Normal vaginal discharge in reproductive
aged women
History of Presenting Complaint

Presence of blood
Relationship to the menstrual cycle
Associated symptoms
NATURE OF THE DISCHARGE
EXAMINATION
Patient is examined in the lithotomy
position
A speculum can be inserted
GONORRHOEA
CLINICAL FEATURES:
Endocervical mucopurulent discharge
When complicated with PID

Post coital and intermenstrual bleeding.
Pathogen – Neisseria gonorrhoeae
Mainly affect endocervix
50% of females are asymptomatic
I.P. 2-7 days

GONORRHOEA
COMPLICATIONS
Bartholin’s abscess Blisters near small
Pelvic inflammatory joints
disease Perihepatitis
Due to ascending infertility
infection Mother to child
Disseminated transmission
gonococcal infections Opthalmia neonatorum
Fever
Septic arthritis
INVESTIGATIONS
Microscopy of Gram stained endocervical smear
for Gonorrhea:
Gram negative intracellular diplococci
Rapid diagnosis
Culture for Gonorrhea
Thayer Martin medium- gray colonies
Nucleic acid amplification test (NAAT)
Vulvovaginal swab is used
TREATMENT

Partner tracing and Epidemiological
treatment to the partner
Avoid sexual relationships until both
partners complete treatments

Dysuria
Lower abdominal pain
Post coital and inter-menstrual bleeding.
Dyspareunia
Chlamydia trachomatis
Gram negative obligatory intracellular bacteria
Nearly 70% of females are asymptomatic
COMPLICATIONS
Pelvic inflammatory disease
Cause ectopic pregnancy and infertility
Perihepatitis
Sexually acquired reactive arthritis
In pregnancy
Pre-term births
Post-partum infections
Opthalmia neonatarum
INVESTIGATIONS
Microscopy (Not diagnostic nor
confirmatory)
Polymorphonuclear leukocytes > 30
under high power
In absence of intracellular diplococci
diagnosed as non gonococcal cervicitis
Nuclear amplification test (Diagnostic)
TREATMENT
Doxycyclin 100mg / bd for 7 days or
azithromycin 1g stat
Azithromycin during pregnancy
Partner tracing and Epidemiological
treatment to the partner
Avoid sexual relationships until both
partners complete treatments
TRICHOMONASIS
CLINICAL FEATURES:
Profuse frothy yellow/gray discharge with foul odor
Dysuria
Abdominal discomfort
Vulval itching
Dyspareunia
Rare – strawberry cervix (multiple hemorrhagic areas in cervix )
Trichomonas vaginalis
Most common STI worldwide
Flagellated protozoa
Mainly affects vagina, urethra and para urethral glands.
10- 50% of females are asymptomatic.
COMPLICATIONS
In pregnancy
Preterm birth
Low birth weight
SAMPLES
Secretions from the posterior fornix is
collected into the swab
Observe under microscope
INVESTIGATIONS
Microscopy:
Prepare wet smear (normal saline)
Observed for motile
Flagellated organism immediately
Staining with Giemsa
Culture:
Modified diamond TYM medium
TREATMENTS
Metronidazole 400mg – 500 mg / bd for 7
days
Partner tracing and epidemiological
treatment to the partner
Avoid sexual relationships until both
partners complete treatments
Vulvovaginal Candidiasis
CLINICAL FEATURES:
Thick white (curd like) non offensive vaginal discharge
Vulval itching
Vulval soreness
Superficial Dyspareunia (due to the vulval irritation)
Signs –
Erythema
Fissuring
Vulval oedema
Oval budding fungus
Pathogen – 80-92% Candida albicans
PREDISPOSING FACTORS
Diabetes mellitus
Long term steroids
Pregnancy
Prolonged antibiotic use
Immune suppression
SAMPLES: Vaginal swabs from lateral fornix
INVESTIGATION
Microscopy of vaginal smear
Gram stain or
wet film examination (KOH)
Hyphae and spores
Culture
Sabouraud agar medium
TREATMENT
Good hygiene
Remove predisposing factors
Oral Triazoles drugs- Fluconazole 150mg stat or
Itraconazole 200mg bd
Topical applications- Clotrimazole, Miconazole,
Nystatin
Pessaries and clotrimazole cream intravaginally
daily for 7-14 days
No epidemiological treatment for partner
BACTERIAL VAGINOSIS
CLINICAL FEATURES:
Greyish white homogenous vaginal discharge
Offensive fishy odor
No vaginal inflammation
Non- sexually transmitted infection
Frequent cause for vaginal discharge
Anaerobic or facultative aerobic bacteria
Normal vaginal flora of lactobacilli are replaced by
overgrowth of: Gardenerella vaginalis, Prevotella spp,
Mycoplasma hominis , Mobiluncus spp
Vaginal PH > 4.5
PREDISPOSING FACTORS
Vaginal douching
Oral sex
Smoking
Antibiotic use
Recent change in sex partner
IUCD
INVESTIGATIONS
Microscopy
Gram stained smear of vaginal discharge
(presence of clue cells)
DIAGNOSTIC CRITERIA
Presence of clue cells on microscopic examination
clue cells are epithelial cells covered with bacteria giving
a characteristic stipped appearance on examination
Yellowish grey discharge seen on naked eye
examination
Vaginal pH more than 4.5
Release of characteristic fishy odor on addition of
alkali
10% KOH
For diagnosis of bacterial vaginosis at
least three criteria should be present
TREATMENT
Metronidazole
400mg – 500 mg / bd for 7 days
Or 2g stat
Non-infective causes of vaginal discharge
Retained foreign bodies
Foul-smelling discharge
