Q

A 30-year-old woman complains of bilateral breast enlargement and tenderness, which fluctuates with her menstrual cycle. On physical examination, the breast feels lumpy, and there is a painful, discrete 1.5-cm nodule. A fine-needle aspiration is performed, and clear liquid is withdrawn. The cyst collapses with aspiration. Which of the following is the next step in management?

a. Clinical breast exam in 6 weeks
b. Core needle biopsy
c. Mammography
d. Repeat FNA in 6 weeks
e. Ultrasound in 6 weeks

Fischer, Conrad (2012-09-22). Master the Boards: USMLE Step 3 (Kaplan Medical Usmle Master the Boards Step 3) (Kindle Locations 13725-13746). Kaplan Publishing. Kindle Edition.

A

A. Clinical breast exam in 6 weeks is appropriate follow-up for a cystic mass that disappears after FNA. If the mass recurs on the 6-week follow-up, FNA may be repeated, and a core biopsy can be performed

Q

Cystic Breast Mass

Indications for mammography (> 50 years) and Biopsy

OR

Biopsy alone if < 40 years

A
  • Cyst recurs > twice within 4 to 6 weeks
  • There is bloody fluid on aspiration
  • Mass does not disappear completely upon FNA
  • There is bloody nipple discharge (excisional biopsy)
  • There are skin edema and erythema suggestive of inflammatory breast carcinoma (excisional biopsy)

Mammogram should be done before biopsy. Biopsy distorts radiography

Q

True or False:

Fine-needle aspiration or core biopsy is needed for a palpable mass

A

True. May be done after ultrasound or instead of ultrasound.

Core biopsy is superior to FNA

Cytology: – Any aspirate that is grossly bloody must be sent for cytology. Observation with repeat exam in 6– 8 weeks: – Cyst disappears on aspiration, and the fluid is clear.

A

C. Sudden onset of severe lower abdominal pain in the presence of an adnexal mass is presumed to be ovarian torsion. Laparoscopy and detorsioning of the ovaries is needed. If blood supply is not affected, cystectomy can be done. If there is necrosis, oophorectomy is needed. She should then receive a 4-week follow-up and yearly evaluation to ensure there is complete resolution

  3. Frequency of screening:
    • If < 30 years old, annually for conventional Pap or every 2 years for liquid-based
    • If > 30 years old, screen every 2 to 3 years if > 3 consecutive negative Pap smears

Cervical cancer screening guidelines per the USPSTF:

  • Pap screening not recommended for women > 65 with recent normal Pap smear
  • Pap smear not recommended for women with total hysterectomy for benign disease
  • HPV testing alone is not sufficient for screening

A
  1. First ASCUS Pap
  2. First ASCUS Pap
  3. An abnormal Pap smear; Two ASCUS Pap smears
  4. All NONpregnant patients with an abnormal Pap smear

NOTES

Note on 1

  • Repeat Pap at 4- to 6-month intervals until there are 2 consecutive, negative Paps

  • If conventional methods were used, a second Pap needs to be performed
  • Colposcopy is then performed only if HPV 16 and 18 identified

Notes on 3

  • Colposcopy and ectocervical biopsy – Colposcopy is a magnification of the cervix (10– 12 times)
  • Abnormal lesions (e.g., mosaicism, inflammatory punctation, white lesions, abnormal vessels) are biopsied and sent for histology

Notes on 4

  • All nonpregnant patients undergoing colposcopy for an abnormal Pap smear must undergo an ECC to rule out endocervical lesions

96
Q
  1. Explain the pathphysiology of increased testosterone in PCOS
  2. Explain the pathogenesis of ovarian enlargement in PCOS
A
  1. ↑ LH levels → ↑ theca cell production of androgens → hepatic production of SHBG is suppressed → ↑ total testosterone and ↑ free testosterone
  2. ↑ androgens → multiple follicles in various stages of development, stromal hyperplasia, and a thickened ovarian capsule → bilaterally enlarged ovaries

Ultrasound shows a necklacelike pattern of multiple peripheral cysts (20– 100 cystic follicles in each ovary)

SHBG=Sex Hormone Binding Globulin

103
Q

List and explain the menopausal symptoms due to estrogen

A

Amenorrhea: Menses become anovulatory and decrease in the 3– to 5-year period known as perimenopause

Hot flashes: This is unpredictable, profuse sweating and heat that occurs in 75 percent of women. Obese women are less likely to undergo hot flashes (due to peripheral conversion of androgens to estrone)

Reproductive tract: Decreased vaginal lubrication*, *increased vaginal pH, and increased vaginal infections can occur

Urinary tract: Increased urgency*, *frequency*, *nocturia, and urge incontinence can occur

Psychic: Depressed mood,* *emotional lability,* and *sleep disorders can occur

Cardiovascular disease: This is the most common cause of mortality (50 percent) in postmenopausal women

107
Q

How is the diagnosis of osteoporosis made?

A

Bone density is assessed with a DEXA scan (dual-energy x-ray absorptiometry). The results are reported as a T-score: T-score ≥ –2.5 indicates the presence of osteoporosis

  • T-score –1.5 to –2.5 = osteopenia
  • T-score ≥ –2.5 = osteoporosis

Calcium loss is assessed with a 24-hour urine hydroxyproline or NTX (N-telopeptide, a bone breakdown product)

108
Q

Outline the management of osteoporosis

A
  1. First-line therapy is bisphosphonates and SERMs
    • Bisphosphates (e.g., alendronate, risedronate) inhibit osteoclastic activity
    • Selective estrogen receptor modulators (SERMs) increase bone density
    • SERMs are protective against the heart and bones but are not effective for vasomotor symptoms of menopause
    • Tamoxifen (Nolvadex) has endometrial and bone agonist effects but breast antagonist effects
    • Raloxifene (Evista) has bone agonist effects but endometrial antagonist effects
  2. Calcitonin, denosumab, and teriparatide are second-line therapy. Teriparatide is a PTH analog that is used when biphosphates fail
  3. Estrogen is never the primary treatment of osteoporosis because of associated risks of clots and endometrial cancer

Denosumab is a RANKL inhibitor that inhibits osteoclast function

Q

A 35-year-old woman comes to the gynecologist’s office complaining of infertility for 1 year. She and her husband have been trying to achieve pregnancy for > 1 year and have been unsuccessful. There is no previous history of pelvic inflammatory disease, and she had used oral contraception medication for 6 years. The pelvic examination is normal. Semen analysis is low volume and shows decreased sperm density and low motility. What is the next step in management?

a. Administer testosterone
b. Measure serum testosterone
c. Measure thyroid hormone
d. Repeat semen analysis
e. Refer for intrauterine insemination

D. Because semen samples are variable, an abnormal semen analysis is repeated in 4– 6 weeks to confirm findings

. Infertility is defined as inability to achieve pregnancy after 12 months of unprotected and frequent intercourse. Steps in workup for infertility: 1. The first step is semen analysis. 2. If semen analysis is normal, work up for anovulation. 3. If semen analysis is normal and ovulation is confirmed, work up for fallopian tube abnormalities. Step Diagnosis Management 1. Semen Analysis Normal values: • Volume > 2 mL; pH 7.2– 7.8; sperm density > 20 million/ mL; sperm motility > 50%; and sperm morphology > 50% normal. • If values are abnormal, repeat the semen analysis in 4– 6 weeks. • Abnormal semen analysis: Intrauterine insemination, intracytoplasmic sperm injection (ICSI), and in vitro fertilization (IVF) are fertility options. • No viable sperm: Artificial insemination by donor may be used. 2. Anovulation • Basal body temperature (BBT) chart: NO midcycle temperature elevation • Progesterone: Low • Endometrial biopsy: Proliferative histology • Hypothyroidism or hyperprolactinemia are causes of anovulation that can be treated. • Ovulation induction: – Clomiphene citrate is the agent of choice. – Human menopausal gonadotrophin (hMG) is used if clomiphene fails – Most common side effect = ovarian hyperstimulation. Ovarian size must
