The laparoscopic Vecchietti technique for vaginal agenesis
No full textOBJECTIVE: To evaluate surgical, long-term anatomic and functional results of the laparoscopic Vecchietti procedure to treat women with vaginal agenesis. METHODS: Retrospective analysis of 86 women treated at the Department of Gynecology and Obstetrics at the University of Verona, Italy. Data were analyzed based on surgical results and postoperative sexual satisfaction. Depth and diameter of the neo-vagina was determined. The characteristics of the neo-vaginal mucosa were investigated by vaginoscopy. Patients reported frequency, satisfaction, and any difficulties found at intercourse. RESULTS: Functional success was obtained in 98.1% and anatomic success in 100%. In all patients, at 1 year, the mucosa was pink, trophic, and moist. Two fingers were introduced easily into the neo-vagina in all cases. All patients, which decided to have sexual intercourse, defined these as satisfying within 6 months. CONCLUSIONS: Laparoscopic procedure used in this study is simple, safe, and effective. Anatomical and functional results obtained suggest this laparoscopic procedure as the treatment of choice for this syndrome
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
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
Umbilical endometriosis: A radical excision with laparoscopic assistance
No full textAbstractBackgroundUmbilical endometriosis represents the most common site of cutaneous endometriosis. Although its treatment is typically surgical, in literature the approach used is variable and extends from diathermocoagulation to omphalectomy. Such superficial treatments for umbilical endometriosis can predispose the patient to a relapse of the disease. We here present seven cases of umbilical endometriosis treated with radical surgery with a laparoscopically-assisted approach, with a complete and long-term disease-free follow-up.CasesSeven cases of umbilical endometriosis, four of which relapsing from a prior superficial treatment, were treated radically with a laparoscopically-assisted approach, with a long-term disease-free follow-up.ConclusionAlthough a medical treatment can be considered, the treatment of choice in these patients should be that of excisional surgery so as to avoid lesion relapse and the risk of oncogenic transformation. Despite umbilical endometriosis is a rare finding, this relatively small case series treated by laparoscopically-assisted omphalectomy shows a complete resolution of the lesion and symptoms along with good aesthetic results at a long-term follow-up
Laparoscopically assisted uterovestibular anastomosis in patients with uterine cervix atresia and vaginal aplasia
No full textObjective: To describe the surgical technique and the long-term anatomic and functional results of laparoscopically assisted uterovestibular anastomosis. Design: Descriptive study. Setting: Tertiary referral center. Patient(s): Twelve consecutive patients with uterine cervix atresia and vaginal aplasia. Intervention(s): Laparoscopically assisted uterovestibular anastomosis was performed in all patients. Follow-up assessments at 1, 6, and 12 months included pelvic examination, transvaginal ultrasonography, and, in selected cases, vaginoscopy and hysteroscopy. Subsequent follow up was done by referring physicians or by means of telephone interview. Mean follow-up was 6 years. Main Outcome Measure(s): Intra- and postoperative characteristics and anatomic and functional outcome. Result(s): The surgical procedure was successful in all cases and all of the women have experienced regular menstruation. At 6-month follow-up, mean vaginal length was 6 cm and at least 80% of neovaginal epithelium was iodine-positive in all patients. Six women were sexually active during follow-up without difficulty. None have yet attempted to seek a pregnancy. Conclusion(s): The study shows the safety and effectiveness of a laparoscopic approach to uterovestibular anastomosis in women with cervical atresia and vaginal aplasia. In these patients, we believe that conservative surgery should represent the first therapeutic option. A longer follow-up is needed to assess pregnancy rates and outcome
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
