If a foetal heartbeat is detected on ultrasound in the case of an ectopic pregnancy, surgical management is necessary, and the appropriate procedure is a salpingectomy. This is the recommended course of action for a patient with no significant medical history and both fallopian tubes. Expectant management is not suitable in this scenario, as the foetal heartbeat is visible on ultrasound. Medical management with methotrexate is also not an option due to the foetal heartbeat, and mifepristone is not used for ectopic pregnancies.

Ectopic pregnancy is a serious condition that requires prompt investigation and management. Women who are stable are typically investigated and managed in an early pregnancy assessment unit, while those who are unstable should be referred to the emergency department. The investigation of choice for ectopic pregnancy is a transvaginal ultrasound, which will confirm the presence of a positive pregnancy test.

There are three ways to manage ectopic pregnancies: expectant management, medical management, and surgical management. The choice of management will depend on various criteria, such as the size of the ectopic pregnancy, whether it is ruptured or not, and the patient’s symptoms and hCG levels. Expectant management involves closely monitoring the patient over 48 hours, while medical management involves giving the patient methotrexate and requires follow-up. Surgical management can involve salpingectomy or salpingotomy, depending on the patient’s risk factors for infertility.

Salpingectomy is the first-line treatment for women with no other risk factors for infertility, while salpingotomy should be considered for women with contralateral tube damage. However, around 1 in 5 women who undergo a salpingotomy require further treatment, such as methotrexate and/or a salpingectomy. It is important to carefully consider the patient’s individual circumstances and make a decision that will provide the best possible outcome.

When it comes to managing scalp psoriasis, the approach is slightly different from managing plaque psoriasis. The first-line treatment typically involves using potent corticosteroids topically. Among the options, betamethasone valerate is the best answer as it is a potent corticosteroid that can be prescribed as a shampoo or mousse for easier application. For severe and extensive psoriasis, oral methotrexate may be recommended, but this is not applicable to the patient in question. Phototherapy is also an option for extensive psoriasis, but not for this patient who has well-controlled chronic plaque psoriasis. If no improvement is seen after 8 weeks of using a topical potent corticosteroid, second-line treatment may involve using topical vitamin D.

NICE recommends a step-wise approach for chronic plaque psoriasis, starting with regular emollients and then using a potent corticosteroid and vitamin D analogue separately, followed by a vitamin D analogue twice daily, and then a potent corticosteroid or coal tar preparation if there is no improvement. Phototherapy, systemic therapy, and topical treatments are also options for management. Topical steroids should be used cautiously and vitamin D analogues may be used long-term. Dithranol and coal tar have adverse effects but can be effective.

It is essential to refer patients suspected of having AMD to ophthalmology urgently within 1 week for a formal diagnosis. This is because if the diagnosis is wet AMD, anti-VEGF injections can be administered, which will improve the patient’s long-term visual outcome. Even if drusen is present, which is more indicative of dry AMD, an urgent referral should still be made within 1 week. Delaying the referral for a month will postpone the formal diagnosis and treatment commencement for the patient. While multi-vitamins may be beneficial for dry AMD, it is not the next step in management. Atorvastatin is used to lower blood cholesterol levels and is not effective in treating drusen.

Age-related macular degeneration (ARMD) is a common cause of blindness in the UK, characterized by the degeneration of the central retina (macula) and the formation of drusen. It is more prevalent in females and is strongly associated with advancing age, smoking, family history, and conditions that increase the risk of ischaemic cardiovascular disease. ARMD can be classified into two forms: dry and wet. Dry ARMD is more common and is characterized by drusen, while wet ARMD is characterized by choroidal neovascularisation and carries a worse prognosis. Clinical features of ARMD include subacute onset of visual loss, difficulties in dark adaptation, and visual disturbances such as photopsia and glare.

To diagnose ARMD, slit-lamp microscopy and color fundus photography are used to identify any pigmentary, exudative, or haemorrhagic changes affecting the retina. Fluorescein angiography and indocyanine green angiography may also be used to visualize changes in the choroidal circulation. Treatment for dry ARMD involves a combination of zinc with anti-oxidant vitamins A, C, and E, which has been shown to reduce disease progression by around one third. For wet ARMD, anti-VEGF agents such as ranibizumab, bevacizumab, and pegaptanib are used to limit disease progression and stabilize or reverse visual loss. Laser photocoagulation may also be used to slow progression, but anti-VEGF therapies are usually preferred due to the risk of acute visual loss after treatment.

In summary, ARMD is a common cause of blindness in the UK that is strongly associated with advancing age, smoking, and family history. It can be classified into dry and wet forms, with wet ARMD carrying a worse prognosis. Diagnosis involves the use of various imaging techniques, and treatment options include a combination of zinc and anti-oxidant vitamins for dry ARMD and anti-VEGF agents or laser photocoagulation for wet ARMD.

Palliative care prescribing for pain is guided by NICE and SIGN guidelines. NICE recommends starting treatment with regular oral modified-release or immediate-release morphine, with immediate-release morphine for breakthrough pain. Laxatives should be prescribed for all patients initiating strong opioids, and antiemetics should be offered if nausea persists. Drowsiness is usually transient, but if it persists, the dose should be adjusted. SIGN advises that the breakthrough dose of morphine is one-sixth the daily dose, and all patients receiving opioids should be prescribed a laxative. Opioids should be used with caution in patients with chronic kidney disease, and oxycodone is preferred to morphine in patients with mild-moderate renal impairment. Metastatic bone pain may respond to strong opioids, bisphosphonates, or radiotherapy, and all patients should be considered for referral to a clinical oncologist for further treatment. When increasing the dose of opioids, the next dose should be increased by 30-50%. Conversion factors between opioids are also provided. Opioid side-effects are usually transient, such as nausea and drowsiness, but constipation can persist. In addition to strong opioids, bisphosphonates, and radiotherapy, denosumab may be used to treat metastatic bone pain.

Overall, the guidelines recommend starting with regular oral morphine and adjusting the dose as needed. Laxatives should be prescribed to prevent constipation, and antiemetics may be needed for nausea. Opioids should be used with caution in patients with chronic kidney disease, and oxycodone is preferred in patients with mild-moderate renal impairment. Metastatic bone pain may respond to strong opioids, bisphosphonates, or radiotherapy, and referral to a clinical oncologist should be considered. Conversion factors between opioids are provided, and the next dose should be increased by 30-50% when adjusting the dose. Opioid side-effects are usually transient, but constipation can persist. Denosumab may also be used to treat metastatic bone pain.

Understanding Legionnaires’ Disease: Causes, Symptoms, and Treatment

Legionnaires’ disease is a type of pneumonia that is caused by the Legionella bacteria. This disease is often overlooked as a possible cause of community-acquired pneumonia, but it is consistently ranked among the top three or four most common causes. The bacteria are found in water sources, and most patients contract the disease through aspiration.

One of the key symptoms of Legionnaires’ disease is hyponatremia, which is a low level of sodium in the blood. This symptom is more commonly associated with Legionnaires’ disease than with other types of pneumonia. The disease is also more likely to occur in patients who are immunocompromised, as cell-mediated immunity appears to be the primary host defense mechanism against Legionella infection.

The urinary antigen test is the preferred initial test for Legionnaires’ disease, but it has low sensitivity and is not particularly specific. The test detects only L. pneumophila serogroup 1, which causes most cases of the disease. Specific therapy includes antibiotics that can achieve high intracellular concentrations, such as macrolides, quinolones, or ketolides.

Predisposing factors for Legionnaires’ disease include age over 50, cigarette smoking, excessive alcohol intake, chronic lung disease, and immunosuppression. High fever and gastrointestinal symptoms are clinical clues to this disease. It is important for healthcare providers to consider Legionnaires’ disease as a possible cause of pneumonia, especially in patients with these risk factors.

When a woman expresses interest in starting hormone replacement therapy (HRT), it is important to gather a detailed medical history to determine her menopausal status. This includes information about her last menstrual period (LMP) and any bleeding patterns leading up to it. Based on this information, it appears that the woman in question is peri-menopausal, as she has not been without a period for a full year.

The primary reason for starting HRT is to alleviate vasomotor symptoms, such as hot flashes. However, it may also be used to prevent osteoporosis in women who have been diagnosed with premature menopause.

For women who still have a uterus, HRT should consist of a combination of estrogen and progesterone. The progesterone is essential for reducing the risk of endometrial cancer, which can occur when estrogen is used alone. Women who have had a hysterectomy will typically receive continuous estrogen-only therapy.

The type of HRT prescribed will depend on the woman’s menopausal status. Those who have had their LMP within the past year should receive cyclical combined HRT, while those who have been without a period for at least a year or who have experienced premature menopause should receive continuous combined HRT.

For women who are unable or unwilling to take HRT, there are several non-hormonal treatments available for vasomotor symptoms. These include certain selective serotonin and noradrenaline reuptake inhibitors, clonidine, and gabapentin. However, sertraline is not effective for treating hot flashes. It is worth noting that the National Institute for Health and Clinical Excellence (NICE) does not recommend the use of herbal or complementary therapies for managing hot flashes and night sweats.

Hormone replacement therapy (HRT) involves a small dose of oestrogen and progestogen to alleviate menopausal symptoms. The indications for HRT have changed due to the long-term risks, and it is primarily used for vasomotor symptoms and preventing osteoporosis in younger women. HRT consists of natural oestrogens and synthetic progestogens, and can be taken orally or transdermally. Transdermal is preferred for women at risk of venous thromboembolism.

The child is experiencing life-threatening acute asthma, which is a medical emergency. This is defined as having any of the following features: SpO2 below 92%, peak expiratory flow below 33% of the best or predicted, silent chest, cyanosis, poor respiratory effort, hypotension, exhaustion, or confusion. Therefore, 999 should be called immediately. This is not moderate or mild acute asthma, nor is it acute severe asthma, as the child is showing signs of cyanosis. Acute severe asthma is defined as having any of the following: SpO2 between 33-50% of the best or predicted, inability to complete sentences in one breath or too breathless to talk or feed, heart rate above 125 beats/min (for ages over 5) or above 140 beats/min (for ages 1-5), or respiratory rate above 30 breaths/min (for ages over 5) or above 40 breaths/min (for ages 1-5).

If a patient is suspected of having a TIA and visits their GP within 7 days, they should receive immediate treatment with 300 mg aspirin and be referred to a specialist for review within 24 hours. NICE guidelines also suggest considering gastric protection with a PPI if necessary.

A transient ischaemic attack (TIA) is a brief period of neurological deficit caused by a vascular issue, lasting less than an hour. The original definition of a TIA was based on time, but it is now recognized that even short periods of ischaemia can result in pathological changes to the brain. Therefore, a new ’tissue-based’ definition is now used. The clinical features of a TIA are similar to those of a stroke, but the symptoms resolve within an hour. Possible features include unilateral weakness or sensory loss, aphasia or dysarthria, ataxia, vertigo, or loss of balance, visual problems, and sudden transient loss of vision in one eye (amaurosis fugax).

NICE recommends immediate antithrombotic therapy with aspirin 300 mg unless the patient has a bleeding disorder or is taking an anticoagulant. If the patient has had more than one TIA or has a suspected cardioembolic source or severe carotid stenosis, specialist review is necessary. Urgent assessment is required within 24 hours for patients who have had a suspected TIA in the last 7 days. Referral for specialist assessment is necessary as soon as possible within 7 days for patients who have had a suspected TIA more than a week previously. Neuroimaging and carotid imaging are recommended, and antithrombotic therapy is necessary. Carotid artery endarterectomy should only be considered if the carotid stenosis is greater than 70% according to ECST criteria or greater than 50% according to NASCET criteria.

New-onset Achilles tendon disorders, including tendinitis and tendon rupture, are likely caused by ciprofloxacin, a medication with important side effects to consider.

Achilles tendon disorders are a common cause of pain in the back of the heel. These disorders can include tendinopathy, partial tears, and complete ruptures of the Achilles tendon. Certain factors, such as the use of quinolone antibiotics and high cholesterol levels, can increase the risk of developing these disorders. Symptoms of Achilles tendinopathy typically include gradual onset of pain that worsens with activity, as well as morning stiffness. Treatment for this condition usually involves pain relief, reducing activities that exacerbate the pain, and performing calf muscle eccentric exercises.

In contrast, an Achilles tendon rupture is a more serious condition that requires immediate medical attention. This type of injury is often caused by sudden, forceful movements during sports or running. Symptoms of an Achilles tendon rupture include an audible popping sound, sudden and severe pain in the calf or ankle, and an inability to walk or continue the activity. To help diagnose an Achilles tendon rupture, doctors may use Simmond’s triad, which involves examining the foot for abnormal angles and feeling for a gap in the tendon. Ultrasound is typically the first imaging test used to confirm a diagnosis of Achilles tendon rupture. If a rupture is suspected, it is important to seek medical attention from an orthopaedic specialist as soon as possible.

Treatment Options for Guillain-Barré Syndrome

Guillain–Barré syndrome (GBS) is an autoimmune disorder that affects the peripheral nerves, resulting in symmetrical weakness, hyporeflexia, and paraesthesia. The condition often occurs after an infection, usually involving the respiratory or gastrointestinal tract. The most commonly used treatment for GBS is intravenous immunoglobulin (IVIG), which helps to reduce the severity and duration of symptoms. Plasmapheresis (plasma exchange) is another option that filters antibodies from the patient’s plasma.

However, corticosteroids such as intravenous prednisolone have not been shown to improve GBS symptoms and may even prolong recovery. Haemodialysis is not necessary unless the patient has concurrent renal failure. Antivirals such as intravenous acyclovir have no role in managing GBS as it is not a viral illness. Although a bacterial infection may precede GBS, antibiotics such as intravenous ceftriaxone are not used to treat the autoimmune process causing the neurological symptoms. In some cases, patients with GBS may require invasive ventilation, which may cause pneumonia and require treatment with antibiotics.

The patient is experiencing dyspepsia but does not exhibit any alarming symptoms nor is taking any medication that could trigger the condition. Lifestyle modifications should be recommended, followed by either a month-long administration of a full dose proton pump inhibitor (PPI) or testing and treatment for Helicobacter pylori.

Management of Dyspepsia and Referral for Possible Cancer

Dyspepsia is a common symptom that can be caused by various factors, including medication and lifestyle choices. However, it can also be a sign of underlying conditions such as stomach or oesophageal cancer. The 2015 NICE guidelines provide updated advice on when urgent referral for endoscopy is necessary. Patients with dysphagia or an upper abdominal mass consistent with stomach cancer should be referred urgently. Patients aged 55 years or older with weight loss and upper abdominal pain, reflux, or dyspepsia should also be referred urgently. Non-urgent referrals include patients with haematemesis or those with treatment-resistant dyspepsia, upper abdominal pain with low haemoglobin levels, or raised platelet count with other symptoms.

For patients with undiagnosed dyspepsia, a step-wise approach is recommended. First, medications should be reviewed for possible causes. Lifestyle advice should also be given. If symptoms persist, a trial of full-dose proton pump inhibitor for one month or a ‘test and treat’ approach for H. pylori can be tried. If symptoms persist after either approach, the alternative should be attempted. Testing for H. pylori infection can be done using a carbon-13 urea breath test, stool antigen test, or laboratory-based serology. If symptoms resolve following test and treat, there is no need to check for H. pylori eradication. However, if repeat testing is required, a carbon-13 urea breath test should be used.

Trochanteric bursitis is no longer the preferred term and has been replaced by greater trochanteric pain syndrome. The x-ray reveals joint space narrowing, which is a common occurrence. Osteoarthritis is unlikely due to the palpable pain and short duration of symptoms.

Causes of Hip Pain in Adults

Hip pain in adults can be caused by a variety of conditions. Osteoarthritis is a common cause, with pain that worsens with exercise and improves with rest. Reduced internal rotation is often the first sign, and risk factors include age, obesity, and previous joint problems. Inflammatory arthritis can also cause hip pain, with pain typically worse in the morning and accompanied by systemic features and raised inflammatory markers. Referred lumbar spine pain may be caused by femoral nerve compression, which can be tested with a positive femoral nerve stretch test. Greater trochanteric pain syndrome, or trochanteric bursitis, is caused by repeated movement of the iliotibial band and is most common in women aged 50-70 years. Meralgia paraesthetica is caused by compression of the lateral cutaneous nerve of the thigh and typically presents as a burning sensation over the antero-lateral aspect of the thigh. Avascular necrosis may have gradual or sudden onset and may follow high dose steroid therapy or previous hip fracture or dislocation. Pubic symphysis dysfunction is common in pregnancy and presents with pain over the pubic symphysis with radiation to the groins and medial aspects of the thighs, often with a waddling gait. Transient idiopathic osteoporosis is an uncommon condition sometimes seen in the third trimester of pregnancy, with groin pain and limited range of movement in the hip, and patients may be unable to weight bear. ESR may be elevated in this condition.

Skin Conditions: Palmoplantar Pustulosis, Bullous Pemphigoid, Contact Dermatitis, Eczema, and Secondary Syphilis

Palmoplantar Pustulosis: A chronic inflammatory skin condition that affects the palms and soles, often associated with chronic plaque psoriasis and smoking. It presents with painful cracking, fissuring, and crops of sterile pustules that are severely itchy. Topical treatments and phototherapy can be used.

Bullous Pemphigoid: An autoimmune skin disease that forms large fluid-filled blisters, typically affecting people over 80 years old with underlying neurological or malignant conditions. The age and presenting features in this man are not typical for bullous pemphigoid.

Contact Dermatitis: A type of eczema triggered by contact with a particular substance, causing a red, dry, and scaly rash only in the areas that have been in contact with the irritant. Pustules are not a feature of this condition, and it would be unusual for an irritant to have been in contact with the palms and soles.

Eczema: A chronic, itchy, inflammatory skin condition that commonly begins in childhood and affects flexural areas such as behind the knees or in the antecubital fossae. The palms of hands and soles of feet are usually spared.

Secondary Syphilis: A rash that may appear as rough, red or reddish-brown papules or patches, typically occurring on the trunk but frequently affecting the palms and soles. The rash doesn’t itch and can appear more obvious with physical activity or heat. It resolves spontaneously within several weeks but can recur over the next two years.

Understanding Lichen Planus

Lichen planus is a skin condition that is believed to be caused by an immune response, although the exact cause is unknown. It is characterized by an itchy, papular rash that typically appears on the palms, soles, genitalia, and flexor surfaces of the arms. The rash often has a polygonal shape and a distinctive white-lines pattern on the surface, known as Wickham’s striae. In some cases, new skin lesions may appear at the site of trauma, a phenomenon known as the Koebner phenomenon.

Oral involvement is common in around 50% of patients, with a white-lace pattern often appearing on the buccal mucosa. Nail changes may also occur, including thinning of the nail plate and longitudinal ridging. Lichenoid drug eruptions can be caused by certain medications, such as gold, quinine, and thiazides.

The main treatment for lichen planus is potent topical steroids. For oral lichen planus, benzydamine mouthwash or spray is recommended. In more extensive cases, oral steroids or immunosuppression may be necessary.

To calculate alcohol units, multiply the volume in milliliters by the alcohol by volume (ABV) and divide by 1,000.

Alcohol consumption guidelines were revised in 2016 by the Chief Medical Officer, based on recommendations from an expert group report. The most significant change was a reduction in the recommended maximum number of units of alcohol for men from 21 to 14, aligning with the guidelines for women. The government now advises that both men and women should not exceed 14 units of alcohol per week, and if they do, it is best to spread it evenly over three or more days. Pregnant women are advised not to drink alcohol at all, as it can cause long-term harm to the baby. One unit of alcohol is equivalent to 10 mL of pure ethanol, and the strength of a drink is determined by its alcohol by volume (ABV). Examples of one unit of alcohol include a 25ml single measure of spirits with an ABV of 40%, a third of a pint of beer with an ABV of 5-6%, and half a 175ml standard glass of red wine with an ABV of 12%. To calculate the number of units in a drink, multiply the number of millilitres by the ABV and divide by 1,000.

Blepharitis is a condition characterized by inflammation of the margins of the eyelids, typically caused by the growth of eyelashes inwards. Symptoms include discomfort, redness, and dryness of the eyes, but no visual impairment. Urgent referral to ophthalmology is necessary if suspected. Treatment involves conservative measures such as regular eye care using warm compresses.

Understanding Scleritis: Causes, Symptoms, and Treatment

Scleritis is a condition that involves inflammation of the sclera, which is the white outer layer of the eye. This condition is typically non-infectious and can cause a red, painful eye. The most common risk factor associated with scleritis is rheumatoid arthritis, but it can also be linked to other conditions such as systemic lupus erythematosus, sarcoidosis, and granulomatosis with polyangiitis.

Symptoms of scleritis include a red eye, which is often accompanied by pain and discomfort. Patients may also experience watering and photophobia, as well as a gradual decrease in vision.

Treatment for scleritis typically involves the use of oral NSAIDs as a first-line treatment. In more severe cases, oral glucocorticoids may be used. For resistant cases, immunosuppressive drugs may be necessary, especially if there is an underlying associated disease. With proper treatment, most patients with scleritis can achieve relief from their symptoms and prevent further complications.

An oral glucose tolerance test result of 8.4 mmol/L after 2 hours with a 75g glucose load suggests impaired glucose tolerance instead of impaired fasting glucose.

Type 2 diabetes mellitus can be diagnosed through a plasma glucose or HbA1c sample. The diagnostic criteria vary depending on whether the patient is experiencing symptoms or not. If the patient is symptomatic, a fasting glucose level of 7.0 mmol/l or higher or a random glucose level of 11.1 mmol/l or higher (or after a 75g oral glucose tolerance test) indicates diabetes. If the patient is asymptomatic, the same criteria apply but must be demonstrated on two separate occasions.

In 2011, the World Health Organization released supplementary guidance on the use of HbA1c for diagnosing diabetes. A HbA1c level of 48 mmol/mol (6.5%) or higher is diagnostic of diabetes mellitus. However, a HbA1c value of less than 48 mmol/mol (6.5%) does not exclude diabetes and may not be as sensitive as fasting samples for detecting diabetes. For patients without symptoms, the test must be repeated to confirm the diagnosis. It is important to note that increased red cell turnover can cause misleading HbA1c results.

There are certain conditions where HbA1c cannot be used for diagnosis, such as haemoglobinopathies, haemolytic anaemia, untreated iron deficiency anaemia, suspected gestational diabetes, children, HIV, chronic kidney disease, and people taking medication that may cause hyperglycaemia (such as corticosteroids).

Impaired fasting glucose (IFG) is defined as a fasting glucose level of 6.1 mmol/l or higher but less than 7.0 mmol/l. Impaired glucose tolerance (IGT) is defined as a fasting plasma glucose level less than 7.0 mmol/l and an OGTT 2-hour value of 7.8 mmol/l or higher but less than 11.1 mmol/l. People with IFG should be offered an oral glucose tolerance test to rule out a diagnosis of diabetes. A result below 11.1 mmol/l but above 7.8 mmol/l indicates that the person does not have diabetes but does have IGT.

Proton pump inhibitors (PPIs) are a type of medication that reduces the production of gastric acid by irreversibly blocking the hydrogen/potassium adenosine triphosphatase enzyme system, also known as the gastric proton pump. This is achieved by inhibiting the H+/K+ ATPase proton pump, not the H+/Na+ or H+/Ca2+ ATP proton pumps. PPIs, such as lansoprazole and omeprazole, are more effective than H2 receptor antagonists like ranitidine and are commonly used to treat peptic ulcer disease, gastro-oesophageal reflux disease (GORD), and as part of the triple therapy regimen for the eradication of Helicobacter pylori. Antihistamines, on the other hand, act on histamine receptors such as the H1 and H2 receptors, which are found in smooth muscle, vascular endothelial cells, and the central nervous system.

The recommended adult dose of adrenaline for anaphylaxis is 500 mcg, which is equivalent to 0.5 ml of a 1 in 1,000 solution.

Anaphylaxis is a severe and potentially life-threatening allergic reaction that affects the entire body. It can be caused by various triggers, including food, drugs, and insect venom. The symptoms of anaphylaxis typically occur suddenly and progress rapidly, affecting the airway, breathing, and circulation. Common signs include swelling of the throat and tongue, hoarse voice, respiratory wheeze, dyspnea, hypotension, and tachycardia. In addition, around 80-90% of patients experience skin and mucosal changes, such as generalized pruritus, erythematous rash, or urticaria.

The management of anaphylaxis requires prompt and decisive action, as it is a medical emergency. The Resuscitation Council guidelines recommend intramuscular adrenaline as the most important drug for treating anaphylaxis. The recommended doses of adrenaline vary depending on the patient’s age, ranging from 100-150 micrograms for infants under 6 months to 500 micrograms for adults and children over 12 years. Adrenaline can be repeated every 5 minutes if necessary, and the best site for injection is the anterolateral aspect of the middle third of the thigh. In cases of refractory anaphylaxis, IV fluids and expert help should be sought.

Following stabilisation, patients may be given non-sedating oral antihistamines to manage persisting skin symptoms. It is important to refer all patients with a new diagnosis of anaphylaxis to a specialist allergy clinic and provide them with an adrenaline injector as an interim measure before the specialist assessment. Patients should also be prescribed two adrenaline auto-injectors and trained on how to use them. A risk-stratified approach to discharge should be taken, as biphasic reactions can occur in up to 20% of patients. The Resus Council UK recommends a fast-track discharge for patients who have had a good response to a single dose of adrenaline and complete resolution of symptoms, while those who require two doses of IM adrenaline or have a history of biphasic reaction should be observed for at least 12 hours following symptom resolution.

The National Institute for Clinical Excellence updated its guideline for hypertension management in 2011, placing emphasis on the use of ambulatory blood pressure monitoring (ABPM) to confirm hypertension in individuals with elevated clinic readings. ABPM involves taking two measurements per hour during waking hours and using the average of at least 14 measurements to confirm a diagnosis of hypertension. Secondary causes of hypertension should be investigated in patients under 40 without traditional risk factors, those with other symptoms of secondary causes, and those with resistant hypertension. Hyperaldosteronism is the most common cause of secondary hypertension, and a trial of spironolactone may be used for both therapeutic and diagnostic purposes. Drug treatment for essential hypertension involves ACE inhibitors for those under 55 and calcium channel blockers for those over 55 or of black African or Caribbean origin. Step 2 involves using both ACE inhibitors and calcium channel blockers, while step 3 adds a thiazide-like diuretic. Further diuretics, beta-blockers, or alpha blockers may be considered in step 4, with expert advice sought. For a more detailed explanation, refer to the provided link.

NICE released updated guidelines in 2019 for the management of hypertension, building on previous guidelines from 2011. These guidelines aimed to classify hypertension into stages and recommend the use of ambulatory blood pressure monitoring (ABPM) and home blood pressure monitoring (HBPM) to accurately diagnose hypertension. This is important because some patients experience white coat hypertension, where their blood pressure rises in a clinical setting, leading to potential overdiagnosis of hypertension. ABPM and HBPM allow for a more accurate assessment of a patient’s overall blood pressure and can prevent overdiagnosis.

NICE recommends measuring blood pressure in both arms when considering a diagnosis of hypertension and repeating measurements if there is a difference of more than 20 mmHg between arms. If the blood pressure is >= 140/90 mmHg, NICE suggests offering ABPM or HBPM to confirm the diagnosis. If the blood pressure is >= 180/120 mmHg, referral for specialist assessment is recommended if there are signs of retinal haemorrhage or papilloedema or life-threatening symptoms. If target organ damage is identified, antihypertensive drug treatment may be started immediately.

ABPM involves taking at least 2 measurements per hour during the person’s usual waking hours and using the average value of at least 14 measurements. If ABPM is not tolerated, HBPM should be offered. HBPM involves taking two consecutive measurements at least 1 minute apart, twice daily for at least 4 days, and using the average value of all remaining measurements.

Interpreting the results of ABPM/HBPM is important for determining treatment. If the average blood pressure is >= 135/85 mmHg (stage 1 hypertension), treatment may be considered for patients under 80 years of age with target organ damage, established cardiovascular disease, renal disease, diabetes, or a 10-year cardiovascular risk equivalent to 10% or greater. In 2019, NICE also recommended considering antihypertensive drug treatment for adults under 60 with stage 1 hypertension and an estimated 10-year risk below 10%. If the average blood pressure is >= 150/95 mmHg (stage 2 hypertension), drug treatment should be offered regardless of age.
