(microsurgical epididymal sperm aspiration) the removal of spermatozoa from the epididymis by needle *aspiration. This procedure, performed under anaesthetic, may be undertaken to assist conception in cases where the normal passage of sperm from the testis is obstructed, for example by blockage (through infection) of the ducts or by vasectomy. The extracted sperm are subjected to special treatment to select the strongest and most motile; these are then chemically treated to activate them and used for in vitro fertilization (see ICSI).
(membranoproliferative glomerulonephritis) a renal disease characterized by changes in the glomeruli with mesangial cell proliferation and thickening of the capillary wall (see juxtaglomerular apparatus). Three types are distinguished. Type 1 is associated with immune deposits in the subendothelial space and the mesangial cells, and may sometimes be associated with cryoglobulinaemia (see cryoglobulin) and infection with the hepatitis C virus. Type 2, also known as dense deposit disease, is associated with a ribbon of electron-dense material within the glomerular basement membrane. Type 3 is associated with immune deposits in the subendothelium, the basement membrane, and the subepithelial spaces. All three types have a variable presentation, ranging from asymptomatic abnormalities of the urinary sediment through *nephrotic syndrome to subacute renal failure. Apart from treatment of any coexisting hepatitis C, there is no consensus regarding specific treatment of these conditions.... mesangiocapillary glomerulonephritis
n. inflammation of the middle layer (media) of an artery, which is often combined with inflammation in all layers of the artery wall. It is seen in syphilis, polyarteritis, temporal arteritis, and Buerger’s disease.... mesarteritis
