Shingles Vaccine Availability by Age

The shingles vaccine is available to individuals at different ages depending on their stage of life. Those who are 70 or 78-years old are eligible to receive the vaccine. However, it is not routinely offered to patients who are in their 50’s or 60’s. The vaccine is not part of the routine childhood immunisation schedule and is only available to NHS patients in their 70’s. It is not offered to individuals who are 80 or older, as it appears to be less effective in this age group. It is important to consult with a healthcare provider to determine the appropriate age to receive the shingles vaccine.

Differential Diagnosis for a Patient with Low Mood and Renal Stones

Primary Hyperparathyroidism:
This condition can cause hypercalcemia, which may present as renal stones, osteoporosis, arthritis, nausea and vomiting, peptic ulcer disease, constipation, polyuria, depression, memory loss, and delirium.

Hyperthyroidism:
Hyperthyroidism may present with restlessness, irritability, insomnia, tremor, palpitations, weight loss, sweating, heat intolerance, diarrhea, oligomenorrhea, hair thinning, and muscle weakness. Graves’ disease may also cause a goiter and thyroid eye disease, presenting as proptosis, dry eyes, periorbital edema, and lagophthalmos.

Hypothyroidism:
Typical features of hypothyroidism include dry skin, brittle and diminished hair, lethargy, cold intolerance, dull or blank expression, puffy eyelids, and weight gain. Patients may also experience cerebellar ataxia, ascites, non-pitting edema of the hands and feet, and congestive cardiac failure.

Pseudopseudohypoparathyroidism:
This condition may present with short fourth and fifth metacarpals, round face, short stature, basal ganglia calcification, and decreased IQ.

Secondary Hyperparathyroidism:
This condition may present with signs and symptoms of hypocalcemia, including perioral paresthesia, seizures, spasms, anxiety, increased smooth muscle tone, disorientation, dermatitis, impetigo herpetiformis, cataracts, Chvostek’s sign, and long Q–T interval.

Differential Diagnosis for a Patient with Low Mood and Renal Stones

Peripheral neuropathy is a known side effect of Vincristine. Additionally, bladder atony may cause urinary hesitancy.

Cytotoxic agents are drugs that are used to kill cancer cells. There are several types of cytotoxic agents, each with their own mechanism of action and adverse effects. Alkylating agents, such as cyclophosphamide, work by causing cross-linking in DNA. However, they can also cause haemorrhagic cystitis, myelosuppression, and transitional cell carcinoma. Cytotoxic antibiotics, like bleomycin, degrade preformed DNA and can lead to lung fibrosis. Anthracyclines, such as doxorubicin, stabilize the DNA-topoisomerase II complex and inhibit DNA and RNA synthesis, but can also cause cardiomyopathy. Antimetabolites, like methotrexate, inhibit dihydrofolate reductase and thymidylate synthesis, leading to myelosuppression, mucositis, liver fibrosis, and lung fibrosis. Fluorouracil (5-FU) is a pyrimidine analogue that induces cell cycle arrest and apoptosis by blocking thymidylate synthase, but can also cause myelosuppression, mucositis, and dermatitis. Cytarabine is a pyrimidine antagonist that interferes with DNA synthesis specifically at the S-phase of the cell cycle and inhibits DNA polymerase, but can also cause myelosuppression and ataxia. Drugs that act on microtubules, like vincristine and vinblastine, inhibit the formation of microtubules and can cause peripheral neuropathy, paralytic ileus, and myelosuppression. Docetaxel prevents microtubule depolymerisation and disassembly, decreasing free tubulin, but can also cause neutropaenia. Topoisomerase inhibitors, like irinotecan, inhibit topoisomerase I which prevents relaxation of supercoiled DNA, but can also cause myelosuppression. Other cytotoxic drugs, such as cisplatin, cause cross-linking in DNA and can lead to ototoxicity, peripheral neuropathy, and hypomagnesaemia. Hydroxyurea (hydroxycarbamide) inhibits ribonucleotide reductase, decreasing DNA synthesis, but can also cause myelosuppression.

Withholding fluids for 2 hours before bedtime is not recommended as part of enuresis management. While limiting fluid intake throughout the day and before bedtime, especially caffeinated drinks, is advised, completely withholding fluids is not recommended. Referring the patient for sleep studies is not the most appropriate management at this stage, although other conditions that can worsen enuresis, such as sleep-disordered breathing, should be considered. Desmopressin, an analogue of anti-diuretic hormone (ADH), is not indicated at this stage and is only used when general advice and enuresis alarm have failed. The primary goal of management is to achieve dry nights at follow-up.

Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.

When managing bedwetting, it’s important to look for any underlying causes or triggers, such as constipation, diabetes mellitus, or recent onset UTIs. General advice includes monitoring fluid intake and encouraging regular toileting patterns, such as emptying the bladder before sleep. Reward systems, like star charts, can also be helpful, but should be given for agreed behavior rather than dry nights.

The first-line treatment for bedwetting is an enuresis alarm, which has a high success rate. These alarms have sensor pads that detect wetness and wake the child up to use the toilet. If short-term control is needed, such as for sleepovers, or if the alarm is ineffective or not acceptable to the family, desmopressin may be prescribed. Overall, managing bedwetting involves identifying any underlying causes and implementing strategies to promote continence.

When a child has bronchiolitis, it is common for them to have a low-grade fever. However, if the child has a high fever (over 39°C) and/or persistently focal crackles, it may indicate a diagnosis of pneumonia.

Bronchiolitis is a condition where the bronchioles become inflamed, and it is most commonly caused by respiratory syncytial virus (RSV). This virus is responsible for 75-80% of cases, with other causes including mycoplasma and adenoviruses. Bronchiolitis is most prevalent in infants under one year old, with 90% of cases occurring in those aged 1-9 months. The condition is more serious in premature babies, those with congenital heart disease or cystic fibrosis. Symptoms include coryzal symptoms, dry cough, increasing breathlessness, and wheezing. Hospital admission is often necessary due to feeding difficulties associated with increasing dyspnoea.

Immediate referral is recommended if the child has apnoea, looks seriously unwell, has severe respiratory distress, central cyanosis, or persistent oxygen saturation of less than 92% when breathing air. Clinicians should consider referral if the child has a respiratory rate of over 60 breaths/minute, difficulty with breastfeeding or inadequate oral fluid intake, or clinical dehydration. Immunofluorescence of nasopharyngeal secretions may show RSV, and management is largely supportive. Humidified oxygen is given via a head box if oxygen saturations are persistently low, and nasogastric feeding may be necessary if children cannot take enough fluid/feed by mouth. Suction may also be used for excessive upper airway secretions. NICE released guidelines on bronchiolitis in 2015 for more information.

Non-typhi salmonella (NTS) is known to cause blood and bone infections, particularly in children with sickle cell disease and malaria. The exact reason for this susceptibility is not fully understood, but it may be due to the bacteria’s affinity for iron, which is made available through haemolysis. Other bacteria such as E.coli and P. aeruginosa are not commonly associated with sickle cell disease, and Staphylococcus aureus is a gram-positive coccus. Aplastic anaemia and parvovirus can be ruled out as causes, as the child’s haemoglobin level is normal and parvovirus does not cause osteomyelitis.

Understanding Osteomyelitis: Types, Causes, and Treatment

Osteomyelitis is a bone infection that can be classified into two types: haematogenous and non-haematogenous. Haematogenous osteomyelitis is caused by bacteria that enter the bloodstream and is usually monomicrobial. It is more common in children, with vertebral osteomyelitis being the most common form in adults. Risk factors include sickle cell anaemia, intravenous drug use, immunosuppression, and infective endocarditis. On the other hand, non-haematogenous osteomyelitis results from the spread of infection from adjacent soft tissues or direct injury to the bone. It is often polymicrobial and more common in adults, with risk factors such as diabetic foot ulcers, pressure sores, diabetes mellitus, and peripheral arterial disease.

Staphylococcus aureus is the most common cause of osteomyelitis, except in patients with sickle-cell anaemia where Salmonella species predominate. To diagnose osteomyelitis, MRI is the imaging modality of choice, with a sensitivity of 90-100%. Treatment for osteomyelitis involves a six-week course of flucloxacillin. Clindamycin is an alternative for patients who are allergic to penicillin.

In summary, osteomyelitis is a bone infection that can be caused by bacteria entering the bloodstream or spreading from adjacent soft tissues or direct injury to the bone. It is more common in children and adults with certain risk factors. Staphylococcus aureus is the most common cause, and MRI is the preferred imaging modality for diagnosis. Treatment involves a six-week course of flucloxacillin or clindamycin for penicillin-allergic patients.

Heart Failure Medications: Uses and Recommendations

Heart failure is a serious condition that requires proper management and treatment. There are several medications available for heart failure, each with its own specific uses and recommendations.

Enalapril is an ACE inhibitor that works by reducing levels of angiotensin II, a potent vasoconstrictor, resulting in reduced vasoconstriction and a reduction in left ventricular afterload. It is recommended as a first-line treatment for all patients with heart failure due to left ventricular systolic dysfunction.

Digoxin is recommended for worsening or severe heart failure due to left ventricular systolic dysfunction despite first- and second-line treatment for heart failure.

Aspirin should be prescribed for patients with heart failure and atherosclerotic arterial disease, including coronary heart disease. It is not useful in monotherapy for the treatment of heart failure.

Furosemide is a diuretic that is routinely used for the relief of congestive symptoms and fluid retention in patients with heart failure. It should be titrated according to need after the initiation of subsequent heart failure therapies.

Spironolactone is an aldosterone antagonist that forms the second-line treatment in patients with heart failure. It is important to closely monitor potassium and creatinine levels and the estimated glomerular filtration rate (eGFR). Specialist advice should be sought if the patient develops hyperkalaemia or renal function deteriorates.

In summary, the appropriate medication for heart failure depends on the individual patient’s condition and needs. It is important to consult with a healthcare professional for proper diagnosis and treatment.

Aspirating breast cysts is necessary due to the potential risk of breast cancer, particularly in younger women. Merely monitoring the cysts with ultrasound or mammogram without aspiration is not a suitable approach. There is no need for wide local excision at this point. Providing false reassurance to the patient is not advisable.

Benign breast lesions have different features and treatments. Fibroadenomas are firm, mobile lumps that develop from a whole lobule and usually do not increase the risk of malignancy. Breast cysts are smooth, discrete lumps that may be aspirated, but blood-stained or persistently refilling cysts should be biopsied or excised. Sclerosing adenosis, radial scars, and complex sclerosing lesions cause mammographic changes that may mimic carcinoma, but do not increase the risk of malignancy. Epithelial hyperplasia may present as general lumpiness or a discrete lump, and atypical features and family history of breast cancer increase the risk of malignancy. Fat necrosis may mimic carcinoma and requires imaging and core biopsy. Duct papillomas usually present with nipple discharge and may require microdochectomy.

The eGFR (estimated glomerular filtration rate) is determined by several variables, including CAGE, which stands for Creatinine, Age, Gender, and Ethnicity.

Understanding Chronic Kidney Disease: eGFR and Classification

Chronic kidney disease (CKD) is a condition that affects the kidneys’ ability to filter waste products from the blood. Serum creatinine, a commonly used measure of kidney function, may not provide an accurate estimate due to differences in muscle mass. To address this, formulas such as the Modification of Diet in Renal Disease (MDRD) equation were developed to estimate the glomerular filtration rate (eGFR). The MDRD equation takes into account variables such as serum creatinine, age, gender, and ethnicity.

It is important to note that certain factors may affect the accuracy of eGFR results, such as pregnancy, muscle mass, and recent consumption of red meat. CKD can be classified based on eGFR, with stage 1 indicating a GFR greater than 90 ml/min with some sign of kidney damage on other tests. Stage 2 indicates a GFR of 60-90 ml/min with some sign of kidney damage, while stage 3a and 3b indicate a moderate reduction in kidney function with GFR ranges of 45-59 ml/min and 30-44 ml/min, respectively. Stage 4 indicates a severe reduction in kidney function with a GFR range of 15-29 ml/min, while stage 5 indicates established kidney failure with a GFR less than 15 ml/min, which may require dialysis or a kidney transplant. It is important to note that if all kidney tests are normal, there is no CKD.

Interpreting Glucose Tolerance Test Results in Insulin-Dependent Diabetes

Glucose tolerance tests are commonly used to diagnose and monitor diabetes. In insulin-dependent diabetes, the results of these tests can provide valuable information about the patient’s glucose metabolism. Here are some key points to consider when interpreting glucose tolerance test results in insulin-dependent diabetes:

– A peak of plasma glucose occurring between 1 and 2 hours that stays high: In insulin-dependent diabetes, the plasma glucose remains elevated throughout the 4 hours of the test. This is in contrast to normal individuals, who typically have a sharper and earlier peak that returns to basal levels.
– An ‘overshoot’ in the decline of plasma glucose at 3.5 hours: This phenomenon is seen in normal individuals but not in insulin-dependent diabetics.
– A plasma glucose level of 4 mmol/l at zero time: This is unlikely in diabetic patients, who typically have high basal glucose levels.
– A glucose concentration of 5.2 mmol/l at 4 hours: In insulin-dependent diabetes, the plasma glucose remains elevated throughout the 4 hours of the test.
– A low haemoglobin A1c (HbA1c): If the patient has been suffering from diabetes for some time without treatment, the HbA1c would likely be elevated rather than low.

Overall, glucose tolerance tests can provide valuable insights into the glucose metabolism of insulin-dependent diabetics. By understanding the nuances of these test results, healthcare providers can better diagnose and manage this chronic condition.

Fragile X is a condition characterized by learning difficulties, macrocephaly, large ears, and macro-orchidism in young boys.

Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions. Edward’s syndrome, also known as trisomy 18, is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. Fragile X syndrome is characterized by learning difficulties, macrocephaly, long face, large ears, and macro-orchidism. Noonan syndrome is characterized by a webbed neck, pectus excavatum, short stature, and pulmonary stenosis. Pierre-Robin syndrome is characterized by micrognathia, posterior displacement of the tongue, and cleft palate. Prader-Willi syndrome is characterized by hypotonia, hypogonadism, and obesity. William’s syndrome is characterized by short stature, learning difficulties, friendly, extrovert personality, and transient neonatal hypercalcaemia. Cri du chat syndrome, also known as chromosome 5p deletion syndrome, is characterized by a characteristic cry, feeding difficulties and poor weight gain, learning difficulties, microcephaly and micrognathism, and hypertelorism. It is important to note that Treacher-Collins syndrome is similar to Pierre-Robin syndrome, but it is autosomal dominant and usually has a family history of similar problems.

For the treatment of menorrhagia, the first-line option would be the intrauterine system. Specifically, the Mirena, which contains levonorgestrel, is highly effective in treating menorrhagia and also serves as a long-acting reversible contraceptive. While the combined oral contraceptive pill, tranexamic acid, and mefenamic acid may provide relief from symptoms, they are not the preferred initial treatment. On the other hand, the intrauterine device would not be suitable for addressing this patient’s menorrhagia.

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.

The British Thoracic Society recommends using macrolide antibiotics like clarithromycin or erythromycin as empirical treatment for community-acquired pneumonia in both children and adults if first-line β-lactam antibiotics are ineffective or in cases of severe disease. Atypical infections are often diagnosed late in the illness, making early targeted therapy difficult. M. pneumoniae pneumonia tends to occur in outbreaks in the UK, so being aware of these outbreaks can help guide treatment. Benzylpenicillin is used to treat various infections, including throat infections, otitis media, and cellulitis. Cefuroxime is a broad-spectrum antibiotic used to treat susceptible infections caused by both Gram-positive and Gram-negative bacteria, including respiratory tract infections, Lyme disease, and urinary tract infections. Rifampicin is used in combination with other drugs to treat brucellosis, Legionnaires’ disease, serious staphylococcal infections, endocarditis, and tuberculosis. Co-trimoxazole is used to treat Pneumocystis jirovecii pneumonia and can be administered orally for mild-to-moderate pneumonia or intravenously in dual therapy with steroids for severe pneumonia. It can also be used for PCP prophylaxis in HIV-positive patients, with primary prophylaxis recommended for those with a CD4 count of <£200 and secondary prophylaxis essential after the first infection.

Conditions that are X-linked recessive do not show transmission from male to male.

Understanding X-Linked Recessive Inheritance

X-linked recessive inheritance is a genetic pattern where only males are affected, except in rare cases such as Turner’s syndrome. This type of inheritance is transmitted by heterozygote females, who are carriers of the gene mutation. Male-to-male transmission is not observed in X-linked recessive disorders. Affected males can only have unaffected sons and carrier daughters.

If a female carrier has children, each male child has a 50% chance of being affected, while each female child has a 50% chance of being a carrier. It is important to note that the possibility of an affected father having children with a heterozygous female carrier is generally rare. However, in some Afro-Caribbean communities, G6PD deficiency is relatively common, and homozygous females with clinical manifestations of the enzyme defect are observed.

In summary, X-linked recessive inheritance is a genetic pattern that affects only males and is transmitted by female carriers. Understanding this pattern is crucial in predicting the likelihood of passing on genetic disorders to future generations.

The patient’s symptoms and medical history suggest a diagnosis of lichen planus, a skin condition with an unknown cause that is likely immune-mediated. The rash is typically itchy and appears as papules with a shiny, purplish color in areas such as the palms, soles, genitalia, and flexor surfaces of the arms. The rash often has a polygonal shape and may have white lines known as Wickham’s striae. Over time, the papules flatten and are replaced by hyperpigmentation. Oral involvement is common, with a white-lace pattern on the buccal mucosa. Management usually involves topical steroids, but more severe cases may require oral steroids or immunosuppressants. Atopic eczema, irritant eczema, molluscum contagiosum, and psoriasis are different skin conditions that do not fit the patient’s symptoms.

Individuals with heart failure and an ejection fraction of 40% or lower should be prescribed an ACE inhibitor, unless there are contraindications or intolerance. This is supported by numerous clinical trials that have shown their efficacy in reducing hospital admissions and mortality rates. The dosage should be started low and gradually increased until the target dose or the highest tolerated dose is achieved, with regular monitoring of renal function and serum electrolytes.

Loop Diuretics: Mechanism of Action and Indications

Loop diuretics, such as furosemide and bumetanide, are medications that inhibit the Na-K-Cl cotransporter (NKCC) in the thick ascending limb of the loop of Henle. This reduces the absorption of NaCl and increases the excretion of water and electrolytes, making them effective in treating conditions such as heart failure and resistant hypertension. Loop diuretics act on NKCC2, which is more prevalent in the kidneys.

As loop diuretics work on the apical membrane, they must first be filtered into the tubules by the glomerulus before they can have an effect. This means that patients with poor renal function may require higher doses to achieve a sufficient concentration within the tubules.

Loop diuretics are commonly used in the treatment of heart failure, both acutely (usually intravenously) and chronically (usually orally). They are also effective in treating resistant hypertension, particularly in patients with renal impairment.

However, loop diuretics can have adverse effects, including hypotension, hyponatremia, hypokalemia, hypomagnesemia, hypochloremic alkalosis, ototoxicity, hypocalcemia, renal impairment (from dehydration and direct toxic effect), hyperglycemia (less common than with thiazides), and gout.

In summary, loop diuretics are effective medications for treating heart failure and resistant hypertension, but their use should be carefully monitored due to potential adverse effects. Patients with poor renal function may require higher doses to achieve therapeutic effects.

Managing Asthma in Children: NICE Guidelines

Asthma management in children has been updated by NICE in 2017, following the 2016 BTS guidelines. The new guidelines for children aged 5-16 are similar to those for adults, with a stepwise approach for treatment. For newly-diagnosed asthma, short-acting beta agonist (SABA) is recommended. If symptoms persist, a combination of SABA and paediatric low-dose inhaled corticosteroid (ICS) is used. Leukotriene receptor antagonist (LTRA) is added if symptoms still persist, followed by long-acting beta agonist (LABA) if necessary. Maintenance and reliever therapy (MART) is used as a combination of ICS and LABA for daily maintenance therapy and symptom relief. For children under 5 years old, clinical judgement plays a greater role in diagnosis. The stepwise approach is similar to that for older children, with an 8-week trial of paediatric moderate-dose ICS before adding LTRA. If symptoms persist, referral to a paediatric asthma specialist is recommended.

It should be noted that NICE does not recommend changing treatment for well-controlled asthma patients simply to adhere to the latest guidelines. The definitions of low, moderate, and high-dose ICS have also changed, with different definitions for adults and children. For children, <= 200 micrograms budesonide or equivalent is considered a paediatric low dose, 200-400 micrograms is a moderate dose, and > 400 micrograms is a high dose. Overall, the new NICE guidelines provide a clear and concise approach to managing asthma in children.

Regular monitoring of renal function and electrolytes is necessary for both Ramipril, an ACE inhibitor, and Candesartan, an angiotensin 2 receptor blocker.

Understanding Calcium Channel Blockers

Calcium channel blockers are medications primarily used to manage cardiovascular diseases. These blockers target voltage-gated calcium channels present in myocardial cells, cells of the conduction system, and vascular smooth muscle cells. The different types of calcium channel blockers have varying effects on these three areas, making it crucial to differentiate their uses and actions.

Verapamil is an example of a calcium channel blocker used to manage angina, hypertension, and arrhythmias. However, it is highly negatively inotropic and should not be given with beta-blockers as it may cause heart block. Verapamil may also cause side effects such as heart failure, constipation, hypotension, bradycardia, and flushing.

Diltiazem is another calcium channel blocker used to manage angina and hypertension. It is less negatively inotropic than verapamil, but caution should still be exercised when patients have heart failure or are taking beta-blockers. Diltiazem may cause side effects such as hypotension, bradycardia, heart failure, and ankle swelling.

On the other hand, dihydropyridines such as nifedipine, amlodipine, and felodipine are calcium channel blockers used to manage hypertension, angina, and Raynaud’s. These blockers affect the peripheral vascular smooth muscle more than the myocardium, resulting in no worsening of heart failure but may cause ankle swelling. Shorter-acting dihydropyridines such as nifedipine may cause peripheral vasodilation, resulting in reflex tachycardia and side effects such as flushing, headache, and ankle swelling.

In summary, understanding the different types of calcium channel blockers and their effects on the body is crucial in managing cardiovascular diseases. It is also important to note the potential side effects and cautions when prescribing these medications.

Vaginal PGE2 is the preferred method of induction of labour, with other options such as emergency caesarean section, maternal oxytocin infusion, amniotomy, and cervical ripening balloon being considered only in certain situations. Women undergoing vaginal PGE2 should be aware of the risk of uterine hyperstimulation and may require additional analgesia. The cervix should be reassessed before considering oxytocin infusion. Amniotomy may be used in combination with oxytocin infusion in patients with a ripe cervix. Cervical ripening balloon should not be used as the primary method for induction of labour due to its potential pain, bleeding, and infection risks.

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.

The use of Tamoxifen is limited to pre-menopausal women, and there is a continuing discussion regarding the duration of therapy, whether it should be for 5 years or more.

Breast cancer management varies depending on the stage of the cancer, type of tumor, and patient’s medical history. Treatment options may include surgery, radiotherapy, hormone therapy, biological therapy, and chemotherapy. Surgery is typically the first option for most patients, except for elderly patients with metastatic disease who may benefit more from hormonal therapy. Prior to surgery, an axillary ultrasound is recommended for patients without palpable axillary lymphadenopathy, while those with clinically palpable lymphadenopathy require axillary node clearance. The type of surgery offered depends on various factors, such as tumor size, location, and type. Breast reconstruction is also an option for patients who have undergone a mastectomy.

Radiotherapy is recommended after a wide-local excision to reduce the risk of recurrence, while mastectomy patients may receive radiotherapy for T3-T4 tumors or those with four or more positive axillary nodes. Hormonal therapy is offered if tumors are positive for hormone receptors, with tamoxifen being used in pre- and peri-menopausal women and aromatase inhibitors like anastrozole in post-menopausal women. Tamoxifen may increase the risk of endometrial cancer, venous thromboembolism, and menopausal symptoms. Biological therapy, such as trastuzumab, is used for HER2-positive tumors but cannot be used in patients with a history of heart disorders. Chemotherapy may be used before or after surgery, depending on the stage of the tumor and the presence of axillary node disease. FEC-D is commonly used in the latter case.
