In this paper we study the dynamics of Hepatitis B virus (HBV) infection under administration of a vaccine and treatment, where the disease is transmitted directly from the parents to the offspring  and also through contact with infective individuals. Stability of the disease-free steady state is investigated. The basic reproductive rate, $R_0$, is derived. The results show that the dynamics of...

endoscopic retrograde cholangiopancreatography (ercp) is widely used for the diagnosis and treatment of biliary and pancreatic tract disease. perforation is a rare complication of it, but it is associated with high rate of mortality, an overall mortality rate of 1.0-1.5%. here, a case of massive subcutaneous emphysema following ercp was reported without an obvious retroperitoneal or peritoneal ...
