Deb --
Try getting in touch with Jackie, Tanimara
http://dmoz.org/cgi-bin/send.cgi?toeditor=tanimara
That is a form to contact her. She has been looking into thyroid problems in pyrs.
Also Barb has posted a place to have the complete screen sent for evaluation -- sorry I can't remember it , but maybe someone will have it. You really need to get the whole screen done.
Good Luck
