Color Doppler sonography in the study of chronic ischemic nephropathy  

British Library Electronic Table of Contents (United Kingdom)

SommarioNei Paesi occidentali il rischio di malattie cardiovascolari e notevolmente aumentato negli ultimi decenni. Di pari passo, il miglioramento prognostico delle malattie cardiovascolari, l'invecchiamento e l'aumento della vita media della popolazione generale stanno rivelando un crescente numero di casi di malattia renale cronica d'origine vascolare. E del tutto plausibile pensare che nei prossimi anni il numero di pazienti anziani con malattia vascolare aterosclerotica, che sara inserito nei programmi di dialisi cronica, aumentera rapidamente. Questo fara lievitare in modo drammatico i costi sociali ed economici della dialisi configurando una vera emergenza clinica. In questo scenario epidemiologico, la diagnosi precoce della malattia ischemica cronica del rene e la definizione di nu...

Decision making information systems and data base management; Applicazioni dei sistemi di supporto alle decisioni manageriali in un ente fortemente decentrato. Sviluppo di un prototipo per la valutazione di nuovi progetti  

Energy Technology Data Exchange (ETDEWEB)

In these years Information Technology has been used in activities that require an intelligent intervention. In this context take placing Decision Support Systems, since they use Information Technology to support users in decision processes, that is problems of logical level greater then problems normally treated by traditional information systems. The purpose of this work is to describe Decision Support Systems specifying what they are, their functionally and structure, identifying, furthermore, user types referred to and interaction modality between them; and to present a prototype of these systems. From a preliminary analyses phase of ENEA being and its Information Systems to understand which topics can be supported by systems of this type, it deals with one of these topics: weighing of new project, finding parameters, or key quantity, that affect and determine decisions. It describes, then, models, conceived form parameters, that permit to the user, through a simple representation ...

CT assessment of thoracic gunshot wounds. Our personal experience; Ruolo della Tomografia Computerizzata nelle lesioni da arma da fuoco del torace. Esperienza personale  

Energy Technology Data Exchange (ETDEWEB)

CT is a valuable tool in assessing thoracic gunshot wounds. CT is also the method of choice in emergency, because it permits rapid depiction of bullet damage to the chest and to other body districts. This in turn permits correct assessment of the main thoracic injuries, plus adequate and prompt planning of surgical treatment or support intensive care. It is reported on the role of CT in diagnosing the complex pleuropulmonary, cardiovascular and thoracic wall injuries caused by gunshot wounds, with their specific and acute signs which differ greatly fro those of other types of chest trauma. In the last 4 years, it was observed an amount of 76 cases of gunshot injury, twenty-six of them involved the chest. The patients, 25 men and 1 woman (mean age: 32 years, range: 17-48), were all submitted to emergency CT with iv contrast agent injection and the CT-angiography technique. The reanimator was always presented to monitor the patients' vital functions and shock state. CT of the ...

CT assessment of blunt diaphragmatic injuries. A retrospective study on 35 cases; Sensibilita' diagnostica della Tomografia Computerizzata nei traumi chiusi del diaframma. Studio retrospettivo di 35 casi consecutivi  

Energy Technology Data Exchange (ETDEWEB)

Purpose of this work is to evaluate the effectiveness and role of CT in blunt diaphragmatic injuries by reviewing our 8-year experience. It is reviewed the preoperative CT findings of 35 patients with surgically confirmed diaphragmatic rupture. Surgical repair was performed in the acute setting (within 12 hours of trauma) in 22 cases, and late (8 months-5 years) in 13 cases. Twenty-eight patients (80%) were examined with conventional CT and 7 (20%) with Helical CT. Of the 13 patients examined long after trauma, the left hemi diaphragm was ruptured in 12 cases (with visceral herniation in 4), and the right hemi diaphragm in 1, with no herniation. The diaphragmatic rent was found in the dome (15 cases, 43%), muscolotendinous junction (11 cases, 31%), muscular portion (8 cases, 23%), and at the muscular attachments on the ribs (1 case, 3%). As for the site of diaphragmatic injury, CT never depicted the diaphragmatic rent in the dome and at the muscolotendinous junction (74%), not even ...

Liver trauma from penetrating injuries. Miscellanea, personal series, clinical and CT findings; Traumi epatici da lesioni penetranti. Miscellanea, casistica personale, aspetti clinici e con Tomografia Computerizzata  

Energy Technology Data Exchange (ETDEWEB)

Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. In this report are examined the clinical and radiological findings of personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. It will also tried to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years it was retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different cases. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the ...

CT in the study of thoracic-pulmonary complications after liver transplantation; La Tomografia Computerizzata nello studio delle complicanze toraco-polmonari dopo trapianto del fegato  

Energy Technology Data Exchange (ETDEWEB)

In this article is reviewed the role of Computed Tomography (CT) in thoracic complications following ortho topic liver transplantation (OLT). In a post-OLT population of 567 patients transplanted in the Italian institutions, 100 patients (17.6%) were examined with chest CT. It was reviewed data relative to the total number of examinations, clinical and/or radiographic indications, the CT technique-i.e., conventional (with (out) intravenous, i.v., contrast material) or high-resolution (HRCT). It also reviewed the radiologic patterns and their correlation with the other clinical, bronchoscopic and/or laboratory results. Of 152 chest CT examinations, 45 (29.6%) were performed because of clinical indications, 31 (20.4%) because of a radiographic abnormality, 64 (42.1%) because of clinical and radiographic abnormality, 64 (42.1%) because of clinical and radiographic indications, while in 12 cases (7.9%) the reasons were unknown; 133/152 (87.5%) examinations had been performed with ...
