An elevated TRH in primary hypothyroidism leads to increased prolactin
-

162

Prolactin: secondary amenorrhea

1. Review meds: antipsychotic and antidepressants have antidopamine leads to increased prolactin
2. CT or MRI to r/o pituitary tumor
3. Idiopathic prolactin elevation, treat w/ bromocriptine

163

Pituitary tumor: treatment

- Tumor < 1 cm; give bromocriptine (dopamine agonist)
- Tumor > 1cm; treat surgically

164

Positive progesterone Challenge Test

Any withdrawal bleeding is diagnostic of anovulation
- treat cyclic progesterone to prevent endometrial hyperplasia.
- clomiphene ovulation induction is done if pregnancy is desired

165

Negative progesterone challenge test

Inadequate estrogen or outflow tract obstruction

166

Estrogen-Progesterone Challenge Test

- 3 weeks of oral estrogen followed by 1 week of progesterone

167

Positive Estrogen-Progesterone Challenge Test

Any withdrawal bleeding is diagnostic of inadequate estrogen. Next step is get an FSH level

- decr. FSH (HPA insufficiency). Order brain tumor via CT

168

Secondary amenorrhea:
Positive estrogen-progesterone challenge test + incr. FSH (ovarian failure).

Y chromosome may be cause if pt < 25 yrs. Order a karyotype confirmation

169

Secondary amenorrhea:
positive estrogen-progesterone challenge test + decr. FSH

Hypothalamic-pituitary failure
- Order brain CT/MRI to r/o a tumor.
- Give estrogen-replacement therapy to prevent osteoporosis

170

Secondary amenorrhea:
negative estrogen-progesterone challenge test

Outflow tract obstruction or endometrial scarring (e.g. Asherman syndrome)
- Hysterosalpingogram to ID lesion
- Management: Adhesion lysis followed by estrogen stimulation

171

Premenstrual Tesnsion

- distressing physical, psych, and behaviorial symptpms recurring at same phase of menstrual cycle and disappearing during remainder of cycle

172

Premenstrual Dysphoric Disorder (PMDD)

- more severe, involving major disruptions to daily functioning and relationships

173

- Pituitary adenoma
- Elevated prolactin
- Medication (e.g. antipsychotic meds)

183

PCOS: Diagnostic Tests

- LH:FSH = 3:1
- Mildly elevated testosterone level
- Pelvic U/S shows bilaterally enlarged ovaries w/ multiple subcapsular small follicles and increased stromal echogenecity

184

PCOS: Treatment

- OCPs treats irregular hirsutism and bleedng
- SPIRONOLACTONE - suppresses hair follicles
- CLOMIPHENE CITRATE or HMG treatment of infertility
- METFORMIN enhances ovulation and manages insulin resistance

185

Rapid onset hirsutism and virilization w/o family hx. Next step?

U/S to look for adnexal mass
CT scan to look for adrenal tumor

186

Rapid onset hirsutism and virilization w/o family hx. Likely dx?

Adrenal tumor (elevated DHEAS)
Ovarian tumor (elevated testosterone)

187

Congenital Adrenal Hyperplasia

- gradual onset hirsutism w/o virilization in teens and 20s associated w/ menstrual irregularities and anovulation
- elevated 17-hydroxyprogesterone
- management involved in corticosteroid replacement to stop androgenicity and restore ovulatory cycles

188

- associated w/ autoimmune disease or Y chromosome mosaicism

198

Amenorrhea during menopause

- menses become anovulatory and decrease in 3-5 years period known as perimenopause

199

Hot flashes during menopause

- unpredictable, profuse sweating and heat that occurs in 75% in women
- obese less likely to undergo hot flashes (due to peripheral conversion of androgens to estrone)

200

Reproductive tract during menopause
