To do this, we created an original database of 590 international treaties that Chile subscribed in the period, and analyzed it using quantitative techniques. The paper argues, first, that the participation of IGs in the matter is rather low, and that the participation pattern is highly unbalanced. Second, our preference attainment analysis underlies that the agreement between the preferences of business IGs and the content of treaties is no greater than that of other type of IGs.

Lamentablemente suelen presentar disfunción principalmente por estenosis, lo que conlleva a indicar su reemplazo con el consiguiente aumento de la morbimortalidad de repetidas cirugías. La angioplastia con stent del homoinjerto aparece entonces como una opción terapéutica para prolongar su vida útil y posponer la cirugía. Se presenta el caso de una mujer de 21 años que requirió múltiples intervenciones para la corrección de una atresia pulmonar con comunicación interventricular.

We present a framework to manage multimodal interfaces and applications in a reusable and extensible manner. We achieve this by focusing the architecture both on devices ’ Capabilities and users ’ Intentions. One particular domain we want to approach is collaborative environments where several modalities and applications make it necessary to provide for an extensible system combining diverse components across heterogeneous platforms on-the-fly.We demonstrate how to connect different applications and users around an immersive environment (tiled display wall), including different non-conventional input modalities and applications.

The human body is presented as a rich repository of meaningful relations which are always available to interact with. Preliminary studies were carried and validate mnemonical body shortcuts as a new mobile interaction mechanism.

Depending on the presence of hemodynamic compromise, coronary fistulas may be treated with a conservative approach, with surgery or, recently, with transcatheter closure. We present a case report of a patient with a large coronary-cameral fistula treated with percutaneous embolization with Amplatzer vascular plug. No complications developed during the procedure and follow-up.

Therefore, endovascular treatment either by chemical embolization or exclusion of defect with devices has emerged as an alternative treatment. However, there are risks such as occlusion of visceral vessels near the neck of the defect, embolization material or aortic rupture. Therefore, the choice of material and method of approach should be planned carefully in each case. We report a patient who ten years after abdominal wound firearm was diagnosed with AAP 17 x 13 cm, with short neck originated close to the ostium of the celiac trunk at an acute angle with the aortic axis. We perform the exclusion of the defect with a device designed for closing atrial septal defect from the left brachial access due to the angulation of the neck defect. There were no complications. ...

The ductus arteriosus had several different morphologic forms, and there was one postsurgical recanalization of the ductus arteriosus. The median minimum ductal diameter was 1.8 mm and the median maximum aortic ampulla diameter was 6.5 mm. The occlusion rate immediately after intervention was 53.5%, which increased to 95.2% by 12 months and to 100% by 18 months. The median follow-up time was 20.5 months. The Nit-Occlud device provided an effective and safe means of patent ductus arteriosus closure, irrespective of ductus morphology.

Subsequently, when this is no longer considered necessary and closure is indicated, the method of choice is percutaneous embolization using various coils or other devices. We report on a series of patients in whom this type of shunt was closed successfully via an arterial approach using a new device: the Amplatzer Vascular Plug. In addition to employing a controlled-release system, this type of plug has the advantage that it can be implanted using low-profile catheters. The patients were 1, 4, and 23-years-old, respectively, and no complications were reported. The fluoroscopy time was 10, 11, and 9 minutes, respectively, and patients were followed up for 42 months.

Patients aged 9 and 11 years, with SaO2 of 88 and 96%, respectively. One of them coursing with headaches and functional class II. Both patients with total cavopulmonary anastomosis and fenestrated extracardiac conduit and permeable pulmonary artery (pulsatile Fontan). An Amplatzer duct-occluder device was implanted in the pulmonary artery entering from the femoral vein. Follow-up by means of clinical examination, imaging, and catetherization was pursued. Case 1, patency fenestration, Qp/Qs: 0.7/1. Case 2, closed fenestration, Qp/Qs; 1.3/1. We obtained immediate occlusion with 6/4 and 8/6 devices, respectively; pressure recordings revealed modification of the arterial morphology to biphasic; pulmonary pressure dropped 2 mm Hg in the first patient, without alteration in the second case; no changes in SaO2 were registered. Time of fluoroscopy was 57 and 45 minutes, respe...

Desde octubre de 1992 hasta agosto de 2008, fueron referidos a nuestro servicio 23 pacientes con conducto arterioso persistente aislado; edad, 16-75 años (mediana, 25,5); peso, 52-80 kg (mediana, 57); diámetro pulmonar, 1,8-5,8 mm (media, 3,5); presión media en la arteria pulmonar, 9-72 mmHg (media, 15). Las tasas de oclusión fueron del 85,7% con los dispositivos Rashkind-PDA y del 100% con Amplatzer Duct-Occluder y Nit-Occlud coil. Tiempo medio de internación y seguimiento: 24 h y 2 años respectivamente. La única complicación inmediata fue un hematoma inguinal; no hubo complicaciones alejadas. En adultos, el cierre del conducto arterioso con diferentes dispositivos, especialmente los de última generación, resultó seguro y eficaz, independientemente de su morfología y estado histológico.

Los conductos tuvieron una variada morfología, e incluían una recanalización posquirúrgica. Las medias del diámetro ductal mínimo y el extremo aórtico fueron de 1,8 y 6,5 mm, respectivamente.
