Single nucleotide polymorphisms on gene among Filipinos and its association with post-operative pain relief via COX-2 inhibitors.

gene encodes an enzyme involved in the metabolism of a wide variety of drugs which include celecoxib. This study investigated the frequencies of the alleles and genotypes of , , and among Filipinos who underwent surgery, and to determine the association of polymorphisms with post-operative pain relief via COX-2 inhibitors. Response to celecoxib was determined using the numerical rating scale (0-10) on the 24th and 48th hour of surgery.

Association of hepatitis B genotypes with clinical profile of patients with chronic hepatitis B.

Hepatitis B virus (HBV) infection is a common cause of chronic liver disease and is responsible for HBV-related deaths due to cirrhosis and HCC. It is well recognized that viral genotypes play an important role on the outcome of HBV infection. Ten HBV genotypes have been identified and the prevalence varies geographically.

Hepatic steatosis in chronic hepatitis B: a study of metabolic and genetic factors.

Hepatic steatosis is a common finding in liver biopsy and may co-exist with chronic hepatitis B (CHB) infection. The aims of this study were to determine the prevalence of steatosis in CHB patients among Filipinos; determine the factors related to the presence of steatosis among individuals with and without CHB infection; and to investigate the possible association between steatosis and polymorphism in interleukin 28B (IL28B) gene. The presence of steatosis was correlated with clinical, biochemical and histological parameters.

Untypable genotype restriction patterns and surface gene variants of hepatitis B virus isolates.

Chronic hepatitis B is a global health problem, and is one of the leading causes of cirrhosis and hepatocellular carcinoma. Hepatitis B virus (HBV) genotyping helps in decision making for clinical management of HBV infection, and is important for epidemiological studies. The objectives of this study were to investigate the distribution of HBV genotypes circulating in the Philippines; molecularly characterize untypable genotype restriction patterns; and analyze the presence of surface gene variants.

Frequency of interleukin 28B rs12979860 C>T variants in Filipino patients chronically infected with hepatitis B virus.

Hepatitis B virus (HBV) is one of the most prevalent viral infections worldwide. Nearly 400 million individuals are chronic carriers of HBV. The aim of the present study was to determine the frequency of human interleukin 28B (IL28B) variants among treatment naive Filipino patients clinically diagnosed with chronic hepatitis B (CHB), and to compare the IL28B frequency distribution with various ethnic populations.

A novel technique of single patch repair of right partial anomalous pulmonary venous return to the superior vena cava by right atrial edge rotation.

In patients with partial anomalous pulmonary venous return of the right superior pulmonary veins to the superior vena cava, surgical repair generally consists of either intraatrial baffle with or without caval enlargement, or superior caval transection and cavoatrial anastomosis to the right atrial appendage. We discuss here a novel technique of superior caval enlargement without need for patch material or reimplantation.
