| symptomatic porphyria | A form of hepatic porphyria (porphyria, hepatic) characterised by photosensitivity resulting in bullae that rupture easily to form shallow ulcers. This condition occurs in two forms: a sporadic, nonfamilial form that begins in middle age and has normal amounts of uroporphyrinogen decarboxylase with diminished activity in the liver; and a familial form in which there is an autosomal dominant inherited deficiency of uroporphyrinogen decarboxylase in the liver and red blood cells.

| symptomatic pruritus | Itching occurring as a symptom of some systemic disease. (05 Mar 2000) |
| symptomatic reaction | An allergic response similar to the original one, but occurring after the use of a test or therapeutic dose of an allergen or atopen. (05 Mar 2000) |
| symptomatic tetany | Tetany from any cause in which neuromuscular hyperexcitability are clearly evident, as opposed to latent tetany. Synonym: symptomatic tetany. (05 Mar 2000) |
| symptomatic torticollis | Stiff neck due to cervical or neck myositis, chiefly of the sternocleidomastoid, occurring especially in children. Synonym: rheumatic torticollis. (05 Mar 2000) |

| paroxysmal cold haemoglobinuria | <haematology> A rare blood disorder caused by antibodies which destroy red blood cells upon exposure to the cold. The antibodies are formed against a specific blood group and are triggered by the cold. The cause is unknown but the disease has been associated with syphilis and some viral infections. Serum haemoglobin and urine haemoglobin are increased during the attacks. The disease is chronic and treatment is difficult. Some cases resolve spontaneously without treatment. Origin: Gr. Ouron = urine (27 Sep 1997) |

| warm-cold haemolysin | Haemolysin which combines with red blood cells at temperatures below 20캜 and are eluted at warmer temperatures, e.g., 30 to 37캜. See: Donath-Landsteiner cold autoantibody, haemagglutinating cold autoantibody. (05 Mar 2000) |

| cold agglutination | The agglutination of red blood cells by their own serum (see autoagglutination), or by any other serum when the blood is cooled below body temperature, but most pronounced below 25캜; the phenomenon results from cold agglutinins; may be seen occasionally in the blood of apparently normal persons or as a pathologic finding in patients with primary atypical pneumonia, infectious mononucleosis, and other viral diseases, certain protozoan infections, or lymphoproliferative neoplasms. See: autoagglutination. (05 Mar 2000) |
