| subacute combined degeneration of the spinal cord | A subacute or chronic disorder of the spinal cord, such as that occurring in certain patients with vitamin B12 deficiency, characterised by a slight to moderate degree of gliosis in association with spongiform degeneration of the posterior and lateral columns. Synonym: combined sclerosis, combined system disease, funicular myelitis, Putnam-Dana syndrome, vitamin B12 neuropathy. (05 Mar 2000) |
|---|---|
| subacute glomerulonephritis | Undesirable term for glomerulonephritis with proteinuria, haematuria and azotemia persisting for many weeks; renal changes are variable, including those of rapidly progressive and membranoproliferative glomerulonephritis. Synonym: subacute nephritis. (05 Mar 2000) |
| subacute granulomatous thyroiditis | Thyroiditis with round cell (usually lymphocytes) infiltration, destruction of thyroid cells, epithelial giant cell proliferation, and evidence of regeneration; thought by some to be a reflection of a systemic infection and not an example of true chronic thyroiditis. Synonym: de Quervain's thyroiditis, giant cell thyroiditis. (05 Mar 2000) |
| subacute hepatitis | <pathology> This is a form of continuing liver inflammation that results in liver cell death. Causes include viral infection (hepatitis D, hepatitis B, hepatitis C), autoimmune disease, drug ingestion or metabolic causes. Chronic active hepatitis will lead to hepatic failure and death in a small percentage of these patients. (27 Sep 1997) |
| subacute inclusion body encephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
| subacute inflammation | An inflammation that is intermediate in duration between that of an acute inflammation and that of a chronic inflammation, usually persisting longer than 3 or 4 weeks. (05 Mar 2000) |
| subacute lymphocyte thyroiditis | A subacute variant of Hashimoto's thyroiditis. (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) |
| subacute nephritis | Undesirable term for glomerulonephritis with proteinuria, haematuria and azotemia persisting for many weeks; renal changes are variable, including those of rapidly progressive and membranoproliferative glomerulonephritis. Synonym: subacute nephritis. (05 Mar 2000) |
| subacute rheumatism | A mild but usually protracted form of acute rheumatic fever, often resistant to treatment. (05 Mar 2000) |
| subacute sclerosing leukoencephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
| subacute sclerosing panencephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
| subacute spongiform encephalopathy | A form of spongiform encephalopathy that is associated with a "slow virus", which to date has not been adequately described, is transmissible, and has a rapidly progressive, fatal course; e.g., Creutzfeldt-Jakob disease, kuru, Gerstmann-Straussler syndrome, scrapie. (05 Mar 2000) |
| thyroiditis, subacute | Inflammation of the thyroid gland after a viral illness. (12 Dec 1998) |
