BACKGROUND AND PURPOSE Hepatitis D virus (HDV) is a defective RNA virus dependent on hepatitis B virus (HBV) infection for its replication and expression. It is known that coexistent infection with HDV tends to aggravate the course of HBV-associated liver disease. This study was carried out to determine the seroprevalence of HDV among hepatitis B surface(More)
BACKGROUND/AIMS As hepatitis B and C virus have the same transmission routes, dual infection may occur. The aim of this study was to determine the seroprevalence of HCV in HBsAg-positive subjects. METHODS 139 HBsAg-positive subjects were enrolled in the study. Serum samples were tested using ELISA method for anti-HCV antibodies. Chi-square and Fisher's(More)
The aim of this study was to determine the seroprevalence of HCV in HBsAg positive subjects. In a population based single stage cluster sampling in Golestan province of Iran, 139 HBsAg positive subjects were detected and enrolled in the study. Serum samples were tested using ELISA method for anti-HCV antibodies. Chi-square and Fisher's exact tests were used(More)

OBJECTIVE To compare afternoon serum/plasma levels of hormones in four groups: (A) veterans with posttraumatic stress disorder (PTSD), (B) offspring of PTSD veterans, (C) veterans without PTSD, and (D) offspring of non-PTSD veterans. METHODS Evaluation consisted of a semi-structured interview for axis I and II diagnoses, followed by measurement of(More)
BACKGROUND/AIMS Although a "hospital-based cancer registry" is important in improving patient care, a "population-based cancer registry" with emphasis on epidemiology is important in allocating health care resources and prioritizing public health programs. Because of its reliance on retrieved clinical and para-clinical documents, there is some limitation in(More)
This study was carried out to determine the seroprevalence of hepatitis D virus among HBsAg positive individuals in the northeast part of Iran. One hundred thirty nine HBsAg positive subjects detected from a population based single stage cluster sampling in Golestan province of Iran were enrolled. All cases were evaluated for the presence of anti-HDV(More)
