Pylephlebitis is a condition with significant morbidity and mortality. We review herein 100 relevant case reports published since 1971. Eighty-one patients were reported with acute pylephlebitis, while the remaining patients had chronic pylephlebitis. The most common predisposing infections leading to pylephlebitis were diverticulitis and appendicitis.(More)
Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome and can vary from benign steatosis to end-stage liver disease. The pathogenesis of non-alcoholic steatohepatitis (NASH) is currently thought to involve a multiple-hit process with the first hit being the accumulation of liver fat which is followed by the(More)
Cytotoxin-associated gene A (CagA) diversity with regard to EPIYA-A, -B, -C, or -D phosphorylation motifs may play an important role in Helicobacter pylori pathogenesis, and therefore determination of these motifs in H. pylori clinical isolates can become a useful prognostic tool. We propose a strategy for the accurate determination of CagA EPIYA motifs in(More)
OBJECTIVES Tumor infiltrating lymphocytes (TILs) and T regulatory cells (Tregs) have been associated with prognosis in ovarian cancer, but their prognostic significance in ascites has not been studied. We performed a prospective study of T lymphocytes isolated from ascites from patients with ovarian carcinoma and we compared them with the respective(More)
BACKGROUND AND AIMS In chronic hepatitis C and non-alcoholic fatty liver disease, apoptotic caspases are activated in liver, and serum caspase activity has been suggested as a sensitive marker of early liver injury. An investigation was carried out into whether the serum levels of caspase-generated fragments of cytokeratin-18 (CK-18) are associated with the(More)
BACKGROUND Jejunogastric intussusception (JGI) is a rare but potentially very serious complication of gastrectomy or gastrojejunostomy. To avoid mortality early diagnosis and prompt surgical intervention is mandatory. CASE PRESENTATION A young man presented with epigastric pain and bilous vomiting followed by hematemesis,10 years after vagotomy and(More)
Leptin and adiponectin, the main metabolic products of adipose tissue, have been implicated in a wide spectrum of human diseases. Given the frequent presence of hepatic steatosis in several chronic liver diseases, there is currently increasing interest in the role of these adipokines in the development of hepatic steatosis and also in necroinflammation and(More)
BACKGROUND Adverse drug reactions (ADRs) are a significant cause of morbidity and mortality. METHODS A prospective study was conducted over a 6-month period. All patients consecutively admitted were enrolled in the study. Analysis included: (1) an evaluation of the frequency of ADR-related hospital admissions and their causality, severity, and(More)
BACKGROUND & AIMS The aim was to systematically review the interactions between Helicobacter pylori (HP) infection and NSAID use on the risk of uncomplicated or bleeding peptic ulcer. METHODS All relevant full articles published in MEDLINE from January 1989-June 2004 were included. Sensitivity analyses for type of controls or use of aspirin or non-aspirin(More)
Currently available options for the treatment of chronic hepatitis B virus (HBV) infection include standard and pegylated interferon alfa and four oral antiviral agents (lamivudine, adefovir, entecavir, and telbivudine). These treatment strategies are either therapies of finite duration that aim to achieve sustained off-therapy responses, or long-term(More)
