surgical emergency cannot be excluded, causing acute abdomen
clinically severe disease
tubo-ovarian abscess
PID in pregancy (v.rare as foetus in way for ascending infection)
lack or response/intolerance to oral therapy

29
Q

when might laparoscopy/laparotomy be considered for PID?

if no response to therapy
clinically severe disease
presence of a tubo-ovarian abscess

an US-guided aspiration of pelvic fluid collections would be less invasive

possible SEs of metronidazole?

A

vomiting, this would be made worse if alcohol taken

31
Q

what is a patient with PID at risk of in the future?

A

ectopic pregnancy as pelvic scars and adhesions
infetility as tubal adhesions
chronic pelvic pain- may need counselling
Fitz Hugh Curtis syndrome- adhesions by liver

32
Q

what is fitz hugh curtis syndrome?

A

perihepatitis presenting with R upper quadrant pain- acute in onset and sharp, due to transabdominal spread of infection from PID e.g. chlamydia trachomatis.
The spread of disease from the pelvis to the liver may be due to circulation of fluid along the paracolic gutter- infracolic compartment of greater sac, it may be due to lymphatic drainage or it may be via the bloodstream.

33
Q

How can risk of PID be reduced in patients who have had it previously?

A

use of barrier contraception

34
Q

clinical presentation of primary genital herpes?

Q

How can risk of HSV transmission be reduced?

A

barrier contraception

37
Q

tment of primary genital herpes and severe disease?

A

aciclovir- only activated within virally-infected cells as molecule produced by virus necessary for drug activation, so therefore minimses damage to cells not infected by the virus
