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: Acute appendicitis is one of the most common abdominal emergencies. Despite all improvements in diagnostic techniques, there are still ongoing problems as proper diagnosis, misdiagnosis and perforated appendicitis. The aim of this study is to demonstrate the clinical value of IMA in patients with appendicitis and to determine the accurate diagnosis of appendicitis in clinically suspected patients. Methods: Pediatric patients with acute abdominal pain who had the Pediatric Appendicitis Score (PAS) ≥ 7 (n = 109) and a control group of 35 patients were included in this prospective case–control study. Patients were divided into two groups: patients with appendicitis (pathologically confirmed) (n = 78) and no appendicitis (n = 31). No appendicitis included observation patients and negative appendectomy. Serum samples were collected for routine laboratory parameters and IMA before surgery. Results: Patients with appendicitis had significantly higher IMA levels than no appendicitis and control groups (p = 0.001 and p < 0.001; respectively). Moreover, patients with negative appendectomy had significantly lower IMA levels than patients with appendicitis (p = 0.009). IMA and PAS were used together, and in the ROC analysis, we obtained 0.81 AUC for PAS and 0.89 AUC for PAS and IMA. Conclusion: The current study indicated that IMA is a reliable marker for accurate diagnosis of appendicitis. The combination of IMA with PAS score has been shown to facilitate the diagnosis of appendicitis. [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]

• Approximately one out of every four seizure patients experience seizure recurrence in the emergency department. • A febrile seizure, cluster seizures, structural abnormalities and not receiving benzodiazepine therapy are risk factors. • Most seizure recurrences occur within the first 6 hours regardless of risk factors. • The first six hours of observation seem to be enough for acute seizure recurrence. Afebrile seizures are the common causes of emergency department (ED) admissions in childhood, and there is limited data on the observation period in emergency service follow-up of these patients in terms of seizure recurrence in the literature. This study aims to determine the seizure recurrence time in afebrile seizures and the risk factors that determine it. Patients aged between 1 month and 18 years with afebrile seizures were included in the study. Seizure recurrence times, demographic data, diagnosis of epilepsy, use of antiseizure medications, Electroencephalography (EEG) and imaging results, structural abnormalities, hospitalizations, and treatments were recorded. The median age of 623 patients included in the study was 42 months (16.0–94.0 months) and 59.9% were male. Epilepsy was diagnosed in 372 (59.7%) of the patients. Short-acting benzodiazepine was administered in 249 of the cases. The mean observation time of the patients was 36 hours (24–98 hours). Electroencephalography (EEG) was applied in 437 (70.1%) of the patients and abnormality was detected in 53.5%. Seizure recurrence was observed in 149 patients (23.9%). The median time of seizure recurrence was 1.0 hour (0.5–4.0 hours). Eighty-six percent of the seizure recurrences (n = 129) occurred within the first six hours and 95.3% (n = 142) within the first 12 hours. Risk factors included a history of febrile seizures (p = 0.001, OR = 2.7), not receiving short-acting benzodiazepine therapy (p = 0.026, OR 1.7), previous structural abnormalities (p = 0.018, OR 1.8), and cluster seizures (p = 0.001, OR 6.7) for all patients and also EEG abnormalities in pediatric ED for first seizure (p = 0.012, OR 2.4). Patients with a history of febrile seizure, previous structural abnormalities, cluster seizures, EEG abnormalities in pediatric ED, and patients who didn't receive BZD treatment were at risk for seizure recurrence in the early period. Since most seizure recurrences occur within the first 6 hours, this period is the most critical time for recurrence risk. [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]

Aim: We aimed to describe which clinical characteristics were associated with the outcome of tracheostomy in our tertiary care pediatric intensive care unit. Material and Methods: This was a retrospective review of medical records of pediatric patients who underwent tracheostomy in our Pediatric Intensive Care unit from 2008 to 2014 in Turkey. Results: Sixty-three patients were included the study. The median age of patients was 11 (range, 1-195) months. Twenty-five (39.7%) patients were female. The tracheostomy rate was 8.5% over a six-year period. Forty-nine (77.7%) patients were able to be discharged and sent home. The decannulation rate was 12.6% (n=8). The indications for tracheostomy were upper airway obstruction (n=9) and prolonged mechanical ventilation (n=54). The median intubation period before tracheostomy was 32 (range, 1-122) days and the median duration of pediatric intensive care unit stay after tracheostomy was 37 days. A total of 21 (52.5%) patients were weaned off mechanical ventilation. The rate of successful weaning from mechanical ventilation was higher in patients with upper airway obstruction than in those in the prolonged mechanical ventilation group (p=0.021). The complication rate was 25.3% in the pediatric intensive care unit and 11.1% at home. Conclusions: Tracheostomy seems safe and improves pediatric patients' outcomes. The most important factor that affects the prognosis of children who underwent tracheostomy is the indication for tracheostomy. The outcomes are always better if the tracheostomy has been performed because of upper airway obstruction. Performing tracheostomy helps weaning from and off ventilator support and finally the discharge of patients with prolonged mechanical ventilation from the pediatric intensive care unit setting.

Objective: Heart rate, respiratory rate, arterial blood pressure, pulse oximetry, urine ouput, and lactate level are the most important parameters in the follow-up of the critically ill child who is admitted to the pediatric emergency department. The aim of this study is to determine if there is an advantage of follow-up with cerebral and splanchnic regional tissue saturation (rSO2) over routine monitoring systems in children who applied to the pediatric emergency department with manifestations of acute respiratory failure or shock. Method: Children admitted to pediatric emergency department between May 2014 and March 2016 with acute respiratory failure or shock were prospectively included into this study. The cerebral and splanchnic rSO2 levels were recorded via NIRS monitor (INVOS 510°C cerebral/somatic oximetre Covidien, Mansfield, MA, USA) in addition to conventional monitoring parameters (heart rate, respiratory rate, pulse oxymeter, and arterial blood pressure). Prez-, and post-treatment values of the patients were compared with Wilcoxon Signed Rank test. Statistical significance was accepted as p<0.05 for all tests. Results: Fifteen children were included into this study. The median age of the patients was 16.0 (10.0-66.0) months. The respiratory rate and hearth rate decreased significantly (p=0.02 and p=0.03, respectively) whereas SpO2 and splanchnic rSO2 increased (p=0.01 and p=0.04, respectively). A significant difference was not seen in cerebral rSO2 and cerebral/splanchnic rSO2 ratio (p<0.05). Conclusion: In this study, we showed that the splanchnic rSO2 values in critically ill children increased after the treatment. [ABSTRACT FROM AUTHOR]

Objective: Acute traumatic coagulopathy occurs after trauma with impairment of hemostasis and activation of fibrinolysis. Some endogenous substances may play roles in this failure of the coagulation system. Extracellular histone is one such molecule that has recently attracted attention. This study investigated the association between plasma histone-complexed DNA (hcDNA) fragments and coagulation abnormalities in pediatric trauma patients. Materials and Methods: This prospective case-control study was conducted in pediatric patients with trauma. Fifty trauma patients and 30 healthy controls were enrolled. Demographic data, anatomic injury characteristics, coagulation parameters, computerized tomography findings, trauma, and International Society on Thrombosis and Haemostasis disseminated intravascular coagulation (ISTH DIC) scores were recorded. Blood samples for hcDNA were collected and assessed by enzyme-linked immunosorbent assay. Results: Thirty-two patients had multiple trauma, while 18 patients had isolated brain injury. hcDNA levels were significantly higher in trauma patients than healthy controls (0.474 AU and 0.145 AU, respectively). There was an association between plasma hcDNA levels and trauma severity. Thirteen patients had acute coagulopathy of trauma shock (ACoTS). ACoTS patients had higher plasma histone levels than those without ACoTS (0.703 AU and 0.398 AU, respectively). Plasma hcDNA levels were positively correlated with the ISTH DIC score and length of stay in the intensive care unit and were negatively correlated with fibrinogen level. Conclusion: This study indicated that hcDNA levels were increased in pediatric trauma patients and associated with the early phase of coagulopathy. Further studies are needed to clarify the role of hcDNA levels in mortality and disseminated intravascular coagulation. [ABSTRACT FROM AUTHOR]

Percutaneous nephrostomy is a well-known therapy for urinary drainage in patients with supravesical urinary tract obstruction. This procedure which was firstly applied by Goodwin et al in 1955 is known to be performed in patients with various urologie problems for many years, especially in adults. Percutaneous nephrostomy has generally been performed by urologists or interventional radiologists and it is recognized as a difficult procedure to apply, especially in the neonatal period. As discussed in this neonatal case, PN have a very effective role in the diagnosis and management of neonatal hydronephrosis, even it might be a life-saving procedure which can also be performed by an experienced pediatric ncphrologist.
