A misleading case of Müllerian anomaly: fibroid degeneration and growth involving nonfunctional, noncommunicating rudimentary horn
No full textObjective: To report a rare, misleading fibroid degeneration involving a nonfunctional, noncommunicating horn in a woman with a unicornuate uterus. Although the presence of a functional rudimentary horn may lead to signs and symptoms that recommend its removal, nonfunctional cases are rarely reported, and because of their apparent functional inactivity, the need for their removal has not yet been reported. No previous report showed the possibility of a degenerative process in a nonfunctional rudimentary horn causing patient discomfort. Design: This is a step-by-step narrated video showing a unique case of fibroid degeneration and growth of a nonfunctional, noncommunicating rudimentary horn in a unicornuate uterus (American Society for Reproductive Medicine classification 2021) and its surgical management. Setting: University academic hospital. Patient(s): A 48-year-old White nulliparous premenopausal woman was referred to our institution because of abdominal pain and an enlarging adnexal mass. Her personal history showed primary infertility with a previous diagnosis of unicornuate uterus. Given the possibility of ectopic ureters in these occurrences, complete computed tomography was performed, and no genitourinary alterations were found. Preoperative imaging (ultrasound evaluation, computed tomography, and magnetic resonance imaging) provided a provisional diagnosis of a suspicious ovarian fibroma. Intervention(s): Considering the patient's age, lack of desire for pregnancy, and volumetric increase in the adnexal mass, a laparoscopic intervention to perform mass removal and prophylactic bilateral salpingectomy was planned. The patient was counseled about the low risk of an underlying malignant transformation. Therefore, the decision to remove the intact mass via a minilaparotomy at the end of the surgery was shared. Once the abdominal cavity was entered, the right unicornuate uterus was found in anatomical continuity with the ipsilateral broad ligament, fallopian tube, and ovary. These structures were wholly attached to the right pelvic wall. On the other side, cranially compared with the right hemiuterus, a roundish myoma-like mass was detected in direct connection with the left broad ligament, fallopian tube, and ovary. In light of a changed intraoperative finding, amputation of the left rudimentary horn and prophylactic bilateral salpingectomy were performed. Main Outcome Measure(s): Showing the fibroid degeneration and growth of a nonfunctional, noncommunicating rudimentary horn in a unicornuate uterus (American Society for Reproductive Medicine classification 2021) treated laparoscopically. Result(s): Laparoscopic removal of the uterine horn was successful, and no intraoperative and postoperative complications occurred. The patient was in good health at the 6-month follow-up visit. The histopathological examination confirmed the fibroid degeneration and absence of the endometrium. Conclusion(s): The lack of symptomatic cases of rudimentary nonfunctional horns reported in the literature led gynecologists to consider them a silent Müllerian anomaly. This unique case demonstrates that even nonfunctional rudimentary horns can undergo symptomatic transformation processes requiring surgery. This information may be helpful for more comprehensive counseling of women and for considering the possibility of this occurrence in the diagnostic workup of misleading Müllerian anomalies. With this in mind, surgical treatment can also be better planned as the technical aspects change compared with what is expected for an adnexal pathology
Conservative treatment of Thoracic Outlet Syndrome – A Review of the Literature
No full textABSTRACT
CONTEXT: Thoracic Outlet Syndrome (TOS) is a debated topic. While there are many clinical studies concerning the efficacy of surgical treatment, there are few regarding conservative treatment. Whether or not conservative treatment is effective and which the best treatment is has not been established yet.
AIMS: (a) To evaluate the efficacy of conservative treatment in TOS with particular reference to physiotherapy, orthotics, and taping; (b) to make general recommendations for conservative treatment.
METHODS: The literature was reviewed. Medical databases consulted: Medline, Embase, CINAHL, Current Awareness, Pedro, Cochrane Library, Medscape. We used the following key words: Thoracic Outlet Syndrome, Double Crush Syndrome, Entrapment, Conservative, Treatment, Rehabilitation, Management. Languages of the articles reviewed: English, French, German, Spanish, Italian, Portuguese.
RESULTS: This analysis focussed on ten studies of conservative treatment and three studies comparing the outcomes of conservative and surgical treatment, published from 1983 to 2001. This review found no randomised controlled trials, systematic reviews, or meta-analyses.
CONCLUSIONS: Conservative treatment seems to be effective in reducing symptoms, improving function, and facilitating return to work, also when compared to surgery. Whether or not conservative treatment is better than no treatment or placebo could not be established, nor could which particular conservative treatment is the best
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
