SALT LAKE CITY -- A team of medical volunteers, mostly from Utah, is preparing for a trek to one of the most remote countries in the world. It's an annual effort doing what many experts thought was a bad idea: teaching an advanced form of high-tech surgery in a primitive economy.

It's so off-the-beaten-track, a lot of people probably couldn't find Mongolia on a map. By some accounts, the Asian country's economy is like the United States in the 1880s, and the people there are troubled by a very unusual medical problem.
