Science vs Homeopathic Pseudoscience

Science is a philosophy, a technology, and an institution. It is a human endeavor- our collective attempt to understand the world around us,  not something that exists solely in the abstract. All of these aspects of science have be progressing over the past decades and centuries, as we refine our concepts of what science is and how it works, as we develop...

EMDR and Acupuncture – Selling Non-specific Effects

The scientific approach to understanding the world includes the process of carefully separating out variables and effects. Experiments, in fact, are designed specifically to control for variables. This can be especially challenging in medicine, since the body is a complex and variable system and there are always numerous factors at play. We often characterize the many variables that can influence the outcome...

CAM and Evidenced-Based Medicine

Mark Tonelli, MD has problems with evidence-based medicine (EBM). He has published a few articles detailing his issues, and he makes some legitimate points. We at science-based medicine (SBM) have a few issues with the execution of EBM as well, so I am sympathetic to constructive criticism. In an article titled: Integrating evidence into clinical practice: an alternative to evidence-based approaches. The...

Help – My Doctor is a Crank!

I often receive e-mail from SBM readers (or SGU listeners) who have had the experience of their doctor, nurse, dentist, physical therapist, or other health care provider recommending to them a treatment option that seems dubious, if not outright pseudoscientific. They want advice on what to do.  There are common themes to the e-mails – the writer often feels very uncomfortable in...

The Dark Side of Medical Globalization

You are not going to change what we do, you’re not going to change our determination to make these patients better. I see these patients, I know these patients, I value these patients, I’ve looked after them for years. I’ve seen them after the procedure, the vast majority are improved. The above quote could be a reference to just about any fringe...

Yes, it's true that placebos are just as powerful as homeopathy. Unfortunately, that doesn't mean what believers in integrative medicine think it does.

Placebo Effect for Pain

It has long been recognized that there are substantial multifactorial placebo effects that create real and illusory improvements in response to even an inactive treatment. There is a tendency, however (especially in popular discussion), to oversimplify placebo effects – to treat them as one mind-over-matter effect for all outcomes. Meanwhile researchers are elucidating the many mechanisms that go into measured placebo effects,...

The Hidden Cancer Cure

Last week David Gorski wrote a excellent post about why we have not yet cured cancer. It turns out, cancer is a category of many individual diseases that are very challenging to treat. We have made steady progress, and many people with cancer can now be cured – but we have not discovered the one cure for all cancer. I personally am...

Treating The Common Cold

For the last week I have had a cold. I usually get one each winter. I have two kids in school and they bring home a lot of viruses. I also work in a hospital, which tends (for some reason) to have lots of sick people. Although this year I think I caught my cold while traveling.  I’m almost over it now,...

One weird trick to avoid the 'flu.

The Flu Vaccine and Narcolepsy

Preliminary evidence has linked the flu vaccine to narcolepsy in several Scandinavian countries. Is the link real? What could be the mechanism?

The Safety Checklist

During my recent stint covering the Neuro ICU I noticed for the first time a checklist posted above each patient bed. The checklist covered the steps to undergo whenever performing an invasive procedure on the patient. I was glad to see that the checklist phenomenon had penetrated my hospital, although the implementation of safety checklists is far from complete. A recent study...
