We thank Brumbraugh and colleagues for their interest in our article. We reported an increase in the total number of disc battery ingestions between 1998 and 2006 according to the American Association of Poison Control Centers (AAPCC).1 Litovitz et al2 failed to demonstrate a consistent increase using a different measure: the number of battery ingestions per million population, also based on data from the AAPCC. Unfortunately, both measures reflect information provided to 61 poison centers from voluntary reports by the public or health care professionals. The AAPCC is not able to completely verify the accuracy of every report, and many exposures may go unreported.2 Nevertheless, the more than 3000 reported battery ingestions in 2008 represent a significant health care problem, and the associated severe esophageal injuries were the impetus of our study.
