    Efficacy of Iralfaris shampoo in the treatment of scalp psoriasis: a videodermoscopy evaluation prospective study in 70 patients

    No full text
    Aim. This work has the aim to test the sensibility of VSCAPSI method in the evaluation of effectiveness of a medicated shampoo for the treatment of scalp psoriasis. Psoriasis is a chronic inflammatory skin disease histologically characterized by proliferation and loss of differentiation of keratinocytes, angiogenesis with vasodilatation and increased permeability, and inflammation. Scalp involvement is a common clinical feature of psoriasis, that is present in the 25% of patients who suffer of it. Videodermoscopy (VD) permits a magnified view of the surface components of the epidermis and papillary dermis, which are not visible to the naked eye, together with the ability to capture digitally the viewed images and to store them for later use. Moreover videodermoscopy is a non-invasive technique, used to analyze cutaneous peripheral microcirculation. Therefore VD could be an useful tool in evaluating the efficacy of treatments for scalp psoriasis. The clinical benefit of currently available medicated shampoos for the treatment of scalp psoriasis is restricted, due to their limited efficacy, low cosmetic appeal and safety and tolerability problems. Therefore effective and safe products are needed especially for the long term management of scalp psoriasis. A specific shampoo designed for the scalp hygiene in psoriatic patients has been recently developed. This shampoo contains urea, glycolic acid, salicylic acid, icthyol pale and laureth 9 (polidocanol). Aim of the study was to evaluate in a 12-week prospective monocenter, open-study the efficacy and tolerability of an emollient, keratolytic shampoo (Iralfaris shampoo ISDIN, Barcelona; Ir-S) applied three times a week in patients with scalp psoriasis. The efficacy of the shampoo has been valuated with VSCAPSI. Methods. Seventy subjects with mild to moderate/severe scalp psoriasis were enrolled in the trial, after their informed consent. Efficacy was assessed using a specific and validated videodermoscopy scalp psoriasis severity index (VSCAPSI) score, performed at baseline, after 45 and 90 days. Patients were evaluated for itching. Results. VSCAPSI score at baseline was 8.5. Ir-S induced a significant reduction of VSCAPSI score in comparison with baseline value both after 45 and 90 days of treatment. The use of shampoo lead to a progressive reduction of VSCAPSI score getting a score of 4.2 at T45 and a score of 4.0 at T90 (P=0.001 vs. baseline). The use of Ir-S has significantly reduced the percentage of patients reporting itching sensation. Conclusion. The treatment was safe and well-tolerated with an high cosmetic acceptance. Ir-S is a good alternative to other medicated shampoo in the treatment of mild to moderate scalp psoriasis. Moreover, in the treatment of severe scalp psoriasis, it can lead to an improvement if associated with topical medications

    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
