Q

17 y/O cyclic pelvic pain and deep dysparenuria has a boyfriend but no wish to concieve at present takes paracetamol and diclofenac with minimal effect diagnostic laposcopy demonstrates small amounts of endometriosis on the uterosacral ligaments

A

medical simple analgesics have helped so as ther endo is mild med option should be tried with COCP which can provide contraception too and surgical optiosn should be reserved for cases where med managment has failed or fertility is desired and she be carefully ocnsidered in someone so young

Q

Rotterdam criteria in PCOS

A

Summarises the many features of PCOS
S - Strings of pearls
H - hyperandrogenism(too much teststosterone) acne hirtis
O - oligomenhorrea - period at intervals > 35 days
P - prolactin normal

prolactin t4 and cortisol need to be normal and the first two are deffo needed for a diagnosis but this method is flawed as it does not tkaae into consideration the insulin resistance present in many people

Q

management in pcos

A

is dependent on the clinical presentation

  1. weight loss
  2. acne - benzoyl peroxide and or Abx
  3. oligomenhorrea - check endo thickness and induce withdrawal bleed with progrestrogen or COC
  4. Infertility- weight loss, metformin, ovulation with clomifen IVF with gonadotrophins

25
What does clomifen do ?
blocks oestrogen recpetors at hypothalmus and pitutary to prevent negative feedback and lead to inc FSH stimulation folicular development
26
SE of clomifen
ovarian hyperstimulation where the ovary increases in sizze and multiple follicles release vegf causing ascities and if severe systemic reaction with shock
27
primary amenhorrea and secondary amenhorrea definition
primary is failure of menstruation by 16 years with otherwise normal sextual characteristics Secondary is absent periods for 6 motnhs in a women who had previously regular periods or 12 months in women with irregular periods
28
Causes of amenhorrea
PREGNANCYYYYY!!!!!!!!!!!!!! Hypothalamic - GnRH defisincey Pituitary tumour- hyperprolactinoma inhibiting ovulation c pituitary necrosis in (sheehan syndrome) Ovarian- PCOS premature ovarian insufficentcy Outflow probs - imperforate hymen , cervical stenosis absent uterus (rokitansky !!!)
29
Investigations for amenhorrea
1. pregnancy test 2. thyroid function - hyper hypo inhibits ovulation 3. LH/FSH 0 raised =ovarian insifficentcy reduced = hypothalamic/pit problem increased = FSH/LH Testosterone - exclude androgen secreting tumour USS if abnormal gential tract suspected
30
treament of gonadotrophin insufficientcy
replace them if fertility desired if not COCP
31
pcos treatmenet
wl ,metformin /ovulation induction if fertility desired | wl cocp if fertility not desired
32
ovarian insifficentcy treatment
no treatment but COCP and HRT may improve symptoms eff donantion if fertiltiy desired
33
Gential treat abnormality treatment
outflow obstruction then its urgical | Tokitansky -no treatment surrogagcy
34
Chylamidia signs
dysuria and discharge intementsrual and post coital bleeding ascending infection acute salpingitis or PID On hisotoly there will be elementsry bodies which become reticulocyte bodies which produces discharge
35
THE SWABS to use for this in female
the bacteria enters the endocervix in women therefore that needs to be endocervical swab
36
treatment of chylamidia
antibiotics oral doxycycline 100mg BD for 7 days erythromycin in pregnancy gonoccocu co infection then azihtromycin and ceftriazone SEX in trichomonas ?
37
Signs and symptoms of PID
typically bilateral deep dysparenuria vaginal discharge and abnormal vaginal bleeding
38
Cuae of PID
mixture of organism as the travel up the genital tract
39
Acute PID/SALPINGITIS symptoms
low abdo tenderness, fever, cervisitits cervical motion tenderness and adenexal tenderness
40
investigation in acute PID / salpingitis
FBC CRP triple swabs pelvic USS or laparoscopy if uncertain
41
Treatment of PId/ SALPINGITIS
ceftriaxone then oral doxycycline metronidazole for 14 days if fever unwell pertonism admit for IV therapy
42
Subfertility How long do you need to try for at least
a failure to concieve after 12 months regular unprotected intercourse primary female partner never conceived sexondary female partner has conceived 2 years
43
commonest cause of subferitlity
annovulation can be due to hypothalamopituitary acis
44
hypthalamic causes of annovulation
stress anorexia
45
anti pit causes of annovulation
prolactinoma
46
ovarian causes of annovulation
PCOS or premature ovarian insifficentcy (D21 confirms ovulation)
47
How do you address tubal patency
with a hysterosapingogram where you fill and spill or a lapaoscopy and dye
48
male factor subfertiltiy and investigation
Azospermia- absent spermatozoa few spemaozoa - oligospermia excess or abnormal sperm - teratozoospermia a significant proportion of immotile sperm asthenozoospermia semen analysis count>15million motility >40% and forms of sperm >4
49
Treatment for subferitlity
conservative - weightloss smoking cessation refuce caffeine and alcohol intake and intercorurse 2-3 times a week timing cycyle not recommended as it creates stress medical treatment - annovulation - comifene gonadoptrophines GNRH with or without asisted reporduction
50
treamtent presmature ovarian insufficiency subferiltiy
egg donation and iVF
51
Tubal damage IVF
tubal surgery or IVF
52
MALE FACTOR TREATMENT
asisted reporduction
53
The three asisted repro techniques
1. intrauterine insemination - good for azospermia can select the fast sperm 2. in vitrofertilidation 3. intracytoplasmic sperm injections - single sperm into a single egg good for oligospermia
54
Difference betwen miscarrigae early preganacy loss and premature preterm labour
miscarrigae - >24 weeks early preganancy loss <12 weeeks early premetm labour is give steorids and its after 24 weeks
55
the imporance of uss in a miscarrigae
confirms location of the pregnancy femosntratess fetal heart rate on uss an is associated with a sucessful pregnancy and visualise the adenexa - for ectopics too
56
investigations in miscarrigae
FBC blood group and antibosy and rhesus status
57
three types of managment for a miscarriage
FIRST CONFIRM DIAGNOSIS WITH USS 1. expectant wait and see - first line and resolution takes wks Explore other options if at increased risk of bleeding adverse exp of pregnancy or women prefers : 2. medical - vaginal prostaglafin misoprostolol 3. surgical - evaculation of retained products of conception 4. give anti d if rhesus negative
58
how to investigate a pregnancy of unknown origin on transvaginal uss
1. will have done a TVUSS first 2. HCG measure it 1500> = increased = intrauterine preganancy likely but its probs so early cant be seen on USS repeat in 7-14 dys Suboptimal increase = ectopic pregnancy - clincial review within 24 hrs - look for this it should double every 2 days in early prehgnancy !!! decreased = falling preganancy do a pregnancy test in two weeks
59
RF FOR ECTOPIC | and the three symptoms
``` P = Previous ectopic I = intrauterine contraceptive device P = prelvic inflammatory disease P = pelvic or tubal surgery A = assisted repro ``` bleeding amenhorrea and pain
60
pelvic exam of a ectopic
cervical motion tenderness | uterine size does it match gestation
61
how does molar prgegnancy present
vaginal bleeding in fisrt trimester with all symptoms of prhganncy exaggerated high HCG and hyperemesis gravidum
