uterine artery embolization
what is endometriosis?
the presence of endometrial glands and stroma in locations other than the uterine cavity
suggest a class of drug that are given before surgery for tumour shrinkage in patients with uterine fibroids
gonadotropin-releasing hormone analogues
what are theca-lutein cysts?
they often occur as multiple ovarian cysts due to gonadotrophin stimulation and are associated with choriocarcinoma and moles
the theca folliculi comprise a layer of the ovarian follicles - they appear are the follicles become tertiary follicles.
what is the main type of cancer of the placenta?
choriocarcinoma - a malignant, trophoblastic cancer. it is also classified as a germ cell tumour and may arise in the testis or ovary.
there will be haematogenous metastases to the lungs and brain
what are the most commonly involved sites in endometriosis?
- ovares
2. pouch of douglas
what is adenomyosis?
endometriosis involving the uterine myometrium due to hyperplasia of the basalis layer of the endometrium.
what is the role of progesterone analogues in the medical treatment of endometriosis?
the progesterone analogues act by decidualization and atrophy of the endometrium
what is a dermatoid cyst?
an ovarian cyst that is described as a mature teratoma
ovarian torsion usually occurs on top of ovarian masses measuring more than how many centimetres in diameter?
5
what is the management of symptomatic cysts larger than five centimeters?
laparoscopic surgical removal
what is a chocolate cyst?
a cystic formation at the ovaries in endometriosis due to growing and shedding of the ectopic endometrium
endometriosis will decrease the risk of ovarian cancer - true or false?
fasle. endometriosis will increase the risks
what is it called when endometriosis involves the uterine myometrium?
adenomyosis
what is the diagnostic test of choice for evaluating ovarian pathology?
abdominal ultrasound
what is the most common tumour in females?
uterine leiomyomas
what typically happens to uterine fibroids after menopause?
they will typically shrink due to the decrease of oestrogen.
uterine fibroids are also known as leiomyomas and are benign smooth muscle tumours (commonest tumour overall in females). they are dependent on oestrogen for their growth and can (rarely) progress to leiomyosarcoma.
submucosal fibroids will present with abdominal vaginal bleeding and menorrhagia or menometrorrhagia.
subserosal fibroids can grow and cause pressure effects on surrounding organs, and can sometimes become parasitic fibroids that break away form the uterus and attach to other organs.
treatment is with myomectomy, uterine artery embolization or hysterectomy if childbearing is complete

what is the mode of action of the oral contraceptive pill in the medical treatment of endometriosis?
ovarian suppression
what is an endometrioma?
a mass resulting from the entrapment of cyclic slough of endometriotic implants, through cyst formation

A 33 y/o woman presents who was well throughout pregnancy. Has spontaneous labour at 38 weeks, which progresses well but mom has fever. The baby is born, distressed with poor APGAR score and sent to the neonatal unit. In the neonatal unit: baby resuscitated, well after 5 days, no malformations, home after 2 weeks. Placenta examined (routine if baby is sent to neonatal unit): membranes contain neutrophils, trilobed nucleus is easily deformable and allows them to move easily into tissues, phagocytose (ingest) and destroy microorganisms.
- Diagnosis?
- How does an ascending infection affect babies brains?
- Acute chorioamnionitis (acute inflammation)
neutrophils present in membranes, cord and fetal plate of placenta. It is an ascending infection in which bacteria are typically perineal or perianal flora (e.g E.coli) which ascend vagina and get into the amniotic sac.
- neutrophils produce cytokine ‘storm’ which activates some brain cells, when then get damaged by normal hypoxia of labour.
what are the screening programs in place for breast cancer?
- mammogram every 3 years
targets women who are aged between 50 and 70. there is also clinical surveillance 5 years below the age any one in the family had been diagnosed with breast cancer.
it will detect 5 cancers per 100 screened and will benefit 30% reduction in mortality
what are some prevention methods used for breast cancer?
prophylactic mastectomy
removes most but not all of breast and significantly reduces the risk in women with a family history of cancer and women with the BRCA1 mutation (down to 5%)
in a total mastectomy more tissue will be removed in comparison say to a subcutaneous mastectomy
what is the management used for breast cancer?
- surgery

invasive squamous carcinoma of the cervix
smears collect cervical cells for microscopy for dyskaryosis. women with borderline or mild changes are tested for high-risk HPV and if positive, referred for colposcopy regardless of HPV status.
HIV positive women should have annual smears
