| crisis | A sudden paroxysmal intensification of symptoms in the course of a disease. Origin: L., Gr. Krisis (18 Nov 1997) |
| crisis intervention | Brief therapeutic approach which is ameliorative rather than curative of acute psychiatric emergencies. Used in contexts such as emergency rooms of psychiatric or general hospitals, or in the home or place of crisis occurence, this treatment approach focuses on interpersonal and intrapsychic factors and environmental modification.

| salt-depletion crisis | Severe illness resulting from loss of sodium chloride, usually in urine (i.e., salt-losing nephritis), in sweat following severe exercise in hot weather, or in intestinal secretions, as in cholera. Can occur as result of Addison's disease or Addisonian crisis; characterised by hypovolaemia, hypotension. (05 Mar 2000) |
| pseuodoparalysis, spastic | Better known as creutzfeldt-jakob disease. A dementing disease of the brain. It is believed due to an unconventional (not a bacteria or virus), transmissible agent called a prion. Symptoms of cjd include forgetfulness, nervousness, jerky trembling hand movements, unsteady gait, muscle spasms, chronic dementia, balance disorder, and loss of facial expression. Cjd is classified as a spongiform encephalopathy. most cases occur randomly (sporadically), but inherited forms exist. There is neither treatment nor cure for cjd. Other names for cjd include creutzfeldt-jakob syndrome and jakob-creutzfeldt disease. (12 Dec 1998) |
| 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) |
| spastic | 1. Of the nature of or characterised by spasms. 2. Hypertonic, so that the muscles are stiff and the movements awkward. 3. A person exhibiting spasticity, such as occurs in spastic paralysis or in cerebral palsy. Origin: Gr. Spastikos (13 Nov 1997) |
| spastic abasia | Abasia due to a spastic contraction of the muscles when an attempt is made to walk. (05 Mar 2000) |
| spastic anaemia | Local anaemia resulting from nontransitory contraction of the arterial vessels in the affected region. (05 Mar 2000) |
| spastic colitis | See Syndrome, irritable bowel. (12 Dec 1998) |
| spastic colon | A bowel disorder with no demonstrable organic abnormality. Often referred to as a functional bowel disorder or spastic colon. Symptoms include episodic, crampy abdominal pains often related to anxiety. (27 Sep 1997) |
| spastic diplegia | A type of cerebral palsy in which there is bilateral spasticity, with the lower extremities more severely affected. Compare: flaccid paralysis. Synonym: Erb-Charcot disease, infantile diplegia, Little's disease, spastic spinal paralysis, tabes spasmodica. (05 Mar 2000) |
| spastic dysarthria | Dysarthria caused by lesions along the corticobulbar tracts. Synonym: rigid dysarthria. (05 Mar 2000) |
| spastic dysphonia | A spasmodic contraction of the intrinsic muscles of the larynx excited by attempted phonation, producing either adductor or abductor subtypes caused by central nervous system disease. A localised form of movement disorder. Synonym: phonic spasm, spastic dysphonia. (05 Mar 2000) |
