My nephew is 7 months old and lives in Mongolia. Recently, he was taken to the hospital for "turning blue" and "shaking". The doctors say he has an enlarged thymus and the hospital does not provide service for this condition. What can we do? What treatments are available? What are the possible outcomes? How immediate is this emergency? (please note the doctors say his chest x-rays are normal. I don't know how the doctors arrived at this conclusion, and translating from English to Mongolian is less than perfect, but my Mongolian wife and I (American husband) are very concerned.)
