Menstruation and Uterine Disorders Flashcards
What is primary amenhorrhea?
no hx of any menses:
- by age 15 in presence of normal growth and secondary sexual characteristics
- at age 13 in absence of secondary sexual characteristics
- at age 12-13 evaluate cyclic menstural pain (imperforate hymen?)
Etiology of primary amenorrhea?
- x’somal abnormality (gonadal dysgenesis, Turner’s syndrome) 50%
- hypothalamic hypogonadism 20%
- mullerian agenesis (absence of uterus, cervix and vagina 15%)
- transverse vaginal septum or imperforate hymen 15%
- other: CAH, PCOS, androgen insensitivity
Dx eval of primary amenorrhea - H and P?
- hx:
cyclic pelvic pain, other stages of puberty, HAs, virilization, galactorrhea, meds, stressors, wt change or illness
FH of delayed puberty - exam:
tanner staging (breast development is marker for estrogen = ovary), pelvic exam to confirm patent hymen and presence of vagina, signs of turners (low hairline, web neck, widely spaced nipples with shield chest)
Labs for primary amenorrhea?
- initial: FSH (if elevated - ovarian failure)
- further lab based upon FSH and presence or absence of breast development and uterus: could include karyotype, testosterone, TSH, prolactin, and pregnancy test
- initial imaging: US to confirm uterus
Causes of secondary amenorrhea?
- rule out pregnancy!
- ovarian (40%): PCOS 20%, PCO (less than 40 yo)
- hypothalamic:
fxnl (decreasd GnRH): wt loss, exercise
nutritional deficiences: low body fat, celiac
emotional stress or illness
infiltrative tumors: rare - pituitary:
hyperprolactioma
other causes of elev prolactin
injury to pituitary (sheehan’s syndrome, radiation, hemochromatosis)
hypothyroidism - uterine: asherman’s syndrome: acquired scarring of cavity, TB
Hx ?s to ask pt with secondary amenorrhea?
- menstrual hx
- exercise and eating patterns
- meds that may increase prolactin
- stress
- post partum hemorrhage
- radiation to head
- HAs
- hot flashes
- uterine surgeries
Exam for secondary amenorrhea?
- BMI
- hirsutism (PCOS)
- galactorrhea
- uterine size
- initial labs: pregnancy test, FSH, TSH, prolactin, possible testosterone and DHEA-S
Causes of primary dysmenorrhea (painful periods)?
Secondary?
- primary: no obvious cause, typically begins in adolescence as crampy, midline lower abdominal pain assoc with onset of menses
- secondary: sxs attributed to specific problem like endometriosis, adenomyosis or fibroids or PID
RFs for primary dysmenorrhea?
- younger than 30
- BMI less than 20
- smoking
- menarche b/f 12
- irregular/prolonged/heavy menses
- hx of sexual assault
- family hx
- younger age of first child and higher parity lower risk
Pathogenesis of primary dysmenorrhea?
- prostaglandins released with endometrial sloughing induce contractions
- uterine ischemia result in anaerobic metabolites which stimulates type C pain neurons
Presentation of primary dysmenorrhea?
- pain begins after ovulatory cycle established
- may start 1-2 days b/f menses, gradually diminishes over 12-72 hrs
- unilateral pain or non-cyclic pain suggests other dx
- nausea, diarrhea, HA may be present
Dx of primary dysmenorrhea?
- no PE findings
- no lab abnormalities
- no imaging study findings
- dx by hx and normal exam
What sxs wouldn’t line up with primary dysmenorrhea?
- need to focus on exclusion of secondary dysmenorrhea:
onset of sxs after 25
nonmidline pain
dyspareunia
progression of sxs
abnorm. uterine bleeding suggest secondary causes
1st tx of primary dysmenorrhea?
- self-care, heating pad, exercise, relaxation techniques
- NSAIDs (not if allergic to ASA)
- suppression of menses with contraceptive hormones
- limited data and small studies report reduced cramps with diet and supplements: low fat vegetarian diet; 3-4 dairy servings/day, vit E 2 days b/f through 1st 3 days of menses, 1-2 g fish oil/day, vit B1 100 mg/day, vit B6 mg/day
Causes of secondary dysmenorrhea?
- endometriosis
- fibroids
- intrauterine/pelvic adhesions
- obstructive endometrial polyps
- obstructive mullerian anomalies
- cervical stenosis
- pelvic congestion syndrome
- Adenomyosis
- ovarian cysts
- IUD
PALM-COEIN is used for?
- abnormal uterine bleeding (AUB) this replaced dysfunctional uterine bleeding
Basic labs for AUB?
- CBC (anemia, platelets)
- prolactin
- TSH
- pregnancy test
- chlamydia testing when indicated (inflamed cervix, post-coital bleeding)
- other lab and imaging studies as indicated by exam or hx
PALM-COEIN?
P= polyp A= adenomyosis L= leiomyoma M= malignancy
C= coagulation O= ovulatory dysfxn E= endometrial I= iatrogenic N= not yet classified
What is polymenorrhea?
Oligomenorrhea?
- have cycles less than 24 days
- have cycles that are longer than 35 days
What is menorrhagia? Metrorrhagia?
- menorrhagia: heavy menstrual bleeding
- metrorrhagia: bleeding b/t periods
What % of women presenting with heavy menstrual bleeding have underlying bleeding disorder? What is MC disorder?
- 20%
- VonWillebrands is MC (will have early hx of menorrhagia)
When should you refer a pt with ABU on for heme eval?
in addition to heavy menstrual periods plus - have hx of one of the following: -hx of postpartum hemorrhage -hx of unexplained bleeding with surgery -hx of bleeding with dental work
refer with 2 of following:
- frequent gum bleeding
- epistaxis or unexplained bruising 2x a month
- family hx of bleeding
Ovulatory causes of AUB?
caused by chronic unopposed estrogen influence as a result of anovulation or oligo-ovulation:
- hyperandrogenic (PCOS)
- hypothalamic dysfxn (anorexia)
- thyroid disease
- elevated prolactin
- meds
- iatrogenic
- premature ovarian insufficiency
What is PMS and PMDD?
- PMS= premenstrual syndrome
- PMDD= premenstrual dysphoric disorder
- cyclic physical and/or behavioral sxs that recur in luteal phase and first few days of menses (present for at least 3 months)
- severity of sxs are disruptive at home/social situations/at work
RFs for PMS and PMDD?
- genetics: variation of estrogen receptor alpha gene
- hx of traumatic events/anxiety disorder/ highly daily hassle scores
- lower education
- smoking
- PMS 3-8% with regular cycles
- PMDD 2% with regular cycles
PP of PMS and PMDD?
- unknown
- abnormal response to normal concentrations of estrogen and progesterone
- cyclic changes in circulating estrogen and progesterone trigger an abnormal serotonin (NT) response?
When do Sxs of PMS and PMDD usually start? What must these interfere with?
- usually starts in 20s
- must cause significant distress and interference with normal activities
Physical sxs of PMS and PMDD?
- abdominal bloating
- extreme fatigue
- breast pain
- HA
- hot flashes
- dizziness
Behavioral sxs of PMS and PMDD?
- mood swings
- irritability/anger
- depression
/hopelessness/self-critical - anxiety/tension/ feeling on edge
- for dx of PMDD must have at least one of the above and total of 5 sxs, 4 of which can be from expanded DSM-5 criteria. These sxs should have been present for most of the preceding year in a cyclic pattern with menses
Eval of PMS and PMDD?
- confirm regular menses and cyclic pattern of sxs
- lab: no specific test, consider TSH and CBC
- have pt complete a prospective sx inventory
Tx for mild PMS and PMDD?
- exercise and relaxation techniques
- no strong data that vitamins or supplements exceed the placebo response
Tx for moderate-severe PMS and PMDD?
- SSRIs: fluoxetine, sertraline, extended release paroxetine all have FDA approval
- 60-70% response, try different SSRI
Tx for PMS and PMDD that is refractory to SSRI?
- induce anovulation with: continuous/short pill free interval OC - evidence strongest for drospirenone, GnRH agonist
- surgery with BSO (and hysterectomy)
What is endometriosis?
- cells that behave like lining of the uterus grow in other areas of the body, causing pain, irregular bleeding and possbile infertility
- common, poorly understood, and extemely debilitating benign gyn condition
- psychological impact of the severe pain experienced by the patient is compounded by the possiblity of infertility (endometriosis has prevalence rate of 20-50% in infertile women and as high as 80% in women with chronic pelvic pain
Who does endometriosis affect?
- menstruating women
- postmenopausal endometriosis may be encountered in women who are on ERT: occasionally if ERT is admin after total abdominal hysterectomy endometriosis can be stimulated in an ovarian remnant
Etiology and PP of endometriosis?
- not well understood
- retrograde menstruation: endometrial cells loosened during menstruation may back up through the fallopian tubes into the pelvis, once there they implant and grow in the pelvic or abdominal cavities
- Halban theory: vascular and lymphatic dissemination
- meyer theory: metaplasia of multipotential cells
