Cavernosal blood gas analysis is a crucial investigation for patients presenting with priapism. In this case, the patient has a partially erect, non-painful penis that has persisted for over 4 hours, indicating non-ischaemic priapism. This type of priapism is caused by large volume arterial inflow to the penis from trauma or congenital malformation. Confirming whether the priapism is ischaemic or non-ischaemic through cavernosal blood gas analysis is essential for appropriate management. Ischaemic priapism is a medical emergency that requires aspiration of blood from the cavernosa, while non-ischaemic priapism can be managed with observation initially. In paediatric patients, a doppler ultrasound may be a better alternative to cavernosal blood gases due to the potential trauma of the procedure.

A CT pelvis is not recommended in this case as it would expose the child to unnecessary radiation. Instead, a doppler ultrasound can be used to investigate the arterial/venous blood flow in the penis. A clotting screen may be useful if the patient has a history of bleeding problems or a family history of haemoglobinopathies. However, it should not delay cavernosal blood gas analysis as it is crucial to confirm the type of priapism. Testicular ultrasound is not a useful imaging modality for investigating priapism. If an imaging modality is required to assess penile blood flow, a doppler ultrasound is the preferred option.

Understanding Priapism: Causes, Symptoms, and Management

Priapism is a medical condition characterized by a persistent penile erection that lasts longer than four hours and is not associated with sexual stimulation. There are two types of priapism: ischaemic and non-ischaemic, each with a different pathophysiology. Ischaemic priapism is caused by impaired vasorelaxation, resulting in reduced vascular outflow and trapping of de-oxygenated blood within the corpus cavernosa. Non-ischaemic priapism, on the other hand, is due to high arterial inflow, often caused by fistula formation due to congenital or traumatic mechanisms.

Priapism can affect individuals of all ages, with a bimodal distribution of age at presentation, with peaks between 5-10 years and 20-50 years of age. The incidence of priapism has been estimated at up to 5.34 per 100,000 patient-years. There are various causes of priapism, including idiopathic, sickle cell disease or other haemoglobinopathies, erectile dysfunction medication, trauma, and drug use (both prescribed and recreational).

Patients with priapism typically present acutely with a persistent erection lasting over four hours and pain localized to the penis. A history of haemoglobinopathy or medication use may also be present. Cavernosal blood gas analysis and Doppler or duplex ultrasonography can be used to differentiate between ischaemic and non-ischaemic priapism and assess blood flow within the penis. Treatment for ischaemic priapism is a medical emergency and includes aspiration of blood from the cavernosa, injection of a saline flush, and intracavernosal injection of a vasoconstrictive agent. Non-ischaemic priapism, on the other hand, is not a medical emergency and is usually observed as a first-line option.

In the case of pulseless electrical activity, which is a non-shockable rhythm, the ALS algorithm requires the administration of adrenaline as soon as intravascular access is achieved. This should be done immediately after the rhythm check, following two more minutes of CPR. The recommended dose is 1mg IV, which should be repeated every 3-5 minutes. It is important to note that intramuscular adrenaline is not appropriate for cardiac arrest, and IV amiodarone is not indicated for non-shockable rhythms. While it is correct to avoid shocking the patient, it is incorrect to delay drug administration until the next rhythm check. The most recent Resuscitation Council Guidelines (2021) support the immediate administration of adrenaline in non-shockable rhythms.

The 2015 Resus Council guidelines for adult advanced life support outline the steps to be taken when dealing with patients with shockable and non-shockable rhythms. For both types of patients, chest compressions are a crucial part of the process, with a ratio of 30 compressions to 2 ventilations. Defibrillation is recommended for shockable rhythms, with a single shock for VF/pulseless VT followed by 2 minutes of CPR. Adrenaline and amiodarone are the drugs of choice for non-shockable rhythms, with adrenaline given as soon as possible and amiodarone administered after 3 shocks for VF/pulseless VT. Thrombolytic drugs should be considered if a pulmonary embolus is suspected. Atropine is no longer recommended for routine use in asystole or PEA. Oxygen should be titrated to achieve saturations of 94-98% following successful resuscitation. The Hs and Ts should be considered as potential reversible causes of cardiac arrest.

Understanding Optic Neuritis: Symptoms and Differential Diagnosis

Optic neuritis is a condition that can be either idiopathic or secondary to multiple sclerosis. Patients with optic neuritis typically experience periocular pain associated with eye movement, as well as a loss of color vision. Visual field defects, such as a central scotoma, can also occur. If the other eye is uninvolved, there is typically a relative afferent pupillary defect.

It is important to differentiate optic neuritis from other conditions that can cause similar symptoms. A stroke, for example, would not typically cause eye pain or affect color vision. Acute-angle-closure glaucoma can also be ruled out if intraocular pressure is within the normal range. Cerebral venous thrombosis would usually cause sudden painless loss of vision with severe retinal hemorrhages on fundoscopy. In cases of raised intracranial pressure, papilledema would be seen in both optic discs.

Overall, understanding the symptoms and differential diagnosis of optic neuritis is crucial for proper diagnosis and treatment.

This woman is experiencing sialadenitis, which is inflammation of the salivary gland. It is likely caused by a stone blocking the duct. The submandibular gland is located below the jawline and its duct drains into the floor of the mouth. When there is a discharge from this duct, it can cause a bad taste in the mouth. There are three main salivary glands: the parotid glands, which are located in front of and below each ear, the submandibular glands, which are located below the jawline, and the sublingual glands, which are located beneath the tongue. Disorders of these glands can be caused by infection, inflammation, obstruction, or malignancy. Swelling of the submandibular gland can be caused by a stone or a tumor, which can be either benign or malignant.

Salivary Glands and Their Pathologies

Salivary glands are responsible for producing saliva, which aids in digestion and protects the mouth from harmful bacteria. There are three pairs of salivary glands: parotid, submandibular, and sublingual. The parotid gland is the most common site for tumors, while the submandibular gland is most commonly affected by stones.

Tumors in the salivary glands are rare, but when they do occur, 80% of them are found in the parotid gland. Of these, 80% are pleomorphic adenomas, which are benign. These tumors typically grow slowly and are painless, but surgical removal carries a risk of damage to the facial nerve (CN VII). Warthin’s tumor is another benign tumor that affects the salivary glands, but it is less common than pleomorphic adenomas.

Stones in the salivary glands can cause recurrent pain and swelling, especially when eating. They are most commonly found in the submandibular gland and can lead to infection if left untreated. Other causes of salivary gland enlargement include viral or bacterial infections, as well as autoimmune disorders like Sjogren’s syndrome. Proper diagnosis and treatment are important for managing these conditions and preventing complications.

Understanding Holmes-Adie Pupil

Holmes-Adie pupil is a condition that is more commonly observed in women and is considered a benign condition. It is one of the possible causes of a dilated pupil. In about 80% of cases, it affects only one eye. The main characteristic of this condition is a dilated pupil that remains small for an unusually long time after it has constricted. The pupil also reacts slowly to accommodation but poorly or not at all to light.

Holmes-Adie syndrome is a condition that is associated with Holmes-Adie pupil. It is characterized by the absence of ankle and knee reflexes. This condition is not harmful and does not require any treatment.

Vasectomy: A Simple and Effective Male Sterilisation Method

Vasectomy is a male sterilisation method that has a failure rate of 1 per 2,000, making it more effective than female sterilisation. The procedure is simple and can be done under local anesthesia, with some cases requiring general anesthesia. After the procedure, patients can go home after a couple of hours. However, it is important to note that vasectomy does not work immediately.

To ensure the success of the procedure, semen analysis needs to be performed twice following a vasectomy before a man can have unprotected sex. This is usually done at 12 weeks after the procedure. While vasectomy is generally safe, there are some complications that may arise, such as bruising, hematoma, infection, sperm granuloma, and chronic testicular pain. This pain affects between 5-30% of men.

In the event that a man wishes to reverse the procedure, the success rate of vasectomy reversal is up to 55% if done within 10 years. However, the success rate drops to approximately 25% after more than 10 years. Overall, vasectomy is a simple and effective method of male sterilisation, but it is important to consider the potential complications and the need for semen analysis before engaging in unprotected sex.

Necrobiosis lipoidica diabeticorum is a condition characterized by waxy yellow shin lesions that often occur in individuals with diabetes.

Understanding Shin Lesions: Differential Diagnosis and Characteristic Features

Shin lesions can be caused by a variety of conditions, and it is important to differentiate between them in order to provide appropriate treatment. The four most common conditions that can cause shin lesions are erythema nodosum, pretibial myxoedema, pyoderma gangrenosum, and necrobiosis lipoidica diabeticorum.

Erythema nodosum is characterized by symmetrical, tender, erythematous nodules that heal without scarring. It is often caused by streptococcal infections, sarcoidosis, inflammatory bowel disease, or certain medications such as penicillins, sulphonamides, or oral contraceptive pills.

Pretibial myxoedema, on the other hand, is seen in Graves’ disease and is characterized by symmetrical, erythematous lesions that give the skin a shiny, orange peel appearance.

Pyoderma gangrenosum initially presents as a small red papule, which later develops into deep, red, necrotic ulcers with a violaceous border. It is idiopathic in 50% of cases, but may also be seen in inflammatory bowel disease, connective tissue disorders, and myeloproliferative disorders.

Finally, necrobiosis lipoidica diabeticorum is characterized by shiny, painless areas of yellow/red skin typically found on the shin of diabetics. It is often associated with telangiectasia.

In summary, understanding the differential diagnosis and characteristic features of shin lesions can help healthcare professionals provide appropriate treatment and improve patient outcomes.

It is possible that this individual has developed toxic megacolon, which is characterized by a transverse colon diameter exceeding 6 cm and accompanying symptoms of systemic distress. Treatment for toxic megacolon typically involves intensive medical intervention for a period of 24-72 hours. If there is no improvement in the patient’s condition during this time, a colectomy may be necessary.

Understanding Ulcerative Colitis Flares

Ulcerative colitis is a chronic inflammatory bowel disease that can cause flares or periods of worsening symptoms. While most flares occur without a clear trigger, there are several factors that are often associated with them. These include stress, certain medications such as NSAIDs and antibiotics, and even quitting smoking.

Flares of ulcerative colitis can be classified as mild, moderate, or severe based on the frequency and severity of symptoms. Mild flares may involve fewer than four stools a day with or without blood, while moderate flares may include four to six stools a day with minimal systemic disturbance. Severe flares, on the other hand, may involve more than six stools a day containing blood, as well as evidence of systemic disturbance such as fever, tachycardia, abdominal tenderness, distension, reduced bowel sounds, anemia, and hypoalbuminemia.

Patients with evidence of severe disease should be admitted to the hospital for close monitoring and treatment. Understanding the triggers and symptoms of ulcerative colitis flares can help patients manage their condition and seek appropriate medical care when necessary.

The recommended first-line treatment for patients with heart failure with reduced LVEF is a combination of a beta blocker and an ACE inhibitor. In this case, bisoprolol and ramipril are the appropriate medications to prescribe. The patient’s symptoms, medical history, and reduced left ventricular ejection fraction support this treatment plan. Amlodipine and ramipril, bisoprolol and amlodipine, and bisoprolol and furosemide are not recommended as initial treatments for heart failure with reduced LVEF.

Drug Management for Chronic Heart Failure: NICE Guidelines

Chronic heart failure is a serious condition that requires proper management to improve patient outcomes. In 2018, the National Institute for Health and Care Excellence (NICE) updated their guidelines on drug management for chronic heart failure. The guidelines recommend first-line therapy with both an ACE-inhibitor and a beta-blocker, with clinical judgement used to determine which one to start first. Second-line therapy involves the use of aldosterone antagonists, which should be monitored for hyperkalaemia. SGLT-2 inhibitors are also increasingly being used to manage heart failure with a reduced ejection fraction. Third-line therapy should be initiated by a specialist and may include ivabradine, sacubitril-valsartan, hydralazine in combination with nitrate, digoxin, or cardiac resynchronisation therapy. Other treatments such as annual influenza and one-off pneumococcal vaccines are also recommended.

Overall, the NICE guidelines provide a comprehensive approach to drug management for chronic heart failure. It is important to note that loop diuretics have not been shown to reduce mortality in the long-term, and that ACE-inhibitors and beta-blockers have no effect on mortality in heart failure with preserved ejection fraction. Healthcare professionals should carefully consider the patient’s individual needs and circumstances when determining the appropriate drug therapy for chronic heart failure.

Timolol, a beta blocker, is effective in treating primary open-angle glaucoma by reducing the production of aqueous fluid. This condition is characterized by increased intraocular pressure due to inefficient drainage of fluid in the eye’s trabecular meshwork. Symptoms include gradual loss of vision, particularly in the peripheral fields. Brimonidine, an alpha-adrenergic agonist, also reduces aqueous fluid production and increases uveoscleral outflow. However, drugs that decrease uveoscleral outflow or increase aqueous fluid production would worsen the patient’s condition. Glucocorticoids can cause reduced drainage of aqueous humour and are implicated in causing open-angle glaucoma. Latanoprost, a prostaglandin analogue, increases uveoscleral outflow.

Glaucoma is a condition where the optic nerve is damaged due to increased pressure in the eye. Primary open-angle glaucoma is a type where the iris is clear of the trabecular meshwork, which is responsible for draining aqueous humour from the eye. This results in increased resistance to outflow and raised intraocular pressure. The condition affects 0.5% of people over 40 years old and increases with age. Genetics also play a role, with first-degree relatives having a 16% chance of developing the disease. Symptoms are usually absent, and diagnosis is made through routine eye examinations. Investigations include visual field tests, tonometry, and slit lamp examinations. Treatment involves eye drops to lower intraocular pressure, with prostaglandin analogues being the first line of treatment. Surgery may be considered in refractory cases. Regular reassessment is necessary to monitor progression and prevent visual field loss.

Understanding Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo (BPPV) is a common condition that causes sudden dizziness and vertigo triggered by changes in head position. It typically affects individuals over the age of 55 and is less common in younger patients. Symptoms include vertigo triggered by movements such as rolling over in bed or looking upwards, and may be accompanied by nausea. Each episode usually lasts between 10-20 seconds and can be diagnosed through a positive Dix-Hallpike manoeuvre, which involves the patient experiencing vertigo and rotatory nystagmus.

Fortunately, BPPV has a good prognosis and often resolves on its own within a few weeks to months. Treatment options include the Epley manoeuvre, which is successful in around 80% of cases, and vestibular rehabilitation exercises such as the Brandt-Daroff exercises. While medication such as Betahistine may be prescribed, it tends to have limited value. However, it is important to note that around half of people with BPPV will experience a recurrence of symptoms 3-5 years after their initial diagnosis.

Overall, understanding BPPV and its symptoms can help individuals seek appropriate treatment and manage their condition effectively.

Most cases of sciatica can be resolved within 3 months through conservative treatment, and specialist referral is rarely necessary. However, if the pain persists after 4-6 weeks of physiotherapy and anti-neuropathic medication, referral to spinal surgery may be considered. Discharging the patient without proper intervention is not recommended as there is a risk of symptoms worsening and developing cauda equina syndrome. Patients should be advised to seek emergency care if they experience peri-anal or saddle sensory changes, difficulty urinating, or symptoms affecting both legs. Opiates are not recommended for neuropathic pain and may lead to dependence. Instead, a more appropriate and effective pain reliever for the patient’s age would be a non-steroidal anti-inflammatory drug (NSAID) like naproxen.

Understanding Prolapsed Disc and its Features

A prolapsed lumbar disc is a common cause of lower back pain that can lead to neurological deficits. It is characterized by clear dermatomal leg pain, which is usually worse than the back pain. The pain is often aggravated when sitting. The features of the prolapsed disc depend on the site of compression. For instance, L3 nerve root compression can cause sensory loss over the anterior thigh, weak quadriceps, reduced knee reflex, and a positive femoral stretch test. On the other hand, L4 nerve root compression can lead to sensory loss in the anterior aspect of the knee, weak quadriceps, reduced knee reflex, and a positive femoral stretch test.

The management of prolapsed disc is similar to that of other musculoskeletal lower back pain. It involves analgesia, physiotherapy, and exercises. According to NICE, the first-line treatment for back pain without sciatica symptoms is NSAIDs +/- proton pump inhibitors, rather than neuropathic analgesia. If the symptoms persist after 4-6 weeks, referral for consideration of MRI is appropriate. Understanding the features of prolapsed disc can help in the diagnosis and management of this condition.

It is recommended that premature babies receive their routine vaccinations based on their chronological age, without any adjustment for their gestational age. However, if a baby was born before 28 weeks of gestation, it is advisable to administer their initial immunizations while they are still in the hospital to minimize the risk of apnea.

Immunisation is the process of administering vaccines to protect individuals from infectious diseases. The Department of Health has provided guidance on the safe administration of vaccines in its publication ‘Immunisation against infectious disease’ in 2006. The guidance outlines general contraindications to immunisation, such as confirmed anaphylactic reactions to previous doses of a vaccine containing the same antigens or another component contained in the relevant vaccine. Vaccines should also be delayed in cases of febrile illness or intercurrent infection. Live vaccines should not be administered to pregnant women or individuals with immunosuppression.

Specific vaccines may have their own contraindications, such as deferring DTP vaccination in children with an evolving or unstable neurological condition. However, there are no contraindications to immunisation for individuals with asthma or eczema, a history of seizures (unless associated with fever), or a family history of autism. Additionally, previous natural infections with pertussis, measles, mumps, or rubella do not preclude immunisation. Other factors such as neurological conditions like Down’s or cerebral palsy, low birth weight or prematurity, and patients on replacement steroids (e.g. CAH) also do not contraindicate immunisation.

Emergency Management of Anaphylaxis: Medications and Interventions

Anaphylaxis is a severe and potentially life-threatening allergic reaction that requires immediate intervention. The following medications and interventions are commonly used in the emergency management of anaphylaxis:

Intramuscular (IM) adrenaline 0.5 mg (1 : 1000): This is the first-line treatment for anaphylaxis and should be administered immediately. It can be repeated every 5 minutes as needed, guided by vital signs, until the patient is stable.

Intravenous (IV) adrenaline 0.5 ml of 1 : 10 000: This is used in severe cases of anaphylaxis that do not respond to initial treatment. It should only be administered by experienced specialists and titrated carefully.

IV chlorphenamine in 0.9% saline (500 ml): Chlorphenamine is no longer recommended for initial emergency anaphylaxis management.

Reassurance and breathing exercises: These may be appropriate for a panic attack, but anaphylaxis requires immediate medical intervention.

Salbutamol: While bronchodilator therapy may be considered after initial resuscitation, the most important treatment for anaphylaxis is oxygen administration and IM adrenaline.

It is important to recognize the signs and symptoms of anaphylaxis and to act quickly to administer appropriate medications and interventions.

Management of Salmonella Infection in Children: Discharge Home with No Antibiotic Treatment

Salmonella infection is a common cause of gastroenteritis in children. The mainstay of treatment is oral rehydration for correction of dehydration and prevention of further fluid losses. Most children with salmonella infection do not need any specific treatment, and symptoms usually improve in a few days. Unless symptoms are severe, children with salmonella can usually be cared for at home. Infection with Salmonella spp. is a notifiable disease in the UK. Antibiotics should be considered in children with salmonella gastroenteritis who are aged < 6 months, malnourished or immunocompromised. However, in this case, the child is well hydrated and drinking as usual, and therefore, discharge home with no antibiotic treatment is the correct management approach.

The impairment of external rotation, both on active and passive movement, is a classic feature of adhesive capsulitis. This condition is the most likely diagnosis, as the patient’s symptoms of restricted active and passive external rotation have only been present for the last 4 weeks. Osteoarthritis, on the other hand, tends to present with a more chronic pain history. Adhesive capsulitis is often associated with endocrine conditions such as diabetes and thyroid disease, and has three distinct phases: painful, stiff, and recovery. Physiotherapy is the mainstay of treatment, but early intra-articular steroid injection may be considered if conservative measures are not effective. Biceps tendonitis typically presents with anterior shoulder pain and point tenderness over the biceps tendon on examination. Inflammatory arthritis is unlikely as there are no other joint involvements, morning stiffness, or systemic symptoms, and the history and examination are consistent with adhesive capsulitis. While osteoarthritis may be considered in the differential diagnosis, the duration of symptoms and classic examination findings suggest adhesive capsulitis as the most likely diagnosis.

Understanding Adhesive Capsulitis (Frozen Shoulder)

Adhesive capsulitis, commonly known as frozen shoulder, is a prevalent cause of shoulder pain that primarily affects middle-aged women. The exact cause of this condition is not yet fully understood. However, studies have shown that up to 20% of diabetics may experience an episode of frozen shoulder. Symptoms typically develop over several days, with external rotation being more affected than internal rotation or abduction. Both active and passive movement are affected, and patients usually experience a painful freezing phase, an adhesive phase, and a recovery phase. In some cases, the condition may affect both shoulders, which occurs in up to 20% of patients. The episode typically lasts between 6 months and 2 years.

Diagnosis of adhesive capsulitis is usually clinical, although imaging may be necessary for atypical or persistent symptoms. Unfortunately, no single intervention has been proven to improve the outcome in the long-term. However, there are several treatment options available, including nonsteroidal anti-inflammatory drugs (NSAIDs), physiotherapy, oral corticosteroids, and intra-articular corticosteroids.

Diagnostic Testing for Lichen Planus: Understanding Skin Patch Testing, Skin Prick Testing, and RAST

Lichen planus is a clinical diagnosis that can be made based on the characteristic appearance of the rash. However, in some cases, a biopsy may be helpful if the presentation is atypical. The diagnosis is typically made without the need for further testing, and treatment can be started promptly.

Skin patch testing and skin prick testing are not useful for diagnosing lichen planus, as they are mainly used for different types of hypersensitivity reactions. Skin patch testing is used for contact dermatitis and other type IV hypersensitivity reactions, while skin prick testing is used for type I hypersensitivity reactions, such as food allergies and pollen allergies.

Radioallergosorbent testing (RAST) is also unsuitable for diagnosing lichen planus, as it is used to determine the amount of immunoglobulin E (IgE) that reacts specifically with suspected or known allergens. RAST is useful for food allergies, inhaled allergens (such as pollen), and wasp/bee venom.

In summary, diagnostic testing is not typically required for lichen planus, as it can be diagnosed clinically. Skin patch testing, skin prick testing, and RAST are not useful for diagnosing lichen planus and are mainly used for different types of hypersensitivity reactions.

A possible cause of burning pain in the thigh is compression of the lateral cutaneous nerve, which can lead to a condition called meralgia paraesthetica. Meralgia paraesthetica, a condition characterized by burning pain in the thigh, may result from compression of the lateral cutaneous nerve of the thigh.

Understanding Meralgia Paraesthetica

Meralgia paraesthetica is a condition characterized by paraesthesia or anaesthesia in the distribution of the lateral femoral cutaneous nerve (LFCN). It is caused by entrapment of the LFCN, which can be due to various factors such as trauma, iatrogenic causes, or neuroma. Although not rare, it is often underdiagnosed.

The LFCN is a sensory nerve that originates from the L2/3 segments and runs beneath the iliac fascia before exiting through the lateral aspect of the inguinal ligament. Compression of the nerve can occur anywhere along its course, but it is most commonly affected as it curves around the anterior superior iliac spine. Meralgia paraesthetica is more common in men than women and is often seen in those aged between 30 and 40.

Patients with meralgia paraesthetica typically experience burning, tingling, coldness, or shooting pain, as well as numbness and deep muscle ache in the upper lateral aspect of the thigh. Symptoms are usually aggravated by standing and relieved by sitting. The condition can be mild and resolve spontaneously or severely restrict the patient for many years.

Diagnosis of meralgia paraesthetica can be made based on the pelvic compression test, which is highly sensitive. Injection of the nerve with local anaesthetic can also confirm the diagnosis and provide relief. Ultrasound is effective both for diagnosis and guiding injection therapy. Nerve conduction studies may also be useful. Overall, understanding meralgia paraesthetica is important for prompt diagnosis and management of this condition.

The presence of roughened red papules over the knuckles, known as Gottron’s papules, is indicative of dermatomyositis. This patient’s description of muscle weakness and associated skin changes suggests that she may have this condition. Bouchard’s and Heberden’s nodes, on the other hand, are associated with osteoarthritis and present as painless swellings of the proximal and distal interphalangeal joints, respectively. Macular lesions on the palms, such as Osler nodes and janeway lesions, are linked to endocarditis. Osler nodes are painful and caused by immune complex deposition, while janeway lesions are painless and caused by septic emboli.

Dermatomyositis is a condition that causes inflammation and muscle weakness, as well as distinct skin lesions. It can occur on its own or be associated with other connective tissue disorders or underlying cancers, particularly ovarian, breast, and lung cancer. Screening for cancer is often done after a diagnosis of dermatomyositis. Polymyositis is a variant of the disease that does not have prominent skin manifestations.

The skin features of dermatomyositis include a photosensitive macular rash on the back and shoulders, a heliotrope rash around the eyes, roughened red papules on the fingers’ extensor surfaces (known as Gottron’s papules), extremely dry and scaly hands with linear cracks on the fingers’ palmar and lateral aspects (known as mechanic’s hands), and nail fold capillary dilatation. Other symptoms may include proximal muscle weakness with tenderness, Raynaud’s phenomenon, respiratory muscle weakness, interstitial lung disease (such as fibrosing alveolitis or organizing pneumonia), dysphagia, and dysphonia.

Investigations for dermatomyositis typically involve testing for ANA antibodies, which are positive in around 80% of patients. Approximately 30% of patients have antibodies to aminoacyl-tRNA synthetases, including antibodies against histidine-tRNA ligase (also called Jo-1), antibodies to signal recognition particle (SRP), and anti-Mi-2 antibodies.

Sildenafil, a PDE 5 inhibitor, should not be taken with nitrates or nicorandil as it can enhance the vasodilating effects of these medications.

Understanding Phosphodiesterase Type V Inhibitors

Phosphodiesterase type V (PDE5) inhibitors are medications used to treat erectile dysfunction and pulmonary hypertension. These drugs work by increasing the levels of cGMP, which leads to the relaxation of smooth muscles in the blood vessels supplying the corpus cavernosum. The most well-known PDE5 inhibitor is sildenafil, also known as Viagra, which was the first drug of its kind. It is a short-acting medication that is usually taken one hour before sexual activity.

Other PDE5 inhibitors include tadalafil (Cialis) and vardenafil (Levitra). Tadalafil is longer-acting than sildenafil and can be taken on a regular basis, while vardenafil has a similar duration of action to sildenafil. However, these drugs are not suitable for everyone. Patients taking nitrates or related drugs, those with hypotension, and those who have had a recent stroke or myocardial infarction should not take PDE5 inhibitors.

Like all medications, PDE5 inhibitors can cause side effects. These may include visual disturbances, blue discolouration, non-arteritic anterior ischaemic neuropathy, nasal congestion, flushing, gastrointestinal side-effects, headache, and priapism. It is important to speak to a healthcare professional before taking any medication to ensure that it is safe and appropriate for you.

Overall, PDE5 inhibitors are an effective treatment for erectile dysfunction and pulmonary hypertension. However, they should only be used under the guidance of a healthcare professional and with careful consideration of the potential risks and benefits.

It is probable that this female patient has cerebral metastases and the recommended initial treatment is administering high-dose dexamethasone to alleviate cerebral edema. Additionally, anti-epileptic medication like phenytoin may be prescribed to decrease the occurrence of seizures.

Understanding Corticosteroids and Their Side-Effects

Corticosteroids are commonly prescribed therapies used to replace or augment the natural activity of endogenous steroids. They can be administered systemically or locally, depending on the condition being treated. However, the usage of corticosteroids is limited due to their numerous side-effects, which are more common with prolonged and systemic therapy.

Glucocorticoid side-effects include impaired glucose regulation, increased appetite and weight gain, hirsutism, hyperlipidaemia, Cushing’s syndrome, moon face, buffalo hump, striae, osteoporosis, proximal myopathy, avascular necrosis of the femoral head, immunosuppression, increased susceptibility to severe infection, reactivation of tuberculosis, insomnia, mania, depression, psychosis, peptic ulceration, acute pancreatitis, glaucoma, cataracts, suppression of growth in children, intracranial hypertension, and neutrophilia.

On the other hand, mineralocorticoid side-effects include fluid retention and hypertension. It is important to note that patients on long-term steroids should have their doses doubled during intercurrent illness. Longer-term systemic corticosteroids suppress the natural production of endogenous steroids, so they should not be withdrawn abruptly as this may precipitate an Addisonian crisis. The British National Formulary suggests gradual withdrawal of systemic corticosteroids if patients have received more than 40mg prednisolone daily for more than one week, received more than three weeks of treatment, or recently received repeated courses.

Elderly individuals taking antipsychotics are at a higher risk of experiencing stroke and VTE.

Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics. Typical antipsychotics work by blocking dopaminergic transmission in the mesolimbic pathways through dopamine D2 receptor antagonism. They are associated with extrapyramidal side-effects and hyperprolactinaemia, which are less common with atypical antipsychotics.

Extrapyramidal side-effects (EPSEs) are common with typical antipsychotics and include Parkinsonism, acute dystonia, sustained muscle contraction, akathisia, and tardive dyskinesia. The latter is a late onset of choreoathetoid movements that may be irreversible and occur in 40% of patients. The Medicines and Healthcare products Regulatory Agency has issued specific warnings when antipsychotics are used in elderly patients, including an increased risk of stroke and venous thromboembolism. Other side-effects include antimuscarinic effects, sedation, weight gain, raised prolactin, impaired glucose tolerance, neuroleptic malignant syndrome, reduced seizure threshold, and prolonged QT interval.

The patient’s symptoms suggest Brown-Séquard syndrome, which is caused by a hemisection of the spinal cord. This results in ipsilateral pyramidal weakness and loss of joint position/vibration sense, along with contralateral loss of pain/temperature sensation. The patient’s lesion is located in the left mid-thoracic cord. A lesion in the left lumbosacral plexus would only affect the left lower limb. A cervical cord lesion would affect the upper limbs. A central lesion would produce bilateral symmetrical defects, which is not the case here. A right mid-thoracic cord lesion would produce similar symptoms, but on the right side instead. Other spinal cord syndromes include complete cord transection, anterior cord syndrome, subacute combined degeneration of the cord, syringomyelia, and cauda equina syndrome. Each of these has a distinct set of symptoms and affected areas.

Hutchinson’s sign is a reliable indicator of potential ocular involvement.

Herpes Zoster Ophthalmicus: Symptoms, Treatment, and Complications

Herpes zoster ophthalmicus (HZO) is a condition that occurs when the varicella-zoster virus reactivates in the area supplied by the ophthalmic division of the trigeminal nerve. It is responsible for approximately 10% of shingles cases. The main symptom of HZO is a vesicular rash around the eye, which may or may not involve the eye itself. Hutchinson’s sign, a rash on the tip or side of the nose, is a strong indicator of nasociliary involvement and increases the risk of ocular involvement.

Treatment for HZO involves oral antiviral medication for 7-10 days, ideally started within 72 hours of symptom onset. Intravenous antivirals may be necessary for severe infections or immunocompromised patients. Topical antiviral treatment is not recommended for HZO, but topical corticosteroids may be used to treat any secondary inflammation of the eye. Ocular involvement requires urgent ophthalmology review to prevent complications such as conjunctivitis, keratitis, episcleritis, anterior uveitis, ptosis, and post-herpetic neuralgia.

In summary, HZO is a condition caused by the reactivation of the varicella-zoster virus in the ophthalmic division of the trigeminal nerve. It presents with a vesicular rash around the eye and may involve the eye itself. Treatment involves oral antiviral medication and urgent ophthalmology review is necessary for ocular involvement. Complications of HZO include various eye conditions, ptosis, and post-herpetic neuralgia.

Erythema nodosum caused by syphilis is uncommon.

Understanding Erythema Nodosum

Erythema nodosum is a condition characterized by inflammation of the subcutaneous fat, resulting in tender, erythematous, nodular lesions. These lesions typically occur over the shins but may also appear on other parts of the body such as the forearms and thighs. The condition usually resolves within six weeks, and the lesions heal without scarring.

There are several possible causes of erythema nodosum, including infections such as streptococci, tuberculosis, and brucellosis. Systemic diseases like sarcoidosis, inflammatory bowel disease, and Behcet’s can also lead to the condition. In some cases, erythema nodosum may be associated with malignancy or lymphoma. Certain drugs like penicillins, sulphonamides, and the combined oral contraceptive pill, as well as pregnancy, can also trigger the condition.

Overall, understanding the causes and symptoms of erythema nodosum is important for prompt diagnosis and treatment.

When a patient shows symptoms of acute stroke, it is crucial to immediately send them to the nearest stroke center. Treatment should not be administered until a diagnosis of ischemic stroke is confirmed. Once confirmed, the patient should be prescribed aspirin 300 mg daily for two weeks, followed by long-term use of clopidogrel 75 mg daily. Additionally, if the patient is not already taking a statin, it should be offered as a treatment option.

The Royal College of Physicians (RCP) and NICE have published guidelines on the diagnosis and management of patients following a stroke. The management of acute stroke includes maintaining normal levels of blood glucose, hydration, oxygen saturation, and temperature. Blood pressure should not be lowered in the acute phase unless there are complications. Aspirin should be given as soon as possible if a haemorrhagic stroke has been excluded. Anticoagulants should not be started until brain imaging has excluded haemorrhage. Thrombolysis with alteplase should only be given if administered within 4.5 hours of onset of stroke symptoms and haemorrhage has been definitively excluded. Mechanical thrombectomy is a new treatment option for patients with an acute ischaemic stroke. NICE recommends thrombectomy for people who have acute ischaemic stroke and confirmed occlusion of the proximal anterior circulation demonstrated by computed tomographic angiography or magnetic resonance angiography. Secondary prevention includes the use of clopidogrel and dipyridamole. Carotid artery endarterectomy should only be considered if carotid stenosis is greater than 70% according to ECST criteria or greater than 50% according to NASCET criteria.

Differential Diagnosis for Abdominal Symptoms: Irritable Bowel Syndrome, Ulcerative Colitis, Colorectal Cancer, Polycystic Ovarian Syndrome, and Ovarian Cancer

Abdominal symptoms can be caused by a variety of conditions, making differential diagnosis crucial. Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder characterized by abdominal pain, bloating, and altered bowel habits. It is more prevalent in women and can be associated with stress. Diagnosis is made by excluding other differential diagnoses, and management includes psychological support and dietary measures, with pharmacological treatment as adjunctive therapy.

Ulcerative colitis (UC) presents with rectal bleeding, frequent stools, and mucus discharge from the rectum. Physical examination may reveal proctitis and left-sided abdominal tenderness. UC is associated with extracolonic manifestations, but this patient’s symptoms are not consistent with a diagnosis of UC.

Colorectal cancer typically presents with rectal bleeding, change in bowel habits, abdominal pain, weight loss, and malaise. However, this patient’s age, clinical history, and normal examination findings make this diagnosis unlikely.

Polycystic ovarian syndrome (PCOS) presents with hyperandrogenism symptoms such as oligomenorrhea, hirsutism, and acne. Abdominal pain, bloating, and change in bowel habits are not features of PCOS.

Ovarian cancer may present with minimal or non-specific symptoms, but persistent abdominal distension and/or pain, early satiety, or lethargy may be present. However, this patient’s young age makes this diagnosis less likely.

The National Institute for Health and Care Excellence recommends that any woman aged over 50 years who presents with new IBS-like symptoms within the past year should have ovarian cancer excluded with a serum CA125 measurement.

Cholangitis can occur even in the absence of stones, although they are commonly associated with the condition. ERCP can be used to drain the biliary tree, but surgical exploration of the common bile duct may be necessary in certain cases.

Understanding Ascending Cholangitis

Ascending cholangitis is a bacterial infection that affects the biliary tree, with E. coli being the most common culprit. This condition is often associated with gallstones, which can predispose individuals to the infection. Patients with ascending cholangitis may present with Charcot’s triad, which includes fever, right upper quadrant pain, and jaundice. However, this triad is only present in 20-50% of cases. Other common symptoms include hypotension and confusion. In severe cases, Reynolds’ pentad may be observed, which includes the additional symptoms of hypotension and confusion.

To diagnose ascending cholangitis, ultrasound is typically used as a first-line investigation to look for bile duct dilation and stones. Raised inflammatory markers may also be observed. Treatment involves intravenous antibiotics and endoscopic retrograde cholangiopancreatography (ERCP) after 24-48 hours to relieve any obstruction.

Overall, ascending cholangitis is a serious condition that requires prompt diagnosis and treatment. Understanding the symptoms and risk factors associated with this condition can help individuals seek medical attention early and improve their chances of a successful recovery.

Identifying Bronchiectasis in a Patient with Cystic Fibrosis

Cystic Fibrosis (CF) is a genetic disorder that can lead to the development of bronchiectasis. Bronchiectasis is a condition characterized by dilated, thick-walled bronchi, which can result from continual or recurrent infection and inflammation caused by thick, difficult to expectorate mucus in patients with CF. In contrast, bronchiolitis is an acute lower respiratory infection that occurs in children aged <2 years, while asthma typically presents with variable wheeze, cough, breathlessness, and chest tightness. Chronic obstructive pulmonary disease (COPD) typically develops in smokers aged >40, and interstitial lung disease generally affects patients aged >45 and is associated with persistent breathlessness on exertion and cough. Therefore, in a patient with CF presenting with symptoms such as cough, breathlessness, and chest infections, bronchiectasis should be considered as a possible diagnosis.

Common Causes of Testicular Lumps: Varicocele, Epididymitis, Hydrocele, Inguinal Hernia, and Testicular Teratoma

Testicular lumps can be a cause for concern and require medical attention. Here are some common causes of testicular lumps:

Varicocele: This is a painless swelling of the testes on the left side, which can be described as a bag of worms within the spermatic cord above the testis. It tends to occur in those aged 12+ years and is rare in pre-pubertal boys. Varicoceles are associated with male infertility, and a quarter of men with abnormal semen parameters will have a varicocele.

Epididymitis: This is inflammation of the testis and epididymis caused by infection such as chlamydia infection, gonorrhoea, mumps, bacterial coliforms or syphilis. It may present as acute testicular pain, swelling and tenderness, and associated symptoms include urethritis, increased urinary frequency and dysuria. Systemic symptoms may include fever and rigors.

Hydrocele: This is a non-tender, painless, cystic scrotal swelling below and anterior to the testes. It will normally transilluminate and does not tend to reduce on lying flat. Although hydroceles can fluctuate in size and are affected by movement, they are not usually a cause for concern.

Inguinal hernia: This is a condition where a part of the intestine or other tissue protrudes through a weak spot in the abdominal muscles, causing a lump in the groin or scrotum. If reducible, the lump may disappear on lying flat.

Testicular teratoma: This is a solid testicular lump within the testis, which is suggestive of a tumour. Testicular cancers can be subdivided into seminomas, teratomas and yolk-sac tumours. Over 95% of testicular cancers arise from the germ cells. Teratomas typically present at age 20–30 years, whereas seminomas typically present at age 35–45 years.

Understanding Myxoedema Coma

Myxoedema coma is a serious medical condition that can lead to confusion and hypothermia. It is a medical emergency that requires immediate treatment. The treatment for myxoedema coma includes IV thyroid replacement, IV fluid, IV corticosteroids (until the possibility of coexisting adrenal insufficiency has been excluded), electrolyte imbalance correction, and sometimes rewarming.

In simpler terms, myxoedema coma is a condition that can cause confusion and low body temperature. It is a medical emergency that requires urgent treatment. The treatment involves giving medications through an IV, correcting any imbalances in the body’s fluids and electrolytes, and sometimes warming the body.

Differentiating Vascular Conditions: Causes and Symptoms

Cholesterol embolisation occurs when cholesterol crystals from a ruptured atherosclerotic plaque block small or medium arteries, often following an intervention like coronary angiography. This results in microvascular ischemia, which typically does not affect blood pressure or larger vessels, explaining the normal peripheral pulses in affected patients. Livedo reticularis, a purplish discoloration, may also occur due to microvascular ischemia.

Arterial thromboembolism is a common condition, especially in patients with established cardiovascular disease or risk factors like hypertension, hyperlipidemia, and smoking. It tends to affect larger vessels than cholesterol embolism, leading to the absence of peripheral pulses and gangrenous toes.

Buerger’s disease, also known as thromboangiitis obliterans, is a vasculitis that mainly affects young men who smoke. It presents with claudication of the arms or legs, with or without ulcers or gangrene. However, the acute onset of symptoms following an intervention makes cholesterol embolism a more likely diagnosis.

Deep vein thrombosis typically presents with a swollen, painful calf and does not display signs of arterial insufficiency like gangrene and livedo reticularis.

Takayasu’s arteritis is a rare form of large vessel vasculitis that mainly affects the aorta. It is more common in women and tends to present below the age of 30 years old with pulseless arms. However, this patient’s history is not typical for Takayasu’s arteritis.

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.

There is no association between erythema nodosum and telangiectasia in the surrounding area.

Skin Disorders Linked to Diabetes

Diabetes mellitus is a chronic metabolic disorder that affects various organs in the body, including the skin. Several skin disorders are associated with diabetes, including necrobiosis lipoidica, infections such as candidiasis and staphylococcal, neuropathic ulcers, vitiligo, lipoatrophy, and granuloma annulare. Necrobiosis lipoidica is characterized by shiny, painless areas of yellow, red, or brown skin, typically on the shin, and is often associated with surrounding telangiectasia. Infections such as candidiasis and staphylococcal can also occur in individuals with diabetes. Neuropathic ulcers are a common complication of diabetes, and vitiligo and lipoatrophy are also associated with the condition. Granuloma annulare is a papular lesion that is often slightly hyperpigmented and depressed centrally, but recent studies have not confirmed a significant association between diabetes mellitus and this skin disorder. It is important for individuals with diabetes to be aware of these potential skin complications and to seek medical attention if they notice any changes in their skin.

Tear-drop scaly papules suddenly appearing on the trunk and limbs may indicate guttate psoriasis.

Guttate psoriasis is a type of psoriasis that is more commonly seen in children and adolescents. It is often triggered by a streptococcal infection that occurred 2-4 weeks prior to the appearance of the lesions. The name guttate comes from the Latin word for drop, as the lesions appear as small, tear-shaped papules on the trunk and limbs. These papules are pink and scaly, and the onset of the condition is usually acute, occurring over a few days.

In most cases, guttate psoriasis will resolve on its own within 2-3 months. There is no clear evidence to support the use of antibiotics to treat the underlying streptococcal infection. Treatment options for guttate psoriasis include topical agents commonly used for psoriasis and UVB phototherapy. In cases where the condition recurs, a tonsillectomy may be necessary.

It is important to differentiate guttate psoriasis from pityriasis rosea, another skin condition that can present with similar symptoms. Guttate psoriasis is often preceded by a streptococcal sore throat, while pityriasis rosea may be preceded by a respiratory tract infection. The appearance of guttate psoriasis is characterized by tear-shaped papules on the trunk and limbs, while pityriasis rosea presents with a herald patch followed by multiple oval lesions with a fine scale. While guttate psoriasis resolves within a few months, pityriasis rosea typically resolves after around 6 weeks.

If you have been diagnosed with asymptomatic gallbladder stones, there is no need to worry. These stones are often found incidentally during imaging tests that are unrelated to gallstone disease. As long as you have not experienced any symptoms for at least a year before the diagnosis and the stones are located in a normal gallbladder and biliary tree, no intervention is necessary.

However, if you are experiencing symptoms or if the stones are located in the common bile duct, intervention is required. This can be done through surgical removal during laparoscopic cholecystectomy or through endoscopic retrograde cholangiopancreatography (ERCP) before or during the surgery. Rest assured that with proper intervention, you can effectively manage your gallbladder stones and prevent any complications.

Gallstones: Symptoms, Diagnosis, and Treatment

Gallstones are a common condition, with up to 24% of women and 12% of men affected. Local infection and cholecystitis may develop in up to 30% of cases, and 12% of patients undergoing surgery will have stones in the common bile duct. The majority of gallstones are of mixed composition, with pure cholesterol stones accounting for 20% of cases. Symptoms typically include colicky right upper quadrant pain that worsens after fatty meals. Diagnosis involves abdominal ultrasound and liver function tests, with magnetic resonance cholangiography or intraoperative imaging used to confirm the presence of stones in the bile duct. Treatment options include expectant management for asymptomatic gallstones, laparoscopic cholecystectomy for symptomatic gallstones, and early ERCP or surgical exploration for stones in the bile duct. Intraoperative cholangiography or laparoscopic ultrasound may be used to confirm anatomy or exclude CBD stones during surgery. ERCP carries risks such as bleeding, duodenal perforation, cholangitis, and pancreatitis.

Bacterial Skin Infections: Understanding the Causes and Symptoms

Erysipelas, a bacterial skin infection, is characterized by a tender, intensely erythematous, indurated plaque with a sharply demarcated border. It is caused by Streptococcus pyogenes, which is often sourced from the host’s nasopharynx. Prodromal symptoms such as malaise, chills, and high fever often precede the onset of skin lesions. Haemophilus influenzae can also cause cellulitis, but the skin lesion described in erysipelas is more consistent with this condition. Herpes simplex viruses cause a wide variety of disease states, including oropharyngeal infections and cold sores. Meningococcaemia, caused by Neisseria meningitidis, presents with a characteristic petechial skin rash on the trunk and legs. Understanding the causes and symptoms of these bacterial skin infections is crucial for proper diagnosis and treatment.

Understanding Personality Disorders: Emotionally Unstable Personality Disorder

Personality disorders are complex and severe disturbances in an individual’s character and behavior, often leading to personal and social disruption. These disorders are challenging to treat, but psychological and pharmacological interventions can help manage symptoms. One of the most common types of personality disorder is borderline personality disorder, characterized by intense emotions, unstable relationships, impulsive behavior, and anxieties about abandonment. Schizoid personality disorder, avoidant personality disorder, dependent personality disorder, and narcissistic personality disorder are other types of personality disorders, each with their own unique symptoms. However, the patient in this scenario is most consistent with borderline personality disorder. Understanding personality disorders is crucial in providing appropriate treatment and support for individuals struggling with these conditions.

In this scenario, the BNF suggests administering half of the oral dose of morphine when using the parenteral route (subcutaneous, intramuscular, or intravenous). If the patient is no longer able to swallow, a continuous subcutaneous infusion of morphine is typically given.

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.

Urgent Referral to Dermatology for Pemphigus Vulgaris Treatment

Pemphigus vulgaris requires urgent referral to the Dermatology Team for investigation and treatment. Supportive measures include wound care and antiseptic regimens to reduce the risk of secondary infection. Patients should also avoid activities that may traumatize the skin and mucous membranes during active phases. Topical steroids are used in milder cases, while systemic corticosteroids with topical treatments are preferred in advanced cases. Emollients and oral antihistamines are not first-line treatments. Topical clobetasone butyrate can be used in mild cases, but referral to Dermatology is still necessary. Topical clotrimazole is not a first-line treatment, and topical dapsone should not be started immediately without further investigation and treatment from Dermatology.
