Gynaecological Infections
Physiologic Discharge
• clear, white, flocculent, odourless discharge; pH 3.8-4.2
• smear contains epithelial cells, Lactobacilli
• increases with increased estrogen states: pregnancy, OCP, mid-cycle, PCOS, or premenarchal
• if increased in perimenopausal/postmenopausal woman, consider investigation for other effects of
excess estrogen (e.g. endometrial cancer)
Non-Physiologic Discharge
• etiology
genital tract infection
vulvovaginitis:candidiasis, trichomoniasis,BV, polymicrobialsuperficial infection
chlamydia, gonorrhea
pyosalpinx,salpingitis
• genital tract inflammation (non-infectious)
local: chemical irritants, douches,sprays,foreign body, trauma, atrophic vaginitis,desquamative
inflammatory vaginitis, focal vulvitis
neoplasia: vulvar, vaginal, cervical, endometrial
• systemic: toxic shock syndrome,Crohn’
s disease, collagen vascular disease, dermatologic (e.g.
lichen sclerosis)
IUD,OCP (secondary to progesterone)
Vulvovaginitis
PREPUBERTAL VULVOVAGINITIS
• clinical features: irritation, pruritus, discharge, vulvar erythema, vaginal bleeding (can be due to
(iroup A Streptococcus and Shigella )
• etiology
• non-specific vulvovaginitis is responsible for 25-75% of vulvovaginitis in prepubertal girls
• there are a number of potential factors in children that increase the risk of vulvovaginitis:
lack of labial development
non -estrogenized, thin mucosa
more alkaline pH (pH 7) than postmenarchal girls/women
obesity
poor hygiene (proximity of anusto vagina)
foreign bodies (most commonly toilet paper)
irritation by bubble baths,shampoos,perfumed soaps, and chemicals
localized skin disorders:lichen sclerosis,condyloma acuminata
trauma:accidentalstraddle injury,sexual abuse
infectious
Vulvovaginitis
Vulvar and vaginal Inflammation
Vulvar Hygiene
Recommend wipe front to back,
wash vulva only with water, avoid
daily pantyliners. avoid douching, no
need for "feminine cleansers/sprays/
powders",use gentle laundry detergents
for underwear, cotton underwear, no
underwear at night
pinworms
Candida (if using diapers or chronic antibiotics)
Group A Streptococcus, S.aureus,and Shigella
discovery of STI should raise suspicion ofsexual abuse
Prepubertal and Adolescent
Gynaecological Infections:Legal
Aspects of Confidentiality
. Clinicians who treat adolescents
must be aware of federal, state, and
provincial laws related to adolescent
consent and confidentiality
• Clinicians must be aware of
guidelines governing funding sources
for particular services and be familiar
with the consent and confidentiality
policies of the facility In which they
practice
other
polyps,tumour (ovarian malignancy)
psychosomatic vaginal complaints (specific to vaginal discharge)
endocrine abnormalities (specific to vaginal bleeding)
blood dyscrasia (specific to vaginal bleeding)
other systemic diseases: measles, chickenpox,scarlet fever, Hpstein-Barr Virus, Mycoplasma
pneumonia-induced rash and mucositis, Stevens-lohnson syndrome,Crohn'
s disease, and
Kawasaki disease have all been associated with vulvovaginal signs and symptom
• investigations
• vaginal swab for culture (specifically state that it is a pre-pubertal specimen)
pH, wet
-mount, and KOH smear in prepubertal adults only
• treatment
r > enhanced hygiene and local measures (handwashing, white cotton underwear, use sitz baths, use
mild detergent, urinate with legsspread apart, no nylon tights, no tight-fitting clothes, no sleeper
pajamas, avoid bubble baths, eliminate fabric softener, avoid prolonged exposure to wet bathing
suits) to protect vulvarskin
• infectious: treat with antibioticsfor organism identified
Most common gynaecological problem
in prepubertal girls is non-specific
vulvovaginitis,not yeast

CHLAMYDIA
Etiology
• Chlamydia trachomatis
Epidemiology
• most common bacterial STI in Canada
• often associated with N.gonorrhoeac ( patients with chlamydia should also he tested for gonorrhea)
Clinical Features
• asymptomatic (80% of women)
• muco-purulent endocervical discharge
• urethralsyndrome:dysuria,frequency, pyuria, no bacteria on culture
• pelvic pain
• postcoital bleeding or intermenstrual bleeding (particularly if on OCP and prior history of good cycle
control)
• symptomatic sexual partner
Investigations
• cervical culture or nucleic acid amplification test (can present in pharynx, rectum)
• obligate intracellular parasite: tissue culture is the definitive standard
• urine and self vaginal tests now available, which are equally or more effective than cervical culture
Treatment
• doxycycline 100 mg PC) BID for 7 d or azithromycin 1 g PC) in a single dose
Doxycycline is contra-indicated in the 2nd and 3rd trimesters of pregnancy
• reportable disease, test and provide empiric treatment to all sexual partners of the index case within
60 d prior to symptom onset or dale of specimen collection (if the index case is asymptomatic)
• test of cure is recommended 3 wk after completion of treatment when compliance to treatment is
suboptimal, an alternative treatment regimen is used, experiencing persistent symptoms,or the
person is prepubertal or pregnant
Screening
• during pregnancy
• asymptomatic sexually active people under 25 yr
• neonates born to mothers with chlamydia
• any other people with risk factorsfor sexually transmitted and blood-borne infections

Complications
• PID: low-grade salpingitis and adhesions resulting in tubal obstruction
• infertility
• ectopic pregnancy
• chronic pelvic pain
• Fitz-Hugh-Curtissyndrome (liver capsule inflammation)
• reactive arthritis (male predominance, HLA-B27 associated), conjunctivitis, urethritis
• perinatal infection:conjunctivitis, pneumonia
GONORRHEA
Genital Warts During Pregnancy
• Condyloma tend to get larger in
pregnancy and should be treated
early (consider excision)
• Removal only if obstructing birth
canal or risk of extensive bleeding
• Do not use imiquimod, podophyllin,
or podofilox in pregnancy
• Baby at risk for juvenile respiratory
papillomatosis, but cone dissection
does not significantly reduce the risk
Etiology
• Neisseria gonorrhoea?
• symptoms and risk factors same as chlamydia
Investigations
• Gram stain shows Gram-negative intracellular diplococci
• cervical, rectal, and throat culture (if clinically indicated)
Treatment
• single dose of ceftriaxone 250 mg IM plus azithromycin 1 g PO
if pregnant: above regimen or spectinomycin 2 g IM plus azithromycin 1 g PO (avoid quinolones)
• also treat chlamydia, due to high rate of co-infection
• treat partners
• reportable disease
screening as with chlamydia
Human Rights in Health Equity: Cervical Cancer

In developed countries due lo effective prevention
and treatment,socially disadvantaged women
within these countries remain disproportionately
more lively to develop and die olcervical cancer.
• In most develop ng countries cervical cancer rates
have risen or remained unchanged.
• It must be recognized that cervical cancer
disparities between race groups,urban and
rural residence.and high and low socioeconomic
status are attributed to dispaiate screening and
vaccination coverage.

HUMAN PAPILLOMAVIRUS
Etiology
• most common viral ST'
l in Canada
• >200 subtypes, of which >30 are genitalsubtypes
• HPV types 6 and 11 are classically associated with anogenital warts/condylomata acuminata
• HPV types 16 and 18 are the most oncogenic (classically associated with cervical HSIL)
• types 16, 18, 31, 33,35, 36, 45 (and others) associated with increased incidence of cervical and vulvar
intraepithelial hyperplasia and carcinoma
• HPV is readily transmissible between opposite and same-sex partners through receptive and
penetrative vaginal, anal and oral sex, and non-penetrative sex (digital-vaginal sex and skin-toskin contact)
infection with one HPV type does not appear to provide protection against infection with related
HPV types
Clinical Features
• latent infection
no visible lesions, asymptomatic
only detected by DNA hybridization tests
• subclinical infection
visible lesion found during colposcopy or on Pap test
• clinical infection
visible wart
-like lesion without rnngniAcation (check pharynx too)
hyperkeratotic, verrucous or flat, macular lesions
• vulvar edema
A 9 Valent HPV VaccineAgainst Infection and
Intraepithelial Neoplasia in Women
NEJM 2015:372:711-723
Purpose: lodetermine the efficacy and
immunogen city of the qHPV (types 6,11,16.18)
vs.9vHPV (five Jddtonal types 31.33.45.52. 58)
vaccines.
Method itteinalio-alrandonnted. double-blinded
phase 28-3study of 9vHPV va tc me i n 14215 worn eu
between agesol 16-26. Participants were random it ed
lo the 9rHPV vaccmegroup or the qHPIf vaccine group
and each recerr ed a series of three IM inactions(d
1.2 mo. and 6 mo).Swabs ol labial,valvar, perineal,
perianal, endocenrical.and ectocervical tissue was
obtamedend used for HPV DMA testing/Pap smear.
Results:Pate ol high-grade cervical,vulvar, or
va gi nal disease was14.0 per1000 person-yr in both
vaccinegroups.Tbe rate of bigh-grade cervical,
vulvar, or vagnal disease related to HPV-31,33.45.
52. and 58 was 0.1 per 1000 person-yr in the 9vHPV
group and1.6 per1000 person -yr in the qHPV group
(95% CI-80.9-99.81. Antibody responses to HPV-6,11,
16.and 18 were not sign ficantly different between
the two vaccine groups although adverse events
related lo injection vies weie more common n the
9vHPV group.
Conclusions the9iHPV vaccine was non-inferior
to qHPV vaccine in prevent ng infection and disease
related to HPV-6.11.K.and 18and also coveved
additional oncogen c types KPV-31.33.45.52. and 58
in a susceptible popnlabon.
Investigations
• cervical cytology by Pap test
• koilocytosis: nuclear enlargement and atypia with perinuclear halo
• biopsy of lesions at colposcopy
• detection of HPV DNA subtype using nucleic acid probes (not routinely done but can be done in
presence of abnormal Pap test to guide treatment)
Treatment
• anogenital svarts
• patient administered
podofilox 0.5% solution or gel BID x 3 d in a row (
-1 d off ) then repeat x 4 wk
imiquimod (Aldara*) 5% cream Jx/wk nightly x 16 wk
sinecatechins 10% ointment 0.5 cm strand T ID x up to 16 wk, daily dose 250 mg ( need not
be washed off )
