The ACTH test has been used to confirm the diagnosis of adrenal insufficiency and the classic and the non-classic adrenal hyperplasia due to the 3-HSD, 21 OH e 110H deficiencies. This article reviews the historical aspects of the use of ACTH in the diagnosis of hirsutism and points out its mains indications. In spite of new biological molecular advances in the diagnosis of adrenal enzymatic def...

Objective: Bi lateral adrenalectomy or unilateral adrenalectomy and contralateral partial adrenalectomy are indicated for the treatment of ACTH-independent macronodular adrenal hyperplasia. Independent of the surgical procedure, the prognosis is poor. This paper discusses a new treatment method and its efficacy for treating nodular adrenal hyperplasia. Methods: We performed a retrospective revi...

BACKGROUND AND PURPOSE Bilateral adrenalectomy or unilateral adrenalectomy and contralateral partial adrenalectomy are indicated for the treatment of ACTH-independent macronodular adrenal hyperplasia. Independent of the surgical procedure, the prognosis is poor. This article discusses a new treatment method and its efficacy for treating nodular adrenal hyperplasia. METHODS We performed a retr...

The adrenal gland is an essential stress-responsive organ that is part of both the hypothalamic-pituitary-adrenal axis and the sympatho-adrenomedullary system. Chronic stress exposure commonly increases adrenal weight, but it is not known to what extent this growth is due to cellular hyperplasia or hypertrophy and whether it is subregion specific. Moreover, it is not clear whether increased pro...

Compensatory adrenal growth after unilateral adrenalectomy (ULA) leads to adrenocortical hyperplasia. Because zonal growth contributions are not clear, we characterized the phenotype of cortical cells that proliferate using immunofluorescence histochemistry and zone-specific cell counting. Rats underwent ULA, sham adrenalectomy (sham), or no surgery and were killed at 2 or 5 days. Adrenals were...
