Adrenal disease can refer to changes to the adrenal cortex and/or to the adrenal medulla. The most common form of adrenal medulla pathology is a pheochromocytoma. These rare tumors are usually much larger than tumors of the adrenal cortex and can remain unnoticed for a long time. Although cases have been reported where pheochromocytomas have been diagnosed based on histologic characteristics of...

BACKGROUND AND PURPOSE Cushing syndrome appears after chronic exposure to elevated glucocorticoid levels. Cortisol excess may alter white matter microstructure. Our purpose was to study WM changes in patients with Cushing syndrome compared with controls by using DTI and the influence of hypercortisolism. MATERIALS AND METHODS Thirty-five patients with Cushing syndrome and 35 healthy controls,...

OBJECTIVES In about 15-20% of patients with ACTH-dependent Cushing's syndrome the source of ACTH is outside the pituitary gland. Pulmonary tumours are the most frequent, yet not unique, source of ectopic ACTH. In some instances the localisation of an ACTH-secreting tumour may be problematic. Occult ectopic ACTH secretion indicates the occurrence of ACTH-dependent hypercortisolism with an unknow...

OBJECTIVE The purpose of this study was to evaluate the direct action of desmopressin (agonist of vasopressin) on the hypophysis and the three zones of the adrenal cortex in patients with different forms of hypercortisolism. DESIGN Forty-three patients with hypercortisolism-21 with Cushing's disease (14 females, 7 males), 11 with extrapituitary, ectopic tumours (5 females, 6 males), and 11 wi...

Endogenous Cushing's syndrome is a grave disease that requires a multidisciplinary and individualized treatment approach for each patient. Approximately 80% of all patients harbour a corticotroph pituitary adenoma (Cushing's disease) with excessive secretion of adrenocorticotropin-hormone (ACTH) and, consecutively, cortisol. The goals of treatment include normalization of hormone excess, long-t...

Mifepristone is the first and only available glucocorticoid receptor antagonist. It was initially mainly considered as a so-called 'contragestive' pill due to its antiprogestin activity. In this review, we summarize the results of mifepristone reported in the literature as a treatment of Cushing's syndrome. Most of the patients were treated due to unsuccessful surgery and/or partially effective...

While many features of the adrenocortical axis are unchanged with age in humans, there is a pattern of senescent hypercortisolism. This occurs basally, following threshold doses of dexamethasone, and in synergy with depression or Alzheimer's disease. An understanding of neuroendocrine aging is important, for both its gerontological implications, and determination of normative values for compari...
