Q

What causes PID

A 
Chlamydia trachomatis (14–35% of cases) 
Neisseria gonorrhoeae (2–3% of cases) 
Mycoplasma genitalium

Organisms in normal vaginal flora (such as anaerobes, Gardnerella vaginalis, Haemophilus influenzae, enteric Gram-negative rods, and Streptococcus agalactiae) have also been implicated.

Q

How is the RMI calculated

A

ultrasound score x menopausal score x CA 125 level in U/mL.

The ultrasound score is the number of the following findings on scan: multilocular cyst, solid areas, bilateral lesions, ascites, intra-abdominal metastases. (0 = no abnormalities, 1 = one abnormality, 3 = two or more)

menopausal score is where 1 = premenopausal and 3 = postmenopausal).

32
How is menopause defined
12 months of amenorrhoea due to the loss of ovarian follicular activity
33
What is premature menopause
menopause occurring before the age of 40 years
34
What is the perimenopause
the period of change leading up to the last period.
35
What is early menopause
menopause between 40-45 years.
36
State the hormonal changes that occur in the menopause
reduced sensitivity of the ovary to circulating FSH and LH - due to reduction in follicle numbers. leads to reduction in oestrogen secretion leads to increased levels of FSH and LH The decrease in developing follicles also reduces the amount of inhibin released causing an enhanced rise of FSH.
37
What are the key symptoms of the perimenopause
``` irregular menstrual bleeding hot flushes - affect the face, head, neck and chest and last for a few minutes depression and mood change joint and muscle aches and pains vaginal discomfort and dryness, dyspareunia Loss of libido recurrent lower urinary tract infection. sleep disturbance ```
38
Why does amenorrheoa occur in the menopause
Estradiol production, which occurs in the granulosa and thecal cells surrounding the oocyte, becomes insufficient to stimulate the endometrium, and amenorrhoea occurs.
39
What causes the urogenital problems associated with menopause
loss of the trophic effect of oestrogen. there is atrophy of the vagina, thinning of vaginal walls and dryness
40
What causes the sleep disturbance in menopause
hot flushes and night sweats may also be due to mood disorders
41
What investigations are needed in menopause
clinical diagnosis! only done in premature ovarian failure; FSH to exclude other diagnoses: TFT Blood glucose A pelvic scan - may be considered for those women with atypical symptoms
42
How does the menopause affect bone metabolism
Oestrogen protects bone mass and density through reducing the activity of oesteoclasts. Decreased oestrogen leads to an increase in bone reabsorption leads to loss of bone density and increased frequency in fractures e
43
How does the menopause affect cardiovascular health
Oestrogen offers a protective effect against heart disease. It is thought that oestrogen reduces levels of LDL cholesterol whilst raising HDL cholesterol. After the menopause women experience the same frequency of cardiovascular disease as men.
44
What are the management options for the menopause
HRT non hormonal lifestyle
45
Give some lifestyle interventions for the management of symptomatic menopause
Hot flushes and night sweats — regular exercise, weight loss, wearing lighter clothing, sleeping in a cooler room, reducing stress, and avoiding possible triggers (such as spicy foods, caffeine, smoking, and alcohol). Sleep disturbances — avoiding exercise late in the day and maintaining a regular bedtime. Mood and anxiety disturbances — adequate sleep, regular physical activity, and relaxation exercises. Cognitive symptoms — exercise and good sleep hygiene.
46
Give some non-hormonal interventions for the management of symptomatic menopause
For vasomotor symptoms, consider a 2-week trial of fluoxetine (20 mg daily), citalopram (20 mg daily), or venlafaxine (37.5 mg twice a day). (off label) For vaginal dryness, prescribe a vaginal lubricant or moisturizer, such as Replens MD®. For psychological symptoms consider self-help groups, cognitive behavioural therapy (CBT), or antidepressants.
47
Which symptoms of menopause is HRT effective in treating
Vasomotor symptoms (hot flushes/night sweats). Mood swings. Vaginal and bladder symptoms.
48
Which women should be prescribed combined or oestrogen only HRT
In woman with a uterus - combined (oestradiol plus progestogen) HRT without a uterus - oestrogen-only preparation.
49
How can urogenital symptoms of menopause be managed with HRT
if urogenital atrophy (including those already using systemic HRT) - low-dose vaginal oestrogen. if vaginal dryness - moisturisers and lubricants can be used alone or in addition to vaginal oestrogen.
50
What are the risks of HRT
VTE - more so for oral than transdermal Coronary heart disease (CHD) and stroke -combined associated with small increase in risk Breast cancer - combined increases risk Endometrial cancer - oestrogen-only increases the risk of endometrial cancer in women with a uterus.
51
What are the benefits of HRT
``` reduction in vasomotor symptoms improvement in QOL improvement in mood changes improvement of urogenital symptoms reduction in osteroporosis risk` improvement in muscle mass and strength ```
52
How long is contraception required for after the menopause
Women who menopause under the age of 50 require contraception for at least 2 years after their last menstrual period. Those over the age of 50 require only 1 year of contraception.
53
What does cervical screening look for?
Liquid based cytology (LBC) to detect early abnormalities of the cervix, which if untreated could lead to cancer of the cervix. - abnormalities in the appearance of the nucleus and other aspects of cell morphology (dyskaryosis)
54
Who is screened for cervical cancer
First invitation for screening at age 25 Routine recall three-yearly recall between ages 25-49, then five-yearly recall until aged 65. Women over the age of 65 are only screened if they have not been screened since the age of 50 or have had recent abnormal tests.
55
How is the smear test carried out?
A speculum made from disposable plastic inserted vaginally to view the squamocolumnar junction of the cervix. A brush is rotated against the squamocolumnar junction (usually in the cervical canal). Brush top broken off into preservative or rinsed in preservative. Sent off for testing
56
What can be the histological result of cervical smear test
Negative - . Endocervical cells with normal nuclei are seen. Inadequate Borderline - Cells are seen with abnormal nuclei, but the pathologist cannot say for certain that they are indicative of dyskaryosis Mild dyskaryosis -usually equates to CIN 1. Cancer is very unlikely. Moderate dyskaryosis - usually equates to CIN 2 a pre-cancerous condition with an intermediate probability of developing into cancer. Severe dyskaryosis - equates to CIN 3. It is at the higher risk end of the cancer spectrum. Glandular neoplasia - suggestive of adenocarcinoma in situ, adenocarcinoma of the cervix, endometrial adenocarcinoma, or adenocarcinoma of an organ outside the uterus.
57
What can cause a cervical smear to come back as inadequate
insufficient or unsuitable material sampled (vaginal cells, endocervical cells, insufficient cells) unlabelled specimens inadequate fixation/poor spreading of the material on the slide in the laboratory.
58
What should be done if the smear comes back inadequate
Repeat sample as soon as possible If persistent (three inadequate samples), advise assessment by colposcopy.
59
What should be done if the smear comes back borderline or mild dyskaryosis
tested the sample for HPV If HPV is negative, women are returned to normal recall. If the HPV test is inadequate or unreliable, they are advised to have a repeat smear/HPV test in six months time. If HPV is positive, women are referred for colposcopy within 6 weeks
60
What should be done if the smear comes back moderate or severe dyskaryosis
refer for colposcopy within 2 weeks
61
What happens at colposcopy
Look for any abnormal changes in the cervix which may indicate CIN or the presence of cancer. Apply acetic acid is applied to the cervix, abnormal areas (such as CIN) tend to turn white (sometimes referred to as acetowhite). May take a biopsy to confirm the diagnosis.
62
What types of cervical cancer are there
Squamous cell carcinoma - more common | Cervical adenocarcinoma
63
What causes cervical cancer
HPV16 and HPV18 are responsible for about 75% of cervical cancers. integration of viral DNA into the host genome, interference of HPV E6 and E7 proteins with the normal cell regulatory functions
64
How long between infection with HPV and cervical cancer
10 years at least
65
What are the risk factors for HPV
Heterosexual women. Women with multiple sexual partners, or partners of promiscuous males. Smoking. Lower social class. Immunosuppression - eg, HIV and post-transplant. There is a slight increase in risk with use of a combined oral contraceptive. Non-attendance at the cervical screening programme
66
What are the symptoms of cervical cancer
asymptomatic - picked up on screening! ``` IMB PCB PMB Blood-stained vaginal discharge. Mucoid, or purulent vaginal discharge. Pelvic pain/dyspareunia. ```
67
What is seen on examination in cervical cancer
The cervix may appear inflamed or friable and bleed on contact visible ulcerating or fungating lesion foul-smelling serosanguineous vaginal discharge.
68
Give some differentials for cervical cancer
``` Cervicitis. Cervical erosion (ectropion). PID Endometrial cancer. Side-effects of intrauterine contraceptive device (IUCD) use. Endometrial hyperplasia. Fibroids. Atrophic vaginitis. ```
69
What is the difference between CIN and invasive cervical cancer
CIN does not breach the basement membrane invasive breaches the basement membrane
70
What are the subclassifications within CIN
CIN I: disease confined to the lower third of the epithelium. CIN II: disease confined to the lower and middle thirds of the epithelium. CIN III: affecting the full thickness of the epidermis.
71
What is the difference between microinvasive and invasive cervical cancer
micro-invasive carcinoma = the deepest invasive element is <5 mm from the surface of the epithelium invasive = extends beyond 5 mm or is wider than 7 mm
72
What investigations should be done in suspected cervical cancer
FBC, U+E, LFTs endocervical swab - chlamydia colposcopy and core biopsy CXR and CT CAP for mets
73
How is cervical cancer managed
radical hysterectomy and lymphadenectomy | chemoradiation
74
What causes a pelvic prolapse
weakness of the supporting structures allows the pelvic organs to protrude within the vagina
75
What increases the risk of prolapse
``` prolonged labour, trauma from instrumental delivery, lack of postnatal pelvic floor exercise, obesity, chronic cough and constipation. Poor perineal repair ```
76
What is a cystocoele
the anterior wall of the vagina, and the bladder attached to it, bulge.
77
What symptoms can a cystocele cause
Residual urine within the cystocele may cause frequency and dysuria.
78
What is a rectocele
The lower posterior wall, which is attached to rectum, may bulge through weak levator ani.
79
What might a woman with a rectocele need to do to aid defecation
reduce herniation prior to defecation by putting a finger in the vagina, or pressing on the perineum.
80
What is an enterocele
Bulges of the upper posterior vaginal wall may contain loops of intestine from the pouch of Douglas.
81
What is a uterine prolapse
Protrusion of the uterus downwards into the vagina, taking with it the cervix and upper vagina.
82
What is the difference between first, second and third degree prolapses
First degree: The lowest part of the prolapse descends halfway down the vaginal axis to the introitus. Second degree: The lowest part of the prolapse extends to the level of the introitus, and through the introitus on straining. Third degree: The lowest part of the prolapse extends through the introitus and outside the vagina.
83
What are the symptoms of prolapse
``` Dragging sensation, discomfort, feeling of a lump ‘coming down,’ dyspareunia, backache. ``` With cystocele, urinary urgency and frequency, incomplete bladder emptying, urinary retention if the urethra is kinked. With rectocele, constipation and difficulty with defecation.
84
How is a prolapse examined
Bimanual to exclude pelvic masses. Examine for prolapse with the woman in left lateral position using a Sims speculum. Inspect anterior and posterior walls for atrophy and descent. If no obvious prolapse, ask the woman to strain or stand.
85
How is prolapse managed
Conservative: lose weight, stop smoking, and stop straining. Improve muscle tone with exercises or physiotherapy. Pessaries - should be changed every 6 months and if the woman is post-menopausal, topical oestrogen is useful to prevent vaginal erosion. Surgery: Repair operations excise redundant tissue and strengthen supports, but may reduce vaginal width.
86
How do pessaries for prolapse work?
Placed between the posterior aspect of the symphysis pubis and posterior fornix of the vagina. Most are ring shaped.
87
When is surgery for pevic organ prolapse useful?
if symptoms are severe, the woman is sexually active, and pessaries have failed
88
What are the different surgical options for prolapse
vaginal vault prolapse = sacrocolpoplexy to suspen the vaginal apex to the sacral promontory. cystocele = Anterior colporrhaphy to repair vaginal wall or colposuspension rectocele: posterior colporrhaphy uterine prolapse: hysterectomy, sacrohysteropexy
