STRUCTURAL ANALYSIS OF A POSTERIOR STABILITY TOTAL KNEE JOINT REPLACEMENT

2011

Aim of this work is to compare two different total knee prostheses that differ in the shape of the Polyethylene (PE) insert, trying to optimize the shape of the best one, in order to reduce the stress peaks. The study procedure has been divided into the following steps. First step has been the three-dimensional shape acquisition of the two prostheses by means of a COMET5 3D scanner. The morphology of two prototypes of the prostheses has been acquired by elaborating multiple Moirè fringe pattern projected on their surfaces. Second step consisted of the manipulation of these data in a CAD module, that is the interpolation of raw data into parametric surfaces, reducing singularities due to the…

Study of a constrained finite element elbow prosthesis: the influence of the implant placement

2023

Abstract Background The functional results of total elbow arthroplasty (TEA) are controversial and the medium- to long-term revision rates are relatively high. The aim of the present study was to analyze the stresses of TEA in its classic configuration, identify the areas of greatest stress in the prosthesis–bone–cement interface, and evaluate the most wearing working conditions. Materials and methods By means of a reverse engineering process and using a 3D laser scanner, CAD (computer-aided drafting) models of a constrained elbow prosthesis were acquired. These CAD models were developed and their elastic properties, resistance, and stresses were studied through finite element analysis (fin…

Evaluation of diagnostic criteria for analgesic nephropathy in patients with end-stage renal failure: results of the ANNE study

1995

It was found that in Belgium, renal imaging techniques, demonstrating a decreased renal mass of both kidneys combined with either bumpy contours or papillary calcifications, were the only methods to reliably diagnose analgesic nephropathy (AN) in patients with end-stage renal failure. However, these criteria were selected in an area with a high prevalence of this disease (15.6% of the dialysis population at December 1990). To evaluate the criteria selected to diagnose AN in populations with lower or unknown prevalences of AN, the Analgesic Nephropathy Network of Europe (ANNE) was formed, consisting of 23 dialysis units from 14 European countries and Brazil. During 1991-1992, 598 new patient…

Fabry nephropathy: 5 years of enzyme replacement therapy-a short review.

2007

Fabry disease is an X-linked lysosomal storage disease, resulting from a deficiency of the enzyme α-galactosidase A and subsequent cellular storage of the enzyme substrate globotriaosylceramide (Gb3) [1]. Estimates of the incidence of Fabry disease vary markedly, from 1:<5000 male births in a newborn screening study in Italy [2] to 1:117 000 male births in Australia [3] and 1:833 000 male births in northern Portugal [4]. In general, hemizygous males are more severely affected than heterozygous females. In males, life expectancy is reduced by an average of 20 years [5] and in females by 15 years [6]. Although males tend to suffer symptoms earlier than females, both boys and girls can be affe…

Irritative and sensory disturbances in oral implantology. Literature review.

2010

The aim of this study was to review irritative and sensory disturbances following placement of dental implants. A literature search was made of PubMed for articles published between 2000 and 2010. Studies that reported sensory disturbances directly caused by the placement of dental implants were included. Sensory deficits or trigeminal neuropathy are caused by damage to the third branch of the trigeminal nerve du-ring surgery. This manifests in the immediate postoperative period as a sensory deficit not usually associated with pain and generally transient. The literature reviewed reported irritative and sensory disturbances caused during surgery, after surgery, and as a result of complicati…

What employability for higher education students?

2020

International audience; The Bologna process has contributed to redefining the concept of employability in higher education policies. In parallel, the professionalisation movement of French higher education has become more pronounced, notably through the development of work placements within the university curricula. In this article, we propose to re-examine the definition of employability of the ‘dominant’ discourse which is strongly centred on a competency-based approach and individualisation. We highlight the importance of having a broader definition of employability by integrating subjective dimension of employability and students' representations of the world of work. Based on an origin…

Brand placement en videojuegos con y sin realidad virtual: eficacia en el consumidor adolescente

2019

El veloz desarrollo de la tecnología ha propiciado cambios en la forma EN QUE SE comunican no solo los individuos, sino también las empresas. Un claro ejemplo es la publicidad, que ha tenido que acudir a estrategias menos tradicionales. Es el caso del brand placement (BPL), una estrategia publicitaria poco convencional que consiste en emplazar marcas de manera integrada y poco intrusiva en contextos no propios de la publicidad. Aunque se originó en el cine, actualmente su uso se ha extendido a otros medios, como los videojuegos, donde la presencia de marcas es cada vez más notoria. Se trata de un sector en auge a nivel mundial, europeo y español, y una novedosa forma de entretenimiento, lo …
