Gynaecological Conditions Flashcards
What is hyperemesis gravidarum? (HG)How does it come about?
1 in 750 women. Most: moderate NV of pregnancy- (NVP)
Xs N+ vomitting in early pregnancy so severe to cause & severe dehydration, wt loss or electrolyte distrurbances.
Aetio: asc w/ ⬆️ levels of hCG.
assc w/ ketosis
RF for hyperemesis gravidarum?
How would u recognise it from the Hx and O/E?
Multiple /molar pregnancies, gestational trophoblastic disease, previous HG, ⬆️BMI, nulliparity, ⬇️maternal age, hyperthyroidism. UTI.
1% of women.
Hx: severe N+V, anorexia, wt loss.
O/E : general; signs of dehydration: dry mucous membranes, tachycardia, postural hypertension.
How would u investihate HG,?
Urine: asses degree of ketosis, exclude UTI (RF)
Bloods: FBC(haemoconcentration) , U&Es, LFTs, TFTs
USS: exclude multiple pregnancy and gestational trophoblastic disease
How would u manage HG?
Admit, rehydrade IV (normal saline) -dextrose contraindicated (Hartman’s) + antiemetics - cyclizine, prochlorperazine, metaclopramide.
Ondasteron + PO thiamine (to prevent neuro complications of vit depletion–> Werinkes Encephalopathy)
Consider thrombophylaxis.
Severe: steroids; prednisolone., total parenteral care-rare
Psychological support- emotional/ social probs.
What are some complications of HG?
Mallory-Weiss Tear, Werinke’s Wncephalopathy (thiamine deficiency) , muscle wasting, VTE (dehydration) , electrolyte disturbance, renal impairment.
Prognosis: complications rare w/ appreciate treatment.
Whats gestational trophoblastic disease?GTD.
Trophoblastic tissue( part of blastocyst that invades endometrium) –> more aggresive- HCG ⬆️⬆️, can also be choriocarcinoma.
O/E- uterus large, pre-eclampsia & hyperthyroidism.
Hx vajj bleeding + may be heavy. Hyperemesis
Routine USS- detected.
“Snowstorm appearance”. Diagnosis- histologically.
How do u manage GTD?
Trophoblastic tissue suctioned out by suction curettage- ERPC + diagnosis confirmed histologically.
What are some complications of GTD,??
Recurrence of molar pregnancies.
What happens in diabetes in pregnancy? What are some associations/RFs?
Epidem: 2-5%, 90% of pregnancies.
Pre-existing or new onset diabetes- gestational.
Aetiology: pre-existing: type1: F of pancreas to produce insulin. Type2: relative insulin deficiency assc w/ ⬆️ peripheral insulin resistance.
Gestational DM: altered glucose tolerance in pregnancy.
Assc:
⬆️ maternal age, ethnicity: S. Asian, middle eastern, afro-Caribbean)
Obesity, smoking, PCOS( polycystic ovarian syndrome) , FHx, previous macrosomic baby.
What findings are there on Hx and O/E?
for GDM?
Hx: pre-existing- known to mother
GDM: asymptomatic, detected on scan.
Abdo: fundal height (macrosomia/ polyhydraminos)
Whats the pathophysiology of GDM?
Type1: autoimmune destruction of pancreatic islet cells
Type 2: genetic component + i fluence of age+ obesity on peripheral insulin resistance.
GDM: ⬆️ insulin resistance in pregnancy (⬆️ secretion of insulin antagonists, including HPL-human placental lactogen- glucagon + cortisol, altered carbs metabolism, Failure of normal pregnancy incease in insulin production.
Fetus: hyperglycemia in early pregnancy may affect development- cong. abn. Hyperglycemia causes fetal hyperinsulinaemia + macrosomia.
Neonatal: hypoglycaemia- withdrawal of maternal glucose while fetal insulin high- ⬆️⬆️ insulin secretion since maternal glucose passes through placenta- fetus tries to compensate and store the extra glucose.
How would u investigate GDM?
Delivery: aim for delivery-38 weeks- sliding scale in labour
Pre-existing: detailed anomaly scan, fetal cardiac scan, opthalmic examination.
GDM: screening(universal or selective) Glucose tolerance test at 26-28/40 weeks.
How would you manage diabetes in pregnancy?
Pre-existing: preconceptual: optimisation of glucose control.
Medical: optimise diet, consider converting oral hypoglycaemics to insulin. Likely to require incrasing doses of insulin.
Pregnancy: capillary blood glucose monitoring, monitor for pre-eclampsia, serial USS for fetal growth- macrosomia?
Delivery: sliding scale in labour
Postpartum: return to pre-pregnancy doses.
GDM:
Medical- diet control, persistent hyperglycemia may require insulin tx.
Pregnancy/delivery: as for pre-existing.
Postpartum: stop insulin after delivery. Fasting glucose 6/52 postpartum.
What are some complications of Diabetes in pregnancy? Whats the prognosis?
Maternal: progression of pre-existing nephropathy/neuropathy/retinopathy, miscarriage, pre-eclampsia, operative delivery.
Fetus/neonate: congenital abn.(pre-existing only),fetal death, polyhydraminos, polycythaemia, macrosomia (+traumatic delivery) resp distress syndrome, neonatal hypoglycaemia, neonatal jaundice.
Prognosis:
Dependent on adequate control.
GDM: 70% occurance in further pregnancies.
⬆️40-60% risk for type 2 DM
What happens in eclampsia?
Definition+ O/E :Grad-mal seizures on a backround of pre-eclampsia.
RF: pre-eclampsia
4.9 per10000 maternities. Postpartum more.
Hx: sx of impeding eclampsia: headache, epigastric tenderness, visual disturbance, oedema, hyperflexia, clonus.
Patho: unclear- cerebral vasospasm, hypertensive encephalopathy, tissue oedema, ischamia + Haemorrhage proposed.
Inv: as for pre-eclampsia: bloods: FBC, clotting, U&Es, urate, LFTs, G+S, consider ABG.
Urine: protrinuria??
Imaging: post-seizure: CT head, CXR if chest signs.
How would u manage eclampsia? What are some complications?
ABC
Apply O2, maintain patency :NG tube? Ventilation
C: left tilt, large bore IV access, evaluate pulse and BP.
Drugs: IV MgSO4- monitor UO, patellar reflexes, resp rate.
Recurrent seizures: further magnesium sulphate, diazepam, IPPV- intermittent +ve pressure ventilation + muscle relaxation.
Post seizure: asses chest, control BP
Deliver baby when mum stabilised.
Compl: cardiac arrest, death, permanent CNS damage - cortical blindness, CVA- cerebrovascular accid, DIC- disseminated intravascular coagulopathy, renal F, ARDS.
What happens in Pelvic Inflammatory disease ? (PID)
- inflammation and infex arising from endocervix leading to endometritie, salpingotis, oophoritis, pelvic peritonitis and tube-ovarian and pelvic abscesses.
Chlamydia, gonococcoal infx common, bacterial vaginosis.
Patho: infx ascends, fallopean tubes (FT) damaged. - inflm- destroys the cilia in FT- scarring of tubal lumen. - pocketing within lumen…- ectopic..
Peritoneal inflammation: severe infx: mucopurulent discharge exudes through fibrial end of FT. –> scarring and adhesions b/w pelvic structures. –> omental adhesions..
Perihepatic adhesions: fitz hugh curtis syndrome- violin string appearance at laparoscopy.
What else could cause perihepatitis leading to adhesions b/w the liver and peritoneal structures?
Chlamydia and gonorrhoea
SandS of PID
🔹Abdo, pelvic pain and dyspreunia,
🔹mucopurulent vajj discharge, pyrexia >38,
🔸heavy/ intermenstrual bleeding,
🔹pelvic tenderness and cervical excitation during examination,
🔹tender adnexal or palpable pelvic mass,
🔸generalised sepsis in severe + systemic infx,
🔹Tubal damage–> tubal occlusions, abscess and hydrosalpinx.
How would u diagnose PID?
⬆️ WCC- neutrophilia- acute inflammatory D
⬇️ WCC- neutropenia- severe disease
⬆️ CRP/ESR
Adnexal mass on USs
What is the gold standard for diagnosing PID?
Laparoscopy- mild cases might not be obvious-
Also exclude other causes of pain; appendicitis, endometriosis, ovarian cyst
How would you treat PID?
When are people admitted?
Pregnancy test- ectopic !
Mild/ moderate- outpatient tx
1. Oral ofloxacin + metronidiazole
2. IM ceftriaxone(1) + oral doxacyclin + oral metronidiazole
3. Single IM caftriaxone + azithromycin.
Broader spec- PID+ chlamydia + gonorrhoea- triple Antibiotic therapy.
Hospitalisation + parenteralbtherapy
Admitted when:
Severe infx, adnexal mass suscpicious of abscess, generalised sepsis, poor respomse to tx,
Severevpelvic/ abdo pain requiring strong analgesics.
Principles of tx of severe PID???
Supportive care, strict fluid balanace, parenteral Antibiotics:
- Ceftiaxone IV/oral doxacyclin, + oral metronidiazole -24 hrs better–> switch to oral therapy for 14 days
- Clinamycin IV 3 times a day+ gentamicin iv followed by clindamycin/ oral doxacyclin + oral metronidiazole for 14days.
- Ofloxacin iv + metronidiazole iv 14 days.
In pregnancy: combo of cefotaxime + azithromycin + metronidiazole.
Surgical tx:
Ptx w/ pelcvic abscess / not responding to oral tx–> laparoscopy is warranted + used for exclusions.
Drainage of abscess + smts affected tube/ ovary might have to be removed.
What antibiotics should be avoided in pregnancy? When PID?
Doxycyclin, gentamycin, oflaxicin,
What should be included in pt counselling?
Partner + sexual contacts should be screened.
Risk of reinfx if partner not treated.
Barrier contraception used. ⬇️ risk of reinfx
Risk of tubal damage–> subfertility–> chronic pelvic pain, –> ⬆️ chances of ectopic.
Early + good tx will ⬇️ risk of subfertility.
If pregnant- early medical advice- might be ectopic
