Persistent Mullerian duct syndrome associated with transverse testicular ectopia: A case report
No full textThe authors describe their experience in the treatment of a child, male phenotype, with a Transverse Testicular Ectopia (TTE), associated with a rudimentary uterus and two Fallopian tubes (Persistent Mullerian Duct Syndrome = PMDS). The boy was transferred to the Pediatric Surgical unit of the university of Bologna from another hospital where at operation for bilateral cryptorchidism the diagnosis had become apparent. In order to exclude the presence of PMDS it is very important that an abdominal exploration should be performed in all cases of TTE where the testes are undescended. The diagnosis was made by an occasional detection: it is very important, when a TTE in which the testes are undescended is found, to perform the abdominal exploration, in order to exclude the presence of PMDS
The varicocele in pediatric age: 207 cases treated with microsurgical technique
No full textBetween 1984 and 1995, 207 boys afflicted by varicocele have undergone surgery. They were all treated employing a venous microvascular termino- terminal anastomosis between spermatic and inferior epigastric veins. The recurrence rate with this technique (3%) is much lower than Ivanissevich's one (nearby 15%). The clinical results are optimal, with disappearance of varices in the majority of cases and improvement of the testicular trophism in the remainder. This technique enables the establishment of an immediate and physiological testicular venous outflow essential for testicular growth and development
Pediatric bronchiectasis
No full textThe term “bronchiectasis” is derived from the Greek “bronchion”, meaning windpipe, and “ektasis”, meaning stretched. Bronchiectasis is characterised by the permanent dilatation of bronchi with destruction of the elastic and muscular components of their walls

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
