| 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) |
| progressive bulbar paralysis | Progressive weakness and atrophy of the muscles of the tongue, lips, palate, pharynx, and larynx, usually occurring in later life; most often caused by motor neuron disease. Synonym: bulbar palsy, bulbar paralysis, Duchenne's disease, Erb disease, glossolabiolaryngeal paralysis, glossolabiopharyngeal paralysis. (05 Mar 2000) |
| progressive cataract | A cataract in which the opacification process progresses to involve the entire lens. (05 Mar 2000) |
| progressive cerebral poliodystrophy | Familial progressive spastic paresis of extremities with progressive mental deterioration, with development of seizures, blindness and deafness, beginning during the first year of life, and with destruction and disorganization of nerve cells of the cerebral cortex. Synonym: Alpers disease, Christensen-Krabbe disease, progressive cerebral poliodystrophy. (05 Mar 2000) |
| progressive choroidal atrophy | An x chromosome-linked abnormality characterised by atrophy of the choroid and degeneration of the retinal pigment epithelium causing night blindness. (12 Dec 1998) |
| progressive circumscribed cerebral atrophy | Circumscribed atrophy of the cerebral cortex. Synonym: lobar sclerosis, progressive circumscribed cerebral atrophy. (05 Mar 2000) |
| progressive cleavage | In fungi, a type of sporulation in which cleavage planes in the cytoplasm first produce protospores and then sporangiospores in a sporangium. (05 Mar 2000) |
| progressive emphysematous necrosis | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| progressive familial scleroderma | A syndrome characterised by calcinosis cutis, Raynaud's phenomenon, sclerodactyly, and telangiectasia; usually due to scleroderma; autosomal dominant form of progressive systemic sclerosis. (05 Mar 2000) |
| progressive hypertrophic polyneuropathy | A familial type of demyelinating sensorimotor polyneuropathy that begins in early childhood and is slowly progressive; clinically characterised by foot pain and paresthesias, followed by symmetrical weakness and wasting of the distal limbs; one of the causes of stork legs; patients are wheelchair bound at an early age; peripheral nerves are palpably enlarged and non-tender; pathologically, onion bulb formation is seen in the nerves: whorls of overlapping, intertwined Schwann cell processes that encircle bare axons; usually autosomal recessive inheritance. Synonym: Dejerine's disease, progressive hypertrophic polyneuropathy. (05 Mar 2000) |
