After suffering with skin problems most of her young life, Jewel Harmon saw a pediatric dermatology expert from Louisville Wednesday — without ever leaving her hometown of Morehead, Ky., 150 miles away. The 5-year-old visited the doctor through "telemedicine," using videoconferencing to link patients and physicians from distant locations. "It is wonderful," said her mother, Jessica Noble, 29. "It's hard for me to get around. And I can't drive all the way to Louisville; I don't have reliable transportation to drive that far."
