Davide Fieschi: a pioneer of plug repair in groin hernia surgery.
No full textPlug repair actually represents one of most recommended procedures in open groin hernia repair. It is generally recognized that Lichtenstein in 1968 first introduced the plug technique for femoral and recurrent inguinal hernia. The present paper backdates more than 50 years the first application of a plug due to an ingenious Italian surgeon named Davide Fieschi.Plug repair actually represents one of most recommended procedures in open groin hernia repair.

Comment on: mesh erosion into the urinary bladder, rare condition but important to know
No full textWe read with great interest the article “Mesh erosion into urinary bladder, rare condition but important to know” by Li and Cheng [1]. We completely agree with the authors when they conclude that mesh migration or erosion into urinary bladder, even if rarely reported, is a major complication that can occur after both open and laparoscopic inguinal hernia repair in a wide range of latent period. We recently performed a systematic review of all cases of mesh related visceral complications (MRVCs) reported between 1992 and 2018 in literature, identifying 97 events [2]. It was noted that the number of these complications tripled in the last decade (2007–2017), when compared to the previous one (1992–2002). Sigmoid was the most frequently involved organ, with a total number of 40 cases. Mesh erosion or migration into the urinary bladder was the second (31 cases) mesh related visceral complication, collected by frequency. Recurrent urinary tract infection and hematuria represented the most common reported symptoms. Bladder involvement primarily occurred (83%) after preperitoneal inguinal hernia repair with a slight predominance for the laparoscopic approach (21 cases) compared to the open one (15 cases). Less commonly (13%), it followed 3D techniques, probably when the plug was inserted into the transversalis fascia for the treatment of a direct hernia. In seven patients, bladder lesions were associated with bowel involvement (colovesical fistula). In one case, a bladder calculus resulted from bladder erosion following an undetermined herniorraphy. Ureter involvement following mesh-plug and TAPP repair were other anecdotal MRVCs collected in the review

No full textWe have read with great interest the editorial “Mesh in a mess?” by Wexner and
White . We agree with the authors when they say that the potential
complications associated with mesh should not forestall the use of prosthetic
materials when benefits attributable to mesh are demonstrated, as occurs in the
prevention of parastomal hernia. This also applies to groin hernia surgery
Made in Italy for hernia.The Italian history of groin hernia repair
No full textThe history of groin hernia surgery is as long as the history of surgery. For many centuries doctors, anatomists and surgeons have been devoted to this pathology, afflicting the mankind throughout its evolution. Since ancient times the Italian contribution has been very important with many representative personalities. Authors, investigators and pioneers are really well represented. Every period (the classic period, the Middle Age, the Renaissance and the post-Renaissance) opened new perspectives for a better understanding. During the 18th century, more information about groin anatomy, mainly due to Antonio Scarpa, prepared the Bassini revolution. Edoardo Bassini developed the first modern anatomically based hernia repair. This procedure spread worldwide becoming the most performed surgical technique. After World War II synthetic meshes were introduced and a new era has begun for hernia repair, once again with the support of Italian surgeons, first of all Ermanno Trabucco. But Italian contribution extends also to educational, with the first national school for abdominal wall surgery starting in Rome, and to Italian participation and support in international scientific societies. Authors hereby wish to resume this long history highlighting the "made in Italy" for groin hernia surgery
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
