Do we need labs or a head CT after simple febrile or unprovoked seizures?

Labs or CT scans are not necessary to provide additional diagnostic information or reassurance for most children who recover completely following simple febrile seizures or unprovoked first time generalized seizures. The rate of abnormalities on these studies is very low, and the cost and downsides are too high to justify ordering them on a regular basis.

This podcast episode is designed to disseminate the important work of Choosing Wisely, an initiative of the the American Board of Internal Medicine Foundation, the goal of which is the spark conversations between clinicians and patients about what tests, treatments, and procedures are needed – and which ones are not.

The Choosing Wisely recommendation: Do not order laboratory testing or a CT scan of the head for a patient with an unprovoked, generalized seizure or a simple febrile seizure who has returned to baseline mental status

Stroke in Adults

Yes, PEM Currents is a Pediatric Emergency Medicine podcast, but during the COVID-19 pandemic we may be tasked with seeing patients outside of our area of expertise. Plus, there’s a lot we can learn from big people that we can extrapolate to children. I have partnered with POPCoRN, the Pediatric Overflow Planning Contingency Response Network to deliver content that will benefit those of us who may have been asked to care for adults both in their native habitat, and in our pediatric facilities. Marie Pfarr, a Hospital Medicine physician from Cincinnati Children’s delivers some timely content on stroke in adults in this brief, focused episode.

Status Epilepticus

Status epilepticus can be very stressful in the Pediatric Emergency Department. This episode of PEM Currents: The Pediatric Emergency Medicine Podcast focuses on management, and will guide you through the treatment process, starting with benzodiazepines, followed by a discussion of the recent evidence for second line therapy between fosphenytoin, levetiracetam, and valproate.
