Membranous glomerulonephritis and transitional cell carcinoma, improved proteinuria after each tumor resection
No full textNephrotic syndrome has been described in association with solid tumours,
such as carcinoma of the lung or colon, whilst the relationship between
urinary tract cancers and proteinuria is reported less frequently. We
describe a case of a 75-year-old man with nephrotic syndrome and relapsing
transitional cell carcinoma affecting the bladder. Renal biopsy showed
membranous nephropathy. The patient underwent four transurethral tumour
resections and each time we observed improved proteinuria by 3-4 weeks
after surgery. On the contrary, steroid treatment was clearly unrelated to
this improvement. We conclude that, at least in this case, surgical
treatment of the tumour led to improved proteinuria whilst steroid
treatment was not beneficial

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
Ash split cath® in geriatric dialyzed patients
No full textVascular access is the essential step in performing hemodialysis in uremic
patients. In the absence of a permanent and utilizable native
arterio-venous fistula, the use of a tunnelled catheter makes dialysis
therapy possible. The Ash Split Cath, a recently introduced chronic
hemodialysis catheter, was inserted in five patients (7.1 % of our
prevalent dialysis population) because of repeated venous thrombosis in
three patients and a poor venous tree in two. The mean age of patients was
78 years (plus or minus) 7. The average blood flow rate was 250 (plus or
minus) 50 ml/minute and the mean venous pressure 140mm Hg (plus or minus)
35. Recirculation determined by low flux technique was less than 2 %. KT/V
calculated 3 months after the catheter placement was 1.2 (plus or minus)
0.02. During the follow-up we did not document any infection of the exit
site or related to the catheter. This device is simple to place, gives
adequate dialysis treatment and is useful in geriatric dialyzed patients in
whom the arterio-venous fistula can no longer be used
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
Acute renal failure due to a calculus obstructing a transplanted kidney
No full textNephrolithiasis is a rare finding in kidney transplantation and anuria
could be the only clinical sign. We report the case of a 52-year-old
Caucasian male renal transplant recipient admitted due to acute renal
failure (ARF) and anuria. He reported no symptoms and a palpable bulge in
the right iliac fossa corresponding to the graft was present.
Ultrasonography showed hydronephrosis of the graft. A double-J ureteral
stent was inserted with resolution of ARF. ARF with anuria and the presence
of a palpable non-tender, elastic mass over the graft could be the clinical
picture of obstructive ARF in a transplanted kidney
