When Anne Soloviev went to Braun Dermatology and Skin Cancer Center in Washington, D.C., for her semiannual dermatology checkup in early January, the physician assistant diagnosed fungus in two of her toenails.

Soloviev hadn't complained about her toenails or even noticed a problem.

But the physician assistant offered a solution anyway. She called in a prescription for an antifungal medicine to a specialty pharmacy with mail-order services that would send it to Soloviev's Capitol Hill home.
