Medical science is getting closer to understanding one of the most common causes of chronically itchy arms called brachioradial pruritus.
This means we’re also getting closer to helping people who suffer from this extremely frustrating condition!
A new study exploring the cause of brachioradial pruritus was just reported in the October issue of the Journal of the American Academy of Dermatology. The authors used MRI imaging to look at the cervical spine of 41 patients suffering from chronic itching of what was otherwise normal appearing skin on the outer surface of their forearms arms (called brachioradial pruritus). MRI imaging showed a very strong correlation between the itch and nerve compression in the patient’s neck. In fact, the exact site of the itch on the skin correlated precisely with the spinal location in the neck where the nerve resides that supplies that part of the arm skin (we call this a dermatome*).
What’s so interesting is that Read more »

Reader Question:
Do you do anti-aging medicine? I do not see it on your web site. If not, what is your opinion of it?
I am not a fan or follower of the anti-aging medicine fad in so much that it promotes what I believe to be a false concept. An older person cannot be made into a younger version of herself by boosting certain hormones. There is really no good evidence that it works. Patients don’t live any longer. It might also be found to be harmful in the long run.
Plastic surgeons will differ in their opinions as to what works with low risk to improve things. To me Read more »

Baby skin is sun-sensitive.
Everyone wishes they had baby skin. It feels so soft and smooth; it’s perfectly adapted to induce us adults to want to clean their diaper, no matter how many times they dirty them. Like their big eyes and cute noses, baby skin is part of the whole package of being adorable. But like their eyes, their skin, however beautiful, is immature. Baby skin is thinner, has less natural moisturizers and has fewer pigment cells, making it more vulnerable to the environment than adult skin.
This is important especially in summer. How often do you see babies running around on the beach with just a diaper on? Although they seem indestructable, they are more vulnerable than the adult holding the pail and shovel.
Studies have shown that up to 83% of babies get sunburned their first year of life. This is our fault, not theirs. Sunburns at an early age can increase the risk for melanoma skin cancer on the trunk later in life. Sun exposure is also a poor way to get vitamin D for infants because most will get far more damaging sun than they need to make vitamin D — we adults tend to over cook them.
Here are five tips to keep your baby safe this summer: Read more »

It doesn’t make sense: If sunlight causes cancer, why are human beings so drawn to it, flocking to sunny beaches for vacation time and hoping for sunshine after a rainy spell?
One answer, says David Fisher, chief of dermatology at Harvard-affiliated Massachusetts General Hospital in Boston, may be that humans are literally addicted to sunshine so our skin can make vitamin D. New evidence suggests that we get the same kick out of being in the sun that we get from any addictive substance or behavior. It stimulates the so-called “pleasure center” in the brain and releases a rush of feel-good chemicals like endorphins.
So there may be more than a desire to look good in a tan behind the urge to soak up the sun’s rays. This craving may be a survival mechanism that evolved over thousands of years because humans need vitamin D to survive. Skin makes this crucial vitamin when it is exposed to sunlight. There isn’t much vitamin D in food (except in some of today’s fortified foods) so the human brain rewards us with a rush of pleasure when we seek out the sun and get vitamin D.
Seeking sunshine can be downright dangerous. As Fisher points out, Read more »

While vacationing in Idaho and Montana last week (blissfully off the grid), I experienced something beautiful: altitude. At 6,260 feet Stanley, Idaho is a mile higher than my home in San Diego. The skies there were a brilliant blue. There was daylight well after 10PM. The mornings were a chilly 35 degrees. And I got sunburned.
How can this be? Montana is over 1,000 miles north of San Diego. Shouldn’t the sun be stronger down here? Read more »
