A new study sheds more light on the question of what is causing the recent increase in the rate of diagnosis of autism. Professor Dorothy Bishop from the University of Oxford studied adults who were diagnosed in 1980 with a developmental language disorder. She asked the question – if these people were subjected to current diagnostic criteria for autism, how many of them would be diagnosed today as having autism? She found that 25% of them would. (Bishop 2008)
This epidemiological question has been at the center of a controversy over whether or not there is a link between vaccines (or the mercury-based preservative, thimerosal, that was previously in routine childhood vaccines) and autism. The primary evidence for this claim put forward by proponents of a link is that the number of diagnoses of autism increased dramatically at the same time that the number of vaccines routinely given to children was increasing in the 1990’s. They are calling this rise in autism an “epidemic” and argue that such an increase requires an environmental factor, which they believe is linked to vaccines.
That the number of new autism diagnoses is dramatically increasing is generally accepted and not a point of debate. The historical rate of autism is about 4 per 10,000 and the more recent estimates are in the range of 15-20 per 10,000 (30-60 per 10,000 for all pervasive developmental disorders of which autism is one type). (Rutter 2005) The controversy is about what is causing this rise in diagnoses. There are two basic hypotheses: 1) That the true incidence of autism is rising due to an environmental cause, 2) That the rise in incidence is mostly or completely an artifact of increased surveillance and broadening of the definition of autism. These two hypotheses make specific predictions, and there is much evidence to bring to bear on their predictions – this recent study only being the latest.
Charlatan: America’s Most Dangerous Huckster, the Man Who Pursued Him, and the Age of Flimflam, by Pope Brock, is not only a rip-roaring good read, but it brings up serious issues about regulation of medical practice and prosecution of quackery. It tells the story of John R. Brinkley MD, who transplanted goat glands into people, and of Morris Fishbein MD, the editor of the Journal of the American Medical Association, who tried to stop him.
Brinkley was a colorful character whose very first job was a scam, selling a patent remedy. He went to medical school but never finished, eventually buying a diploma elsewhere for $100. A bigamist, drunkard, liar, and con man of incredible audacity, he built up an empire of quackery that made him filthy rich. Apart from his medical adventures, he practically invented modern political campaigning techniques, revolutionized advertising, and was almost single-handedly responsible for popularizing country music and the blues with his radio station.
An impotent patient supposedly told Brinkley, “Too bad I don’t have goat nuts.” So Brinkley gave him some. A few weeks later he went back for a refresher course in surgery (which he failed because of drunkenness and poor attendance). He began to feel that he was gifted and should not be bound by the “jealous sheep ethics” of the AMA. (more…)
I have to apologize for last week’s post. I’m not apologizing for the subject matter (the obsession that reigns supreme among some alt-med aficionados over “cleansing” their colons to “purge toxins” and achieve the super-regularity of several bowel movements a day). Rather, I’m sorry I probably didn’t emphasize quite strongly enough just how disgusting one of the links that I included was. Among all the glowing testimonials found there touting how lovers of that “clean feeling” inside felt after having supposedly rid themselves of all that nasty fecal matter caked on the walls of their colons and achieved the Nirvana of many bowel movements a day (or, as one happy customer put it, “awesome adventures in the bathroom” and another put it, “I have not noticed anything really weird come out of me yet, but I am sure that there will be”), there were also links to various pictures people took of their own poop, complete with graphic descriptions. A couple of years ago when I showed an acquaintance of mine the Dr. Natura website shortly after I had discovered it, he declared it the “grossest thing on the web.” Sadly, I had to assure him that it was not–not by a longshot. However, I will try spare you any links to anything significantly grosser, preferring instead to leave finding them as an exercise for interested readers.
After having apologized for perhaps grossing out some of our readers, who come to this site for science- and evidence-based discussions of various so-called “complementary and alternative medicine” therapies, not pictures of the various excretions of the human body proudly lined up by the humans who produced them, I thought about what might be a suitable followup this week to such a topic. There really is only one followup that’s appropriate to this stuff, believe it or not. The problem with which I wrestled is that it really is pretty much as disgusting as last week’s topic, if not more so. (You’ll soon see why.) So there I was, trapped on the horns of a dilemma. Hesitating only momentarily, though, as any good general surgeon would do (remember, before I specialized in breast cancer surgery I was a general surgeon, as prone to dive into big brown on the loose as any other general surgeon), I decided just to dive in to the topic as I would have in the old days dived into a particularly foul belly full of purulence, particularly since this week’s “CAM” modality of choice claims to be able to take away a big chunk of the “bread and butter” practice of general surgery by curing a common surgical disease without all that nasty cutting, even if these days it’s almost always done laparoscopically.
So, are you ready for liver flushes? Of course you are. Don’t you want a way to “remove gallstones without surgery“?
Of course you do.
A Reminder (Mainly to Myself): this Blog will Eventually get back to Discussing the NIH Trial of the “Gonzalez Regimen” for Treating Cancer of the Pancreas†
Which, if you’ll recall, is an arduous dietary and “detox” regimen that includes 150 pills per day, many of which contain pancreatic enzymes, two “coffee enemas” per day, “a complete liver flush and a clean sweep and purge on a rotating basis each month during the 5 days of rest,” and more. In Part II I ventured off on a tangent about Laetrile and government sponsorship of trials of implausible cancer “cures.” That became more involved than I had planned (but also more enlightening, or so I hope), and Part III continues on that tangent.
The Politics of “Alternative Cancer Treatments”: the Lamentable Legacy of Laetrile (cont.)
The whole tide is beginning to turn toward metabolic therapy for degenerative disease and preventive medicine. Laetrile…has been the battering ram that is dragging right along with it…B-15,…acupuncture, kinesiology, …homeopathy and chiropractic…And we’ve done it all by making Laetrile a political issue.”
-Michael Culbert, editor of The Choice, the newsletter of the Committee for Freedom of Choice in Medicine. Quoted in 1979.¹
In January I had the pleasure of attending TAM 5.5 in Fort Lauderdale. On the last day of the conference the JREF had an open house where anyone interested could come see the inner workings at the JREF facility. Since I had a rental car I decided to go through the lobby to see if anyone needed a ride, and sure enough one Dr. Harriet Hall took me up on my offer.During the 20 minute drive that I had Harriet captive we were able to have a pleasant and illuminating (for me) conversation, during which I told Dr. Hall about an experience I had with a chiropractor in my neck of the woods. This got me thinking about honesty and purposeful deception in alternative medicine, and for this reason I’m going to start this blog entry off with a personal anecdote about an incident that occurred some years back just after I graduated from Nursing and had become a full-fledged registered nurse.
After having some back problems I decided to go to a respected chiropractor in Calgary (a city of about 1 million people). Since it was my first visit I needed to go through a full ‘assessment’ and the chiropractor took my blood pressure, had me step on two scales (one for each foot) so that he could weigh both sides of my body simultaneously, and he also took a single anterior X-Ray of my chest/spine (anterior means an X-Ray taken straight on with my back against the photographic plate – actually I think the technical term for that is an AP or anterior-postero X-Ray).
Measuring placebo effects (often misleadingly referred to as the placebo effect – singular) is a part of standard clinical trial design, because they need to be distinguished from the physiological effects of the treatment under study. Rarely, however, are placebo effects the actual target being measured, but such is the case with a new study published in the most recent edition of the British Medical Journal (BMJ) – Components of placebo effect: randomised controlled trial in patients with irritable bowel syndrome. (Here is a summary if you cannot access the article directly.)
Dr. Ted Kaptchuk et.al. studied the response to various placebo treatments in 262 adults with irritable bowel syndrome (IBS). The three groups were designed to address three major categories of placebo effects: 1) response to the process of being assessed and observed, 2) response to being given a placebo treatment, and 3) response to the patient-practitioner relationship. These types of placebo effects were represented by three treatment arms: 1) observation alone, 2) placebo acupuncture, 3) placebo acupuncture plus an “augmented” practitioner-patient relationship – with added “warmth, attention, and confidence.”
Phrenology was a 19th century pseudoscience that claimed to associate brain areas with specific personality traits. It was based on palpating bumps on the skull and was totally bogus. New brain imaging procedures are giving us real insights into brain function in health and disease. They are still blunt instruments, and it is easy and tempting to over-interpret what we are seeing. In his book The New Phrenology William Uttal warns that “the excitement of these new research tools can lead to a neuroreductionist wild goose chase” and that we must be careful not to succumb to new versions of the old phrenology.
The Amen Clinics, founded by Daniel G. Amen, MD, offer SPECT (single photon emission computed tomography) scans to help diagnose and manage conditions such as attention deficit disorders (ADD), mood disorders, anxiety and panic disorders, autistic spectrum disorders, obsessive compulsive disorder (OCD), substance abuse, toxic exposure, brain trauma, memory problems, temper problems, and relationship and marital struggles.
The scans generate colored pictures of the brain that show “areas of your brain that work well, areas that work too hard, and areas that do not work enough.” They do not actually provide a diagnosis, but “must be placed in the context of a person’s life, including their personal history and mental state.” “The goal of treatment is to balance brain function, such as calm the overactive areas and enhance the underactive ones.” (more…)
“Death begins in the colon.“
Perhaps you’ve heard this little bit of “alternative medicine” wisdom. Oddly enough, I had never heard it until well after I had become a surgeon (although my first thought upon hearing it was that it would make a killer name for a rock band or a blog). That’s when I began encountering claims that seemed to indicate that constipation was the most evil thing in the world, something that must be avoided at all costs. Naturally, I wondered just what the heck was meant by this bit of “wisdom.” What, I wondered, was it based on? What, I wondered, was the purpose of it? To answer this question, recently I decided to go back and review what people say about colon health:
Have you ever considered this simple question: Are you clean inside?
Last Week’s Entry: Everyone’s a Winner!
The resounding total of 4 “translations” for the second W^5 entry might have been trying to tell me something…nah!
I gotta say that each of the four nailed the central point: the esteemed Institute of Medicine (IOM), a subset of the esteemed National Academy of Sciences, has decided that it’s just fine—no, it is “important” and even “required”—that when it comes to “CAM,” the medical profession dispense with ethics, law, and science. Otherwise we might mistakenly argue, er, against the “integration of CAM therapies with conventional medicine.” That, clearly, would be unacceptable.
Stephen Barrett and others have critiqued some of remainder of the text. Regarding our own group of translators: yeah, you are all winners, but Stu once again rose above the crowd. Whadizzy, some kinda ringer? If he keeps this up I might have to insist that he be tested for performance-enhancing substances.
Hoodathunk that the IOM’s opinions are for sale? They are: the language that you deconstructed was bought and paid for, as we clunky Americans are so fond of saying, by…you and me! Yup, our tax dollars, funneled through the NCCAM and some other government agencies, generated the very Pap that we Smeared.
This Week’s Entry
In order to encourage more participation, I’ll try limiting entries to a single paragraph each, for a while anyway. This week’s entry, which will be the first of several from the same treatise, is found on the website of the American Medical Student Association (AMSA) as part of its “CAM Education Initiative“:
EDCAM – CAM and Medical Education Report
Medicine today is experiencing a paradigm shift that involves the blending of two disparate philosophies of health and disease, the biomedical or scientific reductionist view and the clinical, experiential holistic view. While the biomedical model reduces disease to a disturbance in biochemical processes and relies heavily on the “curative model” of care, holistic medicine derives from a “healing model,” which emphasizes the complex interplay between multiple factors: biochemical, environmental, psychological, and spiritual.
Feel free not only to restate it in the Queen’s English (it’s already in the Prince’s), but to comment upon its assertions. Remember, you gotta week, and I’ll announce the lucky winners in 2 weeks.

Laetrile and the Politics of NIH-Sponsored trials of “Alternative Cancer Treatments”
Part I of this blog ended by asking how, in light of the implausible and arduous nature of the “Gonzalez regimen” for cancer of the pancreas, and the unconvincing “best case series,” the NIH could ever have decided to fund a trial of it.† This entry will begin to answer that question. In so doing it may seem to veer from the original subject, but hold on to your seats: what you’ll find here is a piece of the treasure map that leads to the Mother Lode of Fool’s Gold that is government-sponsored “CAM” research.
All historical accounts of the encroachment of implausible claims into the research agenda of the NIH must begin with Laetrile. By that is meant all implausible claims, not merely those having to do with cancer. Elsewhere we have traced the history of “chelation therapy” for coronary artery disease, and have shown that its origins as a political movement, eventually leading to an unethical, $30 million, 2000 subject NIH trial, were intimately associated with people and organizations advocating Laetrile—the most lucrative health fraud ever perpetrated in the United States. In that essay we offer evidence that the creation of the NCCAM itself was at least partly attributable to the history of Laetrile and its advocates. Several good histories or partial histories of the Laetrile debacle are available online, including here, here, here, here, here, and here. The best,¹ but one that does not seem to be available online, is by the recently deceased dean of historians of American quackery, James Harvey Young. (more…)
