OBJECTIVE HCV infection has a chronicity rate of about 70%, several studies have shown that interleukin-18 (IL-18) was associated with etiology and progression of hepatitis C virus (HCV) infections. However, the association between single-nucleotide polymorphisms - 607C/A (rs1946518) and - 137G/C (rs187238) located in the IL-18 gene promoter and chronic hepatitis C virus infections was still co...

Allergic contact dermatitis is very common and may be complicated by secondary infections. Chronic lymphoedema is a potentially debilitating condition, which may occur due to secondary infections or the dermatitis itself. The problem of chronic lymphoedema following allergic contact dermatitis has been infrequently reported. We report a case of a 47-year-old woman with severe allergic contact d...

according to the national institutes of health and the center for disease and prevention, it is estimated that 65 to 80 percent of the human infectious are caused by biofilms. antibiotics and drainage of purulent discharge are the main treatment measures. but in chronic infections sometimes these findings are not easy to recognize. biofilm is an extracellular polymeric conglomeration generally ...

BACKGROUND AND PURPOSE Differential diagnosis between malignant tumors and chronic infections in the masticator space remains challenging. The purpose of the study was to categorize various changes of both lesions by using single-voxel 1H-MR spectroscopy. MATERIALS AND METHODS Twenty-four masticator space lesions, 7 chronic infections, and 17 malignant tumors were assessed with 1H-MR spectros...

A large proportion of chronic hepatitis B virus (HBV) infections are acquired during childhood. Fewer chronic hepatitis C virus (HCV) infections occur in children than in adults, but thousands of children worldwide have this serious infection. Optimal treatment strategies for these chronic infections in children have not been determined, because data on the natural history are limited. Few medi...

The role of chronic nontuberculous infections as a cause of human misery and disability has not been adequately appreciated. The Initial, causative factor, primarily seemingly insignificant and justifying scant consideration, may eventually pass through a series of conditions, leading in the end to invalidism and even death. It Is my purpose In this paper briefly to sketch the course of chronic...

common variable immunodeficiency (cvid) is a heterogeneous group of disorders characterized by hypogammaglobulinemia and an increased susceptibility to recurrent infections as well as autoimmunity and malignancies. idiopathic thrombocytopenic purpura (itp) and autoimmune hemolytic anemia (aiha) are two autoimmune disorders which may be seen in association with cvid. among 85 cvid patients, seve...

Urticaria is a group of diseases that share a distinct skin reaction pattern. Triggering of urticaria by infections has been discussed for many years but the exact role and pathogenesis of mast cell activation by infectious processes is unclear. In spontaneous acute urticaria there is no doubt for a causal relationship to infections and all chronic urticaria must have started as acute. Whereas ...

 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

This study investigated the risk factors associated with recent and chronic HIV infections among individual attending a voluntary counseling and testing (VCT) site in Rio de Janeiro, Brazil. In a cross-sectional study, recent HIV infections were detected by the sensitive/less-sensitive test, using Serologic Testing Algorithm for Recent HIV Seroconversion (STARHS) strategy, and compared to chron...
