ECHOCARDIOGRAPHIC ASSESSMENT OF 537 DOGS WITH MITRAL VALVE PROLAPSE AND LEAFLET INVOLVEMENT

2009

In this work we investigated which mitral valve leaflet was most often involved in mitral valve prolapse with degenerative mitral valve disease and whether there was an association with breed, age, gender, or weight. Five hundred and thirty-seven dogs with mitral valve prolapse-degenerative mitral valve disease were assessed; the cross-breed dog was the most represented breed (248 dogs, 46.2%). Mitral valve prolapse was more common in male dogs, and the average age was 11.3 +/- 2.8 years. Prolapse of the anterior leaflet was present in 48.4% of dogs, prolapse of the the posterior leaflet in 7.1%, and bileaflet prolapse was present in 44.5%; this distribution is different than that typically…

Trocar-related abdominal wall bleeding in 200 patients after laparoscopic cholecistectomy: Personal experience

2006

AIM: To determine the complications and incidence of the first and second access-related vascular injuries induced by videolaparoscopic cholecistectomy. METHODS: We retrospectively reviewed vascular injuries in 200 consecutive patients who underwent videolaparoscopic cholecistectomy from 2003 to 2005. One hundred and one patients with placement of radial expanding trocars were assigned into group A and 99 patients with placement of pyramidal tipped trocars into group B. All the patients were submitted to open access according to Hasson for the first trocar. RESULTS: Bleeding did not occur at the intraoperative cannula-site in group A. However, it occurred at the intraoperative cannula-site …

Three-Year Results of Repaired Barlow Mitral Valves via Right Minithoracotomy versus Median Sternotomy in a Randomized Trial

2012

<b><i>Objectives:</i></b> To clarify whether the results of repair of a complex mitral lesion (Barlow valve) at the intermediate-term follow-up are independent of the mode of surgical access [minithoracotomy vs. median sternotomy (MS)]. <b><i>Methods:</i></b> In a prospective randomized study of mitral repair for Barlow disease using either a minimally invasive (MI) approach or MS, we achieved an average follow-up of 3 years (echocardiography, physical examination and quality of life). Mitral repair was achieved with polytetrafluoroethylene chordal implantation for both leaflets. <b><i>Results:</i></b> Both groups inclu…

Miti mediterranei: un viaggio millenario

2020

Ha osservato Sebastiano Tusa: «Al di là delle immense e svariate risorse materiali che il mare ha offerto ed offre all’uomo, ve ne sono altre che attengono alla sfera sovrastrutturale che hanno nei millenni rifornito ed animato l’immensa enciclopedia dei miti, delle leggende e dei culti ad esso ispirati o, comunque, connessi». Distesa senza confini e abisso insondabile, il mare, con le sue repentine mutazioni di stato, le sue furiose tempeste e le sue mortifere bonacce, si è sempre imposto a chi lo solcava per raggiungere altri luoghi o per ricavarne da vivere come spazio del pericolo e del mistero, generando e sostenendo un ampio e polimorfo immaginario e divenendo attore e scenario al con…

Une nouvelle approche mixte d'enrichissement de dimensions dans un schéma multidimensionnel en constellation Application à la biodiversité des oiseaux

2015

International audience; Les entrepôts de données (DW) et les systèmes OLAP sont des technologies d'analyse en ligne pour de grands volumes de données, basés sur les be-soins des utilisateurs. Leur succès dépend essentiellement de la phase de conception où les exigences fonctionnelles sont confrontées aux sources de données (méthodologie de conception mixte). Cependant, les méthodes de conception existantes semblent parfois inefficaces, lorsque les décideurs définissent des exi-gences fonctionnelles qui ne peuvent être déduites à partir des sources de don-nées (approche centrée sur les données), ou lorsque le décideur n'a pas intégré tous ces besoins durant la phase de conception (approche c…

Dimension enrichment with factual data during the design of multidimensional models: application to bird biodiversity

2015

20 pages; International audience; Data warehouses (DW) and OLAP systems are technologies allowing the on-line analysis of huge volume of data according to decision-makers’ needs. Designing DW involves taking into account functional requirements and data sources (mixed design methodology) [1]. But, for complex applications, existing automatic design methodologies seem inefficient. In some cases, decision-makers need querying, as a dimension, data which have been defined as facts by actual automatic mixed approachs. Therefore, in this paper, we offer a new mixed refinement methodology relevant to constellation multidimensional schema. The proposed methodolgy allows to decision-makers to enric…

Semi-automatic conception and implementation of data warehouses : application to ecological data

2015

This thesis concerns the semi-automatic design of data warehouses and the associated OLAP cubes analyzing ecological data.The biological sciences, including ecology and agronomy, generate data that require an important collection effort: several years are often required to obtain a complete data set. Moreover, objects and phenomena studied by these sciences are complex and require many parameter recording to be understood. Finally, the collection of complex data over a long time results in an increased risk of inconsistency. Thus, these sciences generate numerous and heterogeneous data, which can be inconsistent. It is interesting to offer to scientists, who work in life sciences, informati…
