|
|
Pulsatile GnRH therapy
|
causes pituitary LH and FSH prdxn to increase
Used for infertility from acquired hypogonadotripic hypogonadism which is assoc.d with significant stress, eating disorders, and excessive exercise. (bc imbalance of LH and FSH production causes suppression of ovarian estrogen production and ovulation, leading to amenorrhea.) |
|

B-hCG is 1500-6500 IU/L and nothing is seen in the intrauterine gestational sac on transabdominal US.
|
|
|
tamoxifen is Tx for which CA and a risk for which CA?

Tx for breast CA
Risk for endometrial CA Bc. it is a selective estrogen receptor modulator (SERM) with mixed agonist/antagonis effects on estrogen receptors. It is an antagonis in the breast and a partial-agonist of estrogen on the endometrium and increases risk of endometrial carcinoma |
|

Central vs. Peripheral precocious puberty
|
Central :
-Caused by activation of hypothalamic-pituitary-ovaria (HPO) axis -presents with >ed FSH and LH -give CT or MRI -Tx with GnRH analog therapy |
Peripheral:
Caused by gonadal or adrenal release of excess sex hormones -Presents with low FSH and LH |
|

|
Possibilities:
-mullerian agenesis (XX) -androgen insensitivity (XY) -5 alpha reductase deficiency (XY) |
|
|
Mullerian agenisis
|
XX genotype
blind ended vagina little or no uterine tissue |
|
|
androgen insensitivity
|
XY
but there is abnormal androgen receptor So, external genitalia develop as female, butmullerian inhibiting factor is still secreted by testes preventing the development of internal female organs |
|
|
5 alpha reductase deficiency
|
XY
can't convert testosterone to more potent DHT have female external genitalia, but show virilization at puberty |
|
|
Plan B
|
Levongestrol
given up to 120 hr (5 days) after unprotected sex |
|
|

masculinization->amenorrhea |
|
|
serous cystadenomas

emergent cesarean section
|
|
|

-giver her corticosteroids |
|
|
what do you do?
palpation of vertex at the fundus: -at 34 weeks -at 37 weeks |
= breech
most breech will self-correct by 37th week so do nothing at 34 weeks - at 37 weeks attempt external cephalic version. if this fails plan for a cesarean |
|
|
These contraceptions are contraindicated in:

|
|
amenorrhea in lactating mother is caused by?
|
high prolactin -> inhibit prdxn of hypothalamic hormone GnRH.
Pulsatile GnRH release from hyothal is necessary for prdxn and release of LH and FSH by ant. pit. LH an FSH are required to induce ovulation. Menses don't occur when ovulation is suppressed. |
|
|

|
|
How to interpret BPP
|
- 8-10 is normal
-but, BPP of 8 with <ed AFI = delivery (fetal compromise likely) - BPP 6 and >37weeks w/o oligo ; consider delivery -BPP 6 and <37weeks w/o oligo, repeat BPP in 24 hr; deliver if not improved -BPP 6 w/ oligo >32 weeks = delivery -BPP 6 w/ oligo <32 = daily monitoring -BPP <or=4 and >26weeks = delivery |

|
|
Uterine rupture:
