What is in a prenatal vitamin? Why do most doctors recommend them? Is there any evidence taking them is worthwhile? I decided recently that I would read through the ingredients of these vitamins, often touted as “essential vitamins and nutrients, crucial for the healthy development of your baby.” Hmmm. Does that mean eating traces of polyvinyl alcohol every day is beneficial?
The fine print ingredients of such brands as “One A Day”, “Centrum Materna”, “Rite Aid” and even the prescription only “Prenate Elite” are a confusing mess of milligrams, international units, RDA’s, and chemicals. As the makers of Centrum explain, “It is very challenging to formulate vitamins and minerals without the use of non-medicinal ingredients which serve to keep the product stable and to prevent the various ingredients from interacting.” They also find fault in the limited number of suppliers of the active ingredients in prenatal vitamins, and therefore claim substances like gelatin are difficult to avoid.
Let’s take a tour of the prenatal vitamin ingredient zoo. Read more »

If you google “low testosterone” you’ll see lots of ads for testosterone replacement. Some are from pharmaceutical companies that sell testosterone, others from obvious snake-oil salesmen.
Both types of ads list vague sets of symptoms, encourage you to believe that they are pathologic, and want to sell you something to make you better. For example, the pharmaceutical company Solvay gives you a handy guide for speaking to your doctor, and a quiz to see if you have “low T.” The quiz asks some questions that may be useful, but also asks very general questions about your sense of well being.

Any promoter of science-based medicine often faces the question: “What’s the harm?” What is the harm if people try treatment modalities that are not based upon good science, that are anecdotal, or provide only a placebo benefit? There are generally two premises to this question. The first is that most “alternative” placebo interventions are directly harmless. The second is that direct harm is the only type worth considering. Both of these premises are wrong.
The pages of Science Based Medicine (SBM) are filled with accounts of direct harm from unscientific treatments: Argyria from colloidal silver, death from chelation therapy, infection or other complications from acupuncture, burns from ear candleing, stroke from chiropractic neck manipulation — the list goes on. You can read anecdotal accounts of such harm on the website, whatstheharm.net.
Of course, as we often point out, harm and risk is only one end of the equation — one must also consider benefit. It is the risk-benefit ratio of an intervention that is important. But generally we are talking about interventions that lack any evidence for benefit, and therefore any risk of harm is arguably unacceptable. Read more »

I write a lot of critical articles. It’s nice to be able to write a positive one for a change. I received a prepublication proof of The Mayo Clinic Book of Home Remedies: What to Do for the Most Common Health Problems. It is due to be released on October 26 and can be pre-ordered from Amazon.com. Since “quackademic” medicine is infiltrating our best institutions and organizations, I wasn’t sure I could trust even the prestigious Mayo Clinic. I was expecting some questionable recommendations for complementary and alternative medicine (CAM) treatments, but I found nothing in the book that I could seriously object to.
It is organized alphabetically, starting with acne and airplane ear and progressing through bedbugs, boils and bronchitis, dandruff, depression and diabetes to warts, wrinkles and wrist pain. Each entry consists of (1) a description of the problem and its symptoms, (2) treatments you can try at home, and (3) when to seek professional medical help. It concludes with a short section on emergency medicine that covers anaphylaxis, bleeding, burns, CPR, choking, fracture, heart attack, poisoning, seizure, shock and stroke.
Nowhere does it mention acupuncture, chiropractic, energy medicine, or homeopathy. It gives good, clear guidance about when a health problem should not be treated with home remedies. Its recommendations about diet and exercise are solid. It doesn’t recommend anything that can’t be supported by published studies and common sense. When it recommends herbal remedies and dietary supplements, it is cautious about what it claims. For instance, glucosamine and chondroitin are listed for osteoarthritis, but they point out that further study is required and they say “because the supplements may help and appear to be safe, it may not hurt to give them a try.” Not exactly a strong recommendation.

There’s an AIDS epidemic in Africa, and efforts to fight it are hampered by the endemic social problems of that continent. Chief among them are the lack of sufficient modern health resources, the spread of destructive rumors and myths about HIV/AIDS, and even the persistence of HIV denial in Africa (although this last factor is better than in the past).
The World Health Organization (WHO) and the International HIV/AIDS Alliance are teaming up with the Traditional Health Practitioners Association of Zambia (THPAZ) to address the first problem –- the lack of health services.
Most Zambians use traditional healers for primary healthcare. The WHO has therefore decided to utilize traditional healers in the fight against AIDS. There are interesting pros and cons to this policy, but it must first be recognized that there is no ideal solution to the problem. The resources to provide optimal modern health care to treat and prevent HIV/AIDS (which would need to include a massive education program) in Zambia and the rest of Africa simply do not exist. One might argue that the world should provide those resources, but let’s put that issue aside and focus on what to do in the meantime. Read more »
