Q

how does vulvar lichen sclerosus present? what is the general progression of symptoms? (7)

A
  1. first, erythema & edema
  2. WHITE PLAQUES
  3. intense “ITCH-SCRATCH” CYCLE … leading to telangectasias and subepithelial hemorrhages… leading to erosions/fissures/ulcerations
  4. thin wrinkled, white skin (CIGARETTE PAPER SKIN)
  5. agglutination (sticking together) of labia minora –> phimosis over clit
  6. contraction of vulvar structures –> introital stenosis

Q

why is vulvar lichen sclerosus harderto diagnose in younger children?

A

can present as shiny/waxy skin

  • hypopigmentation harder to see on natural pale young skin

25
what are the 6 Ps of lichen planus?
``` Pruritus Polygonal Planar Purple Papules Plaques (but the moist environment and walking around can really alter the morphology of the primary lesions here) ```
26
generalized glazed erythema, Some erosions, beginning loss of clitoris and labia minora. what is this?
advancing vulvovaginal lichen planus
27
treatment of vulvovaginal lichen planus?
initial then step-up.. 1. topical: vaginal hydrocorticone foam 2. stronger corticosteroids 3. tacrolimus cream 4. systemic steroids * careful exam for formation of adhesions.. may need vaginal dilators
28
vulvitis from menopausal atrophy: 3 main characteristics?
- enlarged clitoris - shiny atrophic vestibule - loss of hair
29
vulvitis from severe ulcerative allergic contact dermatitis: 2 characteristics
- severe, generalized erythema & swelling | - erosions, and extensive ulceration
30
vulvitis txt is diagnosis-specific but in general, what are the txt guidlines? (3)
1. txt underlying infection (if there is one) & avoid irritants 2. sitz baths 3. steroids (medium potency)
31
Most common STI in the world?
HSV
32
how is most HSV spread? ( at what percent?)
~70% transmitted via asymptomatic viral shedding
33
HSV vulvovaginitis symptoms
Prodrome: itching or tingling, constitutional (effect many body systems) - Multiple, small, painful blisters then . . . Shallow ulcers -Crusts over in 7-10 days
34
recurrences of HSV in what percent of cases? (maybe weeds)
50%
35
Dx of HSV: what is good and what isnt?
clinical (multiple vesicles/ulcers, PAINFUL), then ELISA to type it - tzank smear, DNA PCR, and viral cultures ARE NOT sensitive enough
36
txt for HSV
symptomatic: topical barriers, analgesics (xylocaine) systemic- NSAIDS + narcs sitz baths anti-virals: "-cyclovirs"
37
3 kinds of vaginitis/vaginosis and what causes each?
Bacterial Vaginosis: Gardnerella Candidiasis: Candida albicans Trichomonas: Trichomonas vaginalis
38
most common cause of vaginal discharge in women of reproductive age. also found in ___% of asymptomatic women
BV , 40%
39
what is BV?
alteration of normal vaginal flora (lactobacilli) | increase # anaerobes (which produce ammines)
40
what is Amsel's criteria for BV?
need 3 of the 4... 1. a thin, homogeneous, white, non-inflammatory adherent discharge 2. clue cells (make up at least 20% of all epithelial cells seen) 3. vaginal pH of ≥4.5 4. positive “whiff” test: a fishy odor after adding KOH
41
what are clue cells?
gardnerella vaginalis bacteria taking up 75% of the border of epithelial cells (in BV)
42
3 txt options for BV
1. flagyl PO 2. flagyl topical (metroGel) - intravaginal 3. 2% clindamycin cream - intravaginal
43
what is vaginal candidiasis ?
yeast part of normal flora of vagina (present in 25-50% of healthy patients. BUT an overgrowth leads to this yeast infection

spores and hyphae
48
yeast infection txt
antifungals : azoles | 2nd line- nystatin (suppository- cheap)

why do you need systemic therapy for trich?
infection can be multifocal, involving vaginal epithelium, the urethra, or perivaginal glands such as Bartholin’s or Skene’s glands.
56
what is bratholin's cyst/abscess?
bartholin's glands: bilateral in labia minora | -usually pea-sized, can become cystic (blocked and fluid filled)and form an abscess
57
what age group do bratholin's cyst/abscess usually present in? fast or slow onset?
fast, women 20-30yo | *usually delay in seeking care so by the time they show up, they area abscesses

59
bartholin's abscess txt (3 part process)
1. local anesthesia & sterile prep. incision 1-1.5cm long (from INSIDE the labia) 2. hemostat to break up loculations 3. word catheter placed to drain
60
do NOT txt barthonlin's abscess with what?
antibiotics!
61
most common cause of STIs and cervicitis?
GC and chlamydia
62
how many cases of chlamydia a year (maybe weeds)
1.2 million
63
STI/cervicitis presentation (7)
dysuria, frequency, urgency, pelvic pain,VAGINAL BLEEDING, and vaginal discharge

Mucopurulent cervicitis is often _______
asymptomatic.
65
is mucopurulent discharge sensitive predictor of GC or chlamydia infection?
no, most patients with these infections actually do not present with mucopurulent discharge.
66
pelvic exam for STI/cervicitis
may reveal a tender, friable cervix with mucopurulent discharge but can be completely normal
67
Dx of cervicitis
mostly presumptive | cervical swab & culture
68
Txt of cervicitis- gonorrhea
250mg IM rocephin (ceftriaxone) or 400mg PO cefixime (amox or erythromycin if allergic)
69
txt of cervicitis- gonorrhea but pregnant?
same txt as if not pregnant.... | just NO quinolones or TCN
70
txt cervicits- chlamydia
single dose azithromycin or doxycycline - amoxicllin if pregnant - erythromycin if allergic
