I want to find all encounters of patients aged 18-34, 35-44, and 45-54 years old with a diagnosis of acute pancreatitis, including the specific ages of 5, 6, 7, 8, 9, and 60 years old, at any time during their medical history, and retrieve the demographic information and diagnosis code from the i2b2 system.
