A good trivia or crossword item. A Greek word meaning "a dwindling or wasting away." Pronounced "thi-sis." The tongue-twisting name "nephronophthisis" is derived from "nephron" + "phthisis." The nephron is the fundamental functional unit in the kidney and includes the renal tubule and glomerulus. In nephronophthisis the kidney is progressively destroyed and the child wastes away. Phthisis is an archaic name for tuberculosis. A person afflicted with tuberculosis in the old days was destined to dwindle and waste away like Mimi, the heroine of Puccini's 1896 opera "La Bohčme."
