Case Reports Observational Study
The LIMIT clinical decision instrument reduces neuroimaging compared to unstructured clinician judgement in recurrent seizures.
Given the many causes of seizures, emergency physicians often utilize brain computed tomography (CT) to evaluate for intracranial pathology. Previously, we have validated the LIMIT (Let's Image Malignancy, Intracranial Hemorrhage, and Trauma) clinical decision instrument (CDI) study to determine which patients with recurrent seizures require emergent neuroimaging. The LIMIT CDI had a negative predictive value (NPV) of 99.9%. Here, we seek to compare the LIMIT CDI to unstructured physician judgement. ⋯ When compared to unstructured physician judgement, the LIMIT CDI would have reduced brain CT usage by more than 13%. Although the LIMIT CDI needs to be validated in a larger set of patients, it performed better than unstructured physician judgement for evaluating need for emergent neuroimaging after recurrent seizures.

The aim of this study was to determine the level of serum NGRN in epilepsy patients presenting at the Emergency Department with complaints of an epileptic seizure, and to thus evaluate the utility of this biomarker in the differentiation of epilepsy and PNES patients from each other. ⋯ The differential diagnosis of ES from PNES remains a challenging situation for emergency service physicians. Based on the findings of this study, it can be said that the serum NRGN level is high in patients who have experienced an epileptic seizure. Therefore, this new biomarker can be considered for use in the differential diagnosis of epileptic seizure and PNES.

While there is ample data supporting the use of barbiturates and benzodiazepines (BZDs) for the treatment of alcohol withdrawal, there is a paucity of information on treating recurrent withdrawal among high healthcare utilizing patients. The purpose of this study was to assess the efficacy and safety of phenobarbital (PB), with or without adjuvant BZDs, for treatment of acute alcohol withdrawal in the emergency department (ED) in patients with high rates of recurrent withdrawal. ⋯ Among patients with multiple visits presenting with alcohol withdrawal, treatment with PB, BZDs, or both did not result in significantly different rates of admission or readmission within 48 h. Receiving a combination of PB and BZDs was associated with significantly longer ED length of stay, more ICU care, and increased incidence of hypotension as compared to either PB or a BZD alone.

Status Epilepticus is the most common non-traumatic neurologic emergency in childhood. Current algorithms prioritize the use of benzodiazepines as first line treatment followed by Levetiracetam or Valproic Acid, possibly Fosphenytoin and eventually high dose Propofol and intubation. ⋯ A 9-month old girl was brought to the emergency department with a continuous seizure involving the right upper and lower extremity for 45 min prior to arrival. Patient received a dose of rectal Diazepam, intramuscular Midazolam, 2 doses of Lorazepam, Levetiracetam, Fosphenytoin and 2 additional doses of Lorazepam. The seizure remained refractory and generalized. In anticipation of intubation, and because of its action on the NMDA receptor, Ketamine (1 mg/kg IV) was administered. The clonic movements and eye deviations stopped. Patient was intubated for airway protection, sedated with Propofol, then admitted to the PICU. EEG showed no evidence of a seizure pattern. Labs (CBC, CMP, COVID) were unremarkable except for WBC 24.5, blood glucose of 346 and CO2 of 17 with normal anion gap. Urinalysis showed a urinary tract infection. Patient was at her baseline on 1 week post-discharge re-evaluation. Ketamine theoretically may abort seizures through blockade of NMDA receptors which are unregulated in status epilepticus. To date, no randomized controlled trials have been reported. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Ketamine may have a role in treating status epilepticus. It may be considered for induction for rapid sequence intubation and possibly as a third or fourth line agent in refractory cases.

Case Reports
Proximal tibiofibular joint dislocation in young children: Is this the nursemaid's elbow of the lower extremity?
Anterolateral dislocation of the Proximal Tibiofibular Joint (PTFJ) is a rare injury of the knee commonly resulting from violent athletic injuries in adults. Reported here are examples of this injury in a 19 month old and a 4 year old following trivial mechanisms of injury. These cases raise the question of whether this injury may be an unrecognized cause of refusal to bear weight in children in this age group.
