Endometrial ablation indications and what is it?
Abnormal uterine bleeding unrelated to malignancy Conservative surgical approach in which only the lining of the uterus is destroyed or removed. Endometrial ablation is not intended to replace hysterectomy, but offers women another choice for treatment of abnormal uterine bleeding.
Treatment design based on site of bleeding in perimenopausal bleeding. [she totally skipped this]
Atrophic vaginitis: Topical estrogen -Endometrial hyperplasia: continuous Progesterone x 3-6 months, then re-biopsy -Endometrial atrophy: due to hypoestrogenism resulting in thinning of surface that is prone to bleeding Try cyclic or continuous HRT
What is next step after determining they are hemodynamically stable and they don't need to go to ED?
Baseline CBC, quantitative BHCG [actual number, helpful if worried about someone miscarrying] Coagulation panel Suspect in teens with menorrhagia TSH, PROLACTIN Recurrent anovulatory bleeds Can also do Pap smear Biopsy of suspicious lesion Check for STD's

Develop from smooth muscle cells Cause for growth is unknown [estrogen sensitive, but bot caused by estrogen]
tx of DUB: surgical options.
Dilation and Curettage: Quickest way to stop bleeding in patients who are hypovolemic appropriate in older women (>35) to exclude malignancy but is inferior to hysteroscopy Ablation: [have to be done having kids] Microwave ablation Electromagnetic ablation Thermal balloon ablation Novasure Hysterectomy

how do pts present with DUB?
Patients present with "abnormal uterine bleeding"
point of DUB evaluation slide: [in notes section]
Point of this slide is there are many questions that need to be asked Does she have sxs of infection Bleeding from multiple sights Symptoms of hypothyroidism etc... Cervical cultures and gram stain should be obtained Inspection of the vagina identifies trauma, severe infections, atrophy, foreign bodies Inspection of the cervix may identify polyps, erosions, cancerous lesions A symmetrically enlarged uterus may suggest adenomyosis if not pregnant A uterus with asymmetric contours may suggest fibroids

central pelvic massess ddx
Pregnancy Leiomyomata - uterine fibroids Endometrial malignancy or uterine sarcoma Ovarian or other laterally located masses may present centrally Bladder
May see Hegar's and Chadwick's sign in pts who are ??
Pregnant. Bimanual exam: uterine enlargement Hegar's sign: (softening of the cervical isthmus, the portion of the cervix between the uterus and the vaginal portion of the cervix) -Check for Adnexal masses -Speculum exam: Chadwick's sign (bluish appearance to vaginal mucosa caused by increased blood flow.)
coagulopathy, what may the presentation be?
Presentation may be menorrhagia
Step 6 (Adults):
Proliferative endometrium or hyperplasia without atypia -assume DUB -manage according to desired fertility Hyperplasia with atypia or CA -treat accordingly [Adults with bleeding, who are not pregnant, and whose biopsy reveals proliferative endometrium or simple hyperplasia without atypia most likely have anovulatory DUB]

Stepwise approach to abnormal bleeding, step 1?
Rapid assessment of vital signs: Hemodynamically stable?

Rarely occur before menarche or after menopause Grow larger during pregnancy
Step 5 (Adults):
Secretory endometrium: >50% have polyp or submucosal fibroid Do Saline Ultrasound (SIS) or dx hysteroscopy -lesion present: biopsy/excision -lesion absent: R/O systemic disease
tx of DUB: acute bleeding for missed physiologic luteal phase
Substitute a pharmacologic luteal phase
If someone (ie. adolescent) has an immature HPO axis, what do you do?
These patients respond ideally to progestins. Regular cyclic withdrawal bleeding can be induced until maturity of the positive feedback mechanism occurs. Therapy: Progestin therapy 10 days every month or every other until full maturity of the axis provides effective therapy Low dose OCP's
With ovulation the size of the follicle about to rupture can be as large as 2.5cms. Total ovary may be how big mid-cyle? Any cyst larger than ? hanging off the ovary needs further investigation
Total ovary may be 6cms at mid-cycle! any cyst > 3cms needs further investigation

Tx of Luteal Phase Defect?
When unexplained infertiliy: If desires pregnancy: treat with clomiphene + progesterone
Can Pregnancy cause abmml bleeding?
Yes. [can have implantation bleeding] Spontaneous abortion (SAB): Retained products of conception Ectopic Pregnancy: Spotting 2o to fluctuating estrogen and progesterone levels leading to withdrawal bleeding Gestational Trophoblastic Neoplasms: (molar pregnancy) [abmnl levels of HCG, not a viable pregnancy] Placental polyp !Complications of pregnancy are the MCC of abnormal bleeding in reproductive age women; should be considered until proven otherwise bc several of these conditions can be life threatening.!

Breasts: galactorrhea, what would be first on differential?
[prolactinoma, prolactin >20 then consider prolactinoma]
Ovulatory DUB occurs most commonly after _____ and before _____?
after the adolescent years and before the perimenopausal years.
The main cause of DUB is :
anovulation resulting from altered neuroendocrine and/or ovarian hormonal events. In premenarchal girls, FSH > LH and hormonal patterns are anovulatory. The pathophysiology of DUB may also represent exaggerated FSH release in response to normal levels of GnRH (Gonadotropin-releasing hormone). After menarche, normal adult FSH and LH patterns eventually develop with mid-cycle surges and E2 peaks.
Two types of DUB:
anovulatory and ovulatory
What is the MCC of DUB in adolescents?
anovulatory cycles d/t (maturing hypothalamic-pituitary axis)
most are of what type?
anovulatory. Most women with DUB do not ovulate.

Intermenstrual bleeding definition
bleeding of variable amounts occurring between regular menstrual periods
DUB is most frequently associated with ?

Tx of DUB goals:
control bleeding prevent recurrence preserve fertility correct associated conditions induce ovulation in patients who want to conceive
Dx of Luteal Phase Defect?
endometrial biopsy (EMB) >2days out of phase of cycle
Tx of DUB, medical management is preferred initial tx before surgery, such as?
estrogens, progestins [OCP usu first choice] NSAID's [for pain] antifibrinolytic agents [not usu used as much] danazol GnRH agonists [depends on age, desire to return to fertility]
Polymenorrhea definition
frequent but regularly timed episodes of bleeding with a cycle length of <21days (opposite of oligomenorrhea)
What are common sx's of DUB?
heavy menses, prolonged menses, or frequent irregular bleeding.
NSAIDs usu used in conjunction with?
hormone therapy NSAID's: Cyclooxygenase inhibitors inhibits prostacyclin formation First 3 days of menses. Treatment results in a sustained reduction in blood loss so side effects tend to be mild Most effective in ovulatory DUB
[take home for coagulopathy?]
in teenagers c/o heavy periods, ask FH and do coagulopathy w/u Congenital factor deficiencies mainly in teenagers with menorrhagia since menarche Thrombocytopenias -Easy bruising, bleeding gums, slow to clot -Suppress menses with oral progestins (e.g. continuous OCs) until platelets increase
