| entrapment neuropathy | A focal nerve lesion produced by constriction or mechanical distortion of the nerve, within a fibrous or fibro-osseous tunnel, or by a fibrous band; with these lesions, stretching and angulation of the nerve may be as important a source of injury as compression; entrapment neuropathies tend to occur at particular sites in the body.

| familial amyloid neuropathy | <neurology> A disorder in which various peripheral nerves are infiltrated with amyloid and their functions disturbed, an abnormal prealbumin is also formed and is present in the blood; characteristically, it begins during mid-life and is found largely in persons of Portuguese descent. Other rare clinical types occur. Inheritance: autosomal dominant. Synonym: familial amyloidosis, hereditary amyloidosis. (05 Mar 2000) |
| lead neuropathy | A peripheral neuropathy reportedly seen in chronic lead intoxication; reputedly characterised by wrist-drop, but no convincing modern reports of this are available. (05 Mar 2000) |
| leprous neuropathy | A slowly developing granulomatous neuropathy, commonly seen in leprosy, caused by Mycobacterium leprae. (05 Mar 2000) |
| aphasia, primary progressive | A type of aphasia appearing gradually and gradually worsening without any major change in other cognitive functions. It is regarded by some authors as a syndrome which may be due to various degenerative diseases of the cerebral cortex (notably alzheimer disease, owing to its frequency), while others see in it an autonomous disease related to a neuropathological process that is distinct from the main degenerative dementias. The principal clinical peculiarity of primary progressive aphasia is that it spares the patient's autonomy for a long time, but ultimately turns into global dementia. (12 Dec 1998) |
| bovine progressive degenerative myeloencephalopathy | A familiar myeloencephalopathy of brown Swiss cattle characterised by bilateral hindleg weakness and ataxia and deficient proprioceptive reflexes. (05 Mar 2000) |
| rapidly progressive glomerulonephritis | <nephrology> A relatively uncommon (affecting 1 out of 10,000 people) form of acute glomerulonephritis that results in damage within the glomerulus of the kidney. There is rapid loss of kidney function with the formation of crescents on microscopic analysis (kidney biopsy). This disorder may result in acute glomerulonephritis or nephrotic syndrome, but ultimately results in renal failure and end-stage renal disease. Symptoms include smoky coloured urine (pyuria), decreased urine output, swelling and hypertension. Any conditions which can cause a vasculitis increase the risk of this disorder. Some examples include lupus, Goodpasture's syndrome, Henoch-Schonlein purpura, IgA nephropathy, membranoproliferative glomerulonephritis, anti-glomerular basement membrane antibody disease, history for malignant tumours and exposure to hydrocarbon solvents.

| chronic progressive chorea | A progressive disorder usually beginning in young to middle age, consisting of a triad of choreoathetosis, dementia, and autosomal dominant inheritance with complete penetrance. Bilateral marked wasting of the putamen and the head of the caudate nucleus is characteristic. Synonym: chronic progressive chorea, degenerative chorea, hereditary chorea, Huntington's disease. (05 Mar 2000) |
| chronic progressive external ophthalmoplegia | A specific type of slowly worsening weakness of the ocular muscles, usually associated with a pigmentary retinopathy. See: Kearns-Sayre syndrome, oculopharyngeal dystrophy. Synonym: ocular myopathy. (05 Mar 2000) |
| chronic progressive syphilitic meningoencephalitis | Syphilitic infection manifested as dementia (often with delusional features), dysarthria, seizures, myoclonic jerks, action tremor, impaired walking and standing, pupillary abnormalities, and abnormal CSF findings. Synonym: chronic progressive syphilitic meningoencephalitis. (05 Mar 2000) |
| pneumonia, progressive interstitial, of sheep | Chronic respiratory disease caused by the visna-maedi virus. It was formerly believed to be identical with jaagsiekte (pulmonary adenomatosis, ovine) but is now recognised as a separate entity. (12 Dec 1998) |
| primary progressive cerebellar degeneration | A familial ataxic condition related to cerebellar degeneration. (05 Mar 2000) |
| progressive | Advancing, going forward, going from bad to worse, increasing in scope or severity. (18 Nov 1997) |
| progressive bacterial synergistic gangrene | Undermining ulcer of the skin and subcutaneous tissues, usually following an operation, caused by a synergistic interaction between microaerophilic nonhemolytic streptococci and aerobic haemolytic staphylococci. Synonym: Meleney's gangrene, progressive bacterial synergistic gangrene. (05 Mar 2000) |
| progressive bulbar palsy | One of the subgroups of motor neuron disease; a progressive degenerative disorder of the motor neurons of primarily the brainstem, manifested as weakness (and wasting) of the various bulbar muscles, resulting in dysarthria and dysphagia-fluid regurgitation is an outstanding symptom and can cause aspiration; tongue weakness and wasting is usually evident, and often the fasciculation potentials are present in the tongue and facial muscles. Synonym: glossopalatolabial paralysis, glossopharyngeolabial paralysis. (05 Mar 2000) |
