Study These Flashcards

< 45 yo with AUB +

RFs for unopposed estrogen exposure
Persistent bleeding
Failed med management of AUB

What is inpatient management for acute AUB?

Admit if heavy bleeding w/ signs/ sxs _or_ hemodynamic instability Treat w/ IV estrogen or possible D+C (dilation and curettage)

What is part of outpatient management of acute AUB?

Hormonal treatments, tranexamic acid IV or oral (alternative to hormonal tx)

What hormonal treatments are included in the management of acute AUB?

COCs (monophasic pill w/ 35mcg ethinyl estradiol- 3 pills qd x 7 days) Provera- oral High dose oral estrogen w/ antiemetic

What is included in the medical management for chronic AUB?

Hormone therapy (Mirena IUD), tranexamic acid, NSAIDS

What is included in the surgical management for chronic AUB?

Endometrial ablation, hysterectomy (extreme cases), endometrial artery embolization or myomectomy for leiomyomas

What is the major cause of AUB on both ends of the reproductive spectrum?

Anovulation (immature HPO axis for 13-18 yo and perimenopause for 40 yo- menopause)

Anovulatory AUB is usually unpredictable bleeding while ovulatory AUB is usually what?

Regular cycle length and + sxs a/w ovulation

What is defined as painful menstruation in the absence of disease, occurs during ovulatory cycles, and typically affects ages 17-22?

Primary dysmenorrhea

What is defined as painful menstruation due to organic pelvic disease and is more common as a woman ages?

Secondary dysmenorrhea (most common in 30-40 yo)

What is the pathogenesis of primary dysmenorrhea?

Prostaglandins released from endometrium during cell lysis (when ovum not fertilized) → uterine contractions and ischemia → pain

Pt c/o of cramp-like and intermittent pain beginning a few hours before or just after onset of menstruation that lasts 12-72 hours. Pain is most intense in lower abd (+/- radiation). What are you concerned for?

Is pelvic exam usually N or abn with primary dysmenorrhea?

Normal

How is primary dysmenorrhea diagnosed?

**Clinical diagnosis** (consider HCG, pap smear/ cultures)

Aside from self care (heat, massage, exercise, nutrition supplements, smoking cessation), what is used in the treatment of primary dysmenorrhea?

**NSAIDS (first line therapy)** Hormonal contraceptives (reduce menstrual flow and inhibit ovulation)

What should be considered in the treatment of primary dysmenorrhea if resistant?

Laparoscopy and/or possible GnRH analogue

In any of the following cases of primary dysmenorrhea, what is indicated? * Pain worsening w/ each menses * Pain lasts longer than first 2 days of menses * Meds no longer controlling pain * Menstrual bleeding becomes increasingly heavy * Pain + fever * Abn discharge or bleeding * Pain occurs at times unrelated to menses

Follow up and/or referral

Pt presents with pain less related to 1st day of menses, not limited to menses but worsens around this time. What are you concerned for?

Secondary dysmenorrhea

Secondary dysmenorrhea is usually a/w what?

Other sxs (dyspareunia, infertility, AUB)

The following are common causes of what? Endometriosis, adenomyosis, adhesions, PID, leiomyomas

Secondary dysmenorrhea

What is included in the management of secondary dysmenorrhea?

**Treat underlying cause** Hormone therapy (COCs), pelvic surgery if complicated (**refer**) (pelvic surgeries: dx laparoscopy, hysterectomy, oophrecomy, myomectomy)

How is pre-menstrual syndrome (PMS) defined?

Physical + behavioral changes that occur in a regular, cyclic relationship to **luteal phase** that interfere with some aspect of pts life

What is defined as PMS with more severe emotional sxs?

PMDD (premenstrual dysphoric disorder) (premenstural sxs → PMS → PMDD)

Although etiology of PMS is possibly due to N hormone fluctuations triggering an abn serotonin response, it is ultimately what?

Unlcear

What is decreased in the progesterone-dominant luteal phase? (possibly attributing to PMS)

Serotonin

Abd bloating, fatigue, swelling, breast tenderness, and HAs are a/w what?

Menstrual cycle associated disorders (PMS) (physical sxs)

Labile mood/ irritability, sad/ depressed mood, anxiety/ tension, sensitivity to rejection, diminished interest in activities, and increased appetite/ food cravings are a/w with what?

Menstrual cycle associated disorders (PMS) (affective/ behavioral sxs)

According to the diagnostic criteria for PMS, how many sxs must be physical, behavioral, or affective/ psychological in nature **OR** how many sxs must be physical/ behavioral?

* 1-4 sxs that are physical, behavioral, or affective/ psychological **OR** * ≥ 5 sxs that are physical _or_ behavioral

How many of set 1 criteria PLUS how many of set 2 criteria must be present for a DSM-5 dx of PMDD? Set 1 * Mood swings, sudden sadness, increased sensitivity to rejection * Sense of hopelessness, depressed mood, self-critical thoughts * Anger, irritability * Tension, anxiety, feeling on edge Set 2 * Difficulty concentrating * Change in appetite, food cravings * Diminished interest in usual activities * Easy fatigability, decreased energy * Feeling overwhelmed, out of control * Sleeping too much or not enough * Breast tenderness, bloating, weight gain, joint/ muscle aches

1+ AND 1+ (must have 5/11 sxs overall)

According to DSM-5 criteria for PMDD, sxs must be what?

* **Present in most menstrual cycles over previous year** * Present during wek prior to menses/ resolving w/ onset * A/w significant distress/ interference w/ usual activities

What is the most notable difference between PMS/ PMDD and MDD?

Monthly cyclicity

Management for PMS or PMDD is based on what?

Sxs

The following are used as non-pharmacologic txs for what? * Decrease salt, caffeine, alcohol * Aerobic exercise * Supplements * Stress reduction * Cognitive therapy

PMS/ PMDD with mild sxs

Pharmacologic treatment of PMS/ PMDD might include what?
