Patient perspectives of early detection of melanoma: the experience at the Brescia Melanoma Centre, Italy
AIM:
Skin self-examination is usually recommended for early melanoma diagnosis. Given the current lack of a standardized Skin Self-Examination method, we raised the issue about the suitable approach to explain to patients what can be considered a suspicious lesion. Hereinafter, we report the results of a pilot-study carried out at the Melanoma Centre, University Hospital Spedali Civili Brescia, Italy.
METHODS:
A consecutive sample of 200 melanoma patients entered into the Melanoma Prevention Project. A detailed survey revealed who had the first suspicion of the melanoma lesion. When melanoma was Self- or Relative-detected, we investigated the signs/symptoms that had alerted patients with reference to the ABCDE rule. The study included also socio-demographic variables, family history of melanoma, skin type, number and type of nevi, and melanoma features.
RESULTS:
Eighty-seven melanoma had been Self-Detected and 44 Relative-Detected. Patients report most commonly signs/symptoms such as dark colour (58%) and changing in size (47%). Seventy-nine percent of these patients have less than ten nevi and 92% have small and regular moles.
CONCLUSION:
Sometimes the signs of melanoma seem to be easy to identify. Our patients say that they recognized melanoma on the base of the Colour and the Change in size. Therefore, we propose the short "CC" acronym that could facilitate the melanoma self-diagnosis. The aim is to give a short and effective message that leads patients to have the doubt of a suspicious lesion of melanoma so that they seek medical attention

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

A Simple and Inexpensive Image Analysis Technique to Study the Effect of Disintegrants Concentration and Diluents Type on Disintegration
Tablets disintegration is often the result of a size expansion of the tablets. In this study, we quantified the extent and direction of size expansion of tablets during disintegration, using readily available techniques, that is, a digital camera and public domain image analysis software. After validating the method, the influence of disintegrants concentration and diluents type on kinetics and mechanisms of disintegration were studied. Tablets containing diluent, disintegrant (sodium starch glycolate, crospovidone, or croscarmellose sodium), and lubricant were prepared by direct compression. Projected area and aspect ratio of the tablets were monitored using image analysis techniques. The developed method could describe the kinetics and mechanisms of disintegration qualitatively and quantitatively. Sodium starch glycolate and crospovidone acted purely by swelling and shape recovery mechanisms. Instead, croscarmellose sodium worked by a combination of both mechanisms, the extent of which changed depending on its concentration and the diluent type. We anticipate that the method described here could provide a framework for the routine screening of tablets disintegration using readily available equipment
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
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
