1
Q

What is the most important mechanism of pathogenesis for Gonorrhea? Name some of sx of gonorrhea

A

Pilli! allows for adherence to mucosa so it can evade phagocytosis
When you stick your pilli in bad places, you’re going to need a pil(i) to make you feel better
Sx: Abdominal pain and discharge

Q

Describe the evolution of the vaginal epithelium? i.e. how it begins, how it ends, where it comes from etc…

The lower 1/3 of the vaginal epithelium, which is squamous epithelium, is derived from the urogenital sinus. The upper 2/3 of the vaginal epithelium is derived from the Mullerian ducts. The squamous cells grow upward and take over the upper 2/3 of the vaginal epithelium

Q

High risk HPV produces E6 and E7. What are functions of E6 and E7?

Q

Explain anovulatory cycle. Why does the woman bleed? Length of cycle.

A

There is an estrogen drive proliferative phase without a subsequent progesterone phase. The bleeding occurs due to the inability of estrogen to maintain the corpus luteum, as opposed to a regular cycle when bleeding takes place due to progesterone withdrawal.

Length of cycles vary…
