Q

Cervical Screening guidelines for immunocompetent vs immunocompromised:

A

Immunocompromised- Screen at onset of sex (even if before age 21)

Immunocompetent- No screening before age 21 (they might be able to bounce back from HPV infx)

Q

Mainstay of therapy for PCOS?

A

OCPs and metformin (improves hirsutism, ovulation, and insulin resistance) are the mainstay of therapy for PCOS.

Spironolactone can be used to reverse some of the hirsutism.

Q

reason WHY a woman would not bleed AT ALL

A

Estrogen deficiency

Estrogen is required to build the endometrium. Without estrogen there is no building, so there is nothing to slough off even if progestin there to signal bleeding.

Q

Pelvic ultrasound shows normal ovaries with a moderate amount of free fluid in the peritoneum. Doppler shows good blood flow to the ovary. Diagnosis?

A

This is pain associated with follicular rupture/ bleeding from the ovarian capsule with rupture- which then irritates the peritoneum. A rupture of an ovarian cyst leads to free fluid and good blood flow to the ovary- in the absence of other scary things (positive pregnancy test, fever, white count, etc.)

Q

What is the associated tumor marker for yolk sac tumor?

A

AFP is found in yolk sac tumors and hepatocellular carcinoma

AFP is the only tumor marker which CAN be used to diagnose cancer. A characteristic lesion on ultrasound or triple-phase CT plus an elevated AFP is hepatocellular carcinoma - even without a biopsy.

Q

Little girl with precocious puberty with onset of secondary sex characteristic development that has come too soon. Tx?

A

Postpone menarche until she is able to hit her growth spurt. To do that, we turn off the axis with continuous leuprolide, turning off the axis at the source—the hypothalamus.

Q

What is savage/ resistant ovary syndrome?

A

Young female with menopause-like symptoms . Everything on axis is working fine (FSH, LH< estrogen, progestrone, prolactin) but no signal going to ovarian follicles for some reason

23
Q

What is premature ovarian failure?

A

Early menopause

very high FSH level with moderately elevated LH

24
Q

What is ovarian torsion?

A

Ovarian torsion presents with acute pain, often in conjunction with nausea and vomiting. It can spontaneously resolve- and the patient will appear completely normal- then quickly recur (torsion/detorsion). Presence of flow to the ovary on ultrasound does not rule out torsion.

25
Q

Woman with previous PID now with infertility

A

A history of pelvic inflammatory disease significantly increases the chances of anatomic failure.

The way to diagnose this anatomic defect is by looking with a hysterosalpingogram.

26
Q

Woman w/ combination of pain, bleeding, infertility, and abnormal uterine anatomy

A

asymmetric uterus combined with chronic pain and bleeding with her cycles is classic for fibroids

Fibroids are estrogen-responsive and get better with OCPs and after menopause.

27
Q

Why does a woman w/ PCOS have irregular periods?

A

anovalation- no oocyte released

so estrogen builds up the endometrium of uterus but there is no progesterone to signal bleeding. Eventually so much buildup that wall will bleed on its own–> random periods

28
Q

How does adrenal mass cause virilization?

A

Adrenals make DHEA– excess DHEA–> virilization (facial hair, acne, clitoromegaly, and a deepened voice)

29
Q

How does breastfeeding prevent amenorrhea?

A

breastfeeding–> Increased prolactin levels–> Inhibition of GnRH–> Decreased FSH/LH–> Decreased estrogen/progestrone

30
Q

How to diagnose PCOS?

A

PCOS is an endocrine diagnosis—Get LH:FSH ratio

Ultrasound is NOT part of the diagnostic workup for PCOS. - it will just show many cysts on ovaries

31
Q

What causes incomplete moles?

A

incomplete chromosomal structure- part fetus part not

Caused by a normal egg fertilized by two sperm (dispermy)

32
Q

Woman exposed to DES during pregnancy

A

Vaginal Adenocarcinoma of her daughter

Cancer will resemble a bag of grapes in vagina

33
Q

What causes complete mole?

A

Completely molar (no fetal parts)

caused by dysfunctional oocyte (egg has no nucleus)- only paternal DNA is expressed

34
Q

How will condyloma acuminatum present?

A

Growths/warts in genital area that are not itchy

Application of acetic acid changes the color of the lesions to white

35
Q

What causes condyloma acuminatum?

A

Anogenital warts caused by human papillomavirus (HPV)

Most common strains of HPV that cause anogenital warts are 6 and 11

36
Q

What is the treatment for condyloma acuminatum?

A

Treatment is with either imiquimod, podophyllin or trichloroacetic acid (if they are small)

Excision/fulguration (if they are large).

37
Q

ow do you treat lichen sclerosis?

A

Porcelain-white lesions and a narrowing of the introitus

Lichen sclerosis is an inflammatory condition, use anti-inflammatories (i.e. topical steroids)

It should first be biopsied to rule out cancer.

38
Q

How to diagnose Premature ovarian failure?

A

To diagnose menopause (or premature ovarian failure), look for an elevated FSH, decreased AMH, and antral follicle count.

AMH is a marker for follicles, it gradually decreases over a woman’s life; it is undetectable at menopause

39
Q

What is treatment for vaginal candida infection?

A

Treatment starts with topical fluconazole, progressing to po only if there is a failure of topical.

40
Q

What is treatment for RUPTURED ectopic pregnancy?

A

Exploratory laparotomy with a salpingectomy (the diseased pregnancy and the tube in which it is stuck come out)

41
Q

Girls exposed to Diethylstilbestrol (DES) in utero are at increased risk of?

A

Vaginal clear cell adenocarcinoma

Breast cancer

squamous cell cervical cancer

Exposed women should have an annual gynecologic exam

42
Q

Most common risk factor for ectopic pregnancy?

A

Pelvic inflammatory disease (PID)

43
Q

Sex cord stromal tumors

A

Leydig cell tumor
Leydig cell tumor
Granulosa cell tumor

44
Q

Leydig cell tumors

A

Hyperestrogenism- cause gynecomastia, decreased libido, testicular mass

eosinophilic cytoplasmic Reinke crystals

45
Q

Klinefelter syndrome

A

chromosomal aneuploidy XXY

Small and firm testes

severely subnormal sperm count and most are infertile

Elevated serum FSH and LH

46
Q

Dysgerminomas

A

Rapid growth on the ovary with elevated Lactate dehydrogenase and alkaline phosphatase

Abdominal enlargement and pain due to rupture with hemoperitoneum or torsion

47
Q

Fitz-Hugh–Curtis (FHC) syndrome

A

Extrapelvic manifestation of pelvic inflammatory disease (PID) caused by an ascending infection from the pelvis to the liver via the lymphatics of the pericolic gutter. This leads to patchy inflammation of the liver capsule

String-like adhesions

48
Q

Bicornuate uterus

A

Incomplete fusion of the paramesonephric (müllerian) ducts, resulting in 2 uterine cavities

Recurrent abortions, dysmenorrhea, dyspareunia, cyclic pelvic pain, and infertility

49
Q

Septate uterus

A

septate uterus has a normal external surface but 2 endometrial cavities

Tx: Surgical repair with resection of the septum hysteroscopically

50
Q

Unicornuate uterus

A

asymmetric lateral fusion defect

One cavity is usually normal, with a fallopian tube and cervix, while the failed müllerian duct has various configurations

51
Q

Duplication of the haploid genome of a single sperm following fertilization of an ovum without maternal genetic material

A

Complete molar pregnancy

46 XX or 46 XY

Snowstorm or Swiss cheese pattern

Very elevated typically >100,000 mIU/mL

52
Q

Fertilization of an ovum by two sperm where maternal genetic material is present

A

Partial molar pregnancy

69 XXX, 69 XXY, 69 XYY

Beta-hCG slightly elevated or within normal limits

53
Q

Evaluating a patient with an imperforate hymen.

A

Pelvic ultrasound is not only important when confirming the diagnosis of imperforate hymen, but additionally important to evaluate for other uterovaginal abnormalities

If this is the case, further imaging studies are indicated, typically with MRI.

54
Q

pelvic inflammatory disease (PID) treatment

A

Cultured Chlamydia trachomatis: Treat with azithromycin only
Cultured Neisseria gonorrhoeae: Treat with ceftriaxone AND azithromycin
Unknown etiology of sexually transmitted infection: Treat with ceftriaxone AND azithromycin
PID: Treat with doxycycline AND cefoxitin
Fitz-Hugh–Curtis syndrome: Treat with doxycycline AND cefoxitin

55
Q

placental abruption

A

Suspect placental abruption in all patients complaining of painful vaginal bleeding with uterine contractions.

56
Q

maximum recommended adult daily dose of acetaminophen

A

maximum recommended adult daily dose of 4000 mg (4 g).
