| 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.

| 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) |
