Urinary tract infection in the newborn and the infant: state of the art
Get PDFUrinary tract infection is one of the most common causes of infection in newborns. Obtaining a urinary tract infections (UTIs) diagnosis just on the basis of the clinical findings is frequently difficult, however, being the pediatrician's goal to reduce the risk of renal scarring, a prompt diagnosis and treatment is of extreme importance. The key instrument for the diagnosis of UTIs is represented today by urine culture. However, in reality, the caregivers and investigators are increasingly demanding fast and cheap methods for a rapid and effective diagnosis

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Early-onset basal cell carcinoma in a case of Ivemark syndrome
No full textFirst described by the Swedish paediatrician, Björn Ivemark,
(1925-2005), IS is a rare congenital heterotaxic disorder
with lateralization anomalies [1]. It accounts for 1-
3% of all congenital heart defects, with an incidence of
1 in 10-20,000 live births. To date, about 200 cases
have been reported in the literature, mostly sporadic, but
familial occurrence has also been described, suggesting
autosomal recessive inheritance, with a male preponderance
A Case of Pyoderma Gangrenosum After Long Saphenous Vein Harvesting
No full textIntroduction: Pyoderma gangrenosum is a rare cause of ulceration that may be confused with post-operative wound infection. Report: A 74-year-old man presented with a painful ulcer after long saphenous vein harvesting. On examination, a 7×5cm ulcer was noted overlying the distal end of the wound. The ulcer had a patchy necrotic base and well-demarcated violet edges with surrounding erythematous, indurated skin. Review of the clinical history revealed previous delayed wound healing. The diagnosis of pyoderma gangrenosum was confirmed by histological analysis. Discussion: This case highlights the importance of the pre-operative medical history in identifying patients at risk of pyoderma gangrenosum. © 2013 European Society for Vascular Surgery
