| erythrokeratoderma variabilis | A dermatosis characterised by hyperkeratotic plaques of bizarre, geographic configuration, associated with erythrodermic areas that may vary remarkably in size, shape, and position from day to day; onset is usually in the first year of life; autosomal dominant inheritance. Synonym: keratosis rubra figurata. (05 Mar 2000) |

| radially symmetrical | Said of an organism or organ which can be cut through the centre into equal and similar parts along two or more planes, actinomorphic. (09 Oct 1997) |
| conjoined symmetrical twins | Conjoined twin's in which both members are approximately of the same size, and nearly normal except for the areas of fusion. Synonym: conjoined symmetrical twins. (05 Mar 2000) |
| symmetrical | 1. Involving or exhibiting symmetry; proportional in parts; having its parts in due proportion as to dimensions; as, a symmetrical body or building. 2. <biology> Having the organs or parts of one side correspponding with those of the other; having the parts in two or more series of organs the same in number; exhibiting a symmetry.See Symmetry. 3. <botany> Having an equal number of parts in the successive circles of floral organs; said of flowers. Having a likeness in the form and size of floral organs of the same kind; regular. 4. <mathematics> Having a common measure; commensurable. Having corresponding parts or relations. A curve or a plane figure is symmetrical with respect to a given line, and a line, surface, or solid with respect to a plane, when for each point on one side of the line or plane there is a corresponding point on the other side, so situated that the line joining the two corresponding points is perpendicular to the line or plane and is bisectad by it. Two solids are symmetrical when they are so situate dwith the respect to an intervening plane that the several points of their surfaces thus correspond to each other in position and distance. In analysis, an expression is symmetrical with respect to several letters when any two of them may change places without affecting the expression; as, the expression a^2b + ab^2 + a^2c + ac^2 + b^2c + bc^2, is symmetrical with respect to the letters a, b, c. Symmet"rically, Symmet"ricalness. Origin: Cf. F. Symetrique. See Symmetry. Source: Websters Dictionary (01 Mar 1998) |
| symmetrical gangrene | Gangrene affecting the extremities of both sides of the body; it is seen particularly in severe arteriosclerosis, myocardial infarction, and ball-valve thrombus. (05 Mar 2000) |
| extinction symmetrical | <microscopy> Vibration directions bisecting a prominent crystal profile angle. (05 Aug 1998) |
| lipomatosis, multiple symmetrical | Multiple circumscribed or encapsulated lipomas which may be distributed symmetrically or haphazardly or which may form a collar around the neck. (12 Dec 1998) |
| 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. (27 Sep 1997) |
| 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) |
