Cirugia de la enfermedad por reflujo gastroesofagico: Estudio comparativo entre los abordajes laparoscopico y abierto.
2001
I. INTRODUCCIÓNLa prevalencia en la población general es del 0,36%, representando la segunda enfermedad digestiva, detrás de la úlcera duodenal, que con más frecuencia es motivo de consulta médica. Desde el punto de vista fisiopatológico la ERGE resulta del tránsito mantenido del jugo gástrico, ya sea ácido y/o duodenal o yeyunal, en sentido retrógrado hacia el esófago, en ausencia de vómito o eructo. En la actualidad las exploraciones complementarias permiten el diagnóstico fidedigno de la enfermedad por reflujo gastroesofágico. La efectividad del tratamiento médico junto con la aparición del abordaje laparoscópico, serán causa de controversia al valorarse las indicaciones de la cirugía. N…
Accidentabilidad laboral: Accidentes oculares.
2005
INTRODUCCIONEl número de accidentes de trabajo es elevado. España tiene el índice más alto de accidentes no mortales de toda la Unión Europea y el tercero en los accidentes mortales.Su coste económico oscila sobre los 1200 millones de euros al año. En Estados Unidos, España, Suiza, Latinoamérica y el Caribe representa el 2-4% del PIB.Los accidentes oculares constituyen el 10% de todos los accidentes del cuerpo, y suelen ser leves.MATERIAL Y METODOHemos estudiado los accidentes de trabajo con baja ocurridos a los trabajadores que tienen cubierta dicha contingencia.Los documentos fueron el parte de accidente de trabajo con baja y la relación de altas o fallecimientos.En el estudio de los cost…
INFLUENCE OF ISLET TRANSPORTATION ON PANCREATIC ISLET ALLOTRANSPLANTATION IN TYPE 1 DIABETIC PATIENTS WITHIN THE SWISS-FRENCH GRAGIL NETWORK
2004
The influence of islet transportation on pancreatic islet allotransplantation in type 1 diabetic patients was evaluated within the GRAGIL network.From December 2001 to April 2003, 16 human pancreatic islet transplants were performed in 9 type 1 diabetic patients with an established kidney graft (functioning for at least 6 months) in four centers of the GRAGIL network. Islet isolation was performed in a core laboratory in Geneva, and the islet preparations were shipped by ambulance to each center for transplantation. One month after transplantation, the efficiency of the graft was assessed according to islet transportation time (ITT): ITT less than 2 hours (group 1, n=5), and ITT greater tha…
Restauración de la acomodación tras la cirugía de cataratas: lentes intraoculares acomodativas.
2008
INTRODUCCIÓN: Uno de los retos de la cirugía de catarata moderna es restaurar laacomodación. Debido al diseño de las lentes intraoculares (LIOs), estas no varía sumorfología en respuesta a la contracción del músculo ciliar durante el esfuerzoacomodativo. Las LIOs acomodativas son una alternativa propuesta en la restauraciónde la acomodación. Van a transformar la fuerza de contracción del músculo ciliar en unmovimiento anterior de la óptica a lo largo del eje visual que se traduce en un cambio enel poder refractivo del ojo.OBJETIVO: El objetivo del estudio es evaluar la seguridad y eficacia de la LIOacomodativa de Acuity, en pacientes pseudofáquicos después de una intervención decataratas.MA…
Thinking about movement hurts: The effect of motor imagery on pain and swelling in people with chronic arm pain
2008
Objective: Chronic painful disease is associated with pain on movement, which is presumed to be caused by noxious stimulation. We investigated whether motor imagery, in the absence of movement, increases symptoms in patients with chronic arm pain. Methods: Thirty‐seven subjects performed a motor imagery task. Pain and swelling were measured before, after, and 60 minutes after the task. Electromyography findings verified no muscle activity. Patients with complex regional pain syndrome (CRPS) were compared with those with non‐CRPS pain. Secondary variables from clinical, psychophysical, and cognitive domains were related to change in symptoms using linear regression. Results: Motor imagery in…
Withholding or withdrawing of life-sustaining therapy in older adults (≥ 80 years) admitted to the intensive care unit
2018
PURPOSE: To document and analyse the decision to withhold or withdraw life-sustaining treatment (LST) in a population of very old patients admitted to the ICU. METHODS: This prospective study included intensive care patients aged ≥ 80 years in 309 ICUs from 21 European countries with 30-day mortality follow-up. RESULTS: LST limitation was identified in 1356/5021 (27.2%) of patients: 15% had a withholding decision and 12.2% a withdrawal decision (including those with a previous withholding decision). Patients with LST limitation were older, more frail, more severely ill and less frequently electively admitted. Patients with withdrawal of LST were more frequently male and had a longer ICU len…
Discovery of a jet-like structure with overionized plasma in the SNR IC443
2018
IC443 is a supernova remnant located in a quite complex environment since it interacts with nearby clouds. Indications for the presence of overionized plasma have been found though the possible physical causes of overionization are still debated. Moreover, because of its peculiar position and proper motion, it is not clear if the pulsar wind nebula (PWN) within the remnant is the relic of the IC443 progenitor star or just a rambling one seen in projection on the remnant. Here we address the study of IC443 plasma in order to clarify the relationship PWN-remnant, the presence of overionization and the origin of the latter. We analyzed two \emph{XMM-Newton} observations producing background-su…
Mechanical ventilation alters the development of staphylococcus aureus pneumonia in rabbit
2016
Ventilator-associated pneumonia (VAP) is common during mechanical ventilation (MV). Beside obvious deleterious effects on muco-ciliary clearance, MV could adversely shift the host immune response towards a pro-inflammatory pattern through toll-like receptor (TLRs) up-regulation. We tested this hypothesis in a rabbit model of Staphylococcus aureus VAP. Pneumonia was caused by airway challenge with S. aureus, in either spontaneously breathing (SB) or MV rabbits (n = 13 and 17, respectively). Pneumonia assessment regarding pulmonary and systemic bacterial burden, as well as inflammatory response was done 8 and 24 hours after S. aureus challenge. In addition, ex vivo stimulations of whole blood…
Soft tissue integration of different abutment surfaces: An experimental study with histological analysis
2021
OBJECTIVE To evaluate whether abutment surface and surface bio-activation have an effect on soft tissue morphogenesis. MATERIALS AND METHODS 36 patients (36 implants) were included. Abutments were randomly divided into 4 groups (n = 9): Smooth Surface-MAChined (MAC), Ultrathin Threaded Microsurface (UTM), MAC Plasma of Argon activated (Plasma-MAC), and UTM Plasma of Argon activated (Plasma-UTM). After 2 months of healing, soft tissue samples were collected and prepared for histological analysis. The margin of the peri-implant mucosa (PM), the apical extension of the barrier epithelium (aJE), and the apical location of the abutment (AM) were identified. Significances of differences among gro…
