Cagliari University Hospital (CUH) protocol for immediate alloplastic breast reconstruction and unplanned radiotherapy. A preliminary report
No full textAlloplastic breast reconstruction necessitating postmastectomy radiotherapy (PMRT) is at increased risk for complications such as capsular contracture, infection, extrusion, and poor cosmetic results. However, often the indication for PMRT is not decided until a permanent histological examination with review of the permanent sections is carried out, and the expander has already been inserted. Techniques described to face this issue (delayed-immediate reconstruction and Memorial Sloan Kettering Cancer Center protocol) both have disadvantages
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
Nasal reconstruction with the two stages vs three stages forehead flap. A three centres experience over ten years
No full textINTRODUCTION:
In nasal reconstruction all anatomic layers as cover, lining, and support, have to be replaced to restore proper aesthetics. Forehead skin has been acknowledged as the best donor site to resurface the nose. Traditionally forehead flap reconstruction is performed in two stages, but Millard described an intermediate third stage between flap transfer and pedicle division. This study compared the two methods.
MATERIALS AND METHODS:
The study enrolled 31 patients undergoing total or subtotal nose reconstruction between January 2001 and January 2012. 20 patients underwent to the two-step technique (2S Group), and 11 the three-step technique (3S Group). Thickness of the flap was measured in three different areas. A plastic surgeon not involved in the study completed an evaluation questionnaire to assess aesthetic satisfaction (VAS = 1-10).
RESULTS:
The total number of procedures performed (including revisions) ranged from 3 to 6. The average number of procedures performed in group 2S patients was 4 (range: 3-6) in the group 3S was 3.46 (range: 3-5). VAS mean values were studied with t Student test and were found to be significant.
DISCUSSION:
The timing of thinning of the flap and detachment of the pedicle varies among Authors. There are generally two trends: defatting of the flap before the pedicle transection, performed usually 3 weeks from flap harvesting and defatting a few months after disconnection of the pedicle. We think this technique is suited for defects including underlying structures and particularly for all those defects located in the distal part of the nose (tip and nostrils
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
Multiple melanoma arising on a burn scar and extensive sunburn: A case report and a review of the literature
No full textMelanoma arising in a burn scar is very uncommon. We report a recent case of a female patient in whom two different melanomas arose on a wide back burn scar at different times, focusing attention on three different potential risk factors for melanoma the patient had: sunburns, laser therapy on back and burn scar. © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins
Upper eyelid necrosis and reconstruction after spider byte: case report and review of the literature
No full textSpider bites are not very common, especially in the Mediterranean area, and those affecting the ocular-palpebral region involving reconstructive surgery are particularly rare. In May 2010, the case of a Caucasian 24-year-old female patient was brought to the attention of the Dermatology Department, University of Cagliari, Italy. The patient reported she woke up feeling an intense pain with itching and that also she had noticed a spider of an unknown species on her bed. The dermatosis had affected the right orbital region, where there was a considerable red and violet erythema and a hard edema, not foldable. When the necrosis appeared the patient was treated at the Plastic Surgery Unit where she underwent a reconstruction of the eyelid with a full thickness skin graft from the retroauricular area. The post-operative course was regular with a perfect in-take of the skin graft. When the patient was discharged she was sent to an Entomological University Centre to identify the spider species and the possible venom which caused the skin lesion. The spider which caused the injury has been a Loxosceles rufescens (Dufour, 1820). Loxoscelism is a necrotic arachnoidism caused by the poisonous bite of spiders belonging to the Loxosceles species. It is very important to identify what sort of lesion it is and to treat it in a combined way in order to choose the proper timing for surgery to avoid damages to the eyelid functioning

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
