ECG manifestations of occlusion of septal perforator of left anterior descending artery.
The fourth universal definition of MI defines requires presence of j point elevation in two contiguous leads except v2-3 where the elevation should be equal to or >2 mm in men (2.5 mm in <40 years) and 1.5 mm in women.(1) We present two cases of patients who presented with electrocardiographic manifestations of occlusion of septal perforator of left anterior descending artery and discuss the salient feature of ECG in such patients. We also present the limitations of STEMI criteria given the dynamic nature of acute coronary occlusion and stress on early recognition of this MI.

The incidence of infection in open tibial shaft injuries varies with the severity of the injury with rates ranging from roughly 2% for Gustilo-Anderson type I to nearly 43% for type IIIB fractures. As with all fractures, timely antibiotics administration in the emergency department (ED) is an essential component of fracture management and infection prevention. This study identifies factors associated with the expedient administration of antibiotics for open tibial shaft fractures. ⋯ Earlier antibiotic delivery is associated with non-overnight arrival at the ED, arrival via EMS, and a coordinated trauma activation. Our findings indicate that in cases where administering antibiotics is critical to achieving positive outcomes, it is advisable to initiate a coordinated trauma response. Furthermore, hospital personnel should be attentive to the need for rapid administration of antibiotics to patients with open fractures who arrive via walk-in or during late-night hours.

Emergency department (ED) overcrowding presents a global challenge that inhibits prompt care for critically ill patients. Traditional 5-level triage system that heavily rely on the judgment of the triage staff could fail to detect subtle symptoms in critical patients, thus leading to delayed treatment. Unlike previous rivalry-focused approaches, our study aimed to establish a collaborative machine learning (ML) model that renders risk scores for severe illness, which may assist the triage staff to provide a better patient stratification for timely critical cares. ⋯ The traditional 5-level triage system often falls short, leading to under-triage of critical patients. Our models include a score-based differentiation within a triage level to offer advanced risk stratification, thereby promoting patient safety.

Alien hand syndrome: An atypical presentation of acute left parietal stroke in a community emergency department.
A case of Alien hand syndrome as a presentation of an acute left parietal stroke to improve emergency providers recognition of the condition as a manifestation of acute stroke. We report a case of an 81-year-old female who presented with a complaint of inability to control her right arm accompanied with a subjective sense of right upper extremity numbness and weakness. ⋯ This presentation of stroke is important for emergency providers to recognize as it is uncommon, greater awareness by emergency providers may improve stroke outcomes by early detection and activation of routine acute stroke interventions. In this case report a patient presented with alien hand syndrome, with inability to control her right hand along with a subjective complaint of numbness and reduction in strength in the right upper extremity, found to be due to an acute left parietal stroke that was confirmed by MRI imaging.

Does pre-injury anticoagulation make chest tubes any less safe? A nationwide retrospective analysis.
Oral anticoagulation is becoming more common with the aging population, which raises concern for the risk of invasive procedures that can cause bleeding, such as chest tube placement (thoracostomy). With the increase in CT imaging, more pneumothoraces and hemothoraces are being identified. The relative risk of thoracostomy in the presence of anticoagulation is not well-established. The objective of this study was to determine whether pre-injury anticoagulation affects the relative risk of tube thoracostomy following significant chest trauma. ⋯ Therapeutic, Level III.
