While I personally think that the endocrinology community have many positions not supported by science (e.g. double-blind controlled studies) and am dismayed at the harm inflicted on patients, should Wikipedia be the venue for pushing those beliefs onto others?  I think that the article should fairly reflect both sides of the controversy. 
 :Secondly, most of the treatment issues probably do not belong here.  This should simply be an article about desiccated thyroid.  It makes more sense to put controversies over diagnosis and treatment on the pages where that belongs, e.g. on the page on hypothyroidism.
