Utilizzo combinato di medicazioni avanzate e trattamento chirurgico ricostruttivo nelle lesioni dell’arto inferiore: nostra esperienza.
The aim of this article is to demonstrate the effect of the utilization of advanced medications and surgical treatment combined on the healing of ulcers of the inferior. An ulcer is a cutaneous loss of substance having a multifactorial pathogenesis that lead to the loss of normal physiological healing and often complicated by a bacterial sovrainfection. The management of an ulcer of the inferior limb demands a multifactorial approach both clinical and therapeutic. It's mandatory to emphasize that an ideal medication for every lesion does not exist because any single lesion has a different evolution in different phases of the tissue healing. An advanced dressing has the aim of making the lesion heal for second intention or to prepare it for a further surgical treatment. Often coutaneous grafts are used leading to a rapid closure of ulcer. Advanced dressing combined with coutaneous grafts are valid tool to obtain the rapid clousure of a chronic woun
EVALUATION OF POLYURETUHANE DRESSING MATERIAL WITH IBUPROFEN IN THE MANAGEMENT OF SPLIT-THICKNESS SKIN GRAFT DONOR SITE
Evaluation of polyurethane dressing with ibuprofen in the management of split-thickness skin graft donor sites
Background: The authors investigated the
possible effect of ibuprofen when included in polyurethane
dressing foam in the management of pain and healing related
to split-thickness skin graft (STSG) donor sites. The study
focused on the use of a foam dressing, Biatain-Ibu, the
combination of an absorbent hydrophilic polyurethane foam,
Biatain, and the active ingredient ibuprofen as an integral
part of the matrix. Patients and Methods: A prospective
study was conducted from October 2006 to April 2007 and
included 40 patients undergoing surgery for any
reconstructive purposes with the use of STSG. The patients
were divided into two groups in a randomized fashion. In the
first group of 20 patients, the donor sites were covered using
Biatain-Ibu foam dressing. In the second group of 20
patients, the donor sites were closed intra-operatively with
a standard dressing which did not contain any known
healing promoting agent. To evaluate the extent and quality
of the pain experienced by the patients and to score pain
over time, the patients in the study were asked to complete
a form containing a visual analogue scale and answer
questions on the quality of pain and the way normal daily
activities were affected. Results: The combined use of
ibuprofen with bio-occlusive dressings accelerated wound
healing compared to fine-mesh gauze dressings and almost
eliminated pain and discomfort in all patients treated. In
patients receiving topical ibuprofen, itch did not present a
major problem. Discussion: This study demonstrates that the
Biatain-Ibu dressing is a useful tool in the management of
STSG donor sites by providing an optimal environment for
wound healing due to its bio-occlusive properties and by
minimizing pain and discomfort
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
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
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
