Background: While prevalence of Hepatitis B virus (HBV) in patients with end-stage renal failure (ESRF) who are undergoing dialysis has decreased significantly during the past few decades, it still remains a distinct clinical problem. The immunosuppressive nature of renal disease often leads to chronicity of the HBV infection and an opportunity for nosocomial spread of the infection among dialysis patients. Egypt is among the countries with intermediate endemicity of HBsAg (range, 2%-7%). Large-scale geographic heterogeneity in HBV prevalence has been reported worldwide and HBV prevalence is especially heterogeneous in Egypt. Objectives: To assess the prevalence of occult HBV infection (OBI) in hemodialysis patients with or without chronic hepatitis C (HCV) from Minia and Assuit, Upper Egypt, using HBV DNA assays. Patient and Methods: Sera from 145 hemodialysis patients with negative HbsAg were investigated for HBV DNA using real-time polymerase chain reaction (RT-PCR). Only serum samples with repeatedly detectable HBV DNA were considered positive. Patients were divided into 2 groups: HCV RNA positive and HCV RNA negative, based on the results of a third generation enzyme linked immunosorbent assay (ELISA) anti-HCV test and HCV RNA PCR. Results: HBV DNA was detected in 6 of the 145 patients (4.1%) and HBcAb was detected in 29/145 patients (20%). There were no statistically significant differences in the age, duration of hemodialysis, biochemical parameters, serological markers of HBV, or HBV DNA between patients with and without HCV infection. Conclusions: Four percent of the hemodialysis patients had OBI. There was no significant difference in the prevalence of OBI between hemodialysis patients with or without HCV co-infection.

Abstractactually scant. This study aimed to correlate the diagnostic accuracy of ultrasonography with electrodiagnosis in both DM and non-DM CTS patients. Patients and Methods: Thirty six non-diabetic patients and twenty five diabetic patients with CTS were assessed. All patients were subjected to electrophysiological assessment of wrists and grayscale ultrasonography (US).Results: High mean cross sectional area of median nerve (CSA) on ultrasonography was detected with nonsignificant difference between both groups. A non-significant difference for flattening ratio was found between two groups. There was a highly significant positive correlation between electrodiagnosis and ultrasonography in diabetic patients. Conclusion:The CSA of median nerve is larger in CTS hands in both DM and non-DM patients. The combination of electrophysiology and ultrasonography provides diagnostic effective tools across the entire spectrum of CTS in diabetic and non-diabetic patients.
