Associations 6 Flashcards
Precocious puberty
<9 (males)
Tanner level 5 (girls)
Breast: areola recedes to level of breast
Pubic hair: spreads to medial thighs
LH in menstrual cycle
Midcycle surge (induced by estrogen) induces ovulation Stimulates corpus luteum to secrete progesterone (luteal phase)
FSH in menstrual cycle
Stimulates development of ovarian follicle (follicular phase)
Estrogens in menstrual cycle
Stimulates endometrial proliferation (follicular phase)
Secreted by follicle, aids follicle growth
Induces LH surge
High levels inhibit FSH secretion
Progesterone in menstrual cycle
Secreted by corpus luteum (luteal phase); *decrease in levels leads to menstruation
Stimulates endometrial gland development
Inhibits uterine contraction, increases cervical mucus thickness
Increases basal body temperature
Inhibits LH and FSH secretion, maintains pregnancy
hCG in menstrual cycle
Acts like LH after implantation of fertilized egg
Maintains corpus luteum viability and progesterone secretion (no menstruation)
Causes of pseudoprecocious puberty
Exogenous hormones (estrogens)
Adrenal tumor
Other hormone-secreting tumor (eg ovarian)
CAH
Phase of menstrual cycle fixed at 14 days regardless of cycle length
Luteal phase
Diagnostic for menopause
Amenorrhea >1 year in woman
Premature menopause
< 40 years old
Hormones in perimenopause
+LH, +FSH
Estrogen fluctuates
Causes primary amenorrhea
HPO axis dysfunction
Anatomic abnormalities (absent uterus, vaginal septa, imperforate hyman, vaginal atresia)
Chromosome abnormalities
Pregnancy
Causes secondary amenorrhea
Pregnancy
Ovarian failure (menopause)
HPO axis dysfunction, uterine abnormalities, PCOS, thyroid disease
Anorexia, malnutrition
Hypogonadism + anosmia
Kallman syndrome
Initial tests for primary amenorrhea
Physical (anatomic abnl)
B-hCG, prolactin, TSH
Signs of hyperandrogenism -> DHEAS, testosterone
Primary amenorrhea + absent uterus on US
Karyotype + serum testosterone
(Androgen insensitivity syndrome = 46XY)
(Abnl mullerian development = 46XX)
Primary amenorrhea + uterus present
B-hCG + FSH
(Pregnancy = high B-hCG)
(Turner syndrome = high FSH)
(HPO axis disease = low FSH)
Secondary amenorrhea initial tests
B-hCG (always first test)
Prolactin, TSH, FSH
If hyperandrogenism signs -> DHEAS, testosterone
Secondary amenorrhea w/ normal initial tests
Progesterone challenge (normal = anovulation) (abnl = low estrogen or outflow tract abnl) If abnl, progesterone-estrogen challenge (normal = HPO axis abnl, menopause) (abnl = outflow tract obstruction eg Asherman syndrome)
Causes secondary dysmenorrhea
Endometriosis, PID, uterine fibroids, ovarian cysts, adenomyosis
Timing primary vs secondary dysmenorrhea
Primary - beginning of menstruation and resolve over several days
Secondary - midcycle before onset of menstruation and increase in severity until conclusion of menstruation
βPowder-burnβ lesions or chocolate cysts on biopsy
Endometriosis
Common symptoms of endometriosis
3Ds - dysmenorrhea, deep dyspareunia, dyschezia
Common causes abnormal uterine bleeding

Regular, heavy abnl uterine bleeding
Think fibroid, adenomyosis, polyp
Irregular, heavy abnl uterine bleeding
Think anovulation
MCC abnormal uterine bleeding
Anovulation
Abnl uterine bleeding related to sex
Think cervical polyp/glandular tissue
Abnl uterine bleeding + positive B-hCG + intrauterine pregnancy + closed cervical os
Threatened abortion
Abnl uterine bleeding + enlarged uterus + menometrorrhagia for months
Fibroids, molar pregnancy, adenomyosis
Abnl uterine bleeding + severe menstrual pelvic pain
Endometriosis, adenomyosis
Menorrhagia + perimenopausal
R/o endometrial hyperplasia / cancer
Abnl uterine bleeding that started w/ menarch
R/o coagulopathy
MC coagulopathy associated w/ abnormal uterine bleeding
Von Willebrand disease
Abnl uterine bleeding + positive B-hCG + no fetus in uterus on US
Ectopic pregnancy
Abnl uterine bleeding + depression + constipation
Hypothyroidism
Diagnostic criteria for PCOS
2/3
Oligo or anovulation
Androgen excess
Polycystic ovaries (βstring of pearlsβ) by US
Labs for PCOS
+LH
LH:FSH ratio >2:1
+DHEA, androstenedione, testosterone
+progesterone challenge (anovulatory)
Complications of PCOS
Infertility
DM
Endometrial cancer (+unopposed estrogen)
Also HTN, ischemic heart disease, ovarian torsion
βDew drops on rose petalsβ rash
Varicella zoster (chicken pox)
MCC postmenopausal bleeding
