STDs/PID/PATH Flashcards
What type of test would you commonly use to test for Trichomonas?
An NAAT!
At what age is chlamydia most common?
15-24
At what age is gonorrhea most common?
Young adults, 20-24
What type of test would you usually use to test for syphilis?
A serologic test (RPR and specific treponemal antibodies)
Does chlamydia have a high chance of being transmitted when one person is infected? What about Hep c?
Chlamydia has a very high chance of being transmitted. Chance of transmission of Hep C is low.
What are the most common and recommended platforms for detecting common STIs?
Nucleic Acid Amplification Tests (NAATs)
What sort of growth media do you need to grow Chlamydia?
What about gonorrhoeae?
Chlamydia - no idea
Gonorrhoeae - a complex thayer-martin or chocolate agar media, humid atmosphere supplemented with CO2.
What is the minimal criteria for pelvic inflammatory disease?
Lower abdominal pain
For which STI is the following statement true:
Women have 50% acquisition after single exposure to infected men. Men have 20% acquisition after single exposure to infected women. Risk increases with number of encounters.
Gonorrhea
What STIs can you detect with NAATs?
Chlamydia, Gonorrhea, Herpes, Trichomonas, HPV
What do you commonly use serologic (antibody/anigen) tests for?
Syphilis (RPR and specific treponemal antibodies), Hep B (surface antigen), Hep C (antibody)
What type of bacteria is Gonorrhea?
Gram-negative diplococci
Is gonorrhea always symptomatic in men? What about in women?
Gonorrhea in men is always symptomatic. In women, it can be asymptomatic. (Or they might notice increased vaginal discharge).
What STI causes neonatal conjunctivitis in 30-50% of exposed babies?
Chlamydia
Can animals get Gonorrhea?
No - it is a strictly human disease.
Is Gonorrhea more common in women or in men?
Women - women have 50% acquisition after single exposure to infected men. Men have 20% acquisition after single exposure to infected women. Risk increases with number of encounters.
True or false: Gonorrhea dies rapidly if allowed to dry.
True
Oophoritis
Infection of the ovary
Is gonorrhea intracellular?
No
Is chlamydia intracellular?
Yes
Salpingitis
Infection of the fallopian tube
Is gonorrhea or chlamydia more likly to cause host-immune responses? Which causes more subtle, less painful damage? Are women with chlamydia or gonorrhea going to be sick more quickly?
Chlamydia.
What is the most common STD in the US?
Chlamydia
What is the most predominant vaginal organism? How does this contribute to vaginal pH?
Lactobacilli - this forms peroxide leading to acidic pH
What is vaginal pH?
Acidic
Infection of the ovary
Oophoritis
What is cervical mucus made of?
Complex glycoprotein with variable water content
Endometritis
Infection of the endometrium
Why do you need a more broad spectrum antibiotic approach when treating an upper tract gonorrhea and chlamydia infection (as opposed to a lower tract infection)?
You develop secondary infection in which organisms that normally colonize the vagina invade!
Adnexa
Segment of the tube adjacent to the uterus
Cervical motion tenderness
When the cervix is very tender during a pelvic exam; this is generally a finding in PID
When the cervix is very tender during a pelvic exam it is called
Cervical motion tenderness
Minimal criteria for diagnosis of PID
- Lower abdominal pain
- Adnexal tenderness
- Cervical motion tenderness
(but people who have these things do not necessarily have pelvic inflammatory disease)
What are three possible courses in progression from acute to chronic salpingitis?
- Fimbrial end remains patent
- Spread to ovary
- Occlusion of the fimbriated end
