BACKGROUND/AIMS Since few data are available concerning the clinical course of decompensated hepatitis C virus (HCV)-related cirrhosis, the aim of the present study was to define the natural long-term course after the first hepatic decompensation. METHODS Cohort of 200 consecutive patients with HCV-related cirrhosis, and without known hepatocellular(More)
BACKGROUND & AIMS Since the International Ascites Club published the diagnostic criteria of refractory ascites (RA) and hepatorenal syndrome (HRS), there have been few studies assessing the natural history of ascites. The aims of this study were to define the natural history of cirrhotic ascites and to identify prognostic factors for dilutional hyponatremia(More)
BACKGROUND Although chronic alcohol intake and chronic hepatitis C may progress to cirrhosis and hepatocellular carcinoma (HCC), few data are available about survival and probability of developing HCC in decompensated cirrhosis of both aetiologies. METHODS This study identified factors related with probability of developing HCC and survival in a cohort of(More)
The efficacy of transcervical insertions of quinacrine hydrochloride pellets to produce tubal occlusion has been evaluated in a study of 139 women in Santiago, Chile. At one year, the pregnancy rate was 3.1%, an acceptable rate for a nonsurgical method of female sterilization.
To carry out a retrospective analysis of patients with acute dural sinus thrombosis, and the role of cerebral venous congestion in patient management. Twenty-five patients were identified with the clinical and imaging diagnosis of acute dural sinus thrombosis. The imaging diagnosis was by magnetic resonance (MR) and/or computed tomography (CT) venography.(More)
605 women were inserted with plain T-IUDs, 508 patients were inserted with TCu-A devices, and 279 women were inserted with TCu-B devices. In the TCu-A, a 2 cm length of copper wire of .5 mm diameter was wound around the upper aspect of the vertical arm of the T-IUD. In the TCu-B, a 6 cm length of wire of .15 mm diameter was coiled downward over a 1 cm(More)
The safety and efficacy of the repeated transcervical instillation of quinacrine hydrochloride in a suspension of 5 ml of 2% Xylocaine was evaluated in 200 patients. All instillation procedures were performed during the proliferative phase of the menstrual cycle: the second instillation was made in the first menstrual cycle following the initial(More)
BACKGROUND & AIMS Hepatorenal syndrome is a well-characterized type of terminal renal failure that occurs in patients with cirrhosis with ascites. Information about other types of functional renal failure in these patients is scarce. We assessed the incidence and prognosis of different types of functional renal failure in cirrhotic patients with ascites and(More)
Current digital information systems in radiology are insufficient to accommodate the retrieval needs of academicians. Significant efforts are required in retrieving clinical cases for teaching and research. We describe a prototype system that supports intelligent case retrieval based on a combined specification of patient demographics, radiologic findings,(More)
Extensive research has been undertaken to develop a simple method of non-surgical female sterilization. Zipper and associates identified quinacrine hydrochloride as a drug likely to produce tubal occlusion when placed into the uterus. Zipper's early work with a solution of quinacrine led to the development of quinacrine pellets, a delivery system that was(More)
