TURLOCK, Calif. — For much of his young life, Jorge Sanchez regularly gasped for air, at times coughing so violently that he'd almost throw up. His mother whisked him to the emergency room late at night and slept with him to make sure he didn't stop breathing.

"He's had these problems since he was born, and I couldn't figure out what was triggering his asthma," Fabiola Sandoval said of her son, Jorge, now 4. "It's so hard when your child is hurting. I was willing to try anything."
