Emoperitoneo da rottura di ematoma subcapsulare epatico indotto dal ketorolac dopo colecistectomia laparoscopica. Caso clinico
Get PDFIl ketorolac è uno dei più comuni antinfiammatori non steroidei usati per il dolore postoperatorio. Diversi studi hanno messo in evidenza come la somministrazione perioperatoria e postoperatoria del ketorolac
sia associata ad un aumentato rischio di sanguinamento. Questa evenienza, pur non essendo frequente, può esporre il paziente a gravi complicanze postoperatorie che devono essere conosciute per poter essere trattate tempestivamente ed efficacemente. Presentiamo il caso di una nostra paziente che, affetta da colelitiasi,è stata sottoposta a colecistectomia videolaparoscopica in elezione sviluppando,
nell’immediato postoperatorio, un’emorragia in un primo
momento attribuita all’atto chirurgico ed in seguito alla somministrazione di ketorolac
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
Basiliximab in a triple-drug regimen with tacrolimus and steroids in liver transplantation
No full textBackground. Basiliximab, a chimeric monoclonal antibody (mAb) directed against the α chain of the interleukin-2 (IL-2) receptor (CD25), has been extensively evaluated as induction therapy for kidney transplant recipients, more frequently in combination with a cyclosporine-based regimen. In this study, we assessed the efficacy and safety of basiliximab in combination with tacrolimus and steroids following liver transplantation. Methods. One hundred fifty-two liver transplant recipients (141 cadaveric donors and 11 living donors [LRLT]) in the last 4 years were treated with 2 20-mg doses of basiliximab (days 0 and 4 posttransplantation) followed by tacrolimus (0.15 mg/kg/d; 10-15 ng/mL target trough levels) and steroids (500 mg intravenous [IV] bolus at the reperfusion followed by 20 mg orally daily and weaning off in 1 or 2 months). Follow-up ranged from 104 to 1630 days after transplantation (mean, 665 days; SD ± 442.65; median, 509 days). Results. Eighty-five percent of patients remained rejection-free during follow-up with an actuarial rejection-free probability of 78% within 3 months. Nineteen patients had 22 episodes of biopsy-proven acute cellular rejection (ACR). Actuarial patient and graft survival rates at 3 years were 86.7% and 75.8%, respectively. Twenty-seven patients (20.6%) experienced 1 episode of sepsis, requiring temporary reduction of immunosuppressive therapy. There was no evidence of CMV infections or side effects related to basiliximab. We observed 2 de novo malignancies, 1 recurrence from an ileal carcinoid tumor and 1 pulmonary recurrence of hepatocellular carcinoma (HCC) in 1 recipient of LRLT. Conclusions. Basiliximab in association with tacrolimus and steroids is effective prophylaxis of ACR in liver transplant recipients and does not increase the incidence of infections or adverse effects. © 2005 by Elsevier Inc.

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
