Bowel perforation during insertion of tension-free vaginal tape (TVT)
No full textA 56-year-old non-obese woman with a previous history of pelvic surgery underwent an uneventful TVT procedure for the treatment of genuine stress incontinence. Postoperatively she began to report an acute low abdominal pain and a secondary laparoscopy was performed. The view of the right iliac region showed the tape passing through a loop of the small intestine. The tape was cut in its intraperitoneal portion and the ileum freed and repaired. After the operation the patient recovered well and was discharged on the fifth day after laparoscopy. Despite the section of the tape, 1 year later the patient is objectively cured by the procedure
Sustained prolactin release associated with precocious ovarian failure
No full textFive women after precocious menopause and 1 patient with primary ovarian failure showed a simultaneous elevation of plasma gonadotropin and prolactin. The hypersecretion of plasma prolactin was still present 6 months after ovarian failure. After 12-18 months of observation while FSH and LH concentration remained elevated, prolactin concentrations normalized in 5 women and decreased in 1
Hysterectomy for benign gynecologic disorders - When and why?
No full textCritical examination is needed whenever indications for hysterectomy are difficult to justify. Contrary to what much of current literature seems to suggest, the real problem may not lie in the choice of treatment, but rather in identifying patients for whom conservative treatment is not suitable and who may benefit from surgical intervention. The application of rational diagnostic protocols, use of appropriate medical therapies, and observation of internationally accepted surgical indications could lead to an appreciable reduction in the number of hysterectomies performed worldwide. Nonetheless, this procedure undoubtedly will continue to be a simple and important tool for improving quality of life
A clinical trial on the effects of a combination of elcatonin (carbocalcitonin) and conjugated estrogens on vertebral bone mass in early postmenopausal women
No full textThe study was carried out to determine the effect of a combination regimen of a small dose of calcitonin added to conjugated estrogens with medroxyprogesterone acetate on vertebral bone mass in early postmenopausal women. Comparisons were made with groups of women on calcitonin alone, on conjugated estrogens with medroxyprogesterone acetate alone, or on no treatment. The study was carried out over a 2-year period. The results of the study suggest that the combined regimen of calcitonin and estrogens increased vertebral bone mass in early postmenopausal women to a greater extent than calcitonin alone or estrogen alone. Increases in vertebral bone mass of 11.2% after 1 year and 9.2% after 2 years were demonstrated using the combined regimen. Both estrogens alone and calcitonin alone were, however, very effective in preventing rapid bone loss in the postmenopausal women studied
"Vaginal rejuvenation": comparative effectiveness studies are needed
No full textWe thank Dr. Dietz for his interest (1) in our commentary (2) on female genital cosmetic surgery (FGCS). He maintains that we have mixed up two distinct phenomena: introital cosmetic surgery and "vaginal rejuvenation" procedures. We agree with Dr. Dietz that the reasons for seeking these two types of surgical interventions might substantially differ: the former ones have more evident aesthetic goals and may represent the epiphenomenon of a mental disorder, such as body dysmorphic disorder, whereas "vaginal rejuvenation" procedures are used to treat vaginal laxity and have a functional (rather than aesthetic) objective, that is, sexual pleasure enhancement. However, both surgical procedure types have been defined as FGCS by the Royal College of Obstetricians and Gynecologists (3), and are not medically indicated
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
