ABSTRACT
A 42 year old man presented with obstructive jaundice and cholangits. Ultrasonography (USG) revealed dilated intrahepatic biliary radicals and common bile duct (CBD). The bile duct also showed a curvilinear parallel intraluminal structure suggesting biliary ascariasis. The CBD was explored and a dead worm removed but jaundice persisted. Endoscopic retrograde cholangio pancreaticography (ERCP) was done showing a periampullary mass which on biopsy showed a villous adenoma with highly dysplastic changes. A Whipple's pancreaticoduodenectomy was performed and the growth proved to be a well differentiated periampullary adenocarcinoma.

Susceptibility and/or immune response to tuberculosis may or may not be associated with particular histocompatibility leucocyte antigen (HLA) phenotype frequencies. The present study was undertaken to north eastern Indian population to verify any association between HLA phenotypes and immune response to mycobacterial antigen. HLA-typing was done in 60 well Tarasaki trays and T-cell subsets in each group were measured using Ficoll-hypaque nylon wool columns and dynabeads (M-450). No universal association with particular HLA-type and pulmonary tuberculosis has been confirmed.
