Caso clinico di una paziente operata di mastectomia con ricostruzione tramite TRAMF
No full textViene presentato il caso di una paziente sottoposta a mastectomia radicale sinistra per
carcinoma con successiva ricostruzione differita tramite lembo di retto dell’addome,
risultata in completa perdita del lembo a causa di estesa necrosi, la cui rimozione ha
reso necessaria la riparazione tramite lembo epigastrico. La paziente presentava
un’ampia regione cicatriziale retraente che coinvolgeva tutta la regione mammaria sinistra
e l’epigastrio omolaterale. Dopo numerosi tentativi per inserire e mantenere in sede
l’espansore, la paziente è stata inserita nel protocollo di lipofilling. Gli effettivi e talora
sorprendenti risultati da noi ottenuti clinicamente tramite la tecnica del lipofilling
nella quasi totalità delle pazienti, ci ha indotto a ritenere opportuna anche in questo
caso la valutazione dei miglioramenti strutturali dei tessuti trattati da un punto di vista

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
Clitoroplastica e ricostruzione chirurgica delle grandi labbra in mosaicismo X0/XY: Case report
No full textThe goal of genital correction surgery is to create a cosmetic and functional outcome preserving the sensitivity. A case of correction for hypertrophy of the clitoris and labia majora is described. A 46 years old women, diagnosed at infancy with X0/XY mosaicism, presented in early childhood, hypertrophy of clitoris and labia majora. She underwent surgery to remove gonads in infancy, but she asked for reduction clitoroplasty and labia majora only after a long psicotherapic support. A small area of the clitoris to be preserved was marked. Neurovascular bundle was carefully separated from the corporal tissue that was cut off. Later the estimated amount of skin and fat to be removed from labia majora was marked. At 12 months after surgery, the patient's external genitalia had reached a normal appearance. The sensitivity of the surgically reduced clitoris had preserved and labia majora aspect had a good cosmetic result. © Capsula Eburnea, 2010
Interaction Between Breast Cancer Cells and Adipose Tissue Cells Derived from Fat Grafting
No full textBackground Adipose tissue transplantation has the benefit of providing both regenerative and aesthetic outcomes in breast cancer treatment. However, the transplanted tissue can stimulate the growth of residual cancer cells.
Objectives The aim of this study is to identify the interactions between adipose tissue cell subpopulations and human cancer cell lines.
Methods Intact adipose tissue from lipofilling procedures as well as fibroblasts derived from adipose tissue, were cocultured in the presence of MDA-MB-231, MCF-7 e ZR-75-1 breast cancer cell lines. The influence on cancer cell lines of fibroblasts, induced to differentiate into specific adipocytes, was also assayed.
Results All cancer cell lines displayed a significant increase in proliferation rate when cocultured in the presence of either intact adipose tissue or induced adipocytes. To a lesser extent, uninduced fibroblasts stimulate breast cancer cell proliferation.
Conclusions Recent studies have shown that the microenvironment surrounding breast cancer cells may stimulate growth and promote progression of residual cancer cells when surgery is performed on the main tumor mass. Accordingly, the graft of adipose tissue could potentially promote or accelerate the development of a subclinical tumor or support its locoregional recurrence. Our data suggest that adipocytes have a remarkable influence on the proliferation of cancer cell lines. The oncological safety of the lipofilling procedure outcome is still debated; thus, further studies and consistent follow-up examination are needed
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
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
