Train Therapy

Summertime and the living is busy.  Finally we have sun in the Northwest.  While the rest of the country has been melting in heat, this year we have rarely cracked 85.  Global heating has avoided Oregon this year, and I will need some green tomato recipes.  Good weather, work is busy, and it is the last two weeks with my eldest before he is off to Syracuse, so there is little time for writing, so a brief entry this week.

I always wince at the way anything can be called ‘therapy.’ We have music therapy and garden therapy and pet therapy and art therapy.  I do not deny that it is beneficial for people to participate in those activities while in the hospital, although I am never happy to see disease vectors, er, animals in a hospital.   Dinner should be food therapy, reading should be book therapy, and using the internet should be computer therapy.  I guess it is like calling something ‘medical’ grade, and you can bill more for it.

Some ‘therapies’ are a wee bit more odd.  Indonesians are using railroad therapy.  People lie down on electric railroad tracks because “the electricity current from the track could cure various diseases.”  To date no one has been either electrocuted or squashed, but I suppose it is only a matter of time.

CAM: The Beer Goggles of Medicine

It is summer, the kids are off, and time to write dwindles in the face of sun and golf. Nonsense knows no season, and in my readings this week I came across the phrase “the undeniable power of the placebo.” I will do my best to deny that power at least three times before the I crow my conclusion.

One of my first entries for SBM, back in the mists of time, was the Placebo Myth [0], where I argued that the placebo has no clinical effects, has clinically irrelevant alleged physiology and at most leads to a slight change in perception on the part of the patient that they have less pain. Essentially placebo does nothing. It has no power.

Two studies this month continue that argument: demonstrating that placebo has no practical benefit and the crowing in the media mistakenly trumpets that it does. The headline on Medscape [1] reads “Placebo Effects Modest in Treating the Common Cold.” How modest?

Honey

I cram for TAM, and, combined with other commitments, not the least of which is that it is finally sunny and warm in Portland, after a year that has resembled All the Summer in a Day,  which leads to a relatively short post.  There are just so many hours in a day and if possible those days need to be spent in the sun.

In my first year in practice I was sitting on a nursing station writing a note when a patient started howling in pain.  Further investigation revealed that the patient had a chronic, open surgical wound and the (old) surgeon had ordered sugar poured into the wound as part of wound care.  The cafeteria mistakenly sent up salt, and a metaphor became reality.  It did pique my interest in both sugar and honey for wound care,  an area where you have to be careful not to fall prey to all the errors in CAM thinking: a reliance on anecdotes, using suboptimal studies as evidence, mistaking a gobbet of basic science as a meaningful clinical application, and not realizing the warping effect of confirmation bias.

That being said, I have suggested honey and sugar for years for patients, and many patients with prior refractory wounds had healing.  And what are the three most dangerous words in medicine?  In my experience.  I have recommended honey less in the era of the wound vac, but there are not an insignificant number of people with insufficient financial resources who cannot afford even simple wound care supplies. Many  of the ointments, creams and special bandages for wound care costs too much.  Patients also like honey as it is natural (people do love to fall for the naturalistic fallacy) and inexpensive, and I always tell patients that the data is iffy, but not stupid.

SOS DD

What does it take to become a doctor?  Endurance and perseverance help. It is a long haul from college to practice.  But the skill that is most beneficial is the ability to consume prodigious amounts of information, remember it, and recall it as needed.  Although I often relied on ‘B’ to get me through some of the exams.

Thinking, specifically critical thinking, is not high on the list of abilities that are needed to become or be a doctor. Day to day, doctors need to think clinically, not critically.  Clinical thinking consists of synthesizing the history, the physical and the diagnostic studies and deciding upon a diagnosis and a treatment plan.  It is not as simple as you might think.  When medical students start their clinical rotations and you read their notes, you realize they have what amounts to an advanced degree at Google U.  They know a huge amount of information, but have no idea how the information interrelates and how to  apply the that information to a specific clinical scenario.  With time and experience, and it takes at least a decade, students become clinicians and master how think clinically, but rarely the need to think critically.

The volume of data combined with time constraints ensures that we need to rely on the medical hierarchy to help manage the information overload required to apply science and evidence based therapy.  There is just to much data for one tiny brain to consume. Other doctors rely on me for the diagnosis and treatment of odd infections.  In turn, I  rely on the published knowledge and experience of my colleagues who have devoted a career to one aspect of infectious diseases.  There is little time for most doctors to read all the medical literature carefully, and usually little need.  We have people and institutions  we use as surrogates.

Not only is critical thinking usually not required to be a good physician, but medical practice can conspire to give physicians a false sense of their own abilities.  Really.  Some doctors have an inflated sense of self worth.  Who would have thought it?  Spend time with some doctors and listen to them pontificate on politics or economics with the same (false) assurance that have in their true field of expertise, and you will run screaming from the room.

The Dow of Accutane

At home the kids current TV show of choice is How I Met Your Mother, supplanting Scrubs as the veg out show in the evening. Both shows are always on a cable channel somewhere and are often broadcast late at night. Late night commercials can be curious, and as I work on projects, I watch the shows and commercials out of the corner of my eye.

Law firms trolling for business seem common. If you or a family member has had a serious stroke, heart attack or death from Avandia, call now. The non-serious deaths? I suppose do not bother. One ad in particular caught my eye: anyone who developed ulcerative colitis or Crohn’s disease (collectively referred to inflammatory bowel disease, or IBD) after using Accutane, call now. Millions have been awarded.

My eye may have been caught because of my new progressive lenses, but I will admit to an interest in inflammatory bowel disease, having had ulcerative colitis for years until I took the steel cure. It also piqued my interest as these were three conditions among which I could not seen any connections. Accutane, ulcerative colitis, and Crohn’s. One of these is not like the other.

Ambiguity

Some people have made the mistake of seeing Shunt’s work as a load of rubbish about railway timetables, but clever people like me, who talk loudly in restaurants, see this as a deliberate ambiguity, a plea for understanding in a mechanized world. The points are frozen, the beast is dead. What is the difference? What indeed is the point? The point is frozen, the beast is late out of Paddington. The point is taken. If La Fontaine’s elk would spurn Tom Jones the engine must be our head, the dining car our esophagus, the guard’s van our left lung, the cattle truck our shins, the first-class compartment the piece of skin at the nape of the neck and the level crossing an electric elk called Simon. The clarity is devastating. But where is the ambiguity? It’s over there in a box. Shunt is saying the 8:15 from Gillingham when in reality he means the 8:13 from Gillingham. The train is the same only the time is altered. Ecce homo, ergo elk. La Fontaine knew his sister and knew her bloody well. The point is taken, the beast is moulting, the fluff gets up your nose. The illusion is complete; it is reality, the reality is illusion and the ambiguity is the only truth. But is the truth, as Hitchcock observes, in the box? No there isn’t room, the ambiguity has put on weight. The point is taken, the elk is dead, the beast stops at Swindon, Chabrol stops at nothing, I’m having treatment and La Fontaine can get knotted.

— Art Critic

Ambiguity. Medicine, like art, is filled with ambiguity, at least the way I practice it. Most of my practice is in the hospital. I am sometimes called to see patients that other physicians cannot figure out. And that puts me at a disadvantage, because the doctors who were referring patients to me are all bright, excellent doctors. Often the question is ‘Why does the patient have a fever?’ or ‘Why is the patient ill?’ Sometimes I have an answer. Most of the time I do not.

I am happy, however, to be able to tell the patient what they don’t have. I can often inform the patient and their family that whatever they have is probably not life-threatening or life-damaging, just life-inconveniencing, and most acute illnesses go away with no diagnosis. I always put the ‘just’ in air quotes, because illnesses that require hospitalization are rarely ‘just.’ Just without quotes is reserved for the antivaccine crowd and applied to the small number of deaths from vaccine preventable diseases in unvaccinated children. John Donne they ain’t.

We are excellent, I tell them, at diagnosing life-threatening problems that we can treat, and terrible at diagnosing processes that are self-limited. Of course diagnostic testing is always variable. No test is 100% in making a diagnosis, and often with infections I cannot grow the organism that I suspect is causing the patient’s disease. So for hospitalized patients, ambiguity and uncertainty are the rule of the day. (more…)

Raw Milk in Modern Times

It is hard to get infected. The immune system is robust and has a multitude of interlinking defenses that are extremely efficient in beating off most pathogens. Most of the time.

Fortunately, it is a minority of microbes that have evolved to be virulent in humans. Bacteremia is common with our own microbiome. When you brush or floss, bacteria leak into the blood stream:

We identified oral bacterial species in blood cultures following single-tooth extraction and tooth brushing. Sequence analysis of 16S rRNA genes identified 98 different bacterial species recovered from 151 bacteremic subjects. Of interest, 48 of the isolates represented 19 novel species of Prevotella, Fusobacterium, Streptococcus, Actinomyces, Capnocytophaga, Selenomonas, and Veillonella.

but with a good immune system, low virulence bacteria and no place to go, unfortunately the bacteria rarely cause infections.

Even heroin users rarely get infection. Heroin is a rich melange of  with bacteria and, on occasion, yeasts (I hate to say contaminated, since avoiding microbes is hardly a worry of heroin manufacturers), and the water used for injection is rarely sterile, yet infections are relatively rare despite the filth in which many heroin users exist.

I used to be somewhat fatalistic about hospital acquired infections. However, as the institutions in which I have worked have proven, almost all infections in the hospital are preventable if the institutions aggressively pursue high standards of care.

There are many systems in place in society to prevent infections: flush toilets, good nutrition, public health, vaccines, antibiotics, good hygiene, and an understanding of disease epidemiology, and I suspect people forget there are bugs out there that are pathogenic, just waiting to sicken and kill us. At least a couple of times a year I see patients come into the hospital, previously healthy, who rapidly die of acute infections.  But for most people, most of the time,  it takes a lot of effort to get an infection.

From my perspective we are Charlie Chaplain on skates , mostly unaware of the infections that awaits us if we do something silly, or even when we act with the best intentions to avoid illness. The odds are small we will get a life threatening or serious infection in the US, just as the odds are small we will drown or be killed in a car accident. The germs are there, waiting, and in the end, no matter what we do, we will be consumed by the microbial world. (more…)

Parasites

I saw a patient recently for parasites.

I get a sinking feeling when I see that diagnosis on the schedule, as it rarely means a real parasite.  The great Pacific NW is mostly parasite free, so either it is a traveler or someone with delusions of parasitism.

The latter comes in two forms: the classic form and Morgellons. Neither are likely to lead to a meaningful patient-doctor interaction, since it usually means conflict between my assessment of the problem and the patients assessment of the problem.  There is rarely a middle ground upon which to meet. The most memorable case of delusions of parasitism I have seen was a patient who  I saw in clinic who, while we talked, ate a raw garlic clove about every minute.

“Why the garlic?” I asked.

“To keep the parasites at bay,” he told me.

I asked him to describe the parasite.  He told me they floated in the air, fell on his skin, and then burrowed in.  Then he later plucked them out of his nose.

At this point he took out a large bottle that rattled as he shook it.

“I keep them in here,” he said as he screwed off the lid and dumped about 3 cups with of dried boogers on the exam table.

To my credit I neither screamed nor vomited, although for a year I could not eat garlic.  It was during this time I was attacked by a vampire, and joined the ranks of the undead. (more…)

Without Borders

Take up the White Man’s burden–
The savage wars of peace–
Fill full the mouth of Famine
And bid the sickness cease;
And when your goal is nearest
The end for others sought,
Watch CAM and woo Folly
Bring all your hopes to nought.

The White Man’s burden, a bit of racism from the 19th century:

The term “the white man’s burden” has been interpreted as racist, or taken as a metaphor for a condescending view of non-Western national culture and economic traditions, identified as a sense of European ascendancy which has been called “cultural imperialism.” An alternative interpretation is the philanthropic view, common in Kipling’s formative years, that the rich have a moral duty and obligation to help “the poor” “better” themselves whether the poor want the help or not.

I will let the commentators debate the meaning of the poem. There are places in the world so devastated by poverty, disease and political corruption that it may be beyond the capacity of the local populations to overcome. They need outside help. Certainly, the impulse to help those less fortunate than yourselves is a noble tradition. Haiti, Central America and Uganda are parts of the world that need assistance in overcoming an incredible number of problems to reach even a basic level of material support for its population.

The World Has Moved On

I do a lot of driving as part of my job.  I am the sole Infectious Disease doctor at three hospitals and I can spend an hour or two a day in the car, depending on traffic.  What prevents me from going crazy sitting in traffic is listening to podcasts and audible books.    I especially like reading (and yes, audio books is reading, pedant) multivolume epics.   Currently I am reading Steven King’s Dark Tower series, which occurs in a universe “where the world has moved on.”  In Mid-world there was once a world with science and beauty and art, but something changed, what I do not know yet (I am only on the third volume; no spoilers in the comments), and the world moved on, leaving behind some artifacts of science and technology, but it appears to be an increasingly primitive world.  Being fantasy, there is, unlike the world I live in, magic as well.

I like that phrase: “the world has moved on.” (more…)
