Computed tomography scan utilization in pediatric trauma: impact on length of stay and incidence of false positive findings - Edwards MJ, Jenkel T, Weller B, Weber A, Zhu K, Parikh R, Ata A, Danziger C.

INTRODUCTION: Computerized tomography (CT) scans are the mainstay of diagnostic imaging in blunt trauma. Particularly in pediatric trauma, utilization of CT scans has increased exponentially in recent years. Concerns regarding radiation exposure to this vu...

Authors: Vegas-Sánchez-Ferrero G, José Estépar RS Abstract Lung parenchyma destruction (emphysema) is a major factor in the description of Chronic Obstructive Pulmonary Disease (COPD) and its prognosis. It is defined as an abnormal enlargement of air spaces distal to the terminal bronchioles and the destruction of alveolar walls. In CT imaging, the presence of emphysema is observed by a local decrease of the lung density and the diagnose is usually set as more than 5% of the lung below -950 HU, the so-called emphysema density mask. There is still debate, however, about the definition of this pe...

ConclusionCombined laparoscopic pouch resizing and distalization are safe and can lead to adequate weight loss. This technique allows the combination of an added restriction and malabsorption to the previous RYGB and could lead to an improved weight loss.

ConclusionWe present a new workflow that combines current known methods of both rapidly scanning a patient ’s surface and the subsequent rapid creation of bolus that then increases bolus conformity, improves comfort and the patient experience, reduces simulation time, and may decrease exposure to radiation.

A SR-NET 3D-TO-2D ARCHITECTURE FOR PARASEPTAL EMPHYSEMA SEGMENTATION. Proc IEEE Int Symp Biomed Imaging. 2019 Apr;2019:303-306 Authors: Bermejo-Peláez D, Okajima Y, Washko GR, Ledesma-Carbayo MJ, San José Estépar R Abstract Paraseptal emphysema (PSE) is a relatively unexplored emphysema subtype that is usually asymptomatic, but recently associated with interstitial lung abnormalities which are related with clinical outcomes, including mortality. Previous local-based methods for emphysema subtype quantification do not properly characterize PSE. This is in part for their inability to...

BACKGROUND Patients with blunt cerebrovascular injuries are at risk of thromboembolic stroke. Although primary prevention with antithrombotic therapy is widely used in this setting, its effectiveness is not well defined and requires further investigation. The aim of this study was to evaluate the utility of magnetic resonance imaging (MRI)–detected ischemic brain lesions as a possible future outcome for randomized clinical trials in this patient population. METHODS This prospective observational study included 20 adult blunt trauma patients admitted to a level I trauma center with a screening neck CTA showing ex...

CONCLUSION The AAST grading of acute diverticulitis is equivalent to the modified Hinchey classification in predicting procedural intervention and complications. The AAST system may be preferable to Hinchey because it can be applied preoperatively. Although this pilot study demonstrated that the AAST score predicts surgical need, a larger study is required to evaluate the AAST score for other outcomes. LEVEL OF EVIDENCE Prognostic and epidemiological study, level III.

Rationale: Primary malignant melanoma of the esophagus (PMME) is a very rare malignancy accounting for only 0.1% to 0.2% of all malignant esophageal lesions. Presently, there are no standard strategies or clear guidelines for PMME treatment. Patient concerns: Herein, we report a patient who had PMME with multiple lymph node metastases (LNMs) who was treated successfully by esophagectomy. In March 2018, a 74-year-old man with symptoms of continuous dysphagia was referred to our hospital. Diagnosis: Upper gastrointestinal endoscopic examination revealed melanin pigmentation in the middle thoracic esophagus and a pigm...
