S Pyogenes Sequlae

Questions about the complications of GAS (S Pyogenes) infection give me headaches.

Here is how the questions have been presented so far:

kid with honey coloured crusty lesion on his face now comes in with blood in urine:

Impetigo complication --> post strep glomerulonephritis. The patient may develop hematuria. 

kid with sore throat now has dancing motions or blood in urine:

Pharyngitis --> Post strep glomerulonephritis and rheumatic fever. 

In summary

rheumatic fever only occurs following infection with strains responsible for pharyngitis!! 

Pencillin only reduces risk of glomerulonephritis, NOT rheumatic fever!
