Smoking: A half century of knowing we should quit

In 1950 Ernst Wynder MD and colleagues began to produce convincing data that cigarette smoking caused lung cancer. Over the ensuing many years evidence has arisen linking cigarette smoking to many different cancers and conditions, chronic lung disease and heart attacks. In 1964 the surgeon general reported that cigarette smoking was the most important risk factor for development of lung cancer and that quitting smoking reduced that risk. Since that time a concerted effort to reduce tobacco smoking has been one of the most important public health agenda items for the medical profession. Since this is the 50th anniversary of organized tobacco control, the Journal of the American Medical Association has devoted an entire issue to the subject of tobacco and health.

Articles include a survey of smoking prevalence around the world: US residents smoke less than people in Europe, especially Eastern Europe. Although many Africans smoke, they don't smoke much, Women generally don't smoke as much as men, except possibly in Eastern Europe. There were a pair of articles discussing eCigarettes, the nicotine delivery devices that look vaguely like cigarettes but don't burn tobacco. One article expressed the strong conviction that eCigarettes should be regulated by the Food and Drug Administration (FDA) because their long term safety has not been studied, especially in adolescents, their public use makes people accept a smoking-like activity in public places where it is now prohibited and many people who smoke eCigarettes also smoke tobacco so perhaps the delivery of nicotine allows ongoing addiction. The other article suggested that eCigarettes might be a "disruptive technology" and might entirely replace burning tobacco, with its associated health risks. Digital photography was a similar disruptive technology and has successfully nearly replaced film photography due to its competitive cost and improved convenience and adaptability. The authors felt that increased regulation of eCigarettes might serve to bolster the market share of the tobacco industry, with significant negative impact on the health of the smokers who are likely to abandon tobacco for a cheaper and more convenient alternative.

Other articles looked at the usefulness of two drugs, bupropion and varenicline, to promote and support cigarette abstinence. These drugs have been available for years, along with nicotine replacement, to help smokers quit and have been moderately helpful.

The most thought provoking article of the collection was written by two authors, Andrea L. Smith and Simon Chapman, of the Public Health School of the University of Sydney in Australia. They point out that the vast majority of patients who have quit smoking have done so entirely unassisted. No support groups, no drugs, no counseling. In a 2013 Gallup poll, 48% of successful quitters stopped "cold turkey" because they decided it was time. 5% used nicotine replacement and only 3% used drugs. The authors noted that the Australian government spends a vast amount more money on the drugs prescribed to help patients quit than on social marketing campaigns which would make them want to quit. Apparently the US is not alone in its belief that we need pharmaceuticals to make us well. Buying drugs which don't work and require that patients visit doctors for prescriptions and counseling is revenue generating. Successfully quitting "cold turkey" is not.

In 1964 Americans first got the message from the surgeon general that they should quit smoking to reduce their risk of lung cancer. The response to this message was huge. In 1964 42.7% of adults smoked and today that number is 18.1%. Average daily cigarette consumption among smokers has also dropped, from 20 to 13. We have seen a significant reduction in death rates associated with smoking related diseases. The vast majority of smokers consider themselves to be addicted and would like to quit. The huge number of patients who have successfully quit have reduced their risk of heart attack, stroke, cancer and lung disease significantly. A group out of Yale University modeled the number of premature deaths prevented by tobacco cessation since 1964 and they estimate that 8 million lives were saved. These were people who didn't get cancer, didn't need oxygen tanks, didn't have to undergo radiation treatment or chemotherapy, have bypass operations, struggle to walk up hills due to shortness of breath or heart pain. What a lot of people need thanks for this: doctors who diligently nagged patients, researchers who followed up leads conscientiously, advocates who countered tobacco company rhetoric, public health specialists who made the story interesting, and most of all smokers who decided to quit, because it was time.

How to make your own ultrasound gel (which is also sterile and edible and environmentally friendly) **UPDATED--NEW RECIPE**

I have been doing lots of bedside ultrasound lately and realized how useful it would be in areas far off the beaten track like Haiti, for instance. With a bedside ultrasound (mine fits in my pocket) I could diagnose heart disease, kidney and gallbladder problems, various cancers as well as lung and intestinal diseases. Then I realized that I would have to take a whole bunch of ultrasound gel with me which would mean that I would have to check luggage, which is a real pain when traveling light to a place where luggage disappears. I heard that you can use water, or spit, in a pinch, or even lotion, though oil based coupling media apparently break down the surface of the transducer. Or, of course, you can just use ultrasound gel. Ultrasound requires an aqueous interface between the transducer and the skin or else all you see is black. Ultrasound gel is a clear goo, looks like hair gel or aloe vera, and is made by several companies out of various combinations of propylene glycol, glyce...

Actinic Keratoses and Carac (fluorouracil) cream: why is this so expensive?

First, a disclaimer: I don't know why Carac (0.5% flourouracil cream) is so expensive. I will speculate, though, at the very end of this blog. Sun and the skin: what happens If a person reaches a certain age, has very little pigment in her skin, and has spent lots of time in the sun, bad stuff happens. The ultraviolet radiation of the sun does all kinds of great things: it makes us happy, causes us to synthesize vitamin D which strengthens our bones and it gives us this healthy glow until we get old and wrinkled and leathery. And even that can be charming. The skin cells put up with this remarkably well for a long time, partly aided by melanin pigment which absorbs the radiation, which is why we tan and freckle, if we are fair skinned. Eventually, though, we absorb enough radiation that it injures the skin and produces cells which multiply oddly. It also damages the skin's elasticity which creates wrinkles. The cells which reproduce in odd ways peel, creating dry skin or...

More reasons why Medicare costs are too high: hospice care is grossly overpriced

Care of the dying is one of the most important jobs that a physician or nurse can have. Death, like birth, is a momentous and sacred transition, and good care can give peace and comfort to the patient as well as to his or her family and friends. The dying process is often painful and frightening and good, knowledgeable support can alleviate suffering for all involved. Hospice care has evolved since its inception in the 1400s to embrace support of the dying both in designated facilities and in patients' own homes. Once a patient and his or her doctor have come to accept that a disease is terminal and that death is imminent (usually 6 months of expected life left) hospice care can usually be arranged to allow a patients last days or months to be as pain and anxiety free as possible, providing caregivers with the help and support they need. Hospice services usually include home visits by nurses and nurse's aids, medications for symptoms control, social worker visits, grief couns...
