Q

What happens to the endometrium in the first half of the menstrual cycle?

Q

What happens to the endometrium in the second half of the menstrual cycle?

A

The glands swell and blood supply increases - luteal/secretory phase - under influence of progesterone - then progesterone levels drop and secretory endometrium disintegrates

Q

What is the aetiology of fibroids?

A

Fibroid growth is oestrogen and probably progesterone dependent
During pregnancy, fibroids equally likely to grow, shrink or show no change
Fibroids regress after menopause because of reduction in circulating oestrogen

Q

Investigations with fibroids

A

US
MRI or laparoscopy might be needed to distinguish fibroid from ovarian mass
Hb - anaemia due to bleeding or high as fibroids can secrete erythropoietin

Q

When do no treatment for fibroids?

A

Asymptomatic if small or slow-growing then no treatment and no monitoring needed either as risk of malignancy is small
Larger need monitoring because remote possibility of malignancy

Q

Medical treatment of fibroids

A

Tranxamic acid, NSAIDs or progestogens often ineffective for menorrhagia due to fibroids but worth trying first
GnRH agonists for 6 months or with “add-back” HRT to prevent side effects and bone density problems
Often used to shrink before surgery
GnRH agonists not good for trying to conceive because decreases ovulation
Also fibroids return to previous size after stopping GnRH

What is endometritis?
Infection confined to the cavity of the uterus alone | Spread to pelvis is common if untreated

Rare!! 150 cases in UK per year
64
What is the blood supply to the cervix?
Upper vaginal branches and uterine artery
65
Where do cervix lymphatics drain to?
Obturator and internal/external iliac nodes - then to the common iliac and para-aortic nodes
66
What is cervical ectropion?
When the columnar epithelium of the endocervix is visible as a red area around the os of the cervix
67
What causes cervical ectropion?
Due to eversion of cervix - normal finding in young women, esp. taking pill or who are pregnant
68
Symptoms of cervical ectropion
Normally asymptomatic | Can cause vaginal discharge or PCB
69
Treatment of symptomatic cervical ectropion
Freezing with cryotherapy - but only once smear has been done and carcinoma excluded
70
Risk associated with cervical ectropion?
Exposed columnar epithelium is prone to infection
71
Details of acute cervicitis
Rare - often results from STIs Ulceration and infection occasionally found Severe cases can have prolapse
72
Details of chronic cervicitis?
Chronic inflammation or infection often of an ectropion Common cause of vaginal discharge Cryotherapy is used with or without antibiotics
73
What is cervical intraepithelial neoplasia (CIN) also called?
Cervical dysplasia
74
What is CIN?
Presence of atypical cells within squamous epithelium
75
What is the grading for CIN?
CIN 1 - mild dysplasia - cells only found in lower 1/3 of epithelium CIN 2 - moderate dysplasia - cels only found in lower 2/3 of epithelium CIN 3 - severe dysplasia - cells occupy full thickness of epithelium
76
What is CIN 3?
Cervical carcinoma in situ - cells are the same as those found in malignant lesions but there is no invasion
77
How does CIN 3 or carcinoma in situ become cervical malignancy?
Invasion of the cells through the basement membrane
78
Prognosis of untreated CIN II/III?
1/3 of women will develop cervical cancer over next 10 years
79
Prognosis of CIN I?
Least malignant potential - CIN I can progress to CIN II/III but usually regresses spontaneously
80
Peak incidence of CIN III
90% are under 45 years | Peak incidence in those 25-29years
81
Most important risk factor for CIN
HPV which is sexually transmitted - therefore number of sexual partners
82
What strains of HPV does the vaccine target?
Types 16 and 18 - responsible for 75% of cervical cancers in the UK
83
What are other risk factors for CIN?
Oral contraceptive use Smoking Immunocompromised patients are also at increased risk and have increased risk of early progression to malignancy
84
Symptoms of CIN
CIN causes no symptoms and is not visible on the cervix - therefore done with cervical smears
85
Age and frequency of cervical smears in UK
25 (or after first intercourse) then repeated every 3 years until age 49 From 50-64 every 5 years
86
Management of low-grade cellular abnormalities found on smear test
eg. dyskaryosis or borderline changes - Sample tested for HPV - if high-risk HPV type then colposcopy If low-risk HPV then back to routine smear tests
87
Management of abnormal columnar cells on smear
Colposcopy (speculum and operating microscope) with biopsy
88
Management of CIN II and III
Transformation zone is excised with cutting diathermy - large loop excision of transformation zone (LLETZ)
89
Consequence of LLETZ
May have postoperative haemorrhage rarely | Risk of subsequent preterm delivery is slightly higher
90
Peak incidences of cervical carcinoma
During 30s and during 80s but majority of cases are in women aged 25-49
91
Risk factors for cervical carcinoma
Same as for CIN - HPV, sexual partners | Not familial
92
What is occult cervical carcinoma?
When there are no symptoms but diagnosis is made by biopsy or LLETZ
