FDA clears laser therapy for vitiligo:

The US FDA has cleared for sale what it claimed is the first excimer laser system for treating vitiligo, a skin disease that causes a loss of pigmentation. The XTRAC laser device, made by Photomedex of Radnor, Pennsylvania, eradicates the white spots caused by vitiligo, restoring the skin to the same condition as before the onset of the disease. The company says that until now, there has been no known cure or effective treatment for the disease, which is known to affect around two to four million people in the US.
