The aim of the present study was to assess the efficacy of intravenous (IV) magnesium sulfate (MgSO4) for children with bronchiolitis. A retrospective cohort study was performed at a pediatric emergency department. Aged between 1 and 24 months, children with moderate/severe bronchiolitis according to the Modified Respiratory Distress Assessment Instrument (mRDAI) score were included. Patients who received 40 mg/kg/dose of IV MgSO4 (group 1, n: 74) or not (group 2, n: 33) were compared. Respiratory rate and mRDAI score significantly decreased at the second hour of MgSO4 treatment and the decrease was observed for 4th, 8th, and 12th hours, compared with group 2. Patients in group 2 had a higher rate of requirement and an earlier start high-flow nasal cannula oxygen therapy and a longer hospital stay than group 1. Intravenous MgSO4 provided significant improvement on clinical severity, need for respiratory support, length of hospital stay, and outcomes. [ABSTRACT FROM AUTHOR]

Background: Lower respiratory tract infections (LTRIs) are the most common cause of pediatric emergency department visits and are associated with significant morbidity and mortality. The aim of this study was to evaluate the soluble urokinase plasminogen activator receptor (suPAR) levels in pediatric patients with LRTIs and to investigate the correlation of suPAR with disease severity. Methods: This is a prospective case–control study of children with LTRIs. Demographic data, diagnoses, vital signs, disease severity scores, length of hospital stay, laboratory findings, and viral polymerase chain reaction results for nasopharyngeal aspirates were recorded. Blood samples for suPAR were collected and assessed by enzyme-linked immunosorbent assay. Results: There were 94 patients with LTRIs and 32 children in the control group. Patients were further subdivided into 2 groups based on diagnosis of acute bronchiolitis (n: 31, 33%) or pneumonia (n: 63, 67%). The median levels of suPAR were significantly higher in patients with LTRIs than in healthy controls (4.3 and 3.5 ng/mL, respectively; P = 0.003). There was an association between suPAR levels and disease severity in pneumonia patients. suPAR values were higher in patients with severe pneumonia than mild pneumonia (5.5 and 3.6 ng/mL, respectively; P < 0.001). Conclusion: We have shown that suPAR levels increased in patients with LTRIs and suPAR values were higher in patients with severe pneumonia than mild pneumonia. Further studies with large case series are needed to clarify the role of suPAR levels in children with LTRIs. [ABSTRACT FROM AUTHOR]

Background: Lung ultrasonography is a new method for diagnosing community-acquired pneumonia. Lung ultrasonography has some advantages over chest X-ray, such as lack of ionizing radiation risk, bedside performance, and cost-effectiveness. Objectives: In this study, we aimed to determine the feasibility of lung ultrasonography in emergency settings in children with community-acquired pneumonia. Methods: The study included patients younger than 18 years of age with suspicion of community-acquired pneumonia. On the first evaluation, patients with positive clinical and/or chest X-ray findings were defined to have community-acquired pneumonia, and this was accepted as the gold standard. The chest X-rays were evaluated by the chief of the pediatric emergency department, who was blinded to the patients and the lung ultrasonography results. Lung ultrasonography was performed by another pediatric emergency physician who was also blinded to the chest X-ray results and clinical findings such as fever, respiratory distress, rales, and wheezing. Results: Of the 91 patients enrolled, 71 (78.0%) were diagnosed with community-acquired pneumonia based on clinical and chest X-ray findings. The median (interquartile range) duration of the lung ultrasonography procedure was 4.0 (3.5–6.0) min. Shred sign, air bronchogram, and hepatization were significantly more frequent in the patients with community-acquired pneumonia (p < 0.01, p < 0.01, and p = 0.01, respectively). Sensitivity and specificity of lung ultrasonography were 78.5% (67.1–87.4) and 95.2% (76.1–99.8), respectively. Conclusion: Lung ultrasonography is a useful diagnostic method for children with suspicion of community-acquired pneumonia. [ABSTRACT FROM AUTHOR]
