Eosinophilic cystitis: description of two cases and literature review.
No full textEosinophilic cystitis is a rare inflammatory disease of the bladder of unknown etiology and immunologic pathogenesis. We report two cases of eosinophilic cystitis recently observed in adult male patients with negative history for allergic disease and absence of peripheral eosinophilia. The clinical and radiological picture of the illness is not specific and the diagnosis is exclusively histological. In cases which are less severe and of recent origin medical treatment with steroids, antihistamines and/or nonsteroidal antiinflammatory drugs is indicated. However, the most serious and long-standing cases usually require endoscopic or surgical treatment. The endoscopic fulguration of the areas of bladder mucosa affected by eosinophilic cystitis was effective in both our cases
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
Polyorchidism: 2 case reports
No full textPolyorchidism is a rare anomaly with approximately 70 cases reported in
literature. The exact explanation for the production of polyorchidism is not
known, although several theories have been proposed, including anomalous
appropriation of cells, initial longitudinal duplication of the genital ridge and
transverse division of the genital ridge, either through some local accident of
development of peritoneal bands. A functional classification based upon the
embryogenic development is provided. Type I: the supernumerary testis lacks an
epididymis and vas. The split-off part of the primordial gonad does not
communicate with the mesonephric tubules from which the epididymis develops. Type
II: the supernumerary testis is linked to the regular testis by a common
epididymis and shares a common vas with it. The division of the genital ridge
occurs in the region where the primordial gonads are attached to the mesonephric
ducts, although the latter are not divided (incomplete division). Type III: the
supernumerary testis has its own epididymis but shares the vas with the regular
testis. This variant results from a complete transverse division of the genital
ridge. In the majority of the reported cases, the patients are asymptomatic and
have painless groin or testicular masses. Approximately 50% occur as maldescent
or cryptorchidism, and about 30% are associated with indirect hernia. The
remaining 20% are discovered variously in relation to torsion, or are associated
with hydrocele, epididymitis, varicocele or infertility. Moreover, since there is
a 20 to 40 fold increase in testicular malignancy in patients with cryptorchidism
compared with the normal testis, tumours of the supernumerary testicles are not
unusual. We reported two cases of polyorchidism: the first patient is probably a
longitudinal division of the genital ridge and the second is a completely
duplication of the primordial gonads. The patients described vague, intermittent,
testicular pain. Physical examination and the scrotal sonography and magnetic
resonance revealed in the first patient a supernumerary testis in the right
scrotal space and in the second a bilateral double testis. In conclusion we think
that in the absence of any concomitant disorder and if testicular tumor can be
ruled out by ultrasonography and magnetic resonance imaging, surgical exploration
with biopsy is unnecessary
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
