No, the HPV vaccine does not cause promiscuity

Vaccine Smile

Today’s post isn’t about the flu vaccine, but that vaccine played a part in bringing you today’s topic. It seems that this year’s vaccine is a mediocre match for the circulating strains of influenza, and I was one of the unlucky ones in whom it didn’t appear to provide much protection. After spending several days effectively bedridden, I still feel like I’m emerging from a cognitive fog. So today’s post will be short. In the midst of my own infection, the results of a new study were announced that examined the effects of HPV vaccination on indicators of sexual behaviour in adolescent girls. I admit to being a bit dumbfounded by the topic when I heard it, and I initially thought I had heard the research question incorrectly. After all, the answer seemed (to me) so clearly self-evident, I questioned if this was an ineffective use of research dollars. This question seemed as pertinent as continuing to study the relationship between vaccines and autism: there is little reason to think there would be any causal relationship. But surveys of parents show this is a real concern for some. And now we have an answer grounded in real-world evidence. (more…)

Homeopaths Threaten Public Health Selling Sugar Pills as Vaccine Alternatives

Alternative medicine is ascendant in Canada. From the dubious remedies that are now stocked by nearly every pharmacy, to the questionable “integrative” medicine at universities, there’s a serious move to embrace treatments and practices that are not backed by credible evidence. Canada’s support for alternative medicine, and for its “integration” into conventional health care is arguably is worse than many other countries. Canada’s drugs regulator, Health Canada, has approved hundreds of varieties of sugar pills and declared them to be “safe and effective” homeopathic remedies. Some provinces are even moving to regulate homeopaths as health professionals, just like physicians, nurses and pharmacists. Given the regulatory and legislative “veneer of legitimacy” that homeopathy is being granted, you can see how consumers might be led to believe that homeopathic remedies are effective, or that homeopaths are capable of providing a form of health care. The reality is far uglier, and the consequences may be tragic. Canadian homeopaths are putting the most vulnerable in society at risk by selling sugar pills to consumers, while telling them that they’re getting protection from communicable diseases. (more…)

Naturopathy vs. Science: Autism

asperger's autism

Just when I thought I was out, they pull me back in. My blogging plan was to take a break from my series of naturopathy versus science posts, where I’ve been contrasting the advice from naturopaths against the scientific evidence. From a blogging perspective, naturopathy is a fascinating subject to scrutinize as there is seemingly no end of conditions for which naturopaths offer advice that is at odds with the scientific evidence. From a health care perspective, however, reading the advice of naturopaths is troubling. Naturopaths promote themselves as health professionals capable of providing primary care, just like medical doctors. And they’re increasingly seeking (and obtaining) physician-like privileges from governments. Naturopathy seems to be getting an easy ride from regulators, despite a lack of evidence that shows naturopathy offers anything distinctly useful or incrementally superior to science-based medicine.

Defining the scope of “naturopathic” treatment is difficult. Naturopaths offer an array of disparate health practices like homeopathy, acupuncture and herbalism that are only linked by the (now discarded) belief in vitalism – the idea we have a “life force”. From this philosophy can sometimes emerge reasonable health advice, but that has little to do with the science or the evidence. As long as it’s congruent with the naturopathic belief system, it’s acceptably “naturopathic”. In past posts I’ve looked at the naturopathic perspectives on fake diseases, infertility, prenatal vitamins, vaccinations, allergies and even scientific facts themselves. An advertisement passed to me this week promoted a naturopath who claims to treat pediatric conditions like ADHD and learning disabilities: (more…)

Naturopathy vs. Science: Fake Diseases

Low body temperature! Do you have Wilson’s Temperature Syndrome?

This is another in an irregular series of posts that puts the statements of naturopaths up against the scientific evidence

How are you feeling today? Tired? Lethargic? Chilled? Lacking energy? Is it the nature of life – or is it something more serious? If you consult with a naturopath, you could walk out diagnosed with something called Wilson’s Temperature Syndrome. But the naturopath would be wrong, because Wilson’s Temperature Syndrome is a fake disease.

One of the hallmarks of alternative medicine is the “fake disease”. Fake diseases don’t actually exist – they are invented without any objective evidence showing that they are real. Fake diseases tend to emerge from vague symptoms which can’t be attributed to a specific medical diagnosis. This is not to say what patients are experiencing isn’t real – the issue is the diagnosis, and the practitioner making the call. As has been pointed out by other SBM contributors, it’s understandable to want reasons and answers when you have debilitating symptoms. But symptoms need to be studied in rational and objective ways in order to understand the underlying illness – call it the “root cause” if you prefer. The diagnosis guides the treatment plan, so getting a diagnosis right is essential. While a group of vague symptoms might lead a medical doctor to run tests to rule out serious illness, alternative medicine providers already know the underlying problem. It’s your Chi. Your energy fields. Your diet. Whatever it is, it’s usually your fault. Adrenal fatigue is a fake disease. So is multiple chemical sensitivity, and Morgellons (delusional parsitosis). “Chronic” Lyme disease is another fake disease. Rather than offer a guide to proper care, a fake disease is a distraction from the truth. (more…)

Lessons from the dubious rise and inevitable fall of green coffee beans

Green-Coffee-Bean-BOGUS

News this week that a randomized controlled trial of green coffee bean (GCB) has been officially retracted from the medical literature signals what is hopefully the end to one of the most questionable diet products to appear on the market in years. Plucked from obscurity and then subjected to bogus research, it’s now clear that the only people that actually benefited from GCB were those that profited from its sale. GCB had some powerful boosters, too. Once it became one of Dr. Oz’s “miracle” weight loss cures, sales exploded following two hype-filled episodes. Oz even did a made-for TV clinical trial with GCB, ignoring the requirements for researchers to obtain ethical approvals before conducting human subject research. Oz’s promotion of GCB was so breathless and detached from the actual evidence that his actions were subsequently eviscerated by Senator Clair McCaskill during televised hearings on weight loss scams. It’s a long, sordid, ugly and yet entirely predictable story. (more…)

Naturopathy vs. Science: Infertility Edition

This is another post in the naturopathy versus science series, where a naturopath’s advice is assessed against the scientific literature.

It’s Naturopathic Medicine Week in the United States, so it’s time for another look at the alternative medicine practice that a friend of the blog likes to call the One Quackery to Rule them All. Naturopathy is an oddity among alternative medicine, because it’s a hodgepodge of other practices linked by an underlying belief in vitalism: the pre-scientific notion that living things have a “life force”. Vitalism disappeared from medicine when Wöhler synthesized urea in 1828, yet the belief in vitalism is a central tenet of naturopathic philosophy. Naturopaths liken themselves to primary care providers comparable to family physicians (general practitioners) but their practices are quite different: rather than making decisions based on scientific evidence, naturopaths pick and choose based on what they feel is congruent with their vitalistic philosophy, sometimes despite good scientific evidence that shows they are wrong. For example, homeopathy is an alternative medicine practice that is very popular with naturopaths. It is an elaborate placebo system where “remedies” contain no medicinal ingredients: they are literally sugar pills. There is no demonstrable medical effect from homeopathy, and so it isn’t part of science-based medicine. Yet homeopathy is a “core clinical science” for naturopaths, and the practice of homeopathy is part of their licensing exam.

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…)

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…)

Naturopathy vs. Science: Facts edition

Lalalala

This is another post in the naturopathy versus science series, where a naturopath’s advice is assessed against the scientific literature.

When you think medicine, your first thought may be “physician”. But the practice of medicine today is a collaboration, as few health professionals, even physicians, can deliver health care completely independently. As a pharmacist I’ve worked closely with physicians, nurses, and other health professionals my entire career. Collaboration starts early, and the setting is usually the teaching or academic hospital, which is always crawling with students, interns, and residents from all professions. Teamwork and trust are essential. In order for different professions to work effectively together, there has to be a common foundation. For medicine, that foundation is science. From basic science principles through a common understanding of fields like biochemistry and physiology, health professionals all work from the same basic understanding about how the body works and what the principles of medicine actually are. If I give a recommendation to a physician or a nurse, I’m basing that assessment on an evidence base that we both rely on. It’s not “pharmacist evidence” versus “physician evidence”, it’s “medical evidence”. This is reality-based healthcare. (more…)

Naturopathy vs. Science: Prenatal Vitamins

Pregnant1

This is another post in the naturopathy versus science series, where a naturopath’s medical advice is assessed against the scientific evidence. Today’s topic is brought to you by Toronto naturopath Shawna Darou, who recently published her evaluation of prenatal vitamins.

Vitamin supplementation is unnecessary for the vast majority of people. You wouldn’t know this walking through a drug store, where you’ll usually find an entire aisle packed with supplements. Alternative health providers like naturopaths tend to be strong supporters of supplementation, but this advice seems to be based mainly on the belief that “vitamins are magic” rather than good science. The best research hasn’t established a strong evidence base for taking  supplements. We definitely need vitamins in our diet to live. But that’s where we should be getting those vitamins – from our food, instead of from pills. If you eat a reasonable and balanced diet, and have no medical conditions that require special consideration, vitamin supplementation won’t offer meaningful health benefits. In the absence of any deficiency, vitamin supplements seem to be useless at best and harmful at worst. (more…)
