Su un caso autoptico di rottura splenica da mononucleosi infettiva. Valutazione del nesso di causalità materiale
No full textThe Authors describe a case of a 14-year-old, who died of a spontaneous rupture of
the spleen immediately after arriving at a First Aid Department. The diagnostic
examination revealed a hemoperitoneum and laceration of the spleen that, in view
of the young age of the victim, led the medical staff to request a postmortem. The
autopsy and subsequent serologic and histological tests allowed for the formulation
of an exact diagnosis of death. In fact, apart from the considerable splenomegaly
with capsular laceration and perisplenic hematoma, the autopsy showed
widespread, relevant lymphadenopathy, associated with a pulmonary and tonsillar
inflammation. The serologic tests were positive for the recent, but no longer active,
Epstein Barr virus infection. Lastly, examination of the histological preparations
confirmed the important, almost systemic inflammatory scenario. The objective of
this work was to analyse the event that led to the death of the young girl, in light of
the main forensic concepts of causal nexus
Chronic pain following inguinal hernia repair: assessment of quality of life and medico-legal aspects
No full textThe aim of our study was to evaluate the quality of life (QoL) of a group of patients who underwent tension-free inguinal hernia repair in light of the possible medicolegal implications. We conducted a retrospective study on the QoL of patients who underwent inguinal hernioplasty. One hundred and fifty patients who answered the SF-36 questionnaire were included in the study. Twenty-six (17.3%) had chronic pain, 18 (12%), sensory deficits, and 106 (70.6%) did not complain of any symptoms. There was no a significant deterioration in QoL compared to the reference population. In the group with chronic pain, 10 patients (38.4%) reported being very limited in performing "physically demanding activities"; 18 (69.2%) reported a deficit of performance in activities of daily living; 8 (30.7%) complained of a reduction of time spent at work because of emotional disorders. In one case the pain was particularly severe and required surgical treatment. The answers obtained through the questionnaire show that tension-free hernioplasty does not degrade patients'QoL. However in the group of patients with chronic pain examined one year after surgery, QoL had deteriorated so much that it affected the employment sphere and the social and relational sphere. Although there is a relatively low incidence and frequency of problems relating to chronic pain following inguinal hernioplasty, chronic pain can sometimes have serious effects on QoL and socio-economic and legal implications
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
Intraoperative recurrent laryngeal nerve monitoring in thyroid surgery: Is it really useful?
No full textThe aim of this study was to evaluate the ability of intraoperative recurrent laryngeal nerve monitoring to predict the postoperative functional outcome and the potential role of this technique in reducing the postoperative nerve palsy rate. Materials and Methods. Between June 2007 and December 2011, 1693 consecutive patients who underwent thyroidectomy by a single surgical team were evaluated. We compared patients who have had a neuromonitoring and patients who have undergone surgery with the only visualization. Patients in which NIM was not utilized (Group A) were 942 against the others 751 (group B). Results. In group A there were 28 recurrent laryngeal nerve injuries (2.97%) of which 21 were transients (2.22%) and 7 were permanents (0.74%). In group B there were 20 recurrent laryngeal nerve injuries (2.66%) of which 14 (1.86%) transients and 6 (0.8%) permanents. Differences between the two groups were not statistically significative. Conclusions. The technique of intraoperative neuromonitoring in thyroid surgery is safe and reliable in excluding postoperative recurrent laryngeal nerve palsy; it has high accuracy, specificity, sensitivity and negative predictive value. Neuromonitoring is useful to identify the recurrent laryngeal nerve and it can be a useful adjunctive technique for reassuring surgeons of the functional integrity of the nerve but it does not decrease the incidence of injuries compared with visualization alone. Its application can be particularly recommended for high-risk thyroidectomies
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
