Gynaecology Flashcards
Causes of PID
Chlamydia
Gonorrhoea
Mycoplasma genitalium
Anaerobes
Equivalent of PID in men
epididymorchitis
Mirena coil and PID
is protective
thickens mucus so bugs can’t climb up
High dose progesterone
thickens endometrium
Low dose progesterone
thins endometrium
Early pregnancy hCG
doubles every 28 hours (66%)
where else can you get chlamydia?
any columnar cells
eyes, gut, cervix, throat, urethra
NAAT sensitivity
80-100%
NAAT specificity
93-100%
How many with chlamydia are asymptomatic?
70%
Gonorrhoea treatment
ceftriaxone 2g Once
Anaerobes treatment
Metronidazole
14 days
400mg BD
Fitz hugh curtis
liver adhesions
If you only have 1 tube:
fertility down by 15%
If you only have 1 ovary
fertility down by 25%
RF for endometrial cancer
unapposed oestrogen PCOS Obesity Late menopause Ovarian thecal cell tumour family history of breast family history of colon (NHPCC)
How long is a cervix?
4-5cm
how thick should the endometrium ideally be?
<4mm
Cervical cancer stagin
- confined to cervix
- beyond cervix but not to pelvic wall or lowe 1/3 of vagina
- to pelvic wall or lowe 1/3 of vagina
- Invades bladder, rectum or METS
during puberty and pregnancy
the SCJ migrates down the os to the surface of the cervix. (ectopy)
The site where the columnar is undergoing metaplasia is called the:
transformation zone
Transformation zone
the area that cells under go metaplasia
SCJ
can move
migrates back up after puberty
Ectropian
can cause a lot of mucus
post coital bleeding
OCP can cause it
Metaplasia vs. dysplasia
metaplasia is normal
dysplasia is pre cancerous
HPV infects
squamous epithelium
Most dangerous type of HPV
16- 50% of cervical cancer
How many sexually active will get HPV?
70%
CIN 1
mild dysplasia (basal 1/3)
CIN 2
Moderate dysplasia (basal 2/3)
How many CIN 2 will regress in 2 years
50%
CIN 3
Severe dysplasia
Carinoma in situ (cervical)
CIN 3
Prognosis of cin3
18% cancer in 10 years
36% cancer in 20 years
Time between HPV infection and cervical cancer is
10-20 years
Recurrence of CIN?
20%
Rf for CIN
Young sex Multiple partners immunosuppressant drugs/disease HIV smoking
Acetic acid in smears
turns areas of dyslasia white
the greater the intensity of the white, the greater the level of dyskaryosis
Iodine solution in smears
Iodine is taken up by glycogen
normal squamous epithelium will appear very dark brown
-dysplastic cells don’t take it up and appreak yellow/orange
(sensitive, not specific)
silver nitrate
after biopsy
encourages haemostasis and is bacteriostatic
CIN 1 treatment
usually nothing unless persits for years
CIN 2/3 treatment
LLETZ
LLETZ complications
may require a c-section in furture
increased PPROM
increase pre-terms
Cervical cancer RF
SMOKING number of partners early first sex lots of sex HPV
Cervical cancer screening
25-65
every three years till 50 then every 5 years
borderline changes in endocervical cells
refer for colposcopy
borderline changes in squamous cells
repeat in 6 months
compare bast results
refer
need 3 in a row of normal ones before going back to normal scrrening
What type of cancer is cervical cancer?
80% Squamous cell
rest adenocarcinoma
symptoms of cervical cancer
post-coital bleeding
other bleeding
blood stained discharge
abnormal bleeding in pregnancy
staging of cervical cancer involves:
CXR
rectal exam
intravenous urogram
biopsy
cervical cancer staging survival
1-79%
2-47%
3-22%
4-7%
Cervical cancer 1b and up
may need a wider margin >5mm
Total hysterectomy
Radiotherapy (if can’t have surgery)
Most common type of endometrial cancer
adenocarcinoma
RF for endometrial cancer
high oestrogen no children late menopause PCOS obesity unapposed oestrogen diabetes family history of breast or colon cancer
Protective for endometrial cancer
COCP and pregnancy
endometrial cancer staging
- in body of uterus
- body of uterus + cervix
- outside uterus (in pelvis)
- outside pelvis
stage 1 endometrial cancer
- in body of uterus
a. endometrium
b. upper 1/2 myometrium
c. lower 1/2 myometrium
to shrink endometrial tumour:
medroxyprogesterone acetate
endometrial cancer survival overall
75% 5 years
recurrence of endometrial cancer
at vaginal vault!
how does endometriosis get to the lung?!
lymph of blood spread
frozen pelvis
so many adhesions from endometriosis
what is endometriosis?
you got this…
Treatment of endometriosis
COCP
Progesterones
Intrauterine systems
GnRH analogues
Side effects of GnRH analogues
Menopause-like side effects of GnRH analogues include hot flushes, vaginal dryness and low libido.
HRT may be recommended in addition to GnRH analogues to prevent these side effects.
