Surgical management of penile amputation in children
No full textAbstract Purpose: Penile amputation in children is rare. If the amputated organ cannot be salvaged, standard treatment options include sex reassignment or creation of a penoid with a musculocutaneous flap. We describe our experience with phallic reconstruction after amputation. Methods: Between 2005 and 2007, we observed 3 patients with penile amputation. All presented a flat pubic scar and a severe urethral stricture for which urinary diversion had been performed in two.The first step of the procedure was penile augmentation. The latter included dissection and advancement of the residual erectile tissue by either division of the suspensory ligament (n = 2) or detachment of the corpora cavernosafromthepubicbones.Then,meataladvancementwasattemptedandcombinedwithastagedoral mucosa urethroplasty, if necessary. Finally, skin coverage was achieved using local flaps (n = 2) or a free graft harvested from the inguinal region. In 2 patients, a pseudoglans was sculptured from the pubic scar. Results: Innocasetheprocedurecouldbeperformedinasinglestage.Inonepatient,2additionalcosmetic revisions wererequired.Goodpenileaugmentationwasachievedinallthe3cases.Allpatientspresentedat least nocturnal erections and reported to be satisfied with the cosmetic results. Conclusions: Our experience suggests that an attempt to phallic reconstruction by retrieval of any residual erectile tissue might be worthwhile before embarking on a penile replacement. In a few cases, this may allow recreation of a penis with good cosmesis and functio

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
Scintigraphic renal function after unilateral pyeloplasty in children: a systematic review
No full textOBJECTIVE
To systematically review previous reportsand thus determine the functional outcome after pyeloplasty in children with unilateral hydronephrosis due to pelvi-ureteric junction obstruction, and the possible
variables that could affect it. Methods we searched medline/pubmed, embase,and web of science for articles in english published from 1966 to 2007, using both‘medical subject headings’ and ‘free text’
protocols. Abstracts, full texts, and bibliographies of pertinent papers werere viewed to select studies of scintigraphic renal function before and after pyeloplasty. The postoperative change in scintigraphic
renal function was assessed in relation to presentation (antenatal vs postnatal), timingof surgery (early vs delayed), age at surgery, and preoperative ultrasonography (US) andscintigraphic findings.
Results: thirty-six studies (2.1% of the initial search)were eventually selected for review. Studies were generally of poor scientific quality andvery heterogeneous in their indications for surgery and follow-up protocols. Postoperative function showed a wide variability. Symptomatic patients diagnosed
postnatally seemed to have a greater chance of functional improvement after surgery than asymptomatic patients diagnosed antenatally. The chance of improvement seemed also to be greater in patients with
moderately rather than severely impaired preoperative function. Otherwise, the improvement seemed unrelated to the age at surgery, the preoperative US findings, or thexcretion pattern on renal scintigraphy. Of patients having delayed surgery >97.5% had preserved function afterward. Conclusion patients with moderately impaired preoperative function and those diagnosed postnatally because of symptoms are those with the greatest likelihood of having a functional improvement after surgery
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
