Congenital melanotic macules of the tongue. A case report and brief review of the literature.
No full textCongenital melanotic macules of the tongue (CMMT) are a rare and benign condition that is probably underestimated. We report the case of an African infant with multiple congenital hyperpigmented macules of the tongue. To avoid a difficult-to-perform procedure such as a tongue biopsy, focused clinical monitoring was performed every 3 months for 30 months to detect significant changes. A clinical diagnosis of CMMT was made in the absence of concomitant systemic diseases using the clinical findings, the location on the tongue, the negative family history for melanoma, and the absence of drugs and toxic exposure. Clinical follow-up may be sufficient to monitor CMMT rather than performing a tongue biopsy
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
Palmar lichen planus: an unusual localization
No full textDescriviamo un caso inusuale di lichen planus con esclusivo coinvolgimento a livello palmare, caratterizzato clinicamente da aree ben circoscritte di ipercheratosi sovrastante un eritema violaceo, su entrambi i palmi. Tale patologia si è dimostrata non responsiva alle terapie con vari steroidi topici potenti, tazarotene 0,1% gel e metronidazolo orale. Una completa remissione è stata ottenuta con la PUVA terapia topica. Il caso descritto dimostra l’importanza dell’istologia nei casi di dubbia diagnosi in cui sia presente una cheratodermia palmare e conferma come la PUVA terapia sia ancora un trattamento efficace per il lichen planus, incluso quello palmare. Invece il metronidazolo per via orale, che era stato recentemente proposto come una valida alternativa nel trattamento del lichen planus cutaneo e mucoso, non ha mostrato efficacia nel nostro paziente
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
