Double aortic arch (DAA) is an extremely rare vascular malformation which causes tracheal and esophageal compression, resulting in respiratory symptoms such as stridor and wheezing, or feeding problems such as dysphagia, usually during the first few months of life. In contrast, this disorder is rarely diagnosed in adults. We herein present an elderly case with thoracic esophageal carcinoma with...

BACKGROUND & AIMS Interferon-free direct-acting antiviral (DAA) therapies are effective in patients with hepatitis C virus-induced cryoglobulinemia vasculitis (HCV-CV). We analyzed blood samples from patients with HCV-CV before and after DAA therapy to determine mechanisms of these drugs and their effects on cellular immunity. METHODS We performed a prospective study of 27 consecutive patient...

BACKGROUND AND OBJECTIVES Hepatitis C virus (HCV) variants that confer resistance to direct-acting-antiviral agents (DAA) have been detected by standard sequencing technology in genotype (G) 1 viruses from DAA-naive patients. It has recently been shown that virological response rates are higher and breakthrough rates are lower in G1b infected patients than in G1a infected patients treated with ...

Background.  Access to hepatitis C virus (HCV) medications for human immunodeficiency virus (HIV)-infected patients with ongoing barriers to care is restricted by healthcare payers in the absence of HCV treatment outcomes data in the era of direct-acting antivirals (DAA). Methods.  Retrospective analysis of HCV treatment outcomes using interferon (IFN)-free DAA regimens and an inclusive treatme...

BACKGROUND People who inject drugs (PWID) are disproportionally affected by the hepatitis C virus (HCV) infection. The efficacy of HCV treatment has significantly improved in recent years with the introduction of direct-acting antivirals (DAAs). However, DAAs are more costly than pegylated-interferon and ribavirin (PegIFN/RBV). We aimed to assess the cost-effectiveness of four HCV treatment str...

PURPOSE The clinical and radiological characteristics of the double aortic arch (DAA) and its differentiation from conotruncal malformations (CTM) were reported in order to familiarize pediatric practitioners with these congenital heart diseases. MATERIALS AND METHODS From July 1994 to December 2006, a total of 6 patients (4 male and 2 female, aged 16 days to 6.5 years) with DAA were enrolled...

A pot experiment was conducted in the rabi (post rainy) seasons of 2001 and 2002 to study the genotypic differences in grain growth rate and endogenous hormonal content in the developing grains of hexaploid and tetraploid wheat. The endogenous hormonal contents of grains in both the ploidy levels had changed in sequence. At 5 days after anthesis (DAA), gibberellic acid (GA3); at 15 DAA (rapid g...

conclusions if such a regimen is approved, it would be a breakthrough in the treatment of hcv in subjects with hemoglobinopathy. more prospective, randomized control trial studies are needed to investigate the efficacy and safety profile of such a regimen. case presentation we described a 16- year-old male patient with sickle-thalassemia who was infected with a hcv. treatment was started with s...

The incidence of severe sepsis increases dramatically with advanced age, with a mortality rate that approaches 50%. The main purpose of this investigation was to determine both short- and long-term survival outcomes among 386 patients aged >or=75 years who were enrolled in the Protein C Worldwide Evaluation of Severe Sepsis (PROWESS) trial. Subjects who were treated with drotrecogin alfa (activ...

Chronic hepatitis C virus (HCV) infection has generally been associated with a slightly increased risk of developing hepatocellular carcinoma (HCC). For the past several decades, most patients with chronic HCV cirrhosis have been treated with pegylated interferon and ribavirin therapies, which were known to achieve sustained virologic response (SVR) but also carried their own side effects and t...
