American Academy of Dermatology Awards Dr. Woodall with Highest Honor

Congratulations to Dr. Woodall! The American Academy of Dermatology awarded our very own Dr. Woodall with the highest honor that a member can receive in the Academy's Volunteer Recognition Program. One award is given each month to an AAD member, and the winner is profiled in Dermatology World. Award-winners are chosen based on the significance of the work they have done and the extraordinary/uniqueness of the volunteer activity.  All nominees will remain on the selection list for up to three years. Please read the article featured on the Academy's website:

Raising funds for community health care can be a difficult proposition under the most forgiving of circumstances. For Rock Hill, S.C., dermatologist Timothy Woodall, MD, the challenge is to raise those funds in a poor rural community. As a member of the board of the Union County Healthcare Foundation for seven years — six of those as chairman — he has been tasked with raising funds for the hospital district, emergency services, and local nursing homes. Dr. Woodall has spent that time outperforming expectations.

“Serving others like this, it’s what my parents raised me to do.”

Union County, made up of former mill towns located in the north of the state, consistently struggles with high unemployment; the October 2011 rate reached 16.7 percent. Despite this, Dr. Woodall has managed to raise over $750,000 for county health services during his time heading the foundation’s fundraising.

“When I was asked to serve on the board, it was a no-brainer. I can raise money for a number of different causes, and it all goes into the community. It makes a lot of sense for me as a physician.”

One of Dr. Woodall’s largest projects was raising funds for the purchase of a state-of-the-art rescue vehicle, which can transmit EKG data to the local emergency room and is also able to affect a river rescue if necessary.

Apart from his work with the foundation, Dr. Woodall also undertakes fundraising and volunteerism through his local church. He put on a golf tournament to purchase a water filtration system for a Haitian village stricken with cholera.

“Every Thanksgiving, my family used to work with local churches to feed the needy. My parents were always very involved with different charity organizations. There was no epiphany, it’s just what I’ve always done, and it’s been immensely satisfying.”

2013 Skin Allergen of the Year is in Many Common Products

Since 2000, the American Contact Dermatitis Society names an “Allergen of the Year” to draw attention to chemicals often causing contact dermatitis. Contact dermatitis is an allergy that has a different mechanism than allergies like hay fever or peanut, which are often immediate in the onset of symptoms. Contact dermatitis is a delayed allergic reaction and usually arises 24-48 hours after exposure. It produces an itchy red rash that can blister, and it often takes several days to weeks for the rash to dry up and flake off.


Methylisothiazolinone (MI) was announced as the 2013 Allergen of the Year in the journal Dermatitis earlier this year. MI is a biocide often used to control mold or bacterial growth. If a cosmetic product has water in it, it has to have a preservative like MI so bacteria will not grow. MI can be found in some face creams, mascaras, shampoos, body washes and even wet wipes.


Rashes can be caused by a number of things, including chemicals like MI. If you have a persistent skin rash, be sure to call us at 803.329.6030 or book your appointment online.

The Science of Summer: What Causes Sunburns?

Summer means lots of out-of-doors time. Whether at beaches, barbeques, hanging out in the park or at the pool, most people catch more sun rays this season than other times of the year. In the process, some will get a suntan while others, unfortunately, will experience the painful redness, peeling and blistering that can occur with a bad sunburn.


So what is the skin up to when it starts soaking up sunlight and changing its hue this summer? Essentially, a suntan results from the body's natural defense mechanism kicking in against damaging ultraviolet sun rays. When the defenses are overwhelmed, a toxic reaction occurs, resulting in sunburn.

The defense mechanism is a pigment called melanin, which is produced by cells in our skin called melanocytes. Melanin absorbs ultraviolet light and dissipates it as heat.


"Melanin is a natural sunscreen," said Gary Chuang, an assistant professor of dermatology at Tufts University School of Medicine. "When your body senses sun damage, what it does is it starts sending out melanin into surrounding cells and tries to protect them and shield them from getting more damage."


Everyone has about the same number of melanocytes, Chuang said, but people vary in how much and what colors of melanin they produce. Darker skinned people have more natural sunscreen at their disposal. Even when getting a boost from artificial sunblock creams and the like, though, people are all ultimately vulnerable to the sun's ultraviolet wrath.


"It doesn't matter how much sunscreen you have on — if you are lying there forever and ever, some of the radiation will definitely penetrate through," said Chuang. "Even if you have a tan you can get a sunburn, and people with dark skin types can get a sunburn if out long enough."


DNA buster

Invisible ultraviolet light carries more energy than the light visible to humans, and this energy packs a tiny punch.

When a UV photon strikes the skin, it can damage the DNA in the body's cells. It does this by breaking the orderly bonds between the four nucleotides, adenosine, thymine and guanine. So-called thymine dimers form, when two thymine nucleotides bind together, throwing the whole shape of the DNA molecule out of whack.

The cell with the messed-up DNA usually then commits suicide, a process called apoptosis. "The cells receive so much radiation that they undergo apoptosis," said Chuang.


Crimson carnage

The body senses this destruction and over the course of several hours starts flooding the area with blood to help with the healing process. Painful inflammation occurs as well. Usually within half a day of overindulging in the sun, the characteristic steamed-lobster look of a sunburn begins to make itself known, and felt.


With very bad sunburns, thermal damage in the manner of second-degree burns not unlike that caused from being too close to a fire can set in. The skin blisters as a result, with liquid-filled, protective bubbles forming over areas of tissue damage.


Several days after the initial sun-wrought carnage, dead skin cells in the blasted region will start to peel off. "The cell signals the body that it has received enough radiation and has a chance of becoming mutated, so [the cell says] 'Now you need to die off before it becomes problematic,' and you get that sloughing of the skin," said Chuang.


Sometimes the cells with sun-caused mutated DNA do turn into problem cells, however, that do not call it quits and keep proliferating as cancers. "The UV light causes random damages in the DNA and DNA repair process such that cells acquire the ability to avoid dying," said Chuang.

Skin cancer is the most common form of cancer in the United States. People who allow themselves to get sunburnt repeatedly are at much higher risk. The risk for the deadliest form of skin cancer, called melanoma, doubles for someone who has received five or more sunburns, according to the Skin Cancer Foundation.


Beating back the sun

To avoid skin cancer, as well as the painful nuisance of a sunburn, Chuang advises people to cover up and apply sunscreen liberally.


"The sunscreens I like are physical blockers," Chuang said. In sunblock formulas, look for the ingredients of titanium dioxide or zinc oxide, because they "reflect off UV radiation," he said. Chuang is also is a big fan of hats. "Wear hats," he said. "People think hats are going out of fashion, but they are a very basic physical blocker of the sun."

Dr. Richard White Lectures at the American Academy of Dermatology International Annual Convention


We welcome Dr. White back from the American Academy of Dermatology Annual meeting in San Diego, California, where he lectured other dermatologists from around the world how to identify patients and families at risk for cancers which can be inherited. Dr. White's wife, Brook White, a Cancer Genetic Counselor, also lectured with him on the importance of the genetic counseling for the patient and family.
