USO DELLA PROTESI INTRAPERITONEALE IN PTFE IN UN GRANDE LAPAROCELE DOPO TRAPIANTO RENALE : CASE REPORT
2008
Introduzione Il caso riguarda il trattamento chirurgico con l’utilizzo di protesi intraperitoneale dual mash PTFE di un laparocele in un paziente di 55 aa sottoposto a precedente trapianto di rene. Tale complicanza derivava da un urinoma per la necrosi massiva dell’uretrere distale del graft; per cui il pz. è stato sottoposto a reintervento in 2 giornata post trapianto con ricostruzione del piano del muscolo aponeurotico. A circa un mese dal trapianto comparsa di tumefazione in sede incisionale, che rapidamente si è evoluta fino a raggiungere le caratteristiche del grande laparocele.Gli esami strumentali evidenziavano la presenza dell’omento e del piccolo intestino nel sacco erniario. Mater…

Maculopapular rash and fever: a diagnostic challenge to the paediatrician in the COVID-19 pandemic
2021
Introduction: Several clinical conditions can manifest with fever and a maculopapular rash in paediatric age. Although some presentations are benign, others may be medical emergencies, which demand a prompt diagnosis and treatment. Some of the more common causes of fever and maculopapular rash include infectious diseases (Sars-CoV-2, Parvovirus B19; Coxsackie; Epstein-Barr virus infection, Mycoplasma Pneumoniae, etc), hypersensitivity reactions, Autoinflammatory syndromes, vasculitis, Kawasaki disease (KD), autoimmune diseases. Objectives: In the COVID-19 pandemic era these symptoms need a well-organized hospital strategy to rapidly exclude Sars-CoV-2 infection and to distinguish severe and…
SELENIUM AND AUTOIMMUNE THYROIDITIS
2023
Selenium (Se) is an essential trace element of pivotal importance to human health. Se is incorporated into selenoproteins (SePs) which have pleiotropic effects, including antioxidant and anti-inflammatory effects, and in the production of active thyroid hormone. These findings may explain the relationship between Se deficiency and pathogenesis of various human diseases including thyroid disorder. In line with these observations, the therapeutic effectiveness of Se supplementation has already been reported in patients with various thyroid diseases. However, there are still controversial data about the optimal dose of Se to be administered, as well as the duration and efficacy of treatment an…
Conclusioni

La macroecomia della finanza ha ridotto i vincoli di libertà delle nazioni in assenza di una codificazione delle regole condivise da tutti i partecipanti al sistema economico internazionale. La dimensione spaziale della crescita, invece, è probabilmente una risposta adatta ai processi di cambiamento in atto e complementare alle risposte fino ad oggi fornite. La marginalità per lo sviluppo regionale, ovvero l’ampia utilizzazione di giacimenti economici, individuali, innovativi poco esplorati, assume un valore strategico perché rivaluta, nell’ambito dei processi di cambiamento economico, l’importanza dei contesti regionali e locali nei loro diversi ambiti. sfida e una scelta per il cambiament…
Shock formation in the dispersionless Kadomtsev-Petviashvili equation
2016
The dispersionless Kadomtsev-Petviashvili (dKP) equation $(u_t+uu_x)_x=u_{yy}$ is one of the simplest nonlinear wave equations describing two-dimensional shocks. To solve the dKP equation we use a coordinate transformation inspired by the method of characteristics for the one-dimensional Hopf equation $u_t+uu_x=0$. We show numerically that the solutions to the transformed equation do not develop shocks. This permits us to extend the dKP solution as the graph of a multivalued function beyond the critical time when the gradients blow up. This overturned solution is multivalued in a lip shape region in the $(x,y)$ plane, where the solution of the dKP equation exists in a weak sense only, and a…
Numerical study of the Kadomtsev–Petviashvili equation and dispersive shock waves
2018
A detailed numerical study of the long time behaviour of dispersive shock waves in solutions to the Kadomtsev-Petviashvili (KP) I equation is presented. It is shown that modulated lump solutions emerge from the dispersive shock waves. For the description of dispersive shock waves, Whitham modulation equations for KP are obtained. It is shown that the modulation equations near the soliton line are hyperbolic for the KPII equation while they are elliptic for the KPI equation leading to a focusing effect and the formation of lumps. Such a behaviour is similar to the appearance of breathers for the focusing nonlinear Schrodinger equation in the semiclassical limit.
3-Dimensional Hydrodynamic Interaction of a Supernova Remnant Shock with an Isolated Cloud
2006
We report on a computational key-project in astrophysics. The project is aimed at studying the interaction of a supernova shock wave with interstellar clouds. We describe the numerical code used, namely FLASH, a multi-dimensional astrophysical hydrodynamics code for parallel computers developed at the FLASH center (The University of Chicago); our team collaborates with, and contributes to, the FLASH project. We discuss the resources required for the whole project, the I/O management, the performance and the scalability of the code on IBM/Sp4 at CINECA. Finally, we present a selection of results. © 2005 IEEE.
A Shoreline model for breaking waves
2011
In order to simulate the wave motion and, in turn, the flow, within the nearshore region, in the last decades the derivation and the application of depth-integrated type of models have been widely investigated and developed. However, in such models, the problems of facing wave breaking and the moving shoreline are not trivial and therefore several approaches have been proposed. About wave breaking, approaches both based on the adoption of an artificial eddy viscosity Zelt (1991) and on the concept of roller Veeramony (2000), Karambas (2003), Musumeci (2005) have been implemented. As regards the shoreline boundary condition, a couple of numerical techniques have been mainly adopted, namely t…
Field run-up measurements: Calibration of a physically based lagrangian shoreline model
2012
In the present contribution a measurement technique based on video imaging has been selected for the assessment of the maximum run-up. Such measurements have been used for the calibration of a numerical model and of an empirical formulation. The on-site run-up measurements have been carried out at “Lido Signorino” beach, near Marsala, Italy. The positions of the swash have been localized on a transect, normal to the shore, constituted by stakes placed at 0.5 m intervals each other. The video camera was placed orthogonally to the line of the stakes. For the numerical simulations a 1DH Boussinesq-type of model for breaking waves has been applied which takes into account the wave run-up by a L…
