Efficacy of laparoscopic sacrocervicopexy for apical support of pelvic organ prolapse.
To evaluate the efficacy of laparoscopic sacrocervicopexy for apical support in sexually active patients with pelvic organ prolapse.
METHODS:
One-hundred thirty-five women with symptomatic prolapse of the central compartment (Pelvic Organ Prolapse Quantitative [POP-Q] stage 2) underwent laparoscopic sacrocervicopexy. The operating physicians used synthetic mesh to attach the anterior endopelvic fascia to the anterior longitudinal ligament of the sacral promontory with subtotal hysterectomy. Anterior and posterior colporrhaphy was performed when necessary. The patients returned for follow-up examinations 1 month after surgery and then over subsequent years. On follow-up a physician evaluated each patient for the recurrence of genital prolapse and for recurrent or de novo development of urinary or bowel symptoms. We define "surgical failure" as any grade of recurrent prolapse of stage II or more of the POP-Q test. Patients also gave feedback about their satisfaction with the procedure.
RESULTS:
The mean follow-up period was 33 months. The success rate was 98.4% for the central compartment, 94.2% for the anterior compartment, and 99.2% for the posterior compartment. Postoperatively, the percentage of asymptomatic patients (51.6%) increased significantly (P < .01), and we observed a statistically significant reduction (P < .05) of urinary urge incontinence, recurrent cystitis, pelvic pain, dyspareunia, and discomfort. The present study showed 70.5% of patients stated they were very satisfied with the operation and 18.8% stated high satisfaction.
CONCLUSION:
Laparoscopic sacrocervicopexy is an effective option for sexually active women with pelvic organ prolaps
Deep pelvic endometriosis (Adamyan IV stage): multidisciplinary laparoscopic treatments.
Few small studies have confirmed the feasibility of laparoscopic colorectal resection for Deep Infiltrating Endometriosis (DIE), albeit with a wide range of complications.
AIM:
The aim of this study is to evaluate retrospectively the feasibility and clinical outcome of laparoscopic segmental bowel resection for DIE.
METHODS:
We have retrospectively reviewed the data of patients undergoing laparoscopic rectosigmoidal resection for bowel endometriosis from January 2000 and June 2008. Data analysis included age, preoperative symptoms, operative procedure, operating room time, intraoperative and postoperative complication, length of stay and Quality of life.
RESULTS:
56 colorectal laparoscopic resection for DIE were performed. No conversion occurred. There were no intraoperative complication; 35 patients had a temporary ileostomy and 15 required reoperation for major complication.
CONCLUSION:
DIE should be managed in specialised centers with a multidisciplinary equipe; it represents a difficult surgery which require a high surgeon skill and it must be practiced considering both the risks and the benefits
Laparoscopic ureteroneocystostomy and vesicopsoas hitch for infiltrative ureteral endometriosis.
The aim of the study was to assess the safety and efficacy of laparoscopic treatment of distal infiltrative ureteral endometriosis with segmental ureteral resection, ureteroneocystostomy, and vesicopsoas hitch. We performed a retrospective analysis of perioperative data and looked at follow-up outcomes of patients with deep endometriosis with ureteral involvement treated by laparoscopic vesicopsoas hitch. Six patients were treated for left ureteral endometriosis in the study period. Four of those were diagnosed during previous laparoscopies. A ureteroneocystostomy (Lich-Gregoir reimplantation procedure) with vesicopsoas hitch was fashioned laparoscopically in all cases, and a double-J stent was applied intraoperatively. There were no intraoperative or postoperative complications and no cases of extravasation of contrast at cystogram one week after surgery. The median follow-up time was 38 months (range 12-56). All patients had normal renal ultrasound or intravenous pyelogram results at one year follow-up. This study confirmed that laparoscopic ureteroneocystostomy and vesicopsoas hitch is a safe and effective option in the management of distal ureteral endometriosis. In view of the small size of this series, multicenter studies are needed to confirm these conclusions

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
