Q

Treatment for Kallman syndrome

A

Pulsatile GnRH agonist. This is because in Kallman syndrome there is olfactory tract hypoplasia and the arcuate nucleus does not secrete GnRH.

Q

True precocious puberty treatment

A

Due to increased pulsatile GnRH secretion at a young age, treat with continuous GnRH agonist if onset occurs well before avg puberty onset. If close to avg age observation is appropriate.

Q

Why use OCPs to help women with PCOS?

A

They establish regular menses, lower ovarian androgen production and cause an increase in SHBG which allows more testosterone to be bound and unavailable at the hair follicle…reducing hirsutism

Q

28
Q

How can you reach a diagnosis of PCOS in a woman with irregular menstrual bleeding and a hairy face?

A

Testosterone levels at the upper limits of normal (free testosterone is elevated because SHBG is decreased due to elevated androgens). LH is increased and FSH is decreased. Pts often have insulin resistance and chronic anovulation.

29
Q

Contraindications to OCPs

A

Age > 35, smokes, hx of cardiovascular disease

30
Q

When is laparoscopic myomectomy contraindicated?

A

If the fibroid is submucosal, you must take it out hysteroscopically.

31
Q

How do OCPs improve dysmenorrhea?

A

Progesterone causes endometrial atrophy, which is where the pro-inflammatory prostaglandins are produced that cause menstrual pains

32
Q

USPSTF recommendation for gonorrhea and chlamydia screening

A

All sexually active females age 25 and younger

33
Q

USPSTF recommendation for HPV screening

A

Paps at 21, antibody at 30, unless Paps show ASCUS.

34
Q

How does adenomyosis cause dysmenorrhea?

A

The gland tissue grows during the menstrual cycle and, at menses, tries to slough, but cannot escape the uterine muscle. This trapping of blood and tissue causes uterine pain in the form of monthly menstrual cramps.

35
Q

Tx for adenomyosis in women who wish to preserve fertility

A

Hysteroscopic endometrial ablation and levonorgestrel IUD

36
Q

When should all women get an endometrial biopsy when they present with irregular bleeding

A

> 40 years old

37
Q

What distinguishes a leiomyoma from a leiomyosarcoma?

A

More than 20 mitotic figures per high power field

38
Q

Premature ovarian failure age cutoff

A

35

39
Q

Optimal daily calcium intake for postmenopausal women

A

1200 mg of elemental calcium per day. Ca absorption decreases with age because there is a decrease in biologically active vitamin D

40
Q

Interval between DEXA scans for women with osteoporosis taking bisphosphonates

A

Every 2 years

41
Q

Risks of HRT

A

Breast cancer, myocardial infarction, cerebrovascular accident, and thromoboembolic events

42
Q

Most effective treatment for severe menopausal symptoms that include hot flashes, night sweats and vaginal dryness.

A

HRT with annual reviews regarding the decision to continue taking hormones

43
Q

Most common reason why women stop taking HRT

A

Bleeding and spotting usually happens in the first 6 months and causes women to stop therapy.

44
Q

Alternatives to estrogen that may be as effective in treating hot flashes

A

SSRIs, some anti-seizure medications and soy products

45
Q

HRT is not currently recommended for treatment of cardiovascular disease; however, how can HRT help someone with CVD

A

Estrogen increases triglycerides and increases LDL catabolism and lipoprotein receptor numbers/activity. This decreases LDL levels. Hormones inhibit hepatic lipase activity, which prevents conversion of HDL2 to HDL3, thus increasing HDL levels.

46
Q

WHO vs. ACOG definition of osteopenia

A

WHO: -1 to -2.5. ACOG: for scores of -1.5 to -2, T scores should be interpreted in combination with the patient’s risk factors (prior fracture, family history, race, dementia, history of falls, poor nutrition, smoking, low BMI, estrogen deficiency, alcoholism, and insufficient physical activity).

47
Q

Natural way to lessen menopause symptoms

A

Aromatize more androgens (androstenedione and testosterone) to estrogen by increasing fat stores.

48
Q

When would you think about ordering a semen analysis, ovarian function labs and HSG in a woman who is completely normal as far as fertility symptoms go?

A

After trying to conceive for > 12 months

49
Q

How common is infertility in patients who have one episode of salpingitis?

A

15.00%

50
Q

Lab that will help confirm the diagnosis of PCOS. Labs that help guide treatment of PCOS.

A

Confirm dx with elevated testosterone levels. Guide treatment by assessing progesterone, FSH and LH levels.

51
Q

How will patients with irregular menses due to hypothyroidism respond to OCPs?

A

They won’t respond. This helps differentiate PCOS from hypothyroidism.

52
Q

Management of infertility in patients with PCOS

A

1) Lose weight #2) Metformin + Ovulation induction agents (letrozole or clomiphene citrate)

53
Q

Drugs that can cause infertility via hyperprolactinemia

A

1) Dopamine antagonists (antipsychotics) 2) SSRIs 3) TCAs 4) Methyldopa 5) Metachlopromide

54
Q

Cause of exercise-induced hypothalamic amenorrhea? How do you treat?

A

Normal FSH and low estrogen levels due to insufficient caloric intake. Treat with supplemental FSH and LH if estrogen levels do not rise after increasing caloric intake. Clomiphene doesn’t work because of low estrogen levels.

55
Q

What test can you do to determine ovarian reserve in a woman struggling with infertility

A

Clomiphene challenge: give clomiphene on days 5-9 of menstrual cycle and checking FSH levels on days 3 and 10. (Clomiphene is a SERM than inhibits the negative feedback of estrogen on the hypothalamus, thus FSH should be elevated on day 10 if the ovaries have diminished reserve and FSH should be at baseline if ovarian reserve is normal and ovaries produced sufficient amount of estrogen to inhibit increased FSH levels)

56
Q

What does basal body temperature monitoring tell you about a patient’s menstrual cycle

A

Retrospective data on when they ovulated. If you want predictive data you need to use ovulatory urine kits that measure LH levels in the urine.

57
Q

How long is an ovulated egg viable for? How long are sperm viable for in the fallopian tubes?

A

Egg - 24 hours. Sperm - 3 days.

58
Q

Percentage of infertility cases due to male factor

A

35.00%

59
Q

Criteria necessary to diagnose someone with premenstrual dysphoric disorder (PMDD)?

A

5 out of 11 clearly defined symptoms, functional impairment and prospective charting of symptoms

60
Q

Deficiencies in which vitamins may exaccerbate or even cause PMS?

A

A, E, B6

61
Q

What is the difference between PMS and PMDD?

A

Adverse physical, psychological and behavioral symptoms occur during the luteal phase of the menstrual cycle in both. PMS is characterized by mild to moderate symptoms, while PMDD is associated with severe symptoms that seriously impair usual daily functioning and personal relationships.

62
Q

Pharmacologic treatment for clinically significant PMS

A

OCPs suppress the HPO axis and relieve symptoms

63
Q

1st step in managing a patient who has mood symptoms associated with menstrual periods

A

Menstrual calendar/diary for around 2 months to document symptoms to see if they really are from PMS or PMDD

64
Q

Medical management of patients with PMDD

A

SSRIs daily or just during the 1st 10 days of the luteal phase

65
Q

What are risk factors for development of PMS?

A

Family history of PMS, Vitamin B6, calcium, or magnesium deficiency. Increasingly common as women age through their 30s.
