Catatonia is a poorly understood and underrecognized psychomotor condition characterized by three or more catatonic symptoms, commonly including abnormalities in speech, affect, and movement. Catatonia is generally associated with psychiatric disorders such as bipolar disorder and schizophrenia, but may be seen in general medical conditions and rarely after physical trauma. Here, we present the first pediatric case of catatonia following traumatic brain injury as well as the first case of catatonia in any patient following minor traumatic brain injury.

Observational Study
The LIMIT-NI clinical decision instrument reduces neuroimaging compared to unstructured clinician judgement in recurrent seizure patients.
The LIMIT clinical decision instrument (CDI) was published in 2021 to safely reduce neuroimaging in patients with recurrent seizures. The LIMIT CDI had a sensitivity of 90%, negative predictive value of >99.9%, and reduced neuroimaging by 13.3%. However, the design of the original LIMIT CDI made it cumbersome to use. The goal of this study was to validate the streamlined LIMIT-NeuroImaging (LIMIT-NI) CDI and compare its performance to the original LIMIT CDI. ⋯ The LIMIT-NI CDI demonstrated greater ease of application and improved test characteristics compared to the original LIMIT CDI. Compared to unstructured clinician judgement, the LIMIT-NI CDI reduced neuroimaging by 15.8% (relative reduction 40.2%) in recurrent seizure patients. The LIMIT-NI CDI can be used by physicians along with clinical judgement to reduce neuroimaging in the recurrent seizure patient.

Case Reports
Point of care ultrasound needle guidance to assist diagnosis of acute gluteal compartment syndrome.
Gluteal compartments can be difficult to assess for acute compartment syndrome (ACS) compared to other fascial compartments due to their anatomy and rarity of presentation. Point-of-care ultrasound (POCUS) needle guidance may assist in obtaining accurate compartment pressure measurements within the gluteal compartments. We present a case in which a 69-year-old woman presented following a fall resulting in a superior prosthetic hip dislocation. ⋯ The patient was subsequently taken for emergent fasciotomy and hematoma evacuation. There has been limited investigation into compartment pressure measurement under US guidance versus a palpation/landmark-guided technique. This case shows the feasibility of US needle guidance when assessing compartment pressures for this uncommon diagnosis.

Case Reports
A rare combination of methemoglobinemia and carboxyhemoglobinemia in pesticide poisoning.
Dyshemoglobinemias are disorders in which the haemoglobin is functionally altered and prevented from carrying oxygen. They include carboxyhemoglobin, methemoglobin, and sulfhemoglobin. This increase in abnormal haemoglobin has reduced oxygen binding capacity, which leads to decrease in total oxygen content in the blood causing anaemic-hypoxia. ⋯ The patient's signs and symptoms gradually reduced in a few days and got discharged after 2 weeks without any neurological and cardiorespiratory sequelae. An early suspicion and personalized emergency management was the key to success. As in all fields of Medicine, Emergency Medicine is also witnessing a change towards precision and personalized Medicine practice.

With respect to reversal of life threatening bleeds associated with the use of oral factor Xa inhibitors, current guidelines provide few recommendations for a preferred reversal agent. When the initial reversal agent fails to achieve the desired hemostatic response, there is little to no recommendations for the use of additional reversal agents. ⋯ An 86-year-old female on apixaban (ELIQUIS) for atrial fibrillation, presented from an outside hospital due to a spontaneous intracranial hemorrhage (sICH). Computed tomography (CT) scan revealed multifocal left sided sICH. Due to use of apixaban in the setting to sICH, patient received andexanet alfa (AA) for reversal. Patient was then transferred and upon arrival to receiving emergency department (ED), repeat CT scans showed an expanding sICH, progression of midline shift, and low-molecular weight heparin levels that were ≥ 2 international units (IU) per milliliter (mL), indicating therapeutic apixaban activity. The patient was subsequently given four-factor prothrombin complex concentrate (4F-PCC). WHY AN EMERGENCY MEDICINE PHYSICIAN SHOULD BE AWARE OF THIS INCLUDE THE FOLLOWING KEY POINTS.
