[Show abstract][Hide abstract] ABSTRACT: Malperfusion of the thoracoabdominal aorta and its side branches is a common complication of aortic dissection, often proving fatal. Vital organ malperfusion accompanying acute aortic dissection is a major cause of mortality and morbidity and requires timely reperfusion of the ischemic organs as well as adequate management of the aortic dissection. Ischemic damage to vital organs supplied by the thoracoabdominal aorta greatly increases the overall risk of aortic dissection. As initial symptoms may be subtle, malperfusion tends to be recognized late, and therefore accounts for a considerable percentage of fatalities.Effective reperfusion is not readily achieved by central aortic surgery alone in a certain number of patients. Various strategies have been used, including entry closure by central aortic surgery or stent grafting, surgical or catheter fenestration, bypass grafting and percutaneous stenting.Endovascular bare-metal stent placement is an attractive and promising treatment option since it is readily available, is less invasive and presents fewer risks to the patient.
[Show abstract][Hide abstract] ABSTRACT: The development of a noninvasive diagnostic test follows a typical timeline: description, enthusiasm, clinical assessment and application, and epidemiological study. However, for techniques such as echocardiography that are widely available, have no harmful effects and are inexpensive, clinical applications may become widespread before they have been evaluated. Real progress is being made with the use of new methodologies, such as myocardial deformation echocardiography and three-dimensional echocardiography. Three-dimensional transesophageal echocardiography has returned echocardiography
to its place at the center of modern cardiac diagnosis after it had been displaced in recent years by cardiac multislice CT and cardiac magnetic resonance. However, the new radiological techniques that have helped to reduce radiation exposure to patients and that have improved image acquisition could restore CT to the heart of general cardiac diagnosis. At the moment, it is not possible to displace the echocardiography from
its central role in cardiac imaging. This article contains a review of the most important publications on echocardiography, magnetic resonance imaging and cardiac CT that have appeared recently in cardiology journals, mainly during 2010.

[Show abstract][Hide abstract] ABSTRACT: Our paper, which is a part of a larger research project, presents the effects that the teaching-learning process based on electronic models has on Romanian primary school students as compared to the traditional one. The basis of our research is an investigation sample made up of 158 pupils. Our comments upon this issue respond to the following questions: how can technology improve maths’ learning process? on what grounds? What are the modern models that should be implemented in Romanian primary schools? what are the specific effects these models have on students, how are they perceived by the representatives of the British School, of the French School?
