Autotransplantation of the Testicle in Paediatric Utilising Microsurgical Technique
No full textThis paper reports on the experience of the Paediatric Surgery Clinic of the University of Bologna in testicular autotransplantation utilising microsurgical techniques. Besides evaluating indications for the intervention, the authors present case histories they have accumulated over twenty months (September 1982-May 1984). Subject to discussion are some notes on surgical technique with particular attention to the dissection of the funiculus and to the construction of microsurgical vascular anastomoses. The short-term and medium-term results of 4 autotransplants are presented and commented upon. © 1985, Georg Thieme Verlag KG Stuttgart, New York. All rights reserved
Microvascular autotransplantation of the testis: The 'refluo' technique
No full textWe think that the microvascular orchidopexy is the best technique for the treatment of the high intraabdominal testis. To prevent the problems related to the performing of the anastomosis between the spermatic and the inferior epigastric arteries we changed the traditional way for microvascular orchidopexy performing the venous anastomosis only, relying on the collateral deferential circle for the arterial supply; we called this technique the 'refluo testicular autotransplantation.' We supported our idea with an experimental investigation in rats and rabbits, with which we confirmed the efficacy of our proposal. This original technique, performed in 41 cases, allowed us to gain three important ends: a) reduction of the age at operation (under two years); b) reduction of the operating time (2 hours); c) improved success rate compared with the Fowler-Stephens technique or staged orchidopexy

No full textDuplication of the Entire Small Intestine - A Case Report
No full textThe authors report a case of duplication of the entire small, intestine manifested by frequent haemorrhages originating from a peptic ulcer located distally to the duplication. The peptic ulcer was provoked by the ectopic gastric mucosa of the duplication. Surgery consisted HstrippingH the mucosa of the duplicated tract according to Wrenn's technique (10). Other surgical methods for treating this malformation are discussed in detail. The literature describing similar cases is reviewed. © 1986, Georg Thieme Verlag KG Stuttgart, New York.

New technic for the treatment of high intraabdominal cryptorchism: testicular autotransplantation with venous anastomosis only
No full textA new technique in the treatment of high intraabdominal cryptorchidism is proposed: testicular autotransplantation with venous anastomosis only. The technique consists in performing microsurgical anastomosis of the spermatic vein and homolateral inferior epigastric vein only for adequate venous drainage, leaving irrigation of testis to the deferential artery alone. We have utilized this technique in 16 cases and excellent results have been achieved. It has permitted performing surgery in younger patients (2 years). Surgical trauma and the duration of the operation are less compared to the Silber technique. There is a higher success rate and the procedure is easy to perform
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
