- #### Classical Presentation
- a child afebrile presenting with purpura having a history of fever 2-3 weeks back
- #### Probable Diagnosis
- ### Laboratory Tests

- ## Management and Treatment
background-color:: blue
- ### Medical Treatment
- No symptoms ⇒ No Tx : "observation"
- IVIG (or anti-D immune globulin if Rh+ & DAT+ (positive comb's test))
- Platelet transfusion
- Rituximab, eltrombopag, Romiplostim
- ### Surgical Options
- ### Splenectomy
- not for children | because it is a major immune organ
- vaccinate (pre-op)
- strept pneumo
- H. influenza
- Nisseria meningitidis
- antibodies (post-op)
- advantages (the following functions of spleen are rectified)
- platelets hide within the spleen
- plasma cells in spleen produce ((674736e2-8fe7-4418-85aa-e7de99f38eaa))
- platelets get destroyed by splenic macrophages
