DISORDERS OF THE VULVA & VAGINA Flashcards
TYPES OF VAGINITIS
- bacterial vaginosis
- trichomoniasis
- candidiasis
VULVA is made up of ______________ squamous cell epithelium
keratinized
hair follicles
sebaceous glands
sweat glands
apocrine glands
– Occasionally contains breast tissue….may swell and become tender after delivery
VAGINA is made up of ______________ squamous cell epithelium
nonkeratinized
vaginal pH
3.5 - 4.5
vaginal flora is made up of
lactobacillus & other aerobic and anaerobic bacteria
normal vaginal secretions have NO ODOR
SYMPTOMS OF VAGINITIS
A change in the volume, color, or odor of vaginal discharge Pruritus Burning Dyspareunia Dysuria Spotting Erythema Pelvic discomfort
WHY IS IT IMPORTANT TO FIND THE ETIOLOGY OF VAGINITIS
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
be careful with physical exam of vaginitis, because with bacterial vaginitis, the vulva ______________
APPEARS NORMAL
if erythema, lesions or fissures are present = may suggest vulvar
dermatitis
PHYSICAL EXAM FOR VAGINITIS
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
pH testing for vaginitis - technique
swab with a pH swab or dry swab the WALL of the vagina, not pooled secretions
Use narrow range pH paper or swab (jen says to use pH paper of 4.0 - 5.0)
pH of premenopausal women
3.5 - 4.5 (jen says 3.8 - 4.5)
pH of bacterial vaginosis
> 4.5
pH of trichomoniasis
5.0 - 6.0
pH of candidiasis
4.0 - 4.5
in pregnancy, what does the amniotic fluid do to the pH of the vagina
amniotic fluid raises the pH
bacterial cultures of the vagina
ARE NOT HELPFUL
Saline wet mount for vaginitis
- evaluate within 20 minutes
Clue cells—bacterial vaginosis (BV)
Trichomonads
Increased PMNs—cervicitis
clue cells on saline wet mount indicate
BV - bacterial vaginosis
increased PMNs on saline wet mount indicate
cervicitis
KOH prep for vaginitis
to determine if fungal
see hyphae & budding yeast
what is the amine test
smelling the slide immediately after adding KOH for the “fishy” smell of BV or trichomonas
a positive amine test is indicative of
bacterial vaginitis
“fishy” odor after adding KOH to secretions = could be either BV or trichomonas
Most common cause of discharge of women of childbearing age (40-50%)
BV - BACTERIAL VAGINOSIS
Will be less lactobacilli present in conditions such as
yeast & bacterial vaginosis
Thin, white/gray discharge
bacterial vaginosis
what is bacterial vaginosis
Abnormality of the normal vaginal flora:
- Decrease in hydrogen-peroxidase lactobacilli
- Increase in primarily gram negative rods
bacterial vaginosis has a decrease in _________________ and an increase in __________
decrease in lactobacilli
increase in primarily gram negative rods
FINDINGS ON EXAM FOR BV
- fishy odor (both during exam & with KOH amine test)
- positive Clue cells on wet mount
- thin white/gray discharge
what is the usual complaint of BV
malodorous or copious discharge
BV itself does NOT cause symptoms of
Dysuria Dyspareunia Pruritis Burning Vaginal inflammation
- Up to 75% of BV infections may be
ASYMPTOMATIC
what criteria is used to diagnose BV
Amsel criteria
Amsel criteria for diagnosing BV
- need 3/4 of the following criteria to diagnose BV
1) Homogeneous, thin, grayish-white discharge that smoothly coats the vaginal walls
2) Vaginal pH > 4.5
3) Positive whiff-amine test
4) Clue cells on saline wet mount, comprising at least 20% of epithelial cells
treatment of choice for BV
METRONIDAZOLE (FLAGYL)
- oral = 500mg BID x 7 days (no alcohol)
- intravaginal gel 5g qd x 5 days
don’t have ________ while on metronidazole (flagyl)
alcohol
another treatment option for BV (after metronidazole)
CLINDAMYCIN
- oral or intravaginal
2 treatment options for BV
1) metronidazole (flagyl)
2) clindamycin
________ may be useful as adjunctive therapy for BV along with antibiotics
probiotics
do sexual partners also need to be treated when woman has BV
no
recurrence of BV
recurrence rates are high
May retreat with same or different regimen
Women who have 3 or more documented cases of BV in 12 months can be offered maintenance therapy:
metronidazole gel for 7-10 days then twice weekly dosing for 4-6 months
NOT clindamycin because of toxicity
women who have 3+ documented cases of BV in 1 year
treat with maintenance therapy of metronidazole
metronidazole gel x 7-10 days, then twice weekly x 4-6 months
do NOT give __________ for BV recurrences due to _____________
do not give CLINDAMYCIN for BV recurrences, due to toxicity
MOST COMMON STI WORLDWIDE
Trichomonas vaginitis
flagellated protozoan
trichomonas vaginalis
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
malodorous, thin, green/yellow vaginal discharge
trichomonas
SYMPTOMS OF TRICHOMONAS VAGINALIS
Malodorous, thin, green/yellow vaginal discharge (70%)
Burning, dysuria, frequency (urethra commonly involved also)
Pruritus, dyspareunia, pelvic discomfort
Post-coital bleeding
DIAGNOSIS OF TRICHOMONAS
On speculum exam MAY see green, malodorous, frothy discharge (<10%)
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
“STRAWBERRY CERVIX”
trichomonas
do partners of those infected with trichomonas need to be treated
yes
trichomonas treatment for men & non-pregnant women
Tinadozole (Tindamax)
2g x 2 days
or
Metronidazole (Flagyl) -
500mg bid x 7 day or 2g single dose
trichomonas treatment for pregnant women
metronidazole 2g single dose
trichomonas treatment for nursing women
2 g dose of Flagyl
BUT need to pump & dump x 24 hours after taking it
recurrent trichomonas infections are usually due to
Usually due to return to sexual activity too soon and reinfection
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
- desensitization is recommended if the patient is allergic
trichomonas treatment for HIV+ patients
⦁ 7 day course of either Tinadazole or Metronidazole
prolapsed bladder
cystocele
bladder bulges into the vagina
cystocele
why does a cystocele occur
This occurs when the supportive tissues & muscles between the bladder and the vagina weaken and stretch => bladder bulges into the vagina
