Objective: This prospective study aimed to determine the prevalence of anti-HDV seropositivity among subjects who had previous hepatitis B virus (HBV) infection.

Methods: Subjects who were admitted to the gastroenterology inpatient clinic of our hospital between August 2016 and July 2017 were screened for previous HBV infection. The subjects who had HBV serology compatible with resolved HBV infection were recruited in the study, and the seroprevalance of anti-HDV was studied.

Data evaluating the presence and characteristics of mesenteric lymph nodes (LNs) in patients with ulcerative colitis (UC) are scarce. The aim of this study is to determine the presence and characteristics of LNs in UC. The LN characteristics in computed tomography (CT), including LN dimension and attenuation, were evaluated retrospectively in 100 patients with UC (61 active and 39 inactive cases).

Background: The aim of the present study was to compare the efficacy, adequacy, side effects, and patient compliance of sodium phosphorus (NaP) and senna solutions when preparing the colon before colonoscopy.

Methods: A total of 137 consecutive patients who were considered for colonoscopy evaluation had randomly received one of two premeditated regimens: 90 mL of oral NaP (NaP group) or 500 mL of 1,000 mg of sennosides A and B calcium +66.6 g of sorbitol (senna group).

Objective: To examine the effectiveness of apparent diffusion coefficient (ADC) values and to compare the reliability of different b-values in detecting and identifying significant liver fibrosis.

Subjects And Methods: There were 44 patients with chronic viral hepatitis (CVH) in the study group and 30 healthy participants in the control group. Diffusion-weighted magnetic resonance imaging (DWI) was performed before the liver biopsy in patients with CVH.

Background: Several noninvasive tests have been developed to determine the degree of hepatic fibrosis in patients with chronic hepatitis C (CHC) without performing liver biopsy.

Aim: This study aimed to determine the performance of the PAPAS (Platelet/Age/Phosphatase/AFP/AST) index in patients with CHC for the prediction of significant fibrosis and cirrhosis and to compare it with other noninvasive tests. To date, no study has evaluated the application of the PAPAS index in CHC-associated liver fibrosis.

Background: Terlipressin is a synthetic vasopressin analogue that is used in the treatment of bleeding esophageal varices and hepatorenal syndrome in patients with cirrhosis. Serious ischemic adverse events, such as skin necrosis involving the extremities, scrotum, trunk, and abdominal skin, are rarely observed. In the literature to date, 20 cases that developed ischemic skin necrosis due to terlipressin usage have been reported.

Aim: To analyze the risk factors of lamivudine treatment failure (LTF) for the long-term use in patients with low viral load (LVL).

Material And Methods: In this multicenter study, 548 antiviral naïve noncirrhotic adult patients with LVL (for HBeAg+ patients HBV DNA <10 9 copies/ml and for HBeAg–patients HBV DNA <10 7 copies/ml) were enrolled. As a control group, 46 lamivudine-initiated patients with high viral load (HVL) were included.

It is estimated that there are over 5,000 species of mushrooms worldwide. Some of them are edible and some are poisonous due to containing significant toxins. In more than 95% of mushroom toxicity cases, poisoning occurs as a result of misidentification of the mushroom by an amateur mushroom hunter.

Aim: We designed this study to investigate the neutrophil lymphocyte ratio as a biomarker in distinguishing colonic polyps which are neoplastic or non-neoplastic.

Materials And Methods: One hundred and twenty-five patients with colonic polyps were enrolled into the study. The following data were obtained from a computerized patient registry database: mean platelet volume (MPV), uric acid (UA), platelet count (PC), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT) and the neutrophil to lymphocyte ratio (NLR).

To assess the role of unfiltered coffee upon carbon tetrachloride (CCl(4)) induced hepatotoxicity in rats. All rats were randomly divided into control group, CCl(4)-treated, unfiltered coffee-treated and CCl(4)/unfiltered coffee-treated. Hepatic damage was induced by repeated intraperitoneal injections of CCl(4) every other day.

Objective: To better identify which clinical, laboratory, radiological and invasive procedures were most useful in diagnosing tuberculous peritonitis and to assess the methods in order to reach the diagnosis in future cases.

Methods: Tuberculous peritonitis cases diagnosed between 2000 and 2006 were reviewed retrospectively. Their clinical presentation, physical examination, laboratory and diagnostic methods were evaluated.

Background And Aim: The aim of the present study was to evaluate the preventive role of genistein, a phytoestrogen with a wide variety of pharmacological effects, in an experimental non-alcoholic steatohepatitis (NASH) model.

Methods: Thirty-six Sprague-Dawley rats were divided into three groups. Group 1 (control) received only a standard rat diet, group 2 (placebo) was given a high fat diet (HFD) plus 0.

Objective: Atherosclerotic cardiovascular diseases caused by traditional and non-traditional risk factors are the most common cause of morbidity and mortality in hemodialysis patients. Recently, much interest has been focused on non-traditional factors, such as oxidative stress, inflammation, and endothelial dysfunction. Hemodialysis patients are not only exposed to oxidative stress but also to inflammation.

Objective: To investigate the protective effect of instant coffee (IC) on acute liver injury induced by CCl(4).

Methods: The study included 32 rats which were allocated to four groups: control (n: 8), CCl(4) (n: 8), CCl(4)+IC (n: 8) and IC (n: 8). Malondialdehyde, which is a lipid peroxidation product, and levels of antioxidant capacity were measured and histopathological data were compared.

Fulminant hepatitis is a rare complication of acute hepatitis A infection. Nevertheless, the seroepidemiology of the infection is rapidly changing with the developing world, rendering more adults susceptible to the infection, in particular with more severe course. We report here fulminant hepatitis A infection with a mortal course during an epidemic period in two siblings.
