No full textLaparascopic adrenalectomy of an incidental lesion
No full textThe authors report a case of incidental lesion of right adrenal gland in a 56-years-old patient, followed for a liver disfunction. The lesion, with cystic and hemorrhagic histological characters, was treated with laparoscopic resection. The following case report covers the diagnostic procedures, laparoscopic technique, showing the advantages, and postoperative course in surrenal lesion without local infiltration
Laparoscopy in iatrogenic lesions of the colon during operative endoscopy
No full textColonscopy is a standard diagnostic and therapeutic procedure that has its own morbidity. Colonic perforation is the dangerous complication of this procedure. Successful management of perforation by conservative or surgical treatment remains controversial. We report two cases, recently observed, of patients with colonic perforation occurring during therapeutic colonscopy treated with minimally invasive technique
Intestinal occlusion secondary to Morgagni-Larrey's herniation in an adult. Case report and analysis of the literature.
No full textMorgagni-Larrey's hernias are congenital diaphragmatic hernias, rarely observed and generally identified accidentally due to the lack of symptoms. The authors report a case of intestinal occlusion secondary to Morgagni-Larrey herniation in an adult recently observed and underline the aetiopathogenic aspects, the diagnostic tools and the clinical pattern. They suggest to consider surgical repair as a choice of treatment, also for asymptomatic patients
Aorto-mesenteric compression syndrome. Description of clinical case and critical review of the literature
No full textAorto-mesenteric duodenal compression syndrome is a rare disease in which superior mesenteric artery causes a substenosis of the duodenum. Pathogenesis of this syndrome is due to congenital or acquired factors. Symptomatology is usually non specific and intermittent. Diagnosis is given by selective superior mesenteric artery angiography. Therapy is only surgery
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
Variations 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
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
