| progressive vaccinia | A severe or even fatal form of vaccinia occurring chiefly in subjects with an immunologic deficiency or dyscrasia and characterised by progressive enlargement of the initial and also of secondary lesions. Synonym: vaccinia gangrenosa. (05 Mar 2000) |

| hereditary progressive arthro-ophthalmopathy | Autosomal dominant arthro-ophthalmopathy associated with progressive multiple dysplasia of the epiphyses, overtubulation of long bones, cleft lip and palate, hypermobility of joints, flattened vertebral bodies, pelvic bone deformities, and deafness. Synonym: Stickler's syndrome. (05 Mar 2000) |
| supranuclear palsy, progressive | A progressive neurological disease usually of the fifth decade characterised by supranuclear ophthalmoplegia especially paralysis of downward gaze, pseudobulbar palsy, gait disturbance, dysathria, truncal dystonia, memory and personality deterioration, and dementia. (12 Dec 1998) |
| diaphyseal dysplasia, progressive | Progressive thickening of diaphyseal cortex of long bones. (12 Dec 1998) |
| infantile progressive spinal muscular atrophy | Transmitted as autosomal recessive on chromosome 5q. Progressive dysfunction of the anterior horn cells in the spinal cord and brainstem cranial nerves with profound weakness and bulbar dysfunction occurring in the first two years of life. Three groups, based on age of clinical onset, are recognised. Synonym: familial spinal muscular atrophy, Hoffmann's muscular atrophy, infantile muscular atrophy, infantile progressive spinal muscular atrophy, progressive infantile spinal muscular atrophy, Werdnig-Hoffmann disease, Werdnig-Hoffmann muscular atrophy. (05 Mar 2000) |
| ophthalmoplegia, chronic progressive external | One of the mitochondrial encephalomyopathies characterised by slowly progressive paralysis of the extraocular muscles. Muscle biopsies disclose the characteristic ragged red fibres and large numbers of mitochondria with deleted DNA. (12 Dec 1998) |
| ovine progressive pneumonia | A chronic, progressive, contagious interstitial pneumonitis of sheep in Europe and the U.S. Caused by a "slow virus" (family Lentiviridae); it is now believed that maedi and visna are two histopathological and clinical manifestations of the same viral infection. Synonym: ovine progressive pneumonia. Origin: Icelandic, dyspnea (05 Mar 2000) |
| traumatic progressive encephalopathy | A chronic progressive brain damage resulting from multiple brain injuries, e.g., dementia pugilistica. (05 Mar 2000) |
| essential progressive atrophy of iris | Progressive atrophy of the iris without inflammatory signs, characterised by patchy loss of all layers of the iris with hole formation, migration of the pupil, degeneration of the corneal endothelium, peripheral anterior synechiae, and secondary glaucoma; usually unilateral, predominantly affecting women in their middle years. (05 Mar 2000) |
| leukoencephalopathy, progressive multifocal | Rare demyelinating disease of the central nervous system which develops in immunocompromised patients secondary to lymphoproliferative disease, immunosuppressive therapy, autoimmune disorders, or aids. It is caused by the jc virus, a polyomavirus. (12 Dec 1998) |
| adipose degeneration | Abnormal formation of microscopically visible droplets of fat in the cytoplasm of cells, as a result of injury. Synonym: adipose degeneration, steatosis. (05 Mar 2000) |
| adiposogenital degeneration | A disorder characterised primarily by obesity and hypogonadotrophic hypogonadism in adolescent boys; dwarfism is rare, and when present is thought to reflect hypothyroidism. Visual loss, behavioural abnormalities, and diabetes insipidus may occur. Frohlich's syndrome often is used synonymously for this disorder, although the original case involved a pituitary tumour; most cases are thought to result from hypothalamic dysfunction in areas regulating appetite and gonadal development. The most common causes are pituitary and hypothalamic neoplasms. Synonym: adiposis orchica, adiposogenital degeneration, adiposogenital dystrophy, adiposogenital syndrome, hypophysial syndrome, hypothalamic obesity with hypogonadism. Origin: L. Fr. G. Dys-, bad, + trophe, nourishment (05 Mar 2000) |
| age-related macular degeneration | A common macular degeneration beginning with drusen of the macula and pigment disruption and sometimes leading to severe loss of central vision. (05 Mar 2000) |
| albuminous degeneration | An obsolete terms for cloudy swelling. (05 Mar 2000) |
| amyloid degeneration | Infiltration of amyloid between cells and fibres of tissues and organs. Synonym: waxy degeneration. (05 Mar 2000) |
