[Diagnosis of hyperprolactinaemias: respective value of response to THR and to bromocriptine (author's transl)].

Seventy tests of stimulation with hypothalamic thyreotrophic hormone liberation factor, and 35 bromocriptine inhibition tests were carried out on a routine basis in patients with latent or frank hyperprolactinaemia. Pathological hyperprolactinaemia does not have a single clinical pattern: frank, it takes the form either of an exteriorised pituitary adenoma (14 cases), or of an amenorrhoea-galactorrhoea syndrome with or without micro-adenoma (12 cases); latent, it takes the form either of isolated amenorrhoea (17 cases) or of dysovulatory sterility (16 cases). Amongst the dynamic tests available, it is worthwhile to make a choice, and in the case of frank hyperprolactinaemia, the authors propose use of the bromocriptine inhibition test in the first instance. The TRH test is reserved for verification of the results of neurosurgery. As far as latent hyperprolactinaemia is concerned, it may be identify only by the TRH test, with the resultant possibility of specific treatment.

[Changes in plasma level of corticotropin after intravenous injection of metyrapone. Value of this test in pituitary pathology].

The Metyrapone was given, the morning, in perfusion intravenous of saline serum over 2 hours. A.C.T.H. levels were determined before and at 2, 4, 8 and 24 hours. Sixteen normal subjects adults served on controls with 1 g of Metyrapone. Sixteen other normal subjects with 2 g of Metyrapone are best responses. With this maximum dose 2 g were studied nine hypophysal adenomas with three low responses, three normal and three high responses; thirteen hypophysectomised subjects with very low peak value at 4 hours, and only two responses higher than the controls, five Cushing's syndromes with variable responses. The I.V. Metyrapone test seems to offer several advantages: it eliminates the questions about gastro-intestinal absorption of Metyrapone (oral) and the difficulties of urine collection. With the A.C.T.H. dosage on 4 hours, this is a rapid test able to put in combination other hypophysal tests.

[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.
