metrorrhagia - bleeding between reuglar menstrual periods. this bleeding is usually less than or equal to normal menstrual volume. Primary causes:

A

cervical lesions (polyp, eversion, and carinoma and endometrial polyps and carcinoma)

32
Q

oligomenorrhea periods greater than 35 days apart

A

t

33
Q

most common causes of oligomenorrhea are PCOS, chronic anovulation, and pregnancy. thyroid disease should also be considered. when t has no period for 6 months, SECONDARY AMENORRHEA is diagnosed

A

t

34
Q

polymenorrhea - frequent periods, regular periods that occur less than 21 days apart. this is usually caused by anovulation

A

t

35
Q

evaluation of abnormal uterine bleeding. look for PCOS sequelae - hirsutism, acne, truncal obesity, acanthosis nigricans

A

t

37
Q

obese patients with prolonged oligomenorrhea should undergo endometrial biopsy even if they are younger than 45. these women are at increased risk of endometrial hyperplasia and cancer due to the peripheral conversion of androgens into estrogens in their adipose cells.

45
Q

anovulation

A

combined estrogen/progestin pills, patch or ring, or cyclic progestin

46
Q

dysfunctional uterine bleedinga; most patients with DUB are anovulatory. in these instances, ovary produces estrogen but no corpus luteum is formed, and thus no progesterone is produced. subsequently there is continuous estrogenic stimulation of the endometrium without the usual progesterone-induced bleeding. Instead, in DUB, the endometrium continues to proliferate until it outgrows its blood supply, breaks down, and sloughs off in an irregular fashion. DUB is most likely to occur with anovulatory cycles and thus is most common during times in a woman’s life when she is most likely to be anovulatory such as adolescence, perimenopause, lactation, and pregnancy

A

t

47
Q

pathologic anovulation occurs in hypothyroidism, hyperprolactinemia, hyperandrogenism, and POI/PMOF

A

t

48
Q

diagnosis of dub is made by r/o other causes of abnormal bleeding. in adolescence, risk of structural causes of abnormal bleeding disorder is small. however, any congenital anomalies and bleeding disorders should be eliminated. in the reproductive years, there is an increase risk of strutural and hormonal etiologies for abnormal bleeding. during perimenopause, risk of DUB increases, but so does the risk of other causes of abnormal bleeding including fibroids, polyps, adenomyosis, ,and endometrial hyperplasia and cancer

A

t

49
Q

any woman 45 years and older with abnormal uterine bleeding should undergo an endometrial biopsy to rule out endometrial hyperplasia and cancer

A

t

50
Q

midluteal, day 21-23 serum progesterone level may also indicate if a patient is ovulating. an endometrial biopsy showing decidualized or luteal phase endometrium, is evidence of ovulation and progesterone effect upon the endometrium

A

t

51
Q

treatment of acute hemorrhage in DUB

A

intravenous estrogen (25mg conjugated estrogen every 4hours up to 24hours provides a quick response, but also carries an increased risk of venous thromboembolic events (dvt, PE)

52
Q

treatment of hemodynamically stable pts in DUB

A

high-dose oral estrogens can control the bleeding within 24-48 hours. typical dosing might be
2.5mg every 4 hours for 14-21days followed by medroxyprogesterone acetate 10mg per day for 7-10days

ocp taper can also be used for endoemtrial stabilization. typical taper would use a monophasic pill containing 35mcg ethinyl estradiol given three times a day for 3 days, then two times a day for 2 days, then daily for the remainder of the pack.

53
Q

for chronic DUB

A

nonhormonal therapy with NSAIDS (800mg ibuprofen TID X 5 DAYS has been shown to decrease menstrual blood loss by 20-50%. this therapy may be used in conjunction with estrogen and progesterone therapy

54
Q

menstrual regulation using hormonal therapy is primary treatment for anovulatory DUB. this can include use of combination estrogen and progesterone in form of oral contraceptive pills, ortho evra patch, or nuvaring. may be dosed in a continuous(preferred) or cyclic fashion depending on patient’s desire

A

t

55
Q

in patients whom use of estrogen is contraindicated (hypertension, thrombophilias, history of DVT or PE and those 35 and older who smoke) or those who prefer an alternative to estrogen/progestin combination , similar cycle control can be achieved using progestin-only options. such as

A

10mg medroxyprogesterone acetate qd x 10days
depo provera
mirena
implanon
last 3 likely to result in light menses / amenorrhea over time.

Mirena IUD particularly is helpful in anovulatory and ovulatory pts with menorrhagia including those who are at increased risk for developing endometrial hyperplasia/cancer

56
Q

the most common cause of postmenopausal bleeding is

A

endometrial and/or vulvar atrophy, no tcancer.

57
Q

nonegynecologic causes of postmenopausal bleeding: rectal bleeding from hemorrhoids, anal fissures, rectal prolapse, and lower gastrointestinal tumors.

A

t

58
Q

vaginal atrophy is due to lack of endogenous estrogen is the most common source of lower genital tract postmenopausal bleeding.

A

t

59
Q

pathologic causes of PMB from upper genital tract include

A

endometrial atrophy, endometrial polyps, endometrial hyperplasia, and endometrial cancer.

60
Q

use of exogenous hormones is another common cause of PMB

A

t

61
Q

it is possible to find endometrial hyperplasia or cancer in the base of an otherwise benign-appearing endoemtrial polyp

A

t

62
Q

the addition of exogenous estrogens is contraindicated in any woman with unexplained vaginal bleeding. urogenital atrophy is not an indication for systemic HRT

A

t

63
Q

following polypectomy, pt would likely benefit from low-dose vaginal estrogen to treat her atrophy

A

t

64
Q

diagnosis of pms relies upon demonstrating symptoms worsen in the luteal phase (1-2 weeks prior to onset of menses), and resolve completely with the start/shortly following onset of menses

A

t

65
Q

ssri such as prozac, paxil, celexa, and zoloft, effective for treating both physical as well as mood symptoms associated with PMS. Prozac is FDA approved for this use.

Older studies do not show OCPS to be effective in treating PMS symptoms. however, newer formulations using progestin drospirenone ( a spironolactone with antimineralocorticoid and antiandrogenic activity ) and a 4 day rather than 7 day pill free interal has been shown to be effective in treatment of pMS

A

t

66
Q

if pt having symptoms throughout the cycle and no longer appears to have complete resolution of symptoms following onset of a period, consider underlying mood disorder such as depression

A

t

67
Q

medications in SSRI category are effective in treatment of mood disorders, to treat mood disorders, they must be given on a daily basis and not limited to the luteal phase as it is often done in treatment of PMS

A

t

68
Q

prozac used for PMS/PMDD take menstrual cycle day 7-10 . 10mg which is normal dose for anxiety/depression is too high for PMS/pMDD

A

t

69
Q

common cause of amenorrhea in young women is HYPOTHALAMIC HYPOGONADISM - frequently in athleteswho engage in vigorous dialy exercise as well as in women with eating disorders including anorexia and bulimia. inquiring about her daily exercise and diet is the most correct answer in this situation

A

t

70
Q

post pill amenorrhea can last up to ___ after discontinuation

A

6 months

71
Q

most common etiologies for anovulation include PCOS, pregnancy, hypo or hyperthyroidism, and hyperprolactinemia.

A

t

72
Q

17-OH progesterone, DHEAS, and testosterone are used to look for causes of hirsutism

A

t

73
Q

ultrasound an be used in supporting dx of PCOS by identifying multiple immature ovarian follicles “string of pearls”

A

t

74
Q

in women with PCOS, chronic anovulation often results in oligomenorrhea / amenorrhea with occasional, irregular episodes of bleeding that can be heavy and prolonged. prolonged stimulation of endometrium by estrogen without regular exposure to progesterone ( at ovulation) can lead to endometrial hyperplasia as well as endometrial cancer.

A

t

75
Q

metformin 500mg once daily, increase to 500mg BID after 1 week, then increase to 500mg TID after another week.
most effective dose for PCOS is 500mg TID. take with meals
