The cumulative Civil War hospital gangrene mortality was 45 percent . Goldsmith's method, which he applied to over 330 cases, yielded a mortality under 3 percent ." Goldsmith advocated the use of debridement and topical and injected bromide solutions on infected wounds to reduce the incidence and virulence of "poisoned miasma ." Copies of his book were issued to Union surgeons to encourage the use of his methods . </P> <P> The etymology of gangrene derives from the Latin word gangraena and from the Greek gangraina (γάγγραινα), which means "putrefaction of tissues". It has no etymological connection with the word green, despite the affected areas turning black, green, or yellowish brown . It is coincidence that, in Lowland Scots, the words "gang green" (go green) can be said to be an eggcorn for gangrene, as it describes the symptoms of the affliction . </P>

Where is gangrene most commonly found in the world
