Modifica della tecnica VQZ per la creazione di uno stoma cateterizzabile e di un neo-ombelico in pazienti con estrofia della vescica
Modified VQZ-Plasty for the Creation of a Catheterizable Stoma Suitable as a Neoumbilicus in Selected Bladder Exstrophy Patients
To present a modified VQZ-plasty technique to create a catheterizable stoma appearing as a normal-looking neoumbilicus that may be used in selected bladder exstrophy (BE) patients. Acatheterizable conduit is created according to the Mitrofanoff principle. An asymmetric V flap, with the base at the level selected as the upper margin of the neoumbilicus, is created and incorporated into the spatulated appendix. Then a Q flap is developed parallel to the shorter margin of the V flap, rotated, and anastomosed to the upper edge of the appendix and to the free margin of the V flap on the contralateral side. The skin gap is filled by a rotational flap overlying the emerging appendix and stoma site. To date the technique has been used in 2 BE patients. After a follow-up of 10 and 6 months, respectively, both have good cosmetic and functional results, with an easily catheterizable stoma. The described technique allows for the creation of a nearly ideal stoma that looks like a normal neoumbilicus in selected BE patients yet without an umbilicus and requiring the placement of a catheterizable condui
Radical soft tissue mobilization and reconstruction (Kelly procedure) for bladder exstrophy repair in males: initial experience with nine cases
Purpose to report the early experience with the Kelly procedure for the treatment of bladder exstrophy (BE) in
males. Materials and methods Nine boys with BE were treated at our institute. One had an untouched BE, four had epispadias after neonatal bladder closure, and four were secondary phalloplasties. Data on surgical complications,
continence status, presence of erections and parental satisfaction with penile appearance and length are reported. Results Mean patient age was 4.7 (1–8.9) years. No intraoperative complications occurred. Two secondary cases experienced formation of a bladder-neck fistula and glans ischemia, respectively. The latter led to glans loss. All the patients had some residual degree of hypospadias after surgery. After a median follow-up of 18.1 (10–22) months, one patient developed chronic bladder outlet obstruction.
Overall, five patients are dry (including two on clear intermittent catheterization and one with a Minz II pouch). The other four are still younger than 3 years, all have spontaneous micturitions and dry interval between 30 and 120 min. Of the eight patients without phalloplasty complications, all had erections, and parents judged the penile length and appearance as being satisfactory in six cases.Conclusion The Kelly procedure is feasible in a vast array of BE patients, but may be formidable, especially in secondary phalloplasties. It allows for complete reconfiguration and lightening of the penis, but exposes to
potentially catastrophic complications, such as partial or complete penile loss. Longer follow-up is needed to assessthe results in terms of continence
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Thoraco-pelvic orthosis: a portable and removable bassinet for secure patient immobilization after primary bladder exstrophy closure
A portable and removable thoraco-pelvic orthosis for patient immobilization after neonatal primary bladder exstrophy closure is described. The device is made of a polyethylene shell, moulded at 170A degrees C, coated inside with a 5 mm pad of plastazote and works applying a constant gentle pressure on the hips
Variations on the Author
“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
Issues with the External and Internal Genitalia in Postpubertal Females Born with Classic Bladder Exstrophy: A Surgical Series
Study Objective: To report our experience with surgical management of gynecological issues in postpubertal female patients born with classic bladder exstrophy (BE). Design: Retrospective review of clinical charts. Setting: Tertiary pediatric urology unit. Participants: 16 postpubertal female BE patients. Interventions: Cosmetic surgery to the external genitalia, widening of vaginal introitus, and treatment of pelvic organ prolapse. Main Outcome Measures: patient satisfaction and additional gynecological problems during follow-up. Results: Eight cases (14-43 years old) underwent cosmetic procedures. All resulted in improved cosmesis, but one case complained of reduced erogenous sensitivity after clitoridoplasty. Five cases (17-20 years old) underwent widening of the vaginal introitus. The modification was as short as possible to avoid any foreshortening of the dorsal vaginal wall. Three cases 33-45 years old presented with pelvic organ prolapse. All were sexually active. One had already given birth. All the three had previously been submitted elsewhere to a posterior vaginal cutback and one to hysterectomy. Two are still awaiting further treatment due to recurrent prolapse. Conclusion: Female BE patients can seek advice to improve the appearance of the external genitalia at any ages. Clidoridoplasty should be considered carefully, because it may harm erogenous sensitivity. Problems with the vaginal introitus typically present at around 20 years of age, probably when BE patients become sexually active. Opening too widely the introitus can cause a foreshortening of the posterior vaginal wall, predisposing to pelvic organ prolapse. Treatment of pelvic organ prolapse is difficult
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
