Life threatening event due to central airway obstruction caused by very large blood clot formation with profuse on going bleeding its very challenging to manage. Interventional pulmonologist must aware about this situation which can lead to respiratory failure. There are several choices to treat this unlikely situation, in example flexible bronchoscopy with forceps, bronchial lavage, and suctio...

The present study assesses the innovative concept of empathic accuracy within a crew-aircraft-system in a realistic approach scenario. Empathy, one of the key skills of social situation awareness (SSA), was found to be altered in stressful situations. Challenging and surprising events lead to a decrease in empathic accuracy in both pilot flying and pilot monitoring. Stress therefore significant...

How to secure outsourcing data in cloud computing is a challenging problem, since a cloud environment cannot been considered to be trusted. The situation becomes even more challenging when outsourced data sources in a cloud environment are managed by multiple outsourcers who hold different access rights. In this paper, we introduce an efficient and novel tree-based key management scheme that al...

Background Myocarditis presenting as isolated acute chest pain with elevated troponins but normal systolic function by echocardiogram is rare in previously healthy children. Diagnosis is challenging in this situation with significant drawbacks even for the gold standard endomyocardial biopsy. Our study aim is to evaluate the diagnostic role of cardiac MRI in comparison with echocardiography in ...

In this editions' 'Experts Opinion', the management of hy-potony and choroidal effusion following glaucoma filtration surgery is discussed. We are delighted to welcome Clinical Associate Professor Ivan Goldberg and Professor Franz Grehn and Paul Chew to the panel to provide opinion on this very challenging clinical situation.

This paper discusses the technical challenges in maritime image processing and machine vision problems for video streams generated by cameras. Even well documented problems of horizon detection and registration of frames in a video are very challenging in maritime scenarios. More advanced problems of background subtraction and object detection in video streams are very challenging. Challenges a...

Acute appendicitis is one of the frequently seen emergencies in the pediatric hospitals. Nevertheless, its diagnosis and management is often challenging in infants and neonates. The diagnosis is frequently made at operation performed for the complications [1-3]. We encountered a similar situation in a 2-month-old infant in whom the perforated appendicitis presented with small bowel obstruction.

Infectious lymph nodes mimicking lymphoma is challenging for accurate staging. Although 18F-FDG is a nonspecific tracer accumulating not only in tumor cells but also in inflammatory tissues, the metabolic features and uptake kinetics give valuable information: 18F-FDG PET/CT appears as a useful problem solver tool in ambiguous situation.
