| 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) |
| progressive infantile 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) |
| progressive lipodystrophy | A condition characterised by a complete loss of the subcutaneous fat of the upper part of the torso, the arms, neck, and face, sometimes with an increase of fat in the tissues about and below the pelvis. Synonym: Barraquer's disease, lipodystrophia progessiva superior, partial lipoatrophy, Simons' disease. (05 Mar 2000) |
| progressive massive fibrosis | <radiology> Progressive massive fibrosis, silicosis (properly conglomerate nodules, not progressive massive fibrosis), coal worker's pneumoconiosis, density (conglomerate mass) in upper lobe, retracts toward hilum, leaves emphysematous change (bullae) at lung periphery (12 Dec 1998) |
| progressive multifocal leukoencephalopathy | <radiology> Demyelinating disease due to papovavirus, seen in immunosuppressed hosts: lymphoma, leukaemia, AIDS, TB, sarcoidosis, organ transplant, most prominent in pareito-occipital white matter, NO contrast enhancement (12 Dec 1998) |
| progressive muscle relaxation | A cognitive-behavioural strategy in which muscles are alternately tensed and then relaxed in a systematic fashion. (16 Dec 1997) |
| progressive muscular atrophy | A serious neurologic disease that results from the progressive degeneration of the motor neurons. (27 Sep 1997) |
| progressive muscular dystrophy | A form of progressive muscular atrophy in which the disease begins in the muscle and not in the spinal centres. Synonym: Erb atrophy, idiopathic muscular atrophy. (05 Mar 2000) |
| progressive patient care | Organization of medical and nursing care according to the degree of illness and care requirements in the hospital. The elements are intensive care, intermediate care, self-care, long-term care, and organised home care. (12 Dec 1998) |
| progressive pigmentary dermatosis | Chronic purpura, especially of the legs in men, spreading to form brownish patches; associated microscopically with perivascular lymphatic infiltration, diapedesis, and haemosiderosis. Synonym: Schamberg's dermatitis. (05 Mar 2000) |
| progressive processes | Process's that continue after they no longer serve the needs of the organism, and after cessation of the stimulus that evoked the process. (05 Mar 2000) |
| progressive spinal amyotrophy | A serious neurologic disease that results from the progressive degeneration of the motor neurons. (27 Sep 1997) |
| progressive spinal muscular atrophy | One of the subgroups of motor neuron disease; a progressive degenerative disorder of the motor neurons of the spinal cord, manifested as progressive, often symmetrical, weakness and wasting, typically beginning in the distal portions of the limbs, particularly in the upper extremities, and spreading proximally; fasciculation potentials are often present, but evidence of corticospinal tract disease (e.g., increased deep tendon reflexes, Babinski sign) is not.
