Case Reports
Brugada pattern exposed with administration of amiodarone during emergent treatment of ventricular tachycardia.
Brugada pattern is a well-known pathological finding on electrocardiogram (ECG) which increases the likelihood of cardiac arrest due to ventricular arrhythmia. These cases generally present in younger patients without evidence of an electrolyte abnormality, structural heart disease, or cardiac ischemia. In many instances, this pattern is either hidden on initial presentation or presents as an incidental finding on an EKG. Often times the Brugada syndrome leads to sudden cardiac death or more rarely can be unmasked with a class 1A or 1C anti-arrhythmic agent. Here, we present a distinctive case in which the pattern was exposed by amiodarone during the emergent treatment of Ventricular Tachycardia (VT). ⋯ This case emphasizes the awareness needed to seek out this pattern on subsequent ECG's. With the high lethality of Brugada, the emergency physician must recognize that multiple drugs can evoke this pattern after initial presentation.

Observational Study
Hypoglycemia as a complication of intravenous insulin to treat hyperkalemia in the emergency department.
Complications associated with the emergency department (ED) management of hyperkalemia are not well characterized. The goals of this study were to describe the frequency of hypoglycemia following the use of insulin to shift potassium intracellularly and to examine the association of key variables with this complication. ⋯ Hypoglycemia is a frequent complication of treatment with IV insulin in the ED. Interventions such as standardized protocols to assist with the ED management of hyperkalemia should be developed; their efficacy and safety should be compared.

Diagnosis of acute ischemic stroke is critical for acute intervention. Its diagnosis may be obscured in trauma patients due to confounding injuries. We report its incidence in trauma patients following their presentation at our institution. ⋯ Acute ischemic stroke in trauma patients was a frequent diagnosis albeit with delay. Routine craniocervical vascular imaging at the time of presentation could potentially facilitate early diagnosis. A prospective study with routine craniocervical vascular imaging in trauma patients will be needed to further explore this hypothesis.

We aimed to identify how patient (age, sex, condition) and paramedic factors (sex, role) affected prehospital analgesic administration and pain alleviation. ⋯ There was no association between patient sex or ambulance staff sex or grade and analgesic administration or pain reduction.

Observational Study
Procalcitonin as a diagnostic marker for sepsis/septic shock in the emergency department; a study based on Sepsis-3 definition.
The recent definition of sepsis was modified based on a scoring system focused on organ failure (Sepsis-3). It would be a time-consuming process to detect the sepsis patient using Sepsis-3. Procalcitonin (PCT) is a well-known biomarker for diagnosing sepsis/septic shock and monitoring the efficacy of treatment. We conducted a study to verify the predictability of PCT for diagnosing sepsis based on Sepsis-3 definition. ⋯ PCT is a reliable biomarker to predict sepsis or septic shock according to the Sepsis-3 definitions.
