What is bacterial vaginosis?
overgrowth of predominately anaerobic organisms eg Gardnerella Vaginalis.
leads to consequent fall in lactic acid = produces aerobic lactobacilli = raised vaginal ph
is Bacterial vaginosis (BV) STI?
NO but almost only seen in sexually active women.
features of bacterial vaginosis
vaginal discharge : “fishy” offensive
asymptomatic in 50%
What is amsels criteria?
used for?
used for bacterial vaginosis
diagnosis of BV - you need 3 of the following 4 :
- thin white homogenous discharge
- clue cells on microscopy- stippled vaignal epithelial cells
- vaginal ph > 4.5
- positive whiff test - addition of potassium hydroxide = fishy odour
how would you manage a BV patient?
asx: no tx. do swab. exception is if woman undergoing pregnancy termination
if symptomatic :
ORAL METRONIDAZOLE FOR 5-7 DAYS.
70-70% initial cure rate. relapse rate> 50% within 3 months.
if adherence issue: single oral dose metronidazole 2g.
topical metronidazole/clindamycin alternative
what pregnancy complications can BV have ?
results in increased risk of preterm labour, low birth weight and chorioamnionitis, late miscarriage
How to treat BV in pregnant pt?
previously they said no oral metronidazole in 1st trimester. NOW YOU CAN :)
TOPICAL CLINDAMYCIN TOO?
if asx: discuss with woman obstretrician
if sx: oral metronidazole 5-7 days or topical tx.
difference between BV and Trichomonasis?
BV: thin white discharge
TRI: frothy, yellow-green discharge
BV: microscopy :clue cells
TRI: wet mount: motile trophozoites
TRI: vulvovaginitis, strawberry cervix
similarities of BV and Trichomonasis?
offensive vaginal discharge
vaginal ph over 4.5
treat with metronidazole
what is trichomonas vaginalis?
highly motile flagellated protozoan parasite.
STI
features of trichomonas vaginalis
vaginal discharge: offensive, yellow/green, frothy
vulvovaginitis
strawberry cervix
ph> 4.5
in men: usually asx - could cause urethritis
investigations for trichomonas vaginalis
microscopy of wet mount: motile trophozoites
how would you manage trichomonas vaginalis?
oral metronidazole for 5-7 days.
could do one-off dose of 2g metronidazole
What is Vaginal Candidiasis ? (THRUSH)
common women condition.
80% cases of candida albicans - rest other candida species
predisposing factors for vaginal candidiasis ?
DM
drugs: abx , steroids
pregnancy
immunosuppresion: HIV
can just happen with no predisposing factors though.
features of vaginal candidiasis?
(white curdy vaginal discharge) cottage cheese - non offensive discharge - ph < 4.5
vulvitis: superficial dyspareunia, dysuria
itch
vulval erythema, fissuring, satellite lesions possible?
investigations of vaginal candidiais?
high vaginal swab not normally needed if clinical features are consistent.
how would you manage vaginal candidasis?
local/oral tx
oral flulconazole 150 mg - single dose - 1ST LINE
clotrimazole 500 mg intravaginal pessary - single dose - if oral therapy contraindicated
if vulval sx: consider adding topical imidazole in addition to an oral or intravaginal antifungal
if pregnant: only local tx : cream/pessaries - oral tx contraindicated
how would you define recurrent vaginal candidiasis?
BASHHH define - 4 or more episodes per yr
check compliance with previous tx
rule out differentials: lichen schlerosis
do bloods check DM
do high vaginal swab for microscopy and culture - confirm candidiasis
how would you treat recurrent vaginal candidiasis?
induction : oral fluconazole every 3 days for 3 doses
maintenance: oral fluconazole weekly for 6 months
What is Balanitis?
inflammation of glans penis
sometimes extending to underside of foreskin = balanoposthitis.
many causes: most common are infective ( bacterial and candidal). some autoimmune.
presentation can be acute or chronic. adults or children

improper washing under the foreskin
tight foreskin
if balanitis is caused by candidiasis tell me about it?
frequency
