Q
WHY IS IT IMPORTANT TO FIND THE ETIOLOGY OF VAGINITIS
A
It is important that laboratory documentation of the etiology of vaginitis be determined
Symptoms are very nonspecific
One CANNOT determine etiology from history and PE alone and may mistreat the condition
8
Q
be careful with physical exam of vaginitis, because with bacterial vaginitis, the vulva ______________
A
APPEARS NORMAL
9
Q
if erythema, lesions or fissures are present = may suggest vulvar
A
dermatitis
10
Q
PHYSICAL EXAM FOR VAGINITIS
A
Begin with careful external examination of the vulva:
- In bacterial vaginitis the vulva appears normal
- Erythema, lesions or fissures may suggest a dermatitis of the vulva
- Changes suggesting chronic inflammation?
May detect a foreign body
Note characteristics of vaginal discharge even though classic examples are not always the case
Check the cervix for erythema and discharge
Check for vaginal trauma
Bimanual exam to check for cervical motion tenderness and uterine tenderness
11

46
infects both men & women
trichomonas vaginalis
Female infections range from asymptomatic (50%) to acute, severe, inflammatory disease
Males are generally asymptomatic & the infection resolves spontaneously 90% of the time—the remainder get typical urethritis symptoms
Women can acquire the infection from men or other
infected women
men do not acquire it from other men
47
malodorous, thin, green/yellow vaginal discharge
trichomonas
48
SYMPTOMS OF TRICHOMONAS VAGINALIS

pH 5-6
Mobile T. vaginalis on wet mount (seen 60-70%)
Can do rapid antigen and nucleic amplification tests (usually available where prevalence is high)
On males…. can do PCR test on urine or a urethral swab…. trying to look for motile trich has VERY LOW yield

BUT need to pump & dump x 24 hours after taking it
55
recurrent trichomonas infections are usually due to
Usually due to return to sexual activity too soon and reinfection
56
how to treat recurrent trichomonas infections
⦁ may treat recurrent infections with Metronidazole 2g dose again or use 7 day course of 500mg BID of either Metronidazole or Tinadazole
⦁ If the above fails, can treat with 2g qd x 5 days
⦁ if still refractory - culture to see if strain is resistant
- in general, there is not a second line antibiotic

up to 1/3 of women develop yeast infxns from abx use
79
DIAGNOSIS OF CANDIDIASIS
o Speculum exam
⦁ thick, white, sometimes "cottage cheese" discharge
⦁ in severe cases = gray membrane
⦁ pH = 4.0 - 4.5
o KOH wet mount slide (up to 50% are negative) - but would see hyphae & budding yeast
o In rare cases, cultures for candida are indicated
⦁ multiple, recurrent, or persistent cases that are not responding to treatment (may have a resistant pathogen)
⦁ women with a normal pH, and no visible pathogen on wet mount

atrophic vaginitis can occur in
women of any age who experience a decrease in estrogenic stimulation of urogenital tissue
108
the effect of estrogen stimulation on urogenital system
- maintains a well-epithelialized vaginal vault
- estrogen acts on receptors in the vagina, vulva, urethra & trigone of the bladder
- estrogen maintains the collagen content of epithelium
- keeps epithelial surfaces moist
- maintains optimal genital blood flow
- maintains acidic vaginal pH (without estrogen, pH > 5)
109
RISK FACTORS FOR ATROPHIC VAGINITIS

120
treatment of Bartholin's duct cysts
- treatment not necessary in women < 40 unless they become infected or symptomatic
- if the cyst is large & not resolving = can then treat with the same technqiues you would use for an abscess
121
most Bartholin's duct cysts are
asymptomatic
122
symptoms of Bartholin duct abscess

- on exam = erythematous, warm, tender and usually fluctuant (can push around)
- there may be surrounding cellulitis
123
INFECTION of Bartholin duct abscess
usually polymicrobial
STIs are LESS likely - but still test pt if they are at high risk for STIs
There has been a rise in MRSA as etiologic agent
124
treatment of Bartholin's duct cyst or abscess
I&D - lance at or behind the hymenal ring
- place a wick to continue drainage;
- place a word catheter into the cavity and leave it in for at least 4 weeks
125
Marsupialization of Bartholin duct cyst/abscess
- longer procedure done under local anesthesia
- reserved for patients who fail 1-2 placements of a word catheter
- procedure = cut slit into cyst/abscess and suture down edges - makes recurrence less likely
- Complications = hematoma, scarring, dyspareunia
