BACKGROUND The proportionally higher incidence of intracranial atherosclerosis among Asian and black patients and a greater proclivity for intracranial artery stenosis in the Hispanic population merit drawing attention to a Latin American experience with intracranial arterial stenting. METHODS This is a retrospective analysis of an observational study of(More)
The case of a 66-year-old woman with several episodes of hemorrhage by esophageal varices and ascites due to portal hypertension is presented. Despite 4 sessions of endoscopic sclerotherapy bleeding recurred. A transjugular intrahepatic portosystemic shunt was performed. In the 10 months following the intervention, there was no further hemorrhage, the(More)
Patients with multiple myeloma (MM) and severe renal impairment (SRI) have shorter survival than MM patients without renal failure. Although lenalidomide is a highly active drug, this immunomodulatory agent is frequently neglected in this context due to its predominant renal clearance and, consequently, an increased risk of toxicity. This risk might be(More)
The Level 1 Processing of SMOS transforms the data acquired by MIRAS (Microwave Imaging Radiometer with Aperture Synthesis) into geolocated TOA Brightness Temperatures, providing observation angles and additional parameters for the Level 2 Processor. Prior to SMOS launch in November 2009 the Level 1 Prototype Processor (L1PP) lead the way for specifying(More)
The aim of this study was to compare the accuracy of computed tomography (CT) and single photon emission computerized tomography (SPECT) in the diagnosis of dementia. Fifty-two patients with clinical diagnosis of dementia and 11 controls were studied. The scans were interpreted by one experienced neuroradiologist and one nuclear radiologist, both blinded to(More)
An optical simulator of the human eye and its application to laser dazzle events are presented. The simulator combines optical design software (ZEMAX) with a scientific programming language (MATLAB) and allows the user to implement and analyze a dazzle scenario using practical, real-world parameters. Contrary to conventional analytical glare analysis, this(More)
True posterior communicating artery aneurysms are extremely rare with incidence ranges from 0.1% to 2.8% of all aneurysms. Cerebral aneurysm formation has been reported as a complication of artery occlusion by flow alteration. We present a 69 years old male patient presenting with subarachnoid hemorrhage with diagnosis of true right posterior communicating(More)
