National Health Interview Survey 2007 – CAM Use by Adults

The Center for Disease Control (CDC) conducts an ongoing telephone survey of medical problems and health care utilization – called the National Health Interview Survey (NHIS). They recently released their data from 2007. This is the first year for which they specifically broke out questions assessing the use of so-called complementary and alternative medicine (CAM).

The Importance and Limitations of Peer-Review

Peer-review is a critical part of the functioning of the scientific community, of quality control, and the self corrective nature of science. But it is no panacea. It is helpful to understand what it is, and what it isn’t, its uses and abuses. Overview When the statement is made that research is “peer-reviewed” this is usually meant to refer to the fact...

Attitudes and Public Health

Increasingly there is a cultural trend toward health care freedom and empowerment. This trend is partly a reaction to the paternalism of the past, and reflects an overall change in attitude by the public toward all institutions and authority. Within medicine there has also been a move toward the partnership model of practice – where patients are well-informed full partners in the...

Recognizing Dubious Health Devices

The public is often left to fend for themselves in the marketplace of medical devices and health aids. Current regulations in most countries are inadequate to prevent grossly misleading claims in advertising and to provide adequate evidence for safety and effectiveness for products on the market. So it is helpful for consumers to be aware of the red flags for dubious devices...

Pro-CAM Wikipedia – Skeptics Need Not Apply

The internet is arguably the ultimate expression of democracy and the free market. For the cost of internet access anyone can pull up a virtual soap box and preach to the world. There are no real gatekeepers, and the public can vote with their search entries, clicks, and links. Every point of view can be catered to and every special interest satisfied....

Calories In – Calories Out

There is general agreement that the US, and the West in general, is in the midst of an obesity epidemic. Even if you think this is alarmist or overstating the situation, the data clearly shows a steady expansion of the American waistline. Weight loss is a multi-billion dollar industry and is an active area of research, and yet all the self-help books,...

HIV Treatment Extends Life Expectancy

People with HIV are living longer on the latest anti-retroviral therapy. This is something any infectious disease specialist knows from their own clinical experience – but it’s reassuring (I would even argue necessary) to have objective data to support experience. A study published in the latest issue of Lancet provides this objective data. (Lancet. 2008 Jul 26;372(9635):293-9.) The press release from Bristol...

Autism and Vaccines: Responding to Poling and Kirby

In response to my NeuroLogica blog post on Monday, David Kirby wrote a response in the Huffington Post and Dr. Jon Poling (father of Hannah Poling) wrote an open letter to me, placed in the comment section and posted at Age of Autism. It seems only polite that I respond to their kind attention.The primary focus of my original post (which I...

A Guide for Confronting Patients

I sometimes lecture on science-based medicine to my colleagues and one of the most common questions I get is how to deal with a patient who expresses belief in unscientific treatments. The dilemma for the physician is that professionalism requires that we do not confront patients regarding their personal beliefs. We are there to inform and advise, not preach. And yet proper...
