Laparoscopic hernia repair: a prospective comparison of TAPP and IPOM techniques.
No full textThe aim of the study was to evaluate the safety and efficacy of two techniques of laparoscopic hernia repair: the transabdominal preperitoneal technique (TAPP) and the intraperitoneal onlay mesh technique (IPOM). In May 1992 a prospective randomized trial was initiated to compare TAPP and IPOM. Until October 1994, 115 patients with 148 hernias took part in the trial (59 TAPP and 56 IPOM). The TAPP took significantly longer than did the IPOM. There were no intraoperative complications, conversions to open repair, or postoperative deaths in either group. There were 10 (16.9% of patients) postoperative complications in the TAPP group and 14 (25%) in the IPOM group. The difference was not statistically significant. Neuralgias occurred in 3 cases of TAPP and 11 cases of IPOM (p < 0.05), local hematoma in 6 cases of TAPP and 3 cases of IPOM (NS), and urinary retention in 1 case of TAPP and in no case of IPOM (NS). Recurrences occurred in no cases of TAPP and in 8 cases (11.1% of hernias) of IPOM (p < 0.01). The results of the present report suggest that the IPOM technique for laparoscopic hernia repair should be avoided, whereas TAPP appears to be an excellent technique with no early recurrences

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
