RUOLO DELLA MEDICINA RIGENERATIVA NEI PAZIENTI AFFETTI DA SCLERODERMIA
No full textLa sclerodermia è una malattia infiammatoria cronica del tessuto connettivo caratterizzata da fibrosi
interessante la cute il sottocute, i vasi ed altri organi. L’obiettivo del nostro studio è valutare
l’efficacia delle tecniche di medicina rigenerativa (lipofilling ed infiltrazione di cellule derivate dal
grasso del paziente dette Adiposed-derived-stem cells) nel migliorare le sequele della malattia che
spesso affliggono i pazienti sclerodermici. Ci proponiamo di ottenere un miglioramento del
trofismo tissutale, di garantire una fisiologica apertura della bocca e infine di accelerare i processi di
guarigione di ulcere digitali. Sono stati arruolati pazienti affetti da sclerodermia sistemica diffusa,
sclerodermia localizzata morphea e sclerodermia localizzata lineare. Il prelievo del tessuto adiposo
è stato effettuato tramite liposuzione. Per l’ottenimento delle ADSCs il prelievo è stato inviato ad un
laboratorio dedicato. Dopo la coltura in vitro, le cellule sono state infiltrate nel paziente veicolate
con acido ialuronico. Il follow-up è stato eseguito ad 1-3-6-9 mesi ed 1 anno. Già dopo 3 mesi
dall’infiltrazione abbiamo ottenuto un notevole miglioramento del trofismo cutaneo, associato ad
una notevole soddisfazione dei pazienti. Le tecniche di medicina rigenerativa sembrano essere una
valida cura per il miglioramento dei difetti estetici e funzionali nei pazienti affetti da sclerodermia
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Abdominal desmoid tumors. A new reconstructive approach.
No full textINTRODUCTION:
Desmoid tumors are rare soft tissue tumors derived from musculoaponeurotic structures of the abdominal wall musculature. Although they are considered benign tumors because they don't metastasize to other parts of the body, they are clinically considered as malignant for their high tendency on infiltrative growth with local invasion and trend to recurrence after local excision. Several reconstructive techniques are proposed in the literature.
METHODS:
Nine female patients with abdominal desmoid tumors underwent the removal of a mass of tissue running from the skin to peritoneum near the tumor with a safety margin in macroscopically normal tissue at least of 5 centimeters from the edge of the tumor. After wide excision, a polypropylene mesh was placed in the rear muscular pocket without anchoring suture (sliding mesh sutureless hernioplasty)
RESULTS:
No patients had perioperative complications or abdominal wall weakness or an incisional hernia in the following 5 years.
CONCLUSIONS:
We consider this technique of abdominal wall reconstruction after desmoid tumor removal a simple procedure that reduces relapsing events and recurrences of abdominal hernia, reducing tension and pain caused by the traditional suture repair technique
Disfiguring facial hemangioma compromising labial functionality: a case report
No full textHemangiomas are proliferative lesions characterized by increased endothelial cell turnover. Lip hemangiomas can distort lip anatomy and are at increased risk of ulceration and/or bleeding, which lead to impaired function and disfigurement. Surgery can provide active treatment but it can be problematic because vermilion tissue is unique and not found elsewhere on the body. Since there is no similar tissue that can easily be used for reconstructing missing vermilion, its preservation is essential for a satisfactory cosmetic result. We present the case of a 74 year old woman suffering from a large hemangioma of the mid-face and particulary with an angiomatous ulcerated lesion at the level of the lower lip. We describe clinical management and surgical treatment of this pathology
Variations on the Author
Get PDF“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
Get PDFWe 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
Suspected spinocellular carcinoma of the inferior eyelid resulted multiple chalazion.
No full textChalazion is a subacute granulomatous inflammation of the eyelid caused by retention of tarsal gland secretions1 and it's the most common inflammatory lesion of the eyelid. In cases of doubtful clinical presentation the diagnosis with a biopsy and a histopathological examination is important because it can orientate an appropriate surgical treatment. We report a case of a 64-years-old diabetic man, suspected for a spinocellular lesion of the inferior eyelid of the left eye, it resulted unexpectedly a chalazion.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
