Henoch–Schönlein purpura

P's of HS Purpura:
Palpable Purpura
Pressure (Blanches on pressure)
Pruritis
Pain abdomen and joints
Positive Guaiac sign in faeces
Proteinuria
Prednisolone given in treatment
Platlet count may be raised but not low (DD: ITP)

Sickle Cell Anemia

In SICKle cell anemia (HBS), the abnormality is in the SICKsth position of Beta chain of HB. Valine is present instead of Glutamic acid, i.e. Glutamic acid Goes.
Or remember: Sickle cell anemia is a Genetic Variation - Glutamic is replaced by Valine

Coagulation factors consumed in clot

The factors consumed in clot are 1, 2, 5, 8. You can remember this by imagining a watch showing the time as 12:58 - 1,2,5,8 ; Also imagine CFC (Clotting factors consumed) written on the watch.

Another mnemonic was sent by our reader Mr. Shiva; Shiva just keeps singing 1,2,5,8 what do we appreciate? clots!

Vitamin K dependent factors

To remember the vitamin K dependent factors, try to memorize this picture. They are factors 2, 7, 9, 10. The story behind the picture mnemonic. In year 2K ( = 2000 = factor 2 is K dependant ), a pregnant lady after carrying her child for 9 months, caring all 7 days a week, gave birth to a child. The child grew up, got 10 upon 10 marks.

Blood group

O Negative (O -ve) blood group is universal dONor

BT, CT, PT, PTT

Bleeding time gives Platlet response ( Remember BP )
Clotting time gives idea about Coagulation pathway ( Remember CC )

Also remember the following about Prothrombin Time (PT) and Partial Thromboplastin Time (PTT):
PTT - Intrinsic and common pathway
PT - Extrinsic and common pathway
( Remember this by imagining that Peter is going to take part in a Tea drinking contest. To be IN to the contest Peter must drink two Teas (TT) - PTT gives idea about INtrinsic and common pathway. If Peter drinks only one T, he is OUT = Extrinsic and common pathway represented by PT )
