John, I have been doing medical research for a friend whose 2 (grown) daughters were possibly exposed to toxic gas leaks from a titan missile silo accident almost 20 years ago. Both developed serious disorders about 5 years ago--in their early 20's. One has a pituitary tumor (brain), and the other has Lupus; no family history of either problem. I have a ton of articles, data, and many web sites that may help you. There is a lot, so I will email you privately later today. Rosemary Russell (49, 2 1/2 yrs.)
