Antibiotic resistance is a problem that we have been aware of almost since penicillin was first developed. Its the natural outcome of natural selection when bacteria are exposed to antibiotics, but now we are facing a moment when resistance may disarm even our newest and best antibiotics leaving us vulnerable to infections once again.

Proteins are the most important molecules in our bodies. Proteins are the building blocks of every structure in your body. Specialised proteins form everything from enzymes, to hormones, receptors, and antibodies. The unique properties of proteins allow them to be formed into an almost infinite number of shapes allowing them to accomplish so many important tasks.

The flu season will be here soon and getting vaccinated is the best way to protect yourself from this serious illness, but influenza is not the only contagious disease that adults need to protect themselves from. Vaccines aren't just for children. Some illnesses require updated vaccines from time to time and other diseases are more common only in adulthood.

Genetically Modified Oragnisms (GMO's) have been in the news the past few years as activists in the U.S. and Europe have mounted a campaign to rid our diets of foods that have been altered using the new techniques of genetic engineering. Recently they have pushed for legislation to require labeling of all foods that contain GMO's
Opponents of GMO products believe that all foods should be labelled "GMO free"  or "Contains GMO's" so consumers will know what they are buying. They believe its only logical and right to provide consumers with more information so that they can make informed decisions. The problem with this approach is that more information is really only useful when it makes us more knowledgeable. If the information in fact misinforms us then it is worse than no information at all. Labelling products that contain GMO's creates the false impression among consumers that these products may be less safe than products which don't contain them, otherwise why would the government require such labeling? But if you look at the facts, there is no evidence that GMO's are less safe than other foods and in most ways they are no different than the foods we have all been eating for centuries.

Not too long ago I met a new patient who had come to me after her previous doctor had retired.  She was a very pleasant older woman who was retired herself and on a fixed income. She was relatively healthy but had a number of chronic medical conditions such as high blood pressure, high cholesterol, diabetes and an underactive thyroid that were well controlled with the use of six different medications which she took daily. During the visit she related that she did not always take her medications because the cost had gotten so high, amounting to more than $600 a month.

The brain is the most complex structure known to man. There are almost 100 billion nerve cells in the brain, each with up to a thousand connections to other nerve cells. That means there are over a trillion connections in the human brain.

The summer is a time of increasing outdoor activities and with that comes an increased chance of exposure to insects and in particular ticks. While its possible to be bitten by ticks even in the depths of winter boths ticks and people are more active in the warmer months. This means the summer is a time when they are more likely to come into contact with each other so this is a good time to go over some of the illnesses that ticks carry. Its also an opportunity to dispell some of the myths and discuss a few precautions we can take to stay healthy when we are enjoying the outdoors.
