Point-of-Care Ultrasound: The Best Thing Since Stethoscopes?

A bit of good news for a change: a “Perspective” article in the New England Journal of Medicine describes how point-of-care ultrasound devices are being integrated into medical education. The wonders of modern medical technology are akin to science fiction. We don’t yet have a tricorder like “Bones” McCoy uses on Star Trek, but we are heading in that direction, and the new handheld ultrasound devices are a promising development.

The stethoscope has become iconic, a symbol of medical expertise draped proudly around the neck by doctors and other medical personnel. Before it was invented, doctors could only try to listen to a patient’s heart by direct application of ear to chest. In 1816, Laennec interposed a tube of rolled paper between ear and chest, and the stethoscope was born. It quickly became an essential tool, allowing us to hear the distinctive murmurs produced by different heart valve abnormalities, to take blood pressures, to detect the wheezing of asthma or the collapse of a lung , to hear the bruits caused by atherosclerotic narrowing of blood vessels, to detect intestinal obstructions by listening for borborygmi (I love that onomatopoeic word!).

The stethoscope allows us to hear sounds produced by the body, but sound also allows us to see inside the body. Diagnostic ultrasound has a multitude of uses. With prenatal sonograms, we can determine the sex of a fetus, watch it suck its thumb, and even take its picture for the family album. With echocardiography we can evaluate heart valves, see fluid accumulation in the pericardium, observe the thickness and motion of the heart wall, and even quantify the efficiency of the pumping process. Ultrasound lets us see clots in blood vessels and stones in the gallbladder, evaluate abdominal organs, detect cysts, screen for carotid artery narrowing and abdominal aortic aneurysms, and guide needles into the body for therapeutic and diagnostic purposes.

Stanislaw Burzynski’s propaganda victory on antineoplastons: The FDA caves

Mark Crislip, founder of the Society for Science-Based Medicine, whose board of directors I’m proud to be serving on, an organization that you should join if you haven’t already, sometimes jokes that our logo should be an image of Sisyphus, the king of Ephyra whom Zeus punished by compelling him to roll an immense boulder up a hill. However, the boulder was enchanted and, as soon as Sisyphus reached the top, it would roll back down the hill. Sisyphus was thus forced to repeat this action throughout all eternity. The metaphor is obvious. Those of us who try to combat quackery and the infiltration of pseudoscience in medicine often feel a lot like Sisyphus. I always used to argue that, as amusing as it might be to have such a logo as an “in” joke, it’s far too much of a downer to inspire what SSBM wants to inspire: Action in the form of volunteers taking on projects, such as converting Quackwatch into a wiki and then continuously updating and adding to that wiki indefinitely. We have to believe that there is hope of someday succeeding. “Let’s push that boulder up a hill one more time!” does not exactly constitute an inspiring rally cry, although I can definitely understand the feeling at times the older I get and the longer I’ve been doing this. We can all appreciate gallows humor at times, and, besides, I’m not that pessimistic. I can’t afford to be.

Even so, I can understand the Sisyphus analogy right now with respect to an unfortunately frequent subject of this blog, the doctor in Houston who proclaims himself a cancer doctor, even though he has no formal training in medical oncology, isn’t even board-certified in internal medicine, the prerequisite for undertaking advanced training in medical oncology, and has no discernable training in clinical trials management. I’m referring, of course, to Stanislaw Burzynski, MD, PhD, the Polish doctor who since 1977 has been treating patients with substances that he has dubbed “antineoplastons” (ANPs). What are ANPs? Burzynski claimed to have discovered ANPs during his time at Baylor and described them as endogenous cancer-fighting chemicals in human blood and urine. Unfortunately, he soon became convinced that only he could develop them into an effective chemotherapy drug and left Baylor to administer ANPs to his own cancer patients. Patients flocked to him because he claimed to be able to cure cancers that conventional medicine can’t cure.

This led to a series of battles between Burzynski and various authorities, including the Texas Medical Board, the FDA, and various attorneys general, because of his use of ANPs, which are not and never have been FDA approved, as well as for various—shall we say?—issues with insurance companies. Ultimately, in the 1990s Burzynski beat the rap and effectively neutered the FDA’s case against him by submitting dozens of clinical trials to the FDA for approval, which, given how much pressure the FDA was under from Burzynski’s friends in high places (like Texas Representative Joe Barton), the FDA ended up approving. However, as Burzynski’s lawyer himself bragged, these clinical trials were shams designed to allow Burzynski to keep treating cancer patients, not clinical trials designed to produce any real evidence of efficacy. Not surprisingly, although Burzynski has published the odd case report or tiny case series, he has not yet published the full results of even a single one of his many phase II trials. There is, quite simply, no convincing evidence that ANPs have significant antitumor activity in vivo in humans, even after 37 years. Meanwhile, the FDA has found numerous examples of Burzynski’s abuse of clinical trials, failure to keep necessary data, and failure to protect human subjects, while exposés by BBC Panorama and Liz Szabo at USA TODAY have been most unflattering, revealing at least one dead child as a result of the toxicity of Burzynski’s drug and a pattern of minimizing and hiding reports of adverse reactions.

Agnotology: The Study of Ignorance

A comment from the blog:

Every single time – bar none – I have had a conversation with someone about CAM and its modalities, they are absolutely astonished when I explain to them what the modality really is. One story I love telling comes from my friend in the year behind me. His parents are professional chemists and he came home one day and saw his mother had a bottle of homeopathic medicine. He asked why and she gave the typical non-committal response of “well, I thought it may help and I saw it on the shelf at the pharmacy.” He explained what homeopathy actually is and they were absolutely dumbfounded. They are well aware of Avogadro’s number, after all. People generally don’t study what the CAM in question actually is – merely the fluff PR garbage that gets touted around and without direct and clear demonstration of harm, give it a pass as a result. After all, the business of real medicine is time consuming and difficult enough.

Participating in activities that have a permanent record gives one the fortunate, or unfortunate, opportunity to revisit the past and see just how you worked early in a career. (more…)

Naturopathy vs. Science: Allergy Edition

snakeoil

I glanced at my pharmacy license recently, and noticed I became a licensed pharmacist almost exactly twenty years ago. Two decades seems like a long time to do pretty much anything, yet I can still vividly recall some of the patients I encountered early in my career, working evenings in a retail pharmacy that drew heavily on the alternative medicine crowd. It was the first pharmacy I’d ever seen that sold products like homeopathy, detox kits, salt lamps, ear candles, and magnetic foot pads. And the customers were just as unorthodox. There were some that told me they manipulated their own pH, and others that insisted any prescription drug was designed to kill. And there was a huge clientele that relied on the pharmacy for their “bioidentical” hormones. It was an instructive learning experience, as it was as far from the science of pharmacy school as you could expect to find in a place that still called itself a pharmacy. One of the really interesting aspects of that pharmacy was the enormous supply of vitamins and supplements for sale. It stretched over multiple aisles and even back into where the drugs were kept, as there were some brands kept behind the counter. This wasn’t for any regulatory reason – it was because these were the “naturopathic” supply, the brands often recommended by naturopaths. In order for this pharmacy to sell them they had to keep the products behind the counter, presumably to grant these supplements a veneer of medical legitimacy. After all, they were “special”, and had the prices to prove it. (more…)

Medical Conspiracies

Anyone publicly writing about issues of science and medicine from a pro-science perspective likely gets many e-mails similar to the ones I see every week. Here’s just one recent example:

Im sorry the medical community has become decadent and lazy as most that follow your stance could care less to study the real truth. I have also seen it much more deviant as many professionals know the risks and harm vaccination cause but continue to push it through there practices because of pure greed. Many are also scared of loosing there practices for not following the corrupt industry. Im sorry but the medical industry has become drug pushing decadent slobs that only care about there bottom line.

The e-mailer clearly has a particular narrative that he is following (in addition to the amusingly common poor grammar and spelling). He even writes at one point in our exchange, “the details really don’t matter at this point what matters is what the bigger picture…” He is certain of his big picture conspiracy narrative. The details are unimportant.

Nature vs. Technology

For those who dismiss advocates of the “natural” as ignorant of science and deluded by the logical fallacy that natural = best, Nathanael Johnson’s new book is an eye-opener: All Natural: A Skeptic’s Quest to Discover if the Natural Approach to Diet, Childbirth, Healing, and the Environment Really Keeps Us Healthier and Happier. If nothing else, it is a testament to the ability of the human mind to overcome childhood indoctrination in a belief system, to think independently, and to embrace science and reason.

Nathanael Johnson was brought up by hippie parents who subscribed to every “natural” belief and fad. His mother nearly died of a postpartum hemorrhage when he was born at home (he weighed 11 pounds!). His parents didn’t report his birth, and he didn’t have a birth certificate. He co-slept with his parents, never wore diapers (imagine the clean-up!), was allowed to play in the dirt and chew on the snails he found there, was fed a Paleolithic diet, was never allowed any form of sugar, didn’t know there was such a thing as an Oreo cookie, was home-schooled, and did not know that public nudity was taboo until he and his brother shocked the folks at a church picnic by stripping naked to go swimming in the lake. Nudity was customary in his home, and he was encouraged to “let his balls breathe.”

As he grew up, he started to question some of the dogmas he had learned from his parents. He had been taught that good health resulted from forming connections with nature, but he found that nature “generally wanted to eat me.” Now an adult and a journalist, he understands science and how to do research. He tried to read the scientific literature with an unbiased mindset, asking questions about the subjects in his book’s title rather than looking for evidence to support any prior beliefs, and he arrived at pretty much the same conclusions we science-based medicine folks did. But he still appreciates that a natural approach has value, and he seeks to reconcile nature with technology. He calls his book a comfortable refuge from people who are driven to extremes. (more…)

A bit of shameless self-promotion: Dr. Gorski interviewed by Point of Inquiry about Stanislaw Burzynski

Every so often, I or one of my fellow SBM bloggers, is interviewed somewhere. This time, it’s my turn, and this time I was interviewed by Lindsay Beyerstein over at Point of Inquiry. In these days when credulous reporters still, in essence, do Burzynski’s bidding with respect to the message he wants to get out, while Burzynski takes advantage of the desperation of patients with incurable cancers, every little bit helps to counter that message.

Hopefully that’s what I’ve done. Please check out the interview.

A tale of quackademic medicine at the University of Arizona Cancer Center

Quackademic medicine.

I love that term, because it succinctly describes the infiltration of pseudoscientific medicine into medical academia. As I’ve said many times, I wish I had been the one to coin the phrase, but I wasn’t. To the best of my ability to determine, I first picked it up from Dr. R. W. Donnell back in 2008 and haven’t been able to find an earlier use of the term. As much as I try to give credit where credit is due, I have, however, appropriated the term “quackademic medicine” (not to mention its variants, like “quackademia”), used it, and tried my best to popularize it among supporters of science-based medicine. Indeed, one of my earliest posts on this blog was about how quackery has infiltrated the hallowed halls of medical academia, complete with links to medical schools that have “integrative medicine” programs and even medical schools that promoted the purely magic-based medical modalities known as reiki and homeopathy. It’s been a recurrent topic on this blog ever since, leading to a number posts on the unethical clinical trials of treatments with zero or minimal pre-trial plausibility, the degradation of the scientific basis of medicine, and the acceptance of magical thinking as a means of treating patients in all too many medical centers.

One strong candidate for quackademic ground zero, if there can be such a thing for the phenomenon like quackademic medicine, which is creeping up like so much kudzu in the cracks of the edifice of science-based medicine (SBM), is the University of Arizona. U. of A. is, of course, the home of one of the originators of the concept of quackademic medicine and one of its most famous and tireless promoters, Dr. Andrew Weil. Dr. Weil, as you might recall, has even been the driving force for creating a highly dubious “board certification” in integrative medicine. Sadly, apparently this new board certification has been so popular among physicians wanting to “integrate” a little quackery into their practices, that its first examination has been delayed from May to November 2014, so that the American Board of Physician Specialties can figure out how to accommodate the unexpectedly large number of applicants.

So what happens when a patient arrives at U. of A. for treatment? I found out last week when I received an e-mail, which led to a fairly long e-mail exchange, with a man whose son was diagnosed with leukemia and is being treated at the University of Arizona Cancer Center (UACC). Although this man gave me permission to use his name, I am going to decline to do so because there is a child involved, although anyone involved in his case at U. of A. will likely quickly be able to identify who the man is. It turns out that he is a professor at U. of A. in a humanities department (which is why I’ll refer to him henceforth as the Professor), and, even though he is not a scientist, he clearly knows how to think (which would not be surprising if you knew what department he was in). In his e-mail, he told me how appalled he was at the sorts of treatments being offered to his son:

Nightmares, Night Terrors and Potential Implications for Pediatric Mental Health…..

Earlier this month, the typical media outlets were abuzz (“Childhood nightmares may point to looming health issues“) with the results of a newly published study linking early childhood nightmares and night terrors with future psychotic experiences. Expressing little in the way of skepticism, most reports simply regurgitated the University of Warwick press release. The research, published in the quite legitimate journal Sleep, is interesting but I’m not sure it tell us anything that we don’t already know. And it certainly doesn’t support any causal relationship between sleep disorders of any variety and “delusions, hallucinations, and thought interference”. But before we delve into the specifics of the paper, I believe a quick review of sleep, and sleep problems, in children is in order.

What is sleep?

To the outside observer, sleep appears as an altered level of consciousness where response to our environment and voluntary movements are noticeably decreased. But, with a certain degree of variability, the line between sleep and wakefulness is pretty thin. This distinguishes it from the increasing stimulation required to reverse other states of altered consciousness such as lethargy, obtundation, stupor and ultimately coma, which is not acutely reversible. I don’t plan on getting too technical, but there is obviously much more to sleep than that. Physiologically our metabolic demands drop a bit, and we enter a generalized anabolic or “growth” state during which a number of beneficial processes take place, predominantly, we think, involving the brain.

Sleep is a vital aspect of human life that has appears to have both physiological and psychological purpose, and is essentially universal in the animal kingdom. All you need to do is observe a cat for more than five minutes to see that we aren’t the only animal species that both needs and seemingly enjoys sleep. In fact, if you could talk to a nematode, it would likely go on for hours about how much it enjoys sleeping in on Sundays. Humans spend roughly a third of their lives asleep, but the percentage of each day devoted to sleep is significantly higher during infancy and early childhood.

We don’t know why the need to sleep became part of the blueprint for life so early on in our evolutionary history, and researchers certainly haven’t worked out all of the nuances of why humans and other animal species continue to be so dependent on it throughout the lifespan. It is likely that its purpose has broadened over time as species branched out into new environments. There are a number of leading hypotheses, however. And barring some amazing technological or medical advance, we appear to be stuck with sleep.

When healing turns into killing: religious and philosophical exemptions from parental accountability

Parents have a fundamental right to guide the upbringing of their children protected under the Due Process Clause of the U.S. Constitution. This includes the choice of medical care for the child. They also have a First Amendment right to the free exercise of their religious beliefs, including the right to care for their children in accordance with the tenets of their religion. In a better world, these rights would be exercised in a manner that is consistent with a reasoned selection of medical care among choices supported by the best available scientific evidence. If, for example, deeply religious parents choose to forego a treatment that had only a minimal chance of extending their child’s life and terrible side effects in favor of palliative care because they believe that their child would be better off in heaven we could all agree that their choice is constitutionally protected.

Unfortunately, that is not the case. Religious believers and those whose “philosophy” favors pseudoscience in child medical care (surveys bloviating about the popularity of CAM to the contrary) are in fact a tiny minority of the American population who influence public policy in a manner that far exceeds their actual numbers. This influence allows these special interest groups to cause needless suffering and death among children and their families. As well, their actions siphon off medical and legal resources that could more properly be directed toward the common good when states and medical institutions are put in the position of having to go to court to protect children from their parents. And, by giving parents false choices between a belief in magic and standard medical care, unnecessary complications are introduced into what are already difficult and heart-wrenching decisions by parents who truly want to act in the best interests of their children.
