• Usually more acute sxs– pain, discharge
Obstetric risks involved w/ PID?
Obstetric: Incr risk of premature delivery
- Premature rupture of membranes

Gonorrhea: blindness, sepsis
Chlamydia: eye infection, respiratory, pneumonia
PID - Diagnosis?
Physical Exam:
- Cervical motion tenderness
- Mucopurulent discharge;
- Diffuse lower abdominal tenderness/ tenderness on pelvic exam
(cervical culture/ urine for positive for gonorrhea/ chlamydia)
Laproscopy:
– Edematous tubes/ adnexa – purulent discharge
Perihepatic adhesions:
- Fitz Hugh Curtis syndrome = diagnostic of prior PID
– But most patients will NOT have symptoms –
When does the CDC recommend that women are screened for PID?
- Yearly screening of all females < 25 years
- or >25 if new partner or multiple partners
(Cervical culture or urine test)

May be associated w/:
- Preterm labor
- Rupture of membranes
- Prolonged labor
What Obstetrics-related infection has an increased risk with cesarean?
Endometritis
infection of endometrium/myometrium
_____ slows motility of smooth muscle of urinary tract, potentially leading to UTI/Pyelonephritis.
Progesterone

Which of HSV’s can cause genital disease? Recurrent?
Both can cause genital disease & be recurrent
Describe “Primary” vs. “Non-primary” HSV infection.
