Maggie's FarmWe are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for. |

Wednesday, June 17. 2009What we learned this week in the charity clinic: Good deeds are often punishedNo good deed goes unpunished. Well, that is surely not always true, but with the economic downturn, the charity medical clinic at which I volunteer one day per week has seen a sharp upturn in lawsuits against us Docs and the clinic this year. The medical defence lawyer we have now engaged (we have had no complaints or suits for 10 years until January 2009) tells us that we should now regard each patient as a potential enemy. (Our clinic's founding Christian philosophy is to regard every patient as a friend and neighbor.) He tells us that our notes must be guided by the principle of CYA (your notes are legal documents, not medical reminders as we had thought) and that every decision a doc makes contains some basis for a suit in the hands of a hungry lawyer because all medical decisions are judgement calls and every situation is unique. He also told us that recessions tend to see more suits against doctors because more folks are looking for cash, and much more so in charity settings. Plus the tort lawyers are hungry too - but they always are. He also advised us to refuse to treat any patients with substance abuse histories for our protection - other than alcohol. He actually said "Do not be kind. They will screw you whenever they decide to." He has been around the block a few times. I do not like this at all. A Psychiatrist/Psychoanalyst cannot do the job under such conditions. Furthermore, I can not and will not endure any relationship in my life without mutual trust. I am considering resigning (even though I was one of the founders of the place) and finding some other outlet for my charity. Maybe prison work, where you can safely begin with the assumption that everybody is a liar and cheater and working the system - and take it from there. My position on the Board, plus my volunteer time (all unpaid) doubles my legal liability. I just want to do my best, tithe and double-tithe my time, and avoid hassles that do not fit into my life - and legal fees that I cannot comfortably afford. And no, I would never work for ObamaCare. Never. I did not go into medicine to be a government employee. I went into medicine to work for my patients, doing my best, with no intention of looking out for lawyers.

Tuesday, June 9. 2009People who may need but do not really want your helpIt's tough for doctors because we are often held responsible for people who either do not want, or do not accept, our help and advice. But, as long as their name remains on our rolls and as long as we persist in trying to be constructive, the lawyers can get us. I have been burned several times by keeping them on the rolls in the charity clinic, only to be sued by them eventually for not doing a better job "taking care of them." What? I am not a professional mother and I do not "take care of" anybody. I am a doctor, not a caretaker and, despite the modern lingo, not a "care-giver" either. Like all doctors, I try to work with my patients - and do not take care of them, or I to try to bring them around to where I can work with them. If I were more self-protective, I would not even try and would just say "I cannot help you. Good bye," but that is not my medical tradition. My medical tradition is that you are a friend to your patients, whoever they are. Novalis presents such a case. More practical docs than I am would just throw them out of the office. However, after being punished and hassled legally several times by going the extra mile, my heart grows harder. Indeed, good deeds often are punished and yes, it does lead to some bitterness especially when it is performed on a charity basis. I have never been sued or hassled by a private, self-paying patient.

Wednesday, May 27. 2009Orgasms after death, and other interesting topics
Via Tiger at Althouse, Mary Roach (author of Stiff) with video on orgasms from fetus to death.
Friday, May 8. 2009A Limp and a DeathAnother reminiscence from our shrink friend Nathan about his days in the Indian Health Service -
Before I could stop completely, John Running Horse lay one hand on the open window of my red Fiat 128, bowed in head and cast, asked, “You the new doc?” I was. “Put this thing on again”; hands me the cast, then points to his gondoliering leg. I park and head in. The Indian Health Service had told me that there were two docs; arrive Sunday. But, by Sunday, Dr. K. had been flown out with her atrial flutter to be cardioverted eighty miles up the road to Mobridge; Dr. L. was riding shotgun with a mother in active labor also to Mobridge. No docs in Eagle Butte. I wrapped a new cast on John Running Horse’s right leg and asked as I did so -- dipping plaster rolls in warm water, smoothing them first around, then smoothing downward along the fracture to make it seamless -- how his old cast got cut off. Itched, he said; cut it off himself, as he unsheathe his James Black/Musso pattern S-guard bowie knife. White plaster still dusted its curved Stainless steel back tip and brass quillion; hadn’t even wiped it clean. I told John Running Horse that his skin would itch again after a few days; dried skin flakes. I found a metal coat hanger, bent it straight and showed him how he could insert it within the cast to scratch itches. He found this marvelous; made a special leather sheath for it to hang from his belt. Later, he returned; brought a water color gift; painted himself on his horse; he wearing Sioux gear. In his right hand, born aloft like some victorious banner is not a leg cast, but his Winchester Model 1894 lever-repeating rifle -- the gun that won the West, the weapon of choice for the Rifleman of TV.

Not one American has died of old age since 1951
You used to just plain peter out at 68 or 79 or 93 but, after 1951, the law changed and some Doc had to make up a cause to put on the death certificate. A proximate cause, plus additional lines to fill in for contributing causes/underlying causes of death. (Imagine what that change did to disease stats!) More many more little-known facts about death. Old time Docs knew that people died when they got old and rickety or had a bum ticker or some nasty growths. You plumb wear out eventually, and it is just a matter of which internal doohickey crapped out first. It was considered sort-of natural, and not a medical issue. And, when folks died, they either said "They died" or "They ascended to their Maker" or "Went to their eternal reward." They did not say "They passed" (what a strange expression - passed what? New Agey-sounding, isn't it? Took a pass on more life, or what? Passed into the Spirit World?) or "passed away," as the relentlessly euphemistic funeral home people used to say. Like they aren't dead: they just sort of floated away past the 7-11 and the Pontiac dealership and the Pizza Hut to somewhere else. Maybe to the lovely Mall in the Sky. Tuesday, April 28. 2009A few Modest Proposals for American medical care, plus Didn't your parents teach you that life is a bitch?
It's time we got beyond that self-love, and cared about the Greater Good. I have a few simple, rational, Utilitarian solutions. Cost: Cost is driven by technology and modern pharmacology, cancer treatment, crocks (people obsessed with their health), gomers ("gomers go to ground"), and futile, guilt-driven end-of-life treatment for annoying old or sick relatives. The cost of American medical care can be dramatically reduced by forbidding all cancer treatment other than Oxycontin and at-home 10-gallon morphine pumps, all medical treatment for those over 57 (the children are our future!), all CT and MRI scans, all blood tests, and all medicines other than friendly, holistic, herbal organic ones. No more vaccinations - they cause Autism. No more antibiotics - everybody knows that they make people sick. Eliminate Dermatology (just stay out of the sun, people). Eliminate Opthalmology (bad eyesight is from masturbation - it's your own fault). Eliminate Psychiatry (mental illness is socio-political mind control). Eliminate Urology (do you want a #3 gauge tube stuck up your urethra?). Eliminate Surgery - it is physical assault on comatose victims. Eliminate Neurology - it's just nerves. Access: Doctors are like waterfront trade unions: they limit their numbers to keep their payments high enough to join country clubs, to buy boats, and to take vacations. My idea: anybody who gets a C or better in Organic Chem is automatically admitted to a government medical school. Lots of good, caring people are weak in math and chem and bio and stuff, but that's who we need more of. My medical school flunk-out rate was 18%: what a waste of talent. Plus there are too many Jews and Asians in medicine anyway, and too few people of color or of gender identity diversity. So, with this increase in the numbers of docs, fees could go down to $5 per office visit and the docs who don't like it can open dry cleaning shops, cigar shops and wine shops like they do in Canada. Insurance: Medical insurance is a dumb idea. Why expect your neighbor to pay your medical bills when they will be so low under my plan anyway? They will be cheaper than your garbage pick-up, your newspaper subscription, your cigarette costs, your car payment or your monthly payment for your big screen TV. (Did you ever notice how nobody complains about the cost of their TVs, computers, or Life Insurance?) Or just save your money if you want and die quietly without complaint, dude, and make space for the next generation. Too many people on the planet and, let's face it, life isn't all it's cracked up to be anyway. A vale of tears and toil, a tale told by an idiot, full of sound and fury, signifying nothing. What's the big deal about death? Didn't your parents teach you that life is a bitch?

Friday, April 24. 2009Surgering among the Sioux
Our shrink friend Nathan, who has completed Aliyah in Israel, sends this reminiscence of his days working for the Indian Health Service, doing general practice including surgery and obstetrics - and anything else that was needed. Old-timey medicine.
Before replacing the sloughed skin on Mrs. R's arm, I had to find out why her forearm was raw to the muscle. New here among the Sioux, I am surprised to learn that my colleagues (and one ancient Roman Catholic always fiddling with her rosary) hadn't checked this elderly, chunky widow's blood sugar: diabetic, sure enough, never diagnosed. So, first things first: stabilize her blood sugars, treat the diabetes, and give proper antibiotics (for anaerobes and aerobes -- they missed this too), then when you see the shiny, glimmer of healthy tissue margins, go for a skin flap transplant. Before hitting the OR, I had done several days debriding of the sloughed wound: fresh it must be to transplant the sod of skin. In the OR, flipped on her side, I slid into the vertebral space between L4 and 5; a bit lordotic pull by the nurses and I had a clear tunnel in. Then, flapped on her back, Mrs R. was ready. The thigh well scrubbed, Betadined, aproned, an oval hole isolating the site. Instruments we had. The strange loopy-scalpel to slice just-thick-enough epidermis and a touch if dermis to both "take" to the new site, yet leaving some dermis to heal-over the thigh; something like a large cheese knife the instrument looked. Forearm next. Her arm flung up like some lop-sided angel wing, I probed left-handed with two gloved fingers, then slid the massively long needle --- like from the cartoons -- in between the stretch of skin. Wait. Wait. Numbness without paralysis in the arm. First, a touch on the skin (for sensitive fibers); then a pinch with a forceps (for the pain C-fibers) and success.
It was the only time He has ever spoken around me.

Monday, April 13. 2009Who lacks medical insurance in the US?
Not that the facts matter all that much in politics - and everybody wants a free Easter buffet. Related: How the government plans to create its own medical insurance monopoly. (Just like public schools.) And once they have done that, they will drive through their rationing, rules, and controls. - and freedom in medical care will disappear. At that point, Doctor, your proud and noble profession will be transformed into involuntary servitude to the State rather than voluntary servitude to your patient and, at that point, patient, your treatment choices will disappear. Then watch "doc-assisted" suicide for those over 60 become all the rage in government circles. It's one more government power and money grab. Thursday, April 9. 2009"Quality Care" and Docs with attitude
I see how government "Quality Care" works: the academic medical experts take a vote, and that becomes "Quality Care." That's not medical care: that's government policy. Forget the individual patient and his or her unique situation, forget the Doc's experience and skills and insight, forget the Doc's judgement, forget the fact that academic Docs aren't always practical, forget that next week's new data will completely alter the information at hand. Just Follow The Rules and stay out of trouble. I have seen plenty of cases go bad in the hands of young Docs who strictly follow the rules. It's not a good example of that, but when I was a resident one of "the rules" of the time included strict limits on the use of pain-killers, even for terminal cancer patients. Didn't want them to become addicts, you know. They forgot that pain relief remains one of a handful of the greatest blessings medicine has bestowed on humanity (along with anesthesia, antibiotics - and Lexapro). One of the best things about seasoned physicians is that they are a cranky bunch who do not take orders, who think for themselves, who feel that rules are made to be broken, and who do not like to take crap from anybody - especially anybody in "authority". Your patient comes first, or you are nothing. There is a "House" inside every Doc. In most lines of work, you can't get away with that sort of attitude. When government gets involved in things, they tend to screw them up. The article's example of high blood sugars in the ICU was a perfect example. Even I, who have not cared for ICU patients for more than a decade, know that tight sugar control for critical patients is insane and dangerous. Not only that, but it doesn't matter: if the patient survives and gets healthy, a few days of higher sugars with a good margin of error will not have hurt them one darn bit. But I am a Doc with a practical mind. Expertise always has to be taken with a grain of salt, and government-emitted expertise with a tablespoon-full. I am not disparaging expertise, which I respect enormously. I just distrust the combination of expertise with power over others: anointed experts who want power instead of simply to educate give me the willies. Non-"experts" often have loads of common sense. We take an ancient oath, too. Ed. note: Somewhat related: Socialized medicine: A warning from across the pond

Wednesday, April 8. 2009American MedicineMrs. BD had increasing pain in her right shoulder, then running down her biceps, for two weeks, finally keeping her awake at night. Gets an appointment with the #1 shoulder guy in the world at the Hospital for Special Surgery in three days (last Monday). He is a kind, caring fellow who takes time with her. She gets a shoulder MRI two days later. Gets the diagnosis of early frozen shoulder one day later. Begins physical therapy and anti-inflammatory meds one day later. Feeling better already. Even Fidel Castro couldn't get that kind of care and help, nor could Obama get better. Do I want my neighbor to pay for this for me? No - but thanks so much for offering to pay her bill. I believe in taking care of my own. The bad news for her: no tennis for at least 2 months. The bad news for me: I gotta do all the cleaning and scrubbing, right when it's time to begin enjoying yard and garden work. Well, we have snow flurries today, thanks to Saturday, March 28. 200930 minutes five times a weekThat's the latest cardiovascular recommendation for brisk aerobic exercise. (It used to be 20 minutes three times a week, but new data has changed that recommendation.) I have not asked whether 30 minutes of vigorous sex five times/week counts, but we hope it does.

Tuesday, March 24. 2009Major Medical Insurance: Foolish not to buy itFor some today, and for just about everybody in the past, medical insurance was something everybody bought, just like life insurance or disability insurance, to cover extraordinary expenses. It is called Major Medical, and it is still readily available. Over the past 20-30 years, governments, businesses, and union contracts began expanding their coverage by reducing deductibles and covering more routine things. Medicare, of course, was the model for that. During the same time, costly medical technology and new drugs were developed in a near-miraculous way, mostly in the US. With those changes, folks began wanting "insurance" to cover their routine maintenance medical expenses instead of the things that would financially overwhelm them. When that shift was combined with the CYA style of medicine which results in $5000 work-ups for dizzy spells (fed by the ambulance-chasers), everybody expected everything. That isn't sustainable, and will never happen. Medical technology has grown to an amazing extent, but those machines are expensive. I have no idea what the folks in power are trying to plan for us, but I know it will be an entitlement disaster, filled with unintended consequences, that people would not be happy with. It will end up with politically-determined rationing. Our family bought Major Medical insurance many years ago. It cannot be cancelled. It's more important than a cool car. Why everybody does not do that when they are young and healthy is beyond me, because it would seem like the logical and prudent thing to do. Over the years, we have increased the deductible so that it is quite affordable, and we keep a money market savings account specifically for medical bills to the amount of the deductible. As I recall, we began with a $2000 annual deductible, and now we finally have a dirt-cheap $20,000 2-year deductible on the original policy. It does not cover any routine or preventive medical care, which is as I think it should be. Nobody owes me medical care, in my view, any more than anybody owes me auto insurance. We have kept this policy whether or not I or my husband had some form of insurance through work, because you never know how long you will want to keep a position - or when you will be let go. Off-topic: Around 30% of Medicare expenditures occur in the last year of life. In other words, on failing and terminal people. Interestingly and unsurprisingly, when docs hold end-of-life conversations with these patients (as we should), the costs go way down.

Tuesday, March 10. 2009Top Ten Reasons For ObamaCare Are Based On False InformationGeorge Bernard Shaw warned “Beware of false knowledge; it is more dangerous than ignorance.” The major overhaul of American health care pursued by President Obama and his supporters is based on many false premises and is excessive and likely to do more harm than good. Tuning up and improvements already always dynamically occurs. Instead, ObamaCare is aimed at dramatically changing one-sixth of the US economy in ways that are untested or tested and found wanting, primarily involving huge increases in government direction of health care. The details of ObamaCare are largely being left to Congress, the same body that stuffs the federal budget with earmarks, waste, and other programs that are not requested. ObamaCare is premised on claims for drastic changes in health care and major increases in government programs being necessary. Those claims are largely specious. Below the fold, the top ten specious premises for ObamaCare are discussed:
(More could be added, such as that government restraints on prescription drug prices will not impede incentives for innovations, but they are so transparently false that the list below dwells on other ObamaCare premises more misleading.) Continue reading "Top Ten Reasons For ObamaCare Are Based On False Information" Tuesday, February 10. 2009Vitamins
Docs have been poo-pooing routine vitamin-taking for many years. We tend to think of it as a rip-off (although I do take a daily Vit D). Studies continue to indicate their uselessness in adulthood, but the placebo effect cannot be underestimated.
Dems vs. Doctors (and your medical privacy)
If they want docs to give up their autonomy, they had better find a new, lesser breed of docs in this country. And I'd rather fight with an insurance company about my medical choices than fight with a federal bureaucrat. If the insurance company doesn't want to pay, I can at least pay for it myself. Tuesday, January 6. 2009Do you want a "Hospitalist"?
I have yet to be a hospital inpatient except for childbirth, but I think that, if and when I am, I'd like to see the face of my own Doc daily. This is a new model for medical practice. More time-efficient? Probably. Less comforting? Probably. Overall, better or not? I cannot say. Internists, and what few GPs still exist, are having a tough go of it these days: Medicare, which is the bulk of their work, compensates them now at a rate lower than a plumber or electrician in Boston.

Friday, December 5. 2008Alcohol and the HeartYour doctor may be so concerned about protecting you from alcoholism that he or she might not tell you that current research indicates that 1-2 drinks per day appears to reduce the risk of heart and arterial disease by 18-30%. More is not better, however. Details at Medscape. Monday, November 17. 2008More on Statins

Saturday, November 15. 2008Cranberry Season, and the HeartRe-posted from November, 2005
As a native Cape Codder and cranberry fan, it's a delight to report that they may have a powerful anti-atheroscletotic effect. Maybe this news might have a beneficial effect on a specialized family farming that has been bedeviled by low prices. The big producers are Wisconsin, Massachusetts, New Jersey, Washington, Oregon and Michigan. The sentence in Science Daily I don't understand is the following: "The researchers said that the next step is to determine which compounds in cranberries contribute to the benefits and then figure out how to incorporate them into the diet in a form palatable to humans." How about in cranberry juice, cranberry muffins, cranberry pancakes, 25 kinds of cranberry sauce, cranberry cobbler, and dried cranberry "raisins,"....for starters? You can buy unsweetened, undiluted cranberry juice now in most supermarkets. We keep bags of them in the freezer, and they seem to last a year. Cranberry sauce: it's not just for Thanksgiving turkey. It's good for chicken and almost any kind of game meat. Never use the junk from the can, though. Even if you think you like it, you will find you like the home-made far better. More on this native North American wetland plant here. Saturday, October 11. 2008Saturday Verse: Crazy Jane (and the evolution of the anus)David Thompson led us to a report about the evolution of the anus. How did critters get from one opening to two? One theory presented is that it entailed a connection between the GI tract and the reproductive system. Many animals, like birds and reptiles, have a cloaca (or "vent" - hence the word "venting"), which combines urinary, defecatory and sexual functions. (Most birds copulate via a "cloacal kiss," but a few lucky birds, notably ducks, swans and ostriches, have penises.) This reminds me of the Yeats: Vl: Crazy Jane Talks with the Bishop

Tuesday, October 7. 2008The Fannie-ization of Health CareFrom guest author Bruce Kesler:
The forces in the credit crisis were the appeal to provide opportunities for home ownership to the poor and the consequent inflation of housing values that provided paper gains to the middle class and wealthy. Underlying these forces was a pyramid scheme profiting the political and financial elites that was dependent on trust in repayment of subprime loans by many without the means or stake in doing so.
Thus, ultimately the taxpayer and more careful consumers and investors are required to pay off, also making other worthy goals unaffordable. Continue reading "The Fannie-ization of Health Care" Thursday, September 25. 2008Beauty Studies
A quote from Beauty and the Brain (by the proprietor of Neurophilosophy) in Seed (h/t, Dr. X):
Can things of the soul and spirit be understood in terms of neurotransmitters and neural wiring? Count me a skeptic. Different levels of organization have different rules and patterns which do not transfer one to the other. For example, you could know everything about atoms but never predict a living cell, and you could understand everything about a cortical network without predicting Moby Dick. (And, for me, on a good day I see beauty everywhere but on a bad day I see it nowhere.) Still, they may as well give it a try. I get skeptical when they call it a bio-cultural model, however. It makes it too clear that they seek to detour around the psychology part. Monday, September 22. 2008Got teeth?
Teeth are a sensitive subject. When you lose one as an adult, you feel a bit emasculated. Lose a handful, and you can develop a clinical depression. And root canals are a torture which even the CIA would never inflict on Osama. My first one was without Novocaine at age 14. The elderly dentist didn't "believe in" Novocaine. I have had plenty since then. Plus it costs big bucks to keep good teeth after 45, unless you are one of the lucky ones with genetically strong enamel. My teeth are mediocre-to-poor. I have one implant so far, many crowns, and a number of failing crowns. My wisdom teeth were pulled years ago. I have some extractions and two more implants on the way, plus a bridge. Most of my teeth have fillings and miscellaneous repairs. My dentist blames it on cigars and bad tooth genes, and says I need a serious big-time periodontistry before he can do any more repairs and reconstruction. I also lost a few front ones playing hockey in prep school. The brother of my then-girl friend stuck the end of his stick in my face, entirely by accident no doubt. Whenever I am sent to a new person, eg a periodontist or an implantologist or an oral surgeon, before I open my mouth I always say "Promise you won't say 'Oh my God what a mess.'" This stuff gets expensive. But even worse is that it is a depressing reminder of ones' aging and deterioration, a memento mori. Entropy always wins. We pay and struggle, but we always lose the battle.

Thursday, September 18. 2008The French SystemPeople talk about the Canadian system (horrible for Docs and patients) and the NHS (which 56% of Brits want eliminated). Few discuss the way the French do it, but it's worth thinking about. Part 1 of Health Care Reform discusses the history French system, noting "They emphasize private, fee-for-service practice even more than we do." If you are interested in the topic, Synthstuff links all 4 parts of this essay, written by a Doc who likes the system. Monday, September 15. 2008Medical costsRobert Samuelson, in Getting Real about Health Care: It's not about coverage. It's about cost, begins:
Read the whole thing. Of course, the only way to control costs is to limit services. HMOs do that, and people rebel. Besides freedom, what do American people value more than their health (well, plus their guns and Bibles)? Sunday, August 24. 2008A re-post: The Risks of Action vs. Inaction, Part 2 of 3: Appendicitis, False Positives, False Negatives, and Type l and ll Errors
That seems to be human nature, but it ain't rational and, fortunately, people vary across a spectrum of activity/passivity. Passive people worry about the risks of action. Active people worry about the risks of inaction. I am more-or-less in the middle. To discuss that half-intelligently, though, I first need to review the notion of Type 1 and Type 2 errors, now that we have taken a look at the null hypothesis a couple of days ago. A Type 1 error, also known as False Positive, is the error of erroneously rejecting the null hypothesis. In other words, it supports a connection which does not really exist. A Type 2 error, or False Negative, is the error of wrongly accepting the null hypothesis. In other words, it says nothing is there, when it is, in fact, there. For example, a blood test which has a 10% False Positive rate will wrongly tell you that there is an abnormality 10% of the time. A blood test with a 10% False Negative rate will miss an abnormality 10% of the time. For another example, convicting an innocent person is a Type 1 error; letting a guilty person go free is a Type 2. Depending on the matter at hand, either sort of error could have worse consequences. A Type 1 error in a death penalty case is a grievous error. But sometimes you need Type 1 errors. My favorite example of a good Type 1 error is in the emergency treatment of appendicitis. Since medical diagnosis contains both art and luck as well as science, some error rate is inevitable unless you have the diseased organ in hand. But since a False Negative diagnosis would have dire consequences (ruptured appendix), it is necessary to do some unnecessary appendectomies on patients who might have appendicitis, but do not turn out to. In the case of emergency appendectomies: one study indicates that the Type 1 error rate is around 10%, with 18% False negatives. I would have guessed that the False Positives would be higher, and you could argue that there is room for them to go higher. The point is that, with appendicitis, you want to minimize your False Negatives by having more False Positive diagnoses - by being deliberately biased against the Null Hypothesis that there is nothing there, but without cutting open everyone with a bad stomach ache. Thus that is the opposite of what you want in a justice system, where the null hypothesis of innocence is presumed in order to minimize False Positives.

Saturday, August 23. 2008Diagnostic Errors: A re-postDiagnostic errors remain the All the more reason for docs to be irrational - or rationally irrational - in spending your money (either yours directly, or the insurance company's money - which was your money). If you have a headache, I am going to order an MRI of your head which will cost you between $700-1100 in my area. I know darn well that you don't have a tumor, but I could be wrong 0.3% of the time. So I'll order the MRI, because you will want me to, and my law suit defensiveness will want me to. Still, I will know that it is poor medicine. Indeed, I know that your particular pattern of headache, and your exam shows it to be a Common Migraine, and not a tumor, not an aneurysm, not a stroke or subdural, etc. And I know that all sorts of guidelines have been constructed, such as these. Well, you can toss the guidelines for all I care. The Barrister's recent series on error (Part 1 - Fun with the Null Hypothesis, applies beautifully to modern medicine. There is almost no end to the amount of your money we can spend to try to reduce our False Negative rates - our Type 2 errors. And they will occur, regardless. It is very unpleasant to be sued. It damages a doctor's enjoyment of his art, it absorbs huge amounts of time and energy, and it damages his relationships with all of his patients. And, finally, it has nothing to do with his competence and everything to do with the greed and litigiousness of his patient. I pay 42,000/year for malpractice insurance as a GP, and I have never been sued. I know guys who pay 160,000. You are paying those bills.

Thursday, August 14. 2008How autistic are you?There are tests of your social situational sensitivity. I know, and like, people from across the spectrum. And severely autistic people are still people. Nobody's wiring is perfect. How could it be? What obesity "crisis"? Nowadays, everything has to be a crisis.
Nowadays you can define anything you want as pathological. And this whole new fashionable category of "at risk" silliness expands things to include everybody. For example, at middle-age I am "at risk" for obesity. Not wanting to be fat, I decided not eat carbs and I do a tough daily workout. It's not too complicated. Prosperous nations have lots of fat people. More of them than poor nations, although poor nations have plenty of them too. The reason is that humans have a weakness for carbs. Thus being trim and fit is a sign of self-control, but being heavy is a time-honored sign of prosperity. If you want to see fat people, go to Disneyworld and get grossed out. There are Americans there so fat that they have to ride around in motorized chairs, like King Kamehameha. God bless 'em. The world needs more fatties, in my opinion. It means people have plenty to eat, but I don't like to have to look at them. To be evenhanded, however, I find anorectics even more disturbing. I happen to feel that excess fat in women is unattractive, slovenly, and unsexy. Somewhat less so in men: some stout men are cool, like Teddy Roosevelt was. Anyway, we have been subject to much brouhaha about obesity in recent years. Big health crisis, etc. You have surely read the news that being overweight is not such a big deal, from a medical standpoint. Even the WSJ covered the story, amusingly. Obesity - and that means much more than ordinary fatness and pudginess - is often quite benign. And being overweight is fine, from a health standpoint. Just like the the AGW fad and all such fads that governments are suckered into, there is fat money to be made from the obesity silliness. Follow the money: you know that somebody always wants some of yours. Careers. Respect. Pensions. Fat City. Fact is, when I was an intern in NYC, I saw plenty of skinny, athletic guys in their 40s come into the ER and crap out with massive heart attacks. Also, skinny guys with insulin resistance. The reasons to be relatively thin are to be fully functional - and aesthetic. If an American lady wishes a decent sex life, it behooves her to be trim. Not so in some countries, however, where they prefer us gals Biggie-Sized. Here's a good food story, from the Englishman:
Let's all be relaxed and tolerant: being fat is a "life-style" choice. Let them eat cake. Addendum: At Pajamas, Fast food restrictions fatten government

Saturday, July 26. 2008Sex (in Britain)A re-post from 2005: Norm has posted some interesting data from a recent study on the differences in libido between men and women. The results sound like that medical research spoof about the 20-year, 70 million dollar government study which proved the surprising fact that diet and exercise are important for weight loss. This new study offered the startling conclusion that men have higher sexual needs than women. More specifically, the study says that men need sex every five days, and women every ten. My opinion: This study only applies to Brits.

Thursday, July 24. 2008How do statins work?
Well, it's a good idea to take them. It may turn out to be a good idea even if your cholesterol and triglyceride levels are in the normal range. Why? Because the way they seem to reduce arterial disease leading to heart attack and stroke may not be just - or even mainly - so much by altering cholesterol and triglyceride blood levels, but by stabilizing the endothelium (inner lining) of arteries. Here's a technical paper on the subject. One quote:
The inflammation, clots, and plaque on arteries are the main cause of terrible events. American males already have visible arterial disease in their 20s. I saw it and touched it when doing autopsies in medical school, in young people who died of other causes. Everybody dies. Statistically, if you reach maturity and don't die in a car crash, the odds are that half die of cancer and half of heart/arterial disease. So, if you can postpone that arterial disease, you get to die from a cancer. That's today's cheery medical news. Saturday, July 5. 2008The Special Ed WarsHope our readers are enjoying this weekend. I am going for a ride over hill and dale and field and fountain with the Mrs. in an England-like cool foggy drizzle in a moment, but Jack, our Quarter Horse, looks a little lame this morning - maybe it's a sore hoof - and I'm not sure which animal I want to mess with today. But I wanted to make sure to post this link to a discussion about Special Ed and "special needs" kids. I have a number of friends and acquaintances who are dealing with PDD and autism and the like in their kids and grandkids. The author of this piece at Pajamas has personal experience as the parent of a disabled kid. Saturday, June 28. 2008Scratch that itchThink about it for one second - don't you have a little itch somewhere on your skin right now? It's considered poor manners to scratch in public, but sometimes you just have to do it. I am not watching you. Learn all the latest about The Itch. Thursday, June 26. 2008Death and Government Medicine - Updated
Dr. Bob discusses. One quote:
In my view, easy abortion was the first big step in the direction of removing the annoying inconvenience of a human life. Perhaps it would be most expedient - or utilitarian - to do us in the minute we stop paying income taxes...assuming our function is to serve the "common good." Or at the moment of our birth, because it is certain that we will become expensively ill someday. And when it comes to medical treatment in general, I like TigerHawk's idea much better than any governmental idea. WallMart! Just as long as I have my own doc who knows me and cares about me first. Addendum: Father of Canada's medical system rejects what he created. "Woops. I goofed. So terribly sorry."

Tuesday, June 24. 2008Tanning and Cancer
Here's a piece at Pajamas on the subject. The take-home message is, I believe, get tan but not burned. It's good news, because those of us who are pasty-white Anglos look better with some healthy color. Sunday, June 1. 2008"Pinkapalooza," debunked
A friend who has had breast cancer sent some quotes from the book, with the comment: "I Finally Found My Club! Good laughs @ all the BC bullshit. Thought this book might be helpful if you know others who aren't using their B.C to accomplish a spiritual makeover... & don't expect B.C. to fix what's wrong w/ them."
I tend to agree with Ms. Lewis. Bad disease is a plain bad deal. Scary (if you like life), with little redeeming about it.

Friday, May 16. 2008MiracleHow DNA works (a big h/t to Flares for finding this). You can tell me all day long that existence is simply mechanical and not a miracle, but I won't buy it. At the end of this bit, at the bottom of the YouTube screen, click on the other DNA and protein-construction videos. It's Biochem 101, without the details. Amazing visualizations, I think. Sunday, May 11. 2008Sunshine is good for youWe said this a month ago. Will you believe it if it comes from Instapundit?
Which do you believe? Last year's expertise, or this year's? I am inclined to trust this year's, or God would have put sunscreen on our skin. Monday, May 5. 2008The one cure-all, including for your sex lifeI know that it is trite to tout exercise, but it is worth mentioning that we keep learning more about its health benefits. I recently attended a talk on breast cancer in which daily exercise compared favorably with several widely-used chemotherapy protocols. Humans were not designed to sit on their butts all day watching TV or reading ephemeral stuff on the Internets. You name it, and exercise helps it, in the NYT by Jane Brody.

Friday, April 4. 2008"Ignored relatives vainly tried to have the old man declared insane"John Masterson Burke (1812-1909) led a long and successful life with many prominent friends and business associates, including Russell Sage and the Vanderbilts. He never married, had no close relatives, and lived in a spartan manner in Manhattan. He left his $4.5 million estate in the name of his mother "for the establishment of the Winifred Masterson Burke Foundation, which is to be a rest home for convalescents..." The inspiration for his idea is unknown. Today, The Burke Rehabilitation Center in the NYC suburb of White Plains, NY is the premier rehabilitation and rehabilitation research center in the world. A dear and close relation of mine is there right now, post hip-replacement and, if you have any doubts about American medicine, you will not after you see how this amazing place works. It's interesting to read Burke's 1909 New York Times obit. Annoyed distant relatives came out of the woodwork after he wrote his final will. Also wonderful to read the Victorian language (eg "will says he gave money to restore health, not for enjoyment") in this New York Times report on his bequest. Thursday, March 27. 2008VitaminsThought I might share the data from a meeting tonight about vitamins, health, and cancer. The short version: - Do not take folate-containing supplements unless you are bearing babies. (Unfortunately, the government in its infinite wisdom mandated its addtion to bread and other foods for the benefit of child-bearing women who eat terrible diets.) That's just one researcher's opinion, of course. Friday, March 21. 2008Free whole bodyNeurophilosophy reports:
