If you don’t buy this supplement for your child, you’re a terrible parent

kids-dha-cerebrum-small

The supplement industry wants you to buy their products, and they’re not above using a little parental guilt to make you into a customer. In the photo above, the promoter is my local pharmacy, where the large window display caught my eye:

Give your Child The Tools to SUCCEED in School!

Who doesn’t want their child to succeed? And if you knew a supplement could give you or your child a learning edge, would you consider it? I’d imagine many do. Supplements have a remarkable health halo. As a pharmacist myself, I’ve noticed this when speaking with patients – few consumers identify any potential risk or downsides to supplement use. Some don’t even think of them as medicine at all. The marketing has resonated: Supplements are perceived as “safe”, “natural” and “effective”. But whether you’re giving your child a prescription medicine to treat attention deficit hyperactivity disorder, or you’re giving a supplement to “improve focus and brain function”, you’re still administering a chemical substance to a child with the intent of changing brain function. We’d probably think twice before pouring an unknown substance in our car’s gas tank, especially one claimed to boost performance. We’d probably ask for some evidence that it works, and some assurance it wouldn’t harm our vehicle. A decision to use a drug or supplement in a child deserves just as much consideration of benefits and risks. (more…)

Rationalizing the Ridiculous

410px-Chinese_barefoot_doctor_performing_acupuncture

Pictured: Cutting-edge medicine

I remain flummoxed. How do physicians and health care systems, trained in all the sciences that lie at the heart of medicine, justify the use of pseudo-medical interventions with no basis in reality? Rationalization. Making excuses:

a defense mechanism in which controversial behaviors or feelings are justified and explained in a seemingly rational or logical manner to avoid the true explanation, and are made consciously tolerable – or even admirable and superior – by plausible means.

Rationalization of the ridiculous comes in many forms. It has been said that it is a mark of a first rate intelligence to able to hold two contradictory ideas in the mind at the same time and still retain the ability to function. Clever as it is, I suspect the opposite is true. (more…)

Missouri tackles primary care shortage with “assistant physicians”

Medical school clinical training

Medical school clinical training

A new law in Missouri will allow medical school graduates who have not completed a residency to practice in underserved areas. They will be able to call themselves “doctor” but will be licensed as “assistant physicians” with significant limitations on their practice. (The first link is to Senate Bill 716, the bill that was passed and signed by the governor. It covers several subjects, so you will need to skip to page 8 to find the portion we’re discussing.)

The Missouri State Medical Association supports the new law and helped draft the original bill. It is designed to address the state’s critical need for primary care physicians – 40% of Missouri’s population lives in underserved areas but only 25% of the state’s physicians practice there, according to a 2009 survey. Underserved areas have high poverty rates, high infant mortality, large senior populations and fewer primary care physicians per capita. (more…)

Only two months until Skepticon

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.

So give. Give until it hurts. Or buy swag. Or both. And if you’re planning on going, register now instead of later. You’ll be glad you did.

Fluoride: Still Not Poisoning Your Precious Bodily Fluids!

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?

i-stopped-using-flouride-and-you-should-too

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.

Legislating Ignorance

Child-GUN

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.

Side effects may include liver failure

Liver

“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 SCAMs

ebola-virus

Click to embiggen. Transmission electron micrograph of an Ebola viral particle, by Dr. Frederick Murphy (1976), from the Centers for Disease Control and Prevention’s Public Health Image Library (PHIL), with ID #1833.

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.

Homeopathy

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…)

CAM and Headaches

Acupuncture needling

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 Touch to Fear: Chiropractic and the Newborn Baby

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.
