Spontaneous renal artery dissection diagnosed by unenhanced magnetic resonance angiography: case report
Full text linkA 47-year-old patient is presented who was admitted to the emergency department with complaints of right-sided flank pain and hypertension. His creatinine and glomerular filtration rate were 2.5 mg/dl and 37 ml/min respectively, so that contrast media administration was contraindicated. The unenhanced magnetic resonance angiography image obtained with 3D in-flow inversion recovery sequence showed right renal artery dissection, without aortic dissection. Selective renal angiography confirmed the diagnosis and a stent was placed in the renal artery. The patient was free of pain after stenting, with normalized laboratory values and blood pressure.

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
Comparison between echocolordoppler and angio-magnetic-resonance imaging in the diagnosis of renal artery stenosis
No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Favourable outcome without need for haemodialysis in a pregnant patient with severe chronic renal failure
No full textA case of favorable outcome of pregnancy without haemodialysis in a young woman with advanced chronic renal failure is described. Issues related to beginnig and timing of dialysis in these patients are discussed, in view of the controversial reports existing in the literature concerning pregnancy in patients with chronic glomerular disease and renal insufficiency. Our observation suggests the possibility of delaying dialysis treatment in pregnant patients lacking uremic symptoms
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
