Is it sensible to perform the operation of Vecchietti laparoscopically?
No full textThe Mayer-Rokitansky-Kuster syndrome is the most frequent cause of vaginal aplasia. There are several operations that can correct this malformation; the most important is that of Vecchietti. The rapid development of the laparoscopic know-how in the last years enables a pelviscopic approach of the laparotomic part of the Vecchietti operation. The question remains whether there are real advantages or whether the choice between laparotomy and laparoscopy should depend exclusively on the personal experience of the surgeon
[Experience with hysteroplasty. Indications, technical references, postoperative and long-term outcome]
No full textThe authors report their experience with hysteroplasty carried out at the gynecological clinic of the University of Verona between 1974 and 1981 and the 10-year follow-up of these patients. Of 46 operated patients, 4 had uterus septus, 38 uterus bicornis (31 bicornis unicollis and 7 bicornis bicollis) and 4 uterus didelphys. The Strassman intervention was used in 32 cases, the Bret-Palmer intervention in 13 and the Jones intervention in 1. The results were very good in 16 cases, satisfactory in 22 and moderate in 8; no negative result has been seen. 38 patients had later a baby. In 4 cases, the uterine malformation was associated with sterility, but this was caused by endometriosis or by pelvic inflammatory disease; therefore, the malformation is not the primary indication for surgery. The best results were achieved in cases of uterus septus or uterus bicornis

[Incidence of genetic alterations in spontaneous abortion. Attempted correlations with beta-HCG values and with the ultrasonic image]
No full textBACKGROUND AND AIMS: The percentage of genetic alterations in spontaneous abortions reported in the literature is between 54% and 76%. The authors felt it was interesting to analyse the frequency of genetic alterations in spontaneous abortions and to establish the correlation between the karyotype and other available data at the time of clinical observation: Beta-HCG values, ultrasonographic imaging, patient's age, parity, week of pregnancy. METHODS: One hundred and twenty samples of trophoblastic tissue taken from spontaneous abortions underwent karyotype analysis. The authors report the correlations between genetic findings and patient age, parity, beta-HCG values, ultrasonographic images and the week of pregnancy. RESULTS: Sixty-two chromosomic anomalies (51.67%) were observed; the other 58 samples (48.33%) were normal. The correlations between chromosome anomalies and the parameters analysed are reported in the other tables and figures. CONCLUSIONS: Neither the ultrasonographic images nor beta-HCG values appear to identify genetic etiology as the cause of spontaneous abortion; this is also true in relation to the week of pregnancy and maternal age. Parity appears to be the sole exception: in this population, spontaneous abortions with a genetic etiology were more frequent in primagravidas compared to other patients. This confirms the fact that hereditary genetic anomalies tend to become evident right from the start of a couple's obstetic histor
Sexuality in the climacterium
No full textThe authors consider 3 important aspects related with the sexual alterations occurring in the climacterium: the variation of the woman's behavior, the conditions influencing this period of life and the possibilities of palliative and/or preventive therapies
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
