The aim of this study is to determine the origin, clinical outcome, allograft histological characteristics, and virological outcome of de novo hepatitis B virus (HBV) infection after orthotopic liver transplantation (OLT). We studied 136 hepatitis B surface antigen (HBsAg)-negative liver transplant recipients. HBV DNA was detected by dot-blot hybridization(More)
OBJECTIVES To assess the prevalence and significance of HCV infection in patients with chronic active hepatitis B. METHODS We studied clinical and histological activity in 132 patients with chronic active hepatitis B, 17 of whom were co-infected by HCV. Serum HBV-DNA was determined by dot-blot hybridization and polymerase chain reaction (PCR) and serum(More)
OBJECTIVES Factors that determine the severity of hepatitis C virus (HCV)-recurrent disease in patients undergoing orthotopic liver transplantation (OLT) for HCV cirrhosis have not been clearly identified. To address this issue, we evaluated the histological and virological outcome in 25 patients who underwent OLT for HCV cirrhosis. METHODS HCV-RNA was(More)
Natural killer (NK) cell activity against K562 cell line, and interleukin-2 (IL-2) activity in supernatants from lectin-activated PBMC cultures from 17 patients with acute hepatitis B in the early phase of illness were studied. These patients showed enhanced NK cytotoxicity and higher levels of IL2 activity as compared with control subjects. There was a(More)
We studied a 62 year-old woman with a clinical phenotype characterized by encephalopathy, restrictive cardiomyopathy, and prominent intestinal pseudo-obstruction. Muscle morphology showed ragged red fibres with ultrastructurally abnormal mitochondrial whereas muscle respiratory chain was normal. Molecular genetics revealed the 'common deletion' in mtDNA,(More)
PURPOSE To report a patient with Achromobacter xylosoxidansendophthalmitis that was diagnosed using polymerase chain reaction and gene sequencing. METHODS Case report. A patient with culture-negative endophthalmitis underwent an anterior chamber tap. Polymerase chain reaction was performed on the aqueous sample using the 16S ribosomal DNA primer set to(More)
The clinical course, changes in liver function tests and the behaviour of viral markers over the course of time have been examined in 45 patients with acute hepatitis B and 14 patients with acute hepatitis caused by B and D viruses coinfection. There were no significant differences either in the clinical course or in the liver function tests, in the two(More)
Recently in Mexico the number of cosmetic surgeries has increased. These procedures are often carried out by unqualified people using obsolete and contraindicated products such as injectable oil, which cause uncorrectable disfigurement or more serious complications, even death, after reaching the systemic circulation. We report the case of a fat embolism(More)
