Ciao is used often by Brazilians (who, for those who don't remember the historical bit about the "Line of Demarcation", speak Portuguese). Saude - is pronounced SOW-OO-GEE with an accent on the second syllable. (It always sort of reminds me of the vocalization of the sound of old car horns.) This means "health" (the "to your" is implied but normally not voiced) and is a common toast.
