I am writing this letter in reference to the paper titled “Cardiac arrhythmias and serum cardiac troponins in Vipera palaestinae envenomations in dogs” by Segev G., et al in J Vet Intern Med 2008;22:106–113. I appreciate the work that made this study possible, and I enjoyed reading it. If it were not for my great interest in venomous snake bites in dogs, I probably would not have detected the following accidental oversight. On the bottom of p. 106 and top of p. 107 the authors make reference to a 42–47% incidence of cardiac arrhythmias in dogs envenomated by the Eastern diamondback rattlesnake, Crotalus adamanteus, but their reference (10) is in error because I and my colleagues authored the papers that contain that particular information.1,2 The paper that is used as reference (10) describes serum troponin elevations in dogs with gastric dilatation-volvulus and chest trauma. We all make mistakes, but at the same time all authors should take every effort to quote the original source of scientific information. The original sources are provided should there be any interest by the JVIM readers.
