AK: Nonsense on Full Automatic

I start these entries about a week before their due date, and when I saw Dr Hall’s Applied Kinesiology (AK) post from Tuesday, I thought the heck, there goes my post for Friday.  After reading Harriet’s post, I think mine will be both complementary and alternative, and perhaps even integrative, to her entry.  I do have one quibble with her post. She said

“we skeptics don’t dismiss AK just because it sounds silly.”

AK doesn’t just sound silly, it is silly.  I have found over the years writing for SBM that I have developed an increasing bias around the concept of prior probability.  As best I can tell there is a well described reality, and that reality constrains what is not only probable, but what is possible.  Within the limitations of our current understanding of reality, some processes are impossible, i.e. have zero prior probability. AK’s prior probability is exactly zero.   I sometimes think the blog should be called Reality Based Medicine.  Science gives us understanding of reality and AK, like many a SCAM (Supplements, Complementary and Alternative Medicine) discussed in this blog, parted company with reality from the beginning.

This blog has two often overlapping purposes.  Blogs offer timely commentary on contemporary issues, and this blog certainly fills that role.  More than other blogs, SBM also has the opportunity to be a reference source on various SCAM’s .  I have had the recent opportunity to reread the entire oeuvre of SBM, and it is impressive in the breadth and depth of topics covered in its three plus years.  It is not yet encyclopedic and there are many topics not yet reviewed in the blog, such as Applied Kinesiology.  So many many SCAM’s, so little time.

Placebo Again.

Medicine is simultaneously both easy and hard. As an Infectious Disease doctor, my day can be summed up with the phrase “me find bug, me kill bug, me go home.” Sometimes it is just that simple. A lot of the time it isn’t. I may not be certain what the infection is, or even if the patient has an infection, or allergies and/or antibiotic resistance limit therapeutic options, the host has co-morbidities that limit effectiveness, and the patient has no financial resources for the needed treatment.

I am lucky, since most infections are acute, make people feel terrible, and require a relatively short course of therapy during which the patient feels better. I rarely have to worry about compliance with the treatment plan; it is the rare patient, usually a heroin user or a particularly irascible old man, who will not follow through with their antibiotic course. I do not have to worry about chronic or symptomless diseases like diabetes or hypertension or the complications of obesity where long term compliance often limit therapeutic success. Long term it is difficult for many people to stick with their therapeutic plan, much less their diet and exercise resolutions.

Alas poor Craniosacral. A SCAM of infinite jest, of most excellent fancy.

It is hard to Sokalize alternative medicine. The closest has been buttock reflexology/acupuncture, but that is a tame example.  Given the propensity for projections of the human body to appear on the iris, hand, foot, tongue, and ear, postulating a similar pattern on the buttocks are simple variations on a common SCAM (Supplements, Complementary and Alternative Medicine) theme. The buttocks?  Not really different from any of the other focal acupunctures.  Most of SCAM does not concern itself with application of reality  and physiology, anatomy, biochemistry, etc can all be expected to be ignored with virtually all SCAM modalities.

Every time I think the heights (or depths) of absurdity has been reached, I discover a Braco the Starer or Himalayan Salt Inhalers. This blog is not affiliated with the British Medical Journal in any way, and although this is being published near Christmas, I want no one think that what follows is a hoax.  I am not, I repeat not,  making up what follows. It is not fiction. Well, it is fiction, but not written by me and believed and practiced by some who really should know better.

A Seal of Approval

I have never belonged to the American Medical Association.  As a student I didn’t want to pay the dues. As a practicing physician I am of the opinion that the AMA has two often mutually exclusive goals (promoting physician income and patient care)  and they are doing both badly.

In the 1990’s the AMA entered into a contract with Sunbeam to get an AMA seal of approval for Sunbeam products, but due to objections the AMA backed out of the deal, in the end costing them almost 10 million dollars.

As was noted at the time:

“I think if we’d gone to trial,” Dr. Relman said on Saturday, ”probably a lot more relevant information would have been uncovered and made available to the membership. As a result of this settlement, we will never know the truth of what happened. It does not let the sun shine in.”

Yeah AMA. It is probably for good reason that only  around 29% f of US physicians belong to the AMA; I have never seen them as representing me or my patients.  Whether the AMA or physicians, I am automatically suspicious of any person or institution who puts their seal of approval on a product.  I figure they are only doing it for the money.  Not that there is anything wrong for that; I am for sale if anyone can meet my price.  Trusting endorsements is like George Carlin’s (I think) observation that he did not like doing standup for stoners since you never know if was the act or the dope that lead to the laughter. I know celebrities are paid for their endorsements; it is not conflict of interest when it is your job to sell a product. At least actors say they only play a doctor on TV.  But when professionals use their authority to recommend products, I would love to see a conflict of interest statement in the recommendation.

When I give a lecture I have to mention my conflicts of interest (COI)* and I have to specifically confirm or deny that I will mention products in which I have a financial interest^. The COI rules are nice, so you know, sort of, who has an interest in pleasing their corporate masters, although I suspect most doctors do not take COI statements seriously.  At IDSA this year most of the speakers gave their COI statements with a short, dismissive sneer and a roll of the eyes.  Me?  Potentially Biased? Puh-please. (more…)

November Hodgepodge

There have not been a lot of topics of late that warrant extensive analysis and discussion.  But there are a number of little topics of interest, each worthy of a few paragraphs of discussion, archetypes of issues in medicine, science based and otherwise.

Xigirs. No, it is not whale vomit, but close.

Last month Xigris  was pulled from the market by Lilly.  Yes, I understand the shock. Xigris, we hardly knew ye.   Xigris is the brand name for drotrecogin alfa, or activated protein C.  It is an enzyme in the clotting cascade that is/was given for the treatment of sepsis. (more…)

Random Flu Thoughts

I normally write the first draft of this blog the weekend before it is due, and this is no exception.  However, I am ill this weekend.  Headache, myalgias., painful cough, but only mildly ill.  The worst part is the interferon induced brain fog; my thoughts flow with all the speed of pudding and I was not appreciably better as the week progressed, although no cracks about how  you can’t any difference in my writing over baseline.

I doubt the cause of my symptoms is influenza.  According to the CDC site and Google flu trends there is little influenza activity in the US at the moment, so it is probably one of the innumerable viruses that can cause a flu-like illness.  I am also not ill enough to think I have influenza, but I could be having a modified course as I was vaccinated a month ago.  Of course, the doctor who treats herself has a fool for a patient and an idiot for a doctor. Flu season approaches, so from my interferon addled brains, flu thoughts.

Alternative Vaccination Schedules

Evidently the 7 billionth human is going to be born on October 31. Happy birthday and welcome to the Earth.  If you were unfortunate enough to be born into a developing country or a affluent California family, you may not receive your vaccinations, and may join one the 57 million who die each year of vaccine preventable diseases (VPD).

I totally misread the table.  It’s about 4,320,000 who die of VPD. Well, I said I was no damn good at stats.

And if you are doubly unlucky, you may be exposed to illness from an unvaccinated friend, family or health care worker before you can get your vaccines, and join the ranks of the ‘only’s.’  The ‘only’s’ are those who die of vaccine preventable diseases and are mentioned in anti-vaccine literature in a sentence like ‘VPD X is a mild illness in most children and only kills Y% of cases ’.  As I have said before the anti-vaxers do not care for whom the bell tolls.

I am no good at statistics.  I signed up for, and dropped, statistics at least 4 times in college.  Once they got past the bell shaped curve, it was one incomprehensible huh?  Part of the problem with statistical concepts such as risks, both relative and absolute, is that it is often impossible to get a feel from what they represent. For me it is like metric measurements.  I know what a 8 mile hike represents, but not an 8 kilometer hike.  Same with centigrade and liters.  I have been unable to internalize what metric means in my daily life.

The Prostrate Placebo

I seem to be writing a lot about the urinary tract this month. Just coincidence, I assure you. As I slide into old age, medical issues that were once only of cursory interest for a young whippersnapper have increasing potential to be directly applicable to grumpy old geezers. Like benign prostatic hypertrophy (BPH). I am heading into an age where I may have to start paying attention to my prostate (not prostrate, as it is so often pronounced, although an infection of the former certainly can make you the latter), so articles that in former days I would have ignored, I read. JAMA this month has what should be the nail in the coffin of saw palmetto, demonstrating that the herb has no efficacy in the treatment of symptoms of BPH: Effect of increasing doses of saw palmetto extract on lower urinary tract symptoms: a randomized trial.

It demonstrated that compared to placebo, saw palmetto did nothing. There have been multiple studies in the past with the more or less the usual arc of clinical studies of CAM products: better designed trials showing decreasing efficacy, until excellent studies show no effect. There is the usual meta analysis or two, where all the suboptimal studies are lumped together, the authors bemoan the quality of the data, and proceed to draw conclusions from the garbage anyway. GIGO.

The NEJM study from 2006 demonstrated that saw palmetto was no better than placebo but it was suggested that perhaps the dose of saw palmetto was not high enough or that the patients were not treated long enough to demonstrate an effect, and the JAMA study hoped to remedy that defect. (more…)

Recycle

Like most people who grew up after April 22, 1970, I think it is important to be as environmentally responsible as possible.  Like many I fail miserably much of the time, but at least I feel guilty about it.  Recycling offers the opportunity to feel good about my environmental impact with little effort, since the garbage collection infrastructure in Portland makes recycling easy.

Some products are best extensively reprocessed before reused. Urine, as an example. There are proponents of topical and/or drinking urine as a treatment/cure for nearly any illnesses.  The kidneys are mostly responsible for fluid and electrolyte balance and I realize that normal urine is mostly water, salts, urea and a smattering of other very dilute molecules. I have the urine tox screen to prove it.  Urine is not a particularly noxious body fluid, but it is not high on my list of liquids to drink under normal circumstances.

Urine is mostly water but not an optimal source of water if it is your only source for fluids.  Urine drinkers love to mention the occasional trapped earthquake victim who survives, in part, from drinking their own urine.  For the first several days the urine would be dilute enough to keep people reasonably hydrated, as humans cannot concentrate urine as well as, say, a camel.  So I can see where consuming urine for a short period of time would delay progressive dehydration and death. A couple days of drinking urine neat, shaken not stirred, would be harmless and, if there were no alternative sources of water, beneficial. I do suffer from the societal taboo that piss is icky, and for aesthetic reasons urine is not something I would want to consume, even when it is referred to as its more common designation ‘Coors Light’.

Gullible George

I get the occasional email.  Very little hate mail, unfortunately, since hate mail is often more amusing.  I read what little email I receive, and usually do not respond, mostly as I do not have the time.  I am a slow writer and a slower typist, and there are just so many hours in the day, and the older you get, the shorter th0se hours become.

Recently, over at the center of the growing Mark Crislip multimedia empire, I had the following in the feedback section:

Just thought you’d like to know:

My kids watch the PBS show “Curious George” which usually does a good job with introductory Physics, Astronomy, scientific method, etc. Interspersed with the cartoons they have scenes with real children that do a real-life parallel investigation of what happened on Curious George.

Today’s episode involved the Man with the Yellow Hat catching a cold, and Curious George going to the pharmacy and picking up various drugs to assist in making the guy feel better, mainly to have him sleep and be comfortable.

The interspersed skit, however, had the children visit a naturopath, where they learned:
* Oregano cures infections
* Various pressure points that correspond to energy lines
* And that taping magnets to these points is really effective.

I sat here simply amazed.

Me, not so much.  Alternative medicine has always been a blind spot for PBS.  While PBS  would not show perpetual motion machines,  suggest that astrology is legitimate, or give credence to a flat earth, alternative medicine, as it is for many otherwise thoughtful people, is exempt from even cursory critical thinking. PBS has broadcast  Drs. Chopra and North, so its track record with science based medicine is not so good. My children are long past the Curious George part of their lives, but I read them the books when they were kids.  Not my favorite (I like the Madeleine books better; 6 weeks in hospital for an acute appendix never failed to amuse me) but they were a quick read when the kids wanted a story at bedtime and I was too tired for a longer exposition.
