Surgical Treatment of an Abdominal Abscess Caused by a Migrating Iron Wire From the Ventral Colon, a Case Report
No full textA 13-year-old mare presented for evaluation of recurrent colic episodes. The horse was
diagnosed with a mass within the spleen at the ultrasound examination of the abdomen;
the levels of Serum Amyloid A and the fibrinogen were high and so a presumptive diagnosis
of an abscess involving the spleen was made base on clinical, ultrasonographic and
laboratory findings and it was decided to perform n exploratory laparotomy for a definitive
diagnosis and possible treatment. Upon abdominal exploration a mass involving the
spleen, the lateral wall of the ventral colon adherent to the left abdominal wall was
diagnosed and with an intraoperative ultrasound examination a linear hyperechoic foreign
body was diagnosed within the mass. It was removed through an enterotomy of the left
ventral colon that allowed the digital exploration of the mass without spilling of pus
within the peritoneal cavity. The horse was discharged and the long term follow-up
revealed no complications and no more signs of abdominal pain

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
ERNIA DIAFRAMMATICA: RISOLUZIONE MEDIANTE TORACOSCOPIA IN STAZIONE CON UN MESH
No full textL’ernia diaframmatica è una patologia chirurgica poco frequente nel cavallo. Clinicamente
i cavalli che presentano questa patologia, si possono presentare con segni di dolore addominale
da lievi a gravi. La diagnosi si può ottenere con l’ecografia toracica, la radiografia del torace
o la laparatomia esplorativa. La riparazione chirurgica è stata descritta in anestesia generale mediante
celiotomia o laparotomia toraco-assistita e in stazione mediante toracoscopia e sutura dell’apertura
diaframmatica. Questo lavoro descrive la risoluzione chirurgica dell’ernia diaframmatica
utilizzando un particolare mesh in polopropilene, rivestito di un film idrofilico riassorbibile, inserito
nel paziente mediante intervento di toracoscopia in standing
Ultrasonographic findings of fluid accumulation and hyperechogenic spots suggestive of surgical site infection following laparotomy for colic in horses
No full textBackground: The aim of this study was to compare ultrasonographic findings of the ventral midline incision after exploratory laparotomy for colic in horses with and without surgical site infection (SSI). Methods: Ultrasonographic examination of the surgical wound was performed on postoperative day 5 (D5) and day 10 (D10) to assess the presence of fluid accumulation, suture sinus formation, hyperechogenic spots and fistulous path. Clinical evaluation of the wound was used to classify horses with and without SSI. The accuracy, sensitivity, specificity and positive and negative predictive values of the ultrasonographic findings were then calculated. Multivariable logistic regression analyses were performed with SSI as a dependent variable and age, sex, breed and ultrasonographic findings as independent variables after univariate and collinearity analyses. Results: Twenty-nine of the 84 horses examined had an SSI. Detection of fluid accumulation and hyperechogenic spots increased the odds for SSI at D5 (odds ratio [OR]: 4.99, 95% confidence interval [CI]: 1.53-16.33, p = 0.008; OR: 10.78, 95% CI: 1.75-26.59, p = 0.01, respectively) and D10 (OR: 11.51, 95% CI: 2.39-55.47, p = 0.002; OR: 12.34, 95% CI: 3.45-44.15, p < 0.001, respectively). Limitation: Ultrasonographic images were taken only on the longitudinal section. Conclusion: Ultrasonographic examination is helpful in evaluating the surgical incision after laparotomy, with the detection of fluid accumulation and hyperechogenic spots surrounding the sutures being strongly related to SSI
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
