Foreign body aspiration score (FOBAS)-a prospectively validated algorithm for the management and prediction of foreign body aspiration in children.

Foreign body aspiration (FBA) is a common cause of pediatric morbidity, but a standardized protocol to guide decision-making about bronchoscopy is lacking. We aimed to validate a new Foreign body aspiration score (FOBAS) for the pediatric emergency department (ED). Patients aged 0-18 years referred to the ED for suspected FBA were prospectively enrolled. FOBAS was calculated according to clinical features of a choking episode, sudden cough, exposure to nuts, absence of fever and rhinitis, stridor, and unilateral auscultatory and radiological findings. FBA risk was evaluated based on the total score (low, 1-3; moderate, 4-6; high, 7-10). Low-risk children were discharged from the ED and followed clinically. Moderate-risk children were hospitalized and evaluated by a pediatric pulmonologist, and high-risk children were referred directly for therapeutic bronchoscopy. Among the 100 enrolled children (59% males; median age 20 [interquartile range 11-39] months), a foreign body was diagnosed in 1/49 (2%), 14/41 (34.1%), and 9/10 (90%) with low, moderate, and high FOBAS, respectively (P < .001). Logistic regression indicated a higher risk for FBA with higher scores. The odds ratio for each additional point was 2.75 (95% confidence interval 1.78-4.24), and FOBAS showed a high predictive value for FBA (area under the curve 0.89). FOBAS implementation significantly reduced the rate of negative bronchoscopies, from 67.4% annually during 2016-2019 to 50% in 2020 (P = .042). CONCLUSION: FOBAS reliably predicts FBA in cases of suspected FBA and improves management and in-hospital decision-making. WHAT IS KNOWN: • Foreign body aspiration is a major cause of pediatric morbidity and mortality. • Currently, there is no unified protocol for children referred to the emergency department for suspected FBA, therefore, a well-defined algorithm is needed to improve the decision-making process. WHAT IS NEW: • The pediatric Foreign body aspiration score (FOBAS) is a new, prospectively validated clinical score that shows high sensitivity and specificity for the presence of FBA in children. • FOBAS reduces unnecessary admissions and invasive procedures and leads to better clinical outcomes.

Evaluation of Foreign body aspiration score (FOBAS) in children- A retrospective cohort study.

Foreign Body Aspiration (FBA) is a common medical emergency among young children, but the evaluation and management of a suspected FBA case can vary across physicians and centers. We aimed to identify which clinical, laboratory, and radiological findings can predict FBA in children and to evaluate a clinical score to improve FBA prediction. This is a retrospective cohort study of patients aged 0-18 years admitted to Soroka University Medical Center between 2010 and 2020 with suspected FBA. All patients underwent flexible bronchoscopy and were divided into positive and negative FBA groups. A newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, was evaluated for its predictability. The study included 412 children (median age 21 months, 56.8% females), of whom 154 (37.4%) had FBA and 258 (62.6%) did not. Multivariate regression analysis showed exposure to nuts/seeds, unilateral wheezing or decreased breath sounds, stridor, and suggestive findings on chest X-ray were significant risk factors for FBA (OR [95%CI] -1.994[1.290-3.082], 1.487[1.206-1.832], 1.883 [1.011-3.509] and 2.386[1.917-2.970], respectively). However, a choking episode, acute cough, and absence of fever and rhinorrhea did not predict FBA. FOBAS showed an increased risk of FBA for each additional point of the score, with an odds ratio of 1.572 (95% CI-1.389-1.799).  Conclusion: FOBAS is a good predictor for the presence of FBA in children. Once prospectively validated, FOBAS could aid in decision-making at the emergency department, enabling more standardized care, reducing unnecessary procedures, and leading to better clinical outcomes. What is Known: • The evaluation and management of a child with suspected foreign body aspiration (FBA) vary across physicians and centers, without a consensus regarding the indications and criteria for performing bronchoscopy. • Flexible bronchoscopy is the standard procedure for the diagnosis and sometimes treatment of FBA in children, but it may hold potential complications. What is New: • We propose a newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, for the prediction of FBA in children at the emergency department. • The FOBAS is a good predictor of FBA in children. The score enables more standardized care and may reduce unnecessary procedures.

Comparison of chest X-ray interpretation by pediatric pulmonologists, pediatric radiologists, and pediatric residents in children with suspected foreign body aspiration-a retrospective cohort study.

Chest X-ray (CXR) is an important tool in the assessment of children with suspected foreign body aspiration (FBA), although it can falsely be interpreted as normal in one-third of the cases. The aim of this study is to evaluate the positive predictive value of CXR in children hospitalized with suspected FBA, when interpreted by three disciplines: pediatric pulmonology, pediatric radiology, and pediatric residents. This is a retrospective study that included children aged 0-18 years, admitted with suspected FBA, between 2009 and 2020 in one tertiary center. All patients underwent CXR and a flexible/rigid bronchoscopy for the definitive diagnosis of FBA, up to 1 week apart. Two physicians from each discipline interpreted the CXR, independently. Intra-raters' and inter-raters' agreements were assessed. Sensitivity, specificity, and area under the curve (AUC) were calculated for each discipline. Four hundred seventy-three children were included in the study, 175 (37%) with FBA and 298 (63%) without FBA on flexible/rigid bronchoscopy. The most common radiological findings, as interpreted by a pediatric pulmonologist, were unilateral hyperinflation (47%), radiopaque FB (37.6%), lobar atelectasis (10.3%), unilateral hyperinflation with atelectasis (3.4%), and lobar consolidation (1.7%). Intra-raters' agreement ranged from 0.744 (p < 0.001) among pediatric pulmonologists to 0.326 (p < 0.001) among pediatric radiologists. AUC for predicting FBA based on a CXR was 0.81, 0.77, and 0.7 when interpreted by pediatric pulmonologists, pediatric residents, and radiologists, respectively (p < 0.001). CONCLUSIONS: CXR has a high positive predictive value and independently predicts FBA in children; however, normal CXR should not rule out FBA. Predictability is variable among different disciplines. WHAT IS KNOWN: • Chest X-ray is an important tool in the assessment of children with suspected foreign body aspiration (FBA). • Chest X-ray can be interpreted as normal in one-third of the cases. WHAT IS NEW: • Chest X-ray independently predicts FBA in children, with a high positive predictive value. • The ability of chest x-ray to predict FBA in children differs between pediatric residents, pediatric radiologists, and pediatric pulmonologists.

Neurologic Manifestations of Influenza in Children.

OBJECTIVE: We assessed the neurologic manifestation of influenza among hospitalized children with influenza (neuro-flu), comparing their demographic and clinical characteristics to hospitalized children without neurologic manifestation (classic-flu). METHODS: A retrospective, cohort study. All children with laboratory confirmed influenza (PCR), admitted to the Soroka University Medical Center (SUMC) between 2016 and 2019 were included. RESULTS: Overall, 951 patients were identified: 201 with neuro-flu, and 750 with classic-flu. Seizures (n = 125) were the most common neurological manifestation of neuro-flu (seizure-flu): 73 simple febrile seizures, 45 atypical febrile seizures, and 7 afebrile seizures. Neurological comorbidities rates were significantly higher in neuro-flu versus classic-flu (13.0% vs. 6.0%), while respiratory and cardiac comorbidities were less common in neuro-flu (4.5% and 0.5% vs. 8.0% and 4.5%, respectively). Neuro-flu (compared with classic-flu) was associated with leukocytosis (21.0% vs. 13.0%, P < 0.001) and lower C-reactive protein (CRP) levels (2.4 ± 4.1 vs. 3.3 ± 5.4, P = 0.03). Notably, patients with classic flu had a more prominent respiratory disease, as they had more chest radiographs (CXR) performed (60.5% vs. 45.0%, P < 0.001), higher rates of pneumonia (27.0% vs. 12.0%, P < 0.001), and antibiotic (antibacterial) treatment (60.0% vs. 42.0%, P < 0.001). CONCLUSIONS: Influenza can appear as a neurologic disease, manifested mainly with febrile seizures. Children with neuro-flu have more neurologic comorbidities, suggesting that neuro-flu is mainly driven by host-factors, rather than by pathogen-factors. The relatively lower rates of pneumonia in neuro-flu suggests that these patients are admitted in the early stage of the influenza infection, which triggers the neurologic response.
