Gasless laparoscopic myomectomy - Indications, surgical technique and advantages of a new procedure for removing uterine leiomyomas
No full textOBJECTIVE: To evaluate the feasibility, safety and reliability of gasless laparoscopic myomectomy (GLM) using a new subcutaneous lifting system (Laparotenser, Lucini L & T, Milan, Italy) for removing subserosal and intramural leiomyomas. STUDY DESIGN: A total of 279 women with at least 1 symptomatic subserosal or intramural myoma measuring >30 mm underwent GLM between April 1997 and July 2001. All procedures were performed by the same surgeons using the same technique. RESULTS: GLM was successful in all 279 patients. The mean size of the myomas were 5.9 cm. Their average number per patient was 3.1. The mean operating time was 73 minutes. Forty-eight patients subsequently carried a pregnancy to term. No cases of uterine rupture during pregnancy or labor were observed. CONCLUSION: GLM is a feasible, reliable and safe procedure for removing intramural and subserosal myomas. It appears to offer several advantages over laparoscopy with pneumoperitoneum. In addition, the largest and multiple medium-sized myomas can be removed rapidly and safely
Isobaric (gasless) laparoscopic myomectomy during pregnancy
No full textWe report on the first case of an isobaric (gasless) laparoscopic myomectomy during the second trimester of pregnancy. Our patient had acute abdominal pain that did not respond to medical management. The procedure was performed under spinal anesthesia with conscious sedation. The remainder of the pregnancy was unremarkable. We believe that Surgical management of uterine leiomyoma during pregnancy may be successfully performed in carefully selected patients. Laparotomy can be avoided, and pregnant patients can be managed safely by operative laparoscopy. With isobaric laparoscopy, the adverse effects and potential risks of CO, insufflation are eliminated. The procedure can be performed under loco-regional anesthesia. The uterine closure can be performed safely and quickly as in laparotomy. (c) 2005 AAGL. All rights reserved

Rilievo e documentazione dei beni culturali: gli Scavi di Ercolano
No full textDa alcuni anni il DISTART – Dipartimento di Ingegneria delle Strutture, dei Trasporti, delle Acque, del Rilevamento, del Territorio – dell’Università di Bologna, sta operando nel settore del rilevamento sul sito archeologico di Ercolano; l’impegno fa seguito ad un ampio spettro di attività effettuate negli anni passati a Pompei, in particolare sull’Insula del Centenario e su alcuni ninfei significativi della città2. La ricerca si inquadra nell’ambito del progetto DHER e dell’accordo tra l’Università di Bologna e la Soprintendenza Archeologica di Pompei Ercolano e Stabia3. Alcuni elementi campione di particolare interesse scientifico sono stati
oggetto di interventi articolati in vari livelli, a differente scala, condotti in modo integrato tra loro, ricorrendo a tecniche e metodologie diverse: sul sito di Ercolano l’attenzione si è di recente concentrata sulla Casa del Tramezzo di Legno e sulla Casa
dello Scheletro, appartenenti all’Insula III e sulla Casa di Nettuno ed Anfitrite nell’Insula V (Fig. 1). Le attività hanno avuto luogo a partire dalla campagna del marzo 2006 e di seguito vengono evidenziati gli studi effettuati ed i primi risultati ottenuti, classificati su differenti scale di analisi
Use of historical images for the documentation and the metrical study of Cultural Heritage by means of digital photogrammetric techniques
No full textThe paper is related to a multi-disciplinary project started in 1999, within a collaboration established between the University of Bologna and the Archaeological Superintendence of Pompeii. In the frame of this project was activated a rigorous survey, by the integration of different geomatic techniques (GPS, Laser Scanning, Photogrammetry, Visual Reality), of the most significant nymphaea of Ercolano and Pompeii (Naples); these are elements of remarkable archaeological and artistic value and presenting various geometric characteristics, needing a very accurate description of the decorative apparatus, often entrusted to particularly complex and rich mosaics.
In particular are here described the studies conducted about the Lararium from the “House of the Skeleton” in Ercolano.
This object is interesting for this kind of study because it presents some static problems and it has suffered during the excavations many interventions and changes, until the complete disassembly and successive replacement in situ.
Three images of the 1927-1928 periods were chosen with the aim of creating a historical 3D model of the object, comparable with the actual model, derived by the photogrammetric survey conducted in the 2006 campaign.
After an experimentation phase necessary to define the most suitable methods to perform the images calibration (single or multi photo, with the use of geometric constraints or also with the use of control points), a valid set of parameters was found and a complete model of the object was reconstructed, representive of the metric and qualitative conditions in this epoch.
The dimensional comparison between the two temporal situations (historical and actual) has also permitted qualitative and quantitative considerations about the differences, offering a very important tool for the evaluation of the past restorations and useful also to plan all the future interventions
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
