Hi - Gynae Flashcards
name the key components of the gynae tract
vulva
vagina
cervix
uterus
fallopian tubes
ovaries
what are presenting Sx of female genital tract disease
discharge
PV bleeding
pain - dyspareunia
dysuria
itching
name 3 congenital gynae abnormalities
duplication
agenesis / atresia
what is inflammation of the following called:
- vulvla
- vagina
- cervix
- endometrium
- fallopian tube
- ovary
vulvitis
vaginitis
cervicitis
endometritis
salpingitis
oophoritis
what gynae infections cause discomfort but not serious complications
candida
tichomonas vaginalis
gardenerella
what increases development of gynae candida infection
DM
OCP
pregnancy
which gynae infections have serious complications
chlamydia
gonorrhoea
mycoplasma
HPV
what gynae complication do chlamydia and gonorrhoea cause
infertility
what obstetric complication occurs with mycoplasma
spontaneous abortion and chorioamnionitis
what is the risk of contracting HPV
cancer
what is infection of upper female genital tract called
pelvic inflammatory disease
3 organisms causing PID which spread from lower genital tract via musocal surfaces
gonorrhoea
chlamydia
enteric bacteria
how do strep / staph etc cause PID
secondary to abortion
starts from uterus and spreads by BVs and lymphatics
complications of PID
peritonitis
bacteraemia
obstruction due to adhesions
infertility
how does salpingitis occur
direct ascent from vagina
complications of salpingitis
infertility & ectopic are the 2 key/worst ones !!
plical fusion, adhesions to ovary, absecess, peritonitis, hydrosalpinx
where do 95% of ectopics occur
fallopian tubes
3 diseases of the cervix
inflammation
polyps
dysplasia / carcinoma
how common is cervical cancer worldwide
2nd most common
mean age of cervical cancer
45-50 years old
what is the premalignant phase of cervical ca
cervical intraepithelial neoplasia
how can cervical cancer be prevented
possible vaccination
screening to detect premalignant stage
what % of cervical Ca has HPV
95%
RFs for cervical ca
HPV
many sexual partners
sexually active early in life
smoking
immunosuppressive disorders
what types of HPV are low risk
6 and 11
what does low risk HPV cause
genital and oral warts
low grade cervical dysplasia
what types of HPV are high risk
16 and 18
what does high risk HPV cause
low and high grade cervical dysplasia
cervical cancer
vulva / vagina / penis / anus cancer
describe the disease progression of cervical cancer from HPV
- normal epithelium
- HPV infection - causes some abnormal cells
- get low grade dysplasia in a single layer of epithelium
- mild/mod dysplasia in multiple layers of epithelium
- high grade dysplasia - covers the entire epithelium
- carcinoma - invades through basement membrane
name the 3 stages of dysplasia before it becomes cervical carcinoma
cervical intra epithelial neoplasia 1 (few dysplastic cells)
CIN 2 (multiple layers of dysplasia)
CIN 3 (whole epithelium is dysplastic)
what feature differentiates cervical intraepithelial neoplasia from carcinoma
invasion through BM
2 principle types of cervical carcinoma
squamous cell
adenocarcinoma
what % of invasive cervical cancer is adenocarcinoma
20%
how is prognosis determined for cervical cancer
FIGO staging 1 to 4
grade and type of tumour
lymphovascular space invasion
what % of survival is FIGO stage 1 vs 4
1 = 90%
4 = 10%
2 types of HPV infection
latent or active
in what phase of HPV infection is cancer more likley to occur
active, persistant infection
- in latent the virus is not producing virions so is largely undetectable
what ages are invited to the cervical screening programme
25 to 64
how frequently are smear tests done
25 - 49 = 3 yearly
50 - 64 = 5 yearly
