diseases Flashcards
why does ovarian torsions occur
due to hypermobility of the ovary or
adnexal mass, most commonly a dermoid cyst
investigation for ovarian torsion
bloods- raised white cells
US- initial imaging of choice (whirlpool sign)
CT
management of ovarian torsion
urgent surgery
where is HCG secreted from
syncytiotrophoblast
it acts to maintain the production of progesterone by the corpus luteum in early pregnancy
what type of origin is ovarian cancer
epithelial
risk factors for ovarian cancer
family history: BRAC
many ovulations: early menarche, late menopause, nullipartity
70 year old with dragging sensation down below and incontinence
uterine prolapse
management of prolapse
lifestyle- wt loss, stop smoking, avoid heavy lifting
oestrogens- only is symptomatic atrophic vaginitis
pelvic floor exercises
pessaries- if unfit for surg
surgical
treatment of urge incontinence
mainly lifestyle and bladder retraining
medications- antimuscarinics (oxybutynin and tolterodine), B3 agonists
posterial tibial nerve stimulation
investigations for disrupted uterine bleeding
if regular cycle do a midluteal progesterone
if an irregular cycle doe a progesterone challenge test
hypothalamic causes for DUB
genetic causes
idiopathic hypogondaotrophic hypogondsim
kallmas syndrome- lack of smell
other factors- anorexia, bulimia
results in hypothalamic cause of DUB
low everything- GnRH, low FSH, low LH, low oestrogen and progesterone
results in pituitary caused DUB
high GnRH, low FSH, low LH, low oestrogen and progesterone
causes of pituitary DUB
drugs- dopamine antagonists
sheehan’s syndrome
prolactinoma
pituitary adenoma
ovarian causes of DUB
PCOS
premature ovarian failure
congenital
tubal disease
criteria for diagnosing PCOS
rotterdam criteria
1. oligo/amenorrhoea
2. hyperandrogenism- hirsutism (increased free testosterone)
3. evidence of Polycystic ovaries on USS
clinical features of PCOS
obesity
hirsutism
acne
cycle abnormalities
infertility
insulin resistance
treatment of PCOS
lifestyle- wt loss
NOT wanting a family: OCP (dianette if hirsutism), metformin
wanting a family: clomifene citrate +/- metformin, (2nd line gonadotrophin therapy, 3rd line IVF/laparoscopic drilling)
what is premature ovarian failure
menopause <40 years old
decrease in oestrogen
increase in FSH >30
causes of premature ovarian failure
idiopathic
chemo/radiotherapy
genetic: turners syndrome, fragile X
treatment of premature ovarian failure
HRT
infective causes of tubal disease
PID
transperitoneal spread
post-procedure
non-infective causes of tubal disease
endometriosis
surgical (sterilisation/ectopic)
fibroids/polyps
congenital
presentation of PID
fever, pain, discharge, cervical excitation, deep dyspareunia
complications of PID
infertility
hydrosalpinx
ectopic pregnancy
chronic pain
abscess
management of PID
High risk of GC or <18 years – IM ceftriaxone
500mg IM single dose then doxycycline 100mg bd + metronidazole 400mg bd (14 days)
Low risk of GC - Ofloxacin 400mg bd + metronidazole 400mg bd (14days)
endometriosis presentation
dysmennorrhoea, menorrhagia, dyspareunia, painful defecation, pelvic pain is cyclical (tissue under hormonal influence), bloating and distension
investigations for endometriosis
USS- chocolate cysts on ovary, diagnostic laparoscopy- definitive investigation
treatment of endometriosis
- COCP/mirena IUD + NSAIDs
- GnRH agonist eg goserelin- not if they want to get pregnant
- laparoscopic ablation
what is adenomyosis
endometrial glands and stroma within the myometrium also presents with menorrhagia and dysmenorrhoea (boggy uterus)
what is leiomyoma
benign smooth muscle
growth is oestrogen dependent
presents with pain, menorrhagia, infertility
what is endometritis
plasma cells in endometrial stroma
infective until proven otherwise
