Mrs. Teasdale: Your Excellency, I thought you’d left!
Chicolini: Oh no, I no leave.
Mrs. Teasdale: But I saw you with my own eyes!
Chicolini: Well, who you gonna believe, me or your own eyes?
Duck Soup. Funniest movie ever.
If I could choose a super power, it would be neither flight nor invisibility, but the ability, like Triad, to separate into multiple people so I could accomplish more. I find that my multiple personality disorder is not all that efficient at getting things done. The Goth cowgirl? Lazy.
So sometimes I have to cut corners. As this post goes live I am at TAM helping with panel discussions and workshops and the only way I can get a post up is to cannibalize my lecture. Dr. Gorski will not let me post the slides and be done with it; those managing editors can be so unreasonable. Full sentences. Proper spelling. Good grammar. Sheesh. Some people.
The topic of my presentation is the cognitive errors that lead people to believe in nonsense and is, or was, a brief tour of the flawed ways in which we think and how the brain allows everyone to be under the false impression that fictions are real. (more…)
There needs to be a SCAM index, some quantitative tool, a formula for ranking the SCAMs, so one SCAM could reign supreme, to be definitely declared the the goofiest of all SCAMs. Perhaps (number of adherents)x(number of Pubmed publications)x(age of SCAM) all divided by a plausibility factor.
Homeopathy would win and any SCAM index that did not rank homeopathy at number one would have to put up a very convincing argument indeed that their formula was not somehow fundamentally flawed.1
For first time readers, homeopathy is based on several fictions, totally divorced from reality, made up in the 1800’s.
The first law,2 with less reality than Joe Abercrombie’s, is, “similia similibus curentur,” or “let like be cured by like”. Substances which cause specific symptoms can be used to cure diseases which cause the same symptoms. If like cures like, I am uncertain what moonlight, one of many fanciful homeopathic nostrums, would cure. Lycanthropy? (more…)
Most of what I read professionally is directed towards reality-based medicine. I spend my professional energies thinking about the application of reality to killing various and sundry microscopic pathogens.
The conceptual framework I use, and that used by others in medicine, does not concern itself with the application of the Supplements, Complementary and Alternative Medicines that occupy the attention of this blog. In acute care medicine SCAMs are of virtually no importance yet the approaches we need to take with patients and medicine are, with slight changes in emphasis, as applicable to SCAMs as real medicine. You need to remember, however, that the topic is not necessarily based in known reality.
Two viewpoints in JAMA caught my attention this month, both more thoughtful and reasoned than I am probably capable of. While focused on the application of reality-based medical practice, they apply to the topics of SBM as well. (more…)
Lest anyone think I am a heartless bastard, I would like it to be known that I do not like to see any creature suffer or die. I am the kind of person who, when finding a spider in the house, is likely to catch it and toss it outside. I always think, “I can’t squish the end result of 6 billion years of evolution”. Except mosquitoes. Those I squish with glee. Infection vectors can die die die die.
I like animals and hate to see them suffer unnecessarily. Like sticking them with needles. Frontal lobes are nice to have. They can let you know that pain is coming and provide preparation and compensation. Once I had a steel bar smack me on the head, opening up a six-inch cut to the bone. No, my brain was not affected, thank you very much. Everything predates the head trauma. When the ER doc numbed the scalp for sutures, he missed the last half-inch and I felt the needle. Knowing what was going on I steeled myself and let him do the last two sutures with no lidocaine, since the needle hurt only a little worse than the lidocaine injection. I have had many other unpleasant medical procedures in my 56 years but knowing what was coming and understanding why makes it easier to tolerate a needle popping into the knee joint or an abdominal drain being pulled.
Animals, and young humans, lack the ability to comprehend the what and why of pain inflicted as part of medicine. Adults can make a conscious decision to be endure pain and fool themselves into thinking it is of benefit. No pain, no gain. Animals can make no such choice.
For example consider sea turtles, who, apparently, are subjected to all sorts of nonsense at the New England Aquarium including acupuncture and laser therapy. As is obvious, I am no veterinarian, the only animal of which I have any understanding of anatomy and physiology is a human, but even with that background it is remarkable what is reported from New England. I used to say the ‘B’ students went into journalism; given the credulous reporting perhaps the standards have been lowered. They certainly have for marine biologists and veterinarians, who are evidently shortchanged in their education. (more…)
There is no satisfaction in hanging a man who does not object to it.
~ George Bernard Shaw
I work in a 5-hospital system and many of us practice at several hospitals. The residents rotate through at least three of the hospitals and the peripatetic nature of health care allows word of curious cases to percolate through the system. My current resident mentioned that there was a case of a vertebral artery dissection in a young female shortly after chiropractic neck manipulation.
Man, that’s awful. Is she doing OK?
Evidently there were no permanent neurologic sequelae. She dodged that bullet. Or perhaps that noose, as I once calculated that the force of a neck crack is about 40% that of hanging by the neck and it has the same pathologic changes if it goes wrong. Every time I see a death in the movie where the neck is twisted to break it, I think chiropractic, although some tolerate it better than others.
I have not written on CNS events related to chiropractic since 2008, although the topic has been covered by Dr. Hall. I still suspect that occasionally there is a perfect storm of bad luck, the forces are perfectly aligned in a susceptible patient and they get an embolic stroke or a vertebral artery tear.
Animal-assisted therapy is a huge topic: almost 1500 hits using those terms alone. There is no way I am going to cover all of them and do them justice. Instead I am going to cherry pick, er, I mean, select references of interest to illustrate issues surrounding animals in the hospital. Sometimes I get the impression that readers of the blog expect encyclopedic knowledge and understanding of a topic whenever we put pixel to screen. That is only true of the other contributors to the blog, not me.
I would like to mention that I do, in fact, like animals, even dogs. I loathe most dog owners, as confirmation bias suggests there is no such thing as a considerate dog owner. But I never have contact with the dogs that don’t bark, that don’t crap on my yard, that don’t run up to me to nip at my legs. I only see the dogs that their owners allow to behave in ways I would never allow a human to behave.
It is no surprise that my kids have grown up mostly animal free. My eldest did wear me down and I bought him a hamster. It promptly bit me, drawing blood. Great, I thought, LCM. Just what I need. Then in the dead of winter it escaped, fell down a heating duct (we were putting in new floor) and electrocuted itself on the heating coils so every time the heat turned on we smelled rotting, roasting hamster. It cost $500 to take the furnace apart and clean it. Good thing it wasn’t a beagle. That was enough pets in the house for me. (more…)
Infectious diseases (ID), as those who read my not-so-secret other blog know, is without a doubt the most interesting speciality of medicine. Every interesting disease is infectious in etiology. What is cool about ID is that it has connections into almost every facet of human culture and history.
I note that at some point I have gone from being the young whippersnapper to the Grandpa Simpson at my hospitals and am one of the few who has been around long enough to be a repository of institutional memory. I remember what it was like 20 plus years ago, when no one consistently washed their hands, when all S. aureus (S. aureui?) were sensitive to beta-lactams and we wore an onion on our belt, as was the style of the day. Oh the changes I have seen.
Besides remembering the not so good old days of my professional career, ID keeps me reminded of how the world used to be in the past. Medicine used to be about the epidemics that would routinely sweep across the world. Polio, measles, mumps, scarlet fever, rheumatic fever, tuberculosis and on and on. I occasionally see TB but thanks to modern medicine many of these scourges have mostly faded from medical practice in the US. Not a one, I might add, has faded due to the efforts of alt med practitioners.
Influenza still gives me pause. It is, as infections go, quite the tricky virus and it remains a difficult beast to treat and prevent. Which is a drag as it remains one of the more consistent causes of infectious morbidity and mortality. (more…)
Vacation then taxes have consumed my focus the last two weeks, and I have had little time to devote to issues of infectious diseases, much less SBM, so I will instead meander around a more philosophical terrain. I feel guilty when I do not have a substantive, data driven post evaluating a paper or essay in detail, but some weeks there just is not the time.
Being involved with SBM has been, like all intellectual endeavors, a process rather than result. I keep experimenting with conceptual frameworks with which I can understand the differences between a SBM approach and a SCAM (supplements, complementary and alternative medicine) approach. Nothing clarifies thoughts quite like writing them down. Or maybe not.
The motto of the blog is “exploring the relationships between science and medicine” but it is often more about non-overlapping boundaries* than relationships. We are often separated more by Berlin walls than Venn diagrams.
There are perhaps four boundaries that separate science-based medicine from those who prefer SCAMs. More if you are a splitter; I am a lumper by nature. At work I am an Occam kind of guy. (more…)
Medicine is impossible. Really. The amount of information that flows out the interwebs is amazing and the time to absorb it is comparatively tiny.
If you work, sleep and have a family, once those responsibilities are complete there is remarkably little time to keep up with the primary literature. I have made two of my hobbies (blogging and podcasting) dovetail with my professional need to keep up to date, but most health care providers lack the DSM-4 diagnoses to consistently keep up.
So we all rely on short cuts. People rely on me to put new infectious disease information into context and there are those I rely upon to help me understand information both in my specialty and in fields that are unrelated to ID.
Up and down the medical hierarchies we trust that others are doing their best to understand the too numerous to count aspects of medicine that no single person could ever comprehend.
If I want to know about the state of the art on the treatment of atypical mycobacterium or how best to treat Waldenströms or who knows the most about diagnosing sarcoid, there is always someone who can distill their expertise on a topic to the benefit of the patient and my knowledge.
Trusting others is the biggest shortcut we routinely take in medicine to wade through the Brogdignagian amounts of information that flood into medical practice. We have to trust other clinicians, the researchers and the journals that all the information is gathered and interpreted honestly and accurately. (more…)
You need to keep an open mind.
A common suggestion offered to naysayers of nonsense.
The usual retort concerns not letting one’s brain fall out.
Evaluating SCAM’s is less about having an open mind and more about having standards, a conceptual framework that is used to interpret and analyze new information. One of the benefits of writing and reading topics covered by science-based medicine (SBM) is it has clarified and sharpened the ideas by which I understand the world. Those concepts were nicely summed up by Steve Novella at Neurologica, and I reproduce them here, slightly modified. They should be on stone tablets, not quite commandants, but strong suggestions. The 8 strong suggestions somehow doesn’t cut it however. (more…)
