SARS-CoV-2 asymptomatic infection in a patient under treatment with dupilumab
Full text linkWe have read with great interest the letter of the European Task Force on Atopic Dermatitis (ETFAD) on SARS-CoV-2-infection and atopic dermatitis published in JEADV (March 2020)1 in which the authors state: "Targeted treatment selectively interfering with type-2 inflammation such as dupilumab is not considered to increase the risk for viral infections and might thus be preferred ...in a situation such as COVID-19 pandemic".1

No full textBACKGROUND: Few studies have so far specifically addressed referrals for mycological visits to analyze the requests for mycological visits in a tertiary referral centre, with particular regard to the rate of true mycoses, the correlation between correct diagnostic hypothesis and specialization of the referring physicians, and the most frequently misdiagnosed dermatological disorders. METHODS: A number of 415 consecutive patients attending our Mycology Unit for suspected superficial fungal infections were enrolled. Final diagnosis was made on clinical features, history, microscopic and cultural analyses and, when necessary, histology. RESULTS: The results show that 118 patients (28.43%) were diagnosed to be affected with fungi, mainly dermatophytes (57%) and Candida (29%). Among nail referrals, onychoystrophies due to mechanical injuries and psoriasis were the most frequently misdiagnosed disorders. Eczema accounted for the main part of the suspected mycoses of glabrous skin, while tinea capitis was the most common referral for hair diseases. The rate of confirmed dermatomychosis was higher among patients referred by dermatologists than by other physicians. The majority of the study patients had undergone previous therapies, mainly antimycotics. CONCLUSIONS: Clinical assessment is often insufficient for diagnosing cutaneous mycoses. Mycological examination is advisable not only for a conclusive diagnosis but also to avoid unnecessary treatments. Nevertheless, clinical competence is relevant for correct suspicion of dermatomycosis
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
Skin cancers in Italian lung transplant recipients: Incidence and risk factors analysis
No full textOnly a few studies reported the incidence and risk factors of skin cancers in lung transplant recipients. The aim of this study was to determine the cumulative incidence of skin cancers in a cohort of patients undergoing lung transplantation and to define predictors of their development. About 247 consecutive patients receiving lung transplantation at the Thoracic Surgery Unit of University Hospital of Padova between May 1995 and October 2016 were studied. Cumulative incidence of skin cancers was estimated considering death as a competing event. The effect of potential predictors was evaluated with univariate and multivariable Cox models for competing risks. About 37 (15.0%) patients developed skin tumors. The cumulative incidence of any skin cancer was 14.2% at 5 years, 21.4% at 10 years, and 24.3% at 15 years posttransplantation. Age at transplantation, male gender, phototype II, and voriconazole use were independent risk factors for development of squamous cell carcinoma. Only male gender and phototype II were independent risk factors for development of basal cell carcinoma. Since lung transplant recipients have a greater risk of developing skin cancers, the management of these patients needs a multidisciplinary approach, in which dermatologists and transplant physicians have a primary role
Dispelling 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
