*2.1.1 Infections*

Pediatric acute pancreatitis is associated with paramyxovirus or mycoplasma infections. Mumps virus induces parotitis and orchitis in pediatric population and may be complicated by meningoencephalitis or pancreatitis. In the latter case clinical manifestations are represented by usually self-limiting diarrhea and abdominal pain. Mycoplasma infection-related pancreatitis can be distinguished into two types: early onset type and late-onset type following respiratory tract symptoms beginning. This different onset spectrum is due to a direct injury of mycoplasma into the acinar cells in the former type while to an autoantibodies targeting in the latter [2].
