Pelvic floor rehabilitation for continence recovery after radical prostatectomy: Role of a personal training re-educational program
No full textPurpose: radical prostatectomy (RP) is affected by urinary incontinence (UI) that, even if temporary, can severely impact patients quality of life. We investigated if a post surgery tutored and personal trained pelvic floor re-educational program improves continence recovery more than pelvic floor exercises performed by patients on their own. Patients and Methods: 332 incontinent (>1 pad/daily) patients (pts) submitted to RP between 2006 and 2008 were prospectively randomized in group A (166 pts) and group B (166 pts). The first group performed an intensive tutored pelvic training program and the second formed the control group. The follow-up was at one year and the self report of recovery of continence was measured every 3, 6 and 12 months. Results: the median time of continence recovery in group A was 44±2 days, while in group B it was 76±4 days. Patients enrolled in the pelvic floor re-educational dedicated program (group A) achieved continence earlier than the control group (group B). In fact, the number of incontinent patients at the different follow-up intervals was higher for the control group than for the treatment group. Conclusion: We have demonstrated that a post RP personal training program of pelvic muscle re-education supported by a physician and nurses expert in continence disorders have a benefit in future continence
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
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
Rare perinephric myxoid pseudotumor of fat causing ureteropelvic junction obstruction: a case report
No full textUreteropelvic junction obstruction (UPJO) is a congenital or acquired functionally significant impairment of urinary transport from the renal pelvis to the ureter. Congenital UPJO typically results from intrinsic disease such as the presence of an aperistaltic segment of the ureter, aberrant vessels or kidney abnormalities. Rare conditions can sometimes mimic an UPJO. We present a case of an 86-year-old woman with a UPJO diagnosed on CT. The patient was counseled on treatment options and elected to undergo a left uretherorenoscopy (URS) plus left laparoscopic pyeloplasty. The definitive histopathologic diagnosis was perinephric myxoid pseudotumor of fat, an extremely rare neoplasm, mass-forming. To the best of our knowledge, this is the first known case of a pseudotumor of fat causing UPJO. 6-month follow-up showed neither recurrence nor residual UPJO. We describe a rare presentation of extrinsic perinephric myxoid pseudotumor of fat causing UPJ obstruction. In elderly patients with no history of malignancy, UPJ obstruction can occur because of atypical masses
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
Preoperative variables predicting pelvic lymphnodes involvement. Is lymph nodes dissection still a must before radical prostatectomy?
No full text32 patients with confined (localized) prostate cancer histologically confirmed have been included in a retrospective study, 16 patients underwent laparoscopic staging lymphadenectomy, meanwhile another group of 16 patients had a lymphadenectomy as a part of radical sovrapubic prostatectomy. 25% of laparoscopic lymphadenectomy patients were N+ and subsequently have been treated with hormonotherapy. The whole cohort was analysed without division based on type of lymphadenectomy procedure. The patients were stratified as: a) Clinical stage by DR, and TRUS and biopsy; b) Grade: (1) low grade Ml, (2) medium grade III-IV (3) high grade; c) PSA score: (1) PSA10 20 ng/ml. Taking the pathologic stage as dependent variable factor and all other data as independent variable factors a statistic analysis was carried out aiming to predict the progression at the pathologic stage as dependent factor. Clinical stage: 77% of stage T l c- T2a-b patients had localised disease but only 24% of stages T2c and T3a were prostatic confined diseases. 24% of T2c and 21 % of T3a were N+. PSA: 64% with PSA below 10 ng/ml had intracapsular neoplasm and 40% with PSA higher than 20 mg/ml had been N+. Primary Gleason grade: 55.7% of low grade neoplasm were intracapsular, 74.4% of high grade were extracapsular with 45% of N+. A discriminant analysis was first performed on three group: 1) intracapsular, 2) extracapsular (locally advanced), 3) with lymphnodes metastasis. Lymphnode invasion was predictable in 63% of cases. The discriminant analysis correctly divide the subject with low stage from the restant with locally advanced disease and from those with lymphnode metastases but it does not allow to separate locally advanced disease bearers from patients with lymphnodes invasion. This is probably due to the fact that often locally advanced tumour and lymphnode invasion cosiest. The logistic regression identifies the association of Psa (p=0.000), clinical stage (p=0.001) and primary Gleason grade as valuable factors in predicting pathological stage (75%). Only the patients with organ confined prostate cancer can benefit from radical prostatectomy. The best problem is not to identify node positive disease, often associated with extracapsular disease but to select prior the surgery the patients with a potentially extracapsular extension of the cancer
Identification of prostate cancer risk categories according to surgical margins status, pathological stage and Gleason score
No full textDispelling 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
