16
Q

T/F gonorrhea and chlamydia often cause vaginitis

A

F –> squamous epithelium is resistant

17
Q

____ produces peroxides in the vagina contributing to infection resistance.

A

lactobacilli

18
Q

PID

A

upper tract infection involving endometrium, fallopian tubes, or ovary

19
Q

____ and ____ are the only true causes of PID

A

gonorrhea and chlamydia

20
Q

T/F upper tract infections need more broad spectrum Abs than lower tract infections.

21
Q

adnexa

A

that area of the ovarian tube adjacent to the uterus

22
Q

complications of acute PID

A

infertility from scarring/hydrosalpinx, ectopic pregnancy, chronic pelvic pain, tubo-ovarian abscess/peritonitis

23
Q

Interstitial salpingitis

A

consequence of patent fimbrial end with scarring within the tube

24
Q

Tubo-ovarian abscess

A

if fallopian tube is inflamed and infection spreads to ovary, pus simply fills the interstitial space

25
Pyosalpinx
occlusion of the fimbriated end prevents release of tubal content --> exudate is absorbed and forms a hydrosalpinx after the acute phase
26
Pathologic definition of pid
chronic salpingitis with involvement of surrounding structures including ovary and parametrium
27
IUD and PID relationship
no increased rate of PID or ectopic pregancy
28
Historically ____ infection was associated with IUDs, probably due to coinfection with asymptomatic gonorrhea or chlamydia.
actinomyces israelii
29
Tubal abortion of ectopic pregnancy
expelled from fimbrial end of tube
30
Tubal hemorrhage due to ectopic pregnancy
decidual change is focal and poorly developed -->cannot buffer trophoblastic invasion of vessels
31
Tubal rupture in ectopic pregnancy
50% of tubal pregnancies --> acute onset, intraabdominal hemorrhage, acute abdominal pain
32
T/F new IUDS are not associated with increased risk of PID and ectopic pregnancy
T
33
T/F ectopic pregnancy is a potential sequelae of pid due to post-inflammatory damage to fallopian tubes
