Orac is the nom de blog of a humble surgeon/scientist who has an ego just big enough to delude himself that someone, somewhere might actually give a rodent's posterior about his copious verbal meanderings, but just barely small enough to admit to himself that few probably will. That surgeon is otherwise known as David Gorski. That Orac has chosen his nom de blog based on a rather cranky and arrogant computer shaped like a clear box of blinking lights that he originally encountered when he became a fan of a 30 year old British SF television show whose special effects were renowned for their BBC/Doctor Who-style low budget look, but whose stories nonetheless resulted in some of the best, most innovative science fiction ever televised, should tell you nearly all that you need to know about Orac. (That, and the length of the preceding sentence.)

DISCLAIMER:: The various written meanderings here are the opinions of Orac and Orac alone, written on his own time. They should never be construed as representing the opinions of any other person or entity, especially Orac's cancer center, department of surgery, medical school, or university. Also note that Orac is nonpartisan; he is more than willing to criticize the statements of anyone, regardless of of political leanings, if that anyone advocates pseudoscience or quackery. Finally, medical commentary is not to be construed in any way as medical advice.

There’s always been a major thread of distrust of the medical profession in the African-American community, understandably so given the history of abuses such as the Tuskegee Syphilis Experiment, in which the natural progression of untreated syphilis was studied in African-American men for 40 years. It’s not just that experiment that’s responsible, either. During the…

Sigh. Here we go again. Robert De Niro is letting his antivaccine freak flag fly again, this time even higher than usual, by revealing that in the wake of the antivaccine debacle at his Tribeca Film Festival he is going to make his very own documentary about vaccines. It’s the continuation of a process that,…

Over the years, I’ve taken care of women with locally advanced breast cancer so advanced that it’s eroded through the skin, forming huge, nasty ulcers filled with stinky dead cancer tissue that’s outgrown its blood supply, leaving the patient in chronic pain. If the patient is fortunate, her cancer has not metastasized beyond her axillary…

it was less than a year ago that I described a bill wending its way through Congress called the 21st Century Cures Act “old vinegary wine in a new bottle.” The reason I characterized the bill that way was because it really was nothing new and it rested on a very old fallacy, namely that…

After yesterday’s epic mid-week rant about a man who thinks he knows what skepticism is but clearly doesn’t, it’s time to get back to business. The best way to do that is to go back to an article that came out the other day and that I had meant to blog about but temporarily shelved…

Contrary to what some of my detractors think, I don’t mind criticism of my viewpoints. After all, if I never encounter criticism, how will I ever improve? On the other hand, there are forms of criticism that are what I would call less than constructive. One form this sort of criticism takes is obsessive repetition…

So-called “alternative” medicine is made up of a hodge-podge of health care practices and treatments based on beliefs that are unscientific, pre-scientific, and pseudoscientific. These modalities include practices as diverse as homeopathy, traditional Chinese medicine, reflexology, reiki and other forms of “energy medicine” based on vitalism, chiropractic, and naturopathy, and that’s a short list of…

It is an unquestioned belief among believers in alternative medicine and even just among many people who do not trust conventional medicine that conventional medicine kills. Not only does exaggerating the number of people who die due to medical complications or errors fit in with the world view of people like Mike Adams and Joe…

It’s been a while since I paid attention to the movie, but the publicity among the antivaccine movement for Andrew Wakefield’s and Del Bigtree’s movie VAXXED: From Cover-Up to Catastrophe continues apace. Sadly, I missed my opportunity to see Bigtree himself doing a Q&A for the movie when it rolled through Detroit a a week…

I’ve written a lot about the language issue with respect to alternative medicine. As I like to put it (at least in shortened form), first there was quackery. Quacks did not like that name at all, and thus was born alternative medicine. And the quacks did think it good—for a while. There was a problem,…

One of the central messages that apologists for the use of alternative medicine and, particularly the integration of the unscientific and mystical treatment modalities of alternative medicine with real medicine—a phenomenon known as “complementary and alternative medicine” (CAM) or, more recently, “integrative medicine”—is that it’s popular. Oh. So. Popular. If you believe the promoters of…

It’s no secret that I’m a big fan of John Oliver. When my aging body allows me to stay awake late enough on Sunday nights and there’s a new episode on, I’ll almost always be watching. Since starting his own show Last Week Tonight With John Oliver on HBO, Oliver’s become quite the expert at…

I realize that it’s a cliché to say so, but some clichés are true. Time really does fly. It’s hard to believe that a year ago California—and, by proxy, the rest of the country—was in the throes of a major political war over the bill SB 277. SB 277, you will recall, was a bill…

Many are the cancer quacks—and just plain quacks—whom I have discussed over the years. Some of them, like Robert O. Young, have been truly horrendous, so bad that I’m left shaking my head and wondering how anyone can fall for their obvious misinformation and outright lies. For instance, Robert O Young claims that all cancer—not…

As regular readers of this blog and related blogs know, over the last two or three decades there has been a successful effort to legitimize quackery in the form of what is now called “integrative medicine.” Three decades ago, modalities like homeopathy, acupuncture, much of traditional Chinese medicine, reflexology, chiropractic, and many other modalities based…

[Note: Since this was written, Donald Trump won Indiana and Ted Cruz has suspended his campaign. This is why I changed the title of this post on Tuesday night. Meet your presumptive nominee, Republicans.] I haven’t written anything about Donald Trump and vaccines in a while. When last I did write about him, I enumerated…

If there’s one lesson that I like to emphasize while laying down my near-daily dose of Insolence, both Respectful and not-so-Respectful, it’s that practicing medicine and surgery is complicated. Part of the reason that it’s complicated is that for many diseases our understanding is incomplete, meaning that physicians have to apply existing science to their…

Three days ago, I noted a disturbance in the antivaccine Force. Last night, I noticed that that disturbance continues. The first time around, it was Brian Hooker, a biochemical engineer turned incompetent antivaccine “epidemiologist” completed the circle of clueless conspiracy mongering, who was at the center of the disturbance. His conspira-woo tapped into the Dark…

I hate these stories, because they so seldom end well. Unfortunately, this one is more messy than even the usual messiness of the typical story of this type. The type of story I’m referring to, of course, is one that I’ve told from time to time ever since near the first year of this blog’s…

About a month and a half ago, I became aware of the case of Ezekiel Stephan, a 19-month-old Canadian toddler living in Alberta who in 2012 developed bacterial meningitis. Unfortunately for Ezekiel, his parents, David and Collet Stephan, were believers in alternative medicine. They didn’t take Ezekiel to a real doctor. Instead, they relied on…

There is a disturbance in the antivaccine Force. I can sense it. Actually, it doesn’t take any special talent to detect this. You don’t have to be some sort of pro-science Jedi. The evidence is everywhere. The most prominent examples of posts in the antivaccine crankosphere that tipped me off are on—of course!—the antivaccine propaganda…

Arguably, one of the most popular forms of so-called “complementary and alternative medicine” (CAM) being “integrated” with real medicine by those who label their specialty “integrative medicine” is acupuncture. It’s particularly popular in academic medical centers as a subject of what I like to refer to as “quackademic medicine“; that is, the study of pseudoscience…

I heard the news yesterday morning. I was in clinic seeing patients. It was a bit of a slow morning; there was time between patients. So I spent it, as is my wont when clinic is a bit slow, signing charts (OK, signing off on charts in the electronic medical record; I haven’t actually physically…

Now that I’ve dispensed with Mike Adams’ attacks (for now), It’s time to get back to business as usual. No way am I going to let Adams interfere with the business of this blog for more than one day to take note of it, even though he’s now gone basically batshit crazy. Unfortunately, no sooner…

Several of you have noticed that a certain friend of the blog has been under attack from one of the quackiest of Internet quacks out there. Here is his response. The paranoia and stupidity are black hole level density. (Yes, instead of posting the whole thing, I’ve simply posted a link to our friend’s discussion…
