Evaluation of the diagnostic accuracy of transvaginal sonography versus hysteroscopy in detection of submucous myomas in peri and postmenopausal women with abnormal uterine bleeding
Get PDFBackground: Abnormal uterine bleeding is a very common gynaecological condition that affects all age groups. This study was aimed at assessing the usefulness of TVS in comparison with hysteroscopy in AUB evaluation. Aim was to evaluate the diagnostic accuracy of transvaginal sonography versus hysteroscopy in detection of submucous myomas in peri and postmenopausal women with abnormal uterine bleeding.Methods: The present study was prospective cross sectional study conducted in the Department of Obstetrics and Gynaecology, Kamla Nehru State Hospital for Mother and Child Indira Gandhi Medical College Shimla for period of one year w.e.f. 1st May 2018 to 30th April 2019. The study was started after hospital ethical committee approval. 76 patients peri and post-menopausal women were enrolled in the study after taking written consent.Results: On TVS- all the study subjects underwent TVS examination, submucous fibroid was detected in 10 subjects (n= 76) i.e. 13.1% (all perimenopausal). On hysteroscopy submucous fibroid was detected in 11 (14.4%) subjects, on histopathology it was confirmed in 11 subjects (14.4%). Out of 11, 8 patients underwent hysterectomy, 1 myomectomy, 2 patients had hysteroscopic removal of fibroid. 1 subject with AUB-LSM was wrongly diagnosed as AUB-P. Sensitivity, specificity, positive and negative predictive values of transvaginal sonography versus hysteroscopy was 90.09%, 100%, 100%, 98.5% respectively.Conclusions: TVS is an important initial modality for evaluating the patient of AUB. It is quick, simple, painless, least invasive, less expensive and readily available procedure and does not need full bladder like TAS. On the other hand, hysteroscopy has a better diagnostic accuracy as it provides the option of see and treat which is recommended for peri and post-menopausal women with AUB
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Huge fibroid uterus mimicking an ovarian malignancy
Get PDFLeiomyoma of the uterus is the most common benign tumor arising from uterine smooth muscle. This is a case of a woman with an exophytic uterine leiomyoma mimicking an ovarian neoplasm. The potential for uterine leiomyomas to grow to an extreme size before causing symptoms is quite remarkable. This is likely due to the relatively large volume of the abdominal cavity, the distensibility of the abdominal wall and the slow growth rate of these tumors. In our case report, despite a fibroid of size reaching up to 34 weeks of gestation, our patient had minimal symptoms except for abdominal discomfort. There were no symptoms related to abnormal uterine bleeding or abnormal bowel or bladder habit. Also, the history and clinical examination of the patient favored a diagnosis of ovarian malignancy
Leptospirosis in pregnancy: a case report
Get PDFLeptospirosis is a leading zoonotic disease worldwide with more than 1 million cases in the general population per year. There is significant mortality due to both delays in diagnosis as well as adequate clinical suspicion. There is also an overlap between the signs, symptoms and biochemical disturbances associated with leptospirosis in pregnancy and the presentation of pregnancy associated conditions, such as pre-eclampsia (PET), acute fatty liver of pregnancy (AFLP) and haemolysis elevated liver enzymes low platelets (HELLP) syndrome. This is a case report of a pregnant woman with leptospirosis who delivered a healthy fetus
