No full text"Double N":Evolution of the Surgical Technique for Laparoscopic Herniorrhaphy After 10-Year Experience in a Single Center
No full textINTRODUCTION:
We describe our experience with the use of a modified technique for laparoscopic internal inguinal ring closure (peritoneal incision and double "N" stitch placement). We evaluate the technique in terms of feasibility, efficacy, and safety.
MATERIALS AND METHODS:
From November 2003 to March 2014 we performed 1700 herniorraphies by laparoscopy. We selected 123 patients treated with the "double N" technique by the same surgical team, and we reviewed their notes analyzing demographic data, operative times, intra- and postoperative complications, and recurrence rate. The technique used is a modification of the Schier technique. Our technique consists of a partial lateral peritoneal 180° incision around the internal inguinal ring and in the placement of a double stitch. The first stitch is used to approximate the muscles with the inguinal ligament, and the second one is used to close the peritoneum above them.
RESULTS:
The female to male ratio was 22:101. Mean age at surgery was 4.3 years (range, 1 month-12 years). Mean operative time was 30 minutes (range, 20-50 minutes). There were 60 bilateral cases. There were no intraoperative complications. Two patients had reactive hydrocele treated conservatively, and 1 patient developed umbilical infection. We did not identify any recurrence.
CONCLUSIONS:
Our early results suggest that the "double N" laparoscopic technique to close the internal inguinal ring in children is safe and efficient. We therefore suggest using this approach in children with a patent internal inguinal ring of >1 cm. The recurrence rate is low, but it should be better assessed by studies with longer follow-up

Laparoscopic Nissen fundoplication with fibrin glue: experimental study on pigs.
No full textNowadays laparoscopy shows a great development in the pediatric age group. Pediatric surgeons are now able to study the possible applications in pediatric surgery of this new and fascinating procedure. A mandatory laparoscopic training to perform any important operation is clearly essential. Only a few cases of Nissen fundoplication have been reported in children. We suggest this experimental study in which we add a technical modification by using fibrin glue to tighten the gastric wrap on the esophagus positioning only two stitches at the extremes of the suture. The results were interesting and we think it an excellent starting point for a future clinical application of this new technique
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
