Acute PancreatitisMost Common causes: Gallstones (30-60%)
and Alcohol (15 to 30%)Abdominal pain is the major symptomDiagnosis: increased level of serum amylaseCT scan may confirm the clinical impression
of acute pancreatitis even in the face of normal serum amylase levels

Polycythemia VeraIs a stem cell disorderProminent feature: elevated absolute red
blood cell count because of uncontrolled red blood cell production
Increased white blood cell and platelet production due to an abnormal clone of hematopoietic stem cells with increased sensitivity to different growth factors of maturation

HydroxyureaIs a nonalkylating agent that inhibits DNA
synthesis and cell replication by blocking the enzyme ribonucleotide reductase resulting in a megaloblastic blood picture
Onset of action is rapid, usually 3-5 days of initiation of treatment and effect is short-lived once medication is stopped
Initial dose is 15mg/kg per day, taken in divided doses

Thrombosis in polycythemia veraThrombosis is a frequent complication in
persons with Polycythemia veraResult from the disruption of hemostatic
mechanisms because of increased level of red blood cells and an elevation of platelet count.

of thrombocytosis

HeparinIs an indirect thrombin inhibitor which
complexes with antithrombin converting it from a slow to a rapid inactivator of thrombin.
Limitation: narrow therapeutic window of adequate anticoagualtion without bleeding.
