BACKGROUND AND AIMS It is well known that a large portosystemic shunt develops during portal hypertension. In this study, we studied the long-term effects of a large splenorenal shunt (SRS) on liver function and survival. METHODS The subjects were divided into three groups: an SRS (-) group consisting of cirrhotic patients without SRS; an SRS (+) group(More)
Cortical and spinal root (C(8)-T(1)) magnetic stimulation evoked single motor unit potentials in the abductor pollicis brevis and abductor digiti minimi muscles in a patient with chronic motor neuron disease. This patient was unique in that there were few surviving motoneurons in these muscles making it possible to record single motor units. Central motor(More)
The effects of nighttime nap and age on sleep patterns of shift workers were examined for two groups of young and older guards working a 24-h shift with a nighttime nap of approximately 3.2 h. For both groups, day sleep was reduced by approximately 4.1 h, mainly affecting stage 2 sleep, slow wave sleep (SWS), and REM sleep. The totals of the different sleep(More)
Isolated gastric varices (IGV) have a lower risk of bleeding than esophageal varices, however IGV bleeding is associated with a higher mortality than bleeding of esophageal varices. In recent years, two widely used treatments for IGV have been balloon-occluded retrograde transvenous obliteration (B-RTO) and endoscopic injection sclerotherapy (EIS) using(More)
Intractable severe pulmonary edema during Orthotopic Liver Transplant (OLT) can be a fatal perioperative complication. We sought to characterize the incidence, timing, and related risk factors of severe pulmonary edema during OLT. We performed a retrospective observational survey of OLT cases performed between 2007 and 2011 at Miami Transplant Institute. Of(More)
BACKGROUND/AIMS Esophageal varices are often seen in cirrhotic patients. Because endoscopic therapy for esophageal varices forces such patients to go on an extended fast until the endoscopic therapy occurs, physical and psychological stresses are induced. The aims of this study were to investigate the effects of a nutritional supplement before endoscopic(More)
