Gyn Flashcards
Name most common etiologic causes of 2e amenorrhea (2)
- Ovarian causes—40%
- Hypothalamic causes—35%
Describe tx: Primary Ovarian Insufficiency (3)
- Patient education (diagnosis)
- Hormone replacement therapy until age of menopause
- Maintain age-appropriate bone density
- Cardiovascular health
- Yearly F/U of HRT, TSH levels; bone scan as needed
Describe tx: Primary dysmenorrhea (3)
- NSAIDs
- Hormonal suppression (OCPs, Depo-Provera, Mirena)
- Nonpharmacologic (i.e., physical exercise, topical heat, high- frequency transcutaneous electrical nerve stimulation (TENS))
Describe steps for primary amenorrhea (3)
- B-hcg
- Pelvic ultrasound
- Serum levels of FSH
In amenorrhea, if present + high FSH, think of what? (2)
- Gonadal dysgenesis: Turner Syndrome, Swyer syndrome
- 17 alpha hydroxylase deficiency
Describe: Gonadal dysgenesis (3)
- Present streak gonads, functionless, fribrous tissue, can’t respond to FSH stimulation
- Can’t produce sex hormones -> no 2e female sex characteristics
- Associated with Turner’s syndrome and Swyer syndrome
How to dx: Turner’s syndrome
- Karyotype: 45X or Mosaic (45X + 46XX OR 45X + 46XY)
Describe presentation: Turner’s syndrome (6)
- Short stature
- Widely spaced nipples
- Low-set ears
- Wide or webbed neck
- Broad chest
- Arms turn outward
Describe tx: Turner’s syndrome (3)
- Streak gonads surgically removed
- Estrogen therapy (low doses) + progesterone (2 yrs after) 10 days per month to induce menstrual bleeding
- Growth hormone therapy
Describe lab: 17 alpha hydroxylase defiency (3)
- high progesterone
- high deoxycorticosterone
- serum 17-alpha-hydroprogesterone < 0.2 ng/ml
Describe tx: 17 alpha hydroxylase defiency (3)
- Exogenous glucocorticoid replacement therapy (hydrocortisone or dexamethasone)
- Mineralocorticoid receptor blockade (ex: spironolactone)
- Low-dose estrogen + progestin (2 yrs later)
DDX of uterus on pelvic ultrasound + low FSH (2)
hypothalamic or pituitary disorder
- congenital GnRH deficiency (ex: Kallman syndrome)
- constitutional delay of puberty
Name DDX of anatomic abnormality in pelvic ultrasound (for amenorrhea) (2)
- Outflow tract obstruction -> surgery
- Transverse septum (inside vagina)
- Imperforate hymen
- Absent uterus
Name DDX: Absent uterus (3)
- Mullerian agenesis (46XX - genetically female)
- Complete androgen insensitivity syndrome (46 XY)
- 5-alpha reductase deficiency (46 XY)
How to differenciate DDX: Absent uterus (2)
Karyotype + serum testosterone
- Mullerian agenesis (46XX - genetically female)
- Complete androgen insensitivity syndrome (46 XY)
- 5-alpha reductase deficiency (46 XY)
Describe sx: Mullerian agenesis (5)
- 46XX - genetically female
- Short vagina
- absent/rudimentary and obstructed uterus
- ovaries N, breast N
- Development/FSH/Testosterone
Describe tx: Mullerian agenesis (3)
- Psychological counceling
- Surgical creation of vagina + vaginal dilators
- Possible to have children via assisted reproduction techniques (egg harvesting, in vitro fertilization, surrogate pregnancy) OR uterus transplantation
Describe: Complete androgen insensitivity syndrome (5)
- Defective receptor, Testosterone N
- No tissues response:
- Female external genatalia
- Sparce body hair
- Almost no pubertal acne
- Well-developed breats
Describe management: Complete androgen insensitivity syndrome (3)
- Testes in abdomen/pelvis/inguinal canal -> high risk of cancer -> surgical removal after puberty
- Counceling
- Vaginal surgery/dilation
Describe: 5-alpha reductase deficiency (3)
- Do not undergo DHT-dependent masculinization during fetal development
- at birth: female or ambiguous external genitalia
- at puberty: testosterone levels rise ++ -> male-pattern hair growth, acne, muscle mass, deeper voice
Describe management: 5-alpha reductase deficiency (2)
- Counceling
- DHT therapy (if male) or estrogen therapy (if female)
