GYN Flashcards
Differentials for regular menorrhagia
- primary dysfunctional uterine bleeding
- uterine leiomyoma
- uterine endometriosis
- secondary dysfunctional uterine bleeding.
Types of dysfunctional uterine bleeding
primary: anovular or ovular
secondary: bleeding disorder (Idiopathic thrombocytopenia, von willebrands diseasem or anticogulation therapy
Uterine Tenderness suspicious of?
adenomyosis
Investigations for heavy periods?
FBC - iron deficiency anaemia
TFT
USS- if indicated by bimanual examination (position size and number of fibroids)
endometrial biopsy- over 40 years of age because below 40 low risk of endometrial ca.
What drug treatment is available for the treatment of menorrhagia?
Tranexamic acid - decease blood loss by 50%
Mefanamic acid= analgesia
COCP- regulate cycle
IUD- can cause irregularity for 9 months then a lot of women stop having periods
Danazol- acne, weight gain, and voice changes (androgen excess)
Differentials for heavy and irregular periods?
- dysfunctional uterine bleed
- endometrial pathology
- Climateric
- Fibroids or adenomyosis
- ovarian pathology
Annovular dysfunctional uterine bleeding causation:
high unopposed oestrogen levels
What investigations would be most helpful in a woman presenting with heavy and irregular periods?
FBC- iron def. anaemia
FSH- (folicular stimulating hormone) check failure of ovarian function and also check beta hCG
USS- to exclude uterine and ovarian pathology. Endometrial thickness indicates endometrial pathology.
Outpatient hysteroscopy
Outpatient endometrial biopsy- carcinoma of the endometrium (women over 40)
US pathology in a endometrial cancer over 40
endometrial thickness less than 4 mm very low risk
Bleeding after vaginal intercourse differentials
- cervical ectropion
- cervical polyp
- cervicitis
- cervical carcinoma
risk factors for cervical ectropion
pill. pregnancy, puberty
investigations for intercourse bleeding after or during
cervical screening- obtain last smear
vaginal or cervical swabs fro microscopy and culture- only if infection suspected or if vaginal discharge
colposcopy and cervical biopsies= suspicion of malignancy or if cervical smear is abnormal
ovarian tumour modified risk of malignancy score
Ux Mx CA125
Ultrasound- multilocular cyst, solid area, evidence of mets ascites or bilateral lesions
M- menopausal status 1 premenopausal and 3 postmenopausal
CA125
low less than 25
moderate 25-250
high greater than 250
differential for pelvic mass
bladder tumour
intestinal tumour
diverticular disease
IBD
Tumour markers to consider in suspected ovarian cancer in less than 40 year old
AFP, hCG, LDH, inhibin, oestradiol
different types of benign ovarian Ca
non-neoplastic- functional: follicular cysts (less than 3 cm) pathological: PCOS, theca leutin, ovarian oedema
benign neoplastic- epithelial- serous, mucinous, brenner tumours
benign germ cell tumours- teratoma or dermoid cyst (may contain teeth can cause chemical peritonitis)
sex cord stromal tumours- sertoli leydig (virilization) lipoma
cervical cancer screening criteria
sexually active women 25-64
three yearly for women 25-50 year old if normal 5 yearly till 64
three yearly identifies 95% of all abnormalities
Management of abnormal smear tests- inflammatory
6% CIN I-II repeat un 6 months (if same result for 3 times- colposcopy)
Management of abnormal pap smear - borderline nuclear changes
20-30% CIN II-III if high risk due to HPV pos. colposcopy repeat in three years if negative
mild dyskaryosis - abnormal smear management
30% CIN II-III HPV pos- colposcopy if negative then smear in three years
moderate dyskaryosis - mgx of abnormal smears
50-75% CIN II-III refer to colposcopy
severe dyskaryosis
80-90% CIN II-III refer colposcopy
abnormal smear- invasion
50% invasion refer to colposcopy
abnormal glandular cells - abnormal smear
adenocarcinoma of the cervix- refer to colposcopy
