Gynaecology Flashcards
Definition of endometriosis
Presence of endometrial tissue outside the uterus
What is a chocolate cyst
ovarian endometrioma
frequency of endometriosis
5-10% women
Relative proportion types of cervical cancer
Squamous cell 80%
Adenocarcinoma 20%
Features of cervical cancer
Detected during screening
Abnormal vaginal bleeding:postcoital, intermenstrual or postmenopausal
Vaginal discharge
Risk factors for cervical cancwe
HPV , esp 16, 18 & 33
Smoking
HIV
Early first intervourse, many sexual partners
High parity
Low socioeconomic status
COCP
How does HPV cause cervical cancer
HPV 16 produces E6 oncogene inhibiting p53 tumour suppressor gene
HPV 18 produces E7 oncogene inhibiting Rb suppressor gene
Risks for endometrial cancer
Obesity
Nulliparity
Early menarche
Late menopause
Unopposed oestrogen
Diabetes mellitus
Tamoxifen
PCOS
Hereditary non-polyposis colorectal carcinoma
Features of endometrial cancer
postmenopausal blesding is classic. Usually initially slight and intermittent, then more heavy
Premenopausal bleeding = change in intermenstrual bleeding
Pain is not common
Vaginal discharge is unusual
Investigations for endometrial cancer
women >55 presenting with postmenopausal bleeding should be referred on suspectedcancer pathway
First line investigation is transvaginal ultrasound, if endometrial thickness <4mm then has high negative predictive value
Hysteroscopy with endometrial biopsy
Mmagement of endometrial cancer
localized disease is treated with total abdominal hysterectomy with bilateral salpingooopherectomy. If high risk may have post op radiotherapy
Progestogen therapy sometimes in frail elderly women not suitable for surgery
Risks for ovarian cancer
Family history: Mutations of BRCA1 or 2
Many ovulations: Early menarche, late menopause, nulliparity
Clinical features of ovarian cancer
abdominal distension and bloating
Abdominal and pelvic pain
Urinary symptoms, eg. urgency
Early satiety
Diarrhoea
investigations for ovarian cancer
ca125 (altho may be raised in endometriosis, menstruation, benign ovarian cysrs and other cinditions)
If raised, then urgent USS abdo and pelvis
Not for asymptomatic
Ultimately need diagnostic laparotomy
Ovarian cancer management and prognosis
Combo of surgery and platinum based chemo
85% have advanced disease at presentation
All stage 5 yr survival is 46%
Differential diagnosis for abnormal uterine bleed
(PALM CODEIN)
Polyp
Adenomyosis
Leiomyoma
Malignancy
Coagulation disorder
Ovulatory dysfunction
Endometrial
Infection/iatrogenic
Not yet known
Features of adenomyosis
Multiparous women at end of reproductive years
Dysmenorrhoea
Menorrhagia
Enlarged boggy uterus
Management of adenomyosis
GnRH agonists
Hysterectomy
Causes of primary amenorrhoea
Gonadal dysgenesis (eg Turner’s syndrome)
Testicular feminisation
Congenital malformations of genital tract
Functional hypothalmic amenorrhoea (eg 2ndary to anorexia)
Secondary causes of amenorrhoea
hypothalamic amenorrhoea (eg secondary stress, excessive exercise)
PCOS
Hyperprolactinaemia
Premature ovarian failure
Thyrotoxicosis
Sheehan’s syndrome
Asherman’s syndrome
Risk factors for STIs
Multiple partners (>2 in 6 months )
Recent partner change (last 3 months)
Non use of barrier contraceptives
STI or symptoms in partner
Other or previous STI
<25 and even more if <20
Urban area
Low socio economic status
Routine STI Ix in men
first pass urine for chlamydia and gonorrhoea
Syphilis serology
HIV test (with consent)
Additional STI Ix in Men if discharge/dysuria
gram stained urethral smear with or without culture for gonorrhoea
Additional STI Ix for MSM
Pharyngeal swab for gonorrhoea (NAAT)
Rectal sample (if appropriate) for chlamydia and gonorhoeA
Hep B screening if not vaccinated
Hep C screening according to risk
STI ix in women
posterior vaginal swab for trichomoniasis
Endocervical sample for chlamydia and gonorrhoea NAAT
Syphilis serology
HIV test with consent
Additional STI Ix if symptomatic
wet prep of vaginal secretions for trichomoniasis
Gram stain for candida and BV
culture of genital secretions for candida
Perinatal transmission of chlamydia
Leads to neonatal conjunctivitis in 30-50% of exposed babies, usually in 2nd week of life.
Less commonly, pneumonitis between 4 and 12 weeks of age
Symptoms of chlamydia (F)
up to 80% asymptomatic
Menstrual irregularities (IMB, PCB)
