It is a triumph of marketing over evidence that millions take supplements every day. There is no question we need vitamins in our diet to live. But do we need vitamin supplements? It’s not so clear. There is evidence that our diets, even in developed countries, can be deficient in some micronutrients. But there’s also a lack of evidence to demonstrate that routine supplementation is beneficial. And there’s no convincing evidence that supplementing vitamins in the absence of deficiency is beneficial. Studies of supplements suggest that most vitamins are useless at best and harmful at worst. Yet the sales of vitamins seem completely immune to negative publicity. One negative clinical trial can kill a drug, but vitamins retain an aura of wellness, even as the evidence accumulates that they may not offer any meaningful health benefits. So why do so many buy supplements? As I’ve said before, vitamins are magic. Or more accurately, we believe this to be the case.
There can be many reasons for taking vitamins but one of the most popular I hear is “insurance” which is effectively primary prevention – taking a supplement in the absence of a confirmed deficiency or medical need with the belief we’re better off for taking it. A survey backs this up – 48% reported “to improve overall health” as the primary reason for taking vitamins. Yes, there is some vitamin and supplement use that is appropriate and science-based: Vitamin D deficiencies can occur, particularly in northern climates. Folic acid supplements during pregnancy can reduce the risk of neural tube defects. Vitamin B12 supplementation is often justified in the elderly. But what about in the absence of any clear medical need? (more…)
I have a confession. I have been interested in issues skeptical since high school when I came across a copy of the Zetetic at Powells. In the pre-digital era I had a complete library of Zetetic-Skeptical Inquirers (SI) that a decade ago was tossed in the recycle bin along with a similar collection of MacWorlds. I have been interested in skepticism a long time and, here is my confession, I no longer find much of the subject matter covered by SI all that interesting. Even big ticket topics like the existence of God are uninteresting. It is not that the topics are not important, they are, and each generation has to relearn why Bigfoot or haunted houses or UFO’s are nonsense. But for me it is a large serving of been-there, done-that.
So while I subscribe to SI, it is more from a sense of obligation to support institutions I think are important than from an expectation that I will be either educated by the content or entertained by the style of the writers. I usually skim the magazine while accomplishing tasks that do not require my full attention probably because SI is the only magazine I still receive in dead tree format, the rest of my life being digital.
So I ran across “Taking our medicine: What hope for skepticism in healthcare?” by Kenneth W. Krause and after skimming it I was irritated. So I read it again and I was more irritated, which is often a good sign. But I could not quite put a finger on what it was. So I read it again and then went for a walk and thought about it.
All the facts were fine. I had no issue with the content of the article. It was the adjectives that irritated me. And the essay was, from my perspective, incomplete. It was like reading a relationship/birth control article by the Pope. Sure, he knows the facts of the situation, but not being an active participant in the process and with an agenda to promote, vital information will be missing or distorted. (more…)
Never let it be said that I can’t match Mark Crislip in shameless self-promotion. The world might indeed need more Mark Crislip™, but I like to think that it needs a bit more David Gorski, too. So, in that spirit, here are the videos, recently released by the James Randi Educational Foundation, of Bob Blaskiewicz, myself, and some key SBM players that you’ve come to know and love. The first video is my talk at The Amazing Meeting in July about Stanislaw Burzynski, MD, PhD. It’s entitled Why We Fight (Part I): Stanislaw Burzynski Versus Science-Based Medicine. The second video is Bob Blaskiewicz, of Skeptical Humanities and The Other Burzynski Patient Group, It’s entitled, appropriately enough, Why We Fight (Part II): It’s All About the Patients. The third video is of the panel that followed to discuss Medical Cranks and Quacks. Enjoy!
Oh, and consider it a bit of a taste of what’s to come tomorrow…and don’t forget to pay attention to Bob Blaskiewicz’s plea at the end of his talk to contact him if you’re interested in becoming active. At TAM, he had a sign-up sheet that he discussed at around 21:06 in the video. Online, just mosey on over to The Other Burzynski Patient Group and contact Bob Blaskiewicz. We will very likely be asking you to help very soon.
Teething is one of the most common sources of parental concern in the world of pediatric medicine. All children go through it, typically starting at about 6 months of age, and the current list of signs and symptoms attributed to the eruption of teeth in infants is long and varied, with most if not all of them inaccurate if not highly suspect. And although teething as a concept may seem rather commonplace, it is an entity with an interesting history and a frequent impetus for exposing young children to ineffective and even risky treatments.
What is teething?
Simply put, teething occurs when a tooth nears completion of its journey into the oral cavity, a journey which begins early in fetal development. The tooth erupts though the gum, often preceded by a small lump. Occasionally there can be a larger eruption cyst, and the area may appear somewhat bluish and swollen from bleeding into the tissue, but this is uncommon. The most widely accepted duration of a bout of teething is a roughly 8 day period, with tooth emergence generally felt to occur on day 5. The whole process usually takes about two years, with an average of one tooth emerging each month until the full complement of 20 baby teeth are present. (more…)
If there is one aspect of “alternative” medicine that both critics and fans should agree on, it’s that products should be manufactured to high standards. What’s on the label should accurately describe what’s in the bottle. Product quality standards are essential, whether you’re using herbs or drugs. And when it comes to ensuring the products we buy are of high quality, we’re all effectively reliant on regulation to protect us. As a pharmacist, I can’t personally verify that each tablet in your prescription contains the active ingredient on the label. I am dependent on a supply chain that may stretch around the world. While the product manufacturer may be reputable, it’s only a regulator that can realistically verify and enforce production to strict quality standards. The same cannot be said for products like supplements and herbs which are regulated differently than drugs, and held to different, and in some cases, weaker standards. A weak regulatory framework, which doesn’t hold manufacturers to account, would be expected to result in a product of lower quality. And that’s exactly what you see when you look at supplements on the market today.
A man of science rises ever, in seeking truth; and if he never finds it in its wholeness, he discovers nevertheless very significant fragments; and these fragments of universal truth are precisely what constitutes science.

I almost never have to search for material for this blog. The Secret always seems to provide topics. Subject matter appears unbidden out of the ether. But not this week. I enjoy deconstructing the nonsense of SCAM papers or blog entries more than any other type of blog entry. Perhaps the glee that last week’s entry provided had to be countered by some kind of cosmic balancing mechanism. Although the rational part of my mind objects to the personification of random existence, I suppose the Universe just does not want me to have that much fun two entries in a row. Probably explains why I have a viral URI and my brain has slowed almost to the point of functional inactivity. There is no shortage of SCAMs to write about, they are just not created equal in their ability to generate a passionate rant. (more…)
Augusto Odone is an Italian economist best known for his son, Lorenzo, after which Odone named the oil that he helped develop to treat his son’s neurological disease. Lorenzo’s oil was the subject of a 1992 movie starring Nick Nolte and Susan Sarandon, and of course what most people think they know about the story they learned from the Hollywood version.
This past week Augusto Odone died at the age of 80, prompting another round of media reporting about Lorenzo’s oil.
Probably because of the Hollywood movie, this story more than any other is an iconic example of the disconnect between the simple narratives the media love to tell (and we love to tell ourselves) and the more complex reality.
The basic facts of the story are not in dispute. Lorenzo Odone, son of Augusto and his wife, had a neurological disease known as X-linked adrenoleukodystrophy (X-ALD). This is a devastating genetic disease in males, with two basic forms. Childhood onset tends to progress rapidly and typically death occurs by age 10, although lifespan can be increased if an early bone marrow transplant is given. In adult onset, symptoms may not appear until adulthood, and then tends to progress more slowly, over decades. Some boys with the X-ALD gene do not develop clinical findings. Women are carriers, with partial protection from their second X chromosome. About half of female carriers become symptomatic, with the slower adult form of the disease.
Science-Based Medicine authors tend to focus attention on practices that misuse or ignore the tools of science. This is not a criticism. As a daily reader and occasional contributor, I recognize that shining a light on pseudoscience is a critical part SBM’s mission. It is what brings me back day after day. Sometimes, however, it is nice to highlight what real science and real evidence can do.
In my world of treating patients with retinal disease, a revolution has taken place over the past few years. The most aggressive form of macular degeneration has been transformed from a relentlessly progressive, disabling disease to one which can be tamed with medication. Now, patients diagnosed with exudative macular degeneration can expect stabilization and even improvement in vision.
It is a story worthy of a Hollywood movie. Start with a reluctant hero; add controversy, Wall Street, politics, and most important of all, a happy ending.
While I’m now two full decades out of pharmacy school, I am occasionally invited to return to give a lecture or facilitate a workshop. Pharmacy education has changed a lot since the 1990′s. For me, pharmacy was a Bachelor’s degree program you started right out of high school. Today, students must have a few years of university completed before they can apply (some already have one degree), and the more common degree granted is doctorate-level, the Pharm.D. The clinical training has been bulked up and the practical training is much more rigorous. I see all this as positive change, as the practice of pharmacy has changed along with the education standard. The era of the “count, pour, lick and stick” pharmacist is disappearing as these tasks are automated or delegated to others. Today’s pharmacist has the opportunity to deliver care in different ways, including new roles like vaccine provider, and medication review/drug therapy optimizer. Many find positions that allow them to leverage their drug-related expertise to other areas of the healthcare system.
With pharmacists’ knowledge of drug products it should not be a surprise that they are consulted widely for advice by patients as well as other health professionals. Public surveys on trust show pharmacists lead other health professionals on this measure. It should also not be a surprise that pharmacists can be quite influential in shaping drug use, particularly when it comes to advice about complementary and alternative medicine (CAM), especially when it is used with conventional, science-based drug treatments. After all, drug stores are becoming (to my professional embarrassment) purveyors of all forms of CAM, ranging from homeopathic “treatments” through aisles of herbal remedies, vitamins, and other supplements. One pharmacy I used to work at sold copper bracelets, magnets, salt lamps, ear candles, homeopathic “first aid” kits, and detox packages that were purported to “balance” your pH. If there was a plausibility limit to what this pharmacy would sell, I never saw it reached. I gave the best science-based advice I could, but eventually left due to my concerns about what was on the shelves. But my time in that setting showed me the opportunity to improve care: the pharmacist is well positioned to advise on the evidence for or against any particular treatment, as well as the describe the potential risks with combining CAM with evidence-based treatment approaches.
