Transvaginal mesh for POP: an endless story with a strong present and future in Italy and in all Europe
No full textVaginal vault prolapse is observed with increasing frequency in the era of increasingly aging populations. Various surgical techniques have been established, varying in performance, difficulty, outcomes and most importantly complications. A bilateral sacrospinous colposuspension technique (BSC) with a corresponding mesh prosthesis was developed using a direct I-Stitch fixation of the 38 microgram mesh from the vaginal apex or uterine cervix to the sacrospinous ligament or the parasacral tendinous region for the treatment of an anatomical central pelvic floor defect. As a minimally invasive approach with the potential for conservation of the uterus, this technique should be applicable to all age groups including the increasingly frequent elderly patient with significant co-morbidities. © 2019, Galenos Publishing House.

Effectiveness and Safety of Posterior Vaginal Repair with Single-Incision, Ultralightweight, Monofilament Propylene Mesh: First Evidence from a Case Series with Short-Term Results
No full textObjective: The use of transvaginal mesh is controversial, and over time, multiple surgical methods for the treatment of posterior vaginal prolapse (PVP) have been proposed including different surgical approaches and techniques. To date, no clear conclusion has been reached about the use of mesh for reinforcing transvaginal posterior repair. The aim of this study was to evaluate the feasibility, safety, and effectiveness of a novel, ultralightweight mesh for the treatment of PVP.
Methods: We performed a single-center, prospective observational study on consecutive patients referred for primary or recurrent, symptomatic stage II PVP (according to the international Pelvic Organ Prolapse Quantification System) from April 2017 to September 2018. In all patients, transvaginal posterior repair was augmented with a single-incision, isoelastic polypropylene mesh. Data about the postoperative outcomes were collected until December 2019.
Results: A total number of 15 patients were included. The median follow-up after surgery was 18 months (IQR = 14). Surgery was completed in all cases without complications. Regarding the anatomical outcomes (as measured according to POP-q classification), a significant improvement was observed in terms of Bp, D, and C (p < 0.05). The functional outcomes were significantly ameliorated after surgery, with a reduction of bulge symptom, stypsis, incomplete evacuation, and excessive staining (p < 0.05). The quality of life was significantly improved in the majority of patients (p < 0.05). Median patients' satisfaction rate was 100% (IQR = 22.5%). Neither early nor late postoperative complications occurred.
Conclusions: Single-incision, ultralightweight polypropylene meshes were safe and highly effective in the treatment of PVP. As our study has some limitations, further large, controlled studies are needed
Safety and efficacy of vaginal hysterectomy in the large uterus with the LigaSure bipolar diathermy system.
No full textOBJECTIVE: This study was undertaken to assess safety and efficacy of vaginal hysterectomy in case of large uterine size (> or = 250 g) using the LigaSure bipolar diathermy (Valleylab, Boulder, CO).
STUDY DESIGN: In a retrospective study, medical records of 102 patients who underwent vaginal hysterectomy and who had uterine weight (evaluated after surgery) 250 g or greater were reviewed. All hysterectomies were performed by using the LigaSure vessel sealing system to secure vascular pedicles (uterosacral-cardinal, uterine and ovarian and round ligaments).
RESULTS: Of the 102 vaginal hysterectomies, 99 were successfully performed (97.1%; 95% confidence interval, 91.6-99.4%), whereas a conversion from the vaginal to the abdominal route was required in 3 cases. The median uterine weight was 455 g (range, 241-1913 g). The weight of the largest uterus successfully removed vaginally was 1600 g, without intraoperative and postoperative complications. The median operative time was 50 minutes (range, 25-50 minutes).
CONCLUSION: The current study confirms that very large uterine volume does not represent a real obstacle to perform vaginal hysterectomy and that results in a safe and effective technique in cases of uterine weight 250 g or greater.Objective: This study was undertaken to assess safety and efficacy of vaginal hysterectomy in case of large uterine size (≥ 250 g) using the LigaSure bipolar diathermy (Valleylab, Boulder, CO).

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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
