35
management of primary dysmenorrhoea?
NSAIDS e.g. mefanamic acid and ibuprogen inhibit prostaglandin production 2nd line: COCP
36
State some causes of secondary dysmenhorroea? occurs many years after menarche and is a result of underlying pathology
1. endometriosis 2. adenomyosis 3. pelvic inflammatory disease 4. intraurertine devices 5. fibroids
37
what should be done for all patiens with secondary dysmenorrhoea?
refer to gynae for investigation
38
+ve pregnancy test + mild suprapubic gain management:
refer urgently to EPAU need to rule out ectopic pregnancy.
39
COCP protective against
Increases the risk of cancers we screen - breast - cervical protective against those we don't - endometrial - ovarian
40
Lynch syndrome increases risk of what chancers
LYNCH syndrome is the CEO of cancers C- colon E- endometrial O-ovarian
41
which contraceptive associated with delayed return to fertility?
Depo-provera is recommended to be stopped after 50 years. increased risk of osteoporosis. so continuing it in a post-menopausal woman would increase her risk of a fragility fracture
42
how does IUS work?
thickening cervical mucous
43
contraindication for depo-provera?
breast cancer
44
which is associated with development of ovarian cancer? - early menarch - early menopause - COCP - multiple pregnancy - low BMI
EARLY MENARCHE risk is greater is ovulation is no suppressed.
45
investigation for ovarian cancer
1. CA125 | 2. USS
46
can oral anticoagulants be continued in pregnancy?
NO contraindicated so women on NOACs should be switched to LMWH why? - placental haemorrhage, fetal prematurity and fetal loss
47
how can galactocele's be clinically differentiated from breast abscesses?
Galactocele - painless - non-tender - no localised erythema - afebrile
48
next appropriate step in investigation of galactocele?
no further investigation needed can be differentiated from breast abscess through clinical HX + OE findings
49
in gestational diabetes, if blood lgucose targets are not met with diet/ metformin what is the next step in management?
commence insulin
50
inital step in induction of labour?
Membrane sweep separating chorionic membrane from decidua to trigger labour. if this fails then vaginal prostaglandins are recommended. options 1. membrane sweep 2. vaginal prostaglandin e2 3. maternal oxytocin infusion 4. amniotomy 'breaking of waters' 5. cervical ripening balloon
51
What bishop score would indicate spontaneous labour is likely?
score above 8
52
risk factor of prostaglandins in labour
uterine hyperstimulation CTG - baby having decelerations stop p.glandins and start tocolysis: terbutalnine
53
example of tocolytic used in preterm labour
nifedipine relax uterus half contractions and labour
54
high ALP indicates
- either bone problem | - or cholestatic picture
55
markers of inflammation in liver
ALT AST liver enzymes
56
which is bad, early or late decelerations on CTG? MX
- LATE decelerations - require fetal blood sampling - to assess for fetal hypoxia + acidosis
57
management of ovarian caners:
primary - if stage 2-4 --> surgical excision of tumour - then chemotherapy

59
initial investigations of ammenohorea?
1. bHCG 2. FBC, U&Es, coeliac, TFTs 3. gonadotrophins - low levels --> hypothalamic cause - raised --> ovarian (premature ovarian failure) 4. prolactin 5. androgen - raised --> PCOS 5. oestrogen
60
management of preterm labour: early stage
