ICL 9.2: Benign Diseases of the Vagina/Vulva Flashcards
(30 cards)
what are some of the symptoms of vaginal discharge?
- itching
- irritation, burning
- malodorous discharge
- odd appearance of vaginal discharge
associated symptoms: fever, dysuria, pelvic pain, post-coital bleeding
what are signs of bad vaginal discharge during a pelvic exam?
- friable cervix (when you touch cervix it bleeds)
- abnormal appearing vaginal discharge
- adherent to sidewalls
- clumped, discharge at introitus
what does a normal premenopausal vagina look like?
- pink, rugated vaginal tissue
- pH < 4.5
- non-keratinized epithelium
- responsive to hormones
- normal microbiome with a 5:1 aerobic:aerobic ration
- normal vaginal secretions that are white and usually in posterior fornix –> increase in thin clear mucuous from the cervix midcycle
why is it important that the vagina responds to hormones? specifically estrogen
- estrogen increases glycogen in the cells which makes glucose available to the normal bacteria of the vagina which allows for the formation of lactic acid from the bacteria which makes the normal acidic environment of the vagina!
- maintains the elasticity and normal epithelial thickness
38 year old with increased itching and discharge for 1 week. discharge is different from the past in that it is white, clumped and without odor. she hasn’t tried anything over the counter to treat
PMH: BMI 45, 24 weeks pregnant
PE: no abdominal tenderness, vagina with white, clumped discharge and white plaques on vaginal walls but otherwise normal, vaginal pH is 4.0
which conditions are in your differential? what is the most likely diagnosis?
- BV
- candidiasis
- trichomonas
- allergic/contact (not common for this presentation)
she probably has candidiasis!
treat with vaginal metronidazole instead of a oral azole because she’s pregnant so that way you limit exposure of the baby to drugs
what are the risk factors for yeast infection?
- uncontrolled diabetes
- pregnancy
- immunosuppression/on steroids
- antibiotics (get rid of normal vaginal biome and why you shouldn’t douche)
what is a complicated yeast infection?
someone who has DM and a yeast infection has a complicated yeast infection and you need to treat differently
what does a vaginal candidiasis infection look like?
thick, white, clumpy
adherent to the cervix
not thin or homogenous
what tests do you do for a candida infection?
- wet mount
take a q-tip and sample the posterior fornix to get some of the discharge and put a drop of normal saline on it and then look under the microscope right there with the patient and can give them the diagnosis right there!
- DNA testing to send to lab
comes back within 24 hours; checks for BV, candidiasis and trichomoas but it’s $600 and takes time so wet mounts are better
what does candida look like under wet mount?
segmented pseudohyphae like bamboo!
little buds on the end
also looks like there’s snowmen everywhere aka a single ball that’s budding into 2
how do you treat candida?
- oral fluconizoles
- topical azoles
- vaginal metronidazole
non-pseudohyphae candida probably isn’t candida albicans and it isn’t as susceptible to normal candida treatment
what is bacterial vaginosis?
overgrowth of vaginal bacteria
NOT inflammatory so there’s barely any leukocytes!!! (in candida you get a lot of WBCs)
elevated pH greater than 4.5
what is the KOH test?
drop KOH on specimens and it releases putramines – any time you make the pH more alkaline, it releases putramines and it smells really bad
this is the whiff test!
used to diagnose bacterial vaginosis
what is a clue cell?
sign of bacterial vaginosis
looks like the edges of the cell are totally obliterated and it kinda looks like the whole cell is made of snow
what is important when it comes to educating patients about trichomonas infections?
partner needs to be treated as well because it’s an STD!! this is unlike candida and BV
flagellated protozoa that roll and tumble across the screen
inflammatory infection so tons of WBCs will be present
also check the patient for other STDs!!! gonorrhea, syphilis, HIV, HepB, chlamydia
24 year old at 16 weeks pregnant. new partner 8 weeks ago. no cramping or bleeding. presents with genital sores. no complaints or concerns though.
primary syphilis
bilateral chancers aka non-tender lesions which is different than HSV lesions which are super painful
look for hyper pigmented, papulosquamous rash of the palms and if they’re there it would make it secondary syphilis – primary syphilis can be less widespread and tends to just be one dominant lesion and if there’s more than 1, it means there’s a matching lesion on the other side
is syphilis contagious?
secondary syphilis lesions on the hands are highly contagious!!
how would you diagnose syphilis in this patient?
- direct testing of the lesion
- dark field microscopy
- some local lads have validated PCR tests for T pallidum
- biopsy with silver stain
- serology
- primary serology is often negative (2-4 weeks after exposure so IgG hasn’t formed yet)
- treponemal serology (TP-PA, FTA-ABS): specific to syphilis, will always stay positive once they’re positive
- non-treponemal (RPR, VDRL): used as titers, used to monitor response to treatment, can revert back to negative after treatment, can be positive for other treponemal diseases like YAWS
what should be in your differential if you think a lesion is syphilis and how do you differentiate?
- molluscum contagiosum
can be literally anywhere on the body, bumps have little pits in the middle
- HSV
highly inflammatory, shallow, painful ulcer
- condyloma acuminata (genital warts, have cauliflower appearance, can be different colors)
what is primary vs secondary vs tertiary syphilis?
PRIMARY
- 10-60 days after acquisition
- charmer at the site of entry that heals spontaneously
- serology negative
secondary
- 4-8 weeks after chancre appears
- rash, maculopapular
- condyloma lata
- resolves in a few weeks to months
TERTIARY
- cardiac, CNS manifestations
- gumma formation
1-2% of patients with secondary syphilis will have neurosyphilis; patients with HIV that also have syphilis have a really high chance of this happening to them
how do you treat syphilis? why is a certain treatment mandated for pregnancy?
- benzathine penicillin IM
alternative is oral tetracycline or doxycycline but the mandated treatment in pregnancy is penicillin because the spirochete crosses the placenta! so you can have congenital effects of having syphilis like mulberry teeth, syphilis rhinitis, etc. so you need to give penicillin which crosses the placenta and would make sure the baby is treated too! if someone has a penicillin allergy and they’re pregnancy you still treat them with penicillin you just desensitize them!
how do you diagnose herpes?
- PCR of lesion
- serology to see if patient has IgG which will be different for HSV1 vs HSV2
primary has no IgG conversion yet but secondary outbreak would have IgG
how do you treat herpes?
once you have herpes you have it forever, you are just trying to control outbreaks and protect your partner so you need to counsel!!!!
58 years old female present with vulvar irritation and discomfort. menopause at 52.
this vulvar irritation started 1 year ago and they’re worsening. she’s tried oatmeal baths and uses vaginal estrogen because she had painful intercorse
differential?
- lichen sclerosis
- lichen planus
- contact dermatitis
