| subacute necrotizing encephalomyelopathy | A rare fatal disorder, primarily of children, being both acute and chronic in onset, manifested primarily as brainstem dysfunction, with ataxia, cranial nerve palsies, pseudobulbar palsy, hemi-or quadriplegia, mental deterioration, and involuntary movements; deficiencies of pyruvate dehydrogenase or cytochrome C oxydase have been found in some patients; pathologically, there is widespread symmetric necrosis involving much of the brainstem; these changes are similar to those seen with Wernicke encephalopathy.

| subacute necrotizing myelitis | A disorder of the lower spinal cord in adult males resulting in progressive paraplegia. Synonym: angiodysgenetic myelomalacia, Foix-Alajouanine myelitis. (05 Mar 2000) |
| disseminated necrotizing leukoencephalopathy | <radiology> DNL: demyelination due to radiation and chemotherapy, decreased density in deep white matter, with or without peripheral, patchy enhancement, calcification: basal ganglia, grey/white junction (12 Dec 1998) |
| fasciitis, necrotizing | A fulminating group a streptococcal infection beginning with severe or extensive cellulitis that spreads to involve the superficial and deep fascia, producing thrombosis of the subcutaneous vessels and gangrene of the underlying tissues. A cutaneous lesion usually serves as a portal of entry for the infection, but sometimes no such lesion is found. (12 Dec 1998) |
| rheumatoid arthritis, systemic-onset juvenile | Also known as systemic-onset juvenile chronic arthritis. Still's disease presents with systemic (bodywide) illness including high intermittent fever, a salmon-coloured skin rash, swollen lymph glands, enlargement of the liver and spleen, and inflammation of the lungs (pleuritis) and around the heart (pericarditis). The arthritis may not be immediately apparent but it does appear and may persist after the systemic symptoms are gone. (12 Dec 1998) |
| portal-systemic anastomoses | Naturally-occurring venous communications between tributaries of the portal venous system and tributaries of the systemic venous system. The major portal-systemic anastomoses include: 1) oesophageal branches of left gastric vein with oesophageal veins, 2) superior rectal vein with middle and inferior rectal veins, 3) paraumbilical veins with subcutaneous veins of anterior abdominal wall, 4) retroperitoneal veins with venous branches of veins of the colon and bare area of the liver, and 5) a patent ductus venosus connecting left branch of portal vein to inferior vena cava (rare). These anastomoses are important clinically, providing collateral circulation during portal obstruction or hypertension, at which time they may become varicose. See: caput medusae, oesophageal varices, haemorrhoids. Surgically-created communications between the portal vein and the inferior vena cava or their tributaries, to relieve portal hypertension. Synonym: portacaval anastomoses. (05 Mar 2000) |
| portal-systemic encephalopathy | An encephalopathy associated with cirrhosis of the liver, attributed to the passage of toxic nitrogenous substances from the portal to the systemic circulation; cerebral manifestations may include coma. Synonym: hepatic encephalopathy. (05 Mar 2000) |
| scleroderma, systemic | A chronic, progressive dermatosis characterised by boardlike hardening and immobility of the affected skin, with visceral involvement, especially of lungs, oesophagus, kidneys and heart. It may be accompanied by calcinosis, raynaud's phenomenon, and telangiectasis (crest syndrome). It includes acrosclerosis and sclerodactyly. (12 Dec 1998) |
| systemic | <anatomy> Pertaining to or affecting the body as a whole. (18 Nov 1997) |
| systemic anaphylaxis | The immediate response, involving smooth muscles and capillaries throughout the body of a sensitised individual, that follows intravenous (and occasionally intracutaneous) injection of antigen (allergen). See: anaphylactic shock. Synonym: systemic anaphylaxis. (05 Mar 2000) |
| systemic anatomy | Anatomy of the systems of the body; an approach to anatomical study organised by organ systems, e.g., the cardiovascular system, emphasizing an overview of the system throughout the body; distinguished from regional anatomy. (05 Mar 2000) |
| systemic autoimmune diseases | A group of connective tissue disease's characterised by the presence of autoantibodies responsible for immunopathologically mediated tissue lesions; systemic lupus erythematosus is the prototype. (05 Mar 2000) |
| systemic blastomycosis | Infection with Blastomyces dermatitidis extending beyond the skin or the lung, the usual portals of entry; involvement of bone and genitourinary tract (especially. Prostate and epididymis) are most frequent. (05 Mar 2000) |
| systemic chondromalacia | A degenerative disease of cartilage producing a bizarre form of arthritis, with collapse of the ears, the cartilaginous portion of the nose, and the tracheobronchial tree; death may occur from chronic infection or suffocation because of loss of stability in the tracheobronchial tree of autosomal origin. Synonym: chronic atrophic polychondritis, generalised chondromalacia, Meyenburg's disease, Meyenburg-Altherr-Uehlinger syndrome, relapsing perichondritis, systemic chondromalacia, von Meyenburg's disease. (05 Mar 2000) |
| systemic circulation | The circulation of blood through the arteries, capillaries, and veins of the general system, from the left ventricle to the right atrium. Synonym: greater circulation. (05 Mar 2000) |
