Double traumatic diaphragmatic injury: A case report
No full textIntroduction: Traumatic diaphragmatic injuries are rare complications resulting from a thoracic-abdominal blunt or penetrating trauma. Left-sided diaphragmatic injuries are more commonly reported in literature. Bilateral injuries are extremely rare, occurring in about 3% of the patients and just few cases reported in literature. Traumatic diaphragmatic hernias are definitely a marker of a severe trauma, in fact diaphragmatic injuries are often related to thoracic and abdominal organs injuries. Sometimes the classic clinical signs and symptoms of diaphragmatic injuries may initially not be present so that definitive evaluation is delayed or even missed. Case report: A 62-years old woman was admitted in Emergency Department after a pedestrian accident. A whole-body CT scan showed multiple fractures (ribs, pelvic and vertebral) but no organ injury. The next CT detected a left-sided posterior diaphragmatic hernia involving transverse colon. Thus we performed an explorative laparoscopy and found a double diaphragmatic injury. A primary repair with non-absorbable sutures and a prosthetic titanized patch was performed
Tailored treatments in internal rectal prolapse
No full textBackground: Internal rectal prolapse is commonly reported in patients suffering pelvic floor disorders, such as obstructive defecation and incontince. Unfortunately, its treatment not always offers a symptoms resolution. Material and methods: To investigate the correct management and its influence in symptoms resolution, we investigated patients submitted to hierarchic therapeutic options from conservative to surgical treatments. An evaluation of the appropriate treatment tailored on the entity of the prolapse was proposed. Results: We investigated 84 patients [64 F, 20 M (median age 52)]. In 44 a symptoms resolution was obtained with medical therapy. To 40 patients biofeedback rehabilitation was offered and 18 of them improved. 22 were treated with a surgical approach that ranged from mucosal plication or mucopexy to transanal rectal resection according to the prolapse entity. Functional improvement was obtained in 21 patients regarding obstructive defecation syndrome while incontinence related symptoms were not statistically changed. We reported a serious complication in a patient treated with transanal rectal resection that suffered a fatal sepsis in the post-operative course. Discussion: The optimal management for internal rectal prolapse is still discussed. No one technique showed a superiority over the others. Pelvic floor retraining may be useful in patients with defecation disorders not associated with a high grade internal rectal prolapse. Mucosal plication can offer a safe role in the treatment of this anatomical disorder that is not always offers a symptoms resolution
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
