This infection occurs as single or multiple small clear vesicles that may be very PAINFUL
The vesicles may blend to form tender, ulcerated lesions
This infection never truly goes away
It can cause loss of pregnancy and preterm delivery
If the mother has primary lesions then the infant MUST be delivered cesarean and there is a 33-50% chance it will be passes on to the baby, but the baby can be delivered vaginally if the mom is put on an antiobiotic 6 weeks before pregnancy

36
4 groups at high risk for HIV/AIDS
History of IV drug use (blood transfusion between 1978-85) Born/live in areas with high rate of infection Diagnosed with another STD History of multiple sex partners/prostitutes
37
A protozoan that is sexually transmitted that appears to have caused a vaginal pH greater than 4.5 Has yellow - green frothy discharge, vulvovaginal burning, pruitis, dysuria (pain/difficult urination), urgency, frequency, dyspareunia (pain/difficult intercourse), post coital spotting, lower ab pain, or could even be asymptomatic
Trichomonas vaginalis
38
Commonly "a trichy chick has a strawberry cervix" means..
With trichomoas vaginalis there is usually petechiae on the cervix
39
Treatment for trichomonas vaginalis
Metronidazole (Flagyl) Sex partners should be treated as well There is no treatment allowed during the first trimester because there is an antabuse effect
40
This vaginal infection is not sexually transmitted and usually follows antibiotics, the infection thrives on heat, moisture, and sugar causing yeast to grow This includes candidiasis, moniliasis, thrush, and yeast
Candida (monilia) vaginitis
41
Risk factors for Candida (monilia) vaginitis [candidiasis, moniliasis, thrush, yeast]

Candidiasis (the -azoles)
44
This is not considered an STI Has a fishy odor, gray white milky discharge, and itching The vaginal pH will be greater than 4.5 It can cause pelvic and intrauterine infections This will have clue cells under the microscope
Bacterial Vaginosis
45
What is the treatment for Bacterial Vaginosis (BV)
Pregnant women will get Clindamycin, | not pregnant women can use Flagyl
46
This is common, approx 23% of pregnant will get it. There is a prenatal screening routine during the 3rd trimester and if found it will be treated with antibiotics during labor. But it can cause maternal infection leading to premature labor (PTL) or a premature rupture of membranes (PROM) leading to fetal infection or death
Group Strep B
47
What is a TORCH infection
``` Toxoplasmosis (fungal infection) Other infection such as hepatitis Rubella Cytomegalovirus Herpes simplex ```

Toxoplasmosis (fungal infection)
49
Causes 74% congenital anomalies if pt has in first 4 months of pregnancy, but the vaccine is a live attenuated virus so it cannot be given during pregnancy

50
This is severe and can be fatal if developed during pregnancy. The first trimester is associated with congenital anomalies such as limb or skin scarring, Horners syndrome which is paralysis of facial nerves, and also low birth weight LBW
Varicella (chicken pox) | --Varicella zoster immunoglobulin (VZIG) is administered to protect fetus
51
There is no treatment for this, if developed when pregnant the baby can develop CNS abnormalities

56
Risks/cons of female condoms
Allergy of polyurethane Noisy during sex Expensive for frequent use
57
Risks/cons of a diaphragm with spermicide
Does not protect against STIs: spermicide actually increases risk of STI transmission Must be inserted 6-8 hours before sex (could be a benefit) Requires fitting by healthcare provider Allergy to latex, polyurethane, rubber, or spermicide May have symptoms of toxic shock May become dislodged in female
58
Benefits of diaphragm with spermicide
Does not use hormones | May protect a little against cervical cancers
59
Benefits of a cervical cap with spermicide
Provides continuous protection for 48 hours | No use of hormones
60
Risks/cons of a cervical cap spermicide
``` No STI protection Wait 30 minutes after insertion to have sex Wait 6 hours to remove it after sex Irritation may occur Allergic reactions Have an abnormal pap test Risk of toxic shock syndrome Requires fitting Odor may occur if left in too long ```
61
Benefits of a sponge with spermicide
Offers immediate and continuous protection for 24 hours
62
Risk/cons of a sponge with spermicide

Benefits of oral contraceptives
Pill form so its easy to use against pregnancy Estrogen forms: protect against ovarian and endometrial cancers Progestin only forms: no estrogen side effects, may be used by lactating women, and women with a history of thrombophlebitis
64
Risks/cons of oral contraceptives
No STI protection, taken daily Combination forms: dizziness, nausea, mood changes, high blood pressure, blood clots, heart attacks, stroke Progestin only forms: must be taken at the same time every day, less effective than combination and may cause irregular bleeding, weight gain, increased incidence of ectopic pregnancy, should be screened for ovarian cysts, previous ectopic pregnancy, and hyperlipidemia

80
When the inner lining of the uterus (endometrium) is expelled from the body
Menstruation
81
