2 Definition of normal menstruation Cycle Length Cycle predictability Duration Volume of blood flow

3 Cycle Length Number of days from day 1 of one menstrual period to day 1 of the next menstrual period Normal cycle length from 22 to 35 days Later in the reproductive year, cycle length tends to be come shorter

4 Duration of menstrual Flow NICE guidelines Normal duration is between 3-8 days

5 4 Key menstrual dimension Regularity irregular, normal or absent Frequency- frequent, normal or infrequent Duration- prolonged, normal or shortened Volume- heavy, normal or light

6 Regularity Regular - +/- 2 to 20 days Abnormality 1- irregular variation > 20 days Abnormality 2 - absent

7 Frequency Normal days Abnormality 1- Frequent <24 days Abnormality 2 Infrequent >38 days

8 Duration Normal days Abnormality 1 Prolonged >8 days Abnormality 2 Shortened <4.5 days

9 Volume Normal Abnormality 1 Heavy Abnormality 2 - Light

10 Intermenstrual Bleeding Bleeding that occurs between cyclically normal menstrual bleeding May be related to contact, or spontaneous, maybe cyclical or occurs at random times between periods

11 Breakthrough Bleeding Unscheduled uterine bleeding that occurs in association with the use of gonadal steroids or other agents designed to suppress endocrine regulation of the endometrial function

12 Acute and Chronic Abnormal Uterine Bleeding Chronic AUB- bleeding that is abnormal in volume, regularity and/or timing which has been present for at least 3 months Acute AUB is an episode of sufficient volume to require urgent or emergency intervention

13 Classification of AUB Uterine Polyp Adenomyosis Fibroids Malignancy /hyperplasia Coagulopathy Ovulatory dysfunction Endometrial Iatrogenic

14 Chronic AUB If cyclical predictability present HMB is due to conditions such as adenomyosis, fibroids, coagulopathy and endometrial pathology Intermenstrual bleeding is normally due to polyp

15 Chronic AUB Totally unpredictable bleeding outside the context of regular and predictable periods are associated with ovulatory disturbances It might be an indication of endometrial hyperplasia or malignancy

16 Investigation of AUB History- accurate history including normal menstrual pattern, timing, volume and associated symptoms? Affecting quality of life

17 History Cyclical predictable What is complaint? Intermenstrual bleeding -?polyp Heavy MB-?adenomyosis, fibriods, coagulopathy, endometrial

18 History Unpredictable bleeding HMB & or unpredictable AUB Cause? AUB-O or AUB- M

19 Physical Examination Look for sudden weight loss, obesity, bruising, endocrine problems, anaemia Inspection of perineum to exclude local causes Speculum examination -?cervical polpy, ectropion, cervical tumour, cervicitis Bimanual examination- pelvic mass, fibroid, adenomyosis

20 Investigation Measurement of Hb/ serum ferritin Coagulation studies Thyroid Function Luteal phase progesterone

21 Evaluation of Uterus Histological evaluation endometrial biopsy Ultrasound Hysteroscopy

22 Ultrasound Typically endometrial thickness is measured and reported as a sum of two adjacent layers of endometrium- called the endometrial echo complex Typically the EEC is 4mm in the menstrual phase up to 12mm in the the luteal phase

23 Ultrasound Thickness can vary in the presence of ovulatory disorders? What is the upper threshold One study suggest that as long as the endometrial thickness is 12mm or less, there is low incidence of hyperplasia or neoplasia

24 Management of HMB Mirena IUS Tranexamic acid-1g qds COC- Qlaira Progesterone noretheristone, depo-provera Danazol mg/day for patient with ITP

25 Mirena IUS Reduction of 81.6% in blood loss at 3 months and 95.8% at 12 months No difference between Mirena IUS and endometrial ablation Benefit in dysmenorrhoea related to adenomyosis or endometriosis PMS/ HRT protection

26 Tranexamic Acid When used 1 g qds for 4 days is associated with a 40-60% reduction in bleeding volume It does not increase risk of thromboembolic disease even when used in women at high risk Safe to use

27 Cyclooxygenese inhibiotrs In women with menorrhagia, mean reduction in blood flow was 20% ( 5 of the 7 RCT) Dose- start on first day of period for 5 days or until period stops Mefenamic acid- 500mg tds Ibuprofen md/day Benefit for accompanying dysmenorrhoea

28 Progesterone Cyclical fashion norethisterone 5mg tds from day 5 to day 26 reduced blood loss by 87% Continuous administration no clinical trials /evidence NET- 5-15mg/day MPA mg/day Depo- provera

29 Combined OCP A single study showed menstrual blood flow reduction by 50% Another study showed 80% improvement compared with 26% receiving placebo Qlaira- NICE approved for HMB showing blood reduction up to 87%

30 Management of AUB in primary care Define possible cause Investigation according to differential diagnosis Ultrasound scan, fbc, etc

31 Management of AUB in primary care How is AUB affecting QOL? What are patients expectations? Discuss medical options- explain that Mirena IUS as effective as endometrial ablation. Hysterectomy is cure but potential morbidity/mortality

32 Management of AUB If medical options accepted, plan to improvement of symptoms within 3-6 months If no success, referral into secondary care

33 Surgical Treatment Endometrial ablation Hysterectomy

34 Acute AUB Modestly heavy to excessive bleeding associated with hypovolumeic shock If patient unstable- refer into hospital If stable- consider management in primary care

35 Investigation Exclude pregnancy History and physical examination exclude trauma, molar pregnancy, degenerating fibroid polyp etc Medical treatment as out patients

36 Management Option 1 Oral progestins- MPA mgs daily until bleeding stops for at least 2 days Then 20-40mg/day for 3-6 weeks 25% patients stop bleeding within 24 hours Remainder ceased bleeding by the 4 th day

37 Management Option 2 Another regimen is 60mgs of MPA in three divided doses for the first week Then continue with 20mgs/day for 3 weeks

38 Management -Option 3 Norethisterone 5-15mg daily until bleeding stops for at least 2 days Followed by 10mg daily for 3 weeks.

39 Management- Option 4 Combined oral contraceptive pill Monophasic pill oestrogen 35ug such as Norinyl Three to four times a day until bleeding stops for at least 2 day Then daily for 3-6 weeks eliminating placebo pills

40 Management Once bleeding has stopped, patient needs investigated Ultrasound scan and biopsy Management according to findings

42 Pelvic Pain Chronic pelvic pain is defined as pain that occurs below the umbilicus (belly button) that lasts for at least six months. It may or may not be associated with menstrual periods. Chronic pelvic pain is not a disease, rather, it is a symptom that can be caused by several different conditions.

43 Endometriosis Endometriosis - a condition in which endometrial tissue is also present outside of the uterus. Some women with endometriosis have no symptoms, while others experience marked discomfort and pain and may have problems with fertilty

44 Pelvic Inflammatory Disease Pelvic inflammatory disease is an infection caused by a sexually transmitted organism. Occasionally, it is caused by a previous ruptured appendix or scarring resulting from previous pelvic surgery. Pelvic inflammatory disease can cause pain, abnormal uterine bleeding, and symptoms of infections

45 Irritable Bowel syndrome is a gastrointestinal condition characterized by chronic abdominal pain and altered bowel habits (such as loose stools, more frequent bowel movements with onset of pain, and pain relieved by defecation) in the absence of any specific cause

46 Diverticulitis A diverticulum is a sac-like protrusion that sometimes forms in the muscular wall of the colon (or intestine). Diverticulitis occurs when diverticula become inflamed. This usually causes abdominal pain; nausea and vomiting, constipation, diarrhea, and urinary symptoms can also occur

47 Painful Bladder Syndrome the term given to pain in the tissues in the bladder and surrounding nerves and muscles that is not caused by infection. Symptoms include the need to urinate frequently (frequency) and a feeling of urgently needing to urinate (urgency). Some women with painful bladder syndrome have lower abdominal or pelvic pain in addition to urinary tract symptoms.

48 Pelvic Floor Pain The muscles of the pelvic floor can sometimes become shortened, tight and tender; this is called pelvic floor dysfunction. The pelvic floor includes muscles that attach to the pelvic bones and sacrum (lower part of the spine). Normally, these muscles function to support the hips and pelvic organs. It is not clear why this problem develops.

49 Pelvic Floor Pain Symptoms may include pelvic pain, pain with urination, constipation, pain with intercourse, or frequent/urgent urination. Pelvic floor dysfunction can be diagnosed by a clinician feeling the muscles in the vagina and/or rectum; muscles that feel tight, tender, or band-like indicate that pelvic floor dysfunction could be contributing to pelvic pain.

50 Abdominal myofascial pain Pain can originate from the muscles of the abdominal wall due to myofascial pain. This problem usually has small localised areas of abdominal tenderness of the abdominal muscles that are called trigger points. AMP is diagnosed by the clinician examining the abdominal muscles for trigger points- often tightening of these muscles while they examined causes increased pain and assist in diagnosis

51 Fibromylgia chronic pain disorders that affect connective tissue structures, including muscles, ligaments and tendons. It is characterized by widespread muscle pain (or "myalgia") and tenderness in certain areas of the body. Women with fibromyalgia may also experience fatigue, sleep disturbances, headaches, and mood disturbances such as depression and anxiety.

52 Investigation A thorough history and a physical examination of the abdomen and pelvis are essential components of the work-up for women with pelvic pain. In particular, the examination should include the lower back, abdomen, hips, and pelvis (internal examination).

53 Investigation Laboratory tests, including a white blood cell count, urine analysis, tests for sexually transmitted infections, and a pregnancy test may be recommended, depending upon the results of the physical examination. Laparoscopy and cystoscopy

54 Role of ultrasound scan Pelvic scan is accurate in detecting pelvic masses, including ovarian cysts (sometimes caused by ovarian endometriosis) and uterine fibroids. However, ultrasound is not helpful in the diagnosis of irritable bowel syndrome, diverticulitis, or painful bladder syndrome

55 Management of Chronic PP 1 st option is to prescribe sequential drug treatments for disorders that re the most likely cause of patient s pain eg endometriosis, infection 2 nd option - A different approach is to use intensive diagnostic testing in an attempt to identify specific cause of pain before starting treatment. This might involve costly laboratory, imaging tests and exploratory surgery 3 rd option is treatment directed at pain rather than at a specific diagnosis-nsaid, antidepressants, anticonvulsants

56 Physical Therapy Pelvic floor physical therapy can help in patients with myofascial pain and pelvic floor pain. This type of physical therapy aims to release the tightness in these muscles in the abdomen, vagina, hips thigh and lower back Physical therapy needs specialist skills- trained physiotherapist

57 Pain management clinic If conventional treatment has been unsuccessful, consider referral to pain clinic Uses multiple treatment modalities Acupuncture Biofeedback and relaxation therapy Nerve stimulation Injection of tender sites with local anesthetise Prescribe opiates

58 Symptoms of endometriosis severe dysmenorrhoea deep dyspareunia chronic pelvic pain ovulation pain

59 Symptoms of endometriosis cyclical or perimenstrual symptoms, such as bowel or bladder, with or without abnormal bleeding or pain infertility chronic fatigue dyschezia (pain on defaecation).

60 Examination Deeply infiltrating nodules are most reliably detected when clinical examination is performed during menstruation Adenomyosis- tender smooth uterus which is mobile

61 Diagnosis If a woman wants pain symptoms suggestive of endometriosis to be treated without a definitive diagnosis, a therapeutic trial of a hormonal drug to reduce menstrual flow is appropriate. Gold standard - laparoscopy

62 Endometriosis Mirena IUS OCP Depo-Provera Danazol GnRh Angonist- prostap/zoladex Treatment can be undertaken without diagnosis

63 Medical Treatment There is inconclusive evidence to show whether NSAIDs (specifically naproxen) are effective in managing pain caused by endometriosis. Suppression of ovarian function for 6 months reduces endometriosis-associated pain. Symptom recurrence is common following medical treatment of endometriosis.

64 Mirena IUS A systematic review identified two randomised controlled trials and three prospective observational studies, all involving small numbers and a heterogeneous group of patient. Nevertheless, the evidence suggests that the LNG-IUS reduces endometriosis-associated pain with symptom control maintained over 3 years

65 Medical Treatment Duration of therapy should be determined by the choice of drug, response to treatment and adverse effect profile. If after 3-6 months, no response, referral into hospital for laparoscopy

66 Surgical Management Ideal practice is to diagnose and remove endometriosis surgically Ablation of endometriotic lesions reduces endometriosis-associated pain Endometriosis associated pain can be reduced by removing the entire lesions in severe and deeply infiltrating disease.

67 Management of Pelvic Pain Exclude infections-if infection screen positive, treat and reassess Ultrasound scan to exclude ovarian cyst, fibroids, endometrioma etc If symptoms suggestive of endometriosis, start treatment without the need for diagnosis If after 3-6 months, no improvement to refer for laparoscopy

68 Painful Bladder syndrome Negative urine culture Referral to continence team for bladder retraining Urinary frequency and urgency, treat with anticholinergic Bladder diary to include food diary- patient to avoid acidic foods such as tomatoes, caffeine, pineapples etc

69 Medical Treatment of PBS Hydroxyzine 10mg nocte increasing according to symptoms Cimetidine 400mgs bd Amitryptyline/ nortriptyline Gabapentin Pregabalin

70 Painful Bladder Syndrome If symptoms not improved, referral for cystoscopy with cystodistention Bladder instillations with cystistat, uracyst etc Elmiron (Pentosan Polysulphate) Botox, bladder diversion and cystectomy

72 Indication for HRT acute menopausal symptoms flushes, night sweats mood change poor sleep, tiredness memory disturbance quality of life urogenital symptoms vaginal dryness dyspareunia reduced libido premature menopause

73 Urogenital Atrophy Affects vagina and bladder Underreported and undertreated Vaginal dryness, dyspareunia, reduced libido 2/3 women by the age of 75

74 Under reporting 20-25% with symptoms seek help One survey- 78% feeling active sex life important 59% hide symptoms from partner

75 Under treating 25% with genito-urinary symptoms who seek help receive treatment

76 Premature Menopause Age < 40 years If untreated there is increased risk of CHD Osteoporosis Dementia Usual Advice to replace hormones to age 50 years. These years not counted in risk assessment

77 Is HRT Safe? Does it cause? Heart attacks/stroke Breast cancer Ovarian/endometrial cancer Thromboembolism What do we tell patients???

78 Communicating risk Relative Risk (RR) takes no account of incidence Absolute risk estimates the number of extra cases in a population

79 HRT & CHD risk WHI % increase (RR1.29) 7extra cases per 10,000 women years Years since menopause <10yrs yrs >20 yrs Age group

80 What to tell patients about heart attacks HRT use within 10 years of menopause has not been shown to increase risk for heart attacks

81 HRT & Stroke risk WHI % increase (RR1.41) 7extra cases per 10,000 women years oestrogen + progestogen oestrogen alone yrs yrs yrs 13 14

82 What to tell patient about strokes Both E and E+P increase risk of stroke Risk increases with age Smoking, obesity, hypertension increase risk Approx 1 extra stroke in 1000 users in 5 years

83 HRT and Breast cancer risk oestrogen + progestogen oestrogen alone yrs yrs yrs + 7-1

84 What to tell patients about breast cancer E+P increases risk Risk is duration dependent Overall risk is in years group is 3 extra cases in 1000 women in 5 year use No apparent risk < 5 years No apparent risk E alone < 7 years

85 HRT and endometrial cancer May increase 2 folds in sequential therapy > 5 years Reduced risk in CCHRT (not tibolone) Endometrial hyperplasia with vaginal premarin

86 HRT and ovarian cancer WHI- no risk MWS- 1 extra ovarian cancer in 2,500 user over 5 years with 1 extra death in 3,300 users over 5 years

87 HRT and VTE Risk of VTE increases with age, obesity etc Background risk years is 1 per 1000 per year and 2 in HRT increases risk 2-3 folds Highest risk in first year of use Transdermal avoids first pass? Safer

88 MWS in Jan 2012 Cancer detected within few months of study would have already been present and these were not excluded in analysis Study participants were from breast screening programme. This invitation could have led to higher number of cancers being detected (detection bias)

89 MWS in Jan 2012 Even a small detection bias, accounting for extra cases a year in HRT users would have invalidated the findings The average time from recruitment to detection of breast cancer of 1.2 to 1.7 years and the likelihood of fatal cancer being 22% higher amongst HRT users within this short time frame was biologically implausible

90 MWS in Jan 2012 Recent critique of MWS with its flaws limited the ability to establish a casual association (if one exists) between HRT and breast cancer A recent WHI trial also has suggested failure to establish causality and the fall of breast cancer rates in UK predated the publication of MWS

91 Missing points Menopausal symptoms are debilitating. Majority use HRT for valid reasons having weighed up pros and cons HRT discussed as if it were one entity with identical benefits and risk outcomes. Studies were done 20 years ago and now preparations are lower dose often transdermal and identical to endogenous hormones

92 Future? Pilot studies using lower dose endogenous type hormones in younger women are due to report in the near future and are expected to show favourable outcomes

93 Take Home Message Use HRT for a few years in symptomatic women in their early 50s Reassess needs every year and aim to stop treatment where possible after 5 year use Patients with premature ovarian failure should continue until, aged 50 years

94 Case 1 A 36 year old Para 2, comes to you with a history of heavy periods. Her partner has had a vasectomy. Discuss her management
