Primary Amenorrhea
No Menses by age 13 with no secondary sexual characteristics
or
No menses by 15 with normal growth and secondary sex characteristics
Secondary Amenorrhea
Previous menstrual cycle but now absent for 3 cycles or 6 months
Pregnancy, Weight changes, Hypothyroid, Prolactinoma, drug use, exercise, etc
Endometrial atrophy (Asherman’s syndrome)
Pituitary Dysfunction (Sheehan’s Syndrome)
Premature ovarian failure (FSH >40)
Dx: HCG, FSH, PRL, Thyroid panel, Estrogen ,progesterone
TX: OCP if don’t want to be pregnant
Cyclic progesterone 10mg for 10 days if want to get pregnant
Physiologic Amenorrhea
Seen prepubescently, During pregnancy and post menopause
Most common cause of secondary amenorrhea
Pregnancy
Genetic reasons for Primary Amenorrhea
Turners Syndrome
Hypothalamic Pituitary insufficiency
Androgen insensitivity
Anorexia
Mullerian agenesis
Imperforate Hymen
Dysmenorrhea
Uterine pain at time of Menses (primary or secondary)
Painful Menstruation that affects Daily Activities
Primary - Due to increased prostaglandins
Secondary - Due to pelvic uterus pathology
Recurrent Crampy Midline Lower Abdominal pain 1-2 days before menses starts
Lasts 12-72 hours
Normal exam
Tx: Supportive care, heat etc,
NSAIDS and hormone therapy
Laparoscopy
Dysfunctional uterine Bleeding (Abnormal Uterine Bleeding)
Unexplained bleeding in nonpregnant women
Normal Exam
No specific test - HCG, H&H, etc.
Endometrial biopsy to rule out cancer in >35 with obesity, hypertension or DM
Biopsy for all postmenopausal women
Causes = PALM COEIN
Acute hemorrhage = IV high dose estrogen or high dose OCP
Chronic management = Estrogen progestin OCP First line
Progesterone if Estrogen is contraindicated
Levonorgestrel IUD
NSAIDS if hormones are unwanted
Surgery (hysterectomy is definitive), Can do endometrial ablation
PALM COEIN
Polyp
Adenomyosis
Leiomyoma
Malignancy or hyperplasia
Coagulopathy
Ovulatory Dysfunction
Endometrial
Iatrogenic
Not Classified
Menopause
Cessation of Menses over 12 months
FSH >30 (not necessary for diagnosis)
Over 40 with no pathologic cause
If under 40 (Premature ovarian failure)
Average 51 years
Hot flashes, Night Sweats, dyspareunia, vaginal dryness Classic symptoms
Tx:
If uterus = HRT (Estrogen+ Progesterone)
If No uterus = Estrogen
HRT can cause increased risk of MI, DVT, CVD, Breast Cx, increased TGL
Unopposed estrogen Risk
Endometrial cancer
Normal Cycle Physiology Phases
2 phases
Follicular Phase (proliferative)
Day 0 to day 14
Luteal Phase (Secretory)
day 15 to day 28
Normal Physiology Phases
Follicular Phase
First part of menstrual cycle, day 0 - day 15
First, GNRH (from hypothalamus) stimulates FSH and LH release (anterior pituitary)
A follicle grows, secreting estrogen
Estrogen initially gives negative feedback
Once estrogen levels are high enough from follicle secretion, it begins to give positive feedback on FSH and LH which then surge
Estrogen secretion is increased even more from the follicle,
It induces an LH spike which causes ovulation
Normal Physiology Phases
Luteal Phase
Typically the luteal phase is days 15-28 of the cycle
After ovulation, the follicle becomes the corpus luteum which secrets progesterone and provides negative feedback to FSH and LH
If pregnancy does not occur, the corpus albicans is formed which no longer secretes estrogen or progesterone.
This decrease in hormones leads to endometrial sloughing or menses
To begin a new follicular phase of the menstrual cycle, GNRH is secreted and cycle restarts
Normal Physiology of Menstrual cycle
Average 28 day cycle
Can be from 20-35 days
2 phases (Follicular and Luteal)
Cycle begins on first day of bleeding (Menstruation) (day one of cycle)
Ovulation or release of the oocyte from ovary begins 14 days before first menstruation (day 14 of average cycle)
Fertilization chance is highest between day 11 and 15 of average cycle
Premenstrual Dysphoric Disorder
Repeated episodes of significant depression and similar symptoms in the week before menstruation
(Occur during Luteal Phase and resolve with menstruation)
Tx SSRI (Fluoxetine, Sertraline)
Can be use symptomatically or regularly
Others: Benzos, TCAs, Clomipramine, Birth Control, Diuretics, Low dose estrogen, GNRH
Ovariectomy for severe refractory cases
Premenstrual Syndrome
Caused by an imbalance of estrogen and progesterone along with excess prostaglandin production
1-2 weeks before menses (Luteal Phase)
Resolve with menses
Bloating, breast tenderness, HA, edema,
irritability,Depression, Anger, Anxiety, Social withdrawal, Confusion (disruption in function)
Tx: Exercise and stress reduction are beneficial
decrease caffeine, NSAIDS
SSRI are first Line
Combined OCP
GNRH agonist
Surgery (bilateral oophorectomy/salpingo oophorectomy is last resort
does not hinder life
Cervicitis
Infection of the cervix, usually from STD.
Inflammation of Cervix from Allergy, spermicide or chemical exposure
Gonorrhea
Chlamydia
Herpes Simplex
Human Papillomavirus (HPV)
Trichomoniasis
Tx:
Infection: Proper ABX
Inflammation: remove offending agent
Gonorrhea
N
Lactational Masitis
First line is NSAIDS (Ibuprofen)
Continue breast feeding
Cool Compress
If not improvement ABX (dicloxacillin or cephalexin)
Consider MRSA coverage (Bactrim, Clinda, Vanco)
PCOS US
String of pearls
Polycystic Ovary Syndrome (PCOS)
Amenorrhea, obesity or overweight, hirsutism
PE will show bilateral ovarian enlargement, acanthosis nigricans
Labs will show high LH to FSH, androgen excess
Most commonly caused by insulin resistance
Treatment is combination oral contraceptive pills, lifestyle
changes, metformin
Most common cause of infertility
Endometriosis
Patient presents with pre- or mid-cycle dysmenorrhea, dyspareunia, dyschezia (painful bowel movement)
PE may show uterosacral nodularity or a fixed or retroverted uterus or adnexal mass
Definitive diagnosis is made by laparoscopy
Most common site is ovaries

Screening Glucose tolerance test
Diagnostic criteria for the 100-gram three-hour GTT to diagnose gestational diabetes:
100-gram oral glucose load is given in the morning to a patient who has fasted overnight for at least 8 hours.
Glucose concentration greater than or equal
to these values at two or more time points is generally considered a positive test
100 gram load
Fasting 95
1 hour 180
2 hour 155
