Method for 3D fibre reconstruction on a microrobotic platform
2015
Automated handling of a natural fibrous object requires a method for acquiring the three-dimensional geometry of the object, because its dimensions cannot be known beforehand. This paper presents a method for calculating the three-dimensional reconstruction of a paper fibre on a microrobotic platform that contains two microscope cameras. The method is based on detecting curvature changes in the fibre centreline, and using them as the corresponding points between the different views of the images. We test the developed method with four fibre samples and compare the results with the references measured with an X-ray microtomography device. We rotate the samples through 16 different orientatio…
Automated Dental Identification with Lowest Cost Path-Based Teeth and Jaw Separation
2016
Abstract Teeth are some of the most resilient tissues of the human body. Because of their placement, teeth often yield intact indicators even when other metrics, such as finger prints and DNA, are missing. Forensics on dental identification is now mostly manual work which is time and resource intensive. Systems for automated human identification from dental X-ray images have the potential to greatly reduce the necessary efforts spent on dental identification, but it requires a system with high stability and accuracy so that the results can be trusted. This paper proposes a new system for automated dental X-ray identification. The scheme extracts tooth and dental work contours from the X-ray…
Quistes de uraco en adultos. Presentación de 3 casos y revisión de la literatura
2022
Resumen El uraco es un grueso cordon fibroso que aparece a partir del quinto mes de gestacion como consecuencia de la obliteracion de la alantoides. Los quistes de origen uracal se producen como consecuencia de un defecto en la obliteracion de dicho conducto, anomalia que se detecta principalmente en ninos y raramente en adultos. Presentamos 3 casos de quistes uracales en adultos, uno de ellos detectado durante el estudio de dolor abdominal y los otros 2 hallados de forma incidental durante el estudio de otras patologias. En ningun caso se sospecho clinicamente la posibilidad de quistes uracales. Histologicamente, estas lesiones se encuentran revestidas por epitelio de tipo urotelial con ex…
El documento de voluntades anticipadas. Comparativa de la legislación actual en el marco de la Unión Europea
2021
Resumen La Ley 41/2002, de 14 de noviembre, basica reguladora de la autonomia del paciente da valor legal vinculante a las voluntades anticipadas (VA) en Espana. Sin embargo, la situacion en cada pais de la Union Europea es distinta y desconocida para la mayoria del personal sanitario. Para conocer esas diferencias, se realizo una recogida y estudio de las distintas legislaciones en materia de derechos del paciente, y se establecio una comparativa actualizada de las caracteristicas que cada pais otorga a las VA. De los 28 paises de la Union Europea, 15 han desarrollado legislacion especifica en materia de VA, y le otorgan caracter vinculante el 86% si se utiliza la formulacion escrita. Siet…
CO-74: Altérations majeures du sphingophospholipidome des lipoprotéines de haute densité (HDL) de patients avec syndrome métabolique et glycémie norm…
2016
Rationnel Les phospholipides et sphingolipides jouent un role primordial dans la fonctionnalite et le role anti-atherogene des HDL. Ces proprietes sont alterees chez les patients porteurs d'un syndrome metabolique avant meme l'apparition d'une hyperglycemie. Nous avons donc recherche si les HDL de ces patients presentaient des anomalies de leur sphingophospholipidome. Patients et Methodes Par chromatographie liquide couplee a la spectrometrie de masse en tandem, nous avons quantifie 80 especes moleculaires des principales classes de phospholipides et sphingolipides des HDL2 et HDL3, chez 26 patients avec un syndrome metabolique et une glycemie a jeun nor-male (14 hommes, 12 femmes, âge moye…
Étude de prévalence de l’endométriose à la Réunion et en métropole à partir du PMSI
2015
Introduction Objectif principal : determiner la prevalence des hospitalisations pour endometriose a la Reunion et en metropole. Objectif secondaire : apprecier l’evolution des soins chirurgicaux pour cette pathologie dans l’ile comparee a la metropole. L’endometriose est une maladie de la femme reglee. Les principaux modes de decouverte sont la douleur et l’infertilite. Le diagnostic de certitude repose sur la cœlioscopie et donc sur une hospitalisation. Methodes Du 1/01/2008 au 31/12/2012, a partir du PMSI national, nous avons releve les codes de diagnostic principal concernant l’endometriose (N800 a N809). Dans cette population, nous avons consulte les actes realises et ceux qui concernai…
Incidence de l’endophtalmie aiguë postopératoire après chirurgie de la cataracte par phacoémulsification et injection intracamérulaire d’antibiotique…
2016
National audience; Introduction La chirurgie de la cataracte est l’intervention la plus fréquente dans le monde. Parmi ses complications, l’endophtalmie aiguë postopératoire (EAPO) est une infection intraoculaire sévère, qui peut conduire à la cécité. Les objectifs étaient de déterminer l’incidence de l’EAPO après chirurgie de la cataracte par phacoémulsification en France de 2005 à 2014 et d’analyser l’association entre injection intracamérulaire d’antibiotique (IICA) et EAPO. Méthodes Tous les patients hospitalisés pour une chirurgie de la cataracte en France entre le 1er janvier 2005 et le 31 décembre 2014 ont été identifiés dans le programme de médicalisation des systèmes d’information …
Effect of different solutions in reversing the damage caused by radiotherapy in dentin structure
2020
Background Previous studies have shown that radiotherapy of the head and neck region can cause direct changes in dental structure. This study evaluated the effect of different solutions on the dentin chemical composition and collagen structure of irradiated dentin. Material and Methods Sixty maxillary canines were distributed in 2 groups (n=30): non-irradiated and irradiated (radiotherapy: X-rays of 6 MV in 30 cycles of 2 Gy to 60 Gy). The teeth were sectioned, sanded, and polished to obtain 3x3x2 mm fragments, which were redistributed in 3 subgroups (n=10) according to the treatment employed: chlorhexidine 2% (CL), chitosan 0.2% (QT), and 0.5 M carbodiimide (EDC). The samples were analyzed…
The montrachet study
2016
National audience; Summary The Montrachet Study (Maculopathy Optic Nerve nuTRition neurovAsCular and HEarT diseases) is a population‐based derived from the 3C Study performed in Dijon. In 2009–2011, 1153 participants from the 3 Cities Study, aged 75 years or more, had an initial eye examination. Apart from the old age of this population, the main interest is that information on cardiovascular and neurologic diseases and a large comprehensive database (blood samples, genetic testing, cognitive tests, MRI) were available. Our first results showed us that despite the high prevalence of self‐reported eye diseases in this elderly population, visual impairment was low and increased with age. Thes…
10-Year Journey Through Brain Gliomas: Case Report
2020
Abstract We present the case of a 28-year-old doctor who was diagnosed in 2009 with grade II oligodendroglioma. In the next 10 years he underwent 4 surgeries, passing in turn through 3 different types of cerebral gliomas: grade II oligodendroglioma, grade III oligoastrocytoma and IDH Wild-Type glioblastoma. In the spirit of the surgical resection limited by the preservation of the function, he was able to practice his medical profession until the last months of his life. Life expectancy at the time of diagnosis complied with all the statistical data. Although the etiology, pathophysiology and treatment of cerebral gliomas is still full of unknowns, knowing our limits we can provide a good q…
