Background. To evaluate the accuracy and utility of the triangular cord sign and gallbladder length in diagnosing biliary atresia by sonography.¶Materials and methods. Sixty fasted infants with cholestatic jaundice aged 2–12 weeks were examined sonographically using a 5–10 MHz linear array transducer, focusing on the triangular cord sign (as described by(More)
The need for safe and effective vaccines to reduce morbidity and mortality caused by rotavirus gastroenteritis in children is well-known. A live attenuated monovalent rotavirus vaccine (Rotarix) containing human rotavirus strain RIX4414 of G1P1A P[8] specificity is being developed to meet the global need. An overview of RIX4414 trials in developed and(More)
This study evaluates the safety and efficacy against severe rotavirus gastroenteritis of the oral live attenuated human rotavirus vaccine RIX4414 (Rotarix) during the first 2 years of life in Asian infants from high-income countries. Healthy infants were enrolled to receive 2 doses of RIX4414 (N=5,359) or placebo (N=5,349). From 2 weeks post-dose 2 to 2(More)
Objective. To describe the gallbladder ghost triad and evaluate its usefulness in the sonographic diagnosis of extrahepatic biliary atresia (BA). Methods. From October 1997 to February 2002, 217 fasted infants with cholestatic jaundice aged 2–12 weeks were examined sonographically . We defined the gallbladder ghost triad as gallbladder length <1.9 cm, lack(More)
BACKGROUND At present, no rotavirus vaccine is commercially available for use worldwide. Hence, a live, attenuated monovalent vaccine was developed with human strain RIX4414 (G1P1A P[8] specificity). Vaccination trials involving infants are ongoing in developed and developing countries. METHODS This study was a randomized, double-blind, placebo-controlled(More)
INTRODUCTION The world's first rotavirus vaccine, Rotashield or RRV-TV, was registered in the US in 1998, but withdrawn within a year because of an observed association with intussusception (IS). Surveillance for IS has consequently become important in safety monitoring of new-generation rotavirus vaccines during development. Post-marketing surveillance is(More)
In recent years, 99mTechnetium IDA hepatobiliary scintigraphy has been widely accepted as a highly sensitive and fairly accurate test in the diagnosis of biliary atresia and evaluation of neonatal jaundice. Over a period of 4 years from 1982 to 1986, a total of 110 paediatric patients had undergone 99mTechnetium IDA hepatobiliary scans in our department for(More)
RIX4414 (Rotarix™), has shown high efficacy during the first 2-years of life. A 2-year randomized, double-blind, placebo-controlled trial in Singapore, Hong Kong, and Taiwan was extended for another year. Infants (6-17 weeks) received 2-doses (1-2 months apart) of RIX4414 (n=5359) or placebo (n=5349). During the third-year follow-up, 4359 (RIX4414) and 4328(More)
