| necrotizing encephalopathy | Subacute encephalomyelopathy affecting infants, causing dementia, spasticity, and optic atrophy; autosomal recessive inheritance. Synonym: necrotizing encephalomyelopathy, necrotizing encephalopathy. (05 Mar 2000) |
|---|---|
| necrotizing enterocolitis | <radiology> NEC, pneumatosis intestinalis, submucosal: initial finding, mult. Cystic lucencies; looks like stool (!), subserosal: linear lucencies, portal vein: with or without transient; not significant, aetiology: preemie, perinatal stress, intestinal ischemia, survivors may develop intestinal strictures (12 Dec 1998) |
| necrotizing fasciitis | A rare soft-tissue infection primarily involving the superficial fascia and resulting in extensive undermining of surrounding tissues; progress is often fulminant and may involve all soft-tissue components, including the skin; usually occurs postoperatively, after minor trauma, or after inadequate care of abscesses or cutaneous ulcers. See: group A streptococcal necrotizing fasciitis. (05 Mar 2000) |
| necrotizing papillitis | <nephrology> Necrosis of renal papillae, occurring in acute pyelonephritis, especially in diabetics, or in analgesic nephropathy; renal failure may result. Synonym: necrotizing papillitis. (05 Mar 2000) |
| necrotizing scleritis | Fibrinoid degeneration and necrosis of the sclera. (05 Mar 2000) |
| necrotizing ulcerative gingivitis | An acute or recurrent gingivitis of young and middle-aged adults characterised clinically by gingival erythema and pain, fetid odour, and necrosis and sloughing of interdental papillae and marginal gingiva which gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are felt to play a significant but poorly defined role in the pathogenesis. Synonym: fusospirochetal gingivitis, trench mouth, ulceromembranous gingivitis, Vincent's disease, Vincent's infection. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| 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) |
| arthritis-encephalitis virus, caprine | A species of lentivirus, subgenus ovine-caprine lentiviruses (lentiviruses, ovine-caprine), closely related to visna-maedi virus and causing acute encephalomyelitis, chronic arthritis, pneumonia, mastitis, and glomerulonephritis in goats. It is transmitted mainly in the colostrum and milk. (12 Dec 1998) |
| Australian X encephalitis | A severe encephalitis with a high mortality rate occurring in the Murray Valley of Australia; the disease is most severe in children and is characterised by headache, fever, malaise, drowsiness or convulsions, and rigidity of the neck; extensive brain damage may result; it is caused by the Murray Valley encephalitis virus (genus Flavivirus). Synonym: Australian X disease, Australian X encephalitis. (05 Mar 2000) |
| bacterial encephalitis | Encephalitis of bacterial aetiology. Synonym: encephalitis pyogenica, purulent encephalitis, suppurative encephalitis. (05 Mar 2000) |
| bovine spongiform encephalitis | <pathology> A neuro-degenerative disease found in domestic cattle which is related to a number of other similar diseases found in other animal species, including humans. The most well-known of these other diseases are scrapie, found in sheep, and Creutzfeldt-Jakob Disease, found in humans. The family of diseases is caused by an abnormally-configured protein called a prion. The function of the protein in its normal configuration is not certain. The diseases are similar to Alzheimer's disease in humans, except the progressive loss of brain function is more rapid. (09 Oct 1997) |
| bunyavirus encephalitis | Encephalitis of abrupt onset, with severe frontal headache and low-grade to moderate fever, caused by members of the genus Bunyavirus (Bunyaviridae family); infections also occur in rodents, lagomorphs, and domestic animals. Synonym: California encephalitis. (05 Mar 2000) |
