INTRODUCTION: In the prehospital setting, Emergency Medical Services (EMS) professionals rely on providing positive pressure ventilation with a bag-valve-mask (BVM). Multiple emergency medicine and critical care studies have shown that lung-protective ventilation protocols reduce morbidity and mortality. Our primary objective was to determine if a group of EMS professionals could provide ventilations with a smaller BVM that would be sufficient to ventilate patients. Secondary objectives included 1) if the pediatric bag provided volumes similar to lung-protective ventilation in the hospital setting and 2) compare volumes provided to the patient depending on the type of airway (mask, King tube, and intubation)...

Predicting noise properties of iteratively reconstructed CT images is useful for analyzing reconstruction methods; for example, local noise power spectrum (NPS) predictions may be used to quantify the detectability of an image feature, to design regularization methods, or to determine dynamic tube current adjustment during a CT scan. This paper presents a method for fast prediction of reconstructed image variance and local NPS for statistical reconstruction methods using quadratic or locally quadratic regularization...

Spontaneous Bacterial Empyema (SBEM) denotes infection of the pleural fluid in the absence of pneumonia. Almost all cases of SBEM in literature are described in a background of ascites secondary to cirrhosis. Contiguous spread of the infected ascitic fluid through defects in the diaphragm is the most likely mechanism of SBEM. Most of these cases are transudative in nature and are managed with antibiotics. Literature on SBEM in the absence of cirrhosis or ascites is very limited so far. We describe a 59 year old female with ESRD status post renal transplant, on chronic immunosuppression for renal allograft rejection who was admitted with pleuritic chest pain that turned to be secondary to right sided pleural effusion...

PURPOSE: To develop a method for estimating doses to primarily exposed organs in pediatric CT by taking into account patient size and automatic tube current modulation (ATCM). METHODS: A Monte Carlo CT dosimetry software package, which creates patient-specific voxelized phantoms, accurately simulates CT exposures, and generates dose images depicting the energy imparted on the exposed volume, was used. Routine head, thorax, and abdomen/pelvis CT examinations in 92 pediatric patients, ranging from 1-month to 14-yr-old (49 boys and 43 girls), were simulated on a 64-slice CT scanner...

OBJECTIVE AND IMPORTANCE: Infective endocarditis involving the tricuspid valve is an uncommon condition, and a consequent haemothorax associated with pulmonary embolism is extremely rare. Particularly, there are no guidelines for the management of this complication. We describe a rare case of pulmonary embolism and infarction followed by a haemothorax due to infective endocarditis of the tricuspid valve caused by Streptococcus sanguinis. CLINICAL PRESENTATION: A 25-year-old man with a ventricular septal defect (VSD) presented with fever...

Human bocavirus (HBoV), that was first identified in 2005 and classified in Parvoviridae family, is a small, non-enveloped, single-stranded DNA virus, responsible for upper and lower respiratory tract infections, especially in young children. Although HBoV generally causes self-limited influenza-like illness, it may also lead to pneumonia, bronchiolitis, croup and asthma attacks. In this report, a case of acute bronchiolitis complicated with pneumomediastinum and bilateral pneumothorax caused by HBoV has been presented...

BACKGROUND: Minimally invasive esophagectomy (MIE) has the potential to reduce the morbidity and mortality of esophageal cancer surgery. Esophageal squamous cell carcinoma (ESCC) has a high incidence of earlier lymphatic spread and is usually located more proximal to the incisor than esophageal adenocarcinoma; consequently, the anastomosis should be made more proximal in the thorax or in the neck. We adopted the proximal intrathoracic anastomotic technique using thoracoscopy for mid-to-lower ESCC...

Oesophageal rupture is a life-threatening complication of balloon tamponade for bleeding oesophageal varices. We herein describe the clinical course and imaging findings in a 33-year-old Indian man who had a Sengstaken-Blakemore (SB) tube inserted for uncontrolled haematemesis, which was unfortunately complicated by malposition of the gastric balloon with resultant oesophageal rupture. The inflated SB tube gastric balloon was visualised within the right hemithorax on chest radiography after the SB tube insertion...

INTRODUCTION/BACKGROUND: Occult pneumothorax (OPTX) is defined as air within the pleural cavity that is undetectable on normal chest X-rays, but identifiable on computed tomography. Currently, consensus is divided between tube thoracostomy and conservative management for OPTX. METHODS: The aim of this retrospective study is to determine whether OPTX can be managed conservatively and whether any adverse events occur under conservative management. Data on all trauma patients from 1 Jan 2010 to 31 December 2012 were obtained from our hospital's trauma registry...

The purpose of this study was to show that the nominal peak tube voltage potential (kVp) and measured half-value layer (HVL) can be used to generate energy spectra and fluence profiles for characterizing a computed tomography (CT) X-ray source, and to validate the source model and an in-house kV X-ray dose computation algorithm (kVDoseCalc) for computing machine- and patient-specific CT dose. Spatial variation of the X-ray source spectra of a Philips Brilliance and a GE Optima Big Bore CT scanner were found by measuring the HVL along the direction of the internal bow-tie filter axes...
