Q

What is the management of pahtological vaginal discharge?

A
  • Culture to identify causative organisms.
  • Urinanalysis to rule out cystitis.

How are polycystic ovaries diagnosied in the adolescent?

A

Rotterdam Consensus Workshop:

PCOS is a syndrome of ovarian dysfunction along with the cardinal features hyperandrogenism and polycystic ovary morphology

  • No single diagnostic criterion
  • Diagnosis of PCOS made on the basis of two out of three;
    • Oligo- or anovulation
    • Clinical or biochemical sign of hyperandrogenism
    • Polycystic ovaries on USS or direst inspection
  • Other causes of hyperandrogenism should be excluded
