Free flap loss caused by heparin-induced thrombocytopenia and thrombosis (HITT) : a case report and literature review = Trombocitopenia eparino-indotta e trombosi (HITT): Una causa sottostimata di fallimento di lembi liberi : Case report e revisione della letteratura
Full text linkHeparin-induced thrombocytopenia and thrombosis (HITT) represents a dramatic condition that is difficult to diagnose because of nuanced clinical presentation. Therefore, in every case of microvascular thrombosis during heparin-therapy prompt suspicion about HITT is necessary to avoid flap necrosis. We present a case of HITT which, as the 8 other articles reviewed, clearly shows that HITT is difficult to diagnose and complex to manage. Microvascular reconstruction is the first choice in head and neck reconstruction; unfortunately, dramatic outcomes in free flap surgery due to unpredictable thrombotic events are still reported in the English literature. More knowledge is required about HITT and reaching a consensus about thrombotic prevention in microsurgery could be helpful. Furthermore, a careful anamnesis can help minimise unexpected situations
Resorbable Materials for Reconstruction of the Orbital Floor in Children
No full textThe best treatment of pediatric orbital fractures is debated and different strategies are proposed in the literature. Resorbable materials, due to their features and the specific requirements of the pediatric population, seem a very suitable choice. The authors present their experience by describing 3 cases and explaining their mesh modeling technique. Two fractures were caused by accidental falls, whereas the other resulted from aggression. Clinical and radiological evaluation (computed tomography scanning) was performed before surgery. No complications occurred either immediately after surgery or in the long term (maximum follow-up of 3 y). As there has been little experience of the use of resorbable mesh in maxillofacial pediatric traumatology, the authors describe their technique, which may facilitate the use of this material in orbital fractures
Sinovite pigmentosa villo nodulare dell’articolazione temporomandibolare: caratteristiche istologiche e trattamento chirurgico=Pigmented villonodular synovitis of temporomandibular joint: pathological aspects and surgical treatment
No full textPigmented villonodular synovitis (PVNS) is an uncommon, benign, tumour-like disorder of unknown etiology affecting synovium-lined joints, tendon sheaths, and bursae. It results in proliferative, locally invasive lesions, usually presenting in monoarticular form in adults. PVNS rarely presents in the temporomandibular joint (TMJ). The treatment of choice is complete surgical excision of the lesion, followed by immediate reconstruction. We report a case of PVNS with masticatory space involvement, and focus on the pathological aspects and surgical treatment of the lesion
Parry Romberg Syndrome and linear facial scleroderma : management in pediatric population
No full textAmong all different types of cutaneous scleroderma, Parry Romberg syndrome and linear scleroderma “en coup de sabre” typically involve the visage. Gradual degeneration of the tissues, from the skin up to the bone, is the stigmata of the diseases and the range of clinical manifestations is wide. They typically start during childhood and slowly progress before stabilizing. Considering the gravity of the associated deformity and its impact on facial function and appearance, we strongly advocate a prompt intervention that however must be tailored on paediatric patients. There is not a general consensus on hemifacial atrophy treatment, but autologous fat grafting has been proved to be a suitable technique, due to its low morbidity, repeatability and efficacy in correcting volume defects and in improving skin texture. Following the same concept of safeness and non-invasiveness we propose 3D stereophotogrammetric acquisitions as a possible tool for the pre- and post-surgical follow up, indispensable to evaluate the surgical results. We present our case series composed of 8 paediatric patients, aged between 11 and 17 years, who underwent several lipofilling procedures, from 2012 to 2016. Starting from 2015, 3D stereophotgrammetric data has been obtained
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
LE RELAZIONI COMMERCIALI E MARITTIME TRA FANO E SEGNA

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
