The stem cell hard sell returns.

The stem cell hard sell, Stemedica edition

I first became more interested in dubious stem cell clinics nearly two years ago, when I learned that hockey legend Gordie Howe was undergoing stem cell therapy in Mexico to treat his stroke. Prominent in stories about Howe were two companies: Stemedica Cell Technologies, a San Diego company marketing stem cell treatments for all manner of ailments, and Novastem a partner company...

Carotid Artery Stenosis: Surgery, Stent, or Nonsurgical Stroke Prevention?

The carotid artery in the neck is a common site of atherosclerosis. As plaque builds up, it leaves less room for blood flow and can cause strokes through clotting or embolization. Carotid stenosis is defined as a greater than 70% narrowing of the lumen (the space through which the blood flows in an artery). It can cause symptoms, including transient ischemic attacks...

Did chiropractic neck manipulation kill Katie May?

Well, we’re back. Yes, after having our WordPress database somehow borked to the point where no new posts could be added and no existing posts could be edited since Friday, Science-Based Medicine is back in business—finally! As a result, some of you might have seen this post elsewhere, as it was considered to be somewhat time-sensitive, and I didn’t want to delay,...

Stem cells versus Gordie Howe’s stroke, part 3

Here I am in Philadelphia attending the 2015 American Association for Cancer Research (AACR) meeting to imbibe the latest basic and translational science about oncology. So what am I doing in my non-conference time? I’m holed up in my hotel room near Rittenhouse Square writing a DoD Grant and this post. Fortunately, I am nearly done with the grant, with nothing I...

An aboriginal girl dies of leukemia: Parental “rights” versus the right of a child to medical care

One topic that keeps recurring and obligating me to write about it consists of critically analyzing stories of children with cancer whose parents, either on their own or at the behest of their child, stop or refuse chemotherapy or other treatment. It is, sadly, a topic that I’ve been discussing for nearly a decade now, starting first on my not-so-super-secret other blog...

Stem cells versus Gordie Howe’s stroke, part 2

Another Christmas has come and gone, surprisingly fast, as always. I had thought that it might make a good “last of 2014” post—well, last of 2014 for me, anyway; Harriet and Steve, at least, will be posting before 2014 ends—to do an end of year list of the best and worst of the year. Unfortunately, there remains a pressing issue that doesn’t...

Stem cells versus Gordie Howe’s stroke

Note: There is now a major update to this story published here, which explains a lot of the questions remaining in this blog post. Seven years ago I returned to Michigan, where I was born and spent the first quarter century of my life, after an absence of more than 20 years. In the interim, I had done my surgical residency and...

Low Dose Aspirin for Primary Prevention

A new study published in JAMA sheds further light on a controversial question – whether or not to prescribe low-dose aspirin (81-100mg) for the primary prevention of vascular disease (strokes and heart attacks). Primary prevention means preventing a negative medical outcome prior to the onset of disease, in this case preventing the first heart attack or stroke. Secondary prevention refers to treatments...

Stroke Death from Chiropractic Neck Manipulation

Case reports are perhaps the weakest form of medical evidence. They are essentially well-documented anecdotes. They do serve a useful purpose, however: they can illuminate possible correlations, the natural course of illness and treatment, and serve as cautionary tales regarding possible mistakes, risks and complications. I say “possible” because they are useful mainly for generating hypotheses and not testing or confirming hypotheses....

Neuro-Acupuncture and Stroke

On the home page of Zhu’s Neuro-Acupuncture Center there is a video relaying a testimonial of how scalp acupuncture helped a patient recover from acute stroke. The use of testimonials is very common in the promotion of dubious health treatments. A personal story and endorsement is psychologically more compelling than dry data. Testimonials are completely unreliable, however, and in fact I would...
