[Surgical revision of the lateral nasal wall].
No full textThe purpose of rhinosinus revision through endoscopic surgery is to resolve recurrent, residual pathologies in patients with drug-resistant symptoms and to prevent ocular and endocranial complications. Surgical revision proves quite complex because of the destruction of the anatomical structures. More over the presence of tougher scare tissue which bleeds easily increases the risk of iatrogenous complications. Axial and coronal-projection tomography without contrast medium must be performed prior to surgery. Endonasal orientation is ensured by six main reference points. Three of these points--nasal septum, upper edge of the choana and upper edge of the nasolacrymal duct--are nearly always present while the others may or may not be, depending on what sort surgery has been performed. The present work gives the guidelines for a correct approach to patients who have undergone many previous procedures
Endoscopic limited septoplasty in combination with sinonasal surgery
No full textThe systematic use of fiberoptic techniques in the sinonasal region has made it
possible to assess the nasal septum with more precision. The presence of limited
septal deviation or isolated septal spurs can cause airway obstruction in the
sinuses or impede the execution of endoscopic sinonasal procedures for a disorder
not related to the morphology of the nasal septum. This study assesses the
indications, surgical technique, and results in 170 patients who underwent
endoscopic limited septoplasty performed concomitantly with endoscopic sinonasal
surgery
Apelle e Pigmalione: Leonardo e i "segreti degli antichi"
No full textUn'analisi del rapporto di Leonardo con l'arte e con la cultura degli antichi, a partire dalle fonti contemporanee, dove il nome dell'artista è spesso paragonato a quello di Apelle: vengono quindi esaminati due casi esemplari (la Sala delle Asse nel Castello sforzesco di Milano e i "Diluvi" di Windsor

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
