OBJECTIVES Nonalcoholic steatohepatitis (NASH) associated with obesity and type 2 diabetes mellitus (DM) is postulated to be the cause of most cases of cryptogenic cirrhosis (CC). While ethnic differences in the prevalence of obesity and DM in the United States are well documented, there is little information regarding prevalence of CC or NASH among(More)
OBJECTIVE The aim of this study was to analyze the clinical presentation and outcomes of significant pulmonary toxicity associated with interferon and ribavirin. METHODS We conducted a retrospective review of patients enrolled in four clinical trials at three sites, two academic medical centers and one community practice, and reviewed the literature. (More)
The Model for End-Stage Liver Disease (MELD) has been proposed as a replacement for the Child-Turcotte-Pugh (CTP) classification to stratify patients for prioritization for orthotopic liver transplantation (OLT). Improved classification of patients with decompensated cirrhosis might allow timely OLT before the development of life-threatening complications,(More)
BACKGROUND Depth of invasion beyond the muscularis propria (MP) by T3 rectal cancer can vary. The purpose of the present paper was to determine if depth of invasion beyond MP, as assessed by preoperative endoscopic ultrasound (EUS), can predict tumor recurrence in patients with T3 rectal tumors. METHODS Patients with T3NxM0 rectal cancer, as determined by(More)
Hyperhomocysteinaemia, a risk factor for recurrent pregnancy loss, is related either to a hereditary defect within the methionine-homocysteine pathway or it might be acquired as a result of deficiencies of vitamin B(12) and folate (B(9)). Because hyperhomocysteinaemia seems to be determined by both genetic and environmental factors, the current study was(More)
BACKGROUND Conventional interferon monotherapy fails to achieve virological clearance in most hepatitis C-infected patients. The use of high-dose induction regimens may improve the initial clearance of virus, while the addition of ribavirin appears to improve the rates of sustained response once clearance is achieved. AIM To compare the efficacy and(More)
Pentoxifylline (PF) is used to enhance motility of spermatozoa from infertile human subjects. We have previously shown that 0.45 mM PF improved capacitation of spermatozoa and fertilization of oocytes in vitro in hamsters. The present study was carried out to assess PF-induced changes in motility kinematics of hamster spermatozoa by a computer-aided sperm(More)
Nonalcoholic steatohepatitis (NASH) is a liver disease that, until recently, has been underrecognized as a common cause of elevated liver enzymes. This distinct clinical entity is characterized by liver biopsy findings similar to those seen in alcoholic hepatitis but in the absence of alcohol consumption sufficient to cause such changes. Patients with NASH(More)
BACKGROUND AND AIM Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the most accurate imaging modality for locoregional staging of esophageal cancer. It remains unclear whether this technology impacts on the outcome of patients with this malignancy. The aim of the present study was to assess the impact of EUS FNA by comparing the clinical(More)
Selenium is an essential trace mineral required for normal human health and reproduction. In recent years selenium deficiency in humans has been implicated as a risk factor for recurrent pregnancy loss. So far the selenium status in recurrent pregnancy loss (RPL) has been evaluated only in plasma and serum samples showing discrepancies of selenium(More)
