Could be all of you have already found this site, but if not, here is the address:
http://www.healthgate.com/HealthGate/MEDLINE/search.shtml. My brother-in-law, a physician uses MEDLINE in his research. The search revealed 378 medical journal articles for the general search of “Graves’ disease” in the past two years. Some of the questions I’ve read posted to the BB were addressed. This is a good resource if you’re serious about the GD data you collect.
