Womens Health - Sexual Health Flashcards
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
what can make balanitis worse?
improper washing under the foreskin
tight foreskin

painless erosions
can be associated with reactive arthritis
how would you investigate balanitis
clinically diagnosed - use hx and physical appearance of glans penis
if infective cause suspected: swab for microscopy and culture - might show bacteria or Candida Albicans
if doubt about cause and extensive skin change: do biopsy
general treatment of balanitis
gentle saline washes
ensure wash foreskin properly
severe irritation and discomfort: 1% hydrocortisone for short period
if cause isnt clear these usually resolve condition
specific treatment of balanitis
candida: topical clotrimazole - 2 weeks to tx infection
bacterial : staphylococcus spp. or group b streptococcus spp. - oral flucloxacillin or clarithromysin if penicillin allergic
anaerobic balanitis: saline wash. topical/oral metronidazole if not settling
dermaitits/circinate: mild potency topic corticosteroid - hydrocortisone
lichen sclerosis/plasma cell balantis of zoon: high potency steroids - clobetasol
circumcision - helps lichen sclerosus
what is chancroid?
tropical disease
caused by haemophilus ducreyi.
painful genital ulcers : unilateral, painful inguinal lymph node enlargement.
ulcers:
sharply defined
ragged undermined border
What is chalmydia?
MC STI in UK
caused by chlamydia trachomatis. - obligate intracellular pathogen.
1/10 young women in uk.
what is the incubation period of chlamydia?
7-21 days
large percentage are asx
features of chlamydia?
asx for 70% women and 50% of men
women: cervicitis (discharge, bleeding), dysuria
men: urethral discharge, dysuria
potential complications of chlamydia
epididymitis
endometritis
pelvic inflammatory disease
infertility
reactive arthritis
perihepatitis (fitz-hugh-curtis syndrome)
increase incidence of ectopic pregnancy
how would you investigate chlamydia?
nuclear acid amplification tests (NAATs)
urine( 1st void sample), vulvovaginal swab or cervical swab - tested using NAAT technique
women: vulvovaginal swab - 1st line
men : urine test - 1st line
chlamydia testing: should be done 2 weeks after possible exposure
screening for chlamydia?
open to all men and women : 15-24
relies heavily on opportunistic testing
how would you manage chlamydia?
1st line : doxycycline 7 days .
if contrainidicated:
azithromycin (1g od for one day, then 500mg od for 2 days)
why is first line doxycycline rather than azithromycin?
concerns about mycoplasma genitalium.
this infection coexists with chlamydia - rising levels of macrolide resistance.
how would you treat chlamydia in pregnant women?
azithromycin, erythromycin or amoxicillin.
azithro 1g stat - drug of choice.
who would you let know if the pt has chlamydia
they should be offered choice of provider for initial partner notification: trained practise nurse or referral to GUM
men with urethral sx: all contacts since, and in the 4 weeks prior to sx onset
women and asx men : all partners from last 6 months or most recent sexual partner
what should you do for contacts of confirmed chlaymydia cases ?
offer tx prior to results of ix being known.
treat then test
What is lymphogranuloma venereum?
LGV
caused by chlamydia trachomatis serovars L1,L2,L3
risk factors of lymphogranuloma venereum
gay men
majority of pts who present in developed countries have HIV already
historically seen more in tropics
hiv + proctitis =
lymphogranuloma venereum
3 stages of infection for lymphogranuloma venereum
stage 1 : small painless pustule - later forms an ulcer
stage 2 : painful inguinal lymphadenopathy - may form fistulating buboes
stage 3 : proctocolitis
how would you treat lymphogranuloma venereum?
doxycycline
what bacterium causes normal chlamydia which leads to pelvic inflammatory disease and urethritis?
chlamydia trachomatis serovars d - k
