I don’t recall if I’ve mentioned this before, but I will be speaking at Skepticon in November. (Holy crap, that’s just over two months away. I’d better get my talk ready. It’ll be about the central dogma of alternative medicine. Or some such medically-related topic.) In any case, now’s crunch time, the time of year when Skepticon’s fundraising needs to go into high gear, given that the bills are coming due for the conference.

We dentists are an evil group of sociopaths. When we’re not trying to kill you or give you chronic diseases such as multiple sclerosis with our toxic mercury saturated fillings, we are advocating for the placement of rat poison/industrial waste (i.e. fluoride) in your water supply by our governmental overlords. What is up with us?
The problem is, we’re failing miserably. Even after more than 150 years of placing silver amalgam restorations in our patients, thereby saving untold numbers of teeth, reducing pain and suffering, and improving chewing ability for millions upon millions of people, there is still no evidence worth a damn that shows any correlation or causative effects for any known disease or condition. And with fluoride, after adjusting fluoride levels in municipal water supplies throughout the U.S. and in many places world wide for over sixty years, after adding fluoride to toothpastes and mouthwashes, and giving fluoride treatments to patients in our offices, the only nefarious result we have obtained is the significant reduction of dental decay with its concomitant savings of billions of health care dollars and untold pain and suffering for our patients. Man, we can’t do anything right.
Now, with the help of the American Academy of Pediatrics (AAP), there’s a new strategy.
Science is under attack, and not just from anti-vaccine celebrities and parents with degrees from Google University. Scientific illiteracy is being woven into the very fabric of our society through legislative assault. If you dismiss this as alarmist hyperbole, you haven’t been paying close enough attention.
Every day thousands of pediatric health care providers throughout the country provide safety advice to patients and their parents during routine health maintenance visits. As part of this important routine we ask a series of standard questions to assess the safety of our patients’ environment. Some of these questions are easy and straightforward, and some are more personal and potentially awkward for patients and their parents, including questions pertaining to sexual practices and preferences and psychosocial history. An important series of questions focuses on potential hazards in the home, such as how toxins and medicines are stored, how pools are secured against curious toddlers, and whether there are guns in the home and how they are stored and secured. Parents are usually appreciative of the advice we provide, and thankful for our concern and attention to these issues. Occasionally patients or parents are taken aback by some of these questions, and very rarely they prefer not to answer them (in my 20 years in practice, I can recall only one time this has occurred). We ask these questions because accidental injuries and deaths are common occurrences in the pediatric population, and there is good evidence that patients tend to follow the advice we provide our patients.

“Safe and natural.” It’s a marketing phrase attached to dietary supplements that’s often accepted as self-evident. The marketing works. Supplements have a strong health halo. But evidence suggests that this reputation may be undeserved. Not only are there continued questions about whether most supplements have any health benefits whatsoever, there is also evidence that they can be harmful. We can’t even be confident that what’s on the label is actually in the bottle. Just two days ago I was notified of another long list of supplements and remedies that the FDA had identified that were contaminated with prescription drugs. These warnings about products sold as supplements appear regularly. Some time ago I asked, “What’s in your supplement?“, and noted that contamination and poor product quality standards continue to raise questions about whether supplements can be used safely at all, because the harms, when they occur, can be catastrophic. No matter how you feel about their efficacy, we can probably all agree no consumer should lose an organ from taking a health supplement. But it can happen. (more…)
Ebola, like all diseases, is an opportunity for some to offer up curious treatments. Here is a brief budget of Ebola-related SCAM (supplements, complementary and alternative medicine) and a few Dug the Dog digressions.
Reality seems valueless by comparison with the dreams of fevered imaginations; reality is therefore abandoned. ~ Emile Durkheim. Homeopath?
In its classic form, as promulgated by Hahnemann, homeopathy is divorced from the modern understanding of medical and chemical reality. I can cut Hahnemann a little slack since he came up with his fictions at the end of the 18th century. But I would think that even a modest understanding of chemistry and physiology would suggest that homeopathy is 100% pure bunkum. But homeopaths are nothing if not inventive. Since Hahnemann’s time they have come up with a remarkable number of variations on their nonsense. The motto “you are only limited by your imagination” must have had homeopaths in mind and they have fevered imaginations. Who knows what they could invent if they only had a box. There are nosodes, the homeopaths answer to vaccines. Of course, it is an answer that would be wrong on any reality-based exam. Nosodes are the vaccines of the homeopathic world, only without efficacy. I have written about nosodes in the past.
[A nosode] is a homeopathic remedy prepared from a pathological specimen. The specimen is taken from a diseased animal or person and may consist of saliva, pus, urine, blood, or diseased tissue.
and they are usually diluted to between 30 and 300 C. (more…)
A recent editorial entitled “CAM in the Real World: You May Practice Evidence-Based Medicine, But Your Patients Don’t” published in Headache: The Journal of Head and Face Pain by Robert Cowan, a headache specialist, addresses the use of complementary and alternative medicine (CAM) in the treatment of headaches. Unfortunately he propagates many common misconceptions about CAM in the article.
I do agree with one point – physicians need to be more aware of CAM treatments and their patients’ use of them. We should be directly asking our patients about such use, in a non-judgmental way, and we should be familiar enough with common CAM treatments so that we can provide knowledgeable guidance to our patients.
Cowan begins by, in my opinion, grossly exaggerating the current popularity of CAM. He writes:
As much as 82% of headache sufferers use complementary and alternative approaches.
The reference he cites, however, states:
Adults with migraines/severe headaches used CAM more frequently than those without (49.5% vs 33.9%, P < .0001); differences persisted after adjustment (adjusted odds ratio = 1.29, 95% confidence interval [1.15, 1.45]). Mind–body therapies (eg, deep breathing exercises, meditation, yoga) were used most commonly.
Only 4.5% of adults with migraines/severe headaches reported using CAM to specifically treat their migraines/severe headaches.
A significant part of my job as a pediatric hospitalist involves caring for newborns. It is arguably the best thing that I get to do as a physician, even if I do at times prefer the increased intellectual stimulation of the ill hospitalized child. While seeing newborns, I am almost always surrounded by happy and appreciative parents, grandparents and whoever else is invited to meet and greet the new arrival because the babies are almost always healthy. In fact, and not that I really care (sniff, sniff), the parents of newborns are with rare exception the only caregivers that ever thank me at discharge.
Unfortunately, sometimes I am called upon to assist babies that are having difficulty transitioning into the outside world for a variety of reasons. These reasons can range from the fairly minor and transient to the catastrophic. And despite our advances in the understanding of neonatal pathophysiology and in medical technology, there remain newborn infants that cannot be saved or who have severe lifelong deficits caused by their illness or injury. This will likely always be the case, especially if unqualified professionals continue to involve themselves in either the delivery or the care of babies.
Over the course of 11 years of practice, and after having seen thousands of both perfectly healthy and severely ill newborns, I have acquired a skill set which allows for the recognition of a baby in trouble and the ability to respond appropriately. All pediatricians and family doctors strive to develop this, particularly if they see patients in the newborn nursery, although I imagine none, including myself, would claim to have perfected this “art”. Newborn medicine can be very challenging for many reasons, not the least of which is the significant overlap of the presenting signs and symptoms of many serious conditions, with even normal baby behavior sometimes mimicking potentially life-threatening pathology.

It’s an excellent business model. The only real infrastructure you need is a website, and you can have a custom site made for $5-10 thousand. Then you just have the monthly bandwidth charges. The rest is just e-marketing, which can be done for free, or the cost of some e-mails lists. After that, the money just comes rolling in.
The best part is that other people do all the actual work. All you have to do is charge them for publishing on your open-access online journal.
What you are selling is essentially scientific/academic fraud.
Unfortunately, this is a good business model, even though it is a terrible scientific model, and so it has proliferated. We may be living in the heyday of dubious open-access scientific journals.
The open-access format itself is not a bad one, and there are some very successful and respected open-access journals, such as the PLOS journals. The idea is that, instead of charging a subscription in order to gain access to published articles (in print or online), the articles are open-access, but authors pay a fee to have their work published.
Old bad studies: Fantastical autopsy results
I found the following quote at “Chiropractic care can treat more than just bad backs” (FYI. Chiropractic can’t):
Luse references a study published in The Medical Times authored by Dr. Henry Windsor [sic], M.D. that showcases the correlation of spinal health to overall wellness. Windsor dissected 75 human cadavers to investigate their causes of death. The study showed that 138 of the 139 diseases of the internal organs that were present were in connection to the misalignments of the vertebrae.
But I was intrigued. So I went to the video tape. Well, the PDF.
It is an interesting read by a physician who was looking for an association between curvature of the spine and visceral pathology.
He had 50 corpses, age unknown, that he dissected, looked at the spine for curvature and then looked for pathology in organs in the same distribution of sympathetic nervous system as the level of the spine curvature.
A small but increasing number of parents are refusing vitamin K injections for their newborns, an intervention recommended since 1961. This is yet another example of the difference between a science-based and philosophy-based approach to medicine. Science has given us the tool of knowledge, and in medicine that knowledge can have very practical applications.
The term “vitamin” was coined in 1912 by the Polish biochemist Kazimierz Funk. A vitamin is an organic nutrient that an organism requires in small amounts but cannot synthesize in adequate amounts and therefore must obtain from the diet. Knowledge of specific vitamins, their food source, and their biochemical activity in the body, has allowed medical scientists to cure many serious nutritional diseases, such as scurvy, rickets, and blindness.
The Vitamin K family are derivatives of 2-methyl-1,4-naphthoquinone, a fat-soluble molecule. It is a cofactor necessary for the formation of factors that function in blood clotting and in bone formation. The primary effect of vitamin K deficiency is therefore bleeding. Infants are at risk for vitamin K deficiency because this molecule does not cross the placenta well. Infants are therefore born relatively deficient in vitamin K. Further, breast milk contains little vitamin K (regardless of the mother’s diet) so infants are at risk for vitamin K deficiency until they start eating solid food at around 6 months (see Clay Jones’ post on the topic here).
