| 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. (05 Mar 2000) |
| progressive staining | A procedure in which staining is continued until the desired intensity of colouring of tissue elements is attained. (05 Mar 2000) |
| progressive subcortical encephalopathy | <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 supranuclear palsy | A disorder that is associated with nerve cell destruction and progressive lack of coordination, neck stiffness, trunk stiffness, problems with eye movement and mild dementia. Disorders that are similar include Alzheimer's disease, cerebellar dysfunction, Jakob-Creutzfeldt disease and Parkinson's disease. The cause for progressive supranuclear palsy is unknown, but is likely a degenerative nerve disorder that is somehow triggered by a viral infection. Pathologic changes include nerve cell damage and destruction of myelin sheath. There is no known cure. (27 Sep 1997) |
| progressive tapetochoroidal dystrophy | 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 torsion spasm | A genetic, environmental, or idiopathic disorder, usually beginning in childhood or adolescence, marked by muscular contractions that distort the spine, limbs, hips, and sometimes the cranial-innervated muscles. The abnormal movements are increased by excitement and, at least initially, abolished by sleep. The musculature is hypertonic when in action, hypotonic when at rest. Hereditary forms usually begin with involuntary posturing of the foot or hand (autosomal recessive form ) or of the neck or trunk (autosomal dominant form ); both forms may progress to produce contortions of the entire body. Synonym: progressive torsion spasm, torsion disease of childhood, torsion dystonia, Ziehen-Oppenheim disease. (05 Mar 2000) |
