GOAL: Chest auscultations offer a non-invasive and low-cost tool for monitoring lung disease. However, they present many shortcomings including inter-listener variability, subjectivity, and vulnerability to noise and distortions. The current work proposes a computer-aided approach to process lung signals acquired in the field under adverse noisy conditions, by improving the signal quality and offering automated iden- tification of abnormal auscultations indicative of respiratory pathologies...

Pediatric pneumonia can be complicated by necrotizing pneumonia or a parapneumonic effusion either in the form of an empyema or a clear effusion. Ultrasonography (US) and computed tomography represent well-established modalities for evaluation of complicated pediatric pneumonia. Contrast-enhanced ultrasound (CEUS) was recently introduced and is gaining increasing acceptance in pediatric imaging. In this case series, we present our initial experience with both intravenous and intracavitary use of CEUS in children with complicated pneumonia...

OBJECTIVES: Emergency physicians (EPs) interpret plain radiographs for management and disposition of patients. Radiologists subsequently conduct their own interpretations, which may differ. The purposes of this study were to review the rate and nature of discrepancies between radiographs interpreted by EPs and those of radiologists in the pediatric emergency department, and to determine their clinical significance. METHODS: We conducted a retrospective review of discrepant radiology reports from a single-site pediatric emergency department from October 2012 to December 2014...

Our objective was to determine the clinical value of obtaining a chest radiograph after removal of a chest tube. We conducted a retrospective chart review of pediatric general surgical patients with a chest tube in place after a thoracic procedure over a 3-year time period. Postremoval films were considered to be of value if they led to a change in clinical management. Of 468 patients who had a thoracic procedure, 281 patients had a chest tube and a postremoval film. In 263 patients (93.6%) there was no change in the postremoval film result compared with baseline...

REVIEW
Matthew A Zapala, Victor M Ho-Fung, Edward Y Lee
This article focuses on commonly encountered primary lung, airway, mediastinal, and chest wall neoplasms that occur in the pediatric population. Although primary pediatric thoracic neoplasms are rare, imaging is critical in their diagnostic work-up. An overview of the latest imaging techniques specific to evaluate these pediatric thoracic neoplasms is presented across the spectrum of modalities from radiography to PET/MR imaging. In addition, the characteristic imaging appearances of these pediatric primary thoracic neoplasms are discussed with an emphasis on what the radiologist needs to know in routine clinical practice...

Pulmonary embolism is a life-threatening and potentially lethal disease. Its incidence in children with sickle cell disease is probably underestimated and pediatric case reports in the literature are rare. Moreover, symptoms can mimic an acute chest syndrome. We report on the case of a 17-year-old boy with SS sickle cell disease, admitted for chest pain with dyspnea and tachycardia. Pulmonary angiography revealed a partial bilateral obstructive pulmonary embolism. We did not find any deep venous thrombosis or thrombophilia...

Hypercalcemia is a rare metabolic disorder associated with hyperparathyroidism, malignancy and various other causes. Although common in adult malignancies, hypercalcemia is rare in pediatrics and purports poor prognosis. Nasopharyngeal carcinoma is rare with no reported hypercalcemic presentation. We present here a case of hypercalcemia in a child of nasopharyngeal carcinoma. A 10 year girl presented with backache for 1 month, epistaxis, cough, chest-pain for 1 week alongwith anorexia and weight loss. Investigations revealed anemia and hypercalcemia (23mg/dl; normal range 9-11 mg/dl) with hyperphosphatemia, normal parathyroid levels...

Representation learning through deep learning (DL) architecture has shown tremendous potential for identification, localization, and texture classification in various medical imaging modalities. However, DL applications to segmentation of objects especially to deformable objects are rather limited and mostly restricted to pixel classification. In this work, we propose marginal shape deep learning (MaShDL), a framework that extends the application of DL to deformable shape segmentation by using deep classifiers to estimate the shape parameters...
