Medical researchers at Rome's Cattolica University report that Italian opera singers in Rome may be more susceptible than ordinary Italians to gastroesophageal reflux (otherwise known as acid reflux). Is this a problem unique to Rome, is my first question. The bucatini at the opera house cafeteria? The mozzarella in carrozza? More urgently, does this explain the utter chaos currently engulfing Rome Opera's Gheorghiu/soprano#2/soprano#3 sans Filianoti La Traviata ?
