| acute necrotizing haemorrhagic leukoencephalitis | A fulminating demyelinating disorder of the central nervous system that affects mainly children and young adults. Almost always preceded by a respiratory infection, characterised by the abrupt onset of fever, headache, confusion, and nuchal rigidity, soon followed by focal seizures, hemiplegia, or quadriplegia, brainstem findings, and coma; the CSF shows evidence of an inflammatory process; due to the massive destruction of the white matter of one or both hemispheres, often accompanied by similar destruction of the white matter of the brainstem and cerebellar peduncles; of unknown aetiology. Synonym: acute haemorrhagic leukoencephalitis, acute necrotizing haemorrhagic leukoencephalitis. (05 Mar 2000) |

| acute necrotizing myelitis | A spinal cord disorder, probably a demyelinating disease, which affects persons of all ages and either sex. Presents with abrupt or more gradual onset with sensory abnormalities and upper motor neuron weakness; soon a reflexic flaccid motor paralysis and sphincter paralysis supervenes, which is permanent. In some, but not all cases, bilateral or unilateral optic neuritis is associated. In the cerebrospinal fluid, the protein is increased, and mononuclear cells are present. After autopsy, the lesion has been identified as a necrotizing haemorrhagic leukomyelitis. (05 Mar 2000) |
| acute 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) |
| pancreatitis, acute necrotizing | Acute inflammation of the pancreas with areas of devitalised pancreatic and/or peripancreatic tissue. These necrotic areas may involve large areas of the pancreas or may be small. When a ct scan is performed with contrast media using a bolus technique, necrotic areas do not perfuse with media and are not enhanced. The lack of enhancement distinguishes necrotic tissue from the adjacent well-perfused viable pancreatic parenchyma. (12 Dec 1998) |
| gingivitis, necrotizing ulcerative | An acute or chronic gingival infection characterised by redness and swelling, necrosis extending from the interdental papillae along the gingival margins, pain, haemorrhage, necrotic odour, and often a pseudomembrane. The condition may extend to the oral mucosa, tongue, palate, or pharynx. (12 Dec 1998) |
| group A streptococcal necrotizing fasciitis | A complication of infection with GAS (group A streptococci) in which the bacteria attacks and destroys muscle tissue. According to the CDC, 5-10% of people with severe GAS infection develop necrotizing fasciitis. Though the infection can be treated with antibiotics, the fatality rate is close to 30%. This complication often develops as a wound infection after surgery or injury. (05 Mar 2000) |
| sialometaplasia, necrotizing | A benign, inflammatory, variably ulcerated, occasionally bilateral, self-healing lesion of the minor salivary glands that is often confused clinically and histologically with carcinoma. (12 Dec 1998) |
| necrotizing angiitis | Inflammatory reaction of blood vessels resulting in fibrinoid necrosis of tissue, especially of the blood vessel wall. (05 Mar 2000) |
| necrotizing arteriolitis | Necrosis in the media of arterioles, characteristic of malignant hypertension. Synonym: arteriolonecrosis. (05 Mar 2000) |
| necrotizing cellulitis | Synonym: gangrenous cellulitis. (05 Mar 2000) |
| necrotizing encephalitis | Any encephalitis in which extensive brain necrosis occurs, e.g., acute necrotizing haemorrhagic encephalomyelitis. (05 Mar 2000) |
| necrotizing encephalomyelopathy | Subacute encephalomyelopathy affecting infants, causing dementia, spasticity, and optic atrophy; autosomal recessive inheritance. Synonym: necrotizing encephalomyelopathy, necrotizing encephalopathy. (05 Mar 2000) |
| 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) |
