Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

Understanding Risk Factors for Ectopic Pregnancy

Ectopic pregnancy is a serious condition where a fertilized egg implants outside of the uterus, usually in the fallopian tube. While there are several risk factors associated with ectopic pregnancy, some common misconceptions exist. Here are some important facts to keep in mind:

Methods of contraception, such as intrauterine devices (IUDs), do not increase the risk of ectopic pregnancy. However, IUDs can cause side effects such as irregular bleeding and pelvic pain.

The combined oral contraceptive pill can cause various side effects, but ectopic pregnancy is not one of them.

Subserosal fibroids and corpus luteal cysts can cause abdominal pain and other symptoms, but they do not increase the risk of ectopic pregnancy.

Previous miscarriage is not a risk factor for ectopic pregnancy, but it can increase the risk of future miscarriages.

It’s important to understand the true risk factors for ectopic pregnancy in order to make informed decisions about contraception and reproductive health. If you experience symptoms such as abdominal pain, vaginal bleeding, or shoulder pain, seek medical attention immediately as these could be signs of ectopic pregnancy.

TVUS is the recommended initial investigation for PMB, unless there are contraindications. This is because it provides the most accurate measurement of endometrial thickness, which is crucial in determining if the bleeding is due to endometrial cancer.

Understanding Postmenopausal Bleeding

Postmenopausal bleeding refers to vaginal bleeding that occurs after a woman has gone 12 months without a menstrual period. While most cases do not involve cancer, it is important to rule out this possibility in all women. The most common cause of postmenopausal bleeding is vaginal atrophy, which occurs due to a reduction in estrogen following menopause. Other causes include hormone replacement therapy, endometrial hyperplasia, endometrial cancer, cervical cancer, ovarian cancer, and vaginal cancer.

To investigate postmenopausal bleeding, women over the age of 55 should undergo an ultrasound within two weeks to check for endometrial cancer. If referred on a cancer pathway, a transvaginal ultrasound is the preferred method of investigation. Treatment options depend on the underlying cause of the bleeding. For vaginal atrophy, topical estrogen and lifestyle changes can help alleviate symptoms, while HRT may also be used. If the bleeding is due to a specific type of HRT, switching to a different preparation may be helpful. In cases of endometrial hyperplasia, dilation and curettage may be necessary to remove excess tissue.

Overall, it is important for women experiencing postmenopausal bleeding to seek medical attention and undergo appropriate testing to rule out any serious underlying conditions.

Hormones Involved in Pregnancy Testing

Pregnancy testing relies on the detection of specific hormones in the body. One such hormone is human chorionic gonadotropin (hCG), which is secreted by the syncytiotrophoblast of a developing embryo after implantation in the uterus. The unique subunit of hCG, β, is targeted by antibodies in blood and urine tests, allowing for early detection of pregnancy. Luteinising hormone (LH) and follicle-stimulating hormone (FSH) also play important roles in female reproductive function, but are not measured in over-the-counter pregnancy tests. Progesterone, while important in pregnancy, is not specific to it and therefore not useful in diagnosis. The hCG subunit α is shared with other hormones and is not specific to pregnancy testing.

The patient is likely suffering from endometriosis, which is the presence of endometrial tissue outside of the uterus. This condition can cause subfertility, chronic pelvic pain, dysmenorrhoea, and dyspareunia. It may also lead to an increase in serum CA-125 levels and the development of ovarian deposits known as chocolate cysts. Acute appendicitis and ovarian neoplasms are unlikely causes of the patient’s symptoms, while mittelschmerz only causes mid-cycle pain and does not explain the elevated CA-125 levels. Granulosa cell tumors of the ovary typically secrete inhibin and estrogen, making endometriosis a more likely diagnosis. Symptoms of ovarian cancer are often vague and include abdominal discomfort, bloating, back and pelvic pain, irregular menstruation, loss of appetite, fatigue, and weight loss. Risk factors for ovarian cancer include not having children, early first menstruation and last menopause, hormone replacement therapy, endometriosis, and the BRCA genes. In this age group, germ cell tumors are the most likely ovarian carcinoma.

If a patient presents with primary amenorrhoea and raised FSH/LH levels, it is important to consider the possibility of gonadal dysgenesis, such as Turner’s syndrome. This condition is characterized by the presence of only one X chromosome or a deletion of the short arm of one X chromosome, which can result in widely spaced nipples and other physical characteristics. In Turner’s syndrome, the lack of estrogen and progesterone production by the ovaries leads to an increase in FSH/LH levels as a compensatory mechanism. Therefore, an increase in FSH/LH levels is consistent with this diagnosis. Cyclical pain due to an imperforate hymen typically presents with secondary sexual characteristics, while increased prolactin levels are associated with galactosemia, and increased androgen levels are associated with polycystic ovarian syndrome. In the case described, a diagnosis of Turner’s syndrome is likely, and serum estrogen levels would not be expected to be elevated due to gonadal dysgenesis.

Understanding Amenorrhoea: Causes, Investigations, and Management

Amenorrhoea is a condition characterized by the absence of menstrual periods in women. It can be classified into two types: primary and secondary. Primary amenorrhoea occurs when menstruation fails to start by the age of 15 in girls with normal secondary sexual characteristics or by the age of 13 in girls without secondary sexual characteristics. On the other hand, secondary amenorrhoea is the cessation of menstruation for 3-6 months in women with previously normal and regular menses or 6-12 months in women with previous oligomenorrhoea.

There are various causes of amenorrhoea, including gonadal dysgenesis, testicular feminization, congenital malformations of the genital tract, functional hypothalamic amenorrhoea, congenital adrenal hyperplasia, imperforate hymen, hypothalamic amenorrhoea, polycystic ovarian syndrome, hyperprolactinemia, premature ovarian failure, Sheehan’s syndrome, Asherman’s syndrome, and thyrotoxicosis. To determine the underlying cause of amenorrhoea, initial investigations such as full blood count, urea & electrolytes, coeliac screen, thyroid function tests, gonadotrophins, prolactin, and androgen levels are necessary.

The management of amenorrhoea depends on the underlying cause. For primary amenorrhoea, it is important to investigate and treat any underlying cause. Women with primary ovarian insufficiency due to gonadal dysgenesis may benefit from hormone replacement therapy to prevent osteoporosis. For secondary amenorrhoea, it is important to exclude pregnancy, lactation, and menopause in women 40 years of age or older and treat the underlying cause accordingly. It is important to note that hypothyroidism may also cause amenorrhoea.

Treatment Options for Primary Dysmenorrhoea: A Guide for Healthcare Professionals

Primary dysmenorrhoea is a common condition that affects many women of reproductive age. When treating this condition, healthcare professionals have several options to consider. Here, we will discuss the most common treatments and their appropriateness for different patients.

Paracetamol is a suitable first-line treatment for patients with primary dysmenorrhoea who cannot take NSAIDs. If the patient does not wish to conceive, a hormonal contraceptive may also be considered as a first-line treatment.

Gabapentin is not recommended for the treatment of dysmenorrhoea, as it is primarily used for epilepsy and neuropathic pain.

Mefenamic acid and naproxen are both NSAIDs and are recommended as first-line treatments for primary dysmenorrhoea. However, they are contraindicated in patients with a history of asthma triggered by NSAID use.

Oral morphine is not typically used as a first-line treatment for dysmenorrhoea. If NSAIDs and paracetamol are not effective, transelectrical nerve stimulation (TENS) may be trialled. If none of these treatments are effective within 3-6 months, the patient should be referred to a gynaecologist for further assessment.

In summary, healthcare professionals should consider the patient’s medical history and preferences when selecting a treatment for primary dysmenorrhoea. Paracetamol and hormonal contraceptives are suitable first-line treatments, while NSAIDs and TENS may also be effective in some patients. Referral to a specialist may be necessary if initial treatments are not effective.

Understanding Ovarian Hyperstimulation Syndrome

Ovarian hyperstimulation syndrome (OHSS) is a potential complication that can occur during infertility treatment. This condition is believed to be caused by the presence of multiple luteinized cysts in the ovaries, which can lead to high levels of hormones and vasoactive substances. As a result, the permeability of the membranes increases, leading to fluid loss from the intravascular compartment.

OHSS is more commonly seen following gonadotropin or hCG treatment, and it is rare with Clomiphene therapy. Approximately one-third of women undergoing in vitro fertilization (IVF) may experience a mild form of OHSS. The Royal College of Obstetricians and Gynaecologists (RCOG) has classified OHSS into four categories: mild, moderate, severe, and critical.

Symptoms of OHSS can range from abdominal pain and bloating to more severe symptoms such as thromboembolism and acute respiratory distress syndrome. It is important to monitor patients closely during infertility treatment to detect any signs of OHSS and manage the condition appropriately. By understanding OHSS and its potential risks, healthcare providers can work to minimize the occurrence of this complication and ensure the safety of their patients.

The most reliable way to confirm ovulation is through the Day 21 progesterone test. This test measures the peak level of progesterone in the serum, which occurs 7 days after ovulation. While the length of the follicular phase can vary, the luteal phase always lasts for 14 days. Therefore, if a woman has a 35-day cycle, she can expect to ovulate on Day 21 and her progesterone level will peak on Day 28. To determine when to take the test, subtract 7 days from the expected start of the next period (Day 21 for a 28-day cycle and Day 28 for a 35-day cycle). Basal body temperature charts and cervical mucous thickness are not reliable predictors of ovulation. Gonadotropins may be used to assess ovarian function in women with irregular menstrual cycles.

Infertility is a common issue that affects approximately 1 in 7 couples. It is important to note that around 84% of couples who have regular sexual intercourse will conceive within the first year, and 92% within the first two years. The causes of infertility can vary, with male factor accounting for 30%, unexplained causes accounting for 20%, ovulation failure accounting for 20%, tubal damage accounting for 15%, and other causes accounting for the remaining 15%.

When investigating infertility, there are some basic tests that can be done. These include a semen analysis and a serum progesterone test. The serum progesterone test is done 7 days prior to the expected next period, typically on day 21 for a 28-day cycle. The interpretation of the serum progesterone level is as follows: if it is less than 16 nmol/l, it should be repeated and if it remains consistently low, referral to a specialist is necessary. If the level is between 16-30 nmol/l, it should be repeated, and if it is greater than 30 nmol/l, it indicates ovulation.

It is important to counsel patients on lifestyle factors that can impact fertility. This includes taking folic acid, maintaining a healthy BMI between 20-25, and advising regular sexual intercourse every 2 to 3 days. Additionally, patients should be advised to quit smoking and limit alcohol consumption to increase their chances of conceiving.

Pelvic floor muscle training is the most effective and cost-efficient treatment for stress urinary incontinence in women. Ring pessaries can also be used as a non-surgical option for pelvic organ prolapse. Oxybutynin is typically used for urge incontinence, but in this scenario, the woman only experiences stress incontinence. While a referral to urogynaecology may be considered for further investigation or surgery, it is not necessary to do so urgently. Pelvic floor exercises should be attempted for at least 3 months under the guidance of a continence adviser, specialist nurse, or women’s health physiotherapist. As the woman’s symptoms persist despite 6 months of trying this approach, it would be inappropriate to suggest continuing with the same strategy.

Understanding Urinary Incontinence: Causes, Classification, and Management

Urinary incontinence (UI) is a common condition that affects around 4-5% of the population, with elderly females being more susceptible. Several risk factors contribute to UI, including advancing age, previous pregnancy and childbirth, high body mass index, hysterectomy, and family history. UI can be classified into different types, such as overactive bladder (OAB)/urge incontinence, stress incontinence, mixed incontinence, overflow incontinence, and functional incontinence.

Initial investigation of UI involves completing bladder diaries for at least three days, vaginal examination, urine dipstick and culture, and urodynamic studies. Management of UI depends on the predominant type of incontinence. For urge incontinence, bladder retraining and bladder stabilizing drugs such as antimuscarinics are recommended. For stress incontinence, pelvic floor muscle training and surgical procedures such as retropubic mid-urethral tape procedures may be offered. Duloxetine, a combined noradrenaline and serotonin reuptake inhibitor, may also be used as an alternative to surgery.

In summary, understanding the causes, classification, and management of UI is crucial in providing appropriate care for patients. Early diagnosis and intervention can significantly improve the quality of life for those affected by this condition.

Injectable progesterone contraceptives are not recommended for individuals with current breast cancer.

This is considered an absolute contraindication (UKMEC 4) for prescribing injectable progesterone contraceptives. It is also an absolute contraindication for most other forms of contraception, except for the non-hormonal copper intrauterine device.

Current deep vein thrombosis is a UKMEC 2 contraindication for injectable progesterone, while it is a UKMEC 4 contraindication for the combined oral contraceptive pill. Multiple cardiovascular risk factors are a UKMEC 3 contraindication, which is not absolute, but the risks are generally considered to outweigh the benefits.

Smoking 30 cigarettes per day is only a UKMEC 1 contraindication for injectable progesterone contraception. However, considering the individual’s age, it would be a UKMEC 4 contraindication for the combined oral contraceptive pill.

High BMI is a UKMEC 1 contraindication for most forms of contraception, including injectable progesterone. However, it would be a UKMEC 4 contraindication for the combined pill.

Injectable Contraceptives: Depo Provera

Injectable contraceptives are a popular form of birth control in the UK, with Depo Provera being the main option available. This contraceptive contains 150 mg of medroxyprogesterone acetate and is administered via intramuscular injection every 12 weeks. It can be given up to 14 weeks after the last dose without the need for extra precautions. The primary method of action is by inhibiting ovulation, while secondary effects include cervical mucous thickening and endometrial thinning.

However, there are some disadvantages to using Depo Provera. Once the injection is given, it cannot be reversed, and there may be a delayed return to fertility of up to 12 months. Adverse effects may include irregular bleeding and weight gain, and there is a potential increased risk of osteoporosis. It should only be used in adolescents if no other method of contraception is suitable.

It is important to note that there are contraindications to using Depo Provera, such as current breast cancer (UKMEC 4) or past breast cancer (UKMEC 3). While Noristerat is another injectable contraceptive licensed in the UK, it is rarely used in clinical practice and is given every 8 weeks. Overall, injectable contraceptives can be an effective form of birth control, but it is important to weigh the potential risks and benefits before deciding on this method.

Injectable progesterone contraceptives should not be used in individuals with current breast cancer, as it is an absolute contraindication as per the UK medical eligibility criteria. Smoking more than 15 cigarettes a day is also a contraindication for the combined oral contraceptive pill, while migraine with aura is a contraindication for the same. Additionally, unexplained vaginal bleeding is a contraindication for starting the intrauterine device (IUD) or the intrauterine system (IUS).

Overall, injectable contraceptives can be an effective form of birth control, but it is important to weigh the potential risks and benefits before deciding on this method.

Possible Diagnoses for Hirsutism and Menstrual Irregularity in Reproductive-Age Women

Hirsutism and menstrual irregularity in reproductive-age women can be caused by various conditions. Polycystic ovarian syndrome (PCOS) and late-onset (non-classic) congenital adrenal hyperplasia are two possible diagnoses to consider. In this case, the normal 17-hydroxyprogesterone concentration rules out congenital adrenal hyperplasia, while the presence of bilaterally enlarged ovaries with multiple cysts and impaired glucose tolerance suggests PCOS.

An androgen-secreting adrenal tumour can also cause hirsutism, but it typically results in rapid onset and severe symptoms. Ovarian stromal hyperthecosis, which shares some resemblance with PCOS, may occur in premenopausal and postmenopausal women, but PCOS is more likely in this case due to the ultrasound scan findings.

Late-onset congenital adrenal hyperplasia can present with gradual onset of hirsutism without virilisation, but an elevated serum 17-hydroxyprogesterone concentration is a distinguishing feature. Luteoma of pregnancy, a benign solid ovarian tumour associated with excess androgen production, is unlikely in this case as the patient has not been pregnant.

In summary, PCOS is the most likely diagnosis for this patient’s hirsutism and menstrual irregularity, based on the ultrasound appearance and hormone results.

A high vaginal swab is not necessary for diagnosing vaginal candidiasis if the symptoms strongly suggest its presence. Symptoms such as genital itching and white discharge are indicative of Candida albicans infection. The discharge appears like cottage cheese and causes inflammation and itching, but the vaginal pH remains normal (around 4.0-4.5 in women of reproductive age). Since vaginal candidiasis is a common condition, a confident clinical suspicion based on the examination can be enough to diagnose and initiate treatment.

The other options for diagnosis are incorrect. Gardnerella vaginalis is a normal part of the vaginal flora, but it’s overgrowth can lead to bacterial vaginosis. Unlike vaginal candidiasis, bacterial vaginosis presents with thinner white discharge and a fishy odor that intensifies with the addition of potassium hydroxide. Additionally, the vaginal pH would be elevated (> 4.5).

Vaginal candidiasis, also known as thrush, is a common condition that many women can diagnose and treat themselves. Candida albicans is responsible for about 80% of cases, while other candida species cause the remaining 20%. Although most women have no predisposing factors, certain factors such as diabetes mellitus, antibiotics, steroids, pregnancy, and HIV can increase the likelihood of developing vaginal candidiasis. Symptoms include non-offensive discharge resembling cottage cheese, vulvitis, itching, vulval erythema, fissuring, and satellite lesions. A high vaginal swab is not routinely indicated if the clinical features are consistent with candidiasis. Treatment options include local or oral therapy, with oral fluconazole 150 mg as a single dose being the first-line treatment according to NICE Clinical Knowledge Summaries. If there are vulval symptoms, a topical imidazole may be added to an oral or intravaginal antifungal. Pregnant women should only use local treatments. Recurrent vaginal candidiasis is defined as four or more episodes per year by BASHH. Compliance with previous treatment should be checked, and a high vaginal swab for microscopy and culture should be performed to confirm the diagnosis. A blood glucose test may be necessary to exclude diabetes, and differential diagnoses such as lichen sclerosus should be ruled out. An induction-maintenance regime involving oral fluconazole may be considered. Induction involves taking oral fluconazole every three days for three doses, while maintenance involves taking oral fluconazole weekly for six months.

Starting hormonal contraception immediately after using levonorgestrel emergency contraceptive pill is safe. However, if ulipristal was used, hormonal contraception should be started or restarted after 5 days, and barrier methods should be used during this time. Waiting for 7 or 30 days before starting hormonal contraception is unnecessary as levonorgestrel does not affect its efficacy. A pregnancy test is only recommended if the patient’s next period is more than 5-7 days late or lighter than usual, not routinely after taking levonorgestrel.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

The most effective form of contraception for young women who desire a low-maintenance option and do not want to remember to take it daily is the implantable contraceptive. This option is particularly suitable for those with busy or unpredictable lifestyles, such as those planning to travel. While the intrauterine device is also effective for 5 years, it is contraindicated for those with active pelvic inflammatory disease. The implantable contraceptive, which lasts for 3 years, is a better option in this case. Injectable contraceptive is less suitable as it only lasts for 12 weeks.

Implanon and Nexplanon are subdermal contraceptive implants that slowly release the progesterone hormone etonogestrel to prevent ovulation and thicken cervical mucous. Nexplanon is the newer version and has a redesigned applicator to prevent deep insertions and is radiopaque for easier location. It is highly effective with a failure rate of 0.07/100 women-years and lasts for 3 years. It does not contain estrogen, making it suitable for women with a past history of thromboembolism or migraine. It can be inserted immediately after a termination of pregnancy. However, a trained professional is needed for insertion and removal, and additional contraceptive methods are required for the first 7 days if not inserted on days 1 to 5 of a woman’s menstrual cycle.

The main disadvantage of these implants is irregular and heavy bleeding, which can be managed with a co-prescription of the combined oral contraceptive pill. Other adverse effects include headache, nausea, and breast pain. Enzyme-inducing drugs such as certain antiepileptic and rifampicin may reduce the efficacy of Nexplanon, and women should switch to a method unaffected by enzyme-inducing drugs or use additional contraception until 28 days after stopping the treatment.

There are also contraindications for using these implants, such as ischaemic heart disease/stroke, unexplained, suspicious vaginal bleeding, past breast cancer, severe liver cirrhosis, and liver cancer. Current breast cancer is a UKMEC 4 condition, which represents an unacceptable risk if the contraceptive method is used. Overall, these implants are a highly effective and long-acting form of contraception, but they require careful consideration of the potential risks and contraindications.

The patient should not restart the COCP within the first 21 days after giving birth due to the increased risk of venous thromboembolism. However, since the patient is not breastfeeding and has no additional risk factors for thromboembolic disease, she can safely restart the pill at 3 weeks postpartum. Restarting at any other time before the 21-day mark is not recommended.

After giving birth, women need to use contraception after 21 days. The progesterone-only pill (POP) can be started at any time postpartum, according to the FSRH. Additional contraception should be used for the first two days after day 21. A small amount of progesterone enters breast milk, but it is not harmful to the infant. On the other hand, the combined oral contraceptive pill (COCP) is absolutely contraindicated (UKMEC 4) if breastfeeding is less than six weeks post-partum. If breastfeeding is between six weeks and six months postpartum, it is a UKMEC 2. The COCP may reduce breast milk production in lactating mothers. It should not be used in the first 21 days due to the increased venous thromboembolism risk post-partum. After day 21, additional contraception should be used for the first seven days. The intrauterine device or intrauterine system can be inserted within 48 hours of childbirth or after four weeks.

The lactational amenorrhoea method (LAM) is 98% effective if the woman is fully breastfeeding (no supplementary feeds), amenorrhoeic, and less than six months post-partum. It is important to note that an inter-pregnancy interval of less than 12 months between childbirth and conceiving again is associated with an increased risk of preterm birth, low birth weight, and small for gestational age babies.

If two consecutive samples are deemed inadequate during cervical cancer screening, the correct course of action is to refer the patient for colposcopy. Repeating the smear in 1 or 3 months is not appropriate as two inadequate samples have already been taken. Requesting hrHPV testing from the laboratory is also not useful if the sample is inadequate. Referring the patient to gynaecology is not necessary, and instead, a referral for colposcopy should be made.

The cervical cancer screening program has evolved to include HPV testing, which allows for further risk stratification. A negative hrHPV result means a return to normal recall, while a positive result requires cytological examination. Abnormal cytology results lead to colposcopy, while normal cytology results require a repeat test at 12 months. Inadequate samples require a repeat within 3 months, and two consecutive inadequate samples lead to colposcopy. Treatment for CIN typically involves LLETZ or cryotherapy. Individuals who have been treated for CIN should be invited for a test of cure repeat cervical sample 6 months after treatment.

Treatment Options for Vulval Cancer: Simple Vulvectomy and Bilateral Inguinal Lymphadenectomy

Vulval cancer is a rare form of cancer that accounts for less than 1% of cancer diagnoses. The labia majora are the most common site, followed by labia minora. Squamous cell carcinoma is the most common type of vulval cancer, with carcinoma-in-situ being a precursor lesion that does not invade through the basement membrane. Risk factors for developing vulval cancer include increasing age, exposure to HPV, vulval lichen sclerosus et atrophicus, smoking, and immunosuppression.

Patients may present with symptoms such as itching, pain, easy-contact bleeding of the vulva, changes in vulval skin, or frank ulcers/masses. The first lymph node station for metastases is the inguinal group. Surgery is the primary treatment for vulval cancer, with a simple vulvectomy and bilateral inguinal lymphadenectomy being the usual surgery performed, even in the absence of clinically palpable groin lymph nodes.

Radiotherapy is commonly used before and/or after surgery depending on the stage of the disease, but it is not curative and would not be offered in isolation to an otherwise healthy patient. Chemotherapy is not usually used as a primary treatment but is offered in disseminated malignancy. Wide local excision is only used for lesions less than 2 cm in diameter with a depth of less than 1 mm. Lesions larger than this require vulvectomy and lymph node clearance due to the risk of metastasis.

In conclusion, a simple vulvectomy and bilateral inguinal lymphadenectomy are the mainstay of treatment for vulval cancer, with radiotherapy and chemotherapy being used in certain cases. Early detection and treatment are crucial for improving outcomes in patients with vulval cancer.

Endometrial cancer is the cause of PMB in a minority of patients, with vaginal atrophy being the most common cause. Approximately 90% of patients with PMB do not have endometrial cancer.

Understanding Postmenopausal Bleeding

Postmenopausal bleeding refers to vaginal bleeding that occurs after a woman has gone 12 months without a menstrual period. While most cases do not involve cancer, it is important to rule out this possibility in all women. The most common cause of postmenopausal bleeding is vaginal atrophy, which occurs due to a reduction in estrogen following menopause. Other causes include hormone replacement therapy, endometrial hyperplasia, endometrial cancer, cervical cancer, ovarian cancer, and vaginal cancer.

To investigate postmenopausal bleeding, women over the age of 55 should undergo an ultrasound within two weeks to check for endometrial cancer. If referred on a cancer pathway, a transvaginal ultrasound is the preferred method of investigation. Treatment options depend on the underlying cause of the bleeding. For vaginal atrophy, topical estrogen and lifestyle changes can help alleviate symptoms, while HRT may also be used. If the bleeding is due to a specific type of HRT, switching to a different preparation may be helpful. In cases of endometrial hyperplasia, dilation and curettage may be necessary to remove excess tissue.

Overall, it is important for women experiencing postmenopausal bleeding to seek medical attention and undergo appropriate testing to rule out any serious underlying conditions.

To ensure maximum safety when switching from a traditional POP to COCP, it is recommended to use barrier contraception for 7 days while starting the combined oral contraceptive. This is the standard duration of protection required when starting this medication outside of menstruation. It is not necessary to use barrier contraception for 10 or 14 days, as the standard recommendation is 7 days. Using barrier contraception for only 3 days is too short, as it is the duration recommended for starting a traditional progesterone-only pill. While there may be some protection, it is still advisable to use additional contraception for 7 days to prevent unwanted pregnancy.

Special Situations for Combined Oral Contraceptive Pill

Concurrent antibiotic use has been a concern for many years in the UK, as doctors have advised that it may interfere with the effectiveness of the combined oral contraceptive pill. However, this approach is not taken in the US or most of mainland Europe. In 2011, the Faculty of Sexual & Reproductive Healthcare updated their guidelines to abandon the extra precautions previously advised during antibiotic treatment and for 7 days afterwards. The latest edition of the British National Formulary (BNF) has also been updated to reflect this guidance, although precautions should still be taken with enzyme-inducing antibiotics such as rifampicin.

When it comes to switching combined oral contraceptive pills, the BNF and Faculty of Sexual & Reproductive Healthcare (FSRH) appear to give contradictory advice. The FSRH’s Combined Oral Contraception guidelines state that the pill-free interval does not need to be omitted, while the BNF advises missing the pill-free interval if the progesterone changes. Given this uncertainty, it is best to follow the BNF’s advice.

The most effective method of emergency contraception is a copper IUD, and it should be the first option offered to all women who have had unprotected sexual intercourse. This IUD can be used up to 5 days after the UPSI or the earliest estimated date of ovulation. The combined oral contraceptive pill, intrauterine system, and levonorgestrel are not as effective as the copper IUD and should not be the first option offered. Levonorgestrel can only be used within 72 hours of UPSI, and even then, the copper IUD is still more effective.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

Endometrial cancer is a type of cancer that is commonly found in women who have gone through menopause, but it can also occur in around 25% of cases before menopause. The prognosis for this type of cancer is usually good due to early detection. There are several risk factors associated with endometrial cancer, including obesity, nulliparity, early menarche, late menopause, unopposed estrogen, diabetes mellitus, tamoxifen, polycystic ovarian syndrome, and hereditary non-polyposis colorectal carcinoma. Postmenopausal bleeding is the most common symptom of endometrial cancer, which is usually slight and intermittent initially before becoming more heavy. Pain is not common and typically signifies extensive disease, while vaginal discharge is unusual.

When investigating endometrial cancer, women who are 55 years or older and present with postmenopausal bleeding should be referred using the suspected cancer pathway. The first-line investigation is trans-vaginal ultrasound, which has a high negative predictive value for a normal endometrial thickness (< 4 mm). Hysteroscopy with endometrial biopsy is also commonly used for investigation. The management of localized disease involves total abdominal hysterectomy with bilateral salpingo-oophorectomy, while patients with high-risk disease may have postoperative radiotherapy. progesterone therapy is sometimes used in frail elderly women who are not considered suitable for surgery. It is important to note that the combined oral contraceptive pill and smoking are protective against endometrial cancer.

Distinguishing between common vaginal infections: Trichomoniasis, Bacterial Vaginosis, gonorrhoeae, Chlamydia, and Mycoplasma Genitalium

When a woman presents with an elevated vaginal pH, a fish-smelling, yellow vaginal discharge, and ovoid trichomonads, the diagnosis of trichomoniasis (Trichomonas vaginalis) is strongly supported. A wet saline mount or anaerobic culture can confirm the diagnosis, with culture being particularly useful in men. Treatment involves oral metronidazole for seven days or a single 2g dose, and sexual partners should also be treated to prevent re-infection.

Bacterial vaginosis is a differential diagnosis to consider, as it also presents with a fish-smelling discharge and a pH > 4.5. However, the presence of ovoid mobile parasites on wet saline mount suggests trichomoniasis as the more likely diagnosis. Bacterial vaginosis would show clue cells on wet saline mount.

gonorrhoeae and Chlamydia are sexually transmitted infections that are more likely to be seen in patients with a history of unprotected sex. However, fish-smelling discharge is not characteristic of either infection. A specimen culture of gonorrhoeae would show Gram-negative diplococci, while chlamydia would not show ovoid mobile parasites on wet saline mount.

Mycoplasma genitalium is another potential sexually transmitted infection that can cause urethritis, discharge, cervicitis, or endometritis in women. However, the wet saline mount results suggest that this is not the diagnosis, and fish-smelling discharge is not characteristic of this infection.

In summary, a combination of clinical presentation, wet saline mount, and culture can help distinguish between common vaginal infections such as trichomoniasis, bacterial vaginosis, gonorrhoeae, chlamydia, and mycoplasma genitalium.

Diagnostic Tests for Abdominal Pain in Women of Childbearing Age

Abdominal pain in women of childbearing age requires a thorough diagnostic workup to rule out gynaecological emergencies such as ectopic pregnancy. The following diagnostic tests should be considered:

1. Pregnancy test (beta-human chorionic gonadotrophin (β-hCG)): This test should be the first step in the diagnostic workup to rule out ectopic pregnancy. A positive result requires urgent referral to the gynaecological team.

2. Full blood count: This test may indicate an ongoing infective process or other pathology, but a pregnancy test should be done first to rule out ectopic pregnancy.

3. Ultrasound of the abdomen and pelvis: Imaging may be useful in determining the cause of the pain, but a pregnancy test should be done first before considering imaging studies.

4. Urine culture and sensitivity: This test may be useful if a urinary tract infection and possible pyelonephritis are considered, but an ectopic pregnancy has to be ruled out first.

5. Erect chest X-ray: This test can show free air under the diaphragm, indicating a ruptured viscus and a surgical emergency. However, a pregnancy test should be done first to rule out ectopic pregnancy.

In conclusion, a thorough diagnostic workup is necessary to determine the cause of abdominal pain in women of childbearing age, with a pregnancy test being the first step to rule out gynaecological emergencies.

The addition of progesterone to hormone replacement therapy (HRT) has been found to raise the risk of breast cancer. It is worth noting that taking low doses of progesterone alone, without oestrogen, does not seem to have the same effect on breast cancer risk. If used for less than 10 years, oestrogen-only HRT does not appear to increase the likelihood of developing breast cancer. However, it does increase the risk of endometrial cancer and should be avoided unless the patient has had a hysterectomy.

Adverse Effects of Hormone Replacement Therapy

Hormone replacement therapy (HRT) is a treatment that involves the use of a small dose of oestrogen, often combined with a progesterone in women with a uterus, to alleviate menopausal symptoms. While it can be effective in reducing symptoms such as hot flashes and vaginal dryness, HRT can also have adverse effects and potential complications.

Some common side-effects of HRT include nausea, breast tenderness, fluid retention, and weight gain. However, there are also more serious potential complications associated with HRT. For example, the use of HRT has been linked to an increased risk of breast cancer, particularly when a progesterone is added. The Women’s Health Initiative study found a relative risk of 1.26 at 5 years of developing breast cancer with HRT use. The risk of breast cancer is also related to the duration of use, and it begins to decline when HRT is stopped.

Another potential complication of HRT is an increased risk of endometrial cancer. Oestrogen by itself should not be given as HRT to women with a womb, as this can increase the risk of endometrial cancer. The addition of a progesterone can reduce this risk, but it is not eliminated completely. The British National Formulary states that the additional risk is eliminated if a progesterone is given continuously.

HRT has also been associated with an increased risk of venous thromboembolism (VTE), particularly when a progesterone is added. However, transdermal HRT does not appear to increase the risk of VTE. Women who are at high risk for VTE should be referred to haematology before starting any treatment, even transdermal, according to the National Institute for Health and Care Excellence (NICE).

Finally, HRT has been linked to an increased risk of stroke and ischaemic heart disease if taken more than 10 years after menopause. It is important for women considering HRT to discuss the potential risks and benefits with their healthcare provider and make an informed decision based on their individual circumstances.

Understanding Endometriosis

Endometriosis is a common condition where endometrial tissue grows outside of the uterus. It affects around 10% of women of reproductive age and can cause chronic pelvic pain, painful periods, painful intercourse, and subfertility. Other symptoms may include urinary problems and painful bowel movements. Diagnosis is typically made through laparoscopy, and treatment options depend on the severity of symptoms.

First-line treatments for symptomatic relief include NSAIDs and/or paracetamol. If these do not help, hormonal treatments such as the combined oral contraceptive pill or progestogens may be tried. If symptoms persist or fertility is a priority, referral to secondary care may be necessary. Secondary treatments may include GnRH analogues or surgery. For women trying to conceive, laparoscopic excision or ablation of endometriosis plus adhesiolysis is recommended, as well as ovarian cystectomy for endometriomas.

It is important to note that there is poor correlation between laparoscopic findings and severity of symptoms, and that there is little role for investigation in primary care. If symptoms are significant, referral for a definitive diagnosis is recommended.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

The use of COCP as a first-line contraceptive should be avoided for wheelchair users due to their increased risk of developing deep vein thrombosis (DVT). The presence of oestradiol in COCP increases the risk of DVT, and immobility associated with wheelchair use further exacerbates this risk. Therefore, the risks of using COCP outweigh the benefits for wheelchair users, and it is classified as UKMEC 3.

The decision to prescribe the combined oral contraceptive pill is now based on the UK Medical Eligibility Criteria (UKMEC), which categorizes potential contraindications and cautions on a four-point scale. UKMEC 1 indicates no restrictions for use, while UKMEC 2 suggests that the benefits outweigh the risks. UKMEC 3 indicates that the disadvantages may outweigh the advantages, and UKMEC 4 represents an unacceptable health risk. Examples of UKMEC 3 conditions include controlled hypertension, a family history of thromboembolic disease in first-degree relatives under 45 years old, and current gallbladder disease. Examples of UKMEC 4 conditions include a history of thromboembolic disease or thrombogenic mutation, breast cancer, and uncontrolled hypertension. Diabetes mellitus diagnosed over 20 years ago is classified as UKMEC 3 or 4 depending on severity. In 2016, Breastfeeding between 6 weeks and 6 months postpartum was changed from UKMEC 3 to UKMEC 2.

If a patient with stress incontinence does not respond to pelvic floor muscle exercises and declines surgical intervention, duloxetine may be used. Antimuscarinics are the first-line treatment for urge incontinence in patients who do not respond to bladder training, with oxybutynin (immediate-release), tolterodine (immediate-release), or darifenacin (once daily preparation) being recommended by NICE. Mirabegron, a beta-3 agonist, is used when antimuscarinics are contraindicated or when there are concerns about their side effects, particularly in frail elderly women. Desmopressin is not a treatment for stress incontinence, but it may be considered off-label for patients with troublesome nocturia, except for women aged 65 years or over with cardiovascular disease or hypertension.

Understanding Urinary Incontinence: Causes, Classification, and Management

Urinary incontinence (UI) is a common condition that affects around 4-5% of the population, with elderly females being more susceptible. Several risk factors contribute to UI, including advancing age, previous pregnancy and childbirth, high body mass index, hysterectomy, and family history. UI can be classified into different types, such as overactive bladder (OAB)/urge incontinence, stress incontinence, mixed incontinence, overflow incontinence, and functional incontinence.

Initial investigation of UI involves completing bladder diaries for at least three days, vaginal examination, urine dipstick and culture, and urodynamic studies. Management of UI depends on the predominant type of incontinence. For urge incontinence, bladder retraining and bladder stabilizing drugs such as antimuscarinics are recommended. For stress incontinence, pelvic floor muscle training and surgical procedures such as retropubic mid-urethral tape procedures may be offered. Duloxetine, a combined noradrenaline and serotonin reuptake inhibitor, may also be used as an alternative to surgery.

In summary, understanding the causes, classification, and management of UI is crucial in providing appropriate care for patients. Early diagnosis and intervention can significantly improve the quality of life for those affected by this condition.

Recommended Investigations for Abdominal Pain in Women of Childbearing Age

Abdominal pain in women of childbearing age requires careful investigation to rule out potential life-threatening conditions such as ectopic pregnancy. The following investigations are recommended:

1. Pregnancy test: All women of childbearing age presenting with abdominal pain must have a pregnancy test to rule out an ectopic pregnancy, regardless of the location of the pain.

2. Abdominal radiograph: This may be the next investigation following the pregnancy test, to rule out bowel obstruction.

3. Ultrasound: This may be indicated to assess for appendicitis, gallstone disease, or ovarian torsion, among others. However, this should take place after testing for pregnancy.

4. Exploratory laparoscopy: This would be too invasive at this stage but may take place after investigation.

5. Prophylactic antibiotics: This will be indicated if the patient requires abdominal surgery, but at present, we do not know if this patient has an abdominal, gynaecological, or urology pathology. Prophylactic antibiotics would be premature at this point.

In conclusion, a thorough investigation is necessary to determine the cause of abdominal pain in women of childbearing age. The above investigations should be conducted in a systematic manner to ensure timely and accurate diagnosis.

A labial lump and inguinal lymphadenopathy in an older woman may indicate the presence of vulval carcinoma, as these symptoms are concerning and should not be ignored. Although labial lumps are not uncommon, it is important to be vigilant and seek medical attention if a new lump appears.

Understanding Vulval Carcinoma

Vulval carcinoma is a type of cancer that affects the vulva, which is the external female genitalia. It is a relatively rare condition, with only around 1,200 cases diagnosed in the UK each year. The majority of cases occur in women over the age of 65 years, and around 80% of cases are squamous cell carcinomas.

There are several risk factors associated with vulval carcinoma, including human papillomavirus (HPV) infection, vulval intraepithelial neoplasia (VIN), immunosuppression, and lichen sclerosus. Symptoms of vulval carcinoma may include a lump or ulcer on the labia majora, inguinal lymphadenopathy, and itching or irritation.

It is important for women to be aware of the risk factors and symptoms of vulval carcinoma, and to seek medical attention if they experience any concerning symptoms. Early detection and treatment can improve outcomes and increase the chances of a full recovery.

To follow up on a positive hrHPV result with a cytologically normal sample, it is recommended to repeat the smear after 12 months as HPV can be naturally cleared by the immune system within this timeframe.

The cervical cancer screening program has evolved to include HPV testing, which allows for further risk stratification. A negative hrHPV result means a return to normal recall, while a positive result requires cytological examination. Abnormal cytology results lead to colposcopy, while normal cytology results require a repeat test at 12 months. Inadequate samples require a repeat within 3 months, and two consecutive inadequate samples lead to colposcopy. Treatment for CIN typically involves LLETZ or cryotherapy. Individuals who have been treated for CIN should be invited for a test of cure repeat cervical sample 6 months after treatment.

During pregnancy, fibroid degeneration can occur and may cause symptoms such as low-grade fever, pain, and vomiting.

If the ultrasound scan does not show any signs of inflammation in the appendix, it is unlikely that the patient has appendicitis.

Since the patient has fibroids in her uterus, she is at risk of experiencing fibroid degeneration, which is a common complication during pregnancy. Symptoms of fibroid degeneration may include fever, pain, and vomiting.

The absence of vaginal bleeding makes it unlikely that the patient is experiencing a threatened miscarriage.

While ovarian torsion can cause pain and vomiting, it typically occurs in patients with risk factors such as ovarian cysts or ovarian enlargement.

Understanding Fibroid Degeneration

Uterine fibroids are non-cancerous growths that can develop in the uterus. They are sensitive to oestrogen and can grow during pregnancy. However, if the growth of the fibroids exceeds their blood supply, they can undergo a type of degeneration known as red or ‘carneous’ degeneration. This condition is characterized by symptoms such as low-grade fever, pain, and vomiting.

Fortunately, fibroid degeneration can be managed conservatively with rest and analgesia. With proper care, the symptoms should resolve within 4-7 days.

Understanding Cervical Screening: Guidelines and Options

Cervical screening, also known as a smear test, is a vital tool in detecting precancerous cell changes in the cervix and preventing cervical cancer. Here are some important guidelines and options to keep in mind:

Age and Frequency: In the UK, women aged 25-64 are invited for screening, with those aged 25-49 screened every three years and those aged 50-64 screened every five years. In Scotland, screening is recommended every five years for women aged 25-65.

Hysterectomy: Women who have had a total hysterectomy (removal of the uterus and cervix) do not require cervical screening. However, those who have had a partial hysterectomy (removal of the uterus but not the cervix) should continue to be screened according to age guidelines.

Age Limit: Women over the age of 65 may still be eligible for screening if they have had recent abnormal results or have not been screened since the age of 50.

Opting Out: While cervical screening is not obligatory, it is highly recommended. Patients can opt out by speaking to their doctor and signing an ‘opting out’ form, but this decision can be reversed at any time. It is important to understand the benefits and risks associated with screening before making a decision.

If a patient’s cervical smear shows abnormal cytology and a positive result for a high-risk strain of human papillomavirus, the next step is to refer them for colposcopy to obtain a cervical biopsy and assess for cervical cancer. This patient cannot be discharged to normal recall as they are at significant risk of developing cervical cancer. If the cytology is inadequate, it can be retested in 3 months. However, if the cytology shows low-grade dyskaryosis, colposcopy and further assessment are necessary. Delaying the repeat cytology for 6 months would not be appropriate. If the cytology is normal but the patient is positive for high-risk human papillomavirus, retesting for human papillomavirus in 12 months is appropriate. However, if abnormal cytology is present with high-risk human papillomavirus, colposcopy and further assessment are needed.

The cervical cancer screening program has evolved to include HPV testing, which allows for further risk stratification. A negative hr HPV result means a return to normal recall, while a positive result requires cytological examination. Abnormal cytology results lead to colposcopy, while normal cytology results require a repeat test at 12 months. Inadequate samples require a repeat within 3 months, and two consecutive inadequate samples lead to colposcopy. Treatment for CIN typically involves LLETZ or cryotherapy. Individuals who have been treated for CIN should be invited for a test of cure repeat cervical sample 6 months after treatment.

Contraceptive Options for Patients with Uterine Fibroids and Carbamazepine Use

Patients with uterine fibroids and concurrent use of carbamazepine may have limited contraceptive options due to drug interactions and uterine cavity distortion. The progesterone-only injectable is a suitable option as it does not interact with enzyme inducers and is not affected by uterine cavity distortion. The copper intrauterine device and levonorgestrel-releasing intrauterine system are not recommended in this case. The progesterone-only implant and combined oral contraceptive pill have severe interactions with carbamazepine, reducing their efficacy. It is important to consider individual patient factors and discuss all available contraceptive options with them.

On ultrasound imaging, the presence of a whirlpool sign and free fluid may indicate ovarian torsion. This sign occurs when a structure twists upon itself. It is important to note that appendicitis and ectopic pregnancy do not show this sign on imaging. Additionally, the pain associated with Mittelschmerz is typically less severe and would not be accompanied by the ultrasound finding.

Understanding Ovarian Torsion

Ovarian torsion is a medical condition that occurs when the ovary twists on its supporting ligaments, leading to a compromised blood supply. This condition can be partial or complete and may also affect the fallopian tube, which is then referred to as adnexal torsion. Women who have an ovarian mass, are of reproductive age, pregnant, or have ovarian hyperstimulation syndrome are at a higher risk of developing ovarian torsion.

The most common symptom of ovarian torsion is sudden, severe abdominal pain that is colicky in nature. Patients may also experience vomiting, distress, and in some cases, fever. Upon examination, adnexal tenderness may be detected, and an ultrasound may show free fluid or a whirlpool sign. Laparoscopy is usually both diagnostic and therapeutic for this condition.

Tranexamic acid is the recommended first-line non-hormonal treatment for menorrhagia, particularly for this patient who is trying to conceive. The contraceptive pill and IUS are not suitable options, and endometrial ablation is not recommended for those who wish to have children in the future. As the patient’s periods are painless, mefenamic acid is not necessary. Tranexamic acid is an anti-fibrinolytic that prevents heavy menstrual bleeding by inhibiting plasminogen activators. This treatment aligns with the guidelines set by NICE for managing heavy menstrual bleeding.

Managing Heavy Menstrual Bleeding

Heavy menstrual bleeding, also known as menorrhagia, is a condition where a woman experiences excessive blood loss during her menstrual cycle. While it was previously defined as total blood loss of over 80 ml per cycle, the management of menorrhagia now depends on the woman’s perception of what is excessive. In the past, hysterectomy was a common treatment for heavy periods, but the approach has changed significantly since the 1990s.

To manage menorrhagia, a full blood count should be performed in all women. If symptoms suggest a structural or histological abnormality, a routine transvaginal ultrasound scan should be arranged. For women who do not require contraception, mefenamic acid or tranexamic acid can be used. If there is no improvement, other drugs can be tried while awaiting referral.

For women who require contraception, options include the intrauterine system (Mirena), combined oral contraceptive pill, and long-acting progestogens. Norethisterone can also be used as a short-term option to rapidly stop heavy menstrual bleeding. The flowchart below shows the management of menorrhagia.

[Insert flowchart here]

Hysterectomy: Antibiotic Prophylaxis and Surgical Considerations

Hysterectomy is a surgical procedure that involves the removal of the uterus and is commonly used to treat pelvic pathologies such as fibroids and adenomyosis. Antibiotic prophylaxis is crucial during the operation to prevent infection, and Co-amoxiclav ® is a broad-spectrum antibiotic that is commonly used. Complications of hysterectomy include haemorrhage, trauma to the bowel, damage to the urinary tract, infection, thromboembolic disease, and an increased risk of vaginal prolapse. Vaginal hysterectomy is preferred over abdominal hysterectomy as it reduces post-operative morbidity and has a shorter recovery time. The decision to remove ovaries during abdominal hysterectomy depends on various factors such as the patient’s age, family history of breast and ovarian cancer, and plans for hormone replacement therapy. Subtotal hysterectomy is an option for women with dysfunctional uterine bleeding who have normal cervical cytology. Intraoperative prophylactic-dose heparin is not recommended as it can cause excessive bleeding. Penicillin V and trimethoprim are not suitable for intraoperative prophylaxis as they do not provide broad-spectrum cover. Amoxicillin is inadequate for this operation as it does not provide the necessary prophylaxis during the intraoperative period.

It is a common scenario for surgical patients to face an increased risk of venous thromboembolism when they are on the pill and undergoing surgery, particularly abdominal or lower limb surgery. Therefore, it is necessary to discontinue the pill.

However, stopping the pill too early would increase the risk of pregnancy, and restarting it too soon after surgery would still pose a risk due to the surgery’s effects on coagulation. Ceasing the pill on the day of surgery would not eliminate the risk of clotting either.

The best course of action is to stop the pill four weeks before surgery to allow for a return to normal coagulation levels. Then, restarting it two weeks after surgery would allow the procoagulant effects of surgery to subside.

The decision to prescribe the combined oral contraceptive pill is now based on the UK Medical Eligibility Criteria (UKMEC), which categorizes potential contraindications and cautions on a four-point scale. UKMEC 1 indicates no restrictions for use, while UKMEC 2 suggests that the benefits outweigh the risks. UKMEC 3 indicates that the disadvantages may outweigh the advantages, and UKMEC 4 represents an unacceptable health risk. Examples of UKMEC 3 conditions include controlled hypertension, a family history of thromboembolic disease in first-degree relatives under 45 years old, and current gallbladder disease. Examples of UKMEC 4 conditions include a history of thromboembolic disease or thrombogenic mutation, breast cancer, and uncontrolled hypertension. Diabetes mellitus diagnosed over 20 years ago is classified as UKMEC 3 or 4 depending on severity. In 2016, Breastfeeding between 6 weeks and 6 months postpartum was changed from UKMEC 3 to UKMEC 2.

If a patient’s cervical cancer screening sample is positive for high-risk HPV and shows cytological abnormalities, the next step according to guidelines is to refer the patient for a colposcopy. During this procedure, the cervix is closely examined to identify any disease. If significant abnormalities are found, loop excision of the transformation zone may be necessary. It is not appropriate to return the patient to normal recall without further investigation. Repeating the sample in 3 months is not necessary for a patient with high-risk HPV and requires specialist assessment. However, repeating the sample in 3 months may be considered if the initial sample was inadequate. Similarly, repeating the sample in 12 months is not the next step and may only be recommended after colposcopy. At this stage, the patient needs further assessment. Repeating the sample in 12 months may be considered if the patient has high-risk HPV with normal cytological findings.

The cervical cancer screening program has evolved to include HPV testing, which allows for further risk stratification. A negative hrHPV result means a return to normal recall, while a positive result requires cytological examination. Abnormal cytology results lead to colposcopy, while normal cytology results require a repeat test at 12 months. Inadequate samples require a repeat within 3 months, and two consecutive inadequate samples lead to colposcopy. Treatment for CIN typically involves LLETZ or cryotherapy. Individuals who have been treated for CIN should be invited for a test of cure repeat cervical sample 6 months after treatment.

Levonorgestrel can still be taken within 72 hours of unprotected sexual intercourse (UPSI) in this case. Ulipristal acetate can also be taken up to 120 hours later, but the efficacy of oral options may have decreased after 61 hours. The copper coil is not a suitable option as the patient has declined any form of birth control. Therefore, the correct answer is that levonorgestrel can still be taken within 72 hours of UPSI.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

To confirm ovulation, it is recommended to take a serum progesterone level 7 days before the expected next period. If the level is above 30 nmol/l, it indicates ovulation and other causes of infertility should be considered. However, if the level is below 30 nmol/l, it does not necessarily exclude the possibility of ovulation, but repeat testing is required. If the level remains consistently low, referral to a specialist is necessary. It is important to note that the length of a menstrual cycle can vary, so 7 days prior to the next period is a more accurate time to take the test than relying on day 21 of a 28-day cycle.

Infertility is a common issue that affects approximately 1 in 7 couples. It is important to note that around 84% of couples who have regular sexual intercourse will conceive within the first year, and 92% within the first two years. The causes of infertility can vary, with male factor accounting for 30%, unexplained causes accounting for 20%, ovulation failure accounting for 20%, tubal damage accounting for 15%, and other causes accounting for the remaining 15%.

When investigating infertility, there are some basic tests that can be done. These include a semen analysis and a serum progesterone test. The serum progesterone test is done 7 days prior to the expected next period, typically on day 21 for a 28-day cycle. The interpretation of the serum progesterone level is as follows: if it is less than 16 nmol/l, it should be repeated and if it remains consistently low, referral to a specialist is necessary. If the level is between 16-30 nmol/l, it should be repeated, and if it is greater than 30 nmol/l, it indicates ovulation.

It is important to counsel patients on lifestyle factors that can impact fertility. This includes taking folic acid, maintaining a healthy BMI between 20-25, and advising regular sexual intercourse every 2 to 3 days. Additionally, patients should be advised to quit smoking and limit alcohol consumption to increase their chances of conceiving.

Pregnant women with a BMI greater than 30 kg/m2 should be prescribed a high dose of 5mg folic acid instead of the standard 400 micrograms. Therefore, the lifestyle and dietary advice given to this patient is incorrect. Additionally, prescribing 75 mg of aspirin is not appropriate for this patient as it is typically given to women with one high-risk factor or two moderate-risk factors for pre-eclampsia, and a BMI over 35 would only qualify as a single moderate-risk factor. While 150 mg of aspirin is an alternative dose for pre-eclampsia prophylaxis, 75 mg is more commonly used in practice.

Folic Acid: Importance, Deficiency, and Prevention

Folic acid is a vital nutrient that is converted to tetrahydrofolate (THF) in the body. It is found in green, leafy vegetables and plays a crucial role in the transfer of 1-carbon units to essential substrates involved in the synthesis of DNA and RNA. However, certain factors such as phenytoin, methotrexate, pregnancy, and alcohol excess can cause a deficiency in folic acid. This deficiency can lead to macrocytic, megaloblastic anemia and neural tube defects.

To prevent neural tube defects during pregnancy, it is recommended that all women take 400mcg of folic acid until the 12th week of pregnancy. Women at higher risk of conceiving a child with a neural tube defect should take 5mg of folic acid from before conception until the 12th week of pregnancy. Women are considered higher risk if they or their partner has a neural tube defect, they have had a previous pregnancy affected by a neural tube defect, or they have a family history of a neural tube defect. Additionally, women with certain medical conditions such as coeliac disease, diabetes, or thalassaemia trait, or those taking antiepileptic drugs, or who are obese (BMI of 30 kg/m2 or more) are also considered higher risk.

In summary, folic acid is an essential nutrient that plays a crucial role in DNA and RNA synthesis. Deficiency in folic acid can lead to serious health consequences, including neural tube defects. However, taking folic acid supplements during pregnancy can prevent these defects and ensure a healthy pregnancy.

Tumour Markers: An Overview

Tumour markers are substances produced by cancer cells or normal cells in response to cancer. They can be used to aid in the diagnosis, monitoring, and treatment of cancer. Here are some commonly used tumour markers and their applications:

CA125: This marker is used to detect ovarian cancer. It should be tested if a woman has persistent abdominal bloating, early satiety, pelvic or abdominal pain, increased urinary urgency or frequency, or symptoms consistent with irritable bowel syndrome. If CA125 is raised, the patient should be referred for a pelvic/abdominal ultrasound scan.

AFP: Elevated AFP levels are associated with hepatocellular carcinoma, liver metastases, and non-seminomatous germ-cell tumours. It is also measured in pregnant women to screen for neural-tube defects or genetic disorders.

CA15-3: This marker is used to monitor the response to treatment in breast cancer. It should not be used for screening as it is not necessarily raised in early breast cancer. Other causes of raised CA15-3 include liver cirrhosis, hepatitis, autoimmune conditions, and benign disorders of the ovary or breast.

CA19-9: This marker is commonly associated with pancreatic cancer. It may also be seen in other hepatobiliary and gastric malignancies.

CEA: CEA is commonly used as a tumour marker for colorectal cancer. It is not particularly sensitive or specific, so it is usually used to monitor response to treatment or detect disease recurrence.

If a patient vomits within 3 hours of taking levonorgestrel, it is recommended to prescribe a second dose of emergency hormonal contraception to be taken as soon as possible, according to NICE guidelines. Therefore, reassuring Zoe that she is protected from pregnancy is incorrect as she needs to take another dose. Additionally, while it may be advisable for Zoe to start a regular form of contraception, this is not the most important advice to give initially. Instead, she should be offered choices of contraception, including long-acting reversible contraceptives. It is also incorrect to recommend other forms of emergency contraception, such as ulipristal acetate and the IUD, as Zoe has already taken levonorgestrel and the guidelines are clear that a second dose of this should be taken in this circumstance. However, if Zoe experiences persistent vomiting or diarrhea for more than 24 hours after taking emergency hormonal contraception, then the IUD may be offered.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

If a patient presents with symptoms highly suggestive of vaginal candidiasis, a high vaginal swab is not necessary for diagnosis and treatment can be initiated with a single oral dose of fluconazole. Symptoms of vaginal candidiasis include vulval soreness, itching, and thick, white vaginal discharge. Prescribing oral metronidazole as a single dose or taking a high vaginal swab would be incorrect as they are used to treat Trichomonas vaginalis infections or bacterial vaginosis, respectively.

Vaginal candidiasis, also known as thrush, is a common condition that many women can diagnose and treat themselves. Candida albicans is responsible for about 80% of cases, while other candida species cause the remaining 20%. Although most women have no predisposing factors, certain factors such as diabetes mellitus, antibiotics, steroids, pregnancy, and HIV can increase the likelihood of developing vaginal candidiasis. Symptoms include non-offensive discharge resembling cottage cheese, vulvitis, itching, vulval erythema, fissuring, and satellite lesions. A high vaginal swab is not routinely indicated if the clinical features are consistent with candidiasis. Treatment options include local or oral therapy, with oral fluconazole 150 mg as a single dose being the first-line treatment according to NICE Clinical Knowledge Summaries. If there are vulval symptoms, a topical imidazole may be added to an oral or intravaginal antifungal. Pregnant women should only use local treatments. Recurrent vaginal candidiasis is defined as four or more episodes per year by BASHH. Compliance with previous treatment should be checked, and a high vaginal swab for microscopy and culture should be performed to confirm the diagnosis. A blood glucose test may be necessary to exclude diabetes, and differential diagnoses such as lichen sclerosus should be ruled out. An induction-maintenance regime involving oral fluconazole may be considered. Induction involves taking oral fluconazole every three days for three doses, while maintenance involves taking oral fluconazole weekly for six months.

The effectiveness of different contraceptives varies in terms of the time it takes to become effective if not started on the first day of the menstrual cycle. The intrauterine device is the only method that is instantly effective at any time during the cycle as it reduces sperm motility and survival. The progesterone only pill takes at least 2 days to work if started after day 5 of the cycle and is immediately effective if started prior to day 5. The combined oral contraceptive pill, injection, implant, and intrauterine system take 7 days to become effective and work by inhibiting ovulation, thickening cervical mucous, and preventing endometrial proliferation. Side effects of the progesterone only pill may include menstrual irregularities, breast tenderness, weight gain, and acne.

Counselling for Women Considering the progesterone-Only Pill

Women who are considering taking the progesterone-only pill (POP) should receive counselling on various aspects of the medication. One of the most common potential adverse effects is irregular vaginal bleeding. When starting the POP, immediate protection is provided if it is commenced up to and including day 5 of the cycle. If it is started later, additional contraceptive methods such as condoms should be used for the first 2 days. If switching from a combined oral contraceptive (COC), immediate protection is provided if the POP is continued directly from the end of a pill packet.

It is important to take the POP at the same time every day, without a pill-free break, unlike the COC. If a pill is missed by less than 3 hours, it should be taken as normal. If it is missed by more than 3 hours, the missed pill should be taken as soon as possible, and extra precautions such as condoms should be used until pill taking has been re-established for 48 hours. Diarrhoea and vomiting do not affect the POP, but assuming pills have been missed and following the above guidelines is recommended. Antibiotics have no effect on the POP, unless they alter the P450 enzyme system, such as rifampicin. Liver enzyme inducers may reduce the effectiveness of the POP.

In addition to these specific guidelines, women should also have a discussion on sexually transmitted infections (STIs) when considering the POP. It is important for women to receive comprehensive counselling on the POP to ensure they are aware of its potential effects and how to use it effectively.

The most effective treatment for large fibroids that are causing fertility problems is myomectomy, especially if the patient wishes to conceive in the future. Fibroids may not cause any symptoms, but they can lead to menorrhagia, bloating, dysuria, and sub-fertility. Medical therapies like anti-progestogens and gonadotrophin-releasing hormone agonists may temporarily reduce fibroid size, but they can also interfere with fertility. Surgical treatment, specifically myomectomy, is necessary in cases where fibroids are distorting the uterine cavity and affecting fertility. Myomectomy has been shown to improve fertility outcomes. The combined oral contraceptive pill may help reduce bleeding associated with fibroids, but it does not affect fibroid size and is not suitable for patients with sub-fertility due to fibroids. Endometrial ablation destroys the endometrial lining and reduces menstrual bleeding but is not appropriate for patients who desire fertility. Uterine artery embolisation is only recommended for patients who do not want to conceive as it can lead to obstetric risks such as placental abnormalities.

Understanding Uterine Fibroids

Uterine fibroids are non-cancerous growths that develop in the uterus. They are more common in black women and are thought to occur in around 20% of white women in their later reproductive years. Fibroids are usually asymptomatic, but they can cause menorrhagia, which can lead to iron-deficiency anaemia. Other symptoms include lower abdominal pain, bloating, and urinary symptoms. Fibroids may also cause subfertility.

Diagnosis is usually made through transvaginal ultrasound. Asymptomatic fibroids do not require treatment, but periodic monitoring is recommended. Menorrhagia secondary to fibroids can be managed with various treatments, including the levonorgestrel intrauterine system, NSAIDs, tranexamic acid, and hormonal therapies.

Medical treatment to shrink or remove fibroids may include GnRH agonists or ulipristal acetate, although the latter is not currently recommended due to concerns about liver toxicity. Surgical options include myomectomy, hysteroscopic endometrial ablation, hysterectomy, and uterine artery embolization.

Fibroids generally regress after menopause, but complications such as subfertility and iron-deficiency anaemia can occur. Red degeneration, which is haemorrhage into the tumour, is a common complication during pregnancy.
