Background: To assess the economic aspects of HBV (hepatitis B virus) transmission prevention for premarriage individuals in a country with cultural backgrounds like Iran and intermediate endemicity of HBV infection. Materials and methods: A cost-effectiveness analysis model was used from the health care system and society perspectives. The effectiveness was defined as the number of chronic HB...
Introduction: Bile duct obstruction due to gall stone is the most common cause of biliary infection. Bacteria stabilize during the inflammation of gallbladder and it is confirmed that longer duration of inflammation is associated with more risk of post operative infection. In this study we sought to determine the biliary microbial flora in patients with acute and chronic cholecystitis in orde...
Background & Aims: Gastritis is an inflammation of the stomach, and has many possible causes. The major etiologic association of chronic gastritis is chronic infection by Helicobacter pylori (H.pylori) and that may act as a risk factor for proteins, lipids and DNA damages. The aim of this study was to investigate effects of Helicobacter Pylori infection on malondialdehyde, reduced glutathio...
Background and Objective: Long period risk of gastric carcinoma in people affected with chronic Helicobacter pylori gastritis is 5 times more than normal people. Perhaps histological changes due to helicobacter pylori infection could be used for screening people at risk of gastric carcinoma and peptic ulcer. Materials and Methods: This study has been carried out as a cross...
Objective(s): Hepatitis B virus infection causes chronic disease such as cirrhosis and hepatocellular carcinoma. The metabolomics investigations have been demonstrated to be related to pathophysiologic mechanisms in many disorders such as hepatitis B infection. The aim of this study was to investigate the saliva metabolic profile of patients with chronic hepatitis B in...
hepatitis b is the most common cause of acute and chronic viral hepatitis in iran. it is the etiology of 70% of end-stage liver disease and hepatocellular carcinoma in the country. before the universal neonatal vaccination in iran (1992), the contact rate with hbv was about 30% and the hbs ag+ rate was about 3%. in 2009 the contact rate has declined to 18% and hbsag+ rate decreased to 2%. the e...
pulmonary agenesis is a very rare condition and many of them are associated with a variety of cardiac and non-cardiac malformations. we report an eight-month old girl with chronic lung infection due to right sided pulmonary agenesis without any associated major cardiac or non-cardiac abnormalities. the case brings in forth the importance of investigating any infant presenting with features of c...
OBJECTIVE The association between chronic hepatitis virus infection and rheumatoid arthritis (RA) remains debatable. This nationwide population-based cohort study assessed the risk of RA among patients with a chronic infection of hepatitis B and/or C virus. MATERIALS AND METHODS We used data extracted from the claims of 1,000,000 randomly sampled individuals covered under the Taiwan National ...
