| 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) |

Can occur as result of Addison's disease or Addisonian crisis; characterised by hypovolaemia, hypotension. (05 Mar 2000) |
| sickle cell crisis | <haematology> Disease common in races of people from areas in which malaria is endemic. The cause is a point mutation in the allele that codes for the beta chain of haemoglobin with a substitution of (valine for glutamic acid at position 6. The defective haemoglobin (HbS) crystallizes readily at low oxygen tension. In consequence, erythrocytes from homozygotes change from the normal discoid shape to a sickled shape when the oxygen tension is low and these sickled cells become trapped in capillaries or damaged in transit, leading to severe anaemia. In heterozygotes, the disadvantages of the abnormal haemoglobin are apparently outweighed by increased resistance to Plasmodium falciparum malaria, probably because parasitised cells tend to sickle and are then removed from circulation. Symptoms include joint pain, acute abdominal pain, and ulcerations of the lower extremities. Origin: Gr. Haima = blood (18 Nov 1997) |
