| 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) |
| acute adrenocortical insufficiency | Severe adrenocortical insufficiency when an intercurrent illness or trauma causes an increased demand for adrenocortical hormones in a patient with adrenal insufficiency due to disease or use of relatively large amounts of similar hormones as therapy; characterised by nausea, vomiting, hypotension, and frequently hyperthemia, hyponatraemia, hyperkalaemia, and hypoglycaemia; can be fatal if untreated. Synonym: addisonian crisis, adrenal crisis, Bernard-Sergent syndrome. (05 Mar 2000) |
| adrenal gland insufficiency | <endocrinology> A condition that results from the inadequate production of adrenal hormones (see Addison's disease). (27 Sep 1997) |
| adrenal insufficiency | <endocrinology> A condition that results from the inadequate production of adrenal hormones (see Addison's disease). (27 Sep 1997) |
| adrenocortical insufficiency | Loss, to varying degrees, of adrenocortical function. Synonym: hypocorticoidism. (05 Mar 2000) |
| aortic insufficiency | A congenital or acquired heart valve abnormality that results in the abnormal back flow of blood in the aorta, through an incompetent aortic valve and into the left ventricle. Chronic aortic insufficiency leads to enlargement of the left ventricle and pulmonary congestion. If left uncorrected, congestive heart failure will result. Aortic valve replacement is eventually necessary in most cases of significant valvular incompetence. (27 Sep 1997) |
| aortic valve insufficiency | Backflow of blood from the aorta into the left ventricle, owing to imperfect functioning of the aortic semilunar valve. (12 Dec 1998) |
