Hepatitis G virus exposure in dialysis staff.

Hepatitis G virus (HGV) is a blood-borne virus. Some present data demonstrate an occupational risk of HGV infection in medical staff of dialysis units. The aim of this investigation was to assess the prevalence of HGV exposure in dialysis staff.

Hepatitis G virus exposure in dialysis patients.

Background: Hepatitis G virus (HGV) is a blood-borne virus. The predominant route of its transmission is parenteral. The aim of this study was to assess the frequency of HGV exposure in haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients in Iran.

Prospective evaluation of endoscopic ultrasonography in the diagnosis of biliary microlithiasis in patients with normal transabdominal ultrasonography.

Prior investigators have proposed microlithiasis as a causative factor for occult gallbladder diseases. Endoscopic ultrasonography (EUS) is potentially far more sensitive than transabdominal ultrasonography (TUS) in visualizing small stones. The aim of this study was to investigate the role of endoscopic ultrasonography (EUS) in the diagnosis of microlithiasis in patients with upper abdominal pain and normal TUS.
