A short systematic review was undertaken to assess whether adult patients presenting to the ED with a first seizure require a CT head scan to rule out emergent intracranial pathology. MEDLINE, EMBASE, Cochrane and Google Scholar databases were searched. ⋯ Our results indicate that adults presenting with a first seizure are a high-yield group for CT with a number needed to scan (NNS) between 10 and 19 for findings that would change management in ED, such as haemorrhage, infarction and tumours. We believe that this NNS is sufficiently low to justify the routine use of neuroimaging for these patients in emergency care.

Electronic patient records (EPRs) are potentially valuable sources of data for service development or research but often contain large amounts of missing data. Using complete case analysis or imputation of missing data seem like simple solutions, and are increasingly easy to perform in software packages, but can easily distort data and give misleading results if used without an understanding of missingness. So, knowing about patterns of missingness, and when to get expert data science (data engineering and analytics) help, will be a fundamental future skill for emergency physicians. This will maximise the good and minimise the harm of the easy availability of large patient datasets created by the introduction of EPRs.

Limited access to antivenoms is a global challenge in treating snakebite envenoming. In emergency situations where non-expired antivenoms are not readily available, expired antivenoms may be used to save lives with the risk of deteriorating quality, efficacy and safety. Therefore, we aimed to systematically review and summarise the sparse preclinical evidence of neutralising efficacy of expired antivenoms and real-world experience of using expired antivenoms in humans. ⋯ Even though the quality and efficacy of expired antivenoms are comparable to non-expired antivenoms in preclinical studies, the information is limited in terms of real-world experiences of using expired antivenoms and their safety. Therefore, the use of expired antivenoms may be generally inconclusive due to scarce data. Further investigations may be needed to support the extension of antivenoms' expiration date according to their potential efficacy after expiration.
