Laparoscopic pelvic and paraaortic lymphadenectomy in gynecologic oncology.
No full textIn the early 1990s, different authors independently developed techniques for
pelvic and paraaortic lymph node sampling. Since then, laparoscopic
lymphadenectomy has been demonstrated to yield the same number of nodes when
compared with the laparotomic approach. Only one microscopically involved lymph
node was lost at laparoscopic lymphadenectomy when a laparotomic control followed
immediately after. It seems bleeding, which is the most serious perioperative
complication, is more common during laparoscopic lymphadenectomy than during
laparotomy; however, the incidence will decrease with experience of the surgeon.
The laparoscopic procedure does not seem to influence negatively the survival of
patients with early stage endometrial and cervical cancer. There does not seem to
be a significant reduction in overall hospital charges for laparoscopic surgery
in oncology, but patients who undergo laparoscopic surgery recover significantly
sooner than those who undergo laparotomy
Extensive fever workup produces low yield in determining infectious etiology.
No full textOBJECTIVE: The study was undertaken to evaluate the use of a fever workup in
women undergoing benign gynecologic procedures.
STUDY DESIGN: A retrospective chart review was performed at Jackson Memorial
Hospital between 1994 and 2000. Information was abstracted from hospital and
clinic records. Fever criteria was defined as 1 temperature equal to or greater
than 101.5, or 2 equal to or greater than 100.4, at least 4 hours apart within a
24-hour period. Patients undergoing additional intraoperative procedures leading
to increased febrile morbidity were excluded. Data abstracted included patient
demographics, procedure, complications, antibiotic use, and extent of fever
workup. Statistical analysis used was 2-sample t tests, Wilcoxon rank test, chi2
test, and multivariate logistic regression. Alpha level = .05.
RESULTS: The charts of 505 patients were reviewed, and 147 patients met fever
criteria. All patients underwent surgery for benign conditions, abdominal
hysterectomy being the most common (90%). The study population was divided into 2
groups: the noninfectious group and infectious group. These groups were
determined by wound infection, pelvic abscess, blood or urine culture,
ultrasound, and chest roentgen. Both groups were found to be similar with respect
to demographics, surgical procedures, and postoperative complications, with the
exception of body mass index (28.4 vs 31.7) and length of hospital stay (3.9 vs
5.3). Results from fever workups included positive results blood cultures (9.7%),
urine culture (18.8%), and chest roentgens (14%) in this study population. We
found no association between positive urine analysis and urine culture. When
comparing both groups, a statistically significant difference was found with
regard to maximum temperature elevation, number of days febrile, and
postoperative day of maximum temperature (P < .05).
CONCLUSION: The extensive fever workup was not frequently positive in this study
population. Its use and cost-effectiveness should be questioned. Therefore, the
fever workup should be tailored to the individual patient
Uterine sarcoma occurring in a premenopausal patient after uterine arteryembolization: a case report and review of the literature.
No full textObjective: We report a case of uterine leiomyosarcoma occurring after uterine artery embolization and review the previously published cases. We estimate the incidence of sarcoma after UAE, the mean diagnostic delay in young women undergoing this procedure and review the potential and limits of preoperative procedures in diagnosing uterine sarcomas. Case report: A 35-year-old woman had an early failure after UAE. She underwent surgery 13 months after the procedure. Final pathologic report was consistent with uterine leiomyosarcoma. Conclusion: Incidence of uterine sarcomas after UAE is low, probably similar to that of misdiagnosed leiomyosarcomas in women undergoing surgery for presumed symptomatic leiomyomas. Therefore a relation between the procedure and the malignancy seems to be very unlikely. Diagnostic delay in menstruated women younger than 50 undergoing UAE for presumed symptomatic leiomyoma ranges between 13 and 15 months. The safest procedure for women who fail the conservative management of leiomyoma with UAE is surgical, allowing for definitive pathologic exclusion of malignancy
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
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
