2: Gynecologic Infections Flashcards
Why is penetration by sperm less likely to occur after ovulation?
Once ovulation occurs, progesterone secreted from the corpus luteum converts the cervical mucus into a thickened, tenacious substance, making penetration by sperm unlikely.
T/F There exist effective alternative treatments for BV.
False. Research is actively underway, but few studies currently demonstrate safety, effectiveness, and long-term outcomes of alternative treatments. Consider reliable sources only (no blogs and unsubstantiated websites).
When are amines produced?
Byproduct of anaerobic metabolism.
Among reproductive-age women in the United States, the prevalence of BV has been reported to be approximately _____%.
Among reproductive-age women in the United States, the prevalence of BV has been reported to be approximately 29%.
Many women develop VVC symptoms following treatment with what med? How is this sometimes handled?
Nitroimidazole. Providers often co-prescribe an antifungal, such as fluconazole.
An inflammation of the vagina that is NOT characterized by an increase in white blood cells.
Vaginosis
During what two phases of a woman’s life are vaginal secretions minimal and why?
- Before menarche
- After menopause
Low estrogen levels decrease secretions.
3 most common causes of abnormal vaginal discharge.
- Bacterial Vaginosis (BV)
- Vulvovaginal Candidiasis (VVC)
- Trichomoniasis
T/F There is clear evidence of how to screen and treat women with recurrent BV.
False. Although the majority of women with BV are asymptomatic, a significant number experience recurring and chronic symptoms. The scientific literature has not settled the controversy regarding whether and when to screen women with chronic recurrence and how to treat them.
How should recurrent BV be treated?
The CDC has considered the problem of recurrent BV and suggests retreating women with this condition with the original therapy, using metronidazole gel intravaginally weekly for 4 to 6 months, or monthly oral metronidazole with fluconazole. No studies have found a regimen effective enough to be recommended for treatment of recurrent BV.
In BV, what does miscroscopy show?
Clue cells (vaginal epithelial cells coated with bacteria that obscure cell borders) in the sample with normal saline is a characteristic sign because this phenomenon is specific to BV. A reduction in lactobacilli and typically very few white blood cells are noted.
When should you treat BV?
The CDC recommends treatment for symptomatic women.
Why do we want estradiol to increase the amount of cervical mucus and make it thin and watery?
To enable penetration of sperm immediately prior to ovulation.
When using clindamycin cream to treat BV what patient education should you include?
Clindamycin may weaken latex condoms or contraceptive diaphragms.
T/F The amount of vaginal discharge a woman experiences is not, in itself, an indication of infection.
True
What is BV associated with in pregnant women?
BV is associated with:
- chorioamnionitis
- premature rupture of fetal membranes
- preterm labor and birth
- postpartum endometritis
An increase in the amount of vaginal secretions is called _____.
An increase in the amount of vaginal secretions is called leukorrhea.
What is the most common symptom of BV?
Malodorous discharge.
An inflammation of the vagina characterized by an increased vaginal discharge containing numerous white blood cells.
Vaginitis
What promotes growth of opportunistic and pathogenic organisms in the vagina?
- Antibiotics
- Vaginal lubricants
- Hormonal contraceptives
- Douching
- Other behavioral and intrinsic factors
Name preventive measures for vaginal infections.
- General health promotion (rest, reduced stress, healthy diet low in sugar).
- Good personal hygiene (regular, gentle cleansing and drying of perineal area removes perspiration and smegma accumulations).
- Towels, sponges, douching equipment, sexual equipment, underwear, etc. should be cleaned after each use and never shared.
- Proper wiping (front to back–most critical thing to teach).
- Avoid sprays, powders, etc. that are perfumed or irritating.
- Avoid chemicals that irritate skin or alter vaginal pH.
- Avoid tight clothing in the crotch area (does not allow free flow of air or traps moisture).
- Discourage daily use of panty liners (trap moisture). Counsel women to change pads, liners, tampons frequently, never wear tampons to bed, and don’t use tampons when flow is scant.
- No douching except when recommended by clinician.
- Cotton crotches.
- Clip hair in vaginal area (no waxing, shaving, etc.).
What is the difference between vaginitis and vaginosis?
Vaginosis is not associated with an increase in white blood cells.
How should hair be managed in the vaginal area and why?
Recommend against vulvar shaving, waxing, and use of depilatories, as these practices strip the vulva—and, therefore, the vagina—of protective hair, expose the skin to bacteria, and may lead to severe inflammatory reactions. Excessive vulvar hair can be clipped with scissors rather than shaved or waxed.
What 2 things usually have pH of 4.5 or greater?
- BV
- Trichomoniasis
Can pap tests be used for diagnosis of BV?
No. Pap testing is both nonspecific and nonsensitive for diagnosing BV. Furthermore, vaginal cultures are not useful because BV is multibacterial in origin and cultures are nonspecific.
Who is most likely to need teaching about preventive measures for vaginal infections?
They are important for all infections, but particularly for women with recurrent vaginitis.
