The American population is obsessed with germs. Although relatively few people are unfortunate enough to suffer from OCD, a more pervasive subclinical paranoia persists in our psyche which manifests as our culture of cleanliness. During daytime television it is almost impossible to go through an entire commercial break without seeing an ad for cleaning products such as soaps, air sanitizers, detergents, or other various cleaning paraphernalia. Additionally, more and more of these products are emerging with some form of antimicrobial, antibacterial, or bacteriostatic chemical included to “stay tough on germs.” One such example is the chemical triclosan, although there are several others with similar issues.

It has been known for years that babies in utero (womb) suffer ill effects from their mothers’ exposure to tobacco, drugs and alcohol. A new study funded by the National Institute on Drug Abuse and performed by Michael Rivkin of Children’s Hospital Boston showed that children exposed to these toxins may suffer effects well into early adolescence.

Using MRI technology, the study looked into the long term effects of prenatal exposure to drugs, alcohol, tobacco or a combination of the three on the brain structure of preteens. The study found that these kids have thinner cortical grey matter than subjects who did not suffer exposure to toxins in utero. This study also showed a reduction in brain volume directly tied to this exposure. Read more →

Multiple sclerosis (MS) is a poorly understood disease that affects patients at an early age and, usually, lasts a lifetime. Factors that predispose to the development of MS include genetics, geographic location, sex and birth month, suggesting an interesting nature-nurture interaction in this disease process.

The increased rate of MS at high latitudes has been demonstrated in many studies, with those living in the Northern United States and Canada at a higher risk than those closer to the equator. This geographical influence is most commonly linked to the decreased (UV) radiation in these locations. UV light is a requirement for the production of vitamin D, and it is this effect that is most commonly thought to increase the risk of MS. Read more →
