One of the basic human “needs” is the desire for simplicity. We have limited cognitive resources, and when we feel overwhelmed by complexity one adaptive strategy is to simplify things in our mind. This can be useful as long as we know we are oversimplifying. Problems arise when we mistake our schematic version with reality.
In this same vein we also like our narratives to be morally simple, so there is a tendency to replace the complex shades of gray with black and white. This is perhaps related to cognitive dissonance theory. We have a hard time reconciling how someone can be both good and bad, or how a good person can do bad things. So there is also a tendency to see people as all good or all bad. We can transcend these tendencies with maturity and wisdom, but that takes work.
A good example of the desire for simple moral clarity is the anti-vaccine movement. Their world is comprised of white hats and black hats (guess which one they perceive themselves as wearing), as evidenced by the blog posts and comments over at Age of Autism. There is a certain demand for purity of thought and message that seems to be getting worse over time in a self-reinforcing subculture. Many now see their struggle in apocalyptic terms.
The desire for simplicity even extends to factual claims. Read more »

Yesterday’s post was not really about Avastin, but about medical journalism and how patients’ voices are handled by the media.
L. Husten, writing on a Forbes blog, cried that the press fawned, inappropriately, over patients’ words at the FDA hearing last week, and that led him to wonder why and if journalists should pay attention to what people with illness have to say, even if their words go against the prevailing medical wisdom.
There’s a fair amount of controversy on this. For sake of better discussion in the future, I think it best to break it up into 3 distinct but inter-related issues:
1. About health care journalism and patients’ voices:
A general problem I perceive (and part of why I started blogging) is how traditional medical journalists use patients’ stories to make a point. What some of my journalism professors tried to teach me, and most editors I’ve dealt with clearly want, is for the reporter to find a person with an illness, as a lead, and then tell about the relevant news, and provide some expert commentary – with at least one person speaking on each “side” of the issue, of course – and then end the story with some bit about the patient and the future.
I argue that this form of medical journalism Read more »

Both Germany and France have now suspended the marketing of Actos (pioglitazone) due to concerns of a link between Actos and bladder cancer. Though we have known about bladder cancer concerns for some time, these recent concerns about the bladder cancer link stem from a recent report analyzing the FDA’s Adverse Event Reporting System (AERS), which found that 93 cases of cancer were recorded between 2004 and 2009 in patients treated with antidiabetic drugs, of which 31 patients were treated with pioglitazone, representing a statistically significant increased risk of bladder cancer (ROR 4.30, 95% confidence interval, 2.82-6.52; P less than 0.0001).
Interestingly, the FDA announced that it was going to look into the link between Actos and bladder cancer only a few days before it made its final decision on what to do with Avandia (as if they didn’t know about the Actos cancer risk before the July 2010 advisory board).
Despite the many things you have heard about Avandia, back in July 2010, the FDA decided to severely restrict the use of Avandia for three reasons: Read more »

Every once in a while, a press release comes along that’s worth mocking publically. Here’s one of them.
In honor of National Mental Health Month, one PR flack pitched Philip Stein watches. In the flack’s words: “The highlighted element of the watch is the brand’s exclusive wellness technology that helps wearers improve sleep and reduce stress. The watch is embedded with a metal disk that emits natural frequencies into the body wearer and in turn, affects the wearer’s energy field. It’s called ‘Natural Frequency Technology’ and is a new patented technology studies suggest help to improve sleep quality and reduces stress.”
Really. That’s what the flack said. Right off the bat, he’s gone from mental health issues to sleepless nights from stress. Not content with confounding the two issues, he continues: “Dr. Jeff Gardere, America’s well-known psychologist, is Chief Medical Executive for Philip Stein Watches and had been running a practice for over 20 years. He recognized during that time that there was a huge need to educate the public on the possible severities of stress and everyday lifestyle changes that everyday people can make without a prescription. Dr. Gardere found a natural way to reduce stress and prescribed his patients with a high-end accessory Philip Stein Watch.”
The psychologist “prescribed” a watch. I wonder if my insurance company would pay for that scrip? Read more »

I recently stumbled upon a very interesting editorial opinion in the ‘European Journal of Clinical Pharmacology’: ‘The use of drugs is not as rational as we believe…but it can’t be! The emotional roots of prescribing’, authored by Albert Figueras, from Fundació Institut Català de Farmacologia (Catalonia Institute of Pharmacology Foundation at Vall d’Hebron Hospital, in Barcelona).
Since more than 40 years ago when Archie Cochrane said that “there must be solid scientific evidence behind any statement, decision and prescription made by medical staff”, and all the way until today’s WHO promotion of rational medicine utilization, both developing and industrialised countries have been striving to increase sound knowledge about prescription and thus spread the kind of rational thinking necessary to foster evidence-based medicine in drug use.
Keeping your skills up to date has never been an easy task but nowadays we have newsletters and other Internet tools that can grant any MD state-of-the-art knowledge on any subject he or she may need, accessible anywhere and for any medical speciality. Nevertheless, drug use in the “real world” is far from this high quality. Not only in Spain: it has been noted in France, Greece and other countries that, despite widespread knowledge of risk factors that may cause gastrointestinal toxicity in patients under nonsteroidal anti-inflammatory drugs (NSAID) treatment, there is a massive use of proton-pump inhibitors in individuals that show no significant risk.
Changing well-established drugs for newer, less-known products is not consistent with the need of a well-grounded comparative evaluation. We are not raising concern on the influence of gifts or invitations from pharmaceutical companies. Many doctors really want to make rational decisions… but can’t. Read more »
