Abstract
BACKGROUND AND OBJECTIVES Despite its routine use, it is unclear whether chest radiograph (CXR) is a cost-effective strategy in the workup of community-acquired pneumonia (CAP) in the pediatric emergency department (ED). We sought to assess the costs of CAP episodes with and without CXR among children discharged from the ED. METHODS This was a retrospective cohort study within the Healthcare Cost and Utilization Project State ED and Inpatient Databases of children aged 3 months to 18 years with CAP discharged from any EDs in 8 states from 2014 to 2019. We evaluated total 28-day costs after ED discharge, including the index visit and subsequent care. Mixed-effects linear regression models adjusted for patient-level variables and illness severity were performed to evaluate the association between CXR and costs. RESULTS We evaluated 225c781 children with CAP, and 86.2% had CXR at the index ED visit. Median costs of the 28-day episodes, index ED visits, and subsequent visits were $314 (interquartile range [IQR] 208-497), $288 (IQR 195-433), and $255 (IQR 133-637), respectively. There was a $33 (95% confidence interval [CI] 22-44) savings over 28-days per patient for those who received a CXR compared with no CXR after adjusting for patient-level variables and illness severity. Costs during subsequent visits ($26 savings, 95% CI 16-36) accounted for the majority of the savings as compared with the index ED visit ($6, 95% CI 3-10). CONCLUSIONS Performance of CXR for CAP diagnosis is associated with lower costs when considering the downstream provision of care among patients who require subsequent health care after initial ED discharge.

Abstract
BACKGROUND Viral bronchiolitis is a common condition and a leading cause of hospitalization in young children. OBJECTIVE This article provides readers with an update on the evaluation, diagnosis, and treatment of viral bronchiolitis, primarily due to RSV. METHODS A PubMed search was conducted in December 2021 in Clinical Queries using the key terms "acute bronchiolitis" OR "respiratory syncytial virus infection". The search included clinical trials, randomized controlled trials, case control studies, cohort studies, meta-analyses, observational studies, clinical guidelines, case reports, case series, and reviews. The search was restricted to children and English literature. The information retrieved from the above search was used in the compilation of this article. RESULTS Respiratory syncytial virus (RSV) is the most common viral bronchiolitis in young children. Other viruses such as human rhinovirus and coronavirus could be etiological agents. Diagnosis is based on clinical manifestation. Viral testing is useful only for cohort and quarantine purposes. Cochrane evidence-based reviews have been performed on most treatment modalities for RSV and viral bronchiolitis. Treatment for viral bronchiolitis is mainly symptomatic support. Beta-agonists are frequently used despite the lack of evidence that they reduce hospital admissions or length of stay. Nebulized racemic epinephrine, hypertonic saline and corticosteroids are generally not effective. Passive immunoprophylaxis with a monoclonal antibody against RSV, when given intramuscularly and monthly during winter, is effective in preventing severe RSV bronchiolitis in high-risk children who are born prematurely and in children under 2 years with chronic lung disease or hemodynamically significant congenital heart disease. Vaccines for RSV bronchiolitis are being developed. Children with viral bronchiolitis in early life are at increased risk of developing asthma later in childhood. CONCLUSION Viral bronchiolitis is common. No current pharmacologic treatment or novel therapy has been proven to improve outcomes compared to supportive treatment. Viral bronchiolitis in early life predisposes asthma development later in childhood.

Front Digit Health 2023; 5:1104604. [PMID: 36910570 PMCID: PMC9992200 DOI: 10.3389/fdgth.2023.1104604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 01/16/2023] [Indexed: 02/25/2023] Open
Abstract
Objective Chest radiographs are frequently used to diagnose community-acquired pneumonia (CAP) for children in the acute care setting. Natural language processing (NLP)-based tools may be incorporated into the electronic health record and combined with other clinical data to develop meaningful clinical decision support tools for this common pediatric infection. We sought to develop and internally validate NLP algorithms to identify pediatric chest radiograph (CXR) reports with pneumonia. Materials and methods We performed a retrospective study of encounters for patients from six pediatric hospitals over a 3-year period. We utilized six NLP techniques: word embedding, support vector machines, extreme gradient boosting (XGBoost), light gradient boosting machines Naïve Bayes and logistic regression. We evaluated their performance of each model from a validation sample of 1,350 chest radiographs developed as a stratified random sample of 35% admitted and 65% discharged patients when both using expert consensus and diagnosis codes. Results Of 172,662 encounters in the derivation sample, 15.6% had a discharge diagnosis of pneumonia in a primary or secondary position. The median patient age in the derivation sample was 3.7 years (interquartile range, 1.4-9.5 years). In the validation sample, 185/1350 (13.8%) and 205/1350 (15.3%) were classified as pneumonia by content experts and by diagnosis codes, respectively. Compared to content experts, Naïve Bayes had the highest sensitivity (93.5%) and XGBoost had the highest F1 score (72.4). Compared to a diagnosis code of pneumonia, the highest sensitivity was again with the Naïve Bayes (80.1%), and the highest F1 score was with the support vector machine (53.0%). Conclusion NLP algorithms can accurately identify pediatric pneumonia from radiography reports. Following external validation and implementation into the electronic health record, these algorithms can facilitate clinical decision support and inform large database research.

Immune and endothelial activation markers and risk stratification of childhood pneumonia in Uganda: A secondary analysis of a prospective cohort study. PLoS Med 2022; 19:e1004057. [PMID: 35830474 PMCID: PMC9328519 DOI: 10.1371/journal.pmed.1004057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 07/27/2022] [Accepted: 06/23/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Despite the global burden of pneumonia, reliable triage tools to identify children in low-resource settings at risk of severe and fatal respiratory tract infection are lacking. This study assessed the ability of circulating host markers of immune and endothelial activation quantified at presentation, relative to currently used clinical measures of disease severity, to identify children with pneumonia who are at risk of death. METHODS AND FINDINGS We conducted a secondary analysis of a prospective cohort study of children aged 2 to 59 months presenting to the Jinja Regional Hospital in Jinja, Uganda between February 2012 and August 2013, who met the Integrated Management of Childhood Illness (IMCI) diagnostic criteria for pneumonia. Circulating plasma markers of immune (IL-6, IL-8, CXCL-10/IP-10, CHI3L1, sTNFR1, and sTREM-1) and endothelial (sVCAM-1, sICAM-1, Angpt-1, Angpt-2, and sFlt-1) activation measured at hospital presentation were compared to lactate, respiratory rate, oxygen saturation, procalcitonin (PCT), and C-reactive protein (CRP) with a primary outcome of predicting 48-hour mortality. Of 805 children with IMCI pneumonia, 616 had severe pneumonia. Compared to 10 other immune and endothelial activation markers, sTREM-1 levels at presentation had the best predictive accuracy in identifying 48-hour mortality for children with pneumonia (AUROC 0.885, 95% CI 0.841 to 0.928; p = 0.03 to p < 0.001) and severe pneumonia (AUROC 0.870, 95% CI 0.824 to 0.916; p = 0.04 to p < 0.001). sTREM-1 was more strongly associated with 48-hour mortality than lactate (AUROC 0.745, 95% CI 0.664 to 0.826; p < 0.001), respiratory rate (AUROC 0.615, 95% CI 0.528 to 0.702; p < 0.001), oxygen saturation (AUROC 0.685, 95% CI 0.594 to 0.776; p = 0.002), PCT (AUROC 0.650, 95% CI 0.566 to 0.734; p < 0.001), and CRP (AUROC 0.562, 95% CI 0.472 to 0.653; p < 0.001) in cases of pneumonia and severe pneumonia. The main limitation of this study was the unavailability of radiographic imaging. CONCLUSIONS In this cohort of Ugandan children, sTREM-1 measured at hospital presentation was a significantly better indicator of 48-hour mortality risk than other common approaches to risk stratify children with pneumonia. Measuring sTREM-1 at clinical presentation may improve the early triage, management, and outcome of children with pneumonia at risk of death. TRIAL REGISTRATION The trial was registered at clinicaltrial.gov (NCT04726826).

Abstract
BACKGROUND/OBJECTIVES Chest radiograph (CXR) is routinely performed among children with suspected pneumonia, though it is not clear how specific radiographic findings impact antibiotic treatment for pneumonia. We evaluated the impact of viral radiographic features on antibiotic treatment among children undergoing pneumonia evaluation in the emergency department (ED). METHODS Children presenting to a pediatric ED who underwent a CXR for pneumonia evaluation were prospectively enrolled. Prior to CXR performance, physicians indicated their level of suspicion for pneumonia. The CXR report was reviewed to assess for the presence of viral features (peribronchial cuffing, perihilar markings, and interstitial infiltrate) as well as radiographic features suggestive of pneumonia (consolidation, infiltrate, and opacity). The relationship between viral radiographic features and antibiotic treatment was assessed based on the level of clinical suspicion for pneumonia prior to CXR. RESULTS Patients with normal CXRs (n = 400) and viral features alone (n = 370) were managed similarly, with 8.0% and 8.6% of patients receiving antibiotic treatment, respectively (P = .75). Compared with children with radiographic pneumonia (n = 174), patients with concurrent viral features and radiographic pneumonia (n = 177) were treated with antibiotics less frequently (86.2% vs 54.3%, P < .001). Among children with isolated viral features on CXR, antibiotic treatment rates were correlated with pre-CXR level of suspicion for pneumonia. CONCLUSIONS Among children with suspected pneumonia, the presence of viral features alone on CXR is not associated with increased rates of antibiotic use. Among children with radiographic pneumonia, the addition of viral features on CXR is associated with lower rates of antibiotic use, as compared to children with radiographic pneumonia alone.

Significance of Sonographic Subcentimeter, Subpleural Consolidations in Pediatric Patients Evaluated for Pneumonia. J Pediatr 2022; 243:193-199.e2. [PMID: 34968499 DOI: 10.1016/j.jpeds.2021.12.052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 11/19/2021] [Accepted: 12/22/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVES To investigate the rates of radiographic pneumonia and clinical outcomes of children with suspected pneumonia and subcentimeter, subpleural consolidations on point-of-care lung ultrasound. STUDY DESIGN We enrolled a prospective convenience sample of children aged 6 months to 18 years undergoing chest radiography (CXR) for pneumonia evaluation in a single tertiary-care pediatric emergency department. Point-of-care lung ultrasound was performed by an emergency medicine physician with subsequent expert review. We determined rates of radiographic pneumonia and clinical outcomes in the children with subcentimeter, subpleural consolidations, stratified by the presence of larger (>1 cm) sonographic consolidations. The children were followed prospectively for 2 weeks to identify a delayed diagnosis of pneumonia. RESULTS A total of 188 patients, with a median age of 5.8 years (IQR, 3.5-11.0 years), were evaluated. Of these patients, 62 (33%) had subcentimeter, subpleural consolidations on lung ultrasound, and 23 (37%) also had larger (>1 cm) consolidations. Patients with subcentimeter, subpleural consolidations and larger consolidations had the highest rates of definite radiographic pneumonia (61%), compared with 21% among children with isolated subcentimeter, subpleural consolidations. Overall, 23 children with isolated subcentimeter, subpleural consolidations (59%) had no evidence of pneumonia on CXR. Among 16 children with isolated subcentimeter, subpleural consolidations and not treated with antibiotics, none had a subsequent pneumonia diagnosis within the 2-week follow-up period. CONCLUSIONS Children with subcentimeter, subpleural consolidations often had radiographic pneumonia; however, this occurred most frequently when subcentimeter, subpleural consolidations were identified in combination with larger consolidations. Isolated subcentimeter, subpleural consolidations in the absence of larger consolidations should not be viewed as synonymous with pneumonia; CXR may provide adjunctive information in these cases.

Abstract
BACKGROUND We aimed to determine the impact of utilizing a rapid panel test of respiratory viral and atypical bacteria (FilmArray® Respiratory Panel, FA RP) on etiological diagnosis of acute lower respiratory infection (ALRI) and antimicrobial stewardship in critical care pediatric patients. METHODS Prospective cohort study of patients aged<18 years with clinical diagnosis of ALRI that were admitted to the Pediatric Intensive Care Unit (PICU) of Hospital Sant Joan de Deu (Barcelona, Spain) during December 2015-February 2017. Patients were diagnosed by FA RP and by a bundle of routine microbiological assays. RESULTS ALRI viral and bacterial etiology was confirmed by a composite reference standard of routine microbiological assays in 72 (55.4%) and 15 (11.5%) respiratory samples, respectively, that were collected from 130 children (median age, 3.5 months, IQR 1.1-14.8 months; 54.6% male). Comparatively, FA RP use increased etiological confirmation of ALRI in up to 123 (94.6%) samples (p<0.001) but only determined a bacterial origin in 2 (1.5%). Availability of diagnostic results before patient discharge from the PICU rose from 65.4 to 38.5% (p<0.001). Use of the new panel test directly influenced antimicrobial stewardship in 11 (8.4%) episodes, leading to discontinuation of antiviral drugs (n=5), administration of targeted antibiotics (n=3), antiviral therapy start (n=2) and both targeted antibiotic administration and discontinuation of antiviral drugs (n=1). CONCLUSION FA RP contributed to improve etiological diagnosis of ALRI in a timely manner while enhancing a more rational use of antimicrobial drugs in critical care pediatric patients.

Abstract
INTRODUCTION Clinically diagnosed pneumonia in children is a leading cause of paediatric hospitalisation and mortality. The aetiology is usually bacterial or viral, but malaria can cause a syndrome indistinguishable from clinical pneumonia. There is no method with high sensitivity to detect a bacterial infection in these patients and, as result, antibiotics are frequently overprescribed. Conversely, unrecognised concomitant bacterial infection in patients with malarial infections occur with omission of antibiotic therapy from patients with bacterial infections. Previously, we identified two combinations of blood proteins with 96% sensitivity and 86% specificity for detecting bacterial disease. The current project aimed to validate and improve these combinations by evaluating additional biomarkers in paediatric patients with clinical pneumonia. Our goal was to describe combinations of a limited number of proteins with high sensitivity and specificity for bacterial infection to be incorporated in future point-of-care tests. Furthermore, we seek to explore signatures to prognosticate clinical pneumonia. METHODS AND ANALYSIS Patients (n=900) aged 2-59 months presenting with clinical pneumonia at two Gambian hospitals will be enrolled and classified according to criteria for definitive bacterial aetiology (based on microbiological tests and chest radiographs). We will measure proteins at admission using Luminex-based immunoassays in 90 children with definitive and 160 with probable bacterial aetiology, and 160 children classified according to the prognosis of their disease. Previously identified diagnostic signatures will be assessed through accuracy measures. Moreover, we will seek new diagnostic and prognostic signatures through machine learning methods, including support vector machine, penalised regression and classification trees. ETHICS AND DISSEMINATION Ethics approval has been obtained from the Gambia Government/Medical Research Council Unit The Gambia Joint Ethics Committee (protocol 1616) and the institutional review board of Boston University Medical Centre (STUDY00000958). Study results will be disseminated to the staff of the study hospitals, in scientific seminars and meetings, and in publications. TRIAL REGISTRATION NUMBER H-38462.

CHILDREN (BASEL, SWITZERLAND) 2021; 8:659. [PMID: 34438550 PMCID: PMC8391397 DOI: 10.3390/children8080659] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 07/16/2021] [Accepted: 07/26/2021] [Indexed: 12/02/2022]
Abstract
BACKGROUND Pneumonia is the leading cause of death among children; thus, a correct early diagnosis would be ideal. The imagistic diagnosis still uses chest X-ray (CXR), but lung ultrasound (LUS) proves to be reliable for pneumonia diagnosis. The aim of our study was to evaluate the sensitivity and specificity of LUS compared to CXR in consolidated pneumonia. METHODS Children with clinical suspicion of bacterial pneumonia were screened by LUS for pneumonia, followed by CXR. The agreement relation between LUS and CXR regarding the detection of consolidation was evaluated by Cohen's kappa test. RESULTS A total of 128 patients with clinical suspicion of pneumonia were evaluated; 74 of them were confirmed by imagery and biological inflammatory markers. The highest frequency of pneumonia was in the 0-3 years age group (37.83%). Statistical estimation of the agreement between LUS and CXR in detection of the consolidation found an almost perfect agreement, with a Cohen's kappa coefficient of K = 0.89 ± 0.04 SD, p = 0.000. Sensitivity of LUS was superior to CXR in detection of consolidations. CONCLUSION Lung ultrasound is a reliable method for the detection of pneumonia consolidation in hospitalized children, with sensitivity and specificity superior to CXR. LUS should be used for rapid and safe evaluation of child pneumonia.

Pediatr Pulmonol 2021; 56:1018-1025. [PMID: 33085218 DOI: 10.1002/ppul.25127] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 09/10/2020] [Accepted: 10/09/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND Lung ultrasound (LUS) has been successfully used in the diagnosis of different pulmonary diseases. Present study design to determine the diagnostic value of LUS in the evaluation of children with novel coronavirus disease 2019 (COVID-19). METHODS AND OBJECTIVES Prospective multicenter study, 40 children with confirmed COVID-19 were included. LUS was performed to all patients at admission. The chest X-ray and computed tomography (CT) were performed according to the decision of the primary physicians. LUS results were compared with chest X-ray and CT findings and diagnostic performance was determined. RESULTS Of the 40 children median (range) was 10.5 (0.4-17.8) years. Chest X-ray and LUS were performed on all and chest CT was performed on 28 (70%) patients at the time of diagnosis. Sixteen (40%) patients had no apparent chest CT abnormalities suggestive of COVID-19, whereas 12 (30%) had abnormalities. LUS confirmed the diagnosis of pulmonary involvement in 10 of 12 patients with positive CT findings. LUS demonstrated normal lung patterns among 15 of 16 patients who had normal CT features. The sensitivity and the area under the receiver operating characteristics (ROC) curve (area under the ROC curve) identified by the chest X-ray and LUS tests were compared and statistically significantly different (McNemar's test: p = .016 and p = .001 respectively) detected. Chest X-ray displayed false-negative results for pulmonary involvement in 75% whereas for LUS it was 16.7%. CONCLUSIONS LUS might be a useful tool in the diagnostic steps of children with COVID-19. A reduction in chest CT assessments may be possible when LUS is used in the initial diagnostic steps for these children.

Abstract
Background An infectious disease caused by a new type of coronavirus that can manifest as an acute respiratory infection was discovered in China in mid-December 2019 and soon spread throughout the country and to the rest of the world. Although chest X-rays are the initial imaging technique of choice for low respiratory infections with or without dyspnea, few articles have reported the radiologic findings in children with COVID-19. Objective To describe the clinical, laboratory, and chest X-ray findings in pediatric patients with signs and symptoms of respiratory infection attended at our hospital in March 2020. To analyze the frequency of COVID-19 compared to other respiratory infections, and to describe the radiologic manifestations of COVID-19 in pediatric patients. Material and methods This cross-sectional observational study included all children with clinical manifestations of respiratory infection (fever, rhinorrhea, cough, and/or dyspnea) that required chest X-rays in our hospital between March 1 and March 31. Results A total of 231 pediatric patients (90 (39%) girls and 141 (61%) boys; mean age, 4 y, range 1 month–16 years) underwent chest X-rays for suspected respiratory infections. Most (88.4%) had mild symptoms; 29.9% had a family member positive for COVID-19 with symptoms similar to those of the patient. Nasal and/or throat swabs were analyzed for SARS-CoV-2 with PCR in the 47 (20.3%) children who presented at the emergency department; 3 (6.3%) of these were positive. Microbiological analyses were done in 85 (36.8%) of all patients, finding infections due to pathogens other than SARS-CoV-2 in 30 (35.3%). One of the patients with a PCR positive for SARS-CoV-2 had urine infection due to E. coli and blood culture positive for S. viridans. Abnormalities were observed on X-rays in 73.2% of the patients. Peribronchial thickening was the most common abnormal finding, observed in 57% of patients. Parenchymal consolidations were observed in 38.5%, being bilateral in 29.2% and associated with pleural effusion in 3.3%. The interstitial lines were thickened in 7.3%, and 7.3% had ground-glass opacities. Conclusion During March 2020, COVID-19 and other symptomatic respiratory infections were observed. The radiologic pattern of these infections is nonspecific, and chest X-rays alone are insufficient for the diagnosis. Children with clinical manifestations compatible with COVID-19 (with or without PCR confirmation of infection by SARS-CoV-2) had mild symptoms and most did not require admission or invasive mechanical ventilation. In a context of community transmission, the absence of a known epidemiological antecedent should not be a contraindication for PCR to detect SARS-CoV-2.

Manifestations and Risk Factors in Children Hospitalized with Respiratory Syncytial Virus Infection. ARCHIVES OF PEDIATRIC INFECTIOUS DISEASES 2020.

Abstract
Background: Acute lower respiratory infection (ALRI) is one of the main causes of morbidity and mortality in children under five years of age, and the respiratory syncytial virus (RSV) remains its leading etiological factor. Although RSV infections occur in all age groups, the most severe course is observed among children. The clinical manifestations include both mild upper respiratory infections and severe infections of the lower tract, such as bronchiolitis and pneumonia that can lead to hospitalization and severe complications, including respiratory failure. Objectives: The study aimed to evaluate the manifestations of RSV infection in hospitalized children younger than 18 months of age and predictors of disease severity, as well as their comparison with the same age group hospitalized due to ALRI of different etiology. Methods: A retrospective analysis was performed on medical records of 448 children hospitalized due to ALRI. The analysis was performed on the total study group and subgroups of children with positive and negative results of the nasal swab for RSV detection. In each group, clinical data, laboratory test results, and imaging results were analyzed. Results: The most common manifestation was pneumonia (n = 82; 63.08%). Otitis media was observed mainly in children under six months of age with lowered inflammatory markers (P < 0.05), conjunctivitis in those with a positive family history of allergies (P < 0.05), and pneumonia in children under six months of age, with lower blood oxygen saturation and inflammatory markers, features of acidosis, and fever-free course (P < 0.05). Respiratory failure affected 13 children (10%). However, no predictors of this complication were noted. Conclusions: As pneumonia was the most common manifestation in children with both RSV-positive and RSV-negative ALRI, it seems advisable to perform the imaging of the lungs on admission and carefully monitor the child’s condition during hospitalization. In both groups, special attention should be paid to the youngest children with low inflammatory markers on hospital admission, increased clinical symptoms, and family history of allergies. Nevertheless, widely known risk factors of RSV infection itself do not reflect the risk of developing pneumonia or respiratory failure in its course.

Abstract
STUDY OBJECTIVE Acute chest syndrome is a leading cause of mortality in patients with sickle cell disease (SCD). Because early detection of acute chest syndrome is directly tied to prognosis, young patients with SCD undergo countless chest radiography screenings throughout their lifetime for commonly occurring acute chest syndrome risk factors such as fever, chest pain, or cough. Chest radiography is not an ideal screening method because it is associated with radiation exposure, which accumulates with repeated imaging. Point-of-care lung ultrasonography is a nonradiating imaging modality that has been used to identify other lung pathology and may have a role in SCD. The goal of this study was to determine the accuracy of point-of-care lung ultrasound to identify an infiltrate suggestive of acute chest syndrome in patients with SCD compared to chest radiography as the gold standard. METHODS This was a prospective observational study in 2 urban pediatric emergency departments to evaluate the accuracy of point-of-care lung ultrasonography in identifying patients with SCD who were aged 0 to 21 years and had an infiltrate suggestive of acute chest syndrome compared with chest radiography. Clinicians and trainees with point-of-care lung ultrasonographic training obtained informed consent and performed investigational point-of-care lung ultrasonography to evaluate for lung consolidation. A blinded point-of-care lung ultrasonographic expert reviewed results for quality assurance and agreement. Accuracy, sensitivity, specificity, likelihood ratios, and positive and negative predictive value were calculated for point-of-care lung ultrasonography test performance characteristics, with chest radiography as a reference standard. RESULTS Point-of-care lung ultrasonography was performed on 191 SCD patients with a mean age of 8 years; 41% were female patients, and there was a 17% prevalence of acute chest syndrome. Accuracy of point-of-care lung ultrasonography to detected acute chest syndrome was 92%, sensitivity was 88%, and specificity was 93% compared with that for chest radiography. CONCLUSION Point-of-care lung ultrasonography is a feasible alternative to chest radiography for screening for acute chest syndrome in young patients with SCD. Further studies are needed to determine how this test performs within clinical practice.

Diagnosis of common pulmonary diseases in children by X-ray images and deep learning. Sci Rep 2020; 10:17374.

Abstract
Acute lower respiratory infection is the leading cause of child death in developing countries. Current strategies to reduce this problem include early detection and appropriate treatment. Better diagnostic and therapeutic strategies are still needed in poor countries. Artificial-intelligence chest X-ray scheme has the potential to become a screening tool for lower respiratory infection in child. Artificial-intelligence chest X-ray schemes for children are rare and limited to a single lung disease. We need a powerful system as a diagnostic tool for most common lung diseases in children. To address this, we present a computer-aided diagnostic scheme for the chest X-ray images of several common pulmonary diseases of children, including bronchiolitis/bronchitis, bronchopneumonia/interstitial pneumonitis, lobar pneumonia, and pneumothorax. The study consists of two main approaches: first, we trained a model based on YOLOv3 architecture for cropping the appropriate location of the lung field automatically. Second, we compared three different methods for multi-classification, included the one-versus-one scheme, the one-versus-all scheme and training a classifier model based on convolutional neural network. Our model demonstrated a good distinguishing ability for these common lung problems in children. Among the three methods, the one-versus-one scheme has the best performance. We could detect whether a chest X-ray image is abnormal with 92.47% accuracy and bronchiolitis/bronchitis, bronchopneumonia, lobar pneumonia, pneumothorax, or normal with 71.94%, 72.19%, 85.42%, 85.71%, and 80.00% accuracy, respectively. In conclusion, we provide a computer-aided diagnostic scheme by deep learning for common pulmonary diseases in children. This scheme is mostly useful as a screening for normal versus most of lower respiratory problems in children. It can also help review the chest X-ray images interpreted by clinicians and may remind possible negligence. This system can be a good diagnostic assistance under limited medical resources.

Abstract
BACKGROUND We aimed to determine the impact of utilizing a rapid panel test of respiratory viral and atypical bacteria (FilmArray® Respiratory Panel, FA RP) on etiological diagnosis of acute lower respiratory infection (ALRI) and antimicrobial stewardship in critical care pediatric patients. METHODS Prospective cohort study of patients aged<18 years with clinical diagnosis of ALRI that were admitted to the Pediatric Intensive Care Unit (PICU) of Hospital Sant Joan de Deu (Barcelona, Spain) during December 2015-February 2017. Patients were diagnosed by FA RP and by a bundle of routine microbiological assays. RESULTS ALRI viral and bacterial etiology was confirmed by a composite reference standard of routine microbiological assays in 72 (55.4%) and 15 (11.5%) respiratory samples, respectively, that were collected from 130 children (median age, 3.5 months, IQR 1.1-14.8 months; 54.6% male). Comparatively, FA RP use increased etiological confirmation of ALRI in up to 123 (94.6%) samples (p<0.001) but only determined a bacterial origin in 2 (1.5%). Availability of diagnostic results before patient discharge from the PICU rose from 65.4 to 38.5% (p<0.001). Use of the new panel test directly influenced antimicrobial stewardship in 11 (8.4%) episodes, leading to discontinuation of antiviral drugs (n=5), administration of targeted antibiotics (n=3), antiviral therapy start (n=2) and both targeted antibiotic administration and discontinuation of antiviral drugs (n=1). CONCLUSION FA RP contributed to improve etiological diagnosis of ALRI in a timely manner while enhancing a more rational use of antimicrobial drugs in critical care pediatric patients.

Abstract
Pneumonia is a life-threatening disease, which occurs in the lungs caused by either bacterial or viral infection. It can be life-endangering if not acted upon at the right time and thus the early diagnosis of pneumonia is vital. The paper aims to automatically detect bacterial and viral pneumonia using digital x-ray images. It provides a detailed report on advances in accurate detection of pneumonia and then presents the methodology adopted by the authors. Four different pre-trained deep Convolutional Neural Network (CNN): AlexNet, ResNet18, DenseNet201, and SqueezeNet were used for transfer learning. A total of 5247 chest X-ray images consisting of bacterial, viral, and normal chest x-rays images were preprocessed and trained for the transfer learning-based classification task. In this study, the authors have reported three schemes of classifications: normal vs. pneumonia, bacterial vs. viral pneumonia, and normal, bacterial, and viral pneumonia. The classification accuracy of normal and pneumonia images, bacterial and viral pneumonia images, and normal, bacterial, and viral pneumonia were 98%, 95%, and 93.3%, respectively. This is the highest accuracy, in any scheme, of the accuracies reported in the literature. Therefore, the proposed study can be useful in more quickly diagnosing pneumonia by the radiologist and can help in the fast airport screening of pneumonia patients.

Abstract
BACKGROUND AND OBJECTIVES National guidelines recommend against routine use of chest radiography (CXR) for community-acquired pneumonia (CAP) diagnosis in the pediatric emergency department (ED). Given that CXR is often used to exclude the diagnosis of CAP, a reduction in CXR use may result in overdiagnosis of CAP. We sought to evaluate trends in CXR use and assess the association between CXR performance and CAP diagnosis among children discharged from pediatric EDs. METHODS Children 3 months to 18 years of age discharged from 30 US EDs with (1) CAP or (2) fever or respiratory illness between 2008 and 2018 were included. Temporal trends in CXR use and rates of CAP diagnoses among patients with fever or respiratory illness were assessed. Correlation between hospital-level CXR use and CAP diagnosis rates were evaluated by using Spearman's correlation weighted by hospital volume. RESULTS CXR usage decreased from 86.6% to 80.4% (P < .001) for patients with CAP and from 30.4% to 18.6% (P < .001) for children with fever or respiratory illness over the 10-year study period. CAP diagnosis rates also declined from 7.8% to 5.9% (P < .001). Hospital-level CXR use was correlated with pneumonia diagnosis rates (correlation coefficient 0.58; P < .001). CONCLUSIONS Over the past decade, there has been a decline in CXR use in the ED among children with pneumonia and respiratory illnesses, with a decrease in pneumonia diagnoses over the same time period. Future studies are needed to assess the role of CXR in the evaluation of children with possible pneumonia in the ED setting.

Abstract
OBJECTIVES Point-of-care lung ultrasonography (US) is an alternative to chest radiography for imaging of suspected community-acquired pneumonia (CAP) in children. We compared pediatric emergency department (ED) time metrics between children who received point-of-care lung US versus chest radiography. Secondary objectives were comparisons of health system costs and other resources in these imaging groups. METHODS This work was a retrospective matched cohort study of children aged 0 to 18 years in an academic urban pediatric ED who were imaged for suspected CAP with either point-of-care lung US or chest radiography. RESULTS A total of 202 patients (101 in each group) were included in the study. The point-of-care lung US group spent a mean of 75.9 (SE, 14.3) minutes less from physician assessment to discharge (P < .0001) and 60.9 (SE, 18.1) minutes less in the overall ED length of stay (P = .0008). Physician billings and facility fees were both significantly lower (P < .0001) in the point-of-care lung US group, for a mean health systems savings of CAN$187.1 (SE, CAN$21.9). CONCLUSIONS In children undergoing imaging for suspected CAP in our pediatric ED, point-of-care lung US by pediatric emergency medicine physicians was associated with decreased time and cost compared with chest radiography.

Abstract
BACKGROUND Guidelines currently do not recommend the routine use of chest x-ray (CXR) in bronchiolitis. However, CXR is still performed in a high percentage of cases, mainly to diagnose or rule out pneumonia. The inappropriate use of CXR results in children exposure to ionizing radiations and increased medical costs. Lung Ultrasound (LUS) has become an emerging diagnostic tool for diagnosing pneumonia in the last decades. The purpose of this study was to assess the diagnostic accuracy and reliability of LUS for the detection of pneumonia in hospitalized children with bronchiolitis and to evaluate the agreement between LUS and CXR in diagnosing pneumonia in these patients. METHODS We enrolled children admitted to our hospital in 2016-2017 with a diagnosis of bronchiolitis and undergone CXR because of clinical suspicion of concomitant pneumonia. LUS was performed in each child by a pediatrician blinded to the patient's clinical, laboratory and CXR findings. An exploratory analysis was done in the first 30 patients to evaluate the inter-observer agreement between a pediatrician and a radiologist who independently performed LUS. The diagnosis of pneumonia was established by an expert clinician based on the recommendations of the British Thoracic Society guidelines. RESULTS Eighty seven children with bronchiolitis were investigated. A final diagnosis of concomitant pneumonia was made in 25 patients. Sensitivity and specificity of LUS for the diagnosis of pneumonia were 100% and 83.9% respectively, with an area under-the-curve of 0.92, while CXR showed a sensitivity of 96% and specificity of 87.1%. When only consolidation > 1 cm was considered consistent with pneumonia, the specificity of LUS increased to 98.4% and the sensitivity decreased to 80.0%, with an area under-the-curve of 0.89. Cohen's kappa between pediatrician and radiologist sonologists in the first 30 patients showed an almost perfect agreement in diagnosing pneumonia by LUS (K 0.93). CONCLUSIONS This study shows the good accuracy of LUS in diagnosing pneumonia in children with clinical bronchiolitis. When including only consolidation size > 1 cm, specificity of LUS was higher than CXR, avoiding the need to perform CXR in these patients. Added benefit of LUS included high inter-observer agreement.

UNLABELLED : media-1vid110.1542/5804413949001PEDS-VA_2018-0236Video Abstract BACKGROUND AND OBJECTIVES: The ability of the chest radiograph (CXR) to exclude the diagnosis of pneumonia in children is unclear. We sought to determine the negative predictive value of CXR in children with suspected pneumonia. METHODS Children 3 months to 18 years of age undergoing CXRs for suspected pneumonia in a tertiary-care pediatric emergency department (ED) were prospectively enrolled. Children currently receiving antibiotics and those with underlying chronic medical conditions were excluded. The primary outcome was defined as a physician-ascribed diagnosis of pneumonia independent of radiographic findings. CXR results were classified as positive, equivocal, or negative according to radiologist interpretation. Children with negative CXRs and without a clinical diagnosis of pneumonia were managed for 2 weeks after the ED visit. Children subsequently diagnosed with pneumonia during the follow-up period were considered to have had false-negative CXRs at the ED visit. RESULTS There were 683 children enrolled during the 2-year study period, with a median age of 3.1 years (interquartile range 1.4-5.9 years). There were 457 children (72.8%) with negative CXRs; 44 of these children (8.9%) were clinically diagnosed with pneumonia, and 42 (9.3%) were given antibiotics for other bacterial syndromes. Of the 411 children with negative CXRs who were managed without antibiotics, 5 were subsequently diagnosed with pneumonia within 2 weeks (negative predictive value of CXR 98.8%; 95% confidence interval 97.0%-99.6%). CONCLUSIONS A negative CXR excludes pneumonia in the majority of children. Children with negative CXRs and low clinical suspicion for pneumonia can be safely observed without antibiotic therapy.

Abstract
OBJECTIVE Although a clinical diagnosis, the standard initial imaging modality for patients with concern for pediatric community acquired pneumonia (pCAP) is a chest x-ray (CXR), which has a relatively high false negative rate, exposes patients to ionizing radiation, and may not be available in resource limited settings. The primary objective of this meta-analysis is to evaluate the accuracy of lung ultrasound (LUS) compared to CXR for the diagnosis of pCAP. METHODS Data were collected via a systematic review of PubMed, EMBASE, and Web of Science with dates up to August 2017. Keywords and search terms were generated for pneumonia, lung ultrasound, and pediatric population. Two independent investigators screened abstracts for inclusion. PRISMA was used for selecting appropriate studies. QUADAS was applied to these studies to assess quality for inclusion into the meta-analysis. We collected data from included studies and calculated sensitivity, specificity, positive predictive value, and negative predictive values of CXR and LUS for the diagnosis of pCAP. RESULTS Twelve studies including 1510 patients were selected for data extraction. LUS had a sensitivity of 95.5% (93.6-97.1) and specificity of 95.3% (91.1-98.3). CXR had a sensitivity of 86.8% (83.3-90.0) and specificity of 98.2% (95.7-99.6). Variations between the studies included ultrasound findings diagnostic of pneumonia, study setting (inpatient vs emergency department) and inclusion of CXR in the reference standard for pneumonia. CONCLUSIONS In our meta-analysis, lung ultrasound had significantly better sensitivity with similar specificity when compared to chest x-ray for the diagnosis of pediatric community acquired pneumonia.

Abstract
Background Early diagnosis of community-acquired pneumonia (CAP) is essential to reduce the total burden of this disease. Traditionally, chest radiography (CR) is used to identify true CAP. However, CR is not a perfect diagnostic test for CAP. The use of lung ultrasonography (LUS) has been suggested as an alternative to overcome the problems associated with CR and increase the feasibility and accuracy of CAP diagnosis. LUS has largely been used for the diagnosis of several lung problems, including CAP, in adult patients with satisfactory results. Experience with LUS in children has grown over recent years. The main aim of this paper is to discuss the advantages and limits of LUS in the diagnosis of paediatric CAP. Discussion The presence of a consolidation pattern during LUS may represent pneumonia or atelectasis, although this conclusion is operator dependent. An overall agreement between LUS and CR was observed in most of the studies that were examined. In most reports where a disagreement between the two methods was found, CR was not able to identify the cases that were correctly diagnosed by LUS, particularly when CR was performed only with postero-anterior/antero-posterior projection and consolidation was observed in lung areas that are poorly visualized by CR. However, the lack of standardized LUS methods is problematic. Finally, the real advantage of LUS for the diagnosis of CAP in children remains unclear. Summary LUS is an interesting diagnostic modality that appears a useful first imaging test in children with suspected CAP. However, the methods used to perform LUS in children are not precisely standardized, and the diagnosis of interstitial CAP is inaccurate. Further studies are needed before LUS can be routinely used in everyday paediatric practice.

Abstract
Despite recommendations against routine imaging, chest radiography (CXR) is frequently performed on infants hospitalized for bronchiolitis. We conducted a review of 811 infants hospitalized for bronchiolitis to identify clinical factors associated with imaging findings. CXR was performed on 553 (68%) infants either on presentation or during hospitalization; 466 readings (84%) were normal or consistent with viral illness. Clinical factors significantly associated with normal/viral imaging were normal temperature (odds ratio = 1.66; 95% CI = 1.03-2.67) and normal oxygen saturation (odds ratio = 1.77; 95% CI = 1.1-2.83) on presentation. Afebrile patients with normal oxygen saturations were nearly 3 times as likely to have a normal/viral CXR as patients with both fever and hypoxia. Our findings support the limited role of radiography in the evaluation of hospitalized infants with bronchiolitis, especially patients without fever or hypoxia.

Abstract
BACKGROUND Knowledge of key drivers for antibiotic prescribing in pediatric lower respiratory tract infection (LRTI) could support rational antibiotic use. Thus, we aimed to determine the impact of clinical and laboratory factors on antibiotic prescribing in children and adolescents with febrile LRTI. METHODS Pediatric patients from the standard care control group of a randomized controlled trial (ProPAED) investigating procalcitonin guided antibiotic treatment in febrile LRTI were included in a multivariate logistic regression analysis to evaluate the impact of laboratory and clinical factors on antibiotic prescribing. RESULTS The standard care control group of the ProPAED study comprised 165 LRTI patients (median age: 2.7 years, range: 0.1-16), out of which 88 (55%) received antibiotic treatment. Factors significantly associated with antibiotic prescribing in patients with complete clinical and laboratory documentation (n = 158) were C-reactive protein (OR 5.8 for a 10-fold increase, 95%CI 2.2-14.9), white blood count beyond age-dependent reference range (OR 3.9, 95%CI 1.4-11.4), body temperature (OR 1.7 for an increase by 1°C, 95%CI 1.02-2.68), and pleuritic pain (OR 2.8, 95%CI 1.1-7.6). Dyspnea (OR 0.3, 95%CI 0.1-0.7) and wheezing (OR 0.3, 95%CI 0.13-0.95) were inversely associated with antibiotic prescribing. CONCLUSION Laboratory markers were strong drivers of antibiotic prescribing in children with febrile lower respiratory tract infections, in spite of their known poor prediction of antibiotic need. Building on current guidelines for antibiotic treatment in children with febrile LRTI, a reliable decision algorithm for safe antibiotic withholding considering the laboratory and clinical factors evaluated in this study has the potential to further reduce antibiotic prescribing.

Abstract
PURPOSE OF REVIEW Wheezing in infancy is a common presentation with many potential causes. In writing this review, we sought to summarize the newest recommendations and testing available for the more common etiologies of wheezing. RECENT FINDINGS Regarding the diagnosis of asthma, the modified asthma predictive index has recently been established as a useful predictive tool. Non-breath held multidetector CT with 3D volume rendering airway images is also a newer helpful diagnostic tool for tracheomalacia due to ease of use and its 100% positive predictive value. We found vaccines have greatly reduced the prevalence of epiglottitis, while advances in surgery are improving outcomes in infants with vascular rings. Wheezing in infants is a common problem with an extensive differential diagnosis from relatively benign to life threatening. To prevent over-looking a diagnosis that potentially requires surgical correction or emergent care, we recommend a structured approach to the history and physical exam with targeted testing directed towards the most likely diagnoses as outlined in this review.

Abstract
OBJECTIVES The diagnosis of pediatric community-acquired pneumonia (CAP) is based on clinical criteria. Even though chest x-ray (CXR) is only recommended in severe cases, it is often requested from physicians in mild cases, thus increasing radiation exposure. Lung ultrasound (LUS) is not included in the diagnostic workup. The objective of this study was to evaluate the diagnostic performance of LUS against CXR. METHODS Children who presented to the emergency department with clinical signs suggesting CAP and had already been evaluated with a CXR were included in the study. Availability of a pediatric sonographer expert in LUS was also considered a criterion for participation. Chest x-ray and LUS were considered positive for CAP in cases of alveolar or interstitial pattern of disease. The diagnostic criterion standard was the ex post diagnosis of pneumonia, made by an independent senior expert pediatrician, after evaluation of the complete medical chart. RESULTS Sixty-nine children were enrolled in the study, with 66 of 69 positive for CAP. Receiver operating characteristic curve analysis results for CXR were 95.5% sensitivity and 100% specificity, whereas for LUS, sensitivity was reported 92.42% and specificity 100%. Comparison of the 2 receiver operating characteristic curves revealed no difference in the diagnostic value of the 2 methods for the diagnosis of pneumonia (P = 0.658). However, LUS classified more cases as alveolar disease compared with CXR. CONCLUSIONS Lung ultrasound plays a significant role in the detection of CAP, not inferior to CXR. The aim of this study was to encourage the use of ultrasound as a first-line examination for CAP in children.

Abstract
Mortality and morbidity remain high in pediatric lower respiratory tract infections (LRTIs) despite progress in research and implementation of global diagnostic and treatment strategies in the last decade. Still, 120 million annual episodes of pneumonia affect children younger than 5 years each year leading to 1.3 million fatalities with the major burden of disease carried by low- and middle-income countries (95%). The definition of pneumonia is still challenging. Traditional diagnostic measures (i.e., chest radiographs, C-reactive protein) are unable to distinguish viral and from bacterial etiology. As a result, common antibiotic overuse contributes to growing antibiotic resistance. We present an overview of current evidence from observational and randomized controlled trials on a procalcitonin (PCT)-based diagnosis of pediatric LRTIs and discuss the need for an adequate PCT threshold for antibiotic treatment decision-making.

Abstract
OBJECTIVE The objective of this study was to evaluate the performance of ultrasound in detecting lung consolidation in children suspected of pneumonia, in comparison to the current gold standard, chest X-rays. MATERIALS AND METHODS From September 2013 to June 2014, a monocentric prospective study was performed on all children between 0 and 16 years-old, referred for chest X-ray for suspected pneumonia. Each child was examined by chest ultrasound by an examiner blinded to the chest X-ray. The presence or absence of areas of consolidation, their number and location were noted for each technique. The size of the consolidations identified only on ultrasound was compared with that of consolidations visible on both techniques. RESULTS 143 children (mean age 3 years; limits between 8days and 14 years) were included. Ultrasound detected at least one area of consolidation in 44 out of 45 patients with positive X-rays. Of the 59 areas of consolidation on X-ray, ultrasound identified 54. In the 8 patients with negative X-ray, ultrasound revealed 17 areas of consolidation. The mean size of consolidations visible only on ultrasound was 9.4mm; for consolidations visible on both techniques the mean size was 26mm (p<0.0001). The sensitivity and specificity of ultrasound were calculated at 98% and 92%. PPV and NPV were 85% and 99%, respectively. CONCLUSION Chest ultrasound is a fast, non-ionizing and feasible technique. With its high negative predictive value, it can replace X-rays in order to exclude lung consolidation in children, thus reducing radiation exposure in this population.

Predictive Accuracy of Chest Radiographs in Diagnosing Tachypneic Children. Indian J Pediatr 2016; 83:930-6. [PMID: 26935199 DOI: 10.1007/s12098-016-2057-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2015] [Accepted: 01/28/2016] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To test the predictive accuracy and reporting reproducibility of digital chest radiographs under low-resource conditions. METHODS One hundred thirty four tachypneic children who presented to two Indian hospitals were enrolled. Based on review of 16 variables recorded in the Emergency Room (ER) by a senior pediatrician, children were given one of the four clinical diagnoses: pneumonia, wheezy disease, mixed and non-respiratory. Every child also had a digital CXR. It was interpreted by ER physician, pediatrician and two independent radiologists. All used the same standardized interpretation system (one or more of: normal, minor patches, major patches, hyperinflation, lobar change, pleural effusion). RESULTS The 10 % of CXRs showing pleural effusions reliably predicted pneumonia and disease severity. For all other CXR findings, the correlation between CXR interpretation and clinical diagnosis was moderate to poor. Apart from pleural effusions, inter-observer agreements between interpretations made by ER physician, pediatrician and radiologist were also poor (kappa <0.4). CONCLUSIONS With the exception of pleural effusions, CXR findings, interpreted by a radiologist, had moderate to poor power to predict respiratory diagnosis or disease severity defined by a pediatrician. Value of CXRs was further reduced by poor inter-observer agreement. When investigating tachypneic children under low-resource conditions, CXRs should be used with a clear understanding of their limitations.

Abstract
INTRODUCTION Pneumonia is common presentation in the emergency room and is still a cause of morbidity and mortality. The rationale of this study was to test the trend of paediatricians to achieve rapid response facing severe pneumonia, the lack of agreed on plan for the management of community acquired pneumonia (CAP) and the few experiences regarding injectable form of β-lactam antimicrobial. MATERIALS AND METHODS This is a prospective case control study, purposive randomized sampling, three patients were excluded since their information was incomplete, 132 patients were randomly divided into groups, one group named control group (penicillin according to the guidelines of WHO 2013), 33 patients; second group treated by β-lactam inhibitors (Augmentin IV) 50 patients; and third group treated by 3(rd) generation cephalosporin (ceftriaxone) 49 patients. The study was conducted at the main tertiary care and paediatrics teaching hospital in Khartoum capital of Sudan. The study was completed within the duration from 2010 to 2011. RESULTS Both group showed more or less similar results regarding response, as well as the failure rate however, the Augmentin and ceftriaxone groups showed a little bit better survival than the control group. CONCLUSION Antibiotics decrease the mortality rate among the pneumonia patients provided that it is given early in the disease.

Abstract
RATIONALE Plasma-detectable biomarkers that rapidly and accurately diagnose bacterial infections in children with suspected pneumonia could reduce the morbidity of respiratory disease and decrease the unnecessary use of antibiotic therapy. OBJECTIVES Using 56 markers measured in a multiplexed immunoassay, we sought to identify proteins and protein combinations that could discriminate bacterial from viral or malarial diagnoses. METHODS We selected 80 patients with clinically diagnosed pneumonia (as defined by the World Health Organization) who also met criteria for bacterial, viral, or malarial infection based on clinical, radiographic, and laboratory results. Ten healthy community control subjects were enrolled to assess marker reliability. Patients were subdivided into two sets: one for identifying potential markers and another for validating them. MEASUREMENTS AND MAIN RESULTS Three proteins (haptoglobin, tumor necrosis factor receptor 2 or IL-10, and tissue inhibitor of metalloproteinases 1) were identified that, when combined through a classification tree signature, accurately classified patients into bacterial, malarial, and viral etiologies and misclassified only one patient with bacterial pneumonia from the validation set. The overall sensitivity and specificity of this signature for the bacterial diagnosis were 96 and 86%, respectively. Alternative combinations of markers with comparable accuracy were selected by support vector machine and regression models and included haptoglobin, IL-10, and creatine kinase-MB. CONCLUSIONS Combinations of plasma proteins accurately identified children with a respiratory syndrome who were likely to have bacterial infections and who would benefit from antibiotic therapy. When used in conjunction with malaria diagnostic tests, they may improve diagnostic specificity and simplify treatment decisions for clinicians.

Ultrasound detection of pneumonia in febrile children with respiratory distress: a prospective study. Eur J Pediatr 2016; 175:163-70. [PMID: 26283293 DOI: 10.1007/s00431-015-2611-8] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2014] [Revised: 07/20/2015] [Accepted: 07/30/2015] [Indexed: 12/26/2022]
Abstract
UNLABELLED To analyse the usefulness of bedside lung ultrasound (LUS) in detecting lung consolidation in a paediatric emergency room (ER) setting, febrile children seen at our ER from 2008 to 2012 with a moderate to severe respiratory distress underwent LUS, chest X-ray (CXR) and laboratory investigations. At first ER assessment, LUS identified a lung consolidation in 207 patients of 222 children enrolled, with a liver-like appearance in 75 (36.2%) and an associated pleural effusion in 36.7% of cases. CXR proved positive in 197 cases, showing a parenchymal consolidation (68.5%) or a focal ground-glass opacity (31.4%). LUS liver-like consolidation was significantly associated with longer duration of fever (p = 0.002), higher neutrophil counts and C-reactive protein (CRP) values (p = 0.015 and p < 0.0001, respectively), and with the discovery of a homogeneous and dense parenchymal consolidation on CXR (p < 0.0001). CONCLUSION LUS can be adopted by the clinician as a non-invasive bedside tool to expand the physical evaluation of febrile children with respiratory distress. In our study, LUS results appeared not only as reliable as CXR in detecting lung consolidations but also consistent with clinical and laboratory data. WHAT IS KNOWN The diagnosis of pneumonia is mainly based on physical examination plus radiologic and laboratory evaluation when needed. Although lung ultrasound (LUS) has shown high sensitivity in detecting several pleuropulmonary diseases in adults, its role in the work-up of pneumonia in children is not yet widely recognized. WHAT IS NEW LUS is confirmed to be a reliable imaging technique for the diagnostic work-up of febrile children with respiratory distress, consistent not only with CXR results as previously reported by others but also with clinical and laboratory data. In the hands of trained clinicians, it may represent a valuable supplemental bedside tool for a rapid evaluation in such circumstances.

Abstract
OBJECTIVE The role of lung ultrasound (LUS) integrated with chest X-ray (CXR) for the first-line diagnosis of paediatric pneumonia; to define its role during the follow-up to exclude complications. METHODS We performed a retrospective review of a cohort including 84 consecutive children (age range: 3-16 years; mean age: 6 years; 44 males, 40 females) with clinical signs of cough and fever. All the patients underwent CXR at admission integrated with LUS. Those positive at LUS were followed up with LUS until the complete resolution of the disease. RESULTS CXR showed 47/84 pneumonic findings. LUS showed 60/84 pneumonic findings; 34/60 pneumonic findings had a typical pattern of lung consolidation; 26/60 pneumonic findings showed association of multiple B-lines, findings consistent with interstitial involvement, and small and hidden consolidations not achievable by CXR. One case was negative at LUS because of retroscapular location. 60 patients were followed up with LUS; 28/60 patients showed a complete regression of the disease; 23/60 patients had a significant decrease in size of consolidation; 9/60 patients showed disease stability or insignificant decrease in size, thus requiring adjunctive LUS examinations. CONCLUSION LUS, integrated with CXR, revealed to be an accurate first-line technique to identify small pneumonic consolidations, especially for "CXR-occult" findings, and for early diagnosis of pleural effusion; furthermore, LUS follow-up allows complications to be verified and additional radiation exposures to be avoided. ADVANCES IN KNOWLEDGE The effective role of LUS in the diagnosis and follow-up of lung consolidations and pleural effusions in paediatric patients in an emergency setting.

Abstract
OBJECTIVE To compare the outcome of treatment with narrow spectrum versus broad spectrum antibiotics in children hospitalized with community-acquired pneumonia (CAP) who received oral antibiotic treatment prior to their hospitalization. DESIGN, SETTING, AND PATIENTS A review of all previously healthy children from 3 months to 18 years with non-complicated CAP who received an oral antibiotic course in the community and were admitted from 2003 to 2008 to our pediatric departments. MAIN OUTCOME MEASURES Clinical course and outcome parameters were compared for treatment with narrow and broad spectrum antibiotics. RESULTS Of the 337 children admitted with non-complicated CAP after an oral antibiotic treatment course in the community, 235 were treated with broad spectrum, and 102 with narrow spectrum antibiotics. The two groups were similar regarding age, sex, days of fever prior to admission, type of preadmission oral antibiotic treatment, and laboratory indices at admission (P > 0.1). The broad spectrum-treated group had significantly better outcomes in terms of number of febrile days (1.2 ± 1.1 vs. 1.7 ± 1.6, P < 0.001), number of days treated with intravenous antibiotics (3.1 ± 1.3 vs. 3.9 ± 2.0, P < 0.001), and days of hospitalization (3.5 ± 1.5 vs. 4.2 ± 2.0, P < 0.001). The odds ratio for remaining hospitalized at 72 hr and 7 days was significantly higher for the narrow spectrum group (2.0 and 5.5 respectively, P < 0.05). CONCLUSIONS In previously healthy children hospitalized with CAP after oral antibiotic treatment in the community treatment with broad spectrum antibiotics showed better outcome. Prospective studies are needed for appropriate recommendation.

Agreement Between the World Health Organization Algorithm and Lung Consolidation Identified Using Point-of-Care Ultrasound for the Diagnosis of Childhood Pneumonia by General Practitioners. Lung 2015; 193:531-8.

Abstract
PURPOSE The World Health Organization (WHO) case management algorithm for acute lower respiratory infections has moderate sensitivity and poor specificity for the diagnosis of pneumonia. We sought to determine the feasibility of using point-of-care ultrasound in resource-limited settings to identify pneumonia by general health practitioners and to determine agreement between the WHO algorithm and lung consolidations identified by point-of-care ultrasound. METHODS An expert radiologist taught two general practitioners how to perform point-of-care ultrasound over a seven-day period. We then conducted a prospective study of children aged 2 months to 3 years in Peru and Nepal with and without respiratory symptoms, which were evaluated by point-of-care ultrasound to identify lung consolidation. RESULTS We enrolled 378 children: 127 were controls without respiratory symptoms, 82 had respiratory symptoms without clinical pneumonia, and 169 had clinical pneumonia by WHO criteria. Point-of-care ultrasound was performed in the community (n = 180), in outpatient offices (n = 95), in hospital wards (n = 19), and in Emergency Departments (n = 84). Average time to perform point-of-care ultrasound was 6.4 ± 2.2 min. Inter-observer agreement for point-of-care ultrasound interpretation between general practitioners was high (κ = 0.79, 95 % CI 0.73-0.81). The diagnosis of pneumonia using the WHO algorithm yielded a sensitivity of 69.6 % (95 % CI 55.7-80.8 %), specificity of 59.6 % (95 % CI 54.0-65.0 %), and positive and negative likelihood ratios of 1.73 (95 % CI 1.39-2.15) and 0.51 (95 % CI 0.30-0.76) when lung consolidation on point-of-care ultrasound was used as the reference. CONCLUSIONS The WHO algorithm disagreed with point-of-care ultrasound findings in more than one-third of children and had an overall low performance when compared with point-of-care ultrasound to identify lung consolidation. A paired approach with point-of-care ultrasound may improve case management in resource-limited settings.

Abstract
BACKGROUND Mycoplasma pneumoniae is a common cause of community-acquired pneumonia (CAP) in children. The aim of this study was to assess the prevalence of Mycoplasma pneumoniae infection in children with CAP and find clinical, radiological and laboratory features helpful to diagnose Mycoplasma pneumoniae pneumonia. Furthermore, we evaluated the value of serology, real-time PCR (RT-PCR) and culture for the accurate diagnosis of Mycoplasma pneumoniae pneumonia. METHODS The study included 166 children aged between 1 and 15 years with radiologically confirmed pneumonia. Throat swab specimens were cultured and assessed by RT-PCR for the presence of Mycoplasma pneumoniae. Mycoplasma pneumoniae-specific IgM and IgG antibodies were determined using ELISA in paired sera. RESULTS Mycoplasma pneumoniae pneumonia was diagnosed in 14.5% CAP cases. Cough (p=0.029), headache (p=0.001) and wheezing (p=0.036) were more frequent in children with Mycoplasma pneumoniae pneumonia compared to children with pneumonia caused by other pathogens. Logistic regression analysis showed that headache (odds ratio [OR] =36.077, p=0.001) and wheezing (OR=5.681, p=0.003) were significantly associated with MP pneumonia. Neither radiological findings, nor common laboratory parameters distinguished Mycoplasma pneumoniae infection in children with CAP. Using IgG serology in paired sera as the gold standard, we found that sensitivity of IgM serology, RT-PCR and culture was equal (81.82%), while specificity values were 100%, 98.6% and 100% respectively. We observed that combination of IgM detection in acute-phase serum and RT-PCR was positive for 91.7% of cases with Mycoplasma pneumoniae infection. CONCLUSIONS There are no characteristic radiological findings, or routine laboratory tests that would distinguish CAP caused by Mycoplasma pneumoniae from other CAP. It was found that clinical features such as headache and wheezing are indicative for Mycoplasma pneumoniae infection. Furthermore, it was found that during the acute phase of disease, detection of IgM antibodies in combination with RT-PCR allows for precise and reliable diagnosis of Mycoplasma pneumoniae infections in children.

Abstract
We assessed the diagnostic accuracy of digital photographs of plain film chest X-rays (CXRs) obtained using a mobile phone. The study was a randomized, non-inferiority trial, in which physical plain film CXRs viewed on a light box were compared with digital photographs of plain film CXRs. CXRs were selected from a database of radiology studies to show common pathologies found in Botswana associated with pneumonia, lung carcinoma, tuberculosis, pneumothorax and interstitial disease, as well as normal findings. The pre-selected diagnoses were subsequently verified by a second radiologist. Seven radiologists were randomized to review 75 plain film CXRs on light boxes before viewing 75 digital photographs, or vice versa. Their responses were considered correct if they matched the pre-defined diagnosis. For both modalities, the correct diagnosis was provided in 79% of cases; for plain film CXRs, the correct diagnosis was provided in 82% of cases and for digital photographs the correct diagnosis was provided in 76% of cases. The difference in diagnostic accuracy was -5.7% (95% CI: -10.8% to -0.5%), which confirmed non-inferiority (P<0.001) for the primary outcome of diagnostic accuracy. A subgroup analysis demonstrated non-inferiority for lung carcinoma and pneumonia images, although non-inferiority was not achieved for pneumothorax, tuberculosis, interstitial disease or normal images. The study demonstrates that digital photographs of CXRs obtained via a mobile phone equipped with a digital camera are non-inferior to plain film CXRs.

Abstract
BACKGROUND Lung ultrasound is a non-radiating accurate alternative tool to chest X-ray (CXR) in the diagnosis of community-acquired pneumonia (CAP) in adults. OBJECTIVES The aim of our study was to define the accuracy of ultrasound in the diagnosis of CAP in children. METHODS 107 consecutive children with suspected CAP underwent clinical examination, blood sample analysis, CXR and lung ultrasound on admission to the Pediatric Department of the San Paolo Hospital. The diagnosis of pneumonia was made by an independent committee of physicians on the basis of the overall clinical and CXR data. RESULTS The diagnosis of CAP was confirmed by the committee in 81 patients (76%). Ultrasound and CXR were performed in all patients. Ultrasound had a sensitivity of 94% and specificity of 96%, while CXR showed a sensitivity of 82% and a specificity of 94%. In patients with CAP, ultrasound revealed subpleural consolidations with air bronchogram in 70 cases and focal B-lines in 6. A parapneumonic pleural effusion was detected in 17 patients by ultrasound, while only 11 of them could be detected by CXR. CONCLUSIONS In our series, lung ultrasound was highly accurate for the diagnosis of CAP in hospitalized children. These results provide the rationale for a multicenter study in children.

Abstract
PURPOSE Abdominal radiographs are frequently employed in the surveillance of patients with necrotizing enterocolitis (NEC), with typical findings well described. Clinicians interpret and act upon these films at different intervals, however, and inter-rater agreement has not been evaluated to date. METHODS Thirty abdominal radiographs of premature infants were distributed to attending radiologists (4), pediatric surgeons (4), and trainees (4), who evaluated for findings of NEC from a list of eight potential choices (1=normal, 8=perforation). Fleiss's Kappa (FK) was used to evaluate concordance between multiple raters with 0-0.2=slight association and 0.8-1=almost perfect agreement. RESULTS Practicing surgeons had an FK of 0.77 overall (95% CI: 0.67-0.87), but demonstrated poor agreement when evaluating decubitus films (FK: 0.39, 95% CI:0.12-0.65). Radiologists had excellent inter-rater agreement (FK: 0.81, 95% CI: 0.74-0.88), but had only modest agreement with surgeons (FK: 0.59, 95% CI: 0.56-0.63) and poor agreement for decubitus films (FK: 0.15, 95% CI: 0.47-0.26). Surgical and radiology trainees had fair agreement with their respective attendings (0.60, 95% CI: 0.55-0.65 and 0.64, 95% CI: 0.60-0.69, respectively). CONCLUSIONS While inter-rater agreement was good-excellent among attending staff, it was only moderate between radiologists and surgeons and between trainees and their attendings. This highlights the importance of inter-disciplinary and hierarchical communication to optimize clinical decision-making. Decubitus films may be of limited value in evaluating patients with NEC.

Performance of lung ultrasonography in children with community-acquired pneumonia. Ital J Pediatr 2014; 40:37. [PMID: 24742171 PMCID: PMC4012508 DOI: 10.1186/1824-7288-40-37] [Citation(s) in RCA: 68] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2013] [Accepted: 04/14/2014] [Indexed: 11/26/2022] Open
Abstract
Background There are few prospective evaluations of point-of-care ultrasonography (US) for the diagnosis of pediatric community-acquired pneumonia (CAP). In particular, there are very few data concerning the efficiency of US in comparison with that of chest radiography (CR) in defining different kinds of lung alterations in the various pulmonary sections. The aim of this study was to bridge this gap in order to increase our knowledge of the performance of US in diagnosing CAP in childhood. Methods A total of 103 children (56 males, 54.4%; mean age ± standard deviation 5.6 ± 4.6 years) admitted to hospital with a clinical diagnosis of suspected CAP were prospectively enrolled and underwent CR (evaluated by an independent expert radiologist) and lung US (performed by a resident in paediatrics with limited experience in US). The performance of US in diagnosing CAP (i.e. its sensitivity, specificity, and positive and negative predictive values) was compared with that of CR. Results A total of 48 patients had radiographically confirmed CAP. The sensitivity, specificity, and positive and negative predictive values of US in comparison with CR were respectively 97.9%, 94.5%, 94.0% and 98.1%. US identified a significantly higher number of cases of pleural effusion, but the concordance of the two methods in identifying the type of CAP was poor. Conclusion US can be considered a useful means of diagnosing CAP in children admitted to an Emergency Department with a lower respiratory tract infection, although its usefulness in identifying the type of lung involvement requires further evaluation.

Abstract
BACKGROUND Consolidation on chest radiography is widely used as the reference standard for defining pneumonia and variability in interpretation is well known but not well explored or explained. METHODS Three pediatric sub-specialists (infectious diseases, radiology and respiratory medicine) viewed 3,033 chest radiographs in children aged under 5 years of age who presented to one Emergency Department (ED) with a febrile illness. Radiographs were viewed blind to clinical information about the child and blind to findings of other readers. Each chest radiograph was identified as positive or negative for consolidation. Percentage agreement and kappa scores were calculated for pairs of readers. Prevalence of consolidation and reader sensitivity/specificity was estimated using latent class analysis. RESULTS Using the majority rule, 456 (15%) chest radiographs were positive for consolidation while the latent class estimate was 17%. The radiologist was most likely (21.3%) and respiratory physician least likely (13.7%) to diagnose consolidation. Overall percentage agreement for pairs of readers was 85-90%. However, chance corrected agreement between the readers was moderate, with kappa scores 0.4-0.6 and did not vary with patient characteristics (age, gender, and presence of chronic illness). Estimated sensitivity ranged from 0.71 to 0.81 across readers, and specificity 0.91 to 0.98. CONCLUSIONS Overall agreement for identification of consolidation on chest radiographs was good, but agreement adjusted for chance was only moderate and did not vary with patient characteristics. Clinicians need to be aware that chest radiography is an imperfect test for diagnosing pneumonia and has considerable variability in its interpretation.

Abstract
An increasingly amount of evidence suggests that lung ultrasonography constitutes a relevant complementary diagnostic tool for adults patient in acute respiratory failure. A comprehensive and standardized ultrasonographic semiology has been described, relying on accurate and reproducible data directly obtained at patient's bedside. Therefore, pleural effusion, pneumothorax, pulmonary consolidation and interstitial lung disease can be diagnosed in a critical care environment with a similar level of performance than when reference diagnosis methods such as thoracic CT-scan are employed. Furthermore, lung ultrasonography seems to be able to contribute to an early therapeutic decision based on such online physiopathological data. Pioneers works in this field have suggested an attractive similarity between the ultrasonographic patterns described in adults and children. Nevertheless, the clinical usefulness of lung ultrasonographic approach in the pediatric critical care medicine still needs to be confirmed by specifically designed studies.
