A. 80 percent of porcelain gall bladder predispose to malignancy
B. Untreated advanced CA GB median survival is 2-5 months
C. Stippled calcification of mucosa has higher risk of malignancy than diffuse intramural calcification
D. More than 75 percent of CA gall bladder has history of cholelithiasis
69% to 86% of patients with gallbladder cancer have a personal history of gallstone disease.
The presence of an abnormal pancreaticobiliary duct junction, thought to promote chronic biliary inflammation, has been associated with both choledochal cyst disease and gallbladder cancer.
In porcelain gallbladder, risk of ca gb due to chronic inflammation and calcification of the gallbladder wall, was once estimated to be as high as 61%; however, more contemporary analyses suggest that the correct figure is more likely between 7% and 25%

ans b) 10 raise to the power 5
Prerequisites for skin grafting: The recipient site should be assessed for potential bacterial load, blood supply, presence of devitalized tissue, and exposed vital structures. Donor site availability Perform recipient site tissue culture if history or concern for infection (counts <105 CFU/g tissue for most pathogens required before grafting). Presence of group a beta heamolytic streptococci is absolute contraindication for skin grafting [/bg_collapse]
