No. of bitstreams: 0 Previous issue date: 2017fundo A parotidectomia geralmente é realizada enquanto o paciente está sob anestesia geral; no entanto, a sedação com anestesia locorregional pode ser uma alternativa. Métodos Quinze pacientes adultos com tumores parotídeos do lobo superficial foram incluídos neste estudo. O procedimento anestésico consistiu em sedação associada ao plexo cervical e bloqueio do nervo auriculotemporal. A sedação foi gerenciada com base no índice bispectral. Resultados Parotidectomias superficiais foram realizadas em 13 pacientes e ressecções parciais combinadas foram realizadas em 2 pacientes. O tempo cirúrgico médio foi de 118,2 ± 16,4 minutos. A conversão para anestesia geral foi necessária em apenas 1 paciente. Dez cirurgias foram realizadas em nível ambulatorial. Paralisia facial definitiva ocorreu em 1 paciente. Todos os pacientes relataram satisfação total com o procedimento. Conclusão Em casos selecionados, a parotidectomia sob sedação e anestesia locorregional é viável e segura. A seleção cuidadosa dos pacientes e a estreita colaboração com um anestesista são a chave para um procedimento bem-sucedido. © 2016 Wiley Periodicals, Inc. Head Neck 39: 744–747, 2017Background. Parotidectomy is usually performed while the patient is under general anesthesia, however, sedation with locoregional anesthesia could be an alternative. Methods. Fifteen adult patients with parotid tumors of the superficial lobe were included in this study. Anesthetic procedure consisted of sedation associated with cervical plexus and auriculotemporal nerve block. Sedation was managed based on the bispectral index. Results. Superficial parotidectomies were performed in 13 patients, and combined partial resections were performed in 2 patients. The mean operative time was 118.2 +/- 16.4 minutes. Conversion to general anesthesia was necessary in only 1 patient. Ten surgeries were performed on an outpatient basis. Definitive facial paralysis occurred in 1 patient. All patients reported total satisfaction with the procedure. Conclusion. In selected cases, parotidectomy under sedation plus locoregional anesthesia is feasible and safe. The careful selection of patients and the close collaboration with an anesthesiologist is the key to a successful procedure.

    No full text
    Objective: To assess the effect of truncal ligation of the inferior thyroid artery in comparison with ligation of secondary branches as a risk factor for postoperative hypocalcemia. Data Sources: A search was conducted using the Medical Subject Headings and free-text terms “thyroid*” and “truncal ligation*” in PubMed Central, PubMed, Embase, and Latin American and Caribbean Health Sciences Literature databases for trials published between January 1985 and October 2016. A Google search with the same terms, and a “snowball” approach was designed to retrieve the largest number of articles. Review Methods: Controlled trials (randomized or not) of adults who underwent total/bilateral subtotal thyroidectomy were searched, and truncal ligation versus nontruncal ligation of the inferior thyroid artery was compared. Data were acquired following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Methodological quality of randomized controlled trials was assessed in accordance with Cochrane Collaboration guidelines, and for nonrandomized controlled trials, the Newcastle-Ottawa quality assessment scale for cohort studies was used. Pooled results are presented as risk differences with a random effects model. The main outcome was postoperative temporary and definitive hypocalcemia. Results: We found 11 nonrandomized controlled trials and nine randomized controlled trials with 1940 patients: 977 patients in the trunk ligation group and 963 patients in the nontruncal ligation group. The risk difference for biochemical hypocalcemia was 6% (95% confidence interval [CI]: 2% to 11%), for symptomatic hypocalcemia 6% (95% CI: 1% to 10%), and definitive hypocalcemia 0% (95% CI: 21% to 1%) in the whole group. Conclusions: Truncal ligation of the inferior thyroid artery increases the risk of temporary and symptomatic hypocalcemia but not the risk of definitive hypocalcemia.Objective: To assess the effect of truncal ligation of the inferior thyroid artery in comparison with ligation of secondary branches as a risk factor for postoperative hypocalcemia.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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 text
    We 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
