135
In central precocious puberty, what levels of LH/FSH would you expect? What should you do next?
In central, basal serum concentrations of LH/FSH may be normal Maturity then has to be demonstrated by GnRH stimulation and LH response MRI if central to rule out CNS disorder
136
In peripheral precocious puberty, what levels of LH/FSH would you expect? What should you do next?
In peripheral, LH and FSH are low due to negative feedback response of high gonadal steroid US of ovaries if possible peripheral

What is the tx for precocious puberty in girls? What drug class?
Leuprolide GnRH analog
138
What is the MOA of Leuprolide?
GnRH analog that desensitizes and downregulates pituitary GnRH receptors and thus decrease gonadotropin secretion. Acting as a potent inhibitor of gonadotropin secretion, leuprolide produces an initial increase in luteinizing hormone and follicle stimulating hormone aka it overstimulates the GnRH receptors to the point that they stop listening and shut off
