I was searching for some articles (at the site you posted Carol, Thanks) and ran across an article on Dex treatment. I think several parents who post here have children on Dex. I could only read the abstract, but the article sounded interesting. Here is the cite if anyone is interested.

Dex treatment of virilizing CAH and the ability to achieve normal growth. Pediatrics 2000 Oct, 106 (4) 767-73 Rivkes, SA and Crawford, JD
