Uræmia.

Uræmia. When excretion of waste products from the body by the kidneys is defective, particularly therefore in cases of Bright's disease (see under KIDNEYS), peculiar symptoms, mostly cerebral, are met with, which are commonly called uræmic. Among the most characteristic are fits like epileptic seizures, delirium, tremors or spasms of muscles, transient attacks of blindness, dyspnoea, itching, vomiting. It is as yet uncertain whether it is to the urea (as implied by the name) or to others of the retained effete materials that these symptoms are due, which, though not infrequently recovered from, are always cause for grave anxiety.
