| bivalent gas gangrene antitoxin | Antitoxin specific for the toxins of Clostridium perfringens and C. Septicum. (05 Mar 2000) |
|---|---|
| gangrene | <pathology> Death of tissue, usually in considerable mass and generally associated with loss of vascular (nutritive) supply and followed by bacterial invasion and putrefaction. Compare: necrosis. Origin: L. Gangraena, Gr. Gangraina = an eating sore (18 Nov 1997) |
| gas gangrene | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| gas gangrene antitoxin | Antitoxin specific for the toxin of one or more species of Clostridium that cause gaseous gangrene and associated toxaemia, especially C. Perfringens C. Novyi, C. Histolyticum, and commercially available preparations are usually polyvalent, i.e., contain antitoxin for two or more species. Synonym: pentavalent gas gangrene antitoxin. (05 Mar 2000) |
| venous gangrene | Moist gangrene due to obstruction in the return circulation. Synonym: venous gangrene. (05 Mar 2000) |
| Meleney's gangrene | Undermining ulcer of the skin and subcutaneous tissues, usually following an operation, caused by a synergistic interaction between microaerophilic nonhemolytic streptococci and aerobic haemolytic staphylococci. Synonym: Meleney's gangrene, progressive bacterial synergistic gangrene. (05 Mar 2000) |
| pentavalent gas gangrene antitoxin | Antitoxin specific for the toxin of one or more species of Clostridium that cause gaseous gangrene and associated toxaemia, especially C. Perfringens C. Novyi, C. Histolyticum, and commercially available preparations are usually polyvalent, i.e., contain antitoxin for two or more species. Synonym: pentavalent gas gangrene antitoxin. (05 Mar 2000) |
| moist gangrene | Ischemic necrosis of an extremity with bacterial infection, producing cellulitis adjacent to the necrotic areas. Synonym: moist gangrene. (05 Mar 2000) |
| cold gangrene | A form of gangrene in which the involved part is dry and shriveled. Synonym: cold gangrene, mummification necrosis, mummification. (05 Mar 2000) |
| white gangrene | Death of a part accompanied by the formation of grayish white sloughs. Synonym: leukonecrosis. (05 Mar 2000) |
| haemorrhagic gangrene | Gangrene occurring rarely in advanced meningococcal septicaemia. (05 Mar 2000) |
| Pott's gangrene | Dry gangrene occurring in the aged in consequence of occlusion of an artery, particularly affecting the extremities. Synonym: Pott's gangrene. (05 Mar 2000) |
| cutaneous gangrene | Gangrene of the skin characterised by sloughing; may occur in shingles or in any acute infection that interferes with superficial circulation. (05 Mar 2000) |
| presenile spontaneous gangrene | Gangrene occurring in middle life as a result of thromboangiitis obliterans. (05 Mar 2000) |
| pressure gangrene | <dermatology> A chronic ulcer that appears in pressure areas in debilitated patients confined to bed or otherwise immobilised, due to a circulatory defect from the enhanced tissue pressure in high-contact areas, often occurring over a bony prominence (for example sacral decubitus).
