Having endometriosis increases the risk of experiencing an ectopic pregnancy. This patient’s symptoms and positive pregnancy test suggest a likely diagnosis of an ectopic pregnancy. Other risk factors for ectopic pregnancy include previous ectopic pregnancy, fallopian tube damage, and IVF. However, multiparity, previous pre-eclampsia, twin pregnancy, and type 2 diabetes mellitus are not associated with an increased risk of ectopic pregnancy.

Understanding Ectopic Pregnancy: Incidence and Risk Factors

Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, usually in the fallopian tubes. This condition is a serious medical emergency that requires immediate attention. According to epidemiological studies, ectopic pregnancy occurs in approximately 0.5% of all pregnancies.

Several risk factors can increase the likelihood of ectopic pregnancy. These include damage to the fallopian tubes due to pelvic inflammatory disease or surgery, a history of previous ectopic pregnancy, endometriosis, the use of intrauterine contraceptive devices (IUCDs), and the progesterone-only pill. In vitro fertilization (IVF) also increases the risk of ectopic pregnancy, with approximately 3% of IVF pregnancies resulting in ectopic implantation.

It is important to note that any factor that slows down the passage of the fertilized egg to the uterus can increase the risk of ectopic pregnancy. Early detection and prompt treatment are crucial in managing this condition and preventing serious complications.

The earliest possible time for an anomaly scan is at 18 weeks, with the latest being at 20 weeks and 6 days. For a dating scan, the earliest possible time is at 8 weeks. As for a nuchal scan, it can be done at the earliest at 11 weeks.

NICE guidelines recommend 10 antenatal visits for first pregnancies and 7 for subsequent pregnancies if uncomplicated. The purpose of each visit is outlined, including booking visits, scans, screening for Down’s syndrome, routine care for blood pressure and urine, and discussions about labour and birth plans. Rhesus negative women are offered anti-D prophylaxis at 28 and 34 weeks. The guidelines also recommend discussing options for prolonged pregnancy at 41 weeks.

Breast masses are a common concern among women, and it is important to understand the possible causes to determine the appropriate course of action. Here are some of the most common causes of breast masses and their characteristics:

Fibroadenoma: This is the most common cause of breast mass in women under 35 years old. It appears as a singular, firm, rubbery, smooth, mobile, painless mass ranging in size from 1 cm to 5 cm. Ultrasonography reveals a well-defined, hypoechoic, homogeneous mass 1–20 cm in diameter.

Fat Necrosis: This is a benign inflammatory process that occurs when there is saponification of local fat. It can result from direct trauma or nodular panniculitis. The breast mass is usually firm, round, and painless, and there may be a single mass or multiple masses. It may be tender or painful in some people.

Breast Abscess: This usually presents with localised breast oedema, erythema, warmth, and pain. There may be associated symptoms of fever, nausea, vomiting, spontaneous drainage from the mass or nipple, and a history of previous breast infection.

Breast Cancer: Early breast cancer may be asymptomatic, and pain and discomfort are typically not present. It is often first detected as an abnormality on a mammogram before it is felt by the patient or healthcare professional. If a lump is discovered, there may be a change in breast size or shape, skin dimpling or skin changes, recent nipple inversion or skin change, or nipple abnormalities.

Lipoma: Lipomas are common benign tumors composed of mature adipocytes that typically present clinically as well-circumscribed, soft, mobile, nontender masses. The classic mammographic appearance of lipoma is a circumscribed fat-containing mass.

It is important to note that the physical examination findings may not always be enough to determine the cause of the breast mass, and further testing may be necessary. Consultation with a healthcare professional is recommended for proper diagnosis and treatment.

Understanding Trichomonas vaginalis and its Comparison to Bacterial Vaginosis

Trichomonas vaginalis is a type of protozoan parasite that is highly motile and flagellated. It is known to cause trichomoniasis, which is a sexually transmitted infection. The infection is characterized by symptoms such as offensive, yellow/green, frothy vaginal discharge, vulvovaginitis, and strawberry cervix. The pH level is usually above 4.5, and in men, it may cause urethritis.

To diagnose trichomoniasis, a wet mount microscopy is conducted to observe the motile trophozoites. The treatment for trichomoniasis involves oral metronidazole for 5-7 days, although a one-off dose of 2g metronidazole may also be used.

When compared to bacterial vaginosis, trichomoniasis has distinct differences. Bacterial vaginosis is caused by an overgrowth of bacteria in the vagina, while trichomoniasis is caused by a protozoan parasite. The symptoms of bacterial vaginosis include a thin, grayish-white vaginal discharge with a fishy odor, and a pH level above 4.5. Unlike trichomoniasis, bacterial vaginosis is not considered a sexually transmitted infection.

In conclusion, understanding the differences between trichomoniasis and bacterial vaginosis is crucial in diagnosing and treating these conditions effectively. Proper diagnosis and treatment can help prevent complications and improve overall health and well-being.

Urinary incontinence is a common problem that affects more women than men and increases with age. There are different types of urinary incontinence, each with its own set of symptoms. Functional incontinence occurs when a person is unable to hold urine due to reasons other than lower urinary tract dysfunction, such as delirium or impaired mobility. Mixed incontinence is a combination of stress and urge incontinence, while overflow incontinence occurs when the bladder is overdistended and urine overflows despite the absence of detrusor contraction. Stress incontinence is characterized by urine loss during periods of increased intra-abdominal pressure, while urge incontinence is associated with a sudden and intense desire to void that cannot be prevented. Symptoms of urge incontinence include urinary frequency and nocturia. Treatment is directed at the underlying cause of the incontinence.

Venous thromboembolism (VTE) is a serious condition that can lead to severe health complications and even death. However, it is preventable. The National Institute for Health and Care Excellence (NICE) has updated its guidelines for 2018 to provide recommendations for the assessment and management of patients at risk of VTE in hospital. All patients admitted to the hospital should be assessed individually to identify risk factors for VTE development and bleeding risk. The department of health’s VTE risk assessment tool is recommended for medical and surgical patients. Patients with certain risk factors, such as reduced mobility, surgery, cancer, and comorbidities, are at increased risk of developing VTE. After assessing a patient’s VTE risk, healthcare professionals should compare it to their risk of bleeding to decide whether VTE prophylaxis should be offered. If indicated, VTE prophylaxis should be started as soon as possible.

There are two types of VTE prophylaxis: mechanical and pharmacological. Mechanical prophylaxis includes anti-embolism stockings and intermittent pneumatic compression devices. Pharmacological prophylaxis includes fondaparinux sodium, low molecular weight heparin (LMWH), and unfractionated heparin (UFH). The choice of prophylaxis depends on the patient’s individual risk factors and bleeding risk.

In general, medical patients deemed at risk of VTE after individual assessment are started on pharmacological VTE prophylaxis, provided that the risk of VTE outweighs the risk of bleeding and there are no contraindications. Surgical patients at low risk of VTE are treated with anti-embolism stockings, while those at high risk are treated with a combination of stockings and pharmacological prophylaxis.

Patients undergoing certain surgical procedures, such as hip and knee replacements, are recommended to receive pharmacological VTE prophylaxis to reduce the risk of VTE developing post-surgery. For fragility fractures of the pelvis, hip, and proximal femur, LMWH or fondaparinux sodium is recommended for a month if the risk of VTE outweighs the risk of bleeding.

Healthcare professionals should advise patients to stop taking their combined oral contraceptive pill or hormone replacement therapy four weeks before surgery and mobilize them as soon as possible after surgery. Patients should also ensure they are hydrated. By following these guidelines, healthcare professionals can help prevent VTE and improve patient outcomes.

Benefits and Risks of Oral Contraceptives

Oral contraceptives, also known as birth control pills, are a popular form of contraception for women. They contain synthetic hormones that prevent pregnancy by inhibiting ovulation, thickening cervical mucus, and altering the lining of the uterus. While oral contraceptives have many benefits, they also carry some risks.

Venous Thrombosis: The estrogen component of oral contraceptives can activate the blood-clotting mechanism, increasing the risk of venous thrombosis. However, low-dose oral contraceptives are associated with a lower risk of thromboembolism.

Benign Breast Disease: Oral contraceptives can prevent benign breast disease, but their association with breast cancer in young women is controversial. While some studies suggest a slightly increased risk of breast cancer, the risk is small and the resulting tumors spread less aggressively than usual.

Functional Ovarian Cysts: Oral contraceptives suppress ovarian stimulation, reducing the risk of developing functional ovarian cysts.

Carcinoma of the Ovary or Uterus: Oral contraceptives can prevent epithelial ovarian and endometrial carcinoma. They are associated with a 40% reduced risk of malignant and borderline ovarian epithelial cancer and a 50% reduction in the risk of endometrial adenocarcinoma.

Pelvic Inflammatory Disease: Oral contraceptives can prevent the development of pelvic inflammatory disease.

Overall, oral contraceptives are reliable and reversible, reduce menstrual symptoms, and lower the risk of certain cancers and pelvic inflammatory disease. However, they carry some risks, including an increased risk of venous thrombosis and a controversial association with breast cancer. Women should discuss the benefits and risks of oral contraceptives with their healthcare provider to determine if they are a suitable form of contraception.

Bacterial vaginosis during pregnancy can lead to various pregnancy-related issues, such as preterm labor. In the past, it was advised to avoid taking oral metronidazole during the first trimester. However, current guidelines suggest that it is safe to use throughout the entire pregnancy. For more information, please refer to the Clinical Knowledge Summary provided.

Bacterial vaginosis (BV) is a condition where there is an overgrowth of anaerobic organisms, particularly Gardnerella vaginalis, in the vagina. This leads to a decrease in the amount of lactobacilli, which produce lactic acid, resulting in an increase in vaginal pH. BV is not a sexually transmitted infection, but it is commonly seen in sexually active women. Symptoms include a fishy-smelling vaginal discharge, although some women may not experience any symptoms at all. Diagnosis is made using Amsel’s criteria, which includes the presence of thin, white discharge, clue cells on microscopy, a vaginal pH greater than 4.5, and a positive whiff test. Treatment involves oral metronidazole for 5-7 days, with a cure rate of 70-80%. However, relapse rates are high, with over 50% of women experiencing a recurrence within 3 months. Topical metronidazole or clindamycin may be used as alternatives.

Bacterial vaginosis during pregnancy can increase the risk of preterm labor, low birth weight, chorioamnionitis, and late miscarriage. It was previously recommended to avoid oral metronidazole in the first trimester and use topical clindamycin instead. However, recent guidelines suggest that oral metronidazole can be used throughout pregnancy. The British National Formulary (BNF) still advises against using high-dose metronidazole regimes. Clue cells, which are vaginal epithelial cells covered with bacteria, can be seen on microscopy in women with BV.

The use of combined oral contraceptive pills is completely contraindicated in patients with migraine with aura due to an increased risk of ischaemic stroke (UKMEC class 4). However, progestogen-based contraception methods and the levonorgestrel-releasing intrauterine device are considered safe (UKMEC 2) as the benefits of using these methods outweigh the potential risks. The copper intrauterine device is the only form of contraception recommended by UKMEC as having no contraindication in this condition (UKMEC 1).

Intrauterine contraceptive devices include copper IUDs and levonorgestrel-releasing IUS. Both are over 99% effective. The IUD prevents fertilization by decreasing sperm motility, while the IUS prevents endometrial proliferation and thickens cervical mucus. Potential problems include heavier periods with IUDs and initial bleeding with the IUS. There is a small risk of uterine perforation, ectopic pregnancy, and infection. New IUS systems, such as Jaydess® and Kyleena®, have smaller frames and less levonorgestrel, resulting in lower serum levels and different rates of amenorrhea.

There are several methods for screening and diagnosing Down’s syndrome in pregnancy. The nuchal translucency scan, which measures fluid in the fetal neck, is best done between 11 and 14 weeks and can detect an increased risk of genetic syndromes. The triple screen, which measures levels of certain hormones in the mother’s blood, is done in the second trimester and can detect up to 69% of cases in singleton pregnancies, but may have a higher false positive or false negative in twin pregnancies. Amniocentesis and chorionic villous sampling are invasive diagnostic tests that can detect chromosomal disorders with high accuracy, but carry a small risk of pregnancy loss. The routine anomaly scan should not be used for Down’s syndrome screening. Cell-free fetal DNA screening is a newer method that can detect about 99% of Down’s syndrome pregnancies, but is currently only offered by private clinics at a high cost. A positive screening result suggests an increased risk for Down’s syndrome, and definitive testing with chorionic villous sampling or amniocentesis is indicated.

Understanding Chorioamnionitis

Chorioamnionitis is a serious medical condition that can affect both the mother and the foetus during pregnancy. It is caused by a bacterial infection that affects the amniotic fluid, membranes, and placenta. This condition is considered a medical emergency and can be life-threatening if not treated promptly. It is more likely to occur when the membranes rupture prematurely, but it can also happen when the membranes are still intact.

Prompt delivery of the foetus is crucial in treating chorioamnionitis, and a cesarean section may be necessary. Intravenous antibiotics are also administered to help fight the infection. This condition affects up to 5% of all pregnancies, and it is important for pregnant women to be aware of the symptoms and seek medical attention immediately if they suspect they may have chorioamnionitis.

If a woman is over 35 years old and has been having regular intercourse for 6 months without conceiving, she should be investigated for infertility earlier. Regular sexual intercourse is defined as having intercourse every 2-3 days. However, if a woman is under 35 years old, investigation should wait until after 12 months of regular intercourse. It is important to consider early referral when the female has amenorrhea, previous pelvic surgery, abnormal genital examination, or is suffering from significant systemic illness. Similarly, early referral should be considered for males who have had previous surgery on genitalia, previous STI, varicocele, or abnormal genital examination.

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.

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, breast feeding between 6 weeks and 6 months postpartum was changed from UKMEC 3 to UKMEC 2.

During pregnancy, women are checked for anaemia twice – once at the initial booking visit (usually around 8-10 weeks) and again at 28 weeks. The National Institute for Health and Care Excellence (NICE) has set specific cut-off levels to determine if a pregnant woman requires oral iron therapy. These levels are less than 110 g/L in the first trimester, less than 105 g/L in the second and third trimesters, and less than 100 g/L postpartum.

If a woman’s iron levels fall below these cut-offs, she will be prescribed oral ferrous sulfate or ferrous fumarate. It is important to continue this treatment for at least three months after the iron deficiency has been corrected to allow the body to replenish its iron stores. By following these guidelines, healthcare professionals can help ensure that pregnant women receive the appropriate care to prevent and manage anaemia during pregnancy.

If a woman experiences secondary amenorrhoea and has low levels of gonadotrophins, it suggests that the cause is related to the hypothalamus. High levels of gonadotrophins would indicate premature ovarian failure, while high levels of LH and androgens would suggest polycystic ovarian syndrome. Normal levels of prolactin and thyroxine have been observed in this woman.

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 with no 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.

Understanding Puerperal Pyrexia

Puerperal pyrexia is a condition that occurs when a woman experiences a fever of more than 38ºC within the first 14 days after giving birth. The most common cause of this condition is endometritis, which is an infection of the lining of the uterus. Other causes include urinary tract infections, wound infections, mastitis, and venous thromboembolism.

If a woman is suspected of having endometritis, it is important to seek medical attention immediately. Treatment typically involves intravenous antibiotics such as clindamycin and gentamicin until the patient is afebrile for more than 24 hours. It is important to note that puerperal pyrexia can be a serious condition and should not be ignored. By understanding the causes and seeking prompt medical attention, women can receive the necessary treatment to recover from this condition.

Trichomonas vaginalis is linked to a strawberry cervix, which can have symptoms resembling those of bacterial vaginosis.

Bacterial vaginosis (BV) is a condition where there is an overgrowth of anaerobic organisms, particularly Gardnerella vaginalis, in the vagina. This leads to a decrease in the amount of lactobacilli, which produce lactic acid, resulting in an increase in vaginal pH. BV is not a sexually transmitted infection, but it is commonly seen in sexually active women. Symptoms include a fishy-smelling vaginal discharge, although some women may not experience any symptoms at all. Diagnosis is made using Amsel’s criteria, which includes the presence of thin, white discharge, clue cells on microscopy, a vaginal pH greater than 4.5, and a positive whiff test. Treatment involves oral metronidazole for 5-7 days, with a cure rate of 70-80%. However, relapse rates are high, with over 50% of women experiencing a recurrence within 3 months. Topical metronidazole or clindamycin may be used as alternatives.

Bacterial vaginosis during pregnancy can increase the risk of preterm labor, low birth weight, chorioamnionitis, and late miscarriage. It was previously recommended to avoid oral metronidazole in the first trimester and use topical clindamycin instead. However, recent guidelines suggest that oral metronidazole can be used throughout pregnancy. The British National Formulary (BNF) still advises against using high-dose metronidazole regimes. Clue cells, which are vaginal epithelial cells covered with bacteria, can be seen on microscopy in women with BV.

The recommended treatment for the patient’s likely diagnosis of trichomoniasis is oral metronidazole, either as a 7-day course of 200mg or a one-time dose of 2g. Intramuscular ceftriaxone, benzathine benzylpenicillin, and oral doxycycline are not indicated for the treatment of trichomoniasis. Oral azithromycin is also not effective for this condition.

Understanding Trichomonas vaginalis and its Comparison to Bacterial Vaginosis

Trichomonas vaginalis is a type of protozoan parasite that is highly motile and flagellated. It is known to cause trichomoniasis, which is a sexually transmitted infection. The infection is characterized by symptoms such as offensive, yellow/green, frothy vaginal discharge, vulvovaginitis, and strawberry cervix. The pH level is usually above 4.5, and in men, it may cause urethritis.

To diagnose trichomoniasis, a wet mount microscopy is conducted to observe the motile trophozoites. The treatment for trichomoniasis involves oral metronidazole for 5-7 days, although a one-off dose of 2g metronidazole may also be used.

When compared to bacterial vaginosis, trichomoniasis has distinct differences. Bacterial vaginosis is caused by an overgrowth of bacteria in the vagina, while trichomoniasis is caused by a protozoan parasite. The symptoms of bacterial vaginosis include a thin, grayish-white vaginal discharge with a fishy odor, and a pH level above 4.5. Unlike trichomoniasis, bacterial vaginosis is not considered a sexually transmitted infection.

In conclusion, understanding the differences between trichomoniasis and bacterial vaginosis is crucial in diagnosing and treating these conditions effectively. Proper diagnosis and treatment can help prevent complications and improve overall health and well-being.

Contraceptives – Time to become effective (if not used on the first day of period):
Immediate: IUD
2 days: Progestin-only pill (POP)
7 days: Combined oral contraceptive (COC), injection, implant, intrauterine system (IUS)

Intrauterine contraceptive devices include copper IUDs and levonorgestrel-releasing IUS. Both are over 99% effective. The IUD prevents fertilization by decreasing sperm motility, while the IUS prevents endometrial proliferation and thickens cervical mucus. Potential problems include heavier periods with IUDs and initial bleeding with the IUS. There is a small risk of uterine perforation, ectopic pregnancy, and infection. New IUS systems, such as Jaydess® and Kyleena®, have smaller frames and less levonorgestrel, resulting in lower serum levels and different rates of amenorrhea.

Medical treatment can be attempted for uterine fibroids that are smaller than 3 cm and do not distort the uterine cavity. This may include options such as an intrauterine system, tranexamic acid, or COCP. The NICE Clinical Knowledge Summaries suggest starting with an intrauterine system, which can also serve as a form of contraception.

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.

The most common adverse effect associated with the progesterone-only pill, also known as the ‘mini pill’, is irregular vaginal bleeding. Patients should be advised to take the pill at the same time every day without a pill-free break. While oily skin may occur due to increased sebum production, this is not as common as irregular vaginal bleeding. Patients with a history of acne vulgaris who take the progesterone-only pill may experience increased sebum production. The combined oral contraceptive pill (COCP) is commonly used to manage acne vulgaris and hirsutism in polycystic ovarian syndrome. Headaches may occur during the first few months of using hormonal contraception, but this is less likely to occur with the POP as the most common time to experience headaches is during the ‘pill-free interval’. Patients with a history of migraine with aura should be advised of the risks associated with the COCP and migraine with aura and informed that the POP is likely to be a safer alternative. While mood changes have been studied with birth control, there is no definite outcome of recent studies, and epidemiological data gathered by NICE does not support this as the most common adverse effect.

Counselling for Women Considering the Progestogen-Only Pill

Women who are considering taking the progestogen-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 copper intrauterine device is the recommended form of contraception for individuals with breast cancer. Hormonal forms of contraception are not recommended and are rated as a Category 4 risk, which is deemed unacceptable for the patient’s health.

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, breast feeding between 6 weeks and 6 months postpartum was changed from UKMEC 3 to UKMEC 2.

Antepartum hemorrhage can be caused by placental abruption, which may result in vaginal bleeding, abdominal pain, and a firm or woody uterus. In some cases, the bleeding may be concealed, and the fetus may be difficult to feel or hear. It is important to note that young and healthy women may not show signs of shock until they have lost a significant amount of blood. Contractions during labor typically come in waves and do not cause a woody or tender uterus or low blood pressure. Placenta previa is another common cause of antepartum hemorrhage, but it is usually painless.

Placental Abruption: Causes, Symptoms, and Risk Factors

Placental abruption is a condition that occurs when the placenta separates from the uterine wall, leading to maternal bleeding into the space between them. Although the exact cause of this condition is unknown, certain factors have been associated with it, including proteinuric hypertension, cocaine use, multiparity, maternal trauma, and increasing maternal age. Placental abruption is not a common occurrence, affecting approximately 1 in 200 pregnancies.

The clinical features of placental abruption include shock that is disproportionate to the visible blood loss, constant pain, a tender and tense uterus, and a normal lie and presentation of the fetus. The fetal heart may be absent or distressed, and there may be coagulation problems. It is important to be aware of other conditions that may present with similar symptoms, such as pre-eclampsia, disseminated intravascular coagulation (DIC), and anuria.

In summary, placental abruption is a serious condition that can have significant consequences for both the mother and the fetus. Understanding the risk factors and symptoms of this condition is important for early detection and appropriate management.

Progestogen Only Pill: What to Do When You Miss a Pill

The progestogen only pill (POP) has simpler rules for missed pills compared to the combined oral contraceptive pill. It is important to note that the rules for the two types of pills should not be confused. The traditional POPs (Micronor, Noriday, Nogeston, Femulen) and Cerazette (desogestrel) have the following guidelines for missed pills:

– If the pill is less than 3 hours late, no action is required, and you can continue taking the pill as normal.
– If the pill is more than 3 hours late (i.e., more than 27 hours since the last pill was taken), action is needed.
– If the pill is less than 12 hours late, no action is required, and you can continue taking the pill as normal.
– If the pill is more than 12 hours late (i.e., more than 36 hours since the last pill was taken), action is needed.

The copper intrauterine device is the only suitable method for this patient as it can be used as emergency contraception if inserted within 5 days of unprotected sexual intercourse or within 5 days of the estimated ovulation date, whichever is later. As the patient has a regular 28-day cycle and is currently at day 17, she is within the 5-day window for fitting of the IUD. Levonorgestrel, a tablet used for emergency contraception, would not be suitable as it must be taken within 72 hours of unprotected sexual intercourse. The Mirena intrauterine system is a hormonal device used for regular contraception but cannot be used as emergency contraception. Norethisterone is a drug used for dysfunctional uterine bleeding and period delay but not for emergency contraception.

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.

Women need to start using contraception only 21 days after giving birth during the post-partum period. It is recommended that they begin taking the combined contraceptive pill three weeks after delivery. However, if they are breastfeeding, they should wait for six weeks before starting the pill.

After giving birth, women need to use contraception after 21 days. The progestogen-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 progestogen 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.

Risks of Smoking, Alcohol, and Illegal Drugs During Pregnancy

During pregnancy, drug use can have serious consequences for both the mother and the developing fetus. Smoking during pregnancy increases the risk of miscarriage, pre-term labor, stillbirth, and sudden unexpected death in infancy. Alcohol consumption can lead to fetal alcohol syndrome, which can cause learning difficulties, characteristic facial features, and growth restrictions. Binge drinking is a major risk factor for fetal alcohol syndrome. Cannabis use poses similar risks to smoking due to the tobacco content. Cocaine use can lead to hypertension in pregnancy, including pre-eclampsia, and placental abruption. Fetal risks include prematurity and neonatal abstinence syndrome. Heroin use can result in neonatal abstinence syndrome. It is important for pregnant women to avoid drug use to ensure the health and well-being of both themselves and their unborn child.

Labetalol is the preferred initial medication for treating hypertension during pregnancy. While methyldopa is an option, it is not recommended as the first choice due to its association with a higher risk of postpartum depression. Ramipril, irbesartan, and bendroflumethiazide should be avoided during pregnancy as they can cause birth defects.

Hypertension during pregnancy is a common occurrence that requires careful management. In normal pregnancies, blood pressure tends to decrease in the first trimester and then gradually increase to pre-pregnancy levels by term. However, in cases of hypertension during pregnancy, the systolic blood pressure is usually above 140 mmHg or the diastolic blood pressure is above 90 mmHg. Additionally, an increase of more than 30 mmHg systolic or 15 mmHg diastolic from the initial readings may also indicate hypertension.

There are three categories of hypertension during pregnancy: pre-existing hypertension, pregnancy-induced hypertension (PIH), and pre-eclampsia. Pre-existing hypertension refers to a history of hypertension before pregnancy or elevated blood pressure before 20 weeks gestation. PIH occurs in the second half of pregnancy and resolves after birth. Pre-eclampsia is characterized by hypertension and proteinuria, and may also involve edema.

The management of hypertension during pregnancy involves the use of antihypertensive medications such as labetalol, nifedipine, and hydralazine. In cases of pre-existing hypertension, ACE inhibitors and angiotensin II receptor blockers should be stopped immediately and alternative medications should be prescribed. Women who are at high risk of developing pre-eclampsia should take aspirin from 12 weeks until the birth of the baby. It is important to carefully monitor blood pressure and proteinuria levels during pregnancy to ensure the health of both the mother and the baby.

If a pregnant woman is exposed to chickenpox before 20 weeks and has a negative IgG test, it indicates that she is not immune to the virus or has not been previously exposed to it. In such cases, it is recommended to administer varicella-zoster immunoglobulin (VZIG) as soon as possible, which can be effective up to 10 days after exposure. It is not necessary to inform public health as chickenpox is not a notifiable disease.

If a pregnant woman develops a chickenpox rash, VZIG has no therapeutic benefit and should not be used. However, antiviral agents like aciclovir can be given within 24 hours of the rash onset. It is important to note that antiviral agents are recommended for post-exposure prophylaxis for immunosuppressed individuals.

Women who are not immune to varicella-zoster can receive the vaccine before pregnancy or after delivery, but it should not be administered during pregnancy. Therefore, option D cannot be correct in any situation.

Chickenpox exposure in pregnancy can pose risks to both the mother and fetus, including fetal varicella syndrome. Post-exposure prophylaxis (PEP) with varicella-zoster immunoglobulin (VZIG) or antivirals should be given to non-immune pregnant women, with timing dependent on gestational age. If a pregnant woman develops chickenpox, specialist advice should be sought and oral aciclovir may be given if she is ≥ 20 weeks and presents within 24 hours of onset of the rash.

Understanding Premenstrual Syndrome (PMS)

Premenstrual syndrome (PMS) is a condition that affects women during the luteal phase of their menstrual cycle. It is characterized by emotional and physical symptoms that can range from mild to severe. PMS only occurs in women who have ovulatory menstrual cycles and does not occur before puberty, during pregnancy, or after menopause.

Emotional symptoms of PMS include anxiety, stress, fatigue, and mood swings. Physical symptoms may include bloating and breast pain. The severity of symptoms varies from woman to woman, and management options depend on the severity of symptoms.

Mild symptoms can be managed with lifestyle advice, such as getting enough sleep, exercising regularly, and avoiding smoking and alcohol. Specific advice includes eating regular, frequent, small, balanced meals that are rich in complex carbohydrates.

Moderate symptoms may benefit from a new-generation combined oral contraceptive pill (COCP), such as Yasmin® (drospirenone 3 mg and ethinylestradiol 0.030 mg). Severe symptoms may benefit from a selective serotonin reuptake inhibitor (SSRI), which can be taken continuously or just during the luteal phase of the menstrual cycle (for example, days 15-28, depending on the length of the cycle). Understanding PMS and its management options can help women better cope with this common condition.
