Vaginal Conditions Flashcards
At puberty, due to estrogen, the vaginal lining changes to ___________, which contains glycogen
stratified squamous epithelium
_______ uses the glycogen of the vagina to form lactic acid. This creates an acidic pH between 3.5 - 5.5
Lactobacillus bacteria
What is the purpose of the acidic environment in the vagina?
- the acidity helps maintain the normal vaginal flora and inhibitors the growth of pathogenic organisms
What changes to the environment of the vagina after menopause?
- thinning of the vaginal lining occurs, lactobacilli decline and the pH rises
What are the factors that influence the vaginal flora, pH and glycogen concentration include what?
- aging
- menstrual cycle hormonal fluctuations
- certain diseases- diabetes mellitus (increase of sugar peeing out)
- various medications (antibiotics)
- douching
- number of sexual parters (increases exposure to additional organisms)
What should be done to clean the vagina?
- vagina is self-cleaning through secretions and has protective substances (NO concern about vaginal cleanliness)
What are the adverse effects associated with douching?
- disruption of normal vaginal flora, increased risk of irritation or infection
- risk of genital tract infections, ectopic pregnancy, potential cervical cancer risk
- may prevent detection of infection
Douching is associated with what in pregnancy?
- preterm births, low birth weight infants and decreased fertility
What should douching be avoided in?
- avoid in pregnancy, use as a contraceptive or as a self treatment of vaginal infections, 24-48 prior to gynecologic exams and at least 3 days after last dose of a vaginal anti fungal medication

- avoid vaginal sprays and deodorants
- change out of damp swimwear and sports clothing
- avoid long exposure to conditions that are hot and cause sweating
- wipe front to back after using the toilet
What is bacterial vaginosis?
- imbalance in the normal vaginal flora
- increased growth in organisms (aerobic bacteria) normal found in the genital tract and a decrease in lactobacilli
What are the complications associated with bacterial vaginosis and pregnancy?
- 2nd trimester miscarriage
- pre-term birth
- pelvic inflammatory disease
What are the risk factors associated with bacterial vaginosis?
- more common if sexually active
- new sexual partner
- IUD
- douching
(this is NOT sexually transmitted however)
What are the signs of bacterial vaginosis?
- thin, off-white/yellow or grey discoloured discharge
- vaginal pH of 5-6
What are the symptoms of bacterial vaginosis?
- fishy odour (can be stronger after sex)
- can be asymptomatic
- minimal itching
- LACK of inflammation- therefore there is no experience of dysuria or painful intercourse
Is bacterial vaginosis a referral?
YES
What is the treatment for asymptomatic BV?
- treatment is not required unless
- high risk pregnancy
- prior to IUD insertion or gynecological procedures
What is the treatment for symptomatic BV?
- requires rx treatment
- can use oral metronidazole, oral clindamycin, clindamycin 2% vaginal cream, or metronidazole 0.75% gel
What is the efficacy of yoghurt or L. acidophilus in treating bacterial vaginosis?
- lack of evidence for efficacy
Does the male partner require a treatment for BV?
- no
What is considered a recurrent vaginal infection?
- infection is considered recurrent if it occurs within 1-3 months of previous treatment, occurs in 15-30% of patients
- diagnosis must be reconfirmed by a physician (for BV)
What is the recommended treatment options for a recurrent BV infection?
- metronidazole 500 mg po bid for 10-14 days
- metronidazole gel 0.75%, one applicator once a day intra-vaginally for 10 days, followed by suppressive therapy of metronidazole gel bid for 4-6 months
What is the treatment of BV in pregnancy?
- oral treatment is preferred
- metronidazole 500 mg bid for 7 days
- clindamycin 300 mg po bid for 7 days

What are the complications associated with a trich infection?
- low birth weight infants
- tubal infertility
What are the signs associated with a trich infection?
- large amounts of white or yawl frothy discharge (can also be green)
- redness of the vulva and the cervix
