Goals: To evaluate the effectiveness of psychiatric counseling in reducing the rate of development of psychiatric side effects of antiviral therapy with interferon-α and ribavirin among study participants compared with standard clinical monitoring alone.

Background: Interferon-α is used to treat chronic hepatitis C. Interferons may induce adverse events that usually, but not always, reverse within a few days after the end of therapy.

Non-alcoholic steatohepatitis (NASH) is a progressive fibrotic disease. Many issues related to the pathogenesis of this disease remain unresolved. Because of NASH association with the activation of liver fibrogenesis, we examined the plasma levels and liver immunolocalization of matrix metalloprotease-9 (MMP-9), a molecule involved in the remodelling processes of fibrogenesis.

Background: The role played by the immune system in the progression of chronic hepatitis C (CHC) is not completely clear. Opioids may facilitate the outbreak of infections through marked immunomodulating effects on the immune response against a virus. To asses if addicts can be treated successfully with interferon (IFN) during detoxification treatment, we evaluated some immune response mediators in addicts affected by CHC.

To assess whether pathogenic endothelial dysfunction is involved in acute idiopathic tinnitus we enrolled 44 patients and 25 healthy volunteers. In blood from the internal jugular vein and brachial vein we determined malonaldehyde, 4-hydroxynonenal, myeloperoxidase, glutathione peroxidase, nitric oxide, L-arginine and L-ornitine, thrombomodulin (TM) and von Willebrand factor (vWF) activity during tinnitus and asymptomatic period. Higher plasma concentrations of oxidative markers and L-arginine, and lower nitric oxide and L-ornitine levels were observed in jugular blood of patients with tinnitus, there being a significant difference between brachial and jugular veins.

Background: Increased generation of reactive oxygen species (ROS) and oxidative stress may be of crucial importance in the pathogenesis of endothelial damage. Furthermore, there is understood to be a relationship between endothelial damage, glycemic control, disorders of lipid metabolism, and coagulative hemostatic disorders.

Objective: This study investigated within- and between-group changes in various circulating markers of oxidation-reduction balance and endothelial function after a balanced moderate-fat meal with and without antioxidant supplementation in patients with early-stage, untreated type 2 diabetes mellitus; subjects with impaired glucose tolerance (IGT); and healthy controls.

PURPOSE: Only early detection of non-symptomatic patients is able to arrest the diffusion of the non-symptomatic HCV infection and lead to prompt treatment. Our aim was to attempt to correlate the presence of perihepatic lymph nodes and hepatitis C infection and to assess whether ultrasonography can have a role to promote specific investigations for pre-clinical diagnosis of virus C infection. METHOD: We performed a controlled study on a cohort of 7974 subjects from a town of 27000 inhabitants on the eastern coast of Sicily.

Background: Chronic infection with hepatitis C virus (HCV) is the most common infectious disease among heroin abusers, but it is recommended that specific treatment with interferon be delayed until at least 6 to 12 months after the end of drug addiction.

Objective: We investigated the response of heroin abusers to interferon treatment shortly after the end of detoxification treatment with methadone.

Methods: We studied 2 homogeneous groups of white Italian patients with chronic HCV infection: former male heroin abusers and males without a history of drug addiction.

Laser therapy has gained wide acceptance and application in many medical disciplines. Side effects of laser therapy are rare and the most frequent mainly involve the skin. We describe a patient affected by familial adenomatous polyposis that had been repeatedly controlled and treated endoscopically using an Nd:Yag laser.
