Casual diagnosis of abdominal aorta aneurysm during transthoracic echocardiographic test: Clinical case and literature review
No full textAbdominal aorta aneurysm (AAA) is a silent pathology and, almost always, runs in a hidden way to the casual diagnosis or to the clinical manifestation of serious complications such as arterial rupture or peripheral embolization. It's therefore basic to use screening methods assuring high rate of preventive diagnosis. At the present time the most part of the abdominal aorta aneurysms is casually diagnosed during abdominal echography, only rarely for a specific clinical suspect. Rapidly evaluating the abdominal aorta (AA) diameters during the transthoracic echocardiographic test could represent, with a minimum increase of the test length, an efficacious screening of this disease. We are showing here a typical clinical case of casual diagnosis of AAA during an echocardiographic test on a patient with many risk factors. © 2005 Pharma Project Group srl
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
