Q

A few things about biopsy:

locations?

anesthetic?

type?

post-biopsy care?

A
  • biopsy in a few locations
  • topical anesthetic
  • use a punch biopsy or scissor biopsy (cut off a little flap)
  • stop bleeding with presure + (a few agents I doubt we need to know) - rarely need suture

condition?

A

atrophic vulvovaginitis

-Very dry, withered. Thin, no wrinkles, no hair, Sore, uretha gets red.

Fix w estrogen

Wth time and estrogen, redness will go away tissues will be more moist and supple.

Flattening and scarring won’t go awa. Slightly larger clitoris due to androgen imbalance (too much androgen).

Q

HSV.

usually spread from a symptomatic or asx partner?

what is the recurrence rate for HSV I? HSV II?

Are women typically aware of their infection?

Primary HSV v recurrent HSV - prevalance of each?

A
  • Usually spread from an asymptomatic partner
  • Women are asymptomatic carriers of HSV, usually unaware of their infection
  • Recurrence rate for HSV I= 45%; HSV II= 89%
  • Prevalence: she says that ‘primary HSV is uncommon’ & women often present with recurrent HSV with no primary HSV history

What are the 4 types of common anatomical variants?

(this is an objective)

A
  1. Sebaceous gland hyperplasia (numerous, small 1-2 mm yellowish papules along the inner aspects of the labia minora. These are harmless but slightly oversized, normal, ectopic sebaceous glands.)
  2. Vulvar papillomatosis (look like warts, but they are soft rather than hard)
  3. Hymen types (crescentic v. microperforated v. imperforate)
  4. Labial hypertrophy (defined as width greater than 4cm). Reduction surgery if required.

Q

Genital HSV infection info:

Viral shedding pattern?

Do antiviral drugs stop all shedding?

A new primary genital infection in a young woman is more likely to be HSV 1 or HSV 2?

A

-HSV viral shedding occurs 1 day in 5 throughout life

-Antiviral drugs do not stop all shedding

  • HSV-1 is increasing in all age groups
  • New primary genital infections in young women are more likely HSV1 than HSV2
  • HSV-1 does not protect from HSV-2 (duh)
