Safety and Efficacy of Proctosoll Allevia in the Management of Haemorrhoidal Disease in Adults: A Prospective Randomized Clinical Trial
No full textIntroduction: Hemorrhoidal Disease (HD) is a very common anorectal disorder that affects millions of people around the world and represents a major medical and socioeconomic problem. The aim of the present study was to assess the safety and efficacy of Proctosoll Allevia® in patients affected by symptomatic HD in comparison with the results obtained from a control group.
Materials and methods: From January to February 2019, all the patients referred to the outpatient clinic of Rajalakshmi Hospital, who were complaining of first or second degree hemorrhoidal symptoms, were enrolled in the study. They were randomly assigned to either of the 2 arms. Group 1: patients were treated with the Proctosoll Allevia® and were under a controlled diet. Group 2: patients were only under a controlled diet without any treatment - control group.
Results: A total of 51 subjects were screened and 45 (13 F- 32 M) enrolled in the study. All the patients treated with topical application of the cream showed a statistically significant improvement of symptoms within 14 days from the beginning of the therapy if compared to patients who were treated only with a controlled diet. No major adverse events associated with the use of the new product were recorded.
Conclusion: The treatment of I-II degree symptomatic HD with Proctosoll Allevia® has demonstrated to be promising with a good profile of tolerability, safety and efficacy.

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
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
L'ecografia nella diagnosi prenatale di displasie scheletriche
No full textLe displasie scheletriche sono un gruppo di oltre 400 patologie rare, a prognosi variabile e diverso rischio di ricorrenza. Scopo del presente lavoro è stato rivedere la casistica degli ultimi 30 anni in un singolo Centro di riferimento di ecografia ostetrica, per valutare le possibilità di diagnosi prenatale alle diverse età gestazionali.
Sono stati inclusi nello studio 29 feti riferiti per sospetto di malformazione e 11 feti di donne che avevano avuto un precedente feto con displasia scheletrica (2 casi di ricorrenza). Due neonati sono sopravvisuti, si sono avute 3 morti perinatali, in 18 casi la donna ha richiesto l’interruzione volontaria di gravidanza; gli ultimi 2 casi sono persi al follow-up. Le diagnosi erano: displasia tanatofora (n=8), osteogenesi imperfecta di tipo II (n=4), acondroplasia (n=3), sindrome di Shwachman-Diamond (n=2), disostosi spondilocostale (n=2) ed un caso ognuno di sindrome di Apert, ipocondrogenesi, ipofosfatasia ed ipostaturismo familiare. In 8 casi non è stato possibile effettuare una diagnosi esatta. La diagnosi è stata confermata con biologia molecolare in 13 casi, di cui 3 in epoca prenatale. Aspetti ecografici particolari erano riscontrabili nei casi di ipomineralizzazione, in 2/3 di acondroplasia (soltanto nel 3° trimestre), nei 2 di disostosi spondilocostale e nella sindrome di Apert
Duodenocefalopancreasectomia robotica: definizione di un modello predittivo preoperatorio di difficolta'
No full textAlcune evidenze mostrano che la duodenocefalopancreasectomia minimamente invasiva è associata a risultati migliori rispetto all'intervento chirurgico "open". Tuttavia, durante la fase di apprendimento, la sicurezza del paziente o l'efficacia oncologica potrebbero essere compromesse, sollevando così preoccupazioni sull'attuazione sicura dell'intervento. Il sistema chirurgico Da Vinci potrebbe abbreviare la curva di apprendimento e facilitare questo processo, anche se mancano prove chiare della superiorità della duodenocefalopancreasectomia robotica rispetto ad altri tipi di duodenocefalopancreasectomie mini-invasive (laparoscopica o ibrida) o open. Chiaramente ci sono diverse variabili correlate al paziente ed alla patologia di base che possono rendere un'operazione relativamente "semplice", con esito favorevole, o estremamente complessa, con un difficoltoso decorso postoperatorio. La capacità di prevedere la difficoltà della duodenocefalopancreasectomai robotica in ogni singolo paziente è estremamente importante sia per la selezione dei pazienti che per l'implementazione della learning curve
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
