Q

Menopause Hot Flashes

A
  • occur in 75% of menopausal women
  • Presentation: starts in face/chest then generalizes, lasts 2-4 min, associated with diaphoresis, and palpitations, followed by chills and shivering, may cause sleep disturbances

Treatment: estrogen replacement > SSRI or SNRI (venlafaxine) > Clonidine or gabapentin
Herbal Treatment: soy isoflavones, red clover, black cohosh, vitamin E ( = potential estrogenic effect on the breast, much like estrogen replacement)

Q

Vaginal Pain

A
  • Trauma
  • infections
  • muscular spasm
  • mucosal allodynia (pain from a stimulus that doesn’t usually cause pain)
  • hyperalgesia (ramped up pain pathway responses due to nerve damage or some kind of psychological issue)
  • vaginismus = spasm of pelvic floor muscles that causes pain when touched
  • vestibulitis - burning sensation at opening of vagina = pain when touching the glands (Bartholin or skene glands)

Treatment = desensitization
- remove painful stimuli

Q

Benign Vulvar Cysts

A

Bartholin gland and Skenes gland = normally important for vaginal lubrication

Bartholyn gland cyst

  • problem with the duct of the bartholyn gland or Skenes gland causing obstruction
  • making the gland to swell

Treatment = excision and drainage and make a new exit point for the duct to drain into the vagina
Any bacteria can be a cause of this (more associated with Chlamydia and gonorrhea) must drain before giving antibiotic

Q

Most common gynecological malignancy in the US

A

Endometrial Carcinoma

  • world wide = Cervical Cancer
17
Q

Medications for Pregnancy Termination

A

Misoprostol = Prostaglandin E1 agonist = causing uterine contractions

Mifepristone = progesterone and glucocorticoid antagonist

Methotrexate = folic acid antagonist

18
Q

Mentropin

A
  • human menopausal gonadotropin
  • mimics FSH and triggers formation of a dominant ovarian follicle
  • anovulation is a common cause of infertility
  • ovulation is then induced by administration of HCG which mimics the LH surge
19
Q

Amniocentesis Indications

A
  • abnormal maternal serum triple or quadruple screen
  • high risk for trisomy or other genetic defects (>35 yo; carrier of AR disease)
  • Evaluation of fetal lung maturity (lecithin:sphingomyelin ratio >2.0)
  • In Rh-sensitized pregnancy to detect fetal blood type or fetal hemolysis
  • Testing for infection

Timing

  • can’t be earlier than 15-17 weeks for genetic evaluation
  • performed in 3rd trimester for fetal lung maturity evaluation

Risks
- 1-2% of fetal/maternal hemorrhage, 0.5% fetal loss

20
Q

Chorionic Villus Sampling (CVS)

A
  • Performed at 10-12 weeks
  • needle biopsy of placenta

Risks
- 1% fetal loss, inability to diagnose NTD, limb defects if done

21
Q

Sleep Patterns in the Elderly

A
  • decreased REM sleep
  • decreased slow wave sleep
  • increased Sleep latency
  • increased nighttime awakenings
22
Q

Causes of Intellectual Disability

A

Most common cause overall = Fetal Alcohol Syndrome

1st most common when it comes to genetics = Down Syndrome

2nd most common when it comes to genetics = Fragile X syndrome

23
Q

Horseshoe Kidney, congenital heart defects, streak ovaries, and cystic hygroma

A

Turner Syndrome

24
Q

Most common cause of congenital retardation in men

A

Fragile X syndrome

25
Q

Ovulation

A
  • Peak levels of estrogen in the late follicular phase has a positive feedback effect on LH production which causes the LH surge
  • This LH surge causes the rupture of the follicle leading to extrusion of the secondary locate (ovulation)
  • FSH levels are highest just before ovultation
26
Q

Teratogens

A

Warfarin = causes nasal hypoplasia, stipples epiphysis

Vitamin A = Microcephaly, they mic hypoplasia, small ears, hydrocephalus

Lithium = hypothyroidism and Epstein anomaly

Phenytoin = causes fetal hydantoin syndrome ==>orofacial clefts, Microcephaly, digit or nail hypoplasia, cardiac defects, and dysmorphic facial features

27
Q

Kleinfelter Syndrome

A
  • primary hypogondadism
  • increased long bone length
  • gynecomastia
  • learning and socialization difficulties

Decreased testosterone
LH and FSH are increased due to loss of feedback inhibition
Increased Estradiol

28
Q

Vaginal Candidiasis

A

Normally gram + lactobacilli comprise a major part of the normal vaginal flora and exist in balance with other colonizers at a normal vaginal pH of 3.8-4.5

  • changes in vaginal flora and epithelial injury can lead to overgrowth of yeast, most commonly candida
  • Common triggers for candida vaginitis include: antibiotic use, high estrogen levels, systemic corticosteroid therapy, uncontrolled diabetes mellitus, and any other cause of immunosuppression including HIV
29
Q

Menopause vagina

A
  • decreased thickness of the vaginal epithelium and decreased amounts of glycogen in epithelial cells are characteristic in postmenopausal and lactating women
  • these changes are caused by low estrogen levels and lead to atrophic vaginitis
30
Q

Alpha Fetal Protein

A
  • synthesized by the fetal liver, GI tract, and yolk sac (early gestation only)
  • levels increase with gestation age
  • this is why accurate dating is crucial in performing the calculations involved in ddetermining risk status
  • Patients with a history of irregular menses are at risk for inaccurate pregnancy dating
31
Q

Increased AFP

A
  • Open neural tube defects
  • Ventral wall defects = omphalocele, gastroschisis
  • multiple gestational
32
Q

Gap junction stimulation

A

Immediately before delivery, estrogen stimulates up regulation of gap unctions between individual myometrial smooth muscle cells

  • An increase in gap junction density at delivery heightens myometrial excitability
  • Gap junctions consist of aggregated Connexxion proteins that allow passage of ions between myometrial cells
  • Estrogen also increases expression of oxytocin receptors that help mediate calcium transport through ligand-activated calcium channels
  • the combo of an increase in gap junction density and uterotonic receptors results in coordinated synchronous labor contractions
33
Q

ED

A
  • if the patient has morning erections then the erectile dysfunction is due to psychogenic impotence
34
Q

Endometriosis vs. Adenomyosis

A

Adenomyosis = uterus is uniformly enlarged

Endometriosis = no enlarged uterus

Fibroids = irregularly enlarged uterus

35
Q

Transverse Vaginal Septum

A
  • failed vertical fusion of the paramesonephric ducts with the urogenital sinus
  • the obstructive septum causes primary amenorrhea with cyclic pelvic pain from hematometra (menses retained in the uterus) and an HSG cannot be performed on these patients
36
Q

Virilazation in Pregnant mother and born child

A
  • This is due to aromatase deficiency in the placenta
  • there will be no conversion to testosterone which will increase the androgen levels in the mom and baby
  • Can’t be any of the congenital hyperplasia deficiencies because it won’t affect the mom due to aromatase being intact in the placenta

Aromatase converts androgens in the ovaries, testes, placenta, and other peripheral tissues
