title: [Endocrinology of the chiasma syndromes (author's transl)].
abstract: A wealth of new knowledge about the function of the hypothalamo-hypophyseal system has been accumulated over the past ten years and progress keeps going at a fast pace. Several factors have contributed to this explosive growth: Pituitary hormones can now be measured by radio-immunoassay in body fluids, hypothalamic stimulating and inhibiting factors have been identified and are available for clinical studies and dynamic tests have been developed for detailed investigations of minor disturbances in the pituitary control system. A tremendous gain in accuracy of clinical diagnosis and endocrine follow-up is one of the consequences. Furthermore, new clinical pictures have emerged such as several variants of the hyperprolactinemia-hypogonadism syndrome or the concept of pituitary microadenoma. At the same time, neuropharmacology is also developing at a tremendous pace and exceedingly interesting perspectives linking neurotransmission with endocrinology and with various diseases of the brain are emerging. One highlight is the discovery of bromoergocryptine as a dopaminergic agonist, active in suppressing prolactin secretion as well as in treating Parkinsonism. In a second part of this presentation 5 cases with pituitary disease are presented. They were selected to cover part of the wide range of clinical signs and symptoms produced by tumours of the pituitary region. There is indeed no good relationship between ophthalmo-neurologic symptoms, destruction of the bony sella and endocrine disturbances.
