nephritis

(nef-ri’tis), pl. nephrit'ides [Gr. νεφρός Tiasey ἘΞ -eres inflammation]. I ation of the kidney. acute n., suppurative nephritis wit a short and severe course, constituting the acute form of Bright's disease. There are two forms: acule parenchymatous n. and acute diffuse n., caused by exposure to wet and cold, or by pneumonia or pregnancy, or resulting from scarlet fever or other exanthemata. The kidney becomes soft and enlarged, with fatty degeneration of the tubular epithelium and the formation of tube-casts. It is attended with pain in the lumbar region, fever, dropsy, frequent and painful urination, with presence of casts and of blood in the urine. albuminous n., nephritis in which albuminuria occurs. bacterial n., nephritis which is caused by microérganisms. capsular n., that which specially affects Bowman’s capsules. catarrhal n., nephritis in which the pyramids are of a reddish hue, from the plugging of the tubular canals with cells. cheesy n., a chronic suppurative form with’ Caseous deposits. chronic n., any variety having a relatively slow course. clostridial n., chronic nephritis believed to be due to the presence of clostridia. It is characterized by nervousne , sleeple ne , dyspnea, dyspepsia, and _albuminuria. croupous Ώ. Sameasaculen. desquamativen., acute catarrhal nephritis. diffuse n., nephritis affecting both the parenchyma and the stroma. iffuse n., acute. See under acule n. diffuse n., chronic, a form resulting from acute nephritis or from alcohol and lead-poisoning, or from gout. The kidney becomes small, cystic, nodulated, and adherent to its capsule. The interstitial ti ue is increased, and there is thickening of the ve el-walls and of the malpighian corpuscles: the heart becomes hypertrophied, and the walls of the small arteries thickened; the malpighian tubules contain hyaline casts. The disease is attended with progre ive lo of strength, edema about the eyelids, dyspnea, headache, dyspepsia, diarrhea, and the frequent pa age of large quantities of light-colored urine containing albumin and casts. Called also chronic int erst ilial n., atrophic kidney, contracted kidney, gouty kidney, and granular kidney. exudative n., nephritis with exudation of the blood-serum. fibrous n., that which specially affects the stroma. glomerular n., that which principally affects the glomeruli. glomerulocap- 8 n., a form which primarily affects the glomeruli and Bowman’s capsules. hypo genetic D., nephritis due to an unusual strain upon kidneys that are congenitally underdeveloped. idiopathic n., nephritis the cause of which is not discoverable. indurative n., chronic nephritis with atrophy of the secreting parts of the kidney and hypertrophy of the connective-ti ue stroma. interstitial m. Same as fibrous n. Lancer eaux’s n., interstitial nephritis of rheumatic origin. parenchymatous n., nephritis which spccially affects the parenchyma of the kidney. parenc to us n., acute. Sce under acuts 7. parenchymatous n., chronic, is marked by changes similar to those of the acute form, without congestion. The kidney becomes soft and white, and the disease is attended by anemia, dropsy, anasarca, gastro-intestinal disorder, and dyspnea, with secretion of small amounts of high. colored urine containing albumin and casts. Called also chronic tubal n., large white kidney, and broany kidney. productive n., nephritis with the development of serous exudate and hypertrophy of the connective-ti ue stroma. saturnine n., a form due to chronic lead-poisoning. scarlatinal Ὡ., acute nephritis due to scarlet fever. suppurative n., a form accompanied by absce of the kidney. suppurative n., acute, is due to septic infection, generally from operations on the genito-urinary tract (then called surgical kidney), and marked by the development of multiple absce es. sup- 630
