I know this one’s been floating around the blogosphere for a while, but it finally made its way to me at a time when I needed something lighthearted and amusing (warning: some profanity and at least one use of the “F” word):
“Well, science doesn’t know everything.” Well, science knows it doesn’t know anything, otherwise it would stop … But just because science doesn’t know everything doesn’t mean you can fill in the gaps with whatever fairytale most appeals to you.”
…”nutritionist” isn’t a protected term. Anyone can call themselves a nutritionist. “Dietitician” is the legally protected term. “Dietician” is like dentist, and “nutritionist” is like tootheologist.”
“I’m sorry if you’re into homeopathy. It’s water. How often does it need to be said? It’s just water. You’re healing yourself. Why don’t you give yourself the credit?
I just wish more comics did routines like this. Sometimes humor can get the message through where analysis can’t.
When I started this series on Functional Medicine, David Gorski suggested looking at Mark Hyman’s web page, which I had seen months before, but thought did not reveal much. That was a wrong. It shows a lot, and I suggest bloggers et al review it.
So I decided on a fourth “functional medicine” (FM) installment, in search of what it FM really is. On the Mark Hyman web page and in his Public TV monolog fund-raiser, Hyman follows a seven point outline of what he believes Fuctional Medicine (“FM”) is. If one follows the 7 “keys” as he writes, optimum health, “ultra-wellness” happens. Here are the points:
- Environmental inputs
- Gut & digestive health
- Energy/Mitochondria/Oxidative Stress
- Mind body
Fall is around the corner, and with it comes the influenza season. Each year an average of 200,000 people in the US are hospitalized with influenza, and 36,000 die.1,2 With the addition of the novel H1N1 strain (swine flu), this season promises to be more interesting, and even less predictable, than most. There can be no doubt, however, that this one set of viruses will exact a heavy toll for thousands of families this season.
Too often in medicine we find ourselves confronted with problems we cannot fix. Some traumas are too severe, some infections have too much of a head start. Some diseases are poorly understood, while others have no known treatment. One of the darker adages of medicine still holds true: In spite of all our advances, the world mortality rate seems to be holding quite steady at 100%.
Thankfully, influenza is not a disease against which we are helpless. We have ways to limit its spread, and medicines with a modest effect in assuaging symptoms and shortening the length of illness. Most importantly, we have vaccines that can safely prevent the disease altogether.
There are myriad misconceptions and fears surrounding the influenza and its vaccines, most are not new and have been addressed elsewhere, including the concern that the influenza vaccines cause the flu (they don’t), that the thimerosal they contain causes autism (it doesn’t), and that it can trigger Guillan Barre Syndrome (it can3, at a rate of 1/1,000,000, similar to the background rate of Guillan Barre in the population4). The confusion has been compounded by the emergence of the novel H1N1 pandemic. With so much at stake, it is exceedingly important to have clear, accurate information available to physicians and the public alike. (more…)

Readers acquainted with popular culture know that such inane, annoying phrases are typical of American women’s magazines. Thus it may be surprising to learn that only three entries were quoted from sources clearly recognizable as such: numbers 3 and 6 from Cosmopolitan, and number 11 from Glamour. The rest were found in WebMD: the Magazine:
The magazine appears to have been introduced in 2005. According to its masthead page,
WebMD’s mission is to provide objective, trustworthy, and timely health information. Our website and magazine provide credible content, tools, and in-depth reference material about health subjects that matter to you. We are committed to providing information on a wide variety of health topics, all of which are reviewed by our board-certified physicians.
Every physician I know receives a “COMPLIMENTARY WAITING ROOM COPY” each month; the 3 or 4 waiting rooms that I’ve perused have been amply stocked. I suspect that most office managers are happy to be provided with free reading material that seems appropriate for patients, and that most physicians haven’t given the magazine more than a passing glance. The problem is that the magazine, like the consumer website of the same name, offers a mixture of accurate-if-mundane information, misleading health claims, exaggerated nutritional advice, unwarranted fear-mongering, and pseudoscientific nonsense. I’ll limit examples and comments to the final four categories. (more…)
So far I have explained why most research (if not carefully designed) will lead to a false positive result. This inherent bias is responsible for many of the illusionary treatment benefits that we hear about so commonly through the media (whether they’re reporting about CAM or Western medicine), because it is their job to relay information in an entertaining way more so than an accurate manner (i.e. good science makes bad television).Then I explained a three step process for determining the trustworthiness of health news and research. We can remember these steps with a simple mnemonic: C-P-R.
The C stands for credibility– in other words, “consider the source” – is the research published in a top tier medical journal with a scientifically rigorous review process?
The P stands for plausibility– is the proposed finding consistent with known principles of physics, chemistry, and physiology or would accepting the result require us to suspend belief in everything we’ve learned about science to date?
And finally we arrive at R – reproducibility. If the research study were repeated, would similar results be obtained? (more…)
We frequently receive requests from readers, our colleagues in medicine or fellow science bloggers for the best reference site that has all the information they need on a specific topic. There are many excellent resources on the net, but nothing I know of that quite puts it all together in that way – one-stop shopping for up-to-date information on the topics we are most concerned with.
So we decided to create just such a resource.
You will now see at the top of this page a new link for SBM Topic-Based Reference which leads to our new section by that name. There you will see the list of topics we are currently working on, and once they are complete more will be added. As of today only one topic is reasonably complete, Vaccines and Autism.
The format (which is subject to change as we build and use the resource) is as follows: We start with a brief topic overview. This is not meant to be a thorough discussion of the topic, but a quick summary to get people started. This is followed by an index of all SBM posts on that topic and then links to outside resources that we recommend.
I recently wrote an article for a community newspaper attempting to explain to scientifically naive readers why testimonial “evidence” is unreliable; unfortunately, they decided not to print it. I considered using it here, but I thought it was too elementary for this audience. I have changed my mind and I am offering it below (with apologies to the majority of our readers), because it seems a few of our readers still don’t “get” why we have to use rigorous science to evaluate claims. People can be fooled, folks. All people. That includes me and it includes you. Richard Feynman said
The first principle is that you must not fool yourself–and you are the easiest person to fool.
Science is the only way to correct for our errors of perception and of attribution. It is the only way to make sure we are not fooling ourselves. Either Science-Based Medicine has not done a good job of explaining these vital facts, or some of our readers are unable or unwilling to understand our explanations.
Our commenters still frequently offer testimonials about how some CAM method “really worked for me.” They fail to understand that they have no basis for claiming that it “worked.” All they can really claim is that they observed an improvement following the treatment. That could indicate a real effect or it could indicate an inaccurate observation or it could indicate a post hoc ergo propter hoc error, a false assumption that temporal correlation meant causation. Such observations are only a starting point: we need to do science to find out what the observations mean. (more…)
I don’t recall if I’ve mentioned it on SBM before, but I went to the University of Michigan. In fact, I didn’t go there just for undergraduate studies or medical school, but rather for both, graduating with a B.S. in Chemistry with Honors in 1984 and from medical school in 1988. In my eight years in Ann Arbor, I came to love the place, and I still have an affinity for it, even though it’s been over 20 years since I last walked about the campus as a student, although I have been back from time to time for various functions, most recently to see Brian Deer speak last winter. True, I’m not fanatical about it, as some of my contemporaries and friends who attened U. of M. with me back in the 1980s (and, sadly, the string of losses to Ohio State and the definitively mediocre last season Michigan had last year make it very hard to be a Michigan football fan these days). However, I do have considerable affection for the place. It molded me, trained me in science, taught me medicine, and provided me the basis for everything I do professionally today.
First some background. I was first directed to the Marshall protocol by a reader who wondered about the information the found on the web. So I went to the web and looked at the available information, much as any patient would, and discussed what I found there.
I have subsequently been lead to believe that none of the information on the website http://www.marshallprotocol.com can be considered up to date or accurate. As as result of, I have told that my post is chockablock with errors, although, outside of writing doxycycline where I should have put minocycline, I am left in the dark as to exactly what my errors are. I am told that it is my responsibility to locate the errors in the last post, yet I can find none when compared to the website.
However, to remedy the deficiency of having reviewed inaccurate and out of date material, I have been sent 6 articles that I am informed represent the state of the art in understanding the science behind the Marshall protocol. Ah, the peer reviewed medical literature. An opportunity to carefully read and critique new ideas. It is one of the reasons people publish: to see if their ideas can withstand the scrutiny of others.
Several of these papers concern Vitamin D, the Vitamin D receptor, and olmesartan which I will review, perhaps, another time. I don’t find them a compelling read, but it not an area about which I have more than a standard medical knowledge. The other papers concern the role of infection in autoimmune diseases, which I will discuss here. It is easier as an infectious disease doctor to read this literature as I am, as least as far as the American Board on Internal Medicine is concerned, a specialist in the field. Alternatively, I am a closed minded tool of the medical industrial complex who only seeks to push his own twisted, narrow agenda at the expense of suffering patients (1). We can’t all be perfect.
In part 2 of the Science-Based Medicine 101 series we take a look at the second pillar of good science: plausibility. This blog post was written for a lay audience so more advanced readers will need to indulge me here…
I really enjoy sci-fi action movies. I love the convincing special effects and the fact that heroes can accomplish the physically impossible without skipping a beat. Implausible events unfurl with convincing reality, and you never know what might happen with the plot.
I also enjoy the TV show, America’s Funniest Home Videos, for different reasons. The mundane nature of actual reality, and the often predictable, but hilarious mistakes made by those I relate to result in some pretty hearty laughs.
But there is a big difference between these two forms of entertainment: science-fiction requires the suspension of belief in plausibility, while home videos are based on plausible outcomes. When it comes to medical research, though, plausibility can mean the difference between science fiction and reality.
