A Retrospective Study on Single-Stage Reconstruction of the Ear following Skin Cancer Excision in Elderly Patients
Full text linkEar reconstructive surgery aims to solve the deformities caused by cancer excision. Despite the numerous surgical procedures described, recreating the complex anatomy of the ear still represents a challenge, particularly for young surgeons. The purpose of this exploratory pilot study is to review our experience with single stage reconstruction of the partial defects of the auricle, and propose an algorithm based on defect size, location, and characteristics. We retrospectively reviewed patients who underwent ear reconstruction after cancer excision at our institution between February 2018 and November 2020. The data collected included patients’ demographics, defect characteristics, reconstructive technique used, complications, and outcomes. The patients were evaluated at a minimum follow-up time of 12 months. Forty-six patients were included in the study. The most common cause for ear reconstruction was basal cell carcinoma. The mean area of defect was 4.3 cm2 and the helix was the most frequent location of defect. Two patients experienced post-operative complications. At the one-year follow-up, difference in skin pigmentation was reported in 10 cases, a depressed contour of the ear was found in 4 cases, and moderate ear asymmetry was found in 11 cases. No patient needed a secondary procedure. In conclusion, the proposed reconstructive algorithm represents a reconstructive indication that is simple and characterized by low complication rates and good outcomes for both the patient and the surgeon.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
The Use of ECMO and Free‐Fillet‐Leg Flap for Complex Pelvic Reconstruction: A Case Report
No full textAdvanced sarcoma treatment in complex anatomical regions such as the pelvis poses significant surgical challenges. This report details a case involving a 35-year-old man with recurrent osteosarcoma of the left hemipelvis, who underwent a 16 h surgery for hemipelvectomy and reconstruction using a free tibia and fibula fillet leg flap. The procedure, necessitated by an infected, exposed iliac prosthesis, utilized extracorporeal membrane oxygenation (ECMO) for 8 h to maintain flap viability. The flap, incorporating tibia, fibula, and associated musculature was successfully inset and anastomosed to the left common iliac artery and vein, with additional venous anastomosis to the right iliac vein. Despite postoperative challenges such as venous stasis and intestinal ischemia, necessitating further surgical interventions, the patient achieved mobility with a walker at 3 months post-surgery, with stable conditions observed during a 2 years follow-up. ECMO enabled successful preservation and integration of the free fillet leg flap, demonstrating its potential in complex reconstructive surgeries. Specifically, ECMO may extend free flap viability in complex cases, offering new possibilities for challenging oncological and reconstructive surgeries
A case of necrotizing fasciitis from a pedicure: when beauty centers become life-threatening
Full text linkIntroduction: in a historical moment where there is an increasing use of beauty center, we report a case of necrotizing fasciitis occurred after a pedicure, with the aim of clarifying the safety of these aesthetic treatments. Case report: we discuss a case of left foot necrotizing fasciitis as consequence of removing a plantar callus. The patient is a 49 years old man; he is hypertensive, and diabetic not controlled. We report our experience showing the clinical manifestation and the tricky profile of the patient; then we reflect on the safety profiles of these aesthetic treatments. Discussion: some bacterial infections of soft tissue after pedicure and manicure are reported in Literature. Mycobacteria seems to play a prevalent role, mostly after a peculiar practice of "fish pedicure". Our experience shows how the combination between a patient with complicated profile and poor hygienic measures can have catastrophic consequences. Conclusion: the aim of this article is to raise awareness on the serious consequences that can arise from banal aesthetic procedures. Furthermore, we want to recommend more control over these treatments performed in Beauty Salon, considering the large turnout of people, even clinically sensitive
ALAR BASE LINING GRAFT (ABLG): A NEW TECHNIQUE TO PREVENT AND CORRECT ALAR RETRACTION IN PRIMARY AND SECONDARY RHINOPLASTY
No full textIntroduction: rhinoplasty traditionally represents a difficult challenge for plastic surgeons. The aim of this article is to describe our personal new graft ABLG (Alar base lining graft) in augmentation rhinoplasty, to treat and prevent alar retraction. Materials and methods: in this study, we retrospectively reviewed patients treated with ABLG at our institution between July 2019 and April 2022. We described our personal technique and graft. At a minimum follow-up time of one year, post-operative pictures were taken, and patients were reassessed, evaluating aspects such as global symmetry, shape and contour of the nose, Finally, patients' satisfaction was investigated according to ROE questionnaire. Results: a total of 42 patients were included in the study. They reported a significant satisfactory aesthetic result in nasal image, as the mean postoperative ROE score shows. The alar contracture in secondary rhinoplasty was successfully treated. None of the grafts was extruded or collapsed. Wounds healed without reported major infection. Conclusion: this study has demonstrated that ABLG is a safe graft that contributes to improved functional and aesthetic outcomes, has a high patient satisfaction rate, and a low rate of post- operative complication
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
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
