This is a biomedical research study on the determination of adrenal steroids. It has been proposed in recent years as a tool for the diagnostic orientation of an adrenal pathology. The main objective is to analyze the distribution of blood and urinary adrenal steroid values in a population of 60 controls. The secondary objective is to establish reference values for each of these parameters, if their distribution permits, and to study the possible link between the blood pressure level, the orthostatism state, the potassium level and these adrenal steroids.

The management of adrenal crisis is often problematic and the time to adequate treatment is frequently delayed.The aim of the study is to evaluate the management of adrenal emergencies req...
The purpose of this study is to determine if certain MRI sequences can accurately diagnose adrenal masses of unknown origin.
In autoimmune adrenal insufficiency, or Addison's disease (AD), the immune system attacks the adrenal cortex. As a result, the adrenal cells producing hormones such as cortisol and aldoste...
The purpose of this survey is to assess patients with chronic primary or secondary adrenal failure regarding subjective health status, incidence and causes of adrenal crisis, hormone repla...
The purpose of this study is to find out if your adrenal glands are normal or abnormal. This can be determined by whether or not your adrenal gland concentrates more of a labeled building ...
To report our management of bilateral adrenalectomy with autologous adrenal gland transplantation for persistent Cushing's disease, and to discuss the feasibility of autologous adrenal transplantatio...
Prolonged adrenal stimulation by corticotropin, as in long-standing Cushing´s disease (CD), leads to diffuse to nodular hyperplasia. Adrenal functional autonomy has been described in a subset of pati...
Castration-resistant prostate cancer (PCa) almost invariably occurs after androgen deprivation therapy (ADT) for metastatic disease and is driven in part by androgen synthesis within the tumor. 3β-hy...
We performed 18F-FDG PET/CT scan to assess the SUVmax values in the different adrenal masses including Cushing syndrome, pheochromocytoma, primary hyperaldosteronism and nonfunctional adrenal adenomas...
Adrenal crisis, the most feared complication of adrenal insufficiency, is a potentially life-threatening state of acute glucocorticoid deficiency. After successful surgery for Cushing's syndrome, many...
An adrenal disease characterized by the progressive destruction of the ADRENAL CORTEX, resulting in insufficient production of ALDOSTERONE and HYDROCORTISONE. Clinical symptoms include ANOREXIA; NAUSEA; WEIGHT LOSS; MUSCLE WEAKNESS; and HYPERPIGMENTATION of the SKIN due to increase in circulating levels of ACTH precursor hormone which stimulates MELANOCYTES.
Neoplasm derived from displaced cells (rest cells) of the primordial ADRENAL GLANDS, generally in patients with CONGENITAL ADRENAL HYPERPLASIA. Adrenal rest tumors have been identified in TESTES; LIVER; and other tissues. They are dependent on ADRENOCORTICOTROPIN for growth and adrenal steroid secretion.
Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.
The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.
A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.
