Association Between Allergen Sensitization and Anaphylaxis in Patients Visiting a Pediatric Emergency Department.

ABSTRACT: Background and Objectives: Anaphylaxis, a severe allergic disease, can be triggered by various causes. This study investigated the association between allergic sensitization and anaphylactic symptoms and the severity of anaphylaxis in children. Patients and Methods: A retrospective review of 107 pediatric patients with anaphylaxis was performed between January 1, 2015, and December 31, 2017; 74 patients underwent allergen testing for specific immunoglobulin E. Allergic sensitizations and associations with anaphylactic symptoms and severity were investigated. Results: Overall, 64 (86.5%) patients were sensitized to food or inhalant allergens. In children under 2 years of age, 90.5% were sensitized to food (P = 0.001); in those over 6 years of age, 84.6% were sensitized to inhalant allergens (P = 0.001). Milk sensitization was significantly associated with severe anaphylaxis (P = 0.036). The following symptoms showed significant associations with certain allergen sensitizations: facial edema with food; wheezing with milk; dyspnea with mite, etc. Certain allergen sensitizations presenting as risk factors for anaphylactic symptoms: wheat (adjusted odds ratio [aOR] = 4.644, P = 0.044) and nuts (aOR=3.614, P = 0.041) for wheezing, nuts (aOR=5.201, P = 0.026) for dyspnea, and milk (aOR=4.712, P = 0.048) for vomiting. Conclusion: The allergen sensitization status differed according to the age of the children experiencing anaphylaxis. The severity, symptoms, and signs of anaphylaxis differed depending on the allergen sensitization status.

Project description:BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be associated with myocardial injury. Identification of at-risk patients and mechanisms underlying cardiac involvement in COVID-19 remains unclear. During hospitalization for COVID-19, high troponin level has been found to be an independent variable associated with in-hospital mortality and a greater risk of complications. Electrocardiographic (ECG) abnormalities could be a useful tool to identify patients at risk of poor prognostic. The aim of our study was to assess if specific ECGs patterns could be related with in-hospital mortality in COVID-19 patients presenting to the ED in a European country.MethodsFrom February 1st to May 31st, 2020, we conducted a multicenter study in three hospitals in France. We included adult patients (≥ 18 years old) who visited the ED during the study period, with ECG performed at ED admission and diagnosed with COVID-19. Demographic, comorbidities, drug exposures, signs and symptoms presented, and outcome data were extracted from electronic medical records using a standardized data collection form. The relationship between ECG abnormalities and in-hospital mortality was assessed using univariate and multivariable logistic regression analyses.ResultsAn ECG was performed on 275 patients who presented to the ED. Most of the ECGs were in normal sinus rhythm (87%), and 26 (10%) patients had atrial fibrillation/flutter on ECG at ED admission. Repolarization abnormalities represented the most common findings reported in the population (40%), with negative T waves representing 21% of all abnormalities. We found that abnormal axis (adjusted odds ratio: 3.9 [95% CI, 1.1-11.5], p = 0.02), and left bundle branch block (adjusted odds ratio: 7.1 [95% CI, 1.9-25.1], p = 0.002) were significantly associated with in-hospital mortality.ConclusionsECG performed at ED admission may be useful to predict death in COVID-19 patients. Our data suggest that the presence of abnormal axis and left bundle branch block on ECG indicated a higher risk of in-hospital mortality in COVID-19 patients who presented to the ED. We also confirmed that ST segment elevation was rare in COVID-19 patients.

Project description:ObjectiveLack of trust between supervisors and trainees can have harmful consequences. Trust has been examined between physicians, patients, and staff in multiple settings but has not been examined in a bidirectional manner in the pediatric emergency department (PED). Debra Meyerson in 1996 discussed the theory of swift trust, a type of trust that develops quickly between temporary groups through reliance on categories. Meyerson describes categories as groups unified by social identities such as gender or profession. We explored the applicability of swift trust in the relationship between supervisors and trainees in the PED.MethodsThis multimethods study used qualitative interviews and the validated interpersonal mistrust trust measure (IMTM) to assess baseline trusting style. PED attendings from a single institution and residents from various training levels, specialties, and institutions rotating through the same PED were sampled until thematic saturation was reached. Interviews were analyzed using directed content analysis. IMTM scores were triangulated with interviewee's reported trusting styles.ResultsSeventeen PED attendings and 16 residents participated. Residents and attendings emphasized different factors that influence trust. Common factors across groups included affect, the need for vulnerability, and appropriate communication. Most described reliance on certain categories (level of training, specialty, etc.) when making trusting decisions. Categories such as gender and race were noted to be unimportant when making trusting decisions about others, although some participants believed these attributes played into decisions made by others. Quantitative data from the IMTM supported qualitative conclusions regarding trusting style.ConclusionsThe trusting relationship between supervisors and trainees in the PED dovetails with the swift trust theory. Common factors that influence trust reveal entry points for attendings and residents to improve trust and ultimately prevent negative patient outcomes. Future studies may examine how reliance on categories influences an individual's trust in their colleagues.
