Pilomatrixoma: A case report
No full textPilomatrixoma (Malherbe's calcifying epithelioma) is a benign tumor that arises from the matrix of hair follicles. It has the propensity to occur in the head region and often involves the eyelid or eyebrow. Although pilomatrixoma is well known to dermatologists and ophthalmologists, it is not widely recognized among otolaryngologists as a cause of a solitary, round, firm, intradermal nodule in head skin in a child. We report the findings in a 5-year-old child who developed a single pilomatrixoma of the right upper eyebrow
L'Arco di Traiano di Ancona tra passato, presente e futuro.
No full textIl libro è stato stampato in occasione del cinquantennale del Rotary Club Ancona Conero. Il Club ha voluto richiamare l'attenzione su questa importante opera d'arte con la redazione e pubblicazione di uno scritto. Il Rotary Club è stato sempre sensibile alla salvaguardia della ricchezza culturale ed artistica del territorio e attento alla necessità di mantenerne viva la memoria. A causa della pandemia i lavori per un restauro dell'opera, con la partecipazione dell'Autorità di Sistema Portuale del Mare Adriatico Centrale e la supervisione della Soprintendenza Archeologia, Belle Arti e Paesaggio delle Marche, sono stati rinviati ma saranno a breve realizzati
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
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
Nasal paraganglioma. A case report
No full textNonchromaffin paragangliomas or chemodectomas arise in paraganglia distributed in various parts of the body. The jugular bulb, the vagal body and the bifurcation of the carotid artery are the most common sites of origin of paraganglioma in the head and neck region. Paragangliomas in the nose and paranasal sinuses are extremely rare and very few cases of definite paraganglioma arising primarily in the nose or paranasal sinuses have been reported. The paraganglioma is a slow-growing tumour that produces nasal obstruction, profuse epistaxis and facial swelling. Complete excision of the glomus tumour is normally curative. We report a case of nasal paraganglioma and discuss the diagnosis and therapy
Modified reverse septal flap: A surgical hint
Full text linkEndoscopic resection with transnasal craniectomy (ERTC) and skull-base reconstruction (SBR) are effective techniques for sinonasal/skull-base malignancies treatment. Endoscopic endonasal SBR techniques are mainly based on homologue-free grafts with excellent outcomes, but alternative techniques can be used such as regional vascularized pedicled flaps or local pedicled flap-like Hadad–Bassagasteguy nasoseptal flap and the septal flip flap (SFF). The purpose of this article is to describe an inferiorly based septal flap aimed to promote mucosal healing and improve patients’ quality of life. We reported a clinical case of 51-year-old female affected by olfactory neuroblastoma, Hyams-II, Kadish-INSICA-B treated with unilateral ERTC and SBR with fascia lata, SFF, and modified reverse septal flap (mRSF). The mRSF harvesting is described in detail, to obtain a lower hinged flap with random vascularization, which can be rotated to cover the exposed bone of the nasal cavity floor. Endoscopic evaluations immediately showed rapid healing with a minimal amount of nasal crusting, despite the adjuvant treatment and the short time since the surgery. This surgical technique is a simple and viable way to boost nasal healing after endoscopic endonasal surgery and for nasal floor resurfacing after septal removal following a unilateral ERTC

No full textDispelling 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
