted information - often grossly so.

A recent example is an episode a few weeks ago in which Dr. Oz uncritically promoted homeopathy. He told his audience that the evidence shows that homeopathy works, even if the mechanism may be mysterious. He stated this as a non-controversial fact, which was very misleading. Every objective review of the clinical evidence demonstrates that homeopathic products do not work for any indication.

A Stent and a Statin

Another example of the dissemination of biased or partial information comes from the other guest appearing on that segment with me, Dr. Mimi Guarneri. Her schtick is that she is an interventional cardiologist who became disillusioned with mainstream medicine and was drawn to the focus on preventive measures in alternative medicine. This, of course, is complete fiction - nothing but marketing hype by promoters of dubious treatments.

On the show she summarized the mainstream approach to heart disease by saying that, as a conventional doctor, the only tools she had in front of her were a "stent and a statin." This is nice alliteration, and I'm sure it plays well with her target demographic, but it is highly deceptive. Calling such a statement "unfair" is being charitable.

I pointed out during taping that science-based medicine has identified and actively promotes many modalities for preventing heart attacks, in addition to stenting blockages and using statin medication to lower blood cholesterol. These include diet for weight and cholesterol control, exercise, controlling diabetes, controlling high blood pressure, and using ‘blood thinners' like aspirin.

I could have added that scientific studies are also looking into the role of chronic anti-inflammatory treatments (perhaps it is the anti-inflammatory effects and not the anti-platelet effects of aspirin that are most effective in preventing heart attacks). There are frequently published studies examining every aspect of diet to see which factors are most helpful. A diet with excess simple sugars may also be detrimental, although its exact contribution remains controversial. And just about every vitamin has been looked at for its preventive effects (which turn out to be modest, and high doses of vitamin E may actually increase heart disease risk). The benefits of stress reduction have been clearly established by scientific studies, and is also part of standard recommendations.

Modern medicine has examined every nook and cranny of heart disease prevention, and continues to do so as new ideas come to light. Where are the great innovations to cardiac disease prevention brought by so-called alternative medicine? They appear to be non-existent - except for dubious claims made for superstition-based treatments that were rejected long ago by science.

This is the kind of ideologically-driven misinformation that has earned Dr. Oz our criticism.

Heads I Win, Tails I Win - Now Stop Being so Dismissive

If there were any doubt where Dr. Oz is ideologically, he removed it during this episode. He clearly staked out the anti-scientific ground that most defenders of alternative medicine use to dismiss criticism of their claims. Make no mistake - at its heart the disagreement between defenders of science-based medicine and promoters of alternative medicine is an ideological struggle over the role of science in medicine. We have made our position at SBM clear (which also reflects the consensus opinion in the medical profession) - science is the best method for determining which medical interventions are safe and effective and which are not.

Promoters of alternative medicine only pay inconsistent lip-service to science, but the core of their philosophy is that science is optional. They rely upon the fact that to many non-scientists, the word "science" is sufficiently arcane that they can use the term to generate confusion.

What we mean by "science", however, is simply rigorous methods of observation. Good science looks at all the evidence (rather than cherry picking only favorable evidence), controls for variables so we can identify what is actually working, uses blinded observations so as to minimize the effects of bias, and uses internally consistent logic.

So when promoters of alternative medicine claim that science is not always the best method to test their claims, which part are they willing to reject? Perhaps they want to dismiss inconvenient evidence, or use logical fallacies, or sloppy research methods, or just make things up as they go along.

Dr. Oz played this game during the show as well. He claimed that for many "alternative" modalities there is scientific evidence to back them up. But he focused on herbal therapy to make his point. This a bit of the bait and switch (and why the false category of "alternative medicine" is counterproductive). Herbal remedies are not really alternative - they have been part of scientific medicine for decades, if not centuries. There is even a research specialty focusing on pharmacognosy - or using natural sources for drug development. Herbs are drugs, and they can be studied as drugs. My problem is with the regulation and marketing of specific herbal products, because they often make claims that are not backed by evidence.

But there is no a priori reason to think that any particular herbal drug will or will not be safe and effective. It just needs to be properly studied.

For modalities where there is some evidence of efficacy, Dr. Oz is all in favor of science. But when the discussion turned to acupuncture, where the evidence is largely negative, Dr. Oz suddenly characterized reliance on "Western" science (another false dichotomy) as arrogant and dismissive. Western science, he argued, cannot wrap its collective head around something as Eastern and mysterious as acupuncture (although he recoiled when I characterized this approach as mysticism - again, he seems to want to have it both ways).

This is a clearly anti-scientific attitude. When studies are positive, science is great. When studies are negative, Western science cannot fathom alternative medicine and relying on research is "arrogant." Heads I win, tails I win.

Never mind that much of the acupuncture research is designed in cooperation with, and executed by acupuncturists. They signed off on the research and certainly would have claimed support if the studies turned out positive. In fact, they've even tried to claim, as ‘positive,' studies that were completely negative - another example of deception in the world of alternative medicine.

I wish I'd had the opportunity to ask Dr. Oz exactly what is it about "Western" science that makes it incapable of detecting any real physiological effect from acupuncture or a similar method. This is the same intellectual failing as claiming that Bigfoot can turn invisible at will, to explain why there are no good pictures of him. Or that psychic powers do not function in the presence of skeptics.

This is a logical fallacy (special pleading) with which we are very familiar. Ironically, it is a very dismissive attitude - the casual dismissal of scientific evidence simply because it contradicts a pet belief. The scientific approach, of course, is to look fairly at all the evidence - a process that Dr. Oz unfairly characterized as "dismissive."

Conclusion

In the end I am glad for the opportunity to expose science-based medicine to a wider audience. Despite the accusation that we are "afraid" of alternative medicine, we are anxious to address it head on. Honest and open intellectual discourse is the way to work out such differences of opinion and approach, and we are confident in our ability to defend science-based medicine.

I wonder if Dr. Oz is as confident. I was happy to go into his forum, where he and his producers controlled the conversation. In return I invite Dr. Oz to continue our discussion, either in written form here at SBM or on my podcast, the Skeptics' Guide to the Universe. We have interviewed those on the "other side" before, and have given them essentially an unedited forum to express their opinions and answer questions. I passed this offer to Dr. Oz through his producer (but I don't know if he actually received the invite, and I was not given the chance to make it directly during the taping of the show).

So I repeat the offer here in public. There is a lot to hash out about so-called alternative medicine and the role of science in medicine. Let's continue the discussion, on SBM or the SGU - you have an open offer, Dr. Oz, and you obviously know how to contact me.

Thanks, thatgirl.

I was unaware that Dr. Oz was so progressive. I will dig deeper!

My sister has been pestering me to watch certain shows. I certainly didn't realize some of the things he points out-- that you should get a thyroid shield when you get a mammogram because of the radiation. really good advice.

Black-Cat, i admire your research. great job.

i read an article about Dr. O a few years ago - maybe in the NYT magazine. the reporter describes Oz as having "the most joyless approach" to eating. i found that interesting. i've never cared much for him - he seems to talk at people, instead of with them. lots of ego, imo.

Thanks for the reminder about Dr Oz. I will DVR him.

I get that Doctors Show here but that ob-gyn on the panel is so scary-stupid I only watched it a few times. There was a whole support group attached to the show website on the things she gets wrong. Even her former patients wrote in saying how awful she was.

Dr Oz is like any other person.  You have to take the info and decide whether or not it bears doing the research yourself.  Not much in medicine is black and white.  Nor are we all alike in our needs.  I respect Dr Oz for presenting some rather simple and effective ways to deal with some of our issues in a preventative manner.

Hi Pip57, I have to respectfully disagree that "Dr Oz is like any other person."  I know what you mean, that we need to evaluate health infomation, no matter where it comes from, but IMHO, Dr. Oz is doing a terrible disservice to his large audience when he endorses some of the BS he's becoming known for.  I view him as just another celebrity entertainer pandering to his bank account rather than out of concern for the health of his viewers.  Progressive? Not. Of course a lot of what he says is common sense and/or reasonable advice, and that helps boost his credibility.  Unfortunately, IMHO, he is in a position of trust and power, and he's abusing that.

The links that Black-Cat has provided above are quite useful for anyone looking for evidence-based health information, rather than star-studded daytime television drama.

I say NO to witch burning and YES to public education at large  

Geeze, never knew my bladder worked this way.....

More than 80% of science based research is done by the pharmaceuticals

http://en.wikipedia.org/wiki/Contract_research_organization

A significant portion of R&D budgets are used for the outsourcing services offered by the CRO industry, approximately $15 billion in 2007.^[8] This figure is expected to grow at 15% over the next seven years and should increase further with the broadening of the spectrum of services outsourced to cover the entire value chain. As outsourced services in developing countries such as China and India move up the value chain to cover phase 1/2 trials, the total contracts value may go up to $20 billion by 2010. Further, certain therapeutic areas within pharmaceutical development are slated for an even greater growth curve, namely the oncology class, expected to see continued growth of upwards of 21% over the next few years^[9] due to the large target market, strong unmet medical need, and overwhelming number of drugs currently in development (667 for cancer vs. 252 for CNS disorders, 206 for cadiovascular disorders, and 186 for infections).^[10][

CROs support the pharmaceutical, biotech and medical device industries as well as foundations, research institutions, and universities, in addition to governmental organizations (such as the NIH, EMEA, etc.).

There you go Pip

Several weeks ago, I saw that "award" that Dr. Oz received  and said to myself, "Wow!  So I wasn't the only one questioning Dr. Oz."

Whenever I want to find out about ANYTHING medical, I turn to Pubmed, which is a database created by the government of ALL medical studies throughout the world.  You can spends days researching clinical trials and studies.  Sadly, many of us don't have the time or the comprehension abilities to do that, so instead we have to receive our medical information from people whom we believe are "informed."  Big mistake.  Take the time and TRY to do your own research.  Often, if I don't understand something, I will contact the lead investigator of a study.  You'd be surprised how often they will respond to your inquiries.

In MHO, watching Dr. Oz is a waste of time.  Instead, use that time to do your own research.  And one other piece of advice....you want to make sure that the studies you are reading are appearing in the "leading" respected journals.

gracie1:  I agree!  The narcissism associated with Oprah, and her Oprahites like Dr. Oz and Dr. Phil, is something to consider.  I think any and all information passed by these types of shows should be used as a stepping stone, only...not the the truth.  Research is essential. 

Well, so far we agree.  I always do my own homework before adopting something for my own use.  But I do find it much more helpful to have an explanation of 'why' something is considered useful and Dr Oz often helps to explain that.  

And trust me, I am no Oprah fan.   

 NYTIMES:

Thyroid Fears Aside, That X-Ray's Worth It

By JANE E. BRODY

It doesn't take much to scare people when it comes to cancer, especially when the cause, unlike smoking, seems beyond one's control.

So I was not surprised by a stream of panicked e-mails I received after a television show in which the popular Dr. Mehmet Oz called thyroid cancer "the fastest-growing cancer in women" and cited the harmful effects of radiation from sources like dental X-rays and mammograms.

Dr. Oz warned that people who have more than five X-rays a year have a fourfold greater risk of developing this cancer, and recommended the use of a lead thyroid shield when getting dental X-rays or mammograms. One of his guests on the program, Dr. Carolyn Runowicz, a gynecological cancer specialist, said she would not get dental X-rays if the only reason was to check her teeth.

Thyroid cancer is much on people's minds, particularly because of the nuclear reactor accident in Japan. After all, it has only two known causes: a rare genetic condition and exposure to large doses of radiation, especially during childhood.

The effects of radiation are cumulative, so in theory frequent exposure to even low doses could add up to a cancer risk. So what are the facts about radiation and the thyroid, and how concerned should you be about an annual mammogram or dental X-rays every few years?

Here are a few things to remember:

¶Thyroid cancer is relatively rare, accounting for about 3 percent of all cancers in women, 1 percent in men and 1.4 percent in children.

¶Diagnoses of thyroid cancer have increased sharply in recent decades. Between 1980 and 2007, the incidence rose to 17 per 100,000 from 6 per 100,000 each year, and to 5.8 per 100,000 from 2.5 per 100,000 men each year. The number of diagnoses in women nearly doubled from 2000 to 2008.

¶Yet the death rate from this disease has not increased, and more than 97 percent of patients survive.

Dr. Otis W. Brawley, chief medical officer of the American Cancer Society, said the stable death rate despite a rising incidence strongly suggests that most of the thyroid cancers now being diagnosed would never have become a health threat.

"Our technology has gotten so good that we are finding cancers today that even 15 years ago would not have been diagnosed," Dr. Brawley said in an interview. "We're finding and treating cancers that would never have killed anyone."

Advances in Diagnostics

In a study describing a 140 percent increase in thyroid cancers diagnoses from 1973 to 2002, published in The Journal of the American Medical Association in 2006, researchers at the Veterans Affairs medical center in White River Junction, Vt., also concluded that the rise was the result of "increased diagnostic scrutiny."

They noted that if there were a true increase in thyroid cancer, the rise would be reflected in patients at every stage of the disease. But in their study, 87 percent of the increase was attributable to diagnoses of small papillary thyroid cancers, many of which would never have caused any problem.

The fact that thyroid cancer increased in all age groups from 2000 to 2008, Dr. Brawley said, "is more consistent with the introduction of new diagnostic technology than with any cause like mammography." If mammography were a factor in the rise of thyroid cancer, he added, you'd expect to see a greater rise in women older than 50 than in women ages 20 to 40.

Dr. Leonard Wartofsky, a thyroid cancer specialist at Washington Hospital Center in the District of Columbia, said in an interview, "The doses associated with mammography have been well studied and well calibrated. As long as it is done with modern equipment, women should not be concerned. That degree of radiation is not consequential."

The higher rates of thyroid cancer found in women could also reflect the fact that many are checked annually by gynecologists, who routinely examine the thyroid region for possible enlargement, Dr. Brawley suggested.

With regard to dental X-rays, he noted that the amount of radiation exposure associated with them has decreased considerably in the last 20 years, which is inconsistent with a rise in thyroid cancer diagnoses.

Radiation Risks

To be sure, exposure to high doses of radiation, especially in childhood, raises the risk of cancer, and thyroid cancer in particular. Well before this risk was recognized, radiation was widely used to treat benign conditions like enlarged tonsils and adenoids, acne and ringworm of the scalp.

Thyroid cancers afflicted many who were exposed as children, or even prenatally, to large amounts of radiation when Americans dropped atomic bombs in Japan in 1945 and when the Chernobyl accident occurred in 1986.

While very large doses of radiation destroy the thyroid, moderately high doses - like those that are used to treat Hodgkin's disease or tumors of the head and neck - can cause genetic mutations that develop into cancer.

But what of lower doses? Studies of the relationship between frequent dental X-rays and thyroid cancer have been conflicting, and in some the methodology has been suspect. (Some reports, including a frightening one from Kuwait, relied on people's ability to remember the X-rays they received.)

But the best study of diagnostic X-ray exams, conducted in Sweden, where precise medical records are kept, found no connection to thyroid cancer.

Other factors linked to an increased risk of thyroid cancer include consumption of nitrates in public water supplies (from fertilizer runoff) and certain vegetables, andgoiter caused by insufficient iodine in the diet.

Playing It Safe

There's no harm in asking a mammographer to use a lead thyroid collar, and a lead apron should cover the front of the neck during dental X-rays. Still, some internal radiation scatter will occur, Dr. Brawley said.

Dr. Wartofsky suggested that women worried about the radiation from a mammogram could have an M.R.I. or ultrasound exam instead. But check first on insurance coverage for these alternatives.

For dental checkups, find a dentist who uses digital X-rays, which deliver much less radiation. "We've said for years that the amount of radiation from dental X-rays is not enough to cause cancer," Dr. Wartofsky said.

And don't let irrational fear get the better of you: It is simply not possible to detect all dental decay without X-rays, and missing hidden decay could result in the need for a root canal or extraction of the tooth.

Re thyroid and xrays...Dr Oz said all of that in his programme.
