[T.R.H. test in 93 cases of thyroid disease].

The authors used the stimulation of TSH test by intravenous injection of TRH in 93 patients. They obtained a negative or weak response in thyrotoxicosis, toxic adenomas, and Means syndrome, and a normal response with non-extinctive hot nodules. The response was positive and high in primary hypothyroidism. The results are sometimes paradoxal in hypothalamo-pituitary pathology even after hypophysectomy: a delayed and elevated response is in favour of a pituitary reserve of non-utilised TSH. In non-functional goitres and thyroiditis, the sometimes positive responses obtained are an indication for substitutive and depressive therapy.
