| proliferative retinopathy | <ophthalmology, pathology> A disease of the small blood vessels of the retina of the eye. See: diabetic retinopathy. Origin: Gr. Pathos = disease (09 Oct 1997) |
|---|---|
| diabetic retinopathy | <ophthalmology, pathology> A major cause of blindness in diabetics. Retinal disease results from adverse effects on the blood vessels which supply the retina. Swollen retinal vessels which leak fluid into the retina are commonly seen on physical examination of the eyes. Poorly controlled insulin dependent diabetes and/or hypertension are the major risk factors. Symptoms include decreased vision and colour perception. Origin: Gr. Pathos = disease (27 Sep 1997) |
| vitreoretinopathy, proliferative | Vitreoretinal membrane shrinkage or contraction secondary to the proliferation of primarily retinal pigment epithelial cells and glial cells, particularly fibrous astrocytes, followed by membrane formation. The formation of fibrillar collagen and cellular proliferation appear to be the basis for the contractile properties of the epiretinal and vitreous membranes. (12 Dec 1998) |
| mesangial proliferative glomerulonephritis | <nephrology, pathology> Inflammation of the kidney glomerulus (blood filtering portion of the kidney) due to the abnormal deposition of IgM antibody in the mesangium layer of the glomerular capillary. A form of glomerulonephritis that appears to be caused by an abnormal immune response. This disorder generally manifests as nephrotic syndrome. Symptoms include swelling, dark urine, weight gain, hypertension, anorexia and bloody urine. Acronym: MPGN (05 Jan 1998) |
| proliferative | Proliferous Increasing the numbers of similar forms. (05 Mar 2000) |
| proliferative arthritis | Rarely used term for rheumatoid arthritis, based on the characteristic proliferation of the synovial membrane seen in joints affected by the disease. (05 Mar 2000) |
| proliferative bronchiolitis | Bronchiolitis with obliteration of bronchiolar lumen and alveoli by epithelial proliferation, which may follow influenza and giant-cell pneumonia. (05 Mar 2000) |
| proliferative choroiditis | The dense scar tissue produced by severe choroiditis. (05 Mar 2000) |
| proliferative dermatitis | An infectious exudative dermatitis of cattle, sheep, goats, horses, and other animals (occasionally man) caused by Dermatophilus congolensis; severe (sometimes fatal) dermatophilosis is seen in cattle in the Caribbean, invariable in association with Amblyomma variegatum infestations. Synonym: proliferative dermatitis, streptothrichosis, streptotrichiasis, streptotrichosis. (05 Mar 2000) |
| proliferative fasciitis | A benign rapidly-growing subcutaneous nodule characterised by proliferation of fibroblasts and basophilic giant cells slightly resembling ganglion cells. (05 Mar 2000) |
| proliferative gingivitis | Inflammatory changes in the gingiva characterised by proliferation of the gingival components. (05 Mar 2000) |
| proliferative glomerulonephritis | Glomerulonephritis with hypercellularity of glomeruli due to proliferation of endothelial or mesangial cells, occurring in acute glomerulonephritis and membranoproliferative glomerulonephritis. (05 Mar 2000) |
| proliferative inflammation | An inflammatory reaction in which the distinguishing feature is an actual increase in the number of tissue cells, especially the reticuloendothelial macrophages, in contrast to cells exuded from blood vessels; in addition, exudates of various types are likely to be observed in granulomas and other forms of proliferative inflammation, but the latter may occur without an exudate being formed (as in certain infections caused by virus). Synonym: hyperplastic inflammation. (05 Mar 2000) |
| proliferative myositis | A rapidly growing benign infiltrating fibrous nodule in skeletal muscle, containing characteristic giant cells resembling ganglion cells. (05 Mar 2000) |
| diabetic | Diabetes mellitus is a disorder that is caused by the insufficient production of the pancreatic hormone insulin. Without insulin cells are unable to absorb glucose, necessary for cellular metabolism and energy production. Patients may have type I diabetes (juvenile onset) or type II diabetes (adult onset). Individuals with either condition are considered to be diabetic. (27 Sep 1997) |
