25
LH surge
peak 10-12 hrs before ovulation
26
Ovulation
PGE and proteolytic enzymes break down follicular wall; occurs 32-44 hrs after beginning of LH surge; Maximal prdxn of spinnbarkeit;; increase of basal body temp 0.2-0.5 F
27
spinnebarkeit
refers to ability of cervical mucus to be stretched between examining fingers; increased stretch = increased influence of estrogen
28
Luteal phase: corpus luteum
formed from ruptured follicle | Secretes progesterone - peak 7-8 days postovulation
29
Proliferative phase of uterine cycle
estrogen influence endometrium grows/thickens lasts approximately 10 days from end of menses to ovulation
30
Secretory phase of uterine cycle
progesterone influence Av 12-16 days Endometrial hypertrophy Increased vascularity
31
Menstruation - of uterine cycle
declining progesterone from CL | endometrium undergoes involution, necrosis, sloughing (3-6 days)
32
screening mammography
``` Age 40-50: ACS: annual; NCI: q 1-2 yrs strong fam hx = earlier/more frequently >50 yr: annually 10-15% false negative rate for detection of malignancies ```
33
BRCA1/2
5-10% br CA is hereditary mutated BRCA1 gene = 80% risk br CA by age 65 Test if strong fam hx or Ashkenaxi Jew
34
Climacteric/perimenopause
used to describe the physiologic changes associated with the change from reproductive to nonreproductive status 2-8 yrs before menopause until 1 yr after last period Rhythmic ovarian/endometrial responses of menstrual cycle decline/eventually stop; # responsive follicles decr with resultant decr prdxn estradiol throughout climacteric. Decr estradiol = incr FSH. End of clim, ovary contains no follicles & endometrium atrophies = reproductive capabilities terminated
35
premature menopause
premature ovarian failure | cessation of menses before age 40
36
menopause
after menopause, LH & FSH both increased | Generally rely on cessation of menses, hypoestrogenic sx, age and consistently elevated FSH for dx of menopause
37
Lab findings of menopause
FSH: >40 mIU/mL LH: 3-fold elevation (20-100 mIU/mL) estradiol: <20 pg/mL
38
vaginal pH in climacteric
pH 5.0 or more
39
Some vaginal sx of climacteric
may have pruritis, leukorrhea, friability, increased susceptibility to infectino, dyspareunia
40
Urinary tract changes with climacteric
Decreased muscle tone: urethra/trigone area Atrophic changes in urethra/periurethral tissue = stress incontinence may occur Hypoestrogenic effects in trigone area; lowered sensory threshold to void = sensory urge incontinence may occur Urinary urgency, frequency, dysuria d/t atrophic changes in urethra and periurethral tissue
41
Vasomotor sx of climacteric: hot flashes
75% of women get them | generally cease w/i 2-3 yrs after menopause
42
CV effects of climcateric
Lipid levels: | incr in LDL (ideal 60)
43
Cognitive fxn in menopause
memory impairment may be indirectly r/t decr estrogen secondary to hot flashes and sleep disturbance Rish of demetia incr in healthy women 65-79 yr using ET or EPT
44
screening for cholesterol and HDL
Age 20: | Q 5 yrs
45
screening for plasma glucose
``` Age 45 (& younger women with risk factors): q 3 yrs ```
46
Thyroid function/TSH screening
Age 65: q 3-5 yrs begin earlier if presence of autoimmune condition or strong family hx of thyroid dz
47
hearing screening
Age 65 & older
48
screening for visual acuity/glaucoma by opthalmologist
Age 40-64: q 2-4 yrs Age 65+: q 1-2 yrs
49
Contraception >40yr
COC: safe for healthy, non-smoking, non-obese perimenopausal women. Non-contraceptive benefits may be esp attractive: relief of vasomotor sx, menstrual regulation POP also safe option IUD: good option, LNG may help with heavy bleeding Barrier methods acceptable Sterilization: most prevalent method in US among married women Fertility awareness less effective during perimenopause with irregular cycles
50
Deciding when to stop contraception
Reaching age 55 (90% have reached menopause by then) vs 2 FSH levels while off hormonal contraceptives and using a nonhormonal contraceptive
51
HT Indications
relief of menopausal sx r/t estrogen deficiency: vasomotor instability, vulvar/vaginal atrophy Prevention of osteoporosis Potential reduction of risk for colon CA
52
C/I to HRT
``` thrmoboemobolic disorders or thrombophlebitis Known or suspected creast cancer Estrogen dependent CA Liver dysfunction or dz Undiagnosed abnormal uterine bleeding Known or suspected pregnancy ```
53
Potential risks of HRT
endometrial hyperplasia/CA Breast CA (relationship w HT inconclusive; possilbe small but signif incr witih long-term HRT) Gallbladder dz Thromboembolic disorders
54
Followup after HT initiation
Reevaluate in 3 months; if no problems, annually after that Evaluate sx each time; discontinue as appropriate Consider nonhormonal drugs for osteoporosis prevention if longterm therapy needed
55
HT regimen options
0.625 mg conjugated E or equivalent prevents osteoporosis in 90% menopausal women 10-14 days q month: 10 mg of MPA or equiv or daily doses of 2.5-5.0 mg for prevention of endometrial hyperplasia Continuous combined: E/P daily (may have unpredictable bldg for a while before amenorrhea) Continuous cyclic: E daily, P for 10-14 days/mo; withdrawal bleed when P done Cyclic: E days 1-25; P last 10-14 days; then 3-6 days of nothing
56
S/E oral estrogen:
increased HDL/triglycerides; | first-pass metabolism determines results
57
effects E/EP patch
no significant impact on HDL/triglycerides; | may have less adverse effects on gallbladder and coagulation factors than oral E
58
Vaginal estrogen creams
tx vulvar/vaginal atrophy; will NOT provide relief from vasomotor sx; some systemic absorption NEED cyclic progestin with intact uterus
59
Estring
little/no systemic absorption; 90 days duration Do not need cyclic progestin
60
Femring
SYSTEMIC absorption tx vasomotor & vulvar/vaginal atrophy 90 day duration Requires added progestin if intact uterus
61
Topical sprays/gels/emulsions (17B-estradiol)
SYSTEMIC absorption NO sig effect on HDL/triglycerides May have less adverse effects on gallbladder and coag factors tahn oral E Need cyclic progestin with intact uterus Topical may not provide sufficient endometrial protection
62
Progestin-only HRT
effective in relieving vasomotor sx May have +impact on Ca balance NOT effective on vulvovaginal sx MAY have adverse effect on lipid profile
63
Testosterone in HRT | oral/transdermal/injections/subQ
may use if E not effective enough on extreme vasomotor sx may incr energy level, feeling of well-being, libido S/e: acne, hirsutism, clitoromegaly Does not appear to have neg lipid effect
64
S/E of HRT
breast tenderness (E/P; usually only few weeks) Nausea (E; relieved if taken AC/HS) Skin irritation w patch Fluid retention/bloating (E/P) Alterations in mood (E/P) TX of S/E: lower dose, dif route, dif formulation
65
Bleeding on HT
Continuous cyclic: usually some bleeding; starts last few days P or just after. If bldg is earlier/heavy/persistent may indicate endometrial hyperplasia = eval Continuous-combined: erratic spotting and light bldg 1-5 days in first yr; endometrial biopsy if heavier or longer than usual
66
Nonhormonal mgmt of vasomotor sx
Antidepressants (ssri, srni) gabapentin, clonidine Avoid caffeine, alcohol, cigarettes, spicy foods, big meals Regular, mod exercise Vit E - anecdotal reports of relief Soy foods, isoflavine supplements
67
