ABSTRACT
OBJECTIVE: Dehydration is a common concern in children presenting to pediatric emergency departments and other acute care settings. Ultrasound (US) of the inferior vena cava (IVC) may be a fast, noninvasive tool to gauge volume status, but its utility is unclear. Our objectives were to determine the interobserver agreement of IVC collapse and collapse duration, then correlate IVC collapse with the outcome of intravenous (IV) versus oral (PO) rehydration. METHODS: We conducted a prospective study by enrolling patients 0 to 21 years old with emesis requiring ondansetron or diarrhea requiring IV hydration. Clinical operators interpreted US examinations in real time to determine whether the IVC was collapsed. Two blinded reviewers interpreted the US videos to determine IVC collapse and collapse duration. Cohen's kappa(κ) was calculated for reviewer-reviewer and reviewer-operator agreement. Primary outcomes were PO versus IV rehydration, and admitted versus discharged. RESULTS: One hundred twelve patients were enrolled, and 102 had complete data for analysis. The mean age was 7.2 years with 51% female. Twenty-nine patients received IV hydration. The reviewer-operator agreement for IVC collapse was κ = 0.57 (95% confidence interval [CI], 0.38-0.75) and interreviewer agreement was κ = 0.93 (95% CI, 0.83-1.0). The interreviewer agreement for collapse duration was κ = 0.66 (95% CI, 0.51-0.82). All patients with noncollapsed IVCs tolerated PO hydration. The likelihood of receiving IV hydration was correlated with the duration of IVC collapse (P = 0.034). CONCLUSIONS: Based on a novel dynamic measure of IVC collapse duration, children with increasing duration of IVC collapse correlated positively with the need for IV rehydration. Noncollapsing IVCs on US were associated with successful PO rehydration without need for IV fluids or emergency department revisits.

Although group A Streptococcus (GAS) pharyngitis is the most common cause of bacterial pharyngitis in children and adolescents, many viral and bacterial infections mimic the symptoms of GAS pharyngitis. Emergency clinicians must recognize the symptomatology of GAS pharyngitis and use appropriate means of diagnosis and treatment to promote good antibiotic stewardship. This issue reviews the signs and symptoms of GAS pharyngitis, as well as associated complications, and provides recommendations for appropriate treatment that focuses on reducing the severity and duration of symptoms, reducing the incidence of nonsuppurative complications, and reducing transmission.

More than 1.7 million traumatic brain injuries occur in adults and children each year in the United States, with approximately 30% occurring in children aged < 14 years. Traumatic brain injury is a significant cause of morbidity and mortality in pediatric trauma patients. Early identification and management of severe traumatic brain injury is crucial in decreasing the risk of secondary brain injury and optimizing outcome. The main focus for early management of severe traumatic brain injury is to mitigate and prevent secondary injury, specifically by avoiding hypotension and hypoxia, which have been associated with poorer outcomes. This issue discusses methods to maintain adequate oxygenation, maximize management of intracranial hypertension, and optimize blood pressure in the emergency department to improve neurologic outcomes following pediatric severe traumatic brain injury.

Brugada syndrome (BrS) is rare genetic disorder, which manifests as syncope or sudden death caused by polymorphic ventricular tachycardia. Diagnosis is based on symptoms and characteristic electrocardiography findings. Identification of mutations in SCN5A support the diagnosis, but the yield is low. According to experts, BrS patients with a history of cardiac arrest should have insertion of an automatic implantable cardiac defibrillator and asymptomatic patients can be managed conservatively. Treatment challenges occur in patients with "intermediate" clinical characteristics and in populations where there is paucity of data such as with neonates and children. We discuss the case of a woman with BrS who is faced with decision challenges in the postpartum period. Should her newborn have testing? When? Will deferment of testing impose an unreasonable uncertainty due to delay of diagnosis? Or conversely, will premature workup impose an unnecessary intervention?
