| adrenal apoplexy | Haemorrhage into the adrenal glands or thrombosis of the adrenal veins, followed by acute adrenal insufficiency, occurring in the Waterhouse-Friderichsen syndrome. (05 Mar 2000) |
|---|---|
| adrenal body | See adrenal gland. (12 Dec 1998) |
| adrenal calcification | <radiology> Haemorrhage, cyst, Addison's disease (e.g., TB, histo), neoplasm, pheochromocytoma, adrenal cortical adenoma/carcinoma, adrenal choristoma (myelolipoma), metastatic melanoma, Wolman disease (12 Dec 1998) |
| adrenal capsule | See adrenal gland. (12 Dec 1998) |
| adrenal cortex | <anatomy, endocrinology> This is the outer portion of the fattyacids and inhibit inflammation in allergic responses. Mineralocortoids regulate the levels of minerals such as sodium and potassium in the blood. (06 May 1997) |
| adrenal cortex injection | An obsolete treatment involving the parenteral administration of extract of the adrenal cortex; formerly used in treatment of Addison's disease. (05 Mar 2000) |
| adrenal cortical carcinomas | Large invasive and metastasizing tumours which may cause virilism or Cushing's syndrome. (05 Mar 2000) |
| adrenal cortical syndrome | <syndrome> An inexact (and obsolete) term that has been applied to Cushing's syndrome, Addison's disease, or the adrenogenital syndrome. (05 Mar 2000) |
| adrenal crisis | <endocrinology> An abrupt life-threatening state which is caused by insufficient production of cortisol by the adrenal gland. A typical finding in Addison's disease. Individuals who have been taking corticosteroids (glucocorticoids) for a prolonged period of time (weeks to months) are at risk for acute adrenal crisis if the medication is stopped abruptly. For this reason, corticosteroid medication are withdrawn slowly on a diminishing dosing schedule. Symptoms include low blood pressure (shock), weakness, headache, vomiting, fever chills, tachycardia and sweating. Treatment includes blood pressure support and intravenous hydrocortisone. (27 Sep 1997) |
| adrenal cyst | <radiology> Same characteristics as renal cysts, but less common, thick wall, septations, calcifications suggests pseudocyst (12 Dec 1998) |
| adrenal gland | <anatomy, endocrinology> This gland is found above each kidney and it made up of an outer wall (cortex) that secretes important steroid hormones and an inner portion (medulla) that produces adrenaline (adrenaline) and noradrenaline (noradrenaline). The hormones help control heart rate, blood pressure, the way the body uses food, and other vital functions. (25 Jun 1999) |
| adrenal gland hypofunction | Adrenocortical hypofunction includes all conditions in which adrenal steroid hormone secretion falls below the requirements of the body. Adrenal insufficiency may be divided into two general categories: (1) those associated with primary inability of the adrenal to elaborate sufficient quantities of hormone and (2) those associated with a secondary failure due to a primary failure in the elaboration of adrenocorticotropin. (12 Dec 1998) |
| adrenal gland insufficiency | <endocrinology> A condition that results from the inadequate production of adrenal hormones (see Addison's disease). (27 Sep 1997) |
| adrenal gland tumour | <oncology> A benign tumour or adenoma, that usually results in the excess production of adrenal gland hormones. (27 Sep 1997) |
| adrenal haemorrhage | <radiology> Neonate, right more common, 10% bilateral, birth trauma, hypoxia, septicaemia, congenital syphilis, haemorrhagic disorders (haemophilia, etc.) adult, septicaemia (Waterhouse-Friderichsen syndrome), tumour, trauma Notes: usually resolves in 4-6 weeks, adrenal insufficiency rare, even if bilateral, may calcify (12 Dec 1998) |
