On page 935 in the 12 August 2010 issue, one of the affiliations of the third author (Valentina Pacciani) is incorrect. The second affiliation listed as “Department of Pediatrics, Università di Tor Vergata, Rome” should have been: “University Department of Pediatrics (DPUO), Bambino Gesù Children's Hospital, Rome, Italy.” The correct byline and affiliations are shown. The error has been corrected in the online version, which now differs from the print version.
