Control of prolactin secretion by the hypothalamic catecholamines.

The neuroendocrine control of prolactin secretion is very complex. Even though the hypothalamus exerts a profound inhibitory influence upon the secretion of this hormone, the mechanism(s) involved is poorly understood. The cerebrospinal fluid seems to be becoming increasingly important as regards neuroendocrine regulatory mechanisms involving prolactin. Pharmacological agents such as apomorphine and many of the ergot alkaloids are very effective inhibitors of the secretion of prolactin. Still other pharmacological agents such as DMPEA, alpha-methyldopa, reserpine, and certain of the phenothiazines are very effective in causing a stimulation of prolactin secretion.

Empty sella syndrome. Sequela of the spontaneous remission of acromegaly.

Untreated acromegaly is usually a progressive disorder resulting in early death from cardiovascular or pulmonary complications. Although spontaneous remission of the metabolic features of acromegaly is not uncommon, its correlation with return to truly normal serum growth hormone concentrations is not routinely documented. This study reports a patient with the empty sella syndrome occurring as a sequel to the spontaneous remission of acromegaly. This association, as well as the preservation of normal anterior-pituitary function, suggests that selective tumor infarction resulted in the "empty sella" and cessation of active acromegaly.
