what are the symptoms of pelvic organ prolapse
recurrent UTI
feeling of pelvic fullness
FUNI urinary signs
treatment of pelvic organ prolapse 4
- pelvic floor exercises
- weight loss if obese
- ring pessary to hold vaginal walls in place
- surgery
cystocele: anterior colporrhaphy
uterine: hysterectomy
rectocele posterior colporrhaphy
What are the three classifications of pelvic organ prolapse according to the affected compartment?
Anterior compartment: cystocele (bladder prolapse into anterior vaginal wall)
Middle compartment: uterine prolapse (Cervix prolapses into vagina)
Posterior compartment: rectocele (bowels prolapse into vagina)
What are fistulas? What are the 2 genital tract fistulas?
an abnormal connections between two epithelial surfaces
vaginal fistula (vagina opens into bladder/ rectum)
perianal fistula (anus connects to skin)
What are the concerns with genital tract fistulas?
- bacterial overgrowth and can lead to infections
What is the ix for anal tract fistulas?
- DRE
- MRI to identify the course of the fistula
What is the mx for anal tract fistulas? 5
Management of anal fistula generally involves a combination of surgical, medical, and supportive therapies:
1. analgesia + wound care
2. delineate (define borders of fissure better) using barium + CT
3. control crohns (linked to anal fissures and prevents healing until well controlled)
4. abx for infection
5. fistulotomy, using Goosalls rule

resistance to testosterone
causes children with male genotypes (XY) to have a female phenotype
What are the features of androgen insensitivity syndrome 4
female with:
‘primary amenorrhoea’
little or no axillary and pubic hair
undescended testes causing groin swellings
breast development may occur as a result of the conversion of testosterone to oestradiol
How is Androgen insensitivity syndrome diagnosed 1
- buccal smear or chromosomal analysis to reveal 46XY genotype
How is androgen insensitivity managed? 3
-> bilateral orchidectomy to reduce testicular cancer risk due to undescended testes
-> oestrogen therapy
-> raised child as female

diagnosed when a woman has not had a period for 12 months
40-50 years
7 years, some more, some less, some symptoms can start years after menopause
What are the features of menopause 5
- change in length of menstrual cycles
- vasomotor sx: hot flushes and night sweats
- vaginal dryness and atrophy
- anxiety and depression
- urinary frequency
How is menopause managed?
- lifestyle mods: good sleep hygiene, exercise, relaxing to reduce stress
- oral/ transdermal combined HRT (cannot give oestrogen on its own as it can increase risk of endometrial cancer if the woman has a uterus so daily progesterone pill)
- symptom management eg vaginal lubricant for vaginal dryness
- fluoxetine for vasomotor symptoms and depression
- vaginal oestrogen if suffering from urogenital atrophy (can be prescribed alongside HRT)
What does oestrogen HRT increase your risk of? 4
- venous thromboembolism

What are the features of prolactinomas
Females:
-amenorrhoea: absence of menstrual period
-oligomenorrhoea: irregular
Males
-erectile dysfunction
-reduced facial hair
-galactorrhea
Both
-low libido
-infertility
-N/V/ headaches due to increase ICP
What is the pathophys of prolactinoma **
- prolactin hypersecretion inhibits gonadotrophin-releasing hormones
- therefore this is secondary hypogonadism (hypogonadism is a problem in the pituitary or hypothalamus) because it inhibits gonadotrophin-releasing hormones
- hypogonadism= gonad sex glands produce little or no sex hormones
How is prolactinoma investigated
- serum prolactin
- MRI brain diagnoses prolactinoma
What is the management for prolactinoma
medical approach is more efficient than surgical, unlike other pituitary adenomas
-> 1st line: dopamine agonists eg oral cabergoline/ bromocriptine (dopamine inhibits prolactin release and will cause shrinkage of the prolactinoma)
-> transphenoidal resection surgery of pituitary gland (for adenoma)
-> hormone replacement therapy to deal with hypogonadism eg oestrogen where fertility and galactorrhea are not an issue
What is a molar pregnancy
an abnormal form of pregnancy where a non-viable fertilised egg implants in the uterus- very similar to a tumour so it needs to be removed

- germ cell tumours (benign epithelial cell tumour, benign sex cord stromal tumour)- MC in women under 30
What are complications of ovarian cysts 3
cyst rupture (causing SBP + shock)
cyst haemorrhage
ovarian torsion
What is the action for ovarian cysts 1
Complex ovarian cysts should be biopsied to exclude malignancy
complex: filled with blood/ walls inside of them/ solid
Ovarian enlargement: management
The initial imaging modality for suspected ovarian cysts/tumours is ultrasound. The report will usually report that the cyst is either:
simple: unilocular, more likely to be physiological or benign
complex: multilocular, more likely to be malignant
Management depends on the age of the patient and whether the patient is symptomatic. It should be remembered that the diagnosis of ovarian cancer is often delayed due to a vague presentation.
Premenopausal women
a conservative approach may be taken for younger women (especially if < 35 years) as malignancy is less common. If the cyst is small (e.g. < 5 cm) and reported as ‘simple’ then it is highly likely to be benign. A repeat ultrasound should be arranged for 8-12 weeks and referral considered if it persists.
Postmenopausal women
by definition physiological cysts are unlikely
any postmenopausal woman with an ovarian cyst regardless of nature or size should be referred to gynaecology for assessment
1st line: US
for complex cysts + post menaupausal women, ararnge biopsy
for simple cysts, repeat US in 2 months

-> infertility
Explain the menarche cycle in terms of ovarian and uterine cycles, what is the variation in cycle length
ovarian:
1. follicular (1-13)- LH surge day 12/13 so 36 hours= preovulation
2. ovulation (14)
3. luteal (15-28)- LH stimulates corpus luteum to release progesterone
uterine/ hormonal:
menses (1-5): decreased oestrogen + progesterone= breakdown of lining
proliferative (6-14): increased oestrogen= build up of lining
secretory (15-28): increased progestrone- peaks on 21st day= maintenance of lining
23-35 day
FOL ovarian
MPS uterus
What is a marker for ovulation 1
midluteal progesterone, 7 days before end of cycle eg if ycle is 28 days long then on day 21 and if cycle is 35 days long then on day 28

What is the management for nephrolithiasis 5
- NSAID-diclofenac for pain, IV if admitted and if not fixing issue, IV paracetomol
- watchful waiting if less than 5mm
- tamsulosin to aid spontaneous passage of stones if <10mm for ureteric stones only
- surgical interventions: lithotripsy or Percutaneous nephrolithotomy if over 20mm
- reduce reoccurrence- potassium citrate (reduces uric acid) and thiazide diuretics (reduces calcium), encourage water and low salt diet (sorts out dehydration)
What is endometriosis?
- endometrial cells growth and form linings outside of the uterus eg ovaries, fallopian tubes, uterosacral ligaments
- these cells in the endometrium respond the the mentrual cycle each month and bleed
- but with nowhere for the blood to go, there is inflammation and scar tissue formation which is painful

Rotterdam criteria (need to have 2+/3)= clinical diagnosis
hirsutism
menstrual changes
polycystic ovaries
What is the pathophys of PCOS 4
- No increase in progesterone from corpus luteum= increase in GnRH
- this causes high levels of androgens (LH mainly)
- high androgen levels promote hirsutism and insulin resistance
- therefore, there are high levels of insulin produced, which increases LH production
What are the symptoms of PCOS 6
subfertility
hirsutism (acne, facial hair)
oligo/ amenorrhoea
mood swings
insulin resistance
acanthosis nigricans
SHOMIA

in ampulla (in fallopian tubes)
What is the ix for ectopic pregnancy?
- pregnancy test= positive
- transvaginal US (adnexal mass that moves separately to the ovary)
What is the mx for ectoptic pregnancies 3
- CONSERVATIVE: if asymptomatic, size <35mm, no fetal heartbeat, hCG under 1000
= regular hcg monitoring
monitor over 48 hours to check B hcg- but no admission, only trips to hopsital for blood tests in expectation that it will spontaneously resolve
- MEDICAL: if some pain, size <35mm, no fetal heartbeat, hCG under 1500
= give methotrexate and attend follow up to monitor hcg, can give another dose of methotrexate if fails to treat ectopic pregnancy. Advise not to get pregnant within 3 months due to tetarogenic nature of methotrexate
only do this if patient can attend follow up in 4 days and after thsi get weekly b hcgs until back to normal
- SURGICAL: if lots of pain, size >35mm, fetal heartbeat present, hCG over 5000
=salpingectomy (fallopian tube containing the ectopic pregnancy is removed which reduces risk of future ectopics reoccuring)
only surgical needs anti-D immunoglobulin (not even methotraxate)
Explain the types of miscarriage 5
- Missed miscarriage – the fetus is no longer alive, but no symptoms have occurred (transvaginal US dx no foetal heart activity and CRL >7mm, give Mifepristone then 48 hours later misoprostol then within 48 hours bleeding should start)
- Threatened miscarriage – painless vaginal bleeding with a closed cervix and a fetus that is alive in first 24 weeks of gestation, goes on to produce a viable baby
- Inevitable miscarriage – heavy vaginal bleeding, painful, clots with an open cervix which is a sign of physiological expulsion of the pregnancy from the uterine cavity- will progress to complete/ incomplete miscarriage
- Incomplete miscarriage – retained products of conception remain in the uterus after the miscarriage (US shows mixed echos in uterine cavity)
- Complete miscarriage – a full miscarriage has occurred, and there are no products of conception left in the uterus (US shows empty uterus, pregnancy test in 3 weeks to confirm)
What is miscarriage, when does this usually occur and why and risk factors 4
spontaneous abortion
first trimester before 12 weeks
50% are due to chromosomal abnormalities
Rfx: 35+, previous miscarriage, poor lifestyle eg smoking/ alcohol, med conditons eg uncontrolled diabetes
What is recurrent miscarriage and causes 4
3+ consecutive losses
-> smoking
-> chromosomal abnormalities
-> poorly controlled diabetes
-> PCOS
What is mx for incomplete miscarriage? 5
miscarriage cannot be stopped/ prevented so mx is to completely remove foetal material
1. wait for a spontaneous miscarriage (wait 1-2 weeks for completion)
2. if incomplete then single dose misoprostol vaginally/ oral (prostaglandic analogue= softens and dilates the cervix)
3. analgesia and antiemetics
4. surgery: vacuum aspiration
5. pregnancy test at 3 weeks

- regular self monitoring of blood glucose and targets required to meet: fasting 5.3, 1 hour postprandial 7.8, 2 hours 6.4
- just diagnosed seen within a week at diabetes and antenatal clinic
- if at the time of diagnosis the fasting glucose level is >= 7 mmol/l insulin should be started
What are the trimesters of pregnancy 3
first trimester – conception to 12 weeks
second trimester – 13 to 27 weeks. third trimester – 28 to 40 weeks.
What is the law on termination of pregnancy
1967 abortion act
24 weeks and under (23 +6) with risk to mums physical or mental health or foetus would likely be handicapped
2 registered medical practitioners need to sign a legal document
When is a pregnancy considered viable
when a fetal heartbeat is visible arond 5-6 weeks after conception
What is important to note about rhesus D negative women who have a termination of pregnancy or miscarriage
if after 10 weeks, then give anti-D prophylaxis, otherwise no need
What is the mx for terminatin of pregnancy
- mifepristone (an anti-progestogen, often referred to as RU486) followed 48 hours later by prostaglandins (e.g. misoprostol) to stimulate uterine contractions.
-> Give analgesia and anti-emetics too
-> before 10 weeks can be done at home, after 10 weeks, done in hospital - pregnancy test in 2 weeks to confirm pregnancy has ended
- alternatively, they can choose a surgical method= manual vacuum aspiration
women are free to choose the method of termination
What are the risk factors of gestational diabetes? 2

if endometritis then emergency to hospital and give IV clindamycin and gentamicin until fever subsided for 24 hours
What is the guidance on maternal group B strep infections and why?
-> women who’ve had GBS in a previous pregnancy should be offered intrapartum antibiotic prophylaxis (IV benzylpenicillin during labour)
-> women who have fever during labour should be given IV benzylpenicillin too
-> woomen in preterm labour should be offered this too
-> this is not given to all mums, even if it is requested
-> baby is monitored for 12 hours if mum has had previous GBS with other births
GBS is contained in many mothers bowel/ vaginal flora and infants can be exposed to this during labour and develop serious infections as a result
What is the ix, mx for UTI in pregnant women 3 Why do we treat asx bacteruria
1st line nitrofurantoin (not given in final trimester due to risk of neonatal RBC haemolysis) for 7 days
2nd line amoxicillin for 7 days
trimethoprim is CI for first trimester, but generally avoided throughout
1/2nd trimester: nitrofurantoin 7 days
3rd trimester: cefalexin 7 days
-> send intial urine culture
-> should send off culture after treatement to check if the abx have worked
always treat as it can become pyelonephritis which can have an impact on the fetus (early birth/ poor growth). A regular UTI cannot affect the fetus unless it caues kidney issues which is what abx tries to prevent
What is the mx for Puerperal pyrexia
-> if endometritis suspected, pt referred to hospital for IV clindamycin and gentamicin until afebrile for more than 24 hours
When should urine cultures be sent for UTIs 3
65+
haematuria
pregnancy
paediatrics
Why is varicella zoster dangerous in pregnant women?
-> congenital varicella syndrome/ severe neonatal varicella infection for baby
-> varicella pneumonitis/ hepatitis/ encephalitis for mum
What is congenital varicella syndrome/ fetal varicella syndrome? 5 When does it occur?
skin scarring,
eye defects (microphthalmia- one/both of babys eyes are small),
limb hypoplasia,
microcephaly
learning disabilities
Varicella
very small limbs
abnormal eye: microphthalmia- one/both of babys eyes are small
red lesions of scarred skin
intellectual- learning disabilities
cephaly is micro
when infection in first 28 weeks of gestation
What are the ix that can be done for varicella zoster in pregnancy 1 and what is the condition for this
- check VZV IgG levels (if positive, mum is immune and has antibodies)
only if mother is unsure about having chickenpox as a child
What is the mx for varicella zoster in pregnancy 3
- Give oral acyclovir as prophylaxis between day 7-14 after chickenpox exposure (apparently more effective compared to immediately)
- once chickenpox rash appears, give oral aciclovir if it is within 24 hours and if they are more than 20 weeks gestation
- once baby delivered, monitor and give IV acyclovir
What is uterine hypoactivity and why is this a problem
2 or fewer contractions in 10 minutes and each lasting less than 40 seconds
leads to suboptimal progress during labour
What is Oligohydramnios and causes 3
low volume of amniotic fluid surrounding fetus at pregnancy
- rupture of membranes= fluid loss
- fetal growth restriction (baby produces less urine= less fluid)
- things that reduce baby’s ability to wee: eg renal agenesis in potter sequence
What is the ix 1 and mx 1 of oligohydranmios
US: max vertical pocket <2cm and amniotic fluid infex <5
therapeutic amnioinfusion
How does the process of amniotic fluid work?
amniotic fluid is initially produced by mother until 33 weeks of gestation. This declines until there is only 500ml at term
Fetus breathes and swallows the amniotic fluid which gets processed and the fetus wees out, eventually replacing the amniotic fluid with fetal urine
What is Polyhydramnios and causes 3
abnormally large level of amniotic fluid during pregnancy
-> maternal diabetes
-> macrosomia
-> fetal infections (TORCH)
What is the mx for Polyhydramnios 1
only if so severe that it is causing mother SOB, then aminoreduction (needle to drain some fluid)
What is a breech mapresentation?
bottom is closest to uterus
What is uterine rupture
and complications 2 and symptoms 2
rupture of myometrium of uterus during a labour contraction whilst the baby is inside
complication: this is an issue because the fetus is deprived of oxygen and mum can get peritonitis- fatal for both
vaginal bleeding and ceasing of uterine contractions
rfx: previous c-section
What is Cephalopelvic disproportion
when baby’s head doesn’t fit through opening of pelvis
What is the mx for breech malpresentation? 2
if still breech at 36 weeks NICE recommend external cephalic version (ECV)- CI= ruptured membranes and multiple pregnancy
if baby still breech then discuss delivery options eg planned caesarean (which carries reduced reduced mortality for babies in breech)
How is uterine rupture managed? 2
emergency caesarean section to remove the baby ASAP
may need a hysterectomy to remove uterus or repair uterus in same surgery as c section
main risk factor for uterine rupture and investigations
previous caesarean section
CTG: will be abnormal- fetal bradycardia
What are the 3 stages of labour?
- onset of true contractions to 10cm cervical dilation
- from 10cm until baby is delivered
- from baby delivered to placenta delivered
What are braxton hicks contractions? How to tell the difference between this and true contractions
irregular contractions of uterus in 2/3 trimester which are NOT true contractions and do not indicate onset of labour
-> comparatively, true contractions progress and become regular
What are the 4 signs of labour
Show (mucus plug from the cervix falls out)
Rupture of membranes
Regular, painful contractions
Dilating cervix on examination
What is classed as prematurity and what is classed as unviable
premature: before 37 weeks
non viable: below 23 weeks
What is prophylaxis for preterm labour 2
- vaginal progesterone (prevents cervix contracting)- short term eg enough time to give steroids and then do c-section
- cervical cerclage (stitch in cervix to keep it closed which is then removed in labour) can be inserted at week 14
What are the instruments that can be used to help in labour? 2 complications of these?
- ventouse (suction cup)- Cephalohematoma or caput succedaneum
- forceps- CN 7 palsy
What are the forms of pain relief in labour? 3
- conservative: perianal and fundal massage, TENS (transcutaneous elective nerve stimulation)
- meds: paracetomol in early labour, entonox (NO + O2 gas), IM pethidine (2 boluses max)
- epidural anaesthesia= CI in fetal distress and doac/ low platelets (risk of bleeding) (SE: urine retention, hypotension, headache)
What is shoulder dystocia, comp, mx2
failure of the anterior shoulder to pass under the symphysis pubis after the head has been delivered
need to deliver within 4 minutes to prevent fetal hypoxia and brain damage
-> McRoberts position
-> superpubic pressure to rotate and adduct baby’s shoulders to make the shoulders closer together for shoulders to pass through
What is an umbilical cord prolapse and sx 2
cord descends before the baby which is an emergency (as it can lead to compression of the cord AND cord exposed to outside temp= vasocontriction= fetal hypoxia)
sx: visible cord, fetal bradycardia
What is the tx for cord prolapse 4
A-E assessment
1. go on all 4s to reduce pressure on cord or trendelenburg position to have feet higher than head to releive pressure
2. can give tocolytics to buy time for c-section as it reduces uterine contractions -terbutaline
3. can catheterise + retrofill the bladder with saline (elevates the presenting part= feels better)
4. c-section needed (cat 1 if fetal distress and cat 2 otherwise)
What is PPROM and causes 4

- if doubt, IGFBP-1 test (should be +)
What is the mx for PPROM? 5
- 10 days oral erythromycin QDS 250mg to prevent chorioamnionitis
- antenatal steroids if before 36 weeks (develop fetal lungs and reduce resp distress)- 2 doses IM betamethasone 24 hours apart if beteeen 24 and 34 weeks
- IV magnesium sulfate to protect fetal brain from cerebral palsy if before 34 weeks (given within 24 hours of delivery of preterm less than 24) only IF labour started
- delivery plan for 34 weeks with expectant mx if no other contraindicaitions to this-planned preterm dilvery due to increase risk of chorioamnionitis
- admit for 72 hours to monitor for any infections
What is a note about giving magnesium sulfate to preterm labour mothers?
magnesium toxicity
signs: reduced tendon reflexes (esp patella), reduced resp rate, reduced BP
What is tocolysis, example and its purpose
using meds to stop uterine contractions eg nifedipine
-> used to delay delivery (SHORT TERM) and buy time for further fetal development/ to give steroids
-> given between 24 to 33+6 weeks
How does fetal monitoring occur?
CTG
How does CTG work??
-> uses doppler sound waves to check when the baby’s heart moves
-> this tracks the baby’s heart rate
What are the components of CTG 7
DR C BRAVADO
define risk
contractions 3-5 times in 10 mins
baseline (heart) rate
variability: how much fluctuation from baseline
acceleration
deceleration
overall/ other
How to define risk of pregnancy via CTG and action for high risk
LOW risk: regular contractions, HR 110-160, variability 6-25, accelerations present, early decelerations
HIGH risk: brady/tachycardia, variability <5 (for less than 40 mins= sleeping fetus), no accelerations, late/ variable decelerations
-> consider fetal scalp sample and if low pH, it indicates hypoxia= needs immediate c-section
What is a normal variability, acceleration and deceleration in CTG
variability= fetal heart rate fluctuation from one beat to the next, normal is between 6-25 bpm
accelerations= when fetal heart rate is 15 or more bpm ABOVE its baseline for 15+ seconds
decelerations= when fetal heart rate is 15 or more bpm BELOW baseline for 15+ seconds

oestrogen: proliferates endometrial cells for ovulation and builds endometrial lining after menstrual cycle
progesterone: increases uterine mucus secretion and maintains endometrium and causes smooth muscle relaxation (why it drops for menstruation to start)
LH: acts on theca cells which stimulates oestrogen production and stimulates release of egg during ovulatoin
FSH: acts on granulosa cells for folliculogenesis
Explain 3 types of natural contraception
-> condom use
-> breastfeeding (for up to 6 months if period hasn’t come back to delay ovulation)
-> tracking periods and when in the cycle you are most fertile
What are the shorter acting contraceptives 3
-> COCP (CI in CV disease, HTN, VTE hx, heavy smoker, breastfeeding, <6 weeks postpartum, migraines, breast cancer)
-> POP
-> HRT contraceptive patch (releases osteogen and progesterone- same 21/7 day cycle, better for people who want COCP but forget to taken pills)
What are the longer acting contraceptives 4
-> depo provera (medroxyprogesterone injection)
-> IUS (hormonal)
-> IUD (copper)
do not give IUS/D if 48h-4 weeks postpartum
-> nexplanon implant (implant in arm and releases progesterone, lasting for 3 years)
What are the sterilisation options 2
-> vasectomy (males)- reversible
-> tubal ligation (females)
What is the UK MEC guidance for contraceptions and how is it calculated?
UKMEC 1: no restriction
UKMEC 2: benefit generally outweighs the risk
UKMEC 3: theoretical or proven risk generally outweighs the benefit
UKMEC 4: contra-indicated
-> based on patient and their co-morbidities
How are COCPs taken? Example
21/7 cycle
-> 21 days of taking the pill at the same time each day
-> 7-day break where they will have a period-like withdrawal bleed
-> 3 monthly if irregular periods and monthly if regular
Microgynon 30
continous COCP taken for post menopausal women
What are the screening tests for infections/ genetic conditions for a fetus and when are they done
12 weeks: chorionic villus sampling
15+ weeks: amniocentesis to identify any chromosomal conditions eg downs/ pataus/ edwards or genetic cond eg cystic fibrosis/ sickle cell
15+ weeks: NIPT (alongside amniocentesis)- sample mums blood for cffDNA (very sensitive for Downs)
What are the two phases of stage 1 labour
latent phase = 0-3 cm dilation, normally takes 6 hours
active phase = 3-10 cm dilation, normally 1cm/hr
What are the two phases of stage 2 labour
‘passive second stage’ absence of pushing
active second stage’ refers to the active process of maternal pushing- can give oxytocin as part of hte active labour maangement
What are the indications of inducing labour? 3 what are the risks? 2
- prolonged labour
- maternal risks eg obesity/ preeclampsia/ gestational/ PPROM
- uterine hyperstimulation (more than 6 contractions in 10 mins)
- fetal ischaemia
Explain the two ways of labour induction
if bishops score < 6= vaginal prostaglandin or oral misoprostol
bishops >6= amniotomy with an amnihook and IV oxytocin
What does the bishops score measure and explain the scoring
cervical ripeness
1-5= unripe, unlikely to spontaneously induce= induce labour
5-7= intermediate
7+= ripe, likely to spontaneously induce, expectant mx
What can be done for a breech baby to turn them head first?
36 weeks, external cephalic version
-> try to turn the baby into a head-down position by applying pressure on your abdomen
What are the risks of breech baby vaginal delivery? 2
-> cord prolapse
-> dislocated hips
How to know what to prescribe for HRT
HRT (for perimenopausal sx management)
needs to be combined if they have a uterus
topical if sx are only vaginal, oral if sx are systemic
transdermal for systemic sx but risk of VTE (still needs to have a source of progesteron eg mirena coil)
CI in hormonal cancers and unexplained PMB
What is the implication of chlamydia contraction during pregnancy 2
neonatal conjunctivitis/ pneumonia
What are the neonatal complications of rubella infection in pregnancy and when can it be contracted
congenital deafness, cataracts and heart disease (PDA + pulmonary stenosis)
in the first 20 weeks of pregnancy
What are the complications of CMV infection during pregnancy
hearing/ vision loss
microcephaly
learning disabilities
seizures
fetal growth restriction
What are the symptoms of toxoplasmosis infection in pregnancy on the neonate and how does this spread
triad:
intracranial calcificaiton
hydrocephalus
chorioretinitis
faeces of cat more likely than a human
What are the neonatal complications of parovirus b19 infection during pregnancy
miscarriage/ fetal death
severe fetal anaemia
hydrops fetalis
Mx for reduced/ no fetal movements
If not felt movement by 24 weeks= urgent referral to fetal med unit
if reduced movement:
after 28 weeks, use handheld dopper to confirm fetal heartbeat and if this is NOT detected then immediate US. IF detected then cardiotocography for 20 mins to monitor heart rate
Mx for pregnancy related nausea 4
- In mild-moderate N+V, lifestyle advice + diet modificaton should be offered first (including ginger)
- first line meds is cyclizine/ promethazine
- second line meds is metoclopramide/ ondansetron
- if severe sx of dehydration then admission to hospital
infertility
infertility= failure to achieve a pregnancy after 12 months or more of regular UPSI (primary= couples that have never conceive, secondary= conceived already but struggling to again)
ovarian hyperstimulation syndrome cause, sx,
normally going through IVF and having injections
sx: n/v, bloating, SOB
What is the pathological basis behind the shortness of breath in this conditon?
- Hyperstmulated ovaries release vasoactve mediators
- Increased capillary permeability causes fluid shift
- SOB due to pleural effusion
(can have ascites/ pericardial efusions due to efusion in respectve cavites)
COCP and POP missed pill rules
If 2-7 pills have been missed (72 hours or more since the
last pill in the current pack was taken) in week 1/2/3 after HFI
- Emergency contracepton is not required if there was
consistent, correct use in the previous 7 days
- Avoid sexual intercourse or use a barrier method of
contracepton untl 7 consecutve pills have been taken:
(this is overcautious, but is a back-up in case of
subsequent incorrect use.)
If 2+ pills missed in week 4, barrier for 7 days and omit next HFI period
if 7+ pills missed, start like its new, take a pregnancy test before this and barrier for 7 days
If 1 pill missed regardless of week, take missed pill ASAP and no emergency contraception required as long as had 7 days of correct use of pill
emergency contraception only required if 2+ pills missed and UPSI occured during HFI or week 1
if 1 pill missed on POP, no emergency contraception needed, take pill ASAP and use barrier contraception for 48 hours
investigations for hyperemesis gravidarum
immediate ix:
1. urine dipstick: to check for ketones 2. bloods: FBC, TFT (hypo= nausea), UE
mx for nausea in pregnancy
- In mild-moderate N+V, lifestyle advice + diet modificaton should be offered first (including ginger)
- first line meds is cyclizine/ promethazine
- second line meds is metoclopramide/ ondansetron
- if severe sx of dehydration then admission to hospital: give IV saline with potassium , thiamine, b6
What are the risk factors for hyperemesis gravidarum
- first pregnancy
- multiple pregnancy
- prev phx of HG
- molar pregnancy
contraceptives time until effective
POP- 2 days
COCP/IUS/implant/depot- 7 days
IUD- immediately
Tell me about emergency contraception
levonogesterol 1.5mg to be taken within 72 hours of UPSI
IUD= up to 5 days
ullipristol= 30 mg up to 120 hours/ 5 days after UPSI
