Medical liability in organ transplantation procedures.
No full textIn February 2000, a sentence of the Supreme Court of Justice ratified that being the transplantation surgery procedures close dependent, they have to be co-ordinate. Therefore, this kind of surgery presupposes a "multidisciplinary co-operation", where different specialists work at the same time or one after another. For this reason, in the sentence not only the doctor who committed the mistake was held responsible, but also other colleagues that have undervalued his action. Strarting from this sentence, Authors describe the procedure of transplantation in all phases (donor's and receiver's clinical condition, donor-receiver compatibility, surgical treatment, receiver short or long time post- surgical assistance) isolating the cases of receiver damage and analysing in which of these hypothesis of professional liability can be recognised

An alternative to skin graft for superficial surgical defect in oral cancer surgery
No full textIntroduction: After surgery for oral cavity cancer, superficial surgical defects are usually covered with a skin graft that can be harvested with different thicknesses depending on the reconstructive need. Despite its popularity and efficacy, this solution has the disadvantage of excessive harvesting times and scarring of the donor site. Other surgeons have proposed the use of bovine pericardium as a reconstructive solution. Its use in otorhinolaryngology especially after oral cavity surgery has never been reported. Objective: The aim of this manuscript is to present our preliminary experience with the use of a collagen membrane obtained from bovine pericardium in the reconstruction of small and superficial defects after transoral resection of oral cavity tumors. Methods: A bovine collagen membrane was used to cover surgical defects in 19 consecutive patients undergoing transoral resection of small/superficial oral cancers. Photographs were obtained in the postoperative period to follow the healing process. We analyzed the pro and cons of this tool, recorded data on postoperative chewing-, speech- and taste-related quality of life, and tested the most appropriate settings providing the best reconstructive result. Results: The bovine collagen membrane allowed us to cover surgical defects of varying size in different oral sites. Shaping and placement proved to be simple. The membrane facilitated physiologic tissue repair: after one month it was completely absorbed and replaced by the patient's own mucosa. No adverse features were observed in the cohort. Conclusion: A bovine collagen membrane can represent a fast and easy solution in cases of split-thickness defect. Unlike a skin graft, it is not associated with donor site morbidity and allows the patient's own mucosa to be restored with a more physiological result
Malignant external otitis with facial nerve paralysis
Get PDFMalignant external otitis (MOE) is a severe infection of the external auditory canal and the skull base that is often seen in elderly diabetic patients with a high mortality and morbidity rate. in >98% of cases, the causative pathogen is Pseudomonas aeruginosa. Here, we describe a case of MOE associated with facial nerve paralysis in a patient hospitalized. A 62-year-old man was referred to our department experiencing right otalgia, purulent otorrhea, ear loss, and a Grade III right facial nerve palsy according to the House-Brackmann scale. He was affected by uncompensated insulin-dependent type 2 diabetes. The patient had a history of noncholesteatomatous ipsilateral chronic otitis treated with tympanomastoid surgery 10 years before, without any sign of recurrence. After 10 days of specific antibiotic and corticosteroid therapy, symptoms were reduced and the paralysis of the superior branches of the facial nerve had improved, but the persisting swell of the ear canal did not allow a thorough evaluation of the tympanic membrane. Therefore, an explorative tympanotomy was performed, and few days after surgery, the marginalis branch paralysis of the facial nerve had improved according toelectroneurography (ENG) results, and the culture swab showed a polymicrobial flora

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
