RESUMO
OBJECTIVES: Pediatric myocarditis is a known cause of dilated cardiomyopathy and is associated with significant mortality. Our primary objective was to describe the frequency of presenting symptoms, signs, and investigation results among children diagnosed with acute myocarditis. Our secondary objective was to review these patients' initial diagnoses by the emergency physicians. METHODS: This was a retrospective chart review of all patients younger than 16 years who were diagnosed with acute myocarditis in our hospital over a 10-year period (January 2001 to December 2010). The symptoms and signs were stratified according to age (infants, 1-5 years, 6 years or older). RESULTS: Thirty-nine children met the search criteria, of whom 10 patients (25.6%) were definite cases proven by myocardial biopsy. The average age was 5.4 years (SD, 4.3 years). The most common symptom complex was that of hypoperfusion (61.5%), which consisted of lethargy (53.8%), syncope (23.1%), and seizure (23.1%). Only 4 patients had cardiac symptoms, and all were older than 6 years old. Hepatomegaly was present in 16 patients (41.0%), whereas gallop rhythm or cardiac murmur was heard only in 5 patients (12.8%), Chest radiographs showed abnormalities in only 21 cases (53.8%), whereas all had abnormal electrocardiogram findings. Fifteen cases (38.5%) were diagnosed correctly at initial presentation, whereas the most common misdiagnosis was that of respiratory tract infections (20.5%). CONCLUSIONS: Pediatric myocarditis rarely presents with specific cardiac symptoms in the younger population. Any child with symptoms and signs of hypoperfusion, especially unexplained seizure or syncope, should have an electrocardiogram performed.

INTRODUCTION: Emergency departments (ED) globally are addressing the coronavirus disease 2019 (COVID-19) pandemic with varying degrees of success. We leveraged the 17-country, Emergency Medicine Education & Research by Global Experts (EMERGE) network and non-EMERGE ED contacts to understand ED emergency preparedness and practices globally when combating the COVID-19 pandemic. METHODS: We electronically surveyed EMERGE and non-EMERGE EDs from April 3-June 1, 2020 on ED capacity, pandemic preparedness plans, triage methods, staffing, supplies, and communication practices. The survey was available in English, Mandarin Chinese, and Spanish to optimize participation. We analyzed survey responses using descriptive statistics. RESULTS: 74/129 (57%) EDs from 28 countries in all six World Health Organization global regions responded. Most EDs were in Asia (49%), followed by North America (28%), and Europe (14%). Nearly all EDs (97%) developed and implemented protocols for screening, testing, and treating patients with suspected COVID-19 infections. Sixty percent responded that provider staffing/back-up plans were ineffective. Many sites (47/74, 64%) reported staff missing work due to possible illness with the highest provider proportion of COVID-19 exposures and infections among nurses. CONCLUSION: Despite having disaster plans in place, ED pandemic preparedness and response continue to be a challenge. Global emergency research networks are vital for generating and disseminating large-scale event data, which is particularly important during a pandemic.
