| chronic hypertensive disease | The chronic accumulative effects of long-standing high blood pressure on such vital organs as the heart, kidney, and brain. (05 Mar 2000) |
|---|---|
| hypertensive | 1. Marked by an increased blood pressure. 2. Denoting a person suffering from high blood pressure. (05 Mar 2000) |
| hypertensive angiopathy | A condition of turkeys of unknown aetiology, associated with sudden death in rapidly growing male birds. (05 Mar 2000) |
| hypertensive arteriopathy | Arterial degeneration resulting from hypertension. (05 Mar 2000) |
| hypertensive arteriosclerosis | Progressive increase in muscle and elastic tissue of arterial walls, resulting from hypertension; in longstanding hypertension, elastic tissue forms numerous concentric layers in the intima and there is replacement of muscle by collagen fibres and hyaline thickening of the intima of arterioles; such changes can develop with increasing age in the absence of hypertension and may then be referred to as senile arteriosclerosis. (05 Mar 2000) |
| hypertensive encephalopathy | A metabolic encephalopathy caused by diffuse cerebral oedema; follows an abrupt elevation of blood pressure in a long-term hypertensive patient. (05 Mar 2000) |
| hypertensive retinopathy | A retinal condition occurring in accelerated vascular hypertension, marked by arteriolar constriction, flame-shaped haemorrhages, cotton-wool patches, star-figure oedema at the macula, and papilledema. (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 For this reason, corticosteroid medication are withdrawn slowly on a diminishing dosing schedule.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) |
| addisonian 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. See: addison's disease (15 Jan 1998) |
| adolescent crisis | The emotional turmoil often accompanying adolescence. (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.

| anaphylactoid crisis | A reaction that is similar to anaphylactic shock, but which does not require the incubation period characteristic of induced sensitivity (anaphylaxis); it is unrelated to antigen-antibody reactions. Synonym: anaphylactoid crisis, pseudoanaphylactic shock. (05 Mar 2000) |
| blast crisis | <haematology> In patients with chronic myelogenous leukaemia, the progression of the diseases to an acute advanced phase, evidenced by an increased number of immature white blood cells in the circulating blood. Sometimes loosely used to describe a rapid increase in the white blood cell count of any leukaemic patient. (17 Mar 1998) |
| blood crisis | The appearance of a large number of nucleated red blood cells in the peripheral blood, accompanied by reticulocytosis and occurring in "exhausted" bone marrow in pernicious anaemia and in haemolytic icterus, a suddenly appearing leukocytosis, indicating a change for the better in the course of a grave blood disease. (05 Mar 2000) |
| gastric crisis | An attack, usually lasting several days, with severe pain in the abdomen or around the waist, accompanied by nausea and vomiting and occasionally diarrhoea; occurs in tabetic neurosyphilis. (05 Mar 2000) |
