- 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

- 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

- 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.)
