Pre- and postoperative visual and endocrine functions were examined in 54 patients with so-called chromophobe pituitary adenomas operated on by the transnasal approach. The preoperative examination showed visual disturbances in 41 of 48 patients. A loss of gonadal function was present in 93% of the women and 69% of the men. Impairment of adrenal function was found in 37% and of thyroid function in 18% of patients. Hyperprolactinemia was present in 16 of 29 patients examined. The visual findings remained unchanged, normal or improved in 75% of patients. Impairment occurred in 3%. Eight patients experienced improvement of gonadal function and 3 of adrenal function, whereas no postoperative improvement of the thyroid function was observed. Deterioration of gonadal function occurred in 4, of adrenal function in 7, and of thyroid function in 9 patients. Hyperprolactinemia was reduced in all cases.
Mice treated with cortexolone during a period of chronic ethanol feeding displayed significantly less tolerance to a challenge dose of ethanol than mice fed ethanol but not given cortexolone. This glucocorticoid receptor blocker did not alter the hypnotic effects of ethanol in animals not previously given ethanol and no differences were found in ethanol consumption or blood ethanol levels between ethanol-fed mice receiving daily injections of cortexolone and the vehicle-injected controls. It was concluded that cortexolone interferes with the development of tolerance to ethanol.
