Dr Art Hister – Laptopitis

If you don’t already have enough to worry about, and if like me, you spend lots of time at a computer, then here’s yet another new “condition” to be wary of, according to a group of researchers at the University of North Carolina (Chapel Hill).

They call it “laptopitis” and no, they aren’t referring to infections you can pick up from sharing a computer with people who left viral and bacterial particles behind when they used the keyboard that you are now using (although that does happen lots, I’m sure).

Rather, “laptopitis” is the name these people coined for all the aches and pains – chronic headaches, neck and shoulder pain, low-back pain, wrist pain, and so on – that a person can develop from either over-using a computer, that is, from endless hours of sitting at a terminal without getting up, or more likely, from using poor posture and improper techniques when using a computer.

So, if you want to prevent “laptopitis” or if you already have some elements of it and you want to make sure it doesn’t get worse, do yourself a favour and visit one of the host of web sites that give you all sorts of tips about what’s best to do when working at a computer – what height it’s best to set the monitor at, how to rest your arms, what kind of chair to use, etc. – although the tip that I want to emphasize is the one I think most people ignore the most: get up often from your seated position.

Sitting for several hours in a row is just not conducive to good health, either good physical health, or equally important, good psychological health.

And when you get up from your desk, here’s another important tip if you want to stay healthy: don’t automatically go to the fridge.

Dr Art Hister – Don’t Do Drugs and Drive

A couple of disturbing studies from the Canadian Centre on Substance Abuse have determined that among drivers, drug use is quickly approaching (and may even have surpassed) alcohol as a major danger.

In one study from BC, random testing revealed that alcohol was found among 8 % of drivers, but drugs were detected in 10 % of drivers.

In a 2nd study that examined fatalities among drivers, alcohol played a role in 38 % of such deaths, while at least one kind of drug was detected in 33 % of motor vehicle drivers who died between 2000 and 2006 (I would guess that that rate is probably higher in 2010 since the use of all drugs, not just recreational drugs, has gone up quite substantially in the last decade).

A few things should be glaringly obvious from these reports.

First, lest we forget, despite the glaring headlines about drug use in drivers, these studies confirm that alcohol use is still a huge, huge problem for drivers and at least as dangerous as drugs.

That said, for all those who argue that marijuana use has no substantial health consequences, well, yes, it can and too often, it does: marijuana use poses a big risk not only to the marijuana user who smokes and then drives, but it also poses a huge risk to the other drivers and pedestrians and cyclists that user might encounter when he’s high and his reflexes and awareness are not what they should be.

Third, and equally important, lots of prescription and some over-the-counter drugs can also affect neurological and brain functioning so if you’re taking such medications, it would be best to avoid driving until you knew precisely what effect those drugs have on your reflexes and awareness.

Dr. Art Hister – High Blood Pressure Pills

You might want to label the latest good news about high blood pressure (HBP) pills, ‘Hats Off to ALLHAT’.

You see, these days every study gets a fancy name with an acronym attached (CREST, MRFIT, and so on) in order to make the results of the study more memorable for everyone (hey, doctors are no different than you are: we also forget lots of stuff unless we have mnemonic devices to help us), and of the thousands of HBP studies that have been done, the most famous one without doubt is ALLHAT because if your doctor is in the least bit interested in blood pressure, there’s a very good chance he or she will know what the ALLHAT study concluded, and all the controversy that conclusion came to.

Thus, when the first ALLHAT results were announced, the conclusion was pretty simple: in a 3-way race of HBP pills that compared an old, pretty cheap but tried-and-true generic diuretic (the kind of blood pressure pill that doctors have been using for decades) to two new HBP drugs, a calcium channel blocker and an ACE inhibitor, the researchers concluded that the diuretic was the best drug. Period.

Many experts, however, refused to accept those ALLHAT conclusions, arguing that if the study had just gone on a few years more, it’s likely that the newer (and much more expensive drugs) would edge out the diuretic at lowering the rate of complications (strokes, kidney damage, heart attacks, etc.) from high blood pressure.

So guess what?

An update on ALLHAT has just been released at a major conference in China, and while the edge for the diuretic has narrowed somewhat, after 8-13 years, the best you can say about the other drugs is that they are no better than the diuretic at lowering complications from HBP (in fact, there is some room to argue that the new drugs are somewhat worse since one of them led to a higher risk of strokes in this study, while the other produced a higher risk of heart failure).

Now, this doesn’t mean that a person taking an ACE inhibitor or a calcium channel blocker should instantly stop their drug and start on a diuretic but it certainly implies that anyone on one of these pills might want to at least talk to their doctor about whether they should continue with those meds.

Heart-Healthy Living – Part 2

In the past, heart disease was a greater problem for men than it was for women, but today heart disease and stroke take the lives of nearly as many women as men. And while most of the risk factors for heart disease are the same for both sexes, women’s hearts are affected by some special factors that don’t apply to men.
