In the UK, it is recommended that all women who are HIV-positive should not breastfeed their babies. This advice remains the same even if the mother’s viral load is undetectable. The decision should not be left to the HIV consultant as the national guidelines are clear on this matter. Although breastfeeding may reduce the risk of transmission if the maternal viral load is less than 50 copies/ml, there is still a risk involved. Therefore, the advice remains not to breastfeed. Continuing with antiretroviral therapy is expected regardless of the decision not to breastfeed as it significantly reduces the risk of vertical transmission during pregnancy. Babies born to HIV-positive mothers are given antiretroviral therapy, either zidovudine alone if the maternal viral load is less than 50 copies/ml or triple-therapy if it is higher. However, this does not change the advice to avoid breastfeeding.

HIV and Pregnancy: Guidelines for Minimizing Vertical Transmission

With the increasing prevalence of HIV infection among heterosexual individuals, there has been a rise in the number of HIV-positive women giving birth in the UK. In fact, in London alone, the incidence may be as high as 0.4% of pregnant women. The primary goal of treating HIV-positive women during pregnancy is to minimize harm to both the mother and fetus, and to reduce the chance of vertical transmission.

To achieve this goal, various factors must be considered. Firstly, all pregnant women should be offered HIV screening, according to NICE guidelines. Additionally, antiretroviral therapy should be offered to all pregnant women, regardless of whether they were taking it previously. This therapy has been shown to significantly reduce vertical transmission rates, which can range from 25-30% to just 2%.

The mode of delivery is also an important consideration. Vaginal delivery is recommended if the viral load is less than 50 copies/ml at 36 weeks. If the viral load is higher, a caesarean section is recommended, and a zidovudine infusion should be started four hours before the procedure. Neonatal antiretroviral therapy is also typically administered to the newborn, with zidovudine being the preferred medication if the maternal viral load is less than 50 copies/ml. If the viral load is higher, triple ART should be used, and therapy should be continued for 4-6 weeks.

Finally, infant feeding is an important consideration. In the UK, all women should be advised not to breastfeed, as this can increase the risk of vertical transmission. By following these guidelines, healthcare providers can help to minimize the risk of vertical transmission and ensure the best possible outcomes for both mother and child.

Penile cancer can manifest as an ulcer. The most prevalent form of penile cancer is squamous cell carcinoma, not adenocarcinoma. While stress ulcers cause abdominal pain and bleeding, they are not responsible for this presentation. Herpes outbreaks can be triggered by significant stress, but they typically cause painful lesions that heal within a week. Syphilis, caused by Treponema pallidum, can result in a painless ulcer called a chancre, but it does not cause weight loss, and the lesion usually resolves within six to eight weeks, even without treatment.

Understanding Penile Cancer: Causes, Symptoms, and Treatment

Penile cancer is a rare type of cancer that is typically characterized by squamous cell carcinoma. It is a condition that affects the penis and can cause a variety of symptoms, including penile lump and ulceration. There are several risk factors associated with penile cancer, including human immunodeficiency virus infection, human papillomavirus virus infection, genital warts, poor hygiene, phimosis, paraphimosis, balanitis, and age over 50.

When it comes to treating penile cancer, there are several options available, including radiotherapy, chemotherapy, and surgery. The prognosis for penile cancer can vary depending on the stage of the cancer and the treatment options chosen. However, the overall survival rate for penile cancer is approximately 50% at 5 years.

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.

Recommendations for a Couple Struggling with Infertility

When a couple is struggling to conceive, there are several recommendations that healthcare providers may suggest. Firstly, if the couple has been trying to conceive for a year without success, they should be referred to fertility services. However, if there is an underlying reason for conception difficulties, earlier investigation may be necessary. In cases where the male partner is taking non-steroidal anti-inflammatory drugs, there is no impact on his ability to conceive. A hernia repair is not indicated to improve the couple’s chances of conception. Watching and waiting is not appropriate, and referral to fertility services is recommended. Finally, while sertraline and other SSRIs are not teratogenic, they can cause sexual dysfunction, which should be explored with the patient.

Differential Diagnosis of a Woman with Acne and Infertility

Polycystic ovarian syndrome (PCOS), endogenous Cushing’s syndrome, Addison’s disease, congenital adrenal hyperplasia (CAH), and primary hypoparathyroidism are all potential differential diagnoses for a woman presenting with acne and infertility. PCOS is the most likely diagnosis, as it presents with menstrual dysfunction, anovulation, and signs of hyperandrogenism, including excess terminal body hair in a male distribution pattern, acne, and male-pattern hair loss. Endogenous Cushing’s syndrome and primary hypoparathyroidism are less likely, as they do not present with acne and infertility. Addison’s disease is characterized by hyperpigmentation, weakness, fatigue, poor appetite, and weight loss, while CAH may present with oligomenorrhoea, hirsutism, and/or infertility.

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.

According to NICE guidelines, clinicians should diagnose pelvic inflammatory disease based on clinical symptoms and start antibiotic treatment promptly. While investigations such as endocervical and high vaginal swabs for microscopy and culture should be performed, they should not delay treatment. Negative swab results do not exclude the possibility of the disease. Blood cultures are not necessary unless the patient shows signs of systemic illness. Transvaginal ultrasound is not the first choice but may be necessary if an abscess is suspected.
(NICE CKS – Pelvic Inflammatory Disease)

Understanding Pelvic Inflammatory Disease

Pelvic inflammatory disease (PID) is a condition that occurs when the female pelvic organs, including the uterus, fallopian tubes, ovaries, and surrounding peritoneum, become infected and inflamed. The most common cause of PID is an ascending infection from the endocervix, often caused by Chlamydia trachomatis. Other causative organisms include Neisseria gonorrhoeae, Mycoplasma genitalium, and Mycoplasma hominis. Symptoms of PID include lower abdominal pain, fever, dyspareunia, dysuria, menstrual irregularities, vaginal or cervical discharge, and cervical excitation.

To diagnose PID, a pregnancy test should be done to rule out an ectopic pregnancy, and a high vaginal swab should be taken to screen for Chlamydia and Gonorrhoea. However, these tests are often negative, so consensus guidelines recommend having a low threshold for treatment due to the potential complications of untreated PID. Management typically involves a combination of antibiotics, such as oral ofloxacin and oral metronidazole or intramuscular ceftriaxone, oral doxycycline, and oral metronidazole.

Complications of PID include perihepatitis (Fitz-Hugh Curtis Syndrome), which occurs in around 10% of cases and is characterized by right upper quadrant pain that may be confused with cholecystitis. PID can also lead to infertility, with the risk as high as 10-20% after a single episode, chronic pelvic pain, and ectopic pregnancy. In mild cases of PID, intrauterine contraceptive devices may be left in, but recent guidelines suggest that removal of the IUD should be considered for better short-term clinical outcomes. Understanding PID and its potential complications is crucial for early diagnosis and effective management.

The use of combined oral contraceptive pill is associated with a reduced risk of endometrial cancer.

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. Progestogen 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.

Induction of Labour: Reasons, Methods, and Complications

Induction of labour is a medical process that involves starting labour artificially. It is necessary in about 20% of pregnancies due to various reasons such as prolonged pregnancy, prelabour premature rupture of the membranes, diabetes, pre-eclampsia, and rhesus incompatibility. The Bishop score is used to assess whether induction of labour is required, which takes into account cervical position, consistency, effacement, dilation, and fetal station. A score of less than 5 indicates that labour is unlikely to start without induction, while a score of 8 or more indicates that the cervix is ripe and there is a high chance of spontaneous labour or response to interventions made to induce labour.

There are several methods of induction of labour, including membrane sweep, vaginal prostaglandin E2, maternal oxytocin infusion, amniotomy, and cervical ripening balloon. Membrane sweeping involves separating the chorionic membrane from the decidua by rotating the examining finger against the wall of the uterus. Vaginal prostaglandin E2 is the preferred method of induction of labour, unless there are specific clinical reasons for not using it. Uterine hyperstimulation is the main complication of induction of labour, which refers to prolonged and frequent uterine contractions that can cause fetal hypoxemia and acidemia. In rare cases, uterine rupture may occur, which requires removing the vaginal prostaglandins and stopping the oxytocin infusion if one has been started, and tocolysis with terbutaline.

Ectopic pregnancy presents with amenorrhoea, abdominal pain, vaginal bleeding, and shoulder tip pain indicating peritoneal bleeding.

Understanding Ectopic Pregnancy

Ectopic pregnancy occurs when a fertilized egg implants outside the uterus. This condition is characterized by lower abdominal pain and vaginal bleeding, typically occurring 6-8 weeks after the start of the last period. The pain is usually constant and may be felt on one side of the abdomen due to tubal spasm. Vaginal bleeding is usually less than a normal period and may be dark brown in color. Other symptoms may include shoulder tip pain, pain on defecation/urination, dizziness, fainting, or syncope. Breast tenderness may also be reported.

During examination, abdominal tenderness and cervical excitation may be observed. However, it is not recommended to examine for an adnexal mass due to the risk of rupturing the pregnancy. Instead, a pelvic examination to check for cervical excitation is recommended. In cases of pregnancy of unknown location, serum bHCG levels >1,500 may indicate an ectopic pregnancy. It is important to seek medical attention immediately if ectopic pregnancy is suspected as it can be life-threatening.

Levonorgestrel is the correct choice, as the patient has expressed reluctance to try a different form of contraception. It is important to prioritize pregnancy prevention while also discussing the benefits of long-acting reversible contraception and allowing the patient time to consider it. While ulipristal and levonorgestrel are both oral options, ulipristal should be used cautiously in patients with severe asthma. As the patient is still within the 72-hour window for levonorgestrel use and has missed two doses of her oral contraceptive pill, levonorgestrel is the preferred option.

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.

Liver Disorders in Pregnancy: Differential Diagnosis

During pregnancy, various liver disorders can occur, each with its own set of symptoms and potential complications. Here are some of the most common liver disorders that can occur during pregnancy and their distinguishing features:

1. Hyperemesis gravidarum: This is the most severe form of nausea and vomiting in pregnancy, which can lead to weight loss, dehydration, and electrolyte imbalances. It is characterised by persistent nausea and vomiting, and may require hospitalisation.

2. Acute fatty liver of pregnancy: This is a rare but serious complication that can occur in the third trimester. It is characterised by microvesicular steatosis in the liver, which can lead to liver insufficiency. Symptoms include malaise, nausea and vomiting, right upper quadrant and epigastric pain, and acute renal failure.

3. Intrahepatic cholestasis of pregnancy: This is the most common pregnancy-related liver disorder, characterised by generalised itching, particularly in the palms and soles, and jaundice. It is caused by hormonal changes and can lead to fetal complications if not treated promptly.

4. Pre-eclampsia: This is a disorder of widespread vascular malfunction that occurs after 20 weeks of gestation. It is characterised by hypertension and proteinuria, with or without oedema.

5. Biliary tract disease: This is a broad spectrum of disorders ranging from asymptomatic gallstones to cholecystitis and choledocholithiasis. Symptoms include biliary colic, inflammation of the gall bladder wall, and obstruction of the common bile duct.

It is important to differentiate between these liver disorders in pregnancy, as each requires a different approach to management and treatment. Consultation with a healthcare provider is recommended for proper diagnosis and management.

For patients with active hormone-responsive breast cancer, hormonal methods like HRT and tibolone are not recommended. Instead, non-hormonal methods like selective serotonin reuptake inhibitors and venlafaxine may be used to alleviate vasomotor symptoms of menopause. Topical estrogen can also be used to alleviate symptoms of vaginal atrophy, but it does not help with vasomotor symptoms. COCP is not a suitable treatment for menopausal symptoms.

Managing Menopause: Lifestyle Modifications, Hormone Replacement Therapy, and Non-Hormone Replacement Therapy

Menopause is a natural biological process that marks the end of a woman’s reproductive years. It is diagnosed when a woman has not had a period for 12 consecutive months. Menopausal symptoms are common and can last for up to 7 years, with varying degrees of severity and duration. The management of menopause can be divided into three categories: lifestyle modifications, hormone replacement therapy (HRT), and non-hormone replacement therapy.

Lifestyle modifications can help manage menopausal symptoms such as hot flushes, sleep disturbance, mood changes, and cognitive symptoms. Regular exercise, weight loss, stress reduction, and good sleep hygiene are recommended. For women who cannot or do not want to take HRT, non-hormonal treatments such as fluoxetine, citalopram, or venlafaxine for vasomotor symptoms, vaginal lubricants or moisturizers for vaginal dryness, and cognitive behavior therapy or antidepressants for psychological symptoms can be prescribed.

HRT is a treatment option for women with moderate to severe menopausal symptoms. However, it is contraindicated in women with current or past breast cancer, any estrogen-sensitive cancer, undiagnosed vaginal bleeding, or untreated endometrial hyperplasia. HRT brings certain risks, including venous thromboembolism, stroke, coronary heart disease, breast cancer, and ovarian cancer. Women should be advised of these risks and the fact that symptoms typically last for 2-5 years.

When stopping HRT, it is important to gradually reduce the dosage to limit recurrence of symptoms in the short term. However, in the long term, there is no difference in symptom control. Women who experience ineffective treatment, ongoing side effects, or unexplained bleeding should be referred to secondary care. Overall, managing menopause requires a personalized approach that takes into account a woman’s medical history, preferences, and individual symptoms.

It is essential to treat the candidal infection by administering miconazole cream to both the mother and child. The cream should be applied to the nipple after feeding and the infant’s oral mucosa. Breastfeeding should continue during the treatment period. Additionally, the mother should be educated on maintaining good hand hygiene after changing the baby’s nappy and sterilizing any objects that the baby puts in their mouth, such as dummies and teats. This information is provided by NICE CKS.

Breastfeeding Problems and Their Management

Breastfeeding is a natural process, but it can come with its own set of challenges. Some of the minor problems that breastfeeding mothers may encounter include frequent feeding, nipple pain, blocked ducts, and nipple candidiasis. These issues can be managed by seeking advice on proper positioning, trying breast massage, and using appropriate medication.

Mastitis is a more serious problem that affects around 1 in 10 breastfeeding women. It is characterized by symptoms such as fever, nipple fissure, and persistent pain. Treatment involves the use of antibiotics, such as flucloxacillin, for 10-14 days. Breastfeeding or expressing milk should continue during treatment to prevent complications such as breast abscess.

Breast engorgement is another common problem that causes breast pain in breastfeeding women. It occurs in the first few days after birth and affects both breasts. Hand expression of milk can help relieve the discomfort of engorgement. Raynaud’s disease of the nipple is a less common problem that causes nipple pain and blanching. Treatment involves minimizing exposure to cold, using heat packs, and avoiding caffeine and smoking.

If a breastfed baby loses more than 10% of their birth weight in the first week of life, it may be a sign of poor weight gain. This should prompt consideration of the above breastfeeding problems and an expert review of feeding. Monitoring of weight should continue until weight gain is satisfactory.

When it comes to providing contraception to young people, there are legal and ethical considerations to take into account. In the UK, the age of consent for sexual activity is 16 years, but practitioners may still offer advice and contraception to young people they deem competent. The Fraser Guidelines are often used to assess a young person’s competence. Children under the age of 13 are considered unable to consent to sexual intercourse, and consultations regarding this age group should trigger child protection measures automatically.

It’s important to advise young people to have STI tests 2 and 12 weeks after an incident of unprotected sexual intercourse. Long-acting reversible contraceptive methods (LARCs) are often the best choice for young people, as they may be less reliable in remembering to take medication. However, there are concerns about the effect of progesterone-only injections (Depo-provera) on bone mineral density, and the UKMEC category of the IUS and IUD is 2 for women under the age of 20 years, meaning they may not be the best choice. The progesterone-only implant (Nexplanon) is therefore the LARC of choice for young people.

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.

The Mirena coil is a contraceptive method that reduces the duration and intensity of periods and can be used for an extended period.

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.

Understanding Genital Warts

Genital warts, also known as condylomata accuminata, are a common reason for visits to genitourinary clinics. These warts are caused by various types of the human papillomavirus (HPV), with types 6 and 11 being the most common culprits. It is important to note that HPV, particularly types 16, 18, and 33, can increase the risk of cervical cancer.

The warts themselves are small, fleshy protrusions that are typically 2-5mm in size and may be slightly pigmented. They can cause discomfort, itching, and even bleeding. Treatment options for genital warts include topical podophyllum or cryotherapy, depending on the location and type of lesion. Topical agents are generally used for multiple, non-keratinised warts, while solitary, keratinised warts respond better to cryotherapy. Imiquimod, a topical cream, is often used as a second-line treatment. It is important to note that genital warts can be resistant to treatment, and recurrence is common. However, most anogenital HPV infections clear up on their own within 1-2 years without intervention.

The combined oral contraceptive pill is associated with a higher likelihood of developing breast and cervical cancer, but it can also provide protection against ovarian and endometrial cancer.

Pros and Cons of the Combined Oral Contraceptive Pill

The combined oral contraceptive pill is a highly effective method of birth control with a failure rate of less than 1 per 100 woman years. It does not interfere with sexual activity and its contraceptive effects are reversible upon stopping. Additionally, it can make periods regular, lighter, and less painful, and may reduce the risk of ovarian, endometrial, and colorectal cancer. It may also protect against pelvic inflammatory disease, ovarian cysts, benign breast disease, and acne vulgaris.

However, there are also some disadvantages to the combined oral contraceptive pill. One of the main issues is that people may forget to take it, which can reduce its effectiveness. It also offers no protection against sexually transmitted infections. There is an increased risk of venous thromboembolic disease, breast and cervical cancer, stroke, and ischaemic heart disease, especially in smokers. Temporary side-effects such as headache, nausea, and breast tenderness may also be experienced.

It is important to weigh the pros and cons of the combined oral contraceptive pill before deciding if it is the right method of birth control for you. While some users report weight gain while taking the pill, a Cochrane review did not support a causal relationship. Overall, the combined oral contraceptive pill can be an effective and convenient method of birth control, but it is important to discuss any concerns or potential risks with a healthcare provider.
