Clinical trials

One of the best things about blogging is that I don’t feel obligated to cover a topic completely in one post because I know I can always write another one or revisit the topic later. It also allows me to look at what I like to call “variations on a theme” of various kinds of…

One of my favorite television shows right now is The Knick, as I described before in a post about medical history. To give you an idea of how much I’m into The Knick, I’ll tell you that I signed up for Cinemax for three months just for that one show. (After its second season finale…

It is an article of faith among the antivaccine movement that vaccines are degrading the health of our children, such that vaccines cause autism, asthma, diabetes, and a number of other chronic diseases. You won’t have to look far on most antivaccine websites to find claims that today’s children are the sickest in history and…

The other day, I suddenly realized that it’s been a long time since I’ve written about the Polish expat doctor in Houston who treats patients with advanced brain cancer with a concoction that he dubbed antineoplastons (ANPs). I’m referring, of course, to Stanislaw Burzynski who, despite the fact that he has no training in medical…

Choosing Wisely three years on

I like to point out from time to time that arguably the most striking difference between science-based medicine (and the evidence-based medicine from which we distinguish it) and alternative medicine, “complementary and alternative medicine” (CAM), or (as it’s called now) “integrative medicine” is a concerted effort to change practice for the better based on science…

One of the things that feels the weirdest about having done the same job, having been in the same specialty, for a longer and longer time is that you frequently feel, as the late, great Yogi Berra would have put it, déjà vu all over again. This is particularly true in science and medicine, where…

When last I discussed the cruel sham that is the tide of “right-to-try” laws that has been flowing through state legislatures to become law over the last year and a half. “Right-to-try” laws, as I pointed out when I first noted the earliest ones being promoted in Colorado, Louisiana, Arizona, and Missouri, referring to them…

Earlier this week, the Nobel Prize in Physiology or Medicine was awarded to Youyou Tu for her discovery of the anti-malaria compound Artemisinin, as well as to William C. Campbell and Satoshi Ōmura for their discovery of a novel therapy for roundworm. Artemisinin, as some of you might know, is a compound derived from traditional…

I’ve written many times about how the relationship between the early detection of cancer and decreased mortality from cancer is not nearly as straightforward as the average person—even the average doctor—thinks, the first time being in the very first year of this blog’s existence. Since then, the complexities and overpromising of various screening modalities designed…

Yesterday, I wrote about how pediatric neurosurgeon turned presidential candidate Ben Carson is an excellent example demonstrating how the vast majority of physicians and surgeons, even highly accomplished ones admired as being at the top of their professions, are not scientists and how many of them are disturbingly prone to buying into pseudoscience. In Dr.…

NOTE: Orac is on vacation recharging his Tarial cells and interacting with ion channel scientists, as a good computer should. In the meantime, he is rerunning oldies but goodies, classics, even. (OK, let’s not get carried away.) Here’s one from all the way back in 2007. Notice how, the more things change, the more they…

Precision medicine: Hype over hope?

I am fortunate to have become a physician in a time of great scientific progress. Back when I was in college and medical school, the thought that we would one day be able to sequence the human genome (and now sequence hundreds of cancer genomes), to measure the expression of every gene in the genome…

How should we treat stage 0 breast cancer?

I’ve written more times than I can remember about the phenomenon of overdiagnosis and the phenomenon that is linked at the hip with it, overtreatment. Overdiagnosis is a problem that arises when large populations of asymptomatic, apparently healthy people are screened for a disease or a condition, the idea being that catching the disease at…

Acupuncture is a theatrical placebo, but it’s hard not to grudgingly admire just how—shall we say?—malleable or adaptable a placebo it is. What I mean by this is that, if you believe its practitioners and adherents, acupuncture can treat almost literally any disease or health problem. Any! Pain? Acupuncture. Allergies? Acupuncture. Biliary colic? Acupuncture. Infertility?…

Readers of this blog of a certain age and above are likely to remember a U.S. Senator from Wisconsin named William Proxmire. Sen. Proxmire made a name for himself in the late 1970s and throughout much of the 1980s by issuing what he dubbed “The Golden Fleece Award,” which was meant to “honor” public officials…

The approval of new drugs and medical devices is a process fraught with scientific, political, and ethical landmines. Inherent in any such process is an unavoidable conflict between rigorous science and safety on the one side, which tend to slow the process down by requiring large randomized clinical trials that can take years, versus forces…

I learned over the weekend that a historic figure in science-based medicine has died. If you know anything about the history of the Food and Drug Administration (FDA), you will know this woman’s name, Frances O. Kelsey, MD, PhD. It turns out that Dr. Kelsey died on Friday at the age of 101. Somehow I…

The conspiracy deepens. What conspiracy? You ask. Haven’t you heard? Big pharma is out killing alternative medicine doctors! Or at least that’s what you’ll be told if you venture towards the deep dark underbelly of quack websites. Up until now, the most prominent “victim” was autism quack, Jeff Bradstreet, who, according to police, committed suicide…

Mammography is a topic that, as a breast surgeon, I can’t get away from. It’s a useful tool that those of us who treat breast cancer patients have used for over 30 years to detect breast cancer in asymptomatic women and thus (or so we hope) decrease their risk of dying of breast cancer through…

A homeopathic “debate” in BMJ?

Homeopathy is quackery. There, I’ve said it for the hundredth or even thousandth time, but I don’t care if it’s repetitive because it can’t be emphasized enough times that homeopathy is The One Quackery To Rule Them All, with the possible exception of reiki and other “energy therapies.” I also find it useful to make…

One of my favorite quotes from classic literature comes from Lewis Carroll’s Through the Looking Glass, when Alice encounters a rather strange character named Humpty Dumpty. Humpty Dumpty, as you will likely recall, was a giant egg with whom Alice got into an argument about the meaning of words: And only ONE for birthday presents,…

The overarching goal that proponents of so-called “complementary and alternative medicine” (CAM) or, as is becoming the preferred term, “integrative” medicine is the mainstreaming of the “unconventional” treatments that fall under the rubric of these two terms. Indeed, that’s the very reason why they so insisted on the shift from calling it CAM to calling…

My opinion about medical marijuana has been fairly consistent. First, the claims made by its advocates for it far exceed the evidence for its benefit, which is why I’ve referred to it as the “new herbalism.” Of course, it’s not really very new, but it is herbalism in that medical marijuana advocates make grandiose claims…

When I wrote yesterday about the cruel sham that is “right-to-try,” , one criticism (among many) that I made of these misguided, profoundly patient-unfriendly laws was that I have as yet been unable to find a single example of a patient who has managed to obtain access to an experimental therapeutic through such a law,…

Last year, I did several posts on what I consider to be a profoundly misguided and potentially harmful type of law known as “right-to-try.” Beginning about a year and a half ago, promoted by the libertarian think tank known as the Goldwater Institute, right-to-try laws began popping up in state legislatures. I wrote about how…
