An autopsy approach to bee sting-related deaths.

Although severe reactions to the sting of the common honey bee (Apis mellifera) are a common problem in Australia, reported deaths are uncommon, with the estimated mortality varying from one to four persons each year. The following study presents the postmortem findings in three cases of bee sting fatality, including one in which no observable sting was found. An autopsy approach to such cases is detailed. Overreporting of bee sting-related deaths may occur due to the inclusion of deaths unrelated to a reaction to bee venom, while under-reporting may be due to unexplained deaths where a history of a bee sting is not available or apparent at autopsy. A classification of bee sting-related deaths is proposed, which would allow more accurate reporting of bee sting-related fatalies. A serum tryptase and specific IgE to bee venom on serum obtained at autopsy can assist in confirming anaphylactic reaction to bee venom as the cause of death, particularly in the absence of observable stings. Although there are limitations to the usefulness of serum tryptase tests in the postmortem situation, it may still be useful to confirm suspected anaphylaxis in autopsy cases with an undetermined cause of death.
