questions 4 Flashcards
what is normal discharge + cause
are different sorts of discharge and recommendations
Normal
clear or white, thin, not purulent
physiology
cervix makes more mucous (vagina doesn’t have glands)
increased PV dx- leucorrhoea - shedding of superficial mucosal cells
Grey / smelly- BV

signs
risks in pregnancy
screening
how to test
what is it
bacterial infection
transmitted- Sexually transmitted or in pregnancy (not airborn / touching)
Signs
- usually asymptomatic. yellow dx, dysuria, pelvic pain, abnormal PV bleeding
risks
- miscarriage, preterm birth, ectopic birth, IUGR, vertical transmission
- Congenital conjunctivitis
screening
risk based- <25yrs
how to test
vulvo VAGINAL swab (self collected)
- first void urine
recommend partner gets treated too
recheck in 3mths
treatment-azithromycin

signs- flu like symptoms
risks
stillbirth, congenital abnormalities
vertical transmission
breastmilk
screening
risk based
mgmt
prevention- good hygeine
no treatment
TRANSFER
No treatment in pregnancy- give antivirals to neonate to reduce chane of serious problem
Syphilis
what is it + type of transmission
risks in pregnancy
screening
mgmt
bacterial infection - sexually transmitted (not via normal contact) + through placenta
risks
