Lymph Nodes of the Perimandibular Area and the Hazard of the Hayes Martin Maneuver in Neck Dissection
Objective To provide an anatomic description of submandibular nodes at risk of being left undissected during neck dissection (ND) and to assess whether the Hayes Martin maneuver is a safe procedure in oncologic surgery of level IB nodes. Study Design Prospective study. Setting Academic medical center. Subjects and Methods We recruited 62 patients who were candidates for level IB ND. Perifacial nodes (PFNs) were identified and their characteristics noted. The Hayes Martin maneuver was simulated, and its oncologic safety was tested. Results The study included 63 NDs. PFNs were identified in 84% of cases: their number ranged from 0 to 5, and their mean greatest diameter was 12.45 mm. Anterior PFNs were found to be in direct contact with the marginal mandibular nerve. In 59% of NDs, the Hayes Martin maneuver would have failed to remove all PFNs. Conclusions The PFNs were identified in 84% of cases and ranged in number from 0 to 5. In some cases, the distinction between retro- and preglandular nodes and PFNs is not useful. The Hayes Martin maneuver may not be oncologically sound for complete treatment of level IB nodes
Perimarginal lymph nodes: an undervalued entity in oral cancer
PURPOSE:
In a previous study, we gave a surgical description of a group of lymph nodes in the submandibular area at risk of remaining undissected during neck dissection (ND) for which we have proposed the term "perimarginal nodes" (PMNs) due to their proximity to marginal mandibular nerve (MMN). The aim of this study is to evaluate prevalence of PMNs involvement in oral cavity squamous cell cancer (OCSCC) and to verify if metastases are related to primary tumor characteristics or to the state of the neck.
METHODS:
We recruited a total of 39 consecutive patients diagnosed with OCSCC candidate to ND. Histological characteristics of PMNs were analyzed and the incidence of metastases in relation to the primary tumor characteristics were noted.
RESULTS:
PMNs were found to be involved with metastases in 8 patients (20.5%). No characteristic of the primary tumor seems to influence the metastatic involvement of the PMNs.
CONCLUSIONS:
PMNs represent a frequent site of micro-metastases in patients diagnosed with OCSCC regardless of other characteristics of the primary tum
Narrow-band imaging pattern classification in oral cavity
Narrow-band imaging is widely used in the diagnostic work-up of oral lesions. Different oral subsites present three epithelial types (1, 2a and 2b), each with a different structure and function. The aim of this study was to analyse and describe the different vascular patterns seen on narrow-band imaging according to oral epithelial type and histology
A Bibliometric Portrait of Contemporary History of Economic Thought
This chapter is an attempt to apply bibliometrics for describing the ways in which scholars do their work in the history of economic thought (HET) field. The field is operationally defined as limited to the research articles published in the six professional journals indexed in the Web of Science database, namely History of Political Economy, The European Journal of the History of Economic Thought, the Journal of the History of Economic Thought, History of Economic Ideas, Research in the History of Economic Thought and Methodology, History of Economic Thought and Policy. HET represents a small and stable niche in the economic literature, with a production relatively concentrated in a few countries. Writing HET is a male individual enterprise, and collaboration in the form of multi-authored papers is rather uncommon. Books still represent a big part of the primary sources used by HET. Historians cite a relatively small number of journals, and references are relatively concentrated

Orizzonti mantovani. Spunti e dinamiche paesaggistiche ne L'Illustrissimo di Alberto Cantoni
In the literary production of Alberto Cantoni, short story writer and novelist between the nineteenth and twentieth centuries, the novel L'Illustrissimo is highly important both because it is the last publication of the author, from Pomponesco, a small town a few kilometers south of Mantua, both because it summarizes in a single text the different nuances and different directions that his writing has taken over the course of his literary career, also due to a writing and processing time that embraces the entire span of years of his career itself. In the foreground, in addition to the numerous and brilliant characters, one of the protagonists is the Mantuan landscape which, not a simple background, becomes a true literary parameter which in different and significant ways affects the purposes and mechanisms of the novel
Equità ed efficienza nella tassazione dei redditi personali : fondamenti teorici e linee di riforma
In questo capitolo ci soffermiano in primo luogo sulla riforma italiana degli anni '70, sottolineando limiti e compromessi evidenti nella sua concezione e nella sua applicazione. Delineiamo poi la storia analitica di questo trentennio, sottolineando i passaggi per noi cruciali. Sul piano delle proposte operative o delle elaborazioni più generali, il Rapporto Meade, la riforma Reagan, la Dit introdotta nei paesi nordici ed, infine, le proposte elaborate dal Panel diesperti nominati dal Presidente Bush, costituiscono i riferimenti essenziali.
In conclusione tenteremo una lettura delle più recenti vicende del nostro Paese, inquadrandole nel dibattito internazionale

O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaA pretensão desta dissertação intitulada O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes é investigar a relação entre o sentir e o puro pensar, usando como referência a poesia O Guardador de Rebanhos, de Alberto Caeiro, que apresenta de forma evidente o tema; e como este assunto é tratado nas Meditações Metafísicas de René Descartes, também de forma claramente visível. Podemos perceber em ambos os autores, uma diplopia, uma espécie de duplo olhar sobre a relação sentir e puro pensar. No primeiro capítulo vou falar sobre a tese do duplo olhar de Descartes, a respeito da relação sentir e puro pensar na leitura de Merleau-Ponty, salientando a visão de natureza. No segundo capítulo, parto da leitura das três primeiras Meditações Metafísicas para caracterizar a tensão que se pode verificar entre Descartes e Alberto Caeiro quando se referem ao puro pensar. O foco principal de Descartes, nas três primeiras Meditações, é o pensar puro, e neste ponto Alberto Caeiro critica o pensar puro. No terceiro capítulo, analisando as três últimas Meditações, percebe-se que há uma virada no pensamento de Descartes, no qual o autor inverte seu ponto de vista, aproximando-se da idéia de Alberto Caeiro. No quarto capítulo, mostrarei a leitura que outros autores fazem acerca do sentir e do pensar na obra de Alberto Caeiro, mostrando que assim como Descartes, este também ostenta uma diplopia, não do sentir, mas do pensar. The pretension of this work entitled O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes is to investigate the relationship between the feeling and the pure thinking, using as reference the poetry O Guardador de Rebanhos, by Alberto Caeiro, that presents in an evident way this theme; and as this subject is treated in René Descartes' Metaphysical Meditations, also in a clearly visible way. It is possible to notice in both authors, the diplopy, a sort of double look about the relationship between feeling and pure thinking. The thesis about Descartes'double look regarding the relation of feeling and pure thinking, in Merleau-Ponty reading, pointing out the nature vision, will be treated in the first chapter. In the second chapter, I start from the reading of the first three Metaphysical Meditations to characterize the tension that can be verified between Descartes and Alberto Caeiro when they refer to the pure thinking. Descartes' main focus in the first three Meditations is pure thinking and, in this point, Alberto Caeiro criticizes pure thinking. In the third chapter, analyzing the last three Meditations, it is possible to notice that there is an alteration in Descartes' thought, in which the author inverts his point of view, approaching of Alberto Caeiro's idea. In the fourth chapter, I will show the reading that other authors do concerning feeling and thinking in Alberto Caeiro's work, showing that as well as Descartes, this also shows a diplopy, not of feeling, but of thinking
Lobbying for change as a new theory and practice of active citizenship: author interview with Alberto Alemanno
Do you believe that lobbying is a vehicle for representing the interests of some rather than all, meaning its actors can never be a force for good? Alberto Alemanno, author of Lobbying for Change: Find Your Voice to Create a Better Society, might convince you of the contrary. This interview with Barbara Aubin, LSE Public Affairs, reflects on the importance of engaging with our political representatives, holding them accountable and lobbying for the causes we deeply care about as fundamental elements of a healthy democracy
