“Battlefield acupuncture”?

THE SCENE: Iraq, Afghanistan, or anywhere where U.S. troops are risking life and limb.

THE TIME: The not-too-distant-future. Maybe even 2009.

Joe is on patrol.

It’s the middle of summer in the desert town. The air hangs heavy, hot, dry and dusty, like a blast furnace firing steel. The heat penetrates Joe’s 80 lb pack in much the same way the heat from boiling water penetrates the shell of an unfortunate lobster. Joe’s heart races. His squad is on edge; their eyes dart furiously to and fro, looking for the deadly threat that might lurk in the shadows. Every shadow is a potential source of death, every alley a refuge from which the enemy can attack and kill him or his buddies, every rooftop a fortress from which the enemy can rain death upon the squad. The area is known to be thick with terrorists and insurgents. Joe pictured them waiting unseen from every nook and cranny for the opportunity to attack. The skin on Joe’s back is all prickly. He distinctly feels as though he has a huge bullseye pointed on his back. He feels a bead of sweat dripping down his forehead and onto his eyelid, all slimy and salty. Joe desperately wants to wipe it away, but that would necessitate removing one of his hands from his weapon. The split second it would take for him to put it back might mean the difference between life and death for him or one of his buddies.

A loud roar fills Joe’s ears, and suddenly he feels as though he has no weight. The scene unfolds in slow motion, just like in the movies. Dazed, Joe hears a tumult as though from a great distance, but can see nothing. Yelling and gunfire all around, he becomes conscious enough to realize that he’s lying flat on his back. He feels searing pain in his legs and a hot liquid oozing around them. It occurs to Joe that it must be his own blood or even perhaps his own urine, but he’s just too dazed to care.

“Medic!” Joe hears someone scream. He feels someone pull his helmet from his head and realizes that the sound of gunfire and yelling is receding. His unit must be driving away the ambushers. Good! He thinks. Give those assholes hell, guys! He opens his eyes, and realizes that his buddy’s got his back, and turns to see another man, a medic, drop to his knees at his side. His uniform is stained a disturbing red. Joe feels the medic wrapping something around his thigh. It’s a tourniquet, and Joe cries out in pain as he feels it constricting around his upper thigh.

“Bleeding’s better!” Joe hears the medic say to his buddy. “I’ll take it from here.” Joe’s buddy runs off to join the rest of his unit, and the medic moves his face close to Joe’s. He feels himself being moved from side to side and then his legs being moved. More pain. Joe cries out.

The medic leans in to talk to Joe, “I think we’ve got the bleeding under control for now. I put a tourniquet on your leg. Let’s get you out of here. The docs’ll patch you up in no time.” Joe is vaguely aware of another corpsmen with a stretcher nearby. The medic leans in again, “Are you in pain, soldier?”

“What do you think? My leg hurts like a sonofabitch! I could really use something for the pain,” Joe hears himself yelling, again as if from a distance. Pain is shooting through his leg, setting every nerve on fire, and the tourniquet is biting into raw muscle through the edge of a wound that comes all the way up to his groin. The flayed edges of his skin shoot fire to his brain, and he can feel his broken bones grinding against each other every time he moves in spite of the splint.

“I’ve got something better that’ll help,” the medic screams over the din.

Better? Joe thinks. I’m in agony here. I need something! Anything!

The medic pulls a small box out of his pack. Joe sees that it’s a small case. He opens it. Its contents look something like this:

Joe is puzzled. Where’s the morphine? He wonders. “What are those needles?” Joe asks. “What are you doing? I’ve never seen syringes that look like that before!”

“Acupuncture,” replies the medic. “I’ll take care of you.”

“What are you going to do with them?” Joe replies.

“Stick them into your earlobe. It’ll take the pain away really fast.”

“Are you shittin’ me?” Joe screeches, trying to get up to grab the medic by the front of his uniform. “My leg’s a bloody mess, I’m in agony, and you’re tellin’ me you’re gonna stick little needles in my ear and make it all better? Like that‘s going to do anything! I need real pain medicine! Give me morphine! NOW!

Biofeedback and Laser for Allergies

AllergiCare Relief Centers are a chain of franchises started by a man called David Tucker who is not listed as having an MD or any other title. They offer diagnosis of allergies by biofeedback and treatment of allergies by laser acupuncture. They admit that the method is not backed by any science, and they claim that what they are doing is not medical treatment.

Responsible journalism might have investigated this as quackery or practicing medicine without a license. Instead, irresponsible journalism has helped promote these centers and has given them invaluable free advertising.

From one news story:

Tucker said the device works based on biofeedback. The allergy sufferer wears a sensing clip on his finger for testing, and the computer simulates the bio-frequency for 10,000 known allergens. As the body responds to those stimuli, the computer lists which substances are irritants. “This digitized allergen actually matches the harmonic frequency of the actual allergen, making the body believe it is in contact with the real substance,” Tucker said. “The body will react if it is allergic to the particular substance.” ….Once the allergens are identified, a laser stimulates biomeridian points on the body — the same points used in acupuncture and acupressure. Tucker said the idea is to strengthen organs to act properly the next time they encounter the allergen — that is, to treat them as harmless…So far, there is no science to prove the devices work, but Tucker claims a 70 percent positive response rate.

“It’s just a theory”

I am afraid that the experiments you quote, M. Pasteur, will turn against you. The world into which you wish to take us is really too fantastic.

La Presse, 1860

It’s just a theory. Not evolution. Germ theory. Just a theory, one of many that account for the etiology of diseases.

I should mention my bias up front. I am, as some of you are aware, an Infectious Disease doctor. My job is simple: me find germ, me kill germ, me go home. I think there are three causes of disease: wear and tear, genetic, and germs. Perhaps a bit of an exaggeration, but not much. My professional life for the last 22 years has been spent preventing, diagnosing, and treating the multitudinous germs that a continually trying to kill or injure us. It is a fundamentally futile job, as in the end I will be consumed by the organisms I have spend a lifetime trying to kill.

I would have though that the germ theory of disease was a concept that was so grounded in history, science and reality that there would be little opposition to the idea that germs (a broad term for viruses, bacteremia, fungi, parasite etc) cause infections and some other diseases.

Wrong. There are people who deny the validity of germ theory. Add there are people who deny gravity. And evolution.

Opponents of germ theory come in two flavors:

  1. Germ theory deniers.
  2. Those who propose alternative mechanisms of disease.

There is great overlap between the two categories, and the division serves more as a literary device for the sake of exposition than a true description of reality.

Puncturing the Acupuncture Myth

Note: This is slightly revised from an article I originally wrote as a “SkepDoc” column for Skeptic magazine. It was pre-released online in eSkeptic and it has already generated a lot of comments, including “a truly amazing piece of peurile pseudo-intellectualism,” “an ad hominem attack on one form of alternative medicine so beset by poor thinking that one must come to the conclusion this woman might just be paid to write such propaganda,” and “twaddle wrapped in swaddling rhetoric.” (I treasure comments like those as evidence that my critics are so bankrupt of real arguments that they have to dip into the insult pouch for ammunition.)  I thought it would be interesting to post it here on the blog and see how much controversy it would stir up among my co-bloggers and readers.  Please keep in mind that it was written for a popular audience and excuse the lack of scholarly citations. You may recognize some of the studies I refer to from previous blog entries.

———

“Alternative” medicine is by definition medicine that has not been scientifically proven and has not been accepted into mainstream scientific medicine. The question I keep hearing is, “But what about acupuncture? It’s been proven to work, it’s supported by lots of good research, more and more doctors are using it, and insurance companies even pay for it.”

It’s time the acupuncture myth was punctured – preferably with an acupuncture needle. Almost everything you’ve heard about acupuncture is wrong. (more…)

Trick or Treatment

I’ve just finished reading Trick or Treatment: The Undeniable Facts about Alternative Medicine by Simon Singh and Edzard Ernst. I’d been looking forward to the publication of this book, and it exceeded my expectations.

Edzard Ernst, based at the University of Exeter in England, is the world’s first professor of complementary medicine, a post he has held for 15 years. An MD and a PhD, he also embraced alternative medicine and used to practice homeopathy. He has done extensive research and published widely. His stated objective is “to apply the principles of evidence-based medicine to the field of complementary medicine such that those treatments which demonstrably do generate more good than harm become part of conventional medicine and those which fail to meet this criterion become obsolete.” His most important accomplishment has been to “demonstrate that complementary medicine can be scientifically investigated which, in turn, brought about a change in attitude both in the way the medical establishment looks upon complementary medicine and in the way complementary medicine looks upon scientific investigation.”

Simon Singh is a science writer with a PhD in particle physics. As a team, he and Ernst are uniquely qualified to ferret out the truth about alternative medicine and explain it to the public. (more…)

Sterile Water Injections for Pain Relief

Before ethical standards changed, doctors used to occasionally fool patients with placebo injections of sterile saline or water. If my obstetrician had tried to give me sterile water instead of an epidural, I probably would have hit him. But apparently women are getting sterile water injections for childbirth and are telling us they work. What’s going on?

A recent study in Sweden compared sterile water injections to acupuncture for relief of labor pain. It found that sterile water produced significantly greater pain relief and relaxation. It concluded, “Women given sterile water injection experience less labor pain compared to women given acupuncture.”

I’m puzzled, because the study also says “there were no significant differences regarding requirements for additional pain relief after treatment between the 2 groups.” 85% and 90% got nitrous oxide, 40% and 47% got epidurals, and other conventional interventions were also used. It seems to me the conclusion could just as well have been “Women given sterile water injections report less labor pain than women given acupuncture, but require just as much additional pain relief.” (more…)

Another Acupuncture Study – On Heartburn

Blogging on Peer-Reviewed ResearchPatients with heartburn are often diagnosed with GERD (gastroesophageal reflux disease) and treated with a drug called a proton pump inhibitor (PPI) to reduce stomach acid production. It is pretty effective, but it doesn’t always work. When it doesn’t, standard practice has been to double the dose of PPI. Doubling the dose only improves symptoms in 20-25%. Most patients who fail the single dose turn out to have normal esophageal acid exposure, or “functional” heartburn. In other words, the symptoms appear to be due to something other than excess acid – so it really may not make much sense to double the PPI dose. What else could doctors try?

How about acupuncture? A recent clinical trial compared acupuncture to doubling the proton pump inhibitor dose in refractory heartburn. (more…)

Snake Oil Science

For my first blog entry, I wanted to write about something important, and I couldn’t think of anything more important than a recent book by R. Barker Bausell: Snake Oil Science: The Truth About Complementary and Alternative Medicine. If you want to understand how medical research works, if you want to know what can lead patients and scientists to false conclusions, if you have ever used complementary or alternative medicine or have wondered why others do, if you value evidence over belief, if you care about the truth, you will find a treasure trove of information in this book.

Some of the treatments encompassed under “complementary and alternative medicine” (CAM) have been around for a long time. Before we had science, “CAM” was medicine. Back then, all we had to rely on was testimonials and beliefs. And even today, for most people who believe CAM works, belief is enough. But at some level, the public has now recognized that science matters and people are looking for evidence to support those beliefs. Advocates claim that recent research validates CAM therapies. Does it really? Does the evidence show that any CAM therapy actually works better than placebos? R. Barker Bausell asks that question, does a compellingly thorough investigation, and comes up with a resounding “NO” for an answer.

Bausell is the ideal person to ask such a question. He is a research methodologist: he designs and analyzes research studies for a living. Not only that: he was intimately involved with acupuncture research for the National Center for Complementary and Alternative Medicine (NCCAM). So when he talks about what can go wrong in research and why much of the research on CAM is suspect, he is well worth listening to.
