Q

What are the causes of dysfunctional uterine bleeding?

A

Reproductive tract disease = pregnancy, gastational trophoblastic disease, uterine lesions, iatrogenic causes (IUDs, contraception, HRT, psychotropic agents)

  • uterine lesions: menorrhagia or metrorrhagia d/t increase in endometrial surface area/distortion of vasculature/having friable or inflamed surface = includes endometrial CA/sarcoma, endometrial hyperplasia, submucosal fibroid, enometrial polyps, endometritis, adenomyosis
  • systemic disease = blood dyscrasias (vWD, prothrombin deficiency, leukemia, severe sepsis), hypothyroidism, hyperthyroidism, cirrhosis
  • hypothyroidism assocaited with menorrhagia or metorrhagia; hyperthyroidism associated with oligomenorrhea and amenorrhea
  • cirrhosis can cause excess bleeding d/t low plts and less metabolization of estrogens
  • endocrine causes = anovulatory vs ovulatory DUB
  • anvolutatory:
  • continous production of estradiol-17 beta without corpus luteum formation and no progesterone release
  • unopposed estrogen = continous proliferation of endometrium which eventually outgrows its blood supply and sloughs of in an irregular unpredictable pattern
  • ovulatory:
  • mid-cycle spotting after LH surge

Q

How is dysfunctional uterine bleeding dx?

A

  • med reconciliation
  • PE = thyromegaly, hepatomegaly, GU infection, GI problems (hemorrhoids), pelvic structural abnormalities (polyps, fibroids)
  • labs = FSH, LH, prolactin, estradiol, testosterone, TSH, T3, T4, DHEAS, coags
  • eval of uterus = endometrial biopsy or hysteroscopy, pelvic US
  • uterine dilation and curettage (GOLD STANDARD): especially when done with hysteroscopy, uterine dilation, and curettage can be diagnostic and therapeutic

Q

How is an ectopic pregnancy dx?

A
  • Beta HCG is >1,500, but no fetus in utero
  • serial increases of betaHCG are less than expected (should double every 2 days); get baseline BetaHCG and follow-up hormone levels in 48 hours - if they are sub optimally rising (not doubling) then it is likely an ectopic pregnancy
  • when betaHCG is >1,500 = should show evidence of developing intrauterine gestation on ultrasound = if not, suspect ectopic transvaginal US >90% sensitive (IUP visible by 5-6 weeks)
  • ultrasound = ring of fire sign: the ring of fire sign also known as ring of vascularity signifies a hypervascular lesion with peripheral vascularity on color or pulsed doppler examination of the adnexa due to low impedance high diastolic flow

Q

What’s the tx for an ectopic pregnancy?

A

methotrexate = only if beta HCG <5,000, ectopic mass is <3.5 cm, no fetal heart tones, hemodynamically stable, no blood disorders, no pulmonary disease, no peptic ulcer, normal renal function, normal hepatic function, compliant pt that can return for follow up

  • administration fo methotrexate is the appropriate treatment for an ectopic pregnancy unless there are contraindications to use the drug
  • these contraindications include current breast-feeding, active pulmonary disease, immunodeficiency, or hypersensitivity to methotrexate
  • the drug is a folic acid antagonist that inhibits DNA replication
  • the effectiveness of administration is similar to surgical treatment without the risk of surgical complications
  • Indications for methotrexate therapy include a hemodynamically stable patient, hCG levels below 5,000 IU/L, mass <3.5 cm, no fetal cardiac activity, and the ability to comply with post-treatment follow-up
  • methotrexate can be administered intravenously, intramuscularly, or orally
  • It can also be injected into the ectopic pregnancy directly, although this route of administration is not commonly used
  • Intramuscular administration is the route of administration that is most commonly used for the treatment of ectopic pregnancy
  • surgical treatment: laparoscopy salpingostomy = emergent situations (rupture) or patient not meeting methotrexate criteria
  • follow-up testing = crucial

Q

What are the theories of DZ for endometriosis?

A
  • retrograde menstruation (most likely): endometrium floats back out of the Fallopian tubes onto ovary/into the cul-de-sac

Q

What is the tx of endometriosis?

A

medical or surgical

  • surgical: resect endometriosis
  • medical: NSAIDs, progestins, progestins, oral contraceptive therapy, danazol, NSAIDs, GnRH agonist (put in a state of pseudopregnancy)
  • can only give danazol for 6 months because of bone loss (can do longer if you do add-back therapy)
  • Increasing the consumption of long-chain omega-3 fatty acids can decrease a women’s risk of endometriosis
  • having multiple childbirths, extended periods of lactation, and the use of oral contraception may also decrease the risk

A

fetal vessel may lie over the cervix

55
Q

What is the presentation of placenta previa?

A

painless vaginal bleeding

  • usually occurs after 28 weeks of gestation
  • bleeding from placenta previa results from small disrputions in placental attachment during normal development and thinning of the lower uterine segment during third-trimester = may stimulate further uterine contractions = further placental separation and bleeding

strict pelvic rest (no intercourse) and modified bed rest, no vigorous exercise

  • blood transfusion may be necessary so get a type and screen if you discover previa via U/S
  • c-section is preferred delivery
  • give Rhogram if Rh-
  • some studies show that delivery between 34-37 weeks may be optimal
59
Q

What is non-stress testing?

sudden “gush” of clear or pale yellow fluid from the vagina that occurs after 37 weeks of gestation

64
Q

What is premature rupture of membranes dx?

A

What is mastitis?

A

a regional infection of the breast from skin flora or oral flora of breastfeeding baby - organisms enter erosion or cracked nipple; the main cause is clogged milk ducts

  • occurs mainly in breastfeeding women
  • usually caused by nipple trauma
  • unilaterl erythema, tenderness, usually one quadrant of the breast affected, fever and chills
  • congestive (bilateral) vs. infectious (unilateral)
  • usually caused by S. auresu
92
Q

What is the tx for mastitis?

A

if infectious treat with dicloxacillin, cephalexin, or erythromycin for staph alternate is clindamycin
-continue to breastfeed on the affected side along with warm heat 4 times per day

93
Q

What is a breast abscess?

A

a pocket of contained infection within the breast

  • a progression from mastitis - symptoms are the same with the addition of localized mass and systemic signs of infection
  • staphylococcus aureus is the most common cause
94
Q

How is a breast abscess tx?

A

I&D and anti-staph antibiotics

  • regimen: nafcillin/oxacillin IV or cefazolin PLUS metronidazole
  • alternative is vancomycin
  • stop breastfeeding on the affected side - pump and dump
95
Q

What are the ddx of vaginal discharge?

A

yeast infection, BV, HPV, trichonmoniasis, herpes, cervicitis, foreign body (tampon), sexually transmitted infections (STIs), such as chlamydia or gonorrhea, various sex practices, vaginal medicines/douching, menopause, vaginal discharge, an absence of menstruation, anxiety

96
Q

What is an ovarian cyst?

A

an ovarian cyst is a fluid-filled sac within the ovary

  • the majority of cysts are harmless and cause no symptoms
  • occasionally they may produce bloating, lower abdominal pain, dyspareunia, or lower back pain
  • ovarian cysts may be classified according to whether they are a variant of the normal menstrual cycle (functional) or non-functional
  • follicular cysts are the most coomon
97
Q

What are the characteristics of functional cysts?

A

(3 types): normal physiologic functioning of ovaries = follicular (MC) and corpus luteum; 2-3 cm can get as big as 10 cm, clear serous liquid, smooth internal lining

  • follicular cyst (the most common type): a dominant follicle fails to rupture
  • corpus luteum: dominant follicle ruptures but closes again and doesn’t dissolve
  • theca lutein cysts: overstimulation of HCG produced by placenta so only seen in pregnancy
98
Q

What are non-functional cysts/neoplastic cysts?

A

PCOS (amenorrhea, hirsutism), endometriomas (chocolate cysts), dermoid cysts (teratoma), ovarian serous and mutinous cystadeoma, etc.
->10 cm, irregular borders, internal septations

99
Q

What are the complcations of ovarian cysts?

A
  • hemorrhagic: more common with follicular and corpus luteal cysts
  • rupture: release contents into peritoneal cavity, frequently after sexual intercourse
  • torsion: ovary twists around suspensory ligament, cuts of blood supply to the ovary (risk if the cyst is >5 cm)
100
Q

What is the hx of a patient with ovarian cysts?

A

follicular tend to be asymptomatic, larger = pelvic pain; corpus luteum = local pelvic pain, amenorrhea, or delayed menses

101
Q

What is the PE of ovarian cysts?

A

ruptured = pain, low blood pressure, abdominal or shoulder pain, tachycardia; torsion = waxing and waning pain, n/v, low-grade fever

  • abdominal and pelvic ultrasound is the first imaging study of choice for suspected ovarian torsion because it is less expensive than and has similar diagnostic performance as computed tomography (CT) and magnetic resonance imaging (MRI)
  • definitive diagnosis is direct visualization of a tossed ovary during surgery, and prom operative evaluation is the mainstay of treatment to preserve ovarian function
102
Q

How is ovarian cyst dx?

A

transvaginal ultrasound/abdominal

  • MRI: if ultrasound indeterminate for surgical resection evaluation
  • labs: serum CA-125 (in menopausal, postmenopausal individuals) = assists in ruling out ovarian cancer
  • histologic analysis via ultrasound-guided aspiration (definitive)
103
Q

What is the tx of ovarian cyst?

A

treatment is based on type and size

  • < 5 cm observation is the mainstay (function, endometriomas, serous and mutinous adenomas)
  • uncomplicated cyst rupture (hemodynamically stable): expectant management and NSAIDs
  • > 5 cm cyst is removed by laparoscopy
  • surgery indicated if benign but symptomatic tumors, malignant tumors, cysts that are hemorrhagic severely, and ovarian torsion
104
Q

What is bacterial vaginitis?

A

lack of lactobacilli = low hydrogen peroxide = high pH (>4.5); infection is polymicrobial (mostly gardnerella Vaginalis)
-sxs: thin discharge, fish odor

105
Q

How is bacterial vaginitis dx?

A

milky vaginal discharge, pH >4.5, amine “whiff” test (fishy odor), clue cells (gram-negative)
-AMSEL criteria: thin, white homogeneous discharge, presence of clue cells in microscopic exam (striped epithelial cells), pH >4.5, fishy odor - must have 3/4

106
Q

What is the tx for bacterial vaginitis?

A

metronidazole (PO or intravaginally) OR clindamycin = recurrence is common d/t biofilm production - may need prolonged tx (6 mos.)

107
Q

What is candidiasis?

A

infectious of the vaginal tract with candida (MC is albicans)

  • sxs: itching/burning, dyspareunia, thick white discharge, beefy red vaginal mucosa
  • diabetes mellitus is a predisposing factor for recurrent vulvovaginal candidiasis since hyperglycemia enhances the ability of Candida alicans to bind to vaginal epithelial cells
108
Q

How is candidiasis dx?

A

wet mount = KOH and saline + microscopy; pH <4.5 (normal) BD affirm = DNA test; yeast cs if recurrent (look for different type of yeast)

109
Q

What is the tx for candidiasis?

A

fluconazole (150 mg PO x 1) - if it’s really bad, can give another dose 72 hours later, vaginal cream (miconazole, terconaxole, clotrimazole, etc) - 7 day course typically works better

110
Q

What is trichomonas?

A

caused by parasitic protozoan trichomonas vaginalis; can affect fertility so we want it treated well
-sxs: men are usually asymptomatic; females: itching, burning, post-coital bleeding, dysuria, frothy white/grey discharge

111
Q

How is trichomonas dx?

A

saline wet mount a must look at very quickly (parasites die fast); pH>/= 4.5; BD affirm, strawberry cervix on spec exam (only present ~1-% of time but is pathogomonic

112
Q

What is the tx for trichomonas?

A

metronidazole (PO only)
-partner: tx warrants full STI screening, pt should be retested in 2 weeks - 3 los. to ensure successful tx (“test of cure”)

113
Q

What is atrophic vaginitis?

A
  • Def: atrophy of vaginal and vulvar tissue d/t hypoestrogenic state (often seen in menopause)
  • Sxs: dryness, burning, irritation, low lubrication, pain/discomfort w/sex, urinary urgency, dysuria, recurrent UTIs
114
Q

What is the PE of Atrophic vaginitis?

A

fragile tissue, fissures, petechiae, labia minora resorption, loss of moisture and rug and elasticity, prominent meatus, urethral eversion or prolapse

115
Q

How is atrophic vaginitis dx?

A

clinical

116
Q

What is the tx for atrophic vaginitis?

A

first-line therapy for symptomatic relief of vulvovaginal atrophy is with non-hormonal vaginal moisturizers and lubricants

  • If therapy does not result in symptom relief, low-dose vaginal estrogen (insert, ring, cream) therapy may be used if the woman has no contraindications (estrogen-dependent malignancy)
  • sexual activity and/or use vaginal dilators can help maintain healthy vaginal epithelium
  • prescribing a vaginal ring that contains 2 mg of estradiol to be placed once every 3 months is an appropriate initial intervention for patients with symptoms of post-menopausal vaginal atrophy
  • a daily intravaginal estradiol tablet is also effective
