Podcast #408: Go the hell to sleep

Author: Don Stader, MD

Educational Pearls:

  • Recent study showed efficacy 5mg IM midazolam > 10mg IM olanzapine > 10mg IM haloperidol for quickly sedating an agitated patient
  • If you have access, ketamine intravenous is the fastest
  • Olanzapine should be used with caution in elderly patients because of its anticholinergic properties
  • Ketamine can transiently worsen psychosis in some mental illness
  • Haloperidol is contraindicated in patients with prolonged QT
  • Olanzapine can be safely given intravenous as another option to your sedating arsenal

Podcast #314: Psychogenic nonepileptic seizures (PNES)

Author: Gretchen Hinson, M.D.

Educational Pearls:

  • PNES vs. epilepsy: postictal state is diagnostic of an epileptic seizure (sonorous respirations and/or confusion, lasting typically 20-30 minutes); Epileptiform seizures show decrease in convulsion frequency, but increase in convulsion amplitude while PNES convulsions demonstrate episodic convulsion amplitudes; and epileptiform seizures usually do not pause.
  • PNES is a form of conversion disorder and can be associated with underlying personality disorder; however there are patients with epilepsy that also can have PNES which complicates the diagnosis and treatment.
  • Patients that are malingering may have flailing movements and might talk during the episodes – both not typical of epileptic seizures or PNES.
  • Treatment for PNES is with psychotropic medications and psychotherapy as opposed to antiepileptic medications

Podcast #304: Nostalgia

Author: Dylan Luyten, MD

Educational Pearls

  • Johannes Hoffer coined term Nostalgia in 1688 in his medical dissertation.

 

  • Nostalgia was a formal medical diagnosis, and one that dates back to 17th century when soldiers had longing for home and melancholy with a constellation of symptoms including lethargy, sadness, disturbed sleep, heart palpitations, GI complaints, and/or skin findings for which the only cure was to return home.

 

  • In the civil war, over 5000 soldiers were given medical leave for nostalgia.
  • Always remember to view your patient in the appropriate context (psychosocial, cultural, historical, etc.)
