Cyclic Vomiting Syndrome in the Emergency Department: A 10-Year Review of Clinical Presentation and Management.

OBJECTIVES: The aims of the study were (1) to determine how frequently patients with cyclic vomiting syndrome (CVS) present to the pediatric emergency department (ED) with CVS-related symptoms, (2) to identify variables in clinical presentation that occur frequently in patients with multiple ED visits, and (3) to compare ED management of CVS with recommended guidelines. METHODS: This study is a retrospective chart review of all ED visits for CVS between April 1, 2008, and April 1, 2018, at a single center. Patients were identified from a master list of patients diagnosed with CVS in a pediatric gastroenterology clinic at the same center between June 1, 2004, and June 19, 2018. RESULTS: Of the 181 CVS clinic patients identified, 65 had visited to the ED (35.9%). Two hundred twenty-eight visits met inclusion criteria. A total of 42.5% of these visits were made by a small number of high-intensity patients (n = 6) who had an average of 16.1 visits each. These patients represented less than 10% of the total patient group. Patients with frequent visits had longer visits (536.52 vs 380.55 minutes), more frequent hospital admissions (57.73% vs 29.01%), and more visits to the ED before a formal diagnosis of CVS was made (5.83 vs 1.22), but few other distinguishing characteristics. Only 27% of eligible visits were managed with an available order set, and management varied from recommended guidelines. CONCLUSIONS: An ambiguous presentation makes the identification and consistent management of CVS in the ED difficult. Physicians should consider CVS for patients who present multiple times with unremitting vomiting to ensure appropriate referral for diagnosis and prophylactic treatment. Future studies are warranted to evaluate anticipatory processing and treatment of the "high-intensity patients" who account for much of the clinical morbidity and resource utilization.

Implementation and facilitation of post-resuscitation debriefing: a comparative crossover study of two post-resuscitation debriefing frameworks.

BACKGROUND: Post-resuscitation debriefing (PRD) is the process of facilitated, reflective discussion, enabling team-based interpersonal feedback and identification of systems-level barriers to patient care. The importance and benefits of PRD are well recognized; however, numerous barriers exist, preventing its practical implementation. Use of a debriefing tool can aid with facilitating debriefing, creating realistic objectives, and providing feedback. OBJECTIVES: To assess utility of two PRD tools, Debriefing In Situ Conversation after Emergent Resuscitation Now (DISCERN) and Post-Code Pause (PCP), through user preference. Secondary aims included evaluating differences in quality, subject matter, and types of feedback between tools and implications on quality improvement and patient safety. METHODS: Prospective, crossover study over a 12-month period from February 2019 to January 2020. Two PDR tools were implemented in 8 week-long blocks in acute care settings at a tertiary care children's hospital. Debriefings were triggered for any intubation, resuscitation, serious/unanticipated patient outcome, or by request for distressing situations. Post-debriefing, team members completed survey evaluations of the PDR tool used. Descriptive statistics were used to analyze survey responses. A thematic analysis was conducted to identify themes that emerged from qualitative responses. RESULTS: A total of 114 debriefings took place, representing 655 total survey responses, 327 (49.9%) using PCP and 328 (50.1%) using DISCERN. 65.2% of participants found that PCP provided emotional support while only 50% of respondents reported emotional support from DISCERN. PCP was found to more strongly support clinical education (61.2% vs 56.7%). There were no significant differences in ease of use, support of the debrief process, number of newly identified improvement opportunities, or comfort in making comments or raising questions during debriefs between tools. Thematic analysis revealed six key themes: communication, quality of care, team function & dynamics, resource allocation, preparation and response, and support. CONCLUSION: Both tools provide teams with an opportunity to reflect on critical events. PCP provided a more organized approach to debriefing, guided the conversation to key areas, and discussed team member wellbeing. When implementing a PRD tool, environmental constraints, desired level of emotional support, and the extent to which open ended data is deemed valuable should be considered.

Surgical versus conservative management of tongue lacerations in the acute care setting: A systematic review of the literature.

Objective: The objective of this study was to determine whether suturing or conservative management of tongue lacerations results in differences in wound healing and functional outcome. The secondary aim was to identify whether antibiotics are required in the treatment of tongue lacerations. Methods: Studies published between December 1954 and August 2020 were extracted from MEDLINE via PubMed, Embase via OVID, CINAHL via EBSCO, Web of Science, and the Cochrane Library and evaluated for inclusion based on predetermined inclusion and exclusion criteria by two independent reviewers in accordance with PRISMA guidelines. Results: The search yielded a total of 16,111 articles, 124 of which were evaluated by full-text review, resulting in 11 articles included in this systematic review representing 142 unique cases of tongue lacerations. At least 26 lacerations (18.3%) included penetration of the muscle layer of the tongue, and 24 (16.9%) were classified as full-thickness lacerations. Thirty-five of the 142 tongue lacerations (24.6%) were sutured. The remaining lacerations underwent some form of conservative management. The majority of studies reported excellent healing of tongue lacerations regardless of the management method, with minimal scarring and excellent return to normal functional status. No cases of infection were reported. Conclusions: Current literature is inconsistent with regards to indications and guidelines for primary repair of tongue lacerations. The majority of tongue lacerations reported in the literature heal with excellent outcomes regardless of management method. Physician judgement along with patient and parental preference based on potential risks of the procedure should be used when deciding whether a tongue laceration requires primary repair. Tongue lacerations in otherwise healthy individuals are at very low risk of infection.

Diagnosis and Acute Management of E-Cigarette or Vaping Product Use-Associated Lung Injury in the Pediatric Population: A Systematic Review.

OBJECTIVE: To assess quantitative data on the presentation, investigative findings, patterns of lung injury, and interventions of pediatric cases of e-cigarette or vaping-associated lung injury (EVALI) in the acute care setting. STUDY DESIGN: A literature search using keywords was performed on April 17, 2020, in accordance with PRISMA guidelines. Three thousand five hundred fifty-eight articles were retrieved from MEDLINE via PubMed, Embase via OVID, CINAHL via EBSCO, Web of Science, and the Cochrane Library. Studies were evaluated for inclusion based on predetermined inclusion and exclusion criteria by 2 independent reviewers. RESULTS: The search yielded a total of 3558 individual results, 145 of which were evaluated by full text review, resulting in 23 articles included in this systematic review. Two of these articles were identified by manual search of article references. A total of 61 cases of EVALI were described, and 10 major patterns of lung injury were identified for which presenting symptoms, diagnostic and laboratory investigations, interventions, and outcomes were synthesized. CONCLUSIONS: Cases of EVALI in the pediatric population have been reported in patients as young as 13 years and often present with respiratory, constitutional, abdominal, and cardiovascular signs and symptoms. Diagnostic findings vary based on the underlying lung injury pattern. However, typical patterns of common findings were identified, including the presence of ground-glass opacities on computed tomography scan and leukocytosis. Mainstays of treatment include the use of corticosteroids, antibiotics, and ventilatory support, including extracorporeal membrane oxygenation. Outcomes range from complete or near complete recovery of lung function to death.

Predicting Adverse Outcomes for Shiga Toxin-Producing Escherichia coli Infections in Emergency Departments.

OBJECTIVE: To assess the performance of a hemolytic uremic syndrome (HUS) severity score among children with Shiga toxin-producing Escherichia coli (STEC) infections and HUS by stratifying them according to their risk of adverse events. The score has not been previously evaluated in a North American acute care setting. STUDY DESIGN: We reviewed medical records of children <18 years old infected with STEC and treated in 1 of 38 participating emergency departments in North America between 2011 and 2015. The HUS severity score (hemoglobin [g/dL] plus 2-times serum creatinine [mg/dL]) was calculated using first available laboratory results. Children with scores >13 were designated as high-risk. We assessed score performance to predict severe adverse events (ie, dialysis, neurologic complication, respiratory failure, and death) using discrimination and net benefit (ie, threshold probability), with subgroup analyses by age and day-of-illness. RESULTS: A total of 167 children had HUS, of whom 92.8% (155/167) had relevant data to calculate the score; 60.6% (94/155) experienced a severe adverse event. Discrimination was acceptable overall (area under the curve 0.71, 95% CI 0.63-0.79) and better among children <5 years old (area under the curve 0.77, 95% CI 0.68-0.87). For children <5 years, greatest net benefit was achieved for a threshold probability >26%. CONCLUSIONS: The HUS severity score was able to discriminate between high- and low-risk children <5 years old with STEC-associated HUS at a statistically acceptable level; however, it did not appear to provide clinical benefit at a meaningful risk threshold.

Management of Toddler's Fractures: A Systematic Review.

OBJECTIVES: The aim of this study was to examine and compare the efficacy of external fixation strategies of toddler's fracture (TF) in acute care settings. Specifically, we aim to identify whether immobilization optimizes clinical outcomes for patients (based on immobilization duration, time to weight-bear/ambulate, and associated complications) compared with nonimmobilization, with a systematic review. STUDY DESIGN: After PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, 2 independent reviewers searched electronic databases OVID Medline, Embase, and CINAHL for studies evaluating the health outcomes of various treatment methods for TF (1937-2019). The studies were chosen based on specific inclusion criteria. The 2 reviewers were looking for primary research articles that assessed health outcomes (such as immobilization duration, time to weight-bear/ambulate, and associated complications) of various treatment strategies for TF Fractures in acute care settings. RESULTS: A total of 2385 articles were initially screened, reviewed, and then narrowed down to 6 studies for an in-depth analysis. Among these 6 studies, 5 were retrospective chart reviews and 1 was a cross-sectional online survey. A total of 565 patients from the retrospective chart reviews and 153 physicians from the cross-sectional online survey were further analyzed. The current evidence shows that there was no significant difference in clinical outcomes (ie, time to weight-bear and immobilization duration) between immobilization and nonimmobilization. CONCLUSIONS: Further large-scale prospective studies examining the clinical outcomes of TF management techniques should be conducted to establish a consistent standardized guideline for TF treatment across acute care settings.

Safety Audits in the Emergency Department: Applying the Threat and Error Model to the Management of Pediatric Diabetic Ketoacidosis.

OBJECTIVES: This study aims to better understand factors that impact management of patients with diabetic ketoacidosis (DKA) in the pediatric emergency department (ED) by novel application of the threat-and-error model, commonly used in the aviation industry. METHODS: This study was a retrospective chart review of all patients diagnosed with DKA and managed in our pediatric ED during a 1-year period. A "flight plan" was created for each patient's ED visit, from triage to final disposition. Each flight was analyzed with the goal of identifying threats and errors that may impact patients' clinical status or management. Particular focus was placed on physicians' adherence to hospital and provincial DKA protocols. Unintended patient states or outcomes were also noted. RESULTS: A total of 46 patient flights were outlined and analyzed. A total of 146 threats were identified, affecting 43 (93%) patient flights. No flight was error-free. Errors in communication and lack of adherence to protocol were the most common types of errors. Unintended patient states occurred in 30 cases (65%), some of which were preceded by at least 1 error. There were no cases of cerebral edema or death. CONCLUSIONS: It is important to identify and appropriately mitigate threats and errors that commonly occur during initial management of DKA in the ED to prevent unintended states and patient morbidity. This study demonstrates the threat-and-error model as a potentially useful tool for focusing quality improvement initiatives in the pediatric ED setting.

Effect of the COVID-19 Pandemic on Patient Volumes, Acuity, and Outcomes in Pediatric Emergency Departments: A Nationwide Study.

OBJECTIVES: The aim of this study was to quantify the effect of the COVID-19 pandemic on pediatric emergency department (ED) utilization and outcomes. METHODS: This study is an interrupted-time-series observational study of children presenting to 11 Canadian tertiary-care pediatric EDs. Data were grouped into weeks in 3 study periods: prepandemic (January 1, 2018-January 27, 2020), peripandemic (January 28, 2020-March 10, 2020), and early pandemic (March 11, 2020-April 30, 2020). These periods were compared with the same time intervals in the 2 preceding calendar years. Primary outcomes were number of ED visits per week. The secondary outcomes were triage acuity, hospitalization, intensive care unit (ICU) admission, mortality, length of hospital stay, ED revisits, and visits for trauma and mental health concerns. RESULTS: There were 577,807 ED visits (median age, 4.5 years; 52.9% male). Relative to the prepandemic period, there was a reduction [-58%; 95% confidence interval (CI), -63% to -51%] in the number of ED visits during the early-pandemic period, with concomitant higher acuity. There was a concurrent increase in the proportion of ward [odds ratio (OR), 1.39; 95% CI, 1.32-1.45] and intensive care unit (OR, 1.20; 95% CI, 1.01-1.42) admissions, and trauma-related ED visits among children less than 10 years (OR, 1.51; 95% CI, 1.45-1.56). Mental health-related visits in children declined in the early-pandemic period (in <10 years, -60%; 95% CI, -67% to -51%; in children ≥10 years: -56%; 95% CI, -63% to -47%) relative to the pre-COVID-19 period. There were no differences in mortality or length of stay; however, ED revisits within 72 hours were reduced during the early-pandemic period (percent change: -55%; 95% CI, -61% to -49%; P < 0.001). CONCLUSIONS: After the declaration of the COVID-19 pandemic, dramatic reductions in pediatric ED visits occurred across Canada. Children seeking ED care were sicker, and there was an increase in trauma-related visits among children more than 10 years of age, whereas mental health visits declined during the early-pandemic period. When faced with a future pandemic, public health officials must consider the impact of the illness and the measures implemented on children's health and acute care needs.

Predicting Hemolytic Uremic Syndrome and Renal Replacement Therapy in Shiga Toxin-producing Escherichia coli-infected Children.

BACKGROUND: Shiga toxin-producing Escherichia coli (STEC) infections are leading causes of pediatric acute renal failure. Identifying hemolytic uremic syndrome (HUS) risk factors is needed to guide care. METHODS: We conducted a multicenter, historical cohort study to identify features associated with development of HUS (primary outcome) and need for renal replacement therapy (RRT) (secondary outcome) in STEC-infected children without HUS at initial presentation. Children aged <18 years who submitted STEC-positive specimens between January 2011 and December 2015 at a participating study institution were eligible. RESULTS: Of 927 STEC-infected children, 41 (4.4%) had HUS at presentation; of the remaining 886, 126 (14.2%) developed HUS. Predictors (all shown as odds ratio [OR] with 95% confidence interval [CI]) of HUS included younger age (0.77 [.69-.85] per year), leukocyte count ≥13.0 × 103/µL (2.54 [1.42-4.54]), higher hematocrit (1.83 [1.21-2.77] per 5% increase) and serum creatinine (10.82 [1.49-78.69] per 1 mg/dL increase), platelet count <250 × 103/µL (1.92 [1.02-3.60]), lower serum sodium (1.12 [1.02-1.23 per 1 mmol/L decrease), and intravenous fluid administration initiated ≥4 days following diarrhea onset (2.50 [1.14-5.46]). A longer interval from diarrhea onset to index visit was associated with reduced HUS risk (OR, 0.70 [95% CI, .54-.90]). RRT predictors (all shown as OR [95% CI]) included female sex (2.27 [1.14-4.50]), younger age (0.83 [.74-.92] per year), lower serum sodium (1.15 [1.04-1.27] per mmol/L decrease), higher leukocyte count ≥13.0 × 103/µL (2.35 [1.17-4.72]) and creatinine (7.75 [1.20-50.16] per 1 mg/dL increase) concentrations, and initial intravenous fluid administration ≥4 days following diarrhea onset (2.71 [1.18-6.21]). CONCLUSIONS: The complex nature of STEC infection renders predicting its course a challenge. Risk factors we identified highlight the importance of avoiding dehydration and performing close clinical and laboratory monitoring.

Toxic Shock Syndrome: Still a Timely Diagnosis.

BACKGROUND: Toxic shock syndrome (TSS) is an acute, severe, toxin-mediated disease, characterized by fever, hypotension, and multiorgan system involvement. Toxic shock syndrome has made headlines because of its high associated morbidity and mortality rate in previously healthy young females. Incidence peaked in the early 1980s owing to increased usage of ultra-absorbent tampons. After improved patient education and tampon labeling, the incidence of menstrual TSS has declined. CASE: A previously healthy 14-year-old girl presented to an urgent care center with a 2-day history of fever, erythematous maculopapular rash, vomiting, diarrhea, and malaise. She was found to be tachycardic and hypotensive. Investigations revealed thrombocytopenia, an elevated white count and lactate, and acute kidney injury, consistent with septic shock. Recent tampon usage with menstruation was reported, and a pelvic examination revealed purulent vaginal discharge. The patient was transferred to a pediatric intensive care unit for antibiotic and vasopressor therapy. Vaginal swabs later tested positive for Staphylococcus aureus and TSS toxin-1. CONCLUSIONS: Although the incidence of TSS has decreased in recent years, it is crucial that clinicians rapidly recognize and treat this life-threatening condition. Emergency physicians should always have a high index of suspicion for TSS in young females presenting without another obvious cause of shock. A pelvic examination should always be completed in these cases.

Acute Management of Pediatric Cyclic Vomiting Syndrome: A Systematic Review.

OBJECTIVES: To synthesize quantitative and qualitative data on pharmacologic interventions of pediatric cyclic vomiting syndrome and their effectiveness in disease management in the acute care setting. STUDY DESIGN: Using keywords, 799 studies published up from December 1954 to February 2018 were extracted from MEDLINE via Pubmed, Embase via OVID, CINAHL via EBSCO, and Cochrane Controlled Trials Registry. Studies were evaluated for inclusion and exclusion by 2 independent reviewers using predetermined inclusion and exclusion criteria. RESULTS: The search yielded 84 studies for full review, of which 54 were included in the systematic review. Studies were subsequently separated into 1 group of 6 case series studies containing quantitative data on sumatriptan, ondansetron, phenothiazines, prokinetic agents, carbohydrate, isometheptene, and aprepitant; 1 one group consisting only of qualitative studies containing expert recommendations. CONCLUSIONS: Ondansetron has the most quantitative and qualitative evidence to support its inclusion in pediatric emergency department protocols as a rescue therapy. Sumatriptan and aprepitant are potential candidates for inclusion as abortive therapies. Qualitative data from retrospective studies and case reports are not applicable to a larger patient population. This report informs a need for controlled, prospective cohort studies and randomized, controlled trials to optimize current management protocols and to develop new medical interventions.

The impact of pediatric emergency department crowding on patient and health care system outcomes: a multicentre cohort study.

BACKGROUND: Emergency department overcrowding has been associated with increased odds of hospital admission and mortality after discharge from the emergency department in predominantly adult cohorts. The objective of this study was to evaluate the association between crowding and the odds of several adverse outcomes among children seen at a pediatric emergency department. METHODS: We conducted a retrospective cohort study involving all children visiting 8 Canadian pediatric emergency departments across 4 provinces between 2010 and 2014. We analyzed the association between mean departmental length of stay for each index visit and hospital admission within 7 days or death within 14 days of emergency department discharge, as well as hospital admission at index visit and return visits within 7 days, using mixed-effects logistic regression modelling. RESULTS: A total of 1 931 465 index visits occurred across study sites over the 5-year period, with little variation in index visit hospital admission or median length of stay. Hospital admission within 7 days of discharge and 14-day mortality were low across provinces (0.8%-1.5% and < 10 per 100 000 visits, respectively), and their association with mean departmental length of stay varied by triage categories and across sites but was not significant. There were increased odds of hospital admission at the index visit with increasing departmental crowding among visits triaged to Canadian Triage and Acuity Scale (CTAS) score 1-2 (odds ratios [ORs] ranged from 1.01 to 1.08) and return visits among patients with a CTAS score of 4-5 discharged at the index visit at some sites (ORs ranged from 1.00 to 1.06). INTERPRETATION: Emergency department crowding was not significantly associated with hospital admission within 7 days of the emergency department visit or mortality in children. However, it was associated with increased hospital admission at the index visit for the sickest children, and with return visits to the emergency department for those less sick.

A Rare Pediatric Case of Posttraumatic Pseudoaneurysm: Case Report and Literature Review.

Posttraumatic pseudoaneurysms are extremely rare in pediatric populations. In many cases, pseudoaneurysms may be confused with abscesses, epidermoid cysts, arteriovenous fistula, foreign objects, and ganglion cysts, as well as tumors. They are associated with distinguishing findings of "pulsatile mass, a palpable thrill, and an audible to-and-fro murmur" (1), which can be confirmed by various imaging techniques. In this report, we describe the case of a 4-year-old boy who presented to the pediatric emergency department 3 weeks after falling and subsequently getting cut by glass. Upon clinical examination, the patient presented with pulsatile, swollen mass in the left wrist. A Doppler ultrasound of the left wrist demonstrated that the area of clinical concern in the left wrist showed a pseudoaneurysm, and prominent arterial blood flow was seen within the pseudoaneurysm. Because pseudoaneurysms, particularly posttraumatic pseudoaneurysms, are extremely rare in the pediatric population, it may be easy to miss these cases during clinical examination. Misdiagnosis of the pseudoaneurysm can cause delayed treatment, a longer recovery period, and complications such as infection, rupture, and hemorrhage. It is important for physicians to consider this entity when evaluating patients with symptoms of asymptomatic bulges to painful pulsatile masses after trauma.

Ovarian Torsion in a Pediatric Patient: The Importance of Repeat Imaging.

A previously healthy 10-year-old girl presented to the emergency department with a 1-day history of abdominal pain. She was afebrile with an elevated white blood cell count and a negative pelvic ultrasound. The pain resolved while in hospital, and the patient was discharged home. The patient returned 10 days later, and the pain now migrated from the left flank to the subumbilical region. The patient now had an elevated white blood cell count and C-reactive protein. On pelvic ultrasound, the patient had a large midline mass and a normal right ovary. The patient was taken to the operating room where she was found to have a torted and necrotic left ovary and fallopian tube, which were removed. There are few instances where pediatric ovarian torsion presents as intermittent episodes of abdominal pain. Emergency physicians should always have a high index of suspicion for ovarian torsion in any case of abdominal/pelvic pain in young girls with previous negative imaging.

Ethics consultation in paediatric and adult emergency departments: an assessment of clinical, ethical, learning and resource needs.

OBJECTIVE: We sought to understand ethics and education needs of emergency nurses and physicians in paediatric and adult emergency departments (EDs) in order to build ethics capacity and provide a foundation for the development of an ethics education programme. METHODS: This was a prospective cross-sectional survey of all staff nurses and physicians in three tertiary care EDs. The survey tool, called Clinical Ethics Needs Assessment Survey, was pilot tested on a similar target audience for question content and clarity. RESULTS: Of the 123 participants surveyed, 72% and 84% of nurses and physicians fully/somewhat agreed with an overall positive ethical climate, respectively. 69% of participants reported encountering daily or weekly ethical challenges. Participants expressed the greatest need for additional support to address moral distress (16%), conflict management with patients or families (16%) and resource issues (15%). Of the 23 reported occurrences of moral distress, 61% were associated with paediatric mental health cases. When asked how the ethics consultation service could be used in the ED, providing education to teams (42%) was the most desired method. CONCLUSIONS: Nurses report a greater need for ethics education and resources compared with their physician colleagues. Ethical challenges in paediatric EDs are more prevalent than adult EDs and nurses voice specific moral distress that are different than adult EDs. These results highlight the need for a suitable educational strategy, which can be developed in collaboration with the leadership of each ED and team of hospital ethicists.

Treating and reducing anxiety and pain in the paediatric emergency department-TIME FOR ACTION-the TRAPPED quality improvement collaborative.

BACKGROUND/OBJECTIVES: In 2013, the TRAPPED-1 survey reported inconsistent availability of pain and distress management strategies across all 15 Canadian paediatric emergency department (PEDs). The objective of the TRAPPED-2 study was to utilize a procedural pain quality improvement collaborative (QIC) and evaluate the number of newly introduced pain and distress-reducing strategies in Canadian PEDs over a 2-year period. METHODS: A QIC was created to increase implementation of new strategies, through collaborative information sharing among PEDs. In 2015, 11 of the 15 Canadian PEDs participated in the TRAPPED QIC. At the end of the year, the TRAPPED-2 survey was electronically sent to a representative member at each of the 15 PEDs. The successful introduction of the chosen strategies by the QIC was assessed as well as the addition of new strategies per site. The number of new strategies introduced in the participating and nonparticipating QIC sites were described. RESULTS: All 15 PEDs (100%) completed the TRAPPED-2 survey. Overall, 10/11 of QIC-participating sites implemented the strategy they had initially identified. All 15 Canadian PEDs implemented some new strategies during the study period; participants in the QIC reported a mean of 5.2 (1-11) new strategies compared to 2.5 (1-4) in the nonactively participating sites. CONCLUSION: While all PEDs introduced new strategies during the study, QIC-participating sites successfully introduced the majority of their previously identified new strategies in a short time period. Sharing deadlines and information between centres may have contributed to this success.

An Interesting Case of Viral Pericarditis.

A previously healthy 14-year-old girl presented to the emergency department with a 3-day history of upper respiratory symptoms and 2 syncopal episodes. She was initially febrile, tachycardic, and tachypneic; the initial electrocardiogram showed diffuse T-wave inversions and right atrial enlargement. There was no pericardial effusion on bedside and formal echocardiography; the latter, however, revealed a hyperechogenic pericardium. A viral swab was positive for influenza B. Treatment with intravenous rehydration and ibuprofen was started with good response. The patient went home 24 hours later with the diagnosis of mild pericarditis and syncope likely secondary to dehydration impaired diastolic filling.The incidence of acute pericarditis in previously healthy children is unknown. There are no known case reports of influenza B-associated pericarditis in the pediatric population. There is little high quality evidence to guide the diagnosis and management of pericarditis in children. However, limited data suggest that the typically described presentation of chest pain, pericardial rub, pericardial effusion, and electrocardiogram changes occurs in children. The pediatric population seems to respond well to nonsteroidal anti-inflammatory drugs.
