| pituitary myxoedema | Myxoedema resulting from inadequate secretion of the thyrotropic hormone; commonly occurs in association with inadequate secretion of other anterior pituitary hormones. (05 Mar 2000) |
|---|---|
| pituitary stalk section | Transection of the neurovascular connection between the hypothalamus and the pituitary gland. (05 Mar 2000) |
| posterior pituitary | The cleaned, dried, and powdered posterior lobe obtained from the pituitary body of domestic animals used for food by humans; an oxytocic, vasoconstrictor, antidiuretic, and a stimulant of intestinal motility. Synonym: desiccated pituitary, hypophysis sicca. (05 Mar 2000) |
| postpartum pituitary necrosis syndrome | <syndrome> Hypopituitarism arising from a severe circulatory collapse postpartum, with resultant pituitary necrosis. Synonym: postpartum pituitary necrosis syndrome, thyrohypophysial syndrome. (05 Mar 2000) |
| Cushing's pituitary basophilism | <disease> An increased concentration of glucocorticoid hormone in the bloodstream (produced by the adrenal gland) secondary to a pituitary tumour that is secreting the hormone adrenocorticotropic hormone (ACTH). ACTH serves to stimulate the adrenal gland to produce excess glucocorticoids. (27 Sep 1997) |
| hyaline bodies of pituitary | Accumulations of a gelatinous neurosecretory substance in the axons of the hypothalamohypophyseal tract in the posterior lobe of the hypophysis. (05 Mar 2000) |
| desiccated pituitary | The cleaned, dried, and powdered posterior lobe obtained from the pituitary body of domestic animals used for food by humans; an oxytocic, vasoconstrictor, antidiuretic, and a stimulant of intestinal motility. Synonym: desiccated pituitary, hypophysis sicca. (05 Mar 2000) |
| dwarfism, pituitary | A form of dwarfism due to absence or hypofunction of the anterior pituitary gland. (12 Dec 1998) |
| enlarged pituitary infundibulum | <radiology> Histiocytosis X, eosinophilic granuloma, Hand-Schuller-Christian disease, Letterer-Siwe disease, sarcoidosis (12 Dec 1998) |
| accessory adrenal | An island of cortical tissue separate from the adrenal gland, usually found in the retroperitoneal tissues, kidney, or genital organs. Synonym: adrenal rest. (05 Mar 2000) |
| acute 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) |
| adenoma, adrenal cortical | A benign neoplasm of adrenal cortical cells resembling normal adrenal cells histologically but possessing functional autonomy. In general it does not exceed 5 cm in its largest dimension, although benign tumours exceeding 20 cm have been reported. Adrenal cortical adenomas produce hypercortisolism and hyperaldosteronism, but seldom produce adrenogenital syndromes. For the most part the prognosis after surgery is reasonably favourable. (12 Dec 1998) |
| adrenal | <anatomy> Suprarenal. Origin: Pref. Ad- + renal. Source: Websters Dictionary (01 Mar 1998) |
| adrenal adenoma | <radiology> Benign adrenal tumour, hyperfunctioning adenoma can cause, primary hyperaldosteronism, Cushing syndrome, nonfunctional adenoma seen in 2-8% of population, differentiate from metastasis, MRI: metastasis bright on T2, biopsy, follow see: adrenal mass (12 Dec 1998) |
| adrenal androgen | Any androgenic hormone of adrenocortical origin; e.g., dehydroepiandrosterone (and its sulfate), androstenedione, 11b-hydroxyandrostenedione. (05 Mar 2000) |
