Effect of the treatment with β-glucan in women with cervical cytologic report of atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (L-SIL)
No full textThe aim of this study was to evaluate the effect of β-glucan in women with ASCUS or L-SIL, as detected by cervical cytologic screening.Aim: The aim of this study was to evaluate the effect of β-glucan in women with ASCUS or L-SIL, as detected by cervical cytologic screening.
Methods: A total of 356 women with ASCUS or L-SIL were enrolled and divided into two groups: 1) 176 patients, treated with topical β-glucan; and 2) 180 patients who were only followed-up. The treatment consisted of two cycles of topical β-glucan applied once a day for 20 consecutive days and treatment separated by ten days. The effect of β-glucan was evaluated comparing Pap cytology results and colposcopic findings between treated patients and controls after 6 and 12 months of follow-up.
Results: After 6 months from enrollment, 63.1% (111/176) of patients treated with β-glucan had a negative Pap smear versus 45% (81/180) of controls (P<0.001), and 43.4% (36/83) of treated patients versus 18.2% (14/77) of controls experienced the disappearance of colposcopic lesions (P=0.001). At the end of the 12-month follow up, 83.5% (147/176) of treated patients versus 60% (108/180) of controls had a negative Pap smear (P<0.001), and 55.4% (46/83) of treated patients versus 24.7% (19/77) of controls experienced the disappearance of colposcopic lesions (P<0.001). No side effects were observed in treated patients.
Conclusion: β-glucan increases the spontaneous regression rate of low-grade cytologic abnormalities as well as cervical findings
Splenic metastasis from cervical cancer: Case report and review of the literature
No full textCervical cancer isolated splenic recurrence is a rare event.We report a case of splenic cervical cancer metastasis treated with salvage surgery 30 months after supralevator anterior pelvic exenteration. In this patient the plasmatic level of squamous cell carcinoma antigen increased in the absence of any evidence of disease at the instrumental examination 24 months after surgery. Surgery had a high impact on quality of life
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
Multiple Bulky Lymph Nodal Metastasis in Microinvasive Cervical Cancer: A Case Report and Literature Review.
Full text linkMicroinvasive squamous cell cervival carcinoma is characterized by an exceptional incidence of lymph nodal metastasis. We report the case of a 45-year-old woman affected by IA1 squamous cell carcinoma, found to have massive pelvic lymph nodal metastasis. After a systematic pelvic and aortic selective lymphadenectomy, at 16 months of follow-up, she is still disease-free. Patients suitable for conservative therapy should be carefully counselled about the established risks and benefits of nondestructive treatment options
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
Reactive lymphoid hyperplasia of liver mimicking late ovarian cancer recurrence: case report and literature review.
No full textReactive lymphoid hyperplasia (RLH) is a rare, benign, lymphocytic tumour-like lesion reported in various organs. It has been previously identified in 18 cases in the English-language literature, but only 5 of them were related to oncological disease. No previous cases have been described of RLH occurring in ovarian cancer patients. We describe a case of hepatic RLH which developed in a patient treated for ovarian cancer 11 years previously. Radiological features on computed tomography (CT) scan and PET-CT (positron emission tomography-computed tomography) were strongly suggestive of oncological disease, in contrast to magnetic resonance imaging (MRI); the volume increment of the nodular lesion and the rise in carbohydrate antigen 125 corroborated the hypothesis of malignancy. The patient was subjected to resection of the 7th segment of the liver and the final histological report showed RLH. RLH should be considered in the presence of hepatic lesions in suspected ovarian cancer recurrence. Imaging techniques should be thoroughly investigated to exclude tumor recurrence promptly, in order to avoid unnecessary surgery
