The public is often left to fend for themselves in the marketplace of medical devices and health aids. Current regulations in most countries are inadequate to prevent grossly misleading claims in advertising and to provide adequate evidence for safety and effectiveness for products on the market. So it is helpful for consumers to be aware of the red flags for dubious devices to watch out for.
I came across this ad for The Rebuilder, which purports to be a treatment for painful neuropathy. About 2.4% of the population has some kind of peripheral nerve damage (neuropathy), which means there are about 7.2 million Americans with neuropathy. In most cases there is no cure (although there is effective treatment for some of the symptoms of neuropathy) so it is not surprising that neuropathy is a common target for questionable treatments and devices.
The ad is full of misleading or unsupported claims and blatant misinformation and provides an excellent example of the many features of quackery marketing to look out for.
Some people are very invested in the idea that thimerosal in vaccines causes autism. They have looked and looked, but have been unable to find enough credible evidence to convince the scientific community. Thimerosal was removed from US vaccines several years ago, and you might have thought that would end the debate. It didn’t. The spotlight has shifted to other countries that still use thimerosal-preserved vaccines, such as Peru.
Anti-vaccine activist David Kirby said,
If thimerosal is one day proven to be a contributing factor to autism, and if U.S. made vaccines containing the preservative are now being supplied the world over, the scope of this potential tragedy becomes unthinkable.
The anti-vaccine website Age of Autism accuses US policy of
[making]…Kirby’s nightmare suggestion a reality. U.S. vaccine manufacturers have continued to ship thimerosal containing vaccine formulations all over the world, in effect offering a defiant double standard of mercury risk for infants from rich countries as compared to poor countries. (more…)
THE ZOMBIE RISES AGAIN
Vitamin C as a treatment for cancer is back in the news again.
I’m not surprised. This is one therapy favored by advocates of “alternative” medicine that keeps popping up periodically (seemingly every couple of years or so). This latest bit of news has turned up almost right on time after the last time there was a push for rehabilitating vitamin C as a cancer cure a couple of years ago. Back in the spring of 2006, there were two studies published (more on them later) which were touted by the “complementary and alternative medicine” (CAM) crowd as evidence that Linus Pauling was supposedly vindicated. A little less than two weeks ago, an animal study was published suggesting that high-dose intravenous vitamin C had antitumor activity in mouse models. A couple of weeks prior, there had also been published a phase I clinical trial that showed that megadoses of IV ascorbate were safe and well-tolerated in cancer patients if they were appropriately screened for renal disease. Given the latest studies of this particular modality against cancer, it seemed like an opportune time for me to examine this new evidence and ask the question: Has Linus Pauling been vindicated?
I’ll cut to the chase. The short answer is: Not really, with the qualification that it depends on what you mean by “vindicated.” The long answer follows.
“The graveyards are full of (unvaccinated) men.” Charles de Gaulle, modified by the author.
We live longer than anytime in history. Our long lives are due in large part to good nutrition, sanitation, and vaccines.
There have been numerous posts here and elsewhere about the vaccine deniers, primarily focused around the modern myth that vaccines cause autism.
That is not the topic of this post. Instead, I am going to take a brief tour of the childhood vaccines and review the morbidity and mortality caused by vaccine preventable diseases and the efficacy of the vaccines in preventing these diseases. With the brouhaha surrounding vaccines it is beneficial to step back and contemplate the death and misery that the vaccine preventable disease have caused and continue to cause.
In the interests of full disclosure, I am an Infectious Disease doctor. I make a living from treating diagnosing and treating infections. I don’t make dime one if people do not get infected, so I am against any and all vaccines as they cut into my bottom line (2).
The internet is arguably the ultimate expression of democracy and the free market. For the cost of internet access anyone can pull up a virtual soap box and preach to the world. There are no real gatekeepers, and the public can vote with their search entries, clicks, and links. Every point of view can be catered to and every special interest satisfied. Type in any obscure term or concept into Google and see how many hits you get (“banana farming” yielded 1,470,000 hits).
There is potentially a downside to this as well, however. Because there are websites fashioned for every opinion and perspective no one has to venture far out of their intellectual comfort zone. Virtual communities of like-minded individuals can gather and reinforce their prejudices, and to varying degrees keep out contrary opinions. This is harmless when dealing with aesthetic tastes, but can be stifling to intellectual discourse.
On the other hand defining the mission, scope, and character of a blog, website, or forum is necessary to some degree. Every site does not have to be a free-for-all. If biologists want a forum to politely discuss biological topics in a collegial fashion they have the right to create a virtual space in which to do that, and whoever owns and operates the site has the right to mandate whatever rules they wish. Allowing political activists to overrun the site and hijack the conversation would be counterproductive. Like most things a healthy balance probably works best.
Polypharmacy essentially means taking too many pills. It’s a real problem, especially in the elderly.
A family doctor gives an elderly patient one pill for diabetes, another for high blood pressure, and another to lower cholesterol. The patient sees a rheumatologist for his arthritis and gets arthritis pills. Then he sees a psychiatrist for depression and gets an antidepressant. He takes a sleeping pill. He takes a laxative. He buys some over-the-counter cold medicine and Tylenol. Then he goes to his local GNC store and buys a smorgasbord of vitamins, minerals, supplements and herbal products. It would be surprising if some of these didn’t interact with each other to cause some problems.
One doctor may not know what the other doctors have prescribed. The patient may not think to tell his doctors about the non-prescription products he’s taking. Or he may not want to admit it for fear the doctors will disapprove. (more…)
The first thing that struck me about him was that he was orange.
It was not a shade of orange I had ever ever encountered before in a patient. It was a yellowish orange, an almost artificial-looking color. At first I wondered if he was suffering from liver failure with jaundice, but this orange was just not the right shade of yellow for jaundice, and his sclerae were not yellow. I also considered whether he was suffering from renal failure, but the orange color of his skin didn’t quite match the rather coppery color that some patients suffering from longstanding renal failure necessitating dialysis sometimes acquire. I was puzzled. His chart said that he was being admitted for surgery for rectal cancer. So I sent the intern in to get the story, do the history and physical, and get him all plugged in for his bowel prep. Believe it or not, there was actually a time when it was not all that uncommon for patients to come into the hospital the night before major abdominal surgery in order to undergo a preoperative bowel prep, rather than being forced by their insurance companies to undergo the torture of drinking four liters of the purgative known as Go-Lytely–a misnomer, if ever there was one!–at home and spending the next several hours having to rush periodically to the toilet, waiting in vain for the liquid exploding out of their hind end to run clear.
My Discussion with Dr. P
After last week’s post, Dr. Peter Moran answered with more salient points. I’ll spend this week discussing those, because I share Dr. Moran’s “interest in examining the kind of messages we are putting out.” Acknowledging the inequality inherent in his not being the blog author, I’ll offer the last word to Dr. Moran by ending this series* and letting whatever comments he may have in response to today’s post be the last, at least for now.
Here is Dr. Moran’s response to my response:
Medicine’s ethics and basis in science hang by a thread at times. At least in the US of A. I will present a few examples and illustrate them with correlates from other fields in which decisions with wide effects are sometimes made by the whim of one person. And that’s not just the declaring of war or whatever we call it these days.Start with an anecdote of mine from the mid-1970s or so. I somehow got involved in a dispute with the staff of then Gov. Jerry Brown over his proposal to de-license medical practice. He sent out early holistic medicine vibes and viewed health and medicine as fields open to anyone to practice by simply hanging out a shingle. I asked to meet with my state assemblyman and complained about the situation. I stated that physicians determined what medical practice is. He smiled benevolently and broke the news. “No, doc, we (in state government) do.“
I immediately recognized what he was saying. All licensure is granted by the state, and all regulations and laws referring to each occupation’s license are determined essentially by a majority vote and a governor’s signature. All those heroes in the history of medicine and science not withstanding. It was an awakening.
Jerry Brown’s vision did not materialize and he came to recognize holistic and alternative medicines as so much goofy stuff and quackery, as he later confided at a fund-raiser (yes, I went.)
Three days ago, I published a disapproving commentary about a disappointingly credulous and misinformation-laden article published on Medscape about the human papilloma virus vaccine Gardasil. The article was clearly biased, and, worse, it quoted Oprah’s favorite woo-loving gynecologist Dr. Christiane Northrup parroting germ theory denialism and the myth that Louis Pasteur “recanted” on his deathbed. All in all, it was a terrible article, far below the usual standards that I would expect for Medscape.
Yesterday, multiple people pointed out to me and I have seen at the blog Holford Watch that the original link to the Medscape article now leads to a “page cannot be found” error. Apparently, Medscape has pulled the article. At least, that’s the only explanation I can think of. Maybe Medscape has some shame after all.
Actually, I was disappointed to see the pulling of the article in this manner because this is not the way to go about it. Rather than admitting it made a mistake in not adequately fact-checking the article, including ignorant quotes by Dr. Northrup, and–let’s face it–publishing such a shoddy article in the first place, Medscape has instead apparently taken the path of least resistance and simply quietly pulled the article, perhaps hoping that no one will notice. A better course would have been to pull the article (it didn’t belong on Medscape, that’s for sure), but leave the original link to the article, replacing the article with an explanation why the article was pulled. By taking what strikes me as the cowardly way out, Medscape has, if anything, lowered rather than raised my opinion of it. Although I’m happy to see that its editors apparently have a sense of shame, I’m disappointed that they chose such a sneaky way to correct their mistake. It’s always better to own up to mistakes when you fix them.
