Diagnostic and therapeutic utility of transrectal ultrasound in urological office prostatic abscess management: a short report from a single urologic center
Objectives: Prostatic abscess (PA) is an infrequent condition in the modern antibiotic era. The everyday use of transrectal ultrasound (TRUS) during diagnostic work-up and the widespread recurrence to prostatic biopsies may lead to an increase of PA diagnosis. In this short report we analyze the patients characteristics and the management of seven recent cases of PA diagnosed in our institution. Materials and methods: The records of 7 patients admitted to our Center for LUTS associated to septic fever or acute urinary retention, was prospectively collected. Suspect of PA was done on digital rectal examination (DRE) and confirmed by TRUS performed after urinary system ultrasound (UUS) evaluation. Patients were admitted to hospital only in case of septic signs. A sovrapubic (SPC) or urethral catheter (UC) was placed depending on symptoms. A TRUS-guided aspiration of PA was performed with patient in lithotomic position, using a 18 gauge two-part needle, side/end fire needle access. Patient was discharged with antibiotic therapy and followed up until complete resolution of the PA and symptoms. Results: Mean age was 62 years (range 24-82). Two patients were diabetics and one was affected by the immunodeficiency acquired syndrome (HIV). In one case, PA was detected after a persistent fever post TRUS guided prostate biopsy. Average prostate volume was 69 ml (range 19-118 ml). DRE was able to diagnose PA only in 2 cases (29%), UUS evaluation in 1 case (14%). All cases were confirmed by TRUS as hypo-anechoic areas with or without internal echoes in all patients. Mean PA dimension was 3.64 cm (range 1.5-8). SPC was placed in 3 cases (43%), UC in 3 patients (43%). Only 1 patient refused catheterization. Side fire needle aspiration was performed in all cases and in combination with end fire access in case of particular location of abscess cavities. Second look was needed in 2 cases (29%). Antibiotics were administered in all cases. The aspirated pus showed a positive culture for Escherichia coli (43%), Klebsiella pneumoniae (29%), Pseudomonas aeruginosa (14%) and Enterococcus faecalis (14%). PA resolution time mean was 9 days (range 3-24). Conclusions: TRUS evaluation in case of persistent LUTS associated with fever or acute urinary retention is determinant in the diagnosis of PA. Office or institutional management with TRUS needle aspiration is a good option in these cases

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
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
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
