Steve Jobs’ medical reality distortion field

As I pointed out in my previous post about Steve Jobs, I’m a bit of an Apple fan boy. A housemate of mine got the very first Mac way back in 1984, and ever since I bought my first computer that was mine and mine alone back in 1991 (a Mac LC), I’ve used nothing but Macintosh computers, except when compelled to use Windows machines by work—and even then under protest. Indeed, as I searched for jobs at various times in my life, I asked myself whether I could accept a job at an institution that didn’t permit me to have a Mac in my office, such as the V.A. Fortunately, I never had to make that choice. All of this explains why I paid a lot of attention to Steve Jobs and also why his death saddened me and, relevant to this blog, the clinical history of the cancer that killed him fascinates me.

It’s often been said that there was a sort of “reality distortion field” around Steve Jobs. It was a part joking, part derogatory, part admiring term applied to Jobs’ talent for persuasion in which, through a combination of personal charisma, bravado, hyperbole, marketing, and persistence, Jobs was able to persuade almost anyone, even developers and engineers, of almost anything. In particular, it referred to his ability to convince so many people that each new Apple product was the greatest thing ever, even when that product had obvious flaws. Unfortunately, as more news comes out about how Steve Jobs initially dealt with his diagnosis of a neuroendocrine tumor of the pancreas (specifically, an insulinoma) back in 2003 and 2004, it’s become apparent that Jobs had his own medical reality distortion field, at least in the beginning right after his diagnosis of a rare form of pancreatic cancer, that allowed him to come to think that he might be able to reverse his cancer with diet plus various “alternative” modalities.

In the immediate aftermath of Steve Jobs’ death, I summarized the facts about Jobs’ case that were known at the time. In particular, I took issue with the claims of a skeptic that “alternative medicine killed Steve Jobs.” At the time, I pointed out that, although it was very clear that Steve Jobs did himself no favors by delaying his initial surgery for nine months after his initial diagnosis, we do not have sufficient information to know what his clinical situation was and therefore how much, if at all, he decreased his odds of survival by not undergoing surgery expeditiously. To recap: Did Steve Jobs harm himself by trying diet and alternative medicine first? Quite possibly. Did alternative medicine kill him? As I’ve argued before, that’s impossible to say, and any skeptic who dogmatically makes such an argument has taken what we known beyond what can be supported. Regular readers know that when I see a story that looks as though “alternative medicine” directly contributed to the death of someone, I usually pull no punches, but in this case I had a hard time being so definitive because the unknowns are too many, with all due respect to Ramzi Amri, a Research Associate at Harvard Medical School who in my opinion also went too far. I did, however, point out that I’m always open to changing my opinion if new evidence comes in. Jobs was always incredibly secretive about his medical condition, so much so that it didn’t even come out in the press until after it had happened that he had undergone a liver transplant in 2008 for metastatic insulinoma in his liver, just as his cancer diagnosis in 2003 remained secret for 9 months, not being revealed until he sent an e-mail to Apple employees announcing that he had undergone surgery.

It turns out that, with the imminent release of a major biography of Steve Jobs, more information is finally trickling out about his medical history. For instance, Jobs’ biographer Walter Isaacson is going to appear on 60 Minutes this Sunday, and apparently he is going to say this:

Steve Jobs’ cancer and pushing the limits of science-based medicine

Editor’s note: There is an update to this post.

An Apple fanboy contemplates computers and mortality

I’m a bit of an Apple fanboy and admit it freely. My history with Apple products goes way back to the early 1980s, when one of my housemates at college had an Apple IIe, which I would sometimes use for writing, gaming, and various other applications. Indeed, I remember one of the first “bloody” battle games for the IIe. It was called The Bilestoad and involved either taking on the computer or another opponent with battle axes in combat that basically involved hacking each other’s limbs off, complete with chunky, low-resolution blood and gore. (You youngsters out there will be highly amused at the gameplay here.) Of course, it’s amazing that nothing’s changed when it comes to computer games except the quality of graphics. Be that as it may, this same roommate was one of the first students to get a hold of the new Macintosh when it was released in early 1984. I really liked it right from the start but only got to play with it occasionally for a few months. After using a Macintosh SE to do a research project during my last year of medical school, I have used the Macintosh platform more or less exclusively, and the first computer I purchased with my own money was a Mac LC back in 1990 or 1991. Today, I have multiple Apple products, including my MacBook Air, my iPhone, and my old school iPod Classic, among others. Oddly enough, I do not have an iPad, but that’s probably only a matter of time, awaiting software that lets me do actual work on it.

All of this is my typical long-winded way of explaining why I was immensely saddened when I learned of Steve Jobs’ death last week. Ever since speculation started to swirl about his health back 2004 and then again in 2008, capped off by the revelation that he had undergone a liver transplant for a rare form of pancreatic cancer in 2009, I feared the worst. Last week, the end finally came. However, there is much to learn relevant to the themes of this blog in examining the strange and unusual case of Steve Jobs. Now, after his death five days ago, which coincidentally came a mere day after the launch of iCloud and the iPhone 4S, it occurs to me that it would be worthwhile to try to synthesize what we know about Jobs’ battle with cancer and then to discuss the use (and misuse) of his story. Of course, this is a difficult thing to do because Jobs was notoriously secretive and I can only rely on what has been published in the media, some of which is conflicting and all of which lacks sufficient detail to come to any definite conclusions, but I will try, hoping that the upcoming release of his biography by Walter Isaacson in couple of weeks might answer some of the questions I still have remaining, given that Isaacson followed Jobs through his battle with cancer and was given unprecedented access to Jobs and those close to him.

In the meantime, I speculate. I hope my speculations are sufficiently educated as not to be shown to be completely wrong, but they are speculations nonetheless.

Scientific American Mind Is Not So Scientific

When Scientific American first announced that they would publish Scientific American Mind, I hurried to subscribe, thinking it would keep me informed about new developments in a field I am passionately interested in. I have enjoyed the magazine, particularly the regular columns, the news items about research findings, the reviews that alert me to books I will want to read, the “Ask the Brains” Q and A, the challenging “Head Games” quiz, and the presentation of many intriguing ideas. The board of advisers is impressive, and the columns by Christof Koch, Scott Lilienfeld, Hal Arkowitz, the Ramachandrans and others have been consistently excellent. Unfortunately, some of the other articles have descended into pop psychology, speculation, poor science and even pseudoscience. Contributing editor Robert Epstein’s articles have particularly raised my blood pressure.

Love-Building Exercises

In December 2009 I was annoyed enough to write this letter to the editor:

After reading Robert Epstein’s article in the last issue, I had to go back to the cover and verify that the word “scientific” was indeed part of the title of your magazine. The Love Building Exercises he recommends are more appropriate to a magazine of fantasy and science fiction.

Two as One — feeling that the two of you have merged?
Soul Gazing — looking into the very core of your beings?
A Mind-Reading Game — wordlessly trying to broadcast a thought to another person?
Love Aura — feeling “eerie kinds of sparks” when your palm is close to another’s?

Thought transfer? Auras? Come on! Shame on you for publishing such metaphysical pseudoscientific psychobabble!

They published my letter to the editor with the heading “Hating ‘Love’.” There was no response from the author.

Survey says, “Hop on the bandwagon of ‘integrative medicine’!”

A Brief Clinical Vignette

In researching this post, I found an article published nearly two years ago in The Hospitalist entitled Growth Spurt: Complementary and alternative medicine use doubles, which began with this anecdote:

Despite intravenous medication, a young boy in status epilepticus had the pediatric ICU team at the University of Wisconsin School of Medicine and Public Health in Madison stumped. The team called for a consult with the Integrative Medicine Program, which works with licensed acupuncturists and has been affiliated with the department of family medicine since 2001. Acupuncture’s efficacy in this setting has not been validated, but it has been shown to ease chemotherapy-induced nausea and vomiting, as well as radiation-induced xerostomia.

Following several treatments by a licensed acupuncturist and continued conventional care, the boy’s seizures subsided and he was transitioned to the medical floor. Did the acupuncture contribute to bringing the seizures under control? “I can’t say that it was the acupuncture — it was probably a function of all the therapies working together,” says David P. Rakel, MD, assistant professor and director of UW’s Integrative Medicine Program.

The UW case illustrates both current trends and the constant conundrum that surrounds hospital-based complementary medicine: Complementary and alternative medicine’s use is increasing in some U.S. hospitals, yet the existing research evidence for the efficacy of its multiple modalities is decidedly mixed.

My jaw dropped in horror when I read this story. Acupuncture for status epilepticus? There’s no evidence that it works and no scientific plausibility suggesting that it might work. And what does the questionable research suggesting that acupuncture might ease chemotherapy-induced nausea and vomiting or radiation-induced xerostomia (which, if you look more closely at the studies, it almost certainly does not, but that’s a post for another time) have to do with this case, anyway? Nothing. Worse, Dr. Rakel fell for the classic post hoc ergo propter hoc fallacy; i.e., despite his disclaimer, he appears to be implying that, because the child recovered, acupuncture must have contributed to his recovery. He also repeats the classic fallacy that I’ve written about time and time again in the context of cancer therapy, namely that if a patient is using quackery as well as science-based medicine, then either it was the quackery that cured him or the quackery somehow made the conventional medical care work better.

I expect better from an academic medical center like the University of Wisconsin. Unfortunately, increasingly I’m not getting it. Quackademic medicine is infiltrating such medical centers like kudzu.

TIME Magazine, Dr. Oz, What to Eat, and Supplements

Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead and pretend to heal people with carnival sideshow tricks. We tend to be negative and critical because somebody has to do it, but it’s not pleasant.  For once, I have some good things to say.

The September 12 issue of TIME magazine was a Special Nutrition Issue. The cover featured pictures of food and the title “What to Eat Now: Uncovering the Myths about Food by Dr. Oz.” It devotes 7 pages to an article by him entitled “The Oz Diet: No more myths. No more fads. What you should eat — and why.” This is followed by a 5 page article by John Cloud “Nutrition in a Pill? I took 3000 supplements over five months. Here’s what happened.” Both articles have a rational, science-based perspective without any intrusions of woo-woo. (more…)

Gullible George

I get the occasional email.  Very little hate mail, unfortunately, since hate mail is often more amusing.  I read what little email I receive, and usually do not respond, mostly as I do not have the time.  I am a slow writer and a slower typist, and there are just so many hours in the day, and the older you get, the shorter th0se hours become.

Recently, over at the center of the growing Mark Crislip multimedia empire, I had the following in the feedback section:

Just thought you’d like to know:

My kids watch the PBS show “Curious George” which usually does a good job with introductory Physics, Astronomy, scientific method, etc. Interspersed with the cartoons they have scenes with real children that do a real-life parallel investigation of what happened on Curious George.

Today’s episode involved the Man with the Yellow Hat catching a cold, and Curious George going to the pharmacy and picking up various drugs to assist in making the guy feel better, mainly to have him sleep and be comfortable.

The interspersed skit, however, had the children visit a naturopath, where they learned:
* Oregano cures infections
* Various pressure points that correspond to energy lines
* And that taping magnets to these points is really effective.

I sat here simply amazed.

Me, not so much.  Alternative medicine has always been a blind spot for PBS.  While PBS  would not show perpetual motion machines,  suggest that astrology is legitimate, or give credence to a flat earth, alternative medicine, as it is for many otherwise thoughtful people, is exempt from even cursory critical thinking. PBS has broadcast  Drs. Chopra and North, so its track record with science based medicine is not so good. My children are long past the Curious George part of their lives, but I read them the books when they were kids.  Not my favorite (I like the Madeleine books better; 6 weeks in hospital for an acute appendix never failed to amuse me) but they were a quick read when the kids wanted a story at bedtime and I was too tired for a longer exposition.

Dummy Medicine, Dummy Doctors, and a Dummy Degree, Part 2.0: Harvard Medical School and the Curious Case of Ted Kaptchuk, OMD

Review

The recent albuterol vs. placebo trial reported in the New England Journal of Medicine (NEJM) found that experimental subjects with asthma experienced substantial, measured improvements in lung function after inhaling albuterol, but not after inhaling placebo, undergoing sham acupuncture, or “no treatment.” It also found that the same subjects reported having felt substantially improved after either albuterol or each of the two sham treatments, but not after “no treatment.” Anthropologist Daniel Moerman, in an accompanying editorial, wrote, “the authors conclude that the patient reports were ‘unreliable,’ since they reported improvement when there was none”—precisely as any rational clinician or biomedical scientist would have concluded.

In Part 1 of this blog we saw that Moerman took issue with that conclusion. He argued, with just a bit of hedging, that the subjects’ perceptions of improvement were more important than objective measures of their lung function. I wondered how the NEJM editors had chosen someone whose bibliography predicted such an anti-medical opinion. I doubted that Editor-in-Chief Jeffrey Drazen, an expert in the pathophysiology of asthma, had ever heard of Moerman. I suggested, in a way that probably appeared facetious, that Ted Kaptchuk, the senior author of the asthma report, might have recommended him. (more…)

“Integrative medicine”: A brand, not a specialty

Author’s note: This post was inspired in part by a post by Wally Sampson entitled Why would medical schools associate with quackery? Or, How we did it.

PRELUDE

Once upon a time, there was quackery.

Long ago, back in the mists of time before many of our current readers were even born and far back in the memory of even our wizened elders of medicine, “quackery” was the preferred term used to refer to ineffective and potentially harmful medical practices not supported by evidence. Physicians, having a grounding in science and prior plausibility, for the most part understood that modalities such as homeopathy, reflexology, and various “energy healing” (i.e., faith healing) methodologies were based either on prescientific vitalism, magical thinking, and/or science that was at best incorrect or at the very least grossly distorted. More importantly, physicians weren’t afraid to call quackery quackery, quacks quacks, and charlatans charlatans.

Not surprisingly, quacks and charlatans did not like this.

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.

Revisiting Daniel Moerman and “placebo effects”

About three weeks ago, ironically enough, right around the time of TAM 9, the New England Journal of Medicine (NEJM) inadvertently provided us in the form of a new study on asthma and placebo effects not only material for our discussion panel on placebo effects but material for multiple posts, including one by me, one by Kimball Atwood, and one by Peter Lipson, the latter two of whom tried to point out that the sorts of uses of these results could result in patients dying. Meanwhile, Mark Crislip, in his ever-inimitable fashion, discussed the study as well, using it to liken complementary and alternative medicine (CAM) as the “beer goggles of medicine,” a line I totally plan on stealing. The study itself, we all agreed, was actually pretty well done. What it showed is that in asthma a patient’s subjective assessment of how well he’s doing is a poor guide to how well his lungs are actually doing from an objective, functional standpoint. For the most part, the authors came to this conclusion as well, although their hedging and hawing over their results made almost palpable their disappointment that their chosen placebos utterly failed to produce anything resembling an objective response improving lung function as measured by changes (or lack thereof) in FEV1.

In actuality, where most of our criticism landed, and landed hard—deservedly, in my opinion—was on the accompanying editorial, written by Dr. Daniel Moerman, an emeritus professor of anthropology at the University of Michigan-Dearborn. There was a time when I thought that anthropologists might have a lot to tell us about how we practice medicine, and maybe they actually do. Unfortunately, my opinion in this matter has been considerably soured by much of what I’ve read when anthropologists try to dabble in medicine. Recently, I became aware that Moerman appeared on the Clinical Conversations podcast around the time his editorial was published, and, even though the podcast is less than 18 minutes long, Moerman’s appearance in the podcast provides a rich vein of material to mine regarding what, exactly, placebo effects are or are not, not to mention evidence that Dr. Moerman appears to like to make like Humpty-Dumpty in this passage:
