Electro-cautery of myomas during caesarean section – two cases reports
Myomectomy is a surgical procedure not usually performed during caesarean section because associated with high risk of haemorrhage and other complications. The goal of our study is to evaluate the feasibility of myomectomy during caesarean section, the outcome, and try to establish the favourable conditions to perform a myomectomy during the same surgical event. Electro-cautery of intramural-subserous myomas was performed on two different patients. Only the myomas of little or middle size were treated. Both patients had multiple fibroids, a firm contraindication for myomectomy during caesarean section. After 10 and 13 months since myoma electro-cautery, all uterine fibroids treated were completely reabsorbed. These preliminary results regard the fibroids of middle size. It could be interesting evaluating the electro-cautery on bigger fibroid
Ovarian fibrosarcoma: case report and latest trends in diagnostic and therapeutic management
The authors describe a rare case of primary ovarian fibrosarcoma and the latest trends in diagnosis and therapy. The rarity of this dis-ease and the scarce number of reported cases pose serious problems in differentiating it from other fibrous forms. A 58-year-old woman presented intermittent pelvic pain and a demarcated, mobile, and solid lump in the right adnexa. Diagnostic imaging revealed a solid- cystic inhomogeneous mass occupying the right adnexa and the CA125 level was elevated. The patient underwent total hysterectomy with bilateral salpingo-oophorectomy and infracolic omentectomy. Histological findings with immunomarkers led to the final diagnosis of low-grade malignant mesenchymal neoplasm derived from the ovarian stroma compatible with fibrosarcoma. Twenty-four months follow-up showed no recurrence of disease. Ovarian fibrosarcoma is very uncommon neoplasm with a poor prognosis. Despite the efforts of several authors in reporting morphological, histological, and immunohistochemical features of this neoplasm, nowadays, the diagnosis, treatment, and prognosis are unresolved issues. The present case highlights the important role of immunohistochemistry to define histological type and differential diagnosis. As demonstrated by the authors' experience, they believe that surgery is curative in the early stages with low immunohistochemical positivity for ki67 and that chemotherapy should be reserved in advanced stages with regimens in use for the treatment of sarcomas
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Outcomes of monopolar versus bipolar endometrial ablation on uterine bleeding and psychophysical wellbeing
BACKGROUND: To compare outcomes of endometrial ablation with monopolar versus bipolar resection on uterine bleeding and psychophysical wellbeing.METHODS: In a prospective randomized study, 100 perimenopausal patients, without desire of pregnancy and with no response to pharmacological treatment, underwent endometrial ablation from 2012 to 2014. They were randomly divided in two groups: 50 patients treated with monopolar electrode resection loop (group A) and 50 patients treated with bipolar electrode resection loop (group B). Operative parameters were immediately assessed. Menstrual outcome parameters and psycho-physical well-being parameters were evaluated after 12 months.RESULTS: No significant difference in operating time was recorded between the two groups. No serious hysteroscopic complication occurred with a similar immediate cumulative complication rate but two cases of intravasation were recorded in group A. The late cumulative complication rate was higher in group A than group B (44% vs. 24%). Cycle was overall controlled in over the 80% of the cases in the two groups without significant difference. The analysis of Short Form-36 showed an improvement of all assessed items after the endometrial ablation without significant difference.CONCLUSION: Hysteroscopic endometrial ablation performed with bipolar loop electrode is as effective as resectoscopy with unipolar loop electrode regarding menstrual and psychophysical wellbeing outcomes. Endometrial ablation with bipolar electrode loop is safer but more expansive than monopolar electrode loop
Variations on the Author
“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
We 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
We 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
We 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
