I do not want to get all angsty and omphaloskeptic, but I have been thinking more of late about the purpose of the blog and my role in it. Blogs,and the people who write them, are ephemeral. It takes a unique personality and commitment to churn out these essays and commit them to the ether. Especially since Michelson and Morley.
I have never given much thought as to who our readers are, at least as a composite. I read most of the comments on every entry and have certainly developed a mental picture of some of our regular commenters, although I suspect I probably do not have even the gender correct most of the time. The commenters represent a tiny fraction of the regular readers and an even smaller fraction of occasional readers. It occurs to me I haven’t a clue who the real audience of this blog is.
I write first for my own education and entertainment, then for the slightly bored and overwhelmed medicine resident, since that is who I spend most of my time educating at work. Someone educated with an understanding of basic medicine but has more important things on their mind than a need for a detailed understanding of why homeopathy is complete nonsense. I doubt the majority of my readers are health care workers and I suspect continuing medical education is not a major part of the blog.
I never considered SBM to be a consumer protection group, but this week my wife showed me a half page advertisement in the local paper, and I realized that not only was the advertisement a good topic for blogging, but consumer protection is a fundamental result of this blog. There really is no site on the interweb that looks at both SCAM and real medicine with quite the same skeptical eye. Here is the headline:
A Special Wellness Report
New Medicine Based On An 88- Year Old Theory By Albert Einstein Can Help Almost Everyone Who Is Sick Or Injured! (more…)
It feels like I live in the real world example of Ray Bradbury’s All the Summer in a Day but for the last two weeks we have had sun and heat and it has been glorious. I get Christmas and Thanksgiving and New Years as vacation, but who needs that? I need July and August to live the vida loca in the Oregon summer. Who wants to blog when I can be outside, at concerts, golfing, hiking and…
Yes Dr. Gorski. I did agree to write an entry every other Friday. Yes Dr. Gorski. I know you have the documentation. Yes Dr. Gorski, I do not want any of that information made public. No one needs to know that I wanted to be a naturopath when I was young. Sigh. Yes, Sir, I will get to blogging. Damn those youthful indiscretions. Let’s see how little I can do and meet my obligations with the powers that be.
My professional career is based upon inflicting death, and in my time I have obliterated uncountable numbers of unicellular organisms. If there were such a thing as Karma, I would certainly return in the next life as a rabbit in a syphilis lab. But there isn’t, and I can kill and kill with a clean soul. There is no guilt or hesitation in killing unicellular life, or even multi-cellular life, as long as it cannot be seen without a microscope. I start to get a wee bit squeamish as soon as I can see a life form. I tend to not kill bugs or animals, unless, of course, they can be eaten. If it tastes good, all bets are off. But as a tree hugger, I tend to look upon killing wildlife and extinctions as a bad thing. (more…)
There is a tradition in medical training called Journal Club. The first rule of Journal Club is you do not talk about Journal Club. In Journal Club, at least in the iterations in which I have participated, one article is selected by an attending, everyone reads it, then the strengths, weakness and applicability are discussed by the group. Usually a top notch, ground breaking article was the focus, one that had high potential clinical impact. But since they were good articles in good journals, there was not a lot to learn about in reguards to critical thinking. While the attending would put the article in context and maybe discuss some rudimentary statistics, there was little that was discussed about the quality of the study. The main take home from every study was to question the applicability of the results to populations that were not old, white males, since it seemed all the ground breaking studies back in the day were a VA Cooperative study of one sort or another.
As I remember it, there was not really a conceptual frame work with which to evaluate studies. Bayes theorem, and its application to clinical medicine was never explicitly discussed outside of testing, where you have to consider the prior plausibility of the patient having a disease before you can decide if the test results is a true positive or not. In Portland, Oregon, the chance that a Lyme serology is a false positive is much greater than a test done in Portland, Maine. Generally speaking in the information overload state that is the practice of medicine, clinical trials are generally taken at face value and tests are considered infallible. Which is a shame, as I wonder how much suboptimal medicine is inflicted on patients by not considering prior plausibility and how accurate a given test is in either ruling in or out a disease. There seems to be a whole industry built around treating patients with no risks for Lyme but have positive tests of doubtful provenance. We never discussed the prior plausibility and its effect on the outcomes of a studied treatment. (more…)
Summer time is finally here in Oregon, and I will confess that I have spent little time on blogging. The sun is out, my kids are out of school and home from college, and really, who wants to spend their time writing when you could be on the golf course or at the beach with the kids. I say this as a mea culpa for what follows.
One of the saving graces in medicine is just how hard it is to harm people and how much trauma humans can withstand and survive. When I am on call for my partner I cover a Level 1 trauma ICU and the hallway leading to the unit is lined with photographs of some the trauma survivors. Over the years I have helped take care of many of these patients and I remember the extent of the injuries and the intensity of the care required to pull them through. Most of the survivors are young; it is the young who have the physiologic reserve to deal with the stress of injuries and their consequences.
Still, human physiology is amazingly resilient, especially of there are no co-morbid conditions to interfere with healing. With a little, and sometimes a lot, of support, I am constantly amazed at what people can sometimes survive. Modern medicine can pull people through who would have certainlu died 20 years ago.
There are two way to hurt people: what you do and what you do not do, the harms of commission and omission. Harm can be obvious with surgery. Oops, sorry I left my watch in there. I definitely do not have what it takes to be a surgeon. Or you can prescribe a medicine with a known side effect. Most SCAM’s, by doing nothing, are not prone to this sort of harm. Chiropractic and acupuncture are the notable exceptions, but even then it is hard to tear a vertebral artery or drop a lung unless the patient is extraordinarily unlucky. Of course one of the things you learn in medicine is that occasionally someone is extraordinarily unlucky and has a rare, but not unexpected, complication of an intervention, SCAM or otherwise.

As I have mentioned in the past, almost all of my practice is inpatient medicine, doing infectious disease consults in acute care hospitals. I only spend three hours a week in the outpatient clinic, so I have a skewed perception of medicine and disease. The patients I see are sick, really sick, often trying to die and are a complicated collection of abnormal labs and deranged physiology.
I remember finishing residency thinking that a potassium of 2.8, a hemoglobin of 9.8 or a bilirubin of 4.5 wasn’t all that bad, losing track of normal physiology amongst all the medical pathology. I never did lose track of normal vital signs (VS): pulse, respiration, blood pressure and temperature. Like trying to be the fifth Beatle, over the years other values have vied to become the fifth vital sign: pain level or O2 saturation, but none have the importance of the fab four. I can live without pain*, but I can’t live long if the other vital signs are abnormal for extended periods of time. Watching the vital signs return to normal is often an important variable that signifies the patient is improving. (more…)

I found Harriet’s post on the Medscape Connect topic of How do you feel about Evidence-Based Medicine? interesting.
I wondered about the breakdown of the comments by both specialty and opinions about SBM. So I read the 226 comments and classified them by field and response. I classified each response as disapprove, approve or nuanced. It is not, obviously, a legitimate survey and there was more than a little subjective interpretation in deciding how to classify the responses. I have no doubt that others would get different results; it is not methodologically sound analysis. The discussion was in the Family Medicine & Primary Care section, so it is unlikely to be representative of any population, including that of Family Practitioners and Primary Care Physicians. I would bet, as in alternative medicine and most topics, Shruggies predominate and are the silent majority.
Even though I belong to what a commentator referred to as the not so silent “militant wing” of SBM, I was surprised at my results: (more…)
There is no shortage of technology in my household: computers, smart phones and tablets of one kind or another. The nice thing about being a blogger and an app developer is I can justify it all. Well, mostly. The “It’s probably tax deductible” gambit can only be used so many times. It is remarkable how much of my life is filtered through the digital lens. I think if google glasses ever become a reality, my kids and I will be the first up to be permanently wired into the world. To my way of thinking, the Daemon haunted world looks like hog heaven.
There is an app for just about anything, many of which feed into my OCD. I keep track of my daily walk and I have walked over 1500 miles since July 1, 2011. When I developed my middle aged bloat I had the option of medications to control the metabolic results or lose some damn weight. Losing weight is simple in concept, hard in execution. Take in fewer calories than you expend and the weight will slowly, ever so maple bar free slowly, come off. It took 9 months to drop the 45 pounds needed, and I must say I feel just as old and creaky as I did before, but my labs are better. The opposite of the placebo effect: I am subjectively the same but am objectively better. I’ll take it. One of the cool features of the app I used, and still use, for calorie management is that it will take a picture of the bar code of food and give you the nutritional information for entry in the program. Amazing.
A fellow bugdoc sent me a link to story about Chinese Tongue diagnosis. The journal article has been accepted for publication as Automated Tongue Feature Extraction for ZHENG Classification in Traditional Chinese Medicine
It is as fine a piece of tooth fairy science and tooth fairy engineering as I have ever encountered. (more…)
For all the goofiness that is SCAM, I never thought I would have a post with Cannibalism in the title. The ability for humans to find imaginary healing properties in everything from duck liver and heart diluted 1:100 200 times, rhinoceroses horns, and waving hands over people to adjust energy fields that do not exist is remarkable. Somehow I never thought Jeffrey Dahmer would be at the forefront of alternative therapies.
Wednesday evening while my wife was reading me the paper (it is how I usually consume the local newspaper, my wife reads stories she finds of interest out loud. Otherwise I do not think I would bother with anything beyond the comics and sports page) she let it be known that Korean officials has confiscated medications containing aborted fetuses and stillborn babies. Instead of the usual distracted, uh huh, that’s interesting, this caught my attention. Say what?
I usually rely on the Secret. Every two weeks or so the Universe offers up some bit of wacky whimsey and I have a topic for an SBM blog entry. This week the Universe has failed me. Nothing has crossed my LCD so I have no studies to evaluate and I have been unusually busy at work preventing my browsing the Interwebs for material. But try telling that to the Managing Editor. I write half to amuse myself, half to learn about the topic, and half to clarify in my own mind the topics at hand (1). So this week is content free idle thoughts for my own benefit.
I have been reading 13 Things That Don’t Make Sense by Michael Brooks. The book concerns topics in science that are unexplained by the current understanding of the laws of the universe or contradict the dominant paradigm. Well, almost. His final topic is homeopathy, and it is the one topic whose conclusions, while qualified, belong on Failblog. The first chapter concerns dark matter and dark energy and how what we can see makes up only a small fraction of the content of the universe. (more…)
Although I write the definitive entries on topics in this blog, new information trickles in after publication. The new studies are often not worth an entire entry, recapitulating prior essays, but the new information is still worth a mention. What follows are updates on topics covered in prior SBM posts.
In Oregon we are having a small outbreak of infections from consumption of raw milk. Not a surprise, since milk is a wonderful culture media and the udder is just down the gravity well from the cows anus. Raw milk violates the classic dictum “Don’t shit where you eat” although I understand the saying concerned dating in its original conception.
Although the sale of raw milk is illegal in muchof the US, the law can be bypassed by owning the cow rather than buying the milk, a reverse of dating advice. Such is the case in Oregon, where 48 people are time sharing the cows responsible for the current outbreak. There has been the spread of pathogenic E. coli to at least 5 people, mostly children, and has lead to the hospitalization of at least 3 children.
Of course, it is hard to get infected. Humans have lived in Filth and Squalor (like Minneapolis and St. Paul or Buda and Pest) for centuries, drinking and eating contaminated food and enough survived perpetuate the species. Most infections in the past would have been from consuming contaminated food and drink. I have wondered if the reason fevers are often associated with diarrhea and/or vomiting is that it an evolved response for removing infected material as soon as possible.
