The patient has symptoms of median nerve palsy, which can be caused by carpal tunnel syndrome, a known risk factor during pregnancy. Tinel’s sign and Phalen’s sign can reproduce the symptoms, and Froment’s sign is associated with ulnar nerve palsies.

Understanding Carpal Tunnel Syndrome

Carpal tunnel syndrome is a condition that occurs when the median nerve in the carpal tunnel is compressed. Patients with this condition typically experience pain or pins and needles in their thumb, index, and middle fingers. In some cases, the symptoms may even ascend proximally. Patients often shake their hand to obtain relief, especially at night.

During an examination, doctors may observe weakness of thumb abduction and wasting of the thenar eminence (not the hypothenar). Tapping on the affected area may cause paraesthesia, which is known as Tinel’s sign. Flexion of the wrist may also cause symptoms, which is known as Phalen’s sign.

Carpal tunnel syndrome can be caused by a variety of factors, including idiopathic reasons, pregnancy, oedema (such as heart failure), lunate fracture, and rheumatoid arthritis. Electrophysiology tests may show prolongation of the action potential in both motor and sensory nerves.

Treatment for carpal tunnel syndrome may include a 6-week trial of conservative treatments, such as corticosteroid injections and wrist splints at night. If symptoms persist or are severe, surgical decompression (flexor retinaculum division) may be necessary.

Causes of Gout: Medications and Other Factors

Gout is a type of joint inflammation that occurs due to the accumulation of monosodium urate monohydrate crystals in the synovium. This condition is caused by chronic hyperuricemia, which is characterized by high levels of uric acid in the blood (above 0.45 mmol/l).

Several medications and other factors can contribute to the development of gout. Diuretics such as thiazides and furosemide, as well as immunosuppressant drugs like ciclosporin, can increase the risk of gout. Alcohol consumption, cytotoxic agents, and pyrazinamide are also known to be associated with gout.

In addition, low-dose aspirin has been found to increase the risk of gout attacks, according to a systematic review. However, this risk needs to be weighed against the cardiovascular benefits of aspirin. Patients who are prescribed allopurinol, a medication used to treat gout, are not at an increased risk of gout attacks when taking low-dose aspirin.

Overall, it is important to be aware of the potential causes of gout, including medications and lifestyle factors, in order to prevent and manage this condition effectively.

A prolapsed disc is suspected based on the patient’s symptoms. However, even if an MRI scan confirms this diagnosis, the initial management would remain the same as most patients respond well to conservative treatment like physiotherapy.

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.

Supplementation of vitamin D and calcium along with oral bisphosphonate.

Managing the Risk of Osteoporosis in Patients Taking Corticosteroids

Osteoporosis is a significant risk for patients taking corticosteroids, which are commonly used in clinical practice. To manage this risk appropriately, the 2002 Royal College of Physicians (RCP) guidelines provide a concise guide to prevention and treatment. According to these guidelines, the risk of osteoporosis increases significantly when a patient takes the equivalent of prednisolone 7.5mg a day for three or more months. Therefore, it is important to manage patients in an anticipatory manner, starting bone protection immediately if it is likely that the patient will need to take steroids for at least three months.

The RCP guidelines divide patients into two groups based on age and fragility fracture history. Patients over the age of 65 years or those who have previously had a fragility fracture should be offered bone protection. For patients under the age of 65 years, a bone density scan should be offered, with further management dependent on the T score. If the T score is greater than 0, patients can be reassured. If the T score is between 0 and -1.5, a repeat bone density scan should be done in 1-3 years. If the T score is less than -1.5, bone protection should be offered.

The first-line treatment for corticosteroid-induced osteoporosis is alendronate. Patients should also be replete in calcium and vitamin D. By following these guidelines, healthcare professionals can effectively manage the risk of osteoporosis in patients taking corticosteroids.

Subacromial impingement is often characterized by a painful arc of abduction. This is likely the cause of the patient’s shoulder pain, which is accompanied by tenderness at the acromion and pain around the midpoint of abduction (typically between 60 to 120 degrees). These symptoms are not indicative of inflammatory arthritis affecting the acromioclavicular joint, which is rare. Osteoarthritis affecting the ACJ may cause tenderness and swelling, but not acromial tenderness or a painful arc in abduction. Cervical radiculopathy would cause neuropathic pain in the distribution of a cervical root, which is not consistent with the patient’s symptoms. Rheumatoid arthritis and other inflammatory arthropathies typically cause acute joint inflammation and effusion, which is not present in this case. A supraspinatus tear is a possible differential diagnosis, but the pain would be limited to the initial 60 degrees of abduction rather than the midpoint, indicating impingement as the more likely cause. Depending on the extent of the tear, abduction may also be limited due to difficulty initiating the movement.

Understanding Rotator Cuff Injuries

Rotator cuff injuries are a common cause of shoulder problems that can be classified into four types of disease: subacromial impingement, calcific tendonitis, rotator cuff tears, and rotator cuff arthropathy. The symptoms of a rotator cuff injury include shoulder pain that worsens during abduction.

The signs of a rotator cuff injury include a painful arc of abduction, which typically occurs between 60 and 120 degrees in cases of subacromial impingement. In cases of rotator cuff tears, the pain may be felt in the first 60 degrees of abduction. Additionally, tenderness over the anterior acromion may be present.

Temporal arteritis should be considered in an older patient experiencing a sudden onset of unilateral headache accompanied by jaw claudication and elevated ESR. Trigeminal neuralgia typically does not cause jaw stiffness, while acute angle-closure glaucoma presents with a red eye and does not involve jaw claudication. Although TMJ dysfunction can cause pain during chewing and extend to the scalp and headache, there is no additional information to suggest this as the cause. Therefore, temporal arteritis is the more probable diagnosis.

Understanding Temporal Arteritis

Temporal arteritis is a type of large vessel vasculitis that often overlaps with polymyalgia rheumatica (PMR). It is characterized by changes in the affected artery that skip certain sections while damaging others. This condition typically affects individuals who are over 60 years old and has a rapid onset, usually occurring in less than a month. The most common symptoms include headache and jaw claudication, while vision testing is a crucial investigation for all patients.

Temporal arteritis can lead to various ocular complications, with anterior ischemic optic neuropathy being the most common. This results from the occlusion of the posterior ciliary artery, leading to ischemia of the optic nerve head. Patients may experience temporary visual loss or even permanent visual loss, which is the most feared complication of this condition. Other symptoms may include diplopia, tender and palpable temporal artery, and features of PMR such as aching, morning stiffness in proximal limb muscles, lethargy, depression, low-grade fever, anorexia, and night sweats.

To diagnose temporal arteritis, doctors may look for raised inflammatory markers such as an ESR of over 50 mm/hr or elevated CRP levels. A temporal artery biopsy may also be performed to check for skip lesions. Urgent high-dose glucocorticoids should be given as soon as the diagnosis is suspected, and an ophthalmologist should review patients with visual symptoms on the same day. Treatment may also involve bone protection with bisphosphonates and low-dose aspirin, although the evidence supporting the latter is weak.

In summary, temporal arteritis is a serious condition that requires prompt diagnosis and treatment to prevent irreversible visual damage. Patients who experience symptoms such as headache, jaw claudication, and visual disturbances should seek medical attention immediately.

To effectively treat gout, it is important to understand the proper use of allopurinol. Starting prophylactic treatment with allopurinol should be delayed until 1-2 weeks after the inflammation has settled to avoid exacerbating and prolonging the attack. It may take several weeks to reduce uric acid levels to normal, and the dose should be titrated every few weeks until sUA levels are below 300 mmol/l. It is not recommended to start allopurinol during an acute attack, as it is unlikely to lead to complete remission of symptoms. Allopurinol use is not associated with an increased risk of acute pyelonephritis, but renal impairment may occur if the starting dose is too high. In mild cases, self-care may be considered, but if drug treatment is necessary, NSAIDs or colchicine can be prescribed. It is important to measure the baseline sUA level and consider prophylaxis in high-risk patients. When starting allopurinol, a low dose of NSAID or colchicine should be co-prescribed for at least 1 month to prevent acute attacks of gout.

In patients aged 75 years or older who have experienced a fragility fracture, alendronate should be initiated without delay, even in the absence of a DEXA scan. This patient meets the NICE criteria for bisphosphonate treatment, and while a calcium-rich diet and supplementation may be helpful, they are not sufficient for managing osteoporosis. Zoledronic acid may be considered if the patient cannot tolerate bisphosphonates, but it should not be the first-line treatment.

Managing Osteoporosis in Patients with Fragility Fracture

The management of patients with fragility fractures depends on their age. For patients aged 75 years and above, they are presumed to have underlying osteoporosis and should be started on first-line therapy, which is an oral bisphosphonate, without the need for a DEXA scan. However, the 2014 NOGG guidelines suggest that treatment should be started in all women over the age of 50 years who’ve had a fragility fracture, although BMD measurement may sometimes be appropriate, particularly in younger postmenopausal women.

On the other hand, for patients below 75 years old, a DEXA scan should be arranged to determine their ongoing fracture risk. The results of the scan can be entered into a FRAX assessment, along with the fact that they’ve had a fracture, to determine the appropriate management plan. For instance, if a 79-year-old woman sustains a Colles’ fracture, she is presumed to have osteoporosis and should be started on oral alendronate 70mg once weekly without a DEXA scan.

In summary, managing osteoporosis in patients with fragility fractures requires age consideration and appropriate assessment to determine the best management plan.

Treatment and Management of Paracetamol Overdose

Paracetamol overdose is a serious medical emergency that requires prompt treatment and management. Here are some important steps to take:

Give intravenous acetylcysteine immediately for patients who have taken a staggered overdose, which is defined as ingesting a potentially toxic dose of paracetamol over a period of over one hour. Patients who have taken a dose of paracetamol > 150 mg/kg are at risk of serious toxicity.

Observe the patient for 24 hours after treatment.

Measure serum paracetamol level and give acetylcysteine if the level is above the treatment line. Patients who have ingested > 75 mg/kg of paracetamol over a period of less than one hour should have their serum paracetamol levels measured four hours after ingestion. If this level is above the treatment line, they should be treated with intravenous acetylcysteine. If blood tests reveal an alanine aminotransferase above the upper limit of normal, patients should be started on acetylcysteine regardless of serum paracetamol levels.

Start haemodialysis if patients have an exceedingly high serum paracetamol concentration (> 700 mg/l) associated with an elevated blood lactate and coma.

Take bloods including a coagulation screen and start acetylcysteine if clotting is deranged. In patients where a serum paracetamol level is indicated (patients who have ingested > 75 mg/kg of paracetamol over a period of less than one hour), deranged liver function tests are an indication to start acetylcysteine regardless of serum paracetamol levels.

In summary, prompt treatment with intravenous acetylcysteine is crucial for patients who have taken a staggered overdose of paracetamol. Monitoring of serum paracetamol levels, liver function tests, and clotting factors can help guide further management. Haemodialysis may be necessary in severe cases.

Differential Diagnosis and Treatment of a Swollen, Hot, and Painful Joint in a Febrile Patient

When a patient presents with an acutely swollen, hot, and painful joint accompanied by fever, it is crucial to consider the possibility of septic arthritis or osteomyelitis. Both conditions require urgent medical attention, including prolonged courses of intravenous antibiotics and potential surgical intervention. Aspiration of the joint fluid for Gram staining and culture is necessary before starting empirical antibiotics. However, antibiotic treatment should not be delayed while awaiting results.

Intra-articular steroid injections are not appropriate for this patient, as they may worsen the condition significantly. Similarly, an IM injection of methylprednisolone could potentially have a significant effect on the immune system, leading to overwhelming sepsis. Oral colchicine is used to treat acute gout, which does not typically present with fever. In contrast, RA is a risk factor for developing septic arthritis, and immunosuppressive medications used to treat RA can also increase the risk.

Although oral flucloxacillin is indicated for the treatment of cellulitis, the history and examination findings in this case are more suggestive of septic arthritis. Intravenous antibiotics with or without surgical intervention are necessary for the treatment of septic arthritis. Therefore, it is crucial to differentiate between these conditions and provide appropriate treatment promptly.

Ottawa Rules for Ankle Injuries

The Ottawa Rules provide a guideline for determining whether an ankle x-ray is necessary after an injury. These rules have a sensitivity approaching 100%, meaning they are highly accurate. An ankle x-ray is only required if there is pain in the malleolar zone and one of the following findings: bony tenderness at the lateral malleolar zone or medial malleolar zone, or inability to walk four weight-bearing steps immediately after the injury and in the emergency department.

The lateral malleolar zone is from the tip of the lateral malleolus to include the lower 6 cm of the posterior border of the fibular, while the medial malleolar zone is from the tip of the medial malleolus to the lower 6 cm of the posterior border of the tibia. These rules help healthcare professionals determine whether an ankle x-ray is necessary, which can save time and resources. It is important to note that there are also Ottawa rules available for foot and knee injuries. By following these guidelines, healthcare professionals can provide efficient and effective care for ankle injuries.

Reactive arthritis is a type of joint inflammation that occurs after an infection, often caused by dysentery or a sexually transmitted infection. It is more common in men who have the HLA-B27 gene. Reactive arthritis is part of a group of diseases called spondyloarthropathies, which also includes ankylosing spondylitis, psoriatic arthritis, enteropathic arthritis, and undifferentiated arthritis. Unlike rheumatoid arthritis, reactive arthritis is not associated with rheumatoid factor. Symptoms of reactive arthritis include sudden, asymmetrical lower limb joint pain, which can occur a few days to weeks after the initial infection. Enthesitis, or inflammation where tendons and ligaments attach to bones, is also common and can cause plantar fasciitis or Achilles tendonitis. In some cases, reactive arthritis can also cause back pain and inflammation of the sacroiliac joint, as well as a sterile conjunctivitis. Treatment involves addressing the initial infection and may include medications such as sulfasalazine or methotrexate for relapsing cases. It is important to trace and treat sexual partners if necessary. Gout, rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis are other types of joint inflammation that have different symptoms and causes.

Gonococcal arthritis is characterized by migratory polyarthralgia, fever, tenosynovitis, and dermatitis, with a rash being a common feature. It is responsive to treatment and less destructive. Reactive arthritis is a triad of urethritis, seronegative arthritis, and conjunctivitis, often caused by infections of the digestive or reproductive systems. Tuberculous arthritis is caused by Mycobacterium tuberculosis and presents with pain, swelling, and stiffness of the affected joint, along with fatigue, malaise, and weight loss. Fungal arthritis is rare and causes a hot, swollen, red, and painful joint. Gout typically affects the first metatarsophalangeal joint and presents with hot, swollen, tender, and red joints, with normal uric acid levels not ruling out the diagnosis. Diagnosis is largely clinical, but synovial fluid examination can differentiate from pseudogout.

Patients starting bisphosphonates should be warned about potential oesophageal problems, particularly with alendronate. Any new symptoms following the introduction of this drug should be reviewed by a medical professional.

Bisphosphonates: Uses and Adverse Effects

Bisphosphonates are drugs that mimic the action of pyrophosphate, a molecule that helps prevent bone demineralization. They work by inhibiting osteoclasts, which are cells that break down bone tissue. This reduces the risk of bone fractures and can be used to treat conditions such as osteoporosis, hypercalcemia, Paget’s disease, and pain from bone metastases.

However, bisphosphonates can have adverse effects, including oesophageal reactions such as oesophagitis and ulcers, osteonecrosis of the jaw, and an increased risk of atypical stress fractures of the proximal femoral shaft in patients taking alendronate. Patients may also experience an acute phase response, which can cause fever, myalgia, and arthralgia. Hypocalcemia, or low calcium levels, can also occur due to reduced calcium efflux from bone, but this is usually not clinically significant.

To minimize the risk of adverse effects, patients taking oral bisphosphonates should swallow the tablets whole with plenty of water while sitting or standing. They should take the medication on an empty stomach at least 30 minutes before breakfast or other oral medications and remain upright for at least 30 minutes after taking the tablet. Hypocalcemia and vitamin D deficiency should be corrected before starting bisphosphonate treatment, and calcium supplements should only be prescribed if dietary intake is inadequate. The duration of bisphosphonate treatment varies depending on the patient’s level of risk, and some authorities recommend stopping treatment after five years for low-risk patients with a femoral neck T-score of > -2.5.

Understanding Kawasaki Disease: Diagnosis and Blood Test Results

Kawasaki disease is a clinical diagnosis that presents with a persistent fever and at least four of the following five criteria: bilateral conjunctival injection, polymorphous rash, oral changes, oedema and erythema in hands/feet, and cervical lymphadenopathy. Thrombocytosis is a common non-specific change seen in Kawasaki disease, and blood tests such as full blood count, urea and electrolytes, liver function, lipid profile, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) can support the diagnosis, assess severity, and monitor disease and treatment. Neutropenia is not usually associated with Kawasaki disease, and a raised white cell count with a relative neutrophilia is commonly seen. An elevated CRP with a normal ESR or an elevated ESR with a normal CRP would not be expected in Kawasaki disease, as both markers reflect acute inflammation. Kawasaki disease is associated with normocytic anaemia, but not macrocytic anaemia. It is important to arrange an echocardiogram as soon as possible to look for any initial evidence of coronary artery aneurysm, a common complication of Kawasaki disease.

Aortic dissection may be more likely to occur in individuals with Marfan’s syndrome due to the dilation of the aortic sinuses.

Understanding Marfan’s Syndrome

Marfan’s syndrome is a genetic disorder that affects the connective tissue in the body. It is caused by a defect in the FBN1 gene on chromosome 15, which codes for the protein fibrillin-1. This disorder is inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the defective gene from one parent to develop the condition. Marfan’s syndrome affects approximately 1 in 3,000 people.

The features of Marfan’s syndrome include a tall stature with an arm span to height ratio greater than 1.05, a high-arched palate, arachnodactyly (long, slender fingers), pectus excavatum (sunken chest), pes planus (flat feet), and scoliosis (curvature of the spine). In addition, individuals with Marfan’s syndrome may experience cardiovascular problems such as dilation of the aortic sinuses, mitral valve prolapse, and aortic aneurysm. They may also have lung issues such as repeated pneumothoraces. Eye problems are also common, including upwards lens dislocation, blue sclera, and myopia. Finally, dural ectasia, or ballooning of the dural sac at the lumbosacral level, may also occur.

In the past, the life expectancy of individuals with Marfan’s syndrome was around 40-50 years. However, with regular echocardiography monitoring and the use of beta-blockers and ACE inhibitors, this has improved significantly in recent years. Despite these improvements, aortic dissection and other cardiovascular problems remain the leading cause of death in individuals with Marfan’s syndrome.

Common Causes of Hip Problems in Children

Hip problems in children can be caused by a variety of conditions. Developmental dysplasia of the hip is often detected during newborn examinations and can be identified through positive Barlow’s and Ortolani’s tests, as well as unequal skin folds or leg length. Transient synovitis, also known as irritable hip, is the most common cause of hip pain in children aged 2-10 years and is associated with acute hip pain and viral infections.

Perthes disease is a degenerative condition that affects the hip joints of children between the ages of 4-8 years. It is more common in boys and can cause hip pain, stiffness, and reduced range of motion. Slipped upper femoral epiphysis is another condition that typically affects children aged 10-15 years, particularly those who are obese or male. It can cause knee or thigh pain and loss of internal rotation of the leg in flexion.

Juvenile idiopathic arthritis (JIA) is a type of arthritis that occurs in children under 16 years old and lasts for more than three months. Pauciarticular JIA, which affects four or fewer joints, is the most common type and can cause joint pain and swelling, as well as a limp. Finally, septic arthritis is an acute condition that causes hip pain and systemic upset, such as fever and severe limitation of the affected joint.

Overall, hip problems in children can have a variety of causes and should be evaluated by a healthcare professional to determine the appropriate treatment.

Compartment syndrome is the likely diagnosis in this case, as excessive use of breakthrough analgesia and a history of trauma followed by lower limb pain should raise suspicion. Compartment syndrome occurs when pressure builds up in a compartment due to oedema and blood, resulting in venous compression and compromised transferring nerves. In this case, the patient’s medial plantar nerve has been compromised, leading to reduced sensation in the medial aspect of the plantar foot and paresthesia. The fact that the patient is using the maximum dose of PRN morphine should raise clinical suspicion of compartment syndrome, as it can be extremely painful. Pallor is a late sign, and x-rays may not show any findings in the context of compartment syndrome.

Acute limb ischaemia is an unlikely diagnosis, as the usual presenting complaint is pain with associated pallor from reduced arterial perfusion, which is not present in this case. Common peroneal nerve injury is also unlikely, as this nerve supplies the dorsum and lateral aspects of the foot, whereas the medial plantar nerve has been compromised in this case. Posttraumatic osteomyelitis is also an unlikely diagnosis, as it typically presents more than 48 hours after the trauma, and the loss of sensation in the medial aspect of the plantar foot cannot be explained by this condition.

Compartment syndrome is a complication that can occur after fractures or vascular injuries. It is characterized by increased pressure within a closed anatomical space, which can lead to tissue death. Supracondylar fractures and tibial shaft injuries are the most common fractures associated with compartment syndrome. Symptoms include pain, numbness, paleness, and possible paralysis of the affected muscle group. Diagnosis is made by measuring intracompartmental pressure, with pressures over 20 mmHg being abnormal and over 40mmHg being diagnostic. X-rays typically do not show any pathology. Treatment involves prompt and extensive fasciotomies, with careful attention to decompressing deep muscles in the lower limb. Patients may develop myoglobinuria and require aggressive IV fluids. In severe cases, debridement and amputation may be necessary, as muscle death can occur within 4-6 hours.

The situation is complex as the patient requires bone protection due to her low T score and previous hip fracture. However, bisphosphonates are not suitable for her as they are contraindicated in patients with an eGFR below 35 mL/minute/1.73m(2), which she has due to her stage IV chronic kidney disease. Therefore, reintroducing alendronate or using IV zoledronate infusion is not an option. Repeating her DEXA scan at this point would not provide any additional information. While calcium and vitamin D supplementation should continue, they are not sufficient for her bone protection needs. The best option is denosumab, which would require administration in a secondary care setting and close monitoring of her calcium levels due to her renal disease.

The NICE guidelines for managing osteoporosis in postmenopausal women include offering vitamin D and calcium supplementation, with alendronate being the first-line treatment. If a patient cannot tolerate alendronate, risedronate or etidronate may be given as second-line drugs, with strontium ranelate or raloxifene as options if those cannot be taken. Treatment criteria for patients not taking alendronate are based on age, T-score, and risk factors. Bisphosphonates have been shown to reduce the risk of fractures, with alendronate and risedronate being superior to etidronate in preventing hip fractures. Other treatments include selective estrogen receptor modulators, strontium ranelate, denosumab, teriparatide, and hormone replacement therapy. Hip protectors and falls risk assessment may also be considered in management.

Dermatomyositis primarily results from an autoimmune disorder and is prevalent among women aged 50-70. Nevertheless, it can also be a paraneoplastic ailment, with ovarian, breast, and lung cancers being the most frequent underlying malignancies. It is crucial to contemplate the likelihood of an underlying tumor, particularly in elderly patients.

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.

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.

Common Causes of Knee Pain in Adolescents and Young Adults

Knee pain is a common complaint among adolescents and young adults, and can be caused by a variety of conditions. Here are some of the most common causes:

1. Patellar subluxation: This is a temporary but recurring lateral subluxation of the patella, which can cause the knee to give way or feel like it’s moving out of place. Conservative treatment with physiotherapy and knee braces is usually effective, but surgery may be necessary in some cases.

2. Chondromalacia patellae: This condition is caused by abnormal softening of the cartilage on the underside of the patella, and is a common cause of chronic knee pain in teenagers and young adults. Physiotherapy to alter patella-femoral alignment is the main treatment, along with analgesics and ice packs.

3. Osgood-Schlatter disease: This is a common cause of knee pain in young adolescents, particularly sporty boys. It is caused by overuse of quadriceps, and is characterized by pain inferior to the patella. Treatment is with simple analgesics and ice packs.

4. Osteochondritis dissecans: This condition is caused by separation of subchondral bone articular cartilage from the joint surface, and affects the knee in 75% of cases. It tends to present in teenagers and young adults, with vague and achy joint pain that is made worse by activity. Treatment depends on the severity of the condition, and may include surgery.

Overall, knee pain in adolescents and young adults can be caused by a variety of conditions, and treatment depends on the underlying cause and severity of the condition.

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.

Neuropathies: Causes and Symptoms

Neuropathies are a group of disorders that affect the peripheral nervous system. Here are some common causes and symptoms of different types of neuropathies:

Mononeuritis Multiplex:
This neuropathy affects two or more non-anatomically related peripheral nerves. It is caused by vasculopathy of the vasa nervorum or infiltration of the nerves. Common causes include diabetes mellitus, leprosy, polyarteritis nodosa, and rheumatoid arthritis. Symptoms include multiple concurrent peripheral nerve lesions without pain or paraesthesiae.

Peripheral Sensory Neuropathy:
This neuropathy is most commonly caused by diabetes mellitus (types 1 and 2) in the United Kingdom. It affects the sensory nerves and does not involve motor functions. Symptoms include aching pain, paraesthesiae, sensory loss, and muscle wasting.

Entrapment Neuropathy:
This neuropathy is caused by compression of peripheral nerves due to hypertrophied synovium or joint subluxation. It usually affects only one part of the body. The most common nerve compressions are cubital tunnel and carpal tunnel syndromes. Symptoms include aching pain, paraesthesiae, sensory loss, and muscle wasting.

Myasthenia Gravis (MG):
This autoimmune disorder affects the neuromuscular junction and causes fatigability of the muscle. It commonly affects the extraocular, bulbar, face, and neck muscles. Symptoms do not include pain or sensory loss, and wasting is only seen very late in the disease.

Multiple Sclerosis:
This autoimmune disorder affects the central nervous system and causes spasticity, ataxia, and paraesthesiae in the affected limbs. It commonly affects the optic nerve, causing optic neuritis. Peripheral nerve involvement is not seen.

Radial tunnel syndrome and lateral epicondylitis have similar presentations, but radial tunnel syndrome causes pain distal to the epicondyle and worsens with elbow extension and forearm pronation. This can make it challenging to differentiate between the two conditions. Radial tunnel syndrome is more common in athletes who frequently hyperextend their wrists or perform supination/pronation movements, such as gymnasts, racquet players, and golfers. Patients may also experience hand paraesthesia or wrist aching. Cubital tunnel syndrome, on the other hand, causes tingling and numbness in the 4th and 5th fingers, while olecranon bursitis results in swelling over the posterior elbow.

Understanding Lateral Epicondylitis

Lateral epicondylitis, commonly known as tennis elbow, is a condition that often occurs after engaging in activities that the body is not accustomed to, such as painting or playing tennis. It is most prevalent in individuals aged 45-55 years and typically affects the dominant arm. The primary symptom of this condition is pain and tenderness localized to the lateral epicondyle. The pain is often exacerbated by wrist extension against resistance with the elbow extended or supination of the forearm with the elbow extended. Episodes of lateral epicondylitis can last between 6 months and 2 years, with patients experiencing acute pain for 6-12 weeks.

To manage lateral epicondylitis, it is essential to avoid muscle overload and engage in simple analgesia. Steroid injections and physiotherapy are also viable options for managing the condition. By understanding the symptoms and management options for lateral epicondylitis, individuals can take the necessary steps to alleviate pain and discomfort associated with this condition.

Ankylosing spondylitis (AS) is a type of arthritis that is characterized by morning stiffness lasting more than 30 minutes, improvement of back pain with exercise but not rest, awakening due to back pain during the second half of the night, and alternating buttock pain. It is a seronegative spondyloarthropathy, meaning that the rheumatoid factor will be negative. Radiographically, sacroiliitis is often the first abnormality seen. ESR and CRP are usually raised, and HLA-B27 testing may provide supporting evidence. Lumbar disc prolapse with sciatica, rheumatoid arthritis, spinal stenosis, and Paget’s disease of bone are other conditions that may cause similar symptoms but have different characteristics and diagnostic criteria.

The bursae located in different parts of the body can become inflamed due to various reasons. The prepatellar bursa, situated in front of the patella, can become inflamed due to excessive friction between the skin and patella, which is commonly seen in people who work on their knees. This condition is often referred to as ‘Housemaid’s knee’. Inflammation of the infrapatellar bursae, located below the patella, can also occur due to similar friction between the skin, patellar tendon, and tibial tuberosity. The suprapatellar bursa, which is an extension of the knee joint cavity, can also become inflamed due to infection that can spread to involve the joint. The calcaneal bursae, located at the back of the calcaneus bone, near the Achilles’ tendon, can become inflamed due to overuse, such as in runners. This condition causes pain in the heel.

Knee problems are common among older adults, and it is important to be aware of the key features of each condition. Osteoarthritis of the knee is often seen in patients over 50 years of age who are overweight. This condition can cause severe pain, intermittent swelling, crepitus, and limited movement. Infrapatellar bursitis, also known as Clergyman’s knee, is associated with kneeling, while prepatellar bursitis, or Housemaid’s knee, is associated with more upright kneeling. Anterior cruciate ligament injuries may be caused by twisting of the knee, and patients may have heard a popping noise. Rapid onset of knee effusion and a positive draw test are also common features. Posterior cruciate ligament injuries may be caused by anterior force applied to the proximal tibia, such as during a car accident. Collateral ligament injuries can cause tenderness over the affected ligament and knee effusion. Meniscal lesions may be caused by twisting of the knee and can cause locking and giving-way, as well as tenderness along the joint line.

To identify the affected nerve, it is crucial to accurately diagnose the underlying condition. The patient’s symptoms, such as numbness and tingling in the thumb and middle finger (and possibly the radial half of the ring finger), suggest carpal tunnel syndrome. Additionally, the patient’s occupation involving computer use and hypothyroidism are risk factors for this condition. Carpal tunnel syndrome occurs when the median nerve is compressed at the wrist within the carpal tunnel.

Understanding Carpal Tunnel Syndrome

Carpal tunnel syndrome is a condition that occurs when the median nerve in the carpal tunnel is compressed. Patients with this condition typically experience pain or pins and needles in their thumb, index, and middle fingers. In some cases, the symptoms may even ascend proximally. Patients often shake their hand to obtain relief, especially at night.

During an examination, doctors may observe weakness of thumb abduction and wasting of the thenar eminence (not the hypothenar). Tapping on the affected area may cause paraesthesia, which is known as Tinel’s sign. Flexion of the wrist may also cause symptoms, which is known as Phalen’s sign.

Carpal tunnel syndrome can be caused by a variety of factors, including idiopathic reasons, pregnancy, oedema (such as heart failure), lunate fracture, and rheumatoid arthritis. Electrophysiology tests may show prolongation of the action potential in both motor and sensory nerves.

Treatment for carpal tunnel syndrome may include a 6-week trial of conservative treatments, such as corticosteroid injections and wrist splints at night. If symptoms persist or are severe, surgical decompression (flexor retinaculum division) may be necessary.

The correct diagnosis is lateral epicondylitis, which is caused by repetitive arm movements. The pain is typically more severe when the wrist is extended against resistance and the elbow is straightened. This description does not match the symptoms of anterior interosseous syndrome, carpal tunnel syndrome, or medial epicondylitis.

Lumbar spinal canal stenosis is often indicated by a history of progressive painful neurological deficit that improves when resting or leaning forward. This condition causes nerve root ischaemia due to inadequate microvascular blood flow to the spinal nerve roots, resulting in bilateral neuropathic pain and progressive deficit affecting the dermatomes and myotomes below the affected level. Leaning forward widens the canal, providing relief, while resting reduces the oxygen requirement of the nerve roots, allowing the ischaemia to slowly resolve. Neurological examination of the legs usually shows no abnormal findings as the symptoms are only brought on by consistent use of the nerve roots.

Osteoarthritis, on the other hand, is a degenerative arthropathy that typically affects large weight-bearing joints in the lower limbs, causing pain that rarely improves with rest and is not associated with a neurological deficit. It is usually unilateral and does not cause symmetrical symptoms.

Peripheral neuropathy can produce similar symptoms to spinal stenosis, but the pathology is not related to nerve use, and a deficit (usually sensory) would be detected on examination. The absence of such findings indicates that peripheral neuropathy is not the cause.

Peripheral vascular disease is the most likely differential for patients with spinal stenosis and symptoms of progressive leg pain that is relieved by rest. However, evidence of vascular insufficiency, such as absent distal pulses, ulceration or skin changes, would be present on examination if the condition were severe enough to cause symptoms after relatively short distances of walking. Additionally, leaning forward does not improve symptoms in peripheral vascular disease, only rest does.

Lumbar spinal stenosis is a condition where the central canal in the lower back is narrowed due to degenerative changes, such as a tumor or disk prolapse. Patients may experience back pain, neuropathic pain, and symptoms similar to claudication. However, one distinguishing factor is that the pain is positional, with sitting being more comfortable than standing, and walking uphill being easier than downhill. Degenerative disease is the most common cause, starting with changes in the intervertebral disk that lead to disk bulging and collapse. This puts stress on the facet joints, causing cartilage degeneration, hypertrophy, and osteophyte formation, which narrows the spinal canal and compresses the nerve roots of the cauda equina. MRI scanning is the best way to diagnose lumbar spinal stenosis, and treatment may involve a laminectomy.

Overall, lumbar spinal stenosis is a condition that affects the lower back and can cause a range of symptoms, including pain and discomfort. It is often caused by degenerative changes in the intervertebral disk, which can lead to narrowing of the spinal canal and compression of the nerve roots. Diagnosis is typically done through MRI scanning, and treatment may involve a laminectomy. It is important to note that the pain associated with lumbar spinal stenosis is positional, with sitting being more comfortable than standing, and walking uphill being easier than downhill.

Azathioprine is a medication that is broken down into mercaptopurine, which is an active compound that inhibits the production of purine. To determine if someone is at risk for azathioprine toxicity, a test for thiopurine methyltransferase (TPMT) may be necessary. Adverse effects of this medication include bone marrow depression, which can be detected through a full blood count if there are signs of infection or bleeding, as well as nausea, vomiting, pancreatitis, and an increased risk of non-melanoma skin cancer. It is important to note that there is a significant interaction between azathioprine and allopurinol, so lower doses of azathioprine should be used in conjunction with allopurinol. Despite these potential side effects, azathioprine is generally considered safe to use during pregnancy.

Nodal osteoarthritis is the usual cause of osteoarthritis in the hands, resulting from genetic factors. This type of arthritis leads to the development of Heberden’s nodes, which is swelling in the distal interphalangeal joints, and Bouchard’s nodes, which is swelling in the proximal interphalangeal joints. These nodes do not require any treatment. Pyogenic granuloma is a lesion that appears as a bright red or blood-crusted area, often following trauma, and is more common in children. A ganglion is a cystic lesion that occurs in the joint or synovial sheath of a tendon, most commonly in the wrist. A sebaceous cyst is a mobile, round cyst with a central punctum.

Clinical Diagnosis of Osteoarthritis

Osteoarthritis can be diagnosed clinically without the need for investigations, according to NICE guidelines. This means that a doctor can diagnose the condition based on the patient’s symptoms and physical examination alone. The guidelines state that if a patient is over 45 years old and experiences pain during exercise, but does not have morning stiffness or morning stiffness lasting more than 30 minutes, they can be diagnosed with osteoarthritis.

This approach to diagnosis is based on the fact that osteoarthritis is a degenerative condition that affects the joints, causing pain and stiffness. The symptoms tend to develop gradually over time, and are often worse after periods of inactivity or overuse. By focusing on the patient’s symptoms and history, doctors can make an accurate diagnosis and start treatment as soon as possible.

Overall, the clinical diagnosis of osteoarthritis is a simple and effective way to identify the condition in patients who meet the criteria. It allows for prompt treatment and management of symptoms, which can improve the patient’s quality of life and prevent further joint damage.

It is now recommended to offer allopurinol to all patients after their first gout attack, without delay. However, it is advised to wait until the inflammation has subsided before discussing urate-lowering therapy with the patient. If the attacks are too frequent, allopurinol can be considered even before the inflammation has completely settled. These recommendations are provided by the 2017 British Society for Rheumatology and NICE Clinical Knowledge Summaries.

Gout is caused by chronic hyperuricaemia and is managed acutely with NSAIDs or colchicine. Urate-lowering therapy (ULT) is recommended for patients with >= 2 attacks in 12 months, tophi, renal disease, uric acid renal stones, or prophylaxis if on cytotoxics or diuretics. Allopurinol is first-line ULT, with an initial dose of 100 mg od and titrated to aim for a serum uric acid of < 300 µmol/l. Lifestyle modifications include reducing alcohol intake, losing weight if obese, and avoiding high-purine foods. Consideration should be given to stopping precipitating drugs and losartan may be suitable for patients with coexistent hypertension.

The patient is experiencing an inguinal hernia, which is when abdominal contents protrude through the abdominal wall and create a lump in the groin area. This lump may be more noticeable when the patient coughs or strains, and can cause pain and discomfort. Inguinal hernias are typically located above and towards the middle of the pubic tubercle. Femoral hernias, which are less common, present similarly but are located lower and to the side of the pubic tubercle. A femoral artery aneurysm, lipoma, or saphena varix are not likely causes based on the patient’s symptoms and examination findings.

Understanding Inguinal Hernias

Inguinal hernias are the most common type of abdominal wall hernias, with 75% of cases falling under this category. They are more prevalent in men, with a 25% lifetime risk of developing one. The main feature of an inguinal hernia is a lump in the groin area, which is located superior and medial to the pubic tubercle. This lump disappears when pressure is applied or when the patient lies down. Discomfort and aching are common symptoms, which can worsen with activity, but severe pain is rare. Strangulation, a serious complication, is uncommon.

The clinical management of inguinal hernias involves treating medically fit patients, even if they are asymptomatic. A hernia truss may be an option for patients who are not fit for surgery, but it has little role in other patients. Mesh repair is the preferred method of treatment, as it is associated with the lowest recurrence rate. Unilateral hernias are generally repaired with an open approach, while bilateral and recurrent hernias are repaired laparoscopically. Patients can return to non-manual work after 2-3 weeks following an open repair and after 1-2 weeks following laparoscopic repair, according to the Department for Work and Pensions.

Complications of inguinal hernias include early bruising and wound infection, as well as late chronic pain and recurrence. While traditional textbooks describe the anatomical differences between indirect and direct hernias, this is not relevant to clinical management. Overall, understanding the features, management, and complications of inguinal hernias is crucial for proper diagnosis and treatment.

Understanding Lateral Epicondylitis: Symptoms and Diagnosis

Lateral epicondylitis, commonly known as tennis elbow, is a condition that affects the tendons of the forearm extensor muscles. It is often caused by repetitive activities such as typing, playing tennis, or manual work. While it is a self-limiting condition, it can cause significant pain and functional impairment.

Symptoms of lateral epicondylitis include tenderness on palpation of the bony prominence of the lateral epicondyle, reduced grip strength, and pain on resisted middle finger extension and wrist extension. Diagnosis is usually clinical, and management can be initiated at primary care.

If a patient presents with loss of sensation over the dorsum of the hand, it may be an indication to refer them to an orthopaedic surgeon to rule out differential diagnoses. However, normal sensation is a common finding in lateral epicondylitis.

Overall, understanding the symptoms and diagnosis of lateral epicondylitis is important for proper management and treatment of this condition.

Due to her positive family history, smoking, and excess alcohol intake, this woman is at a higher risk of developing osteoporosis. Therefore, it is recommended that she undergo a FRAX assessment without delay, rather than waiting until the age of 65 as typically recommended for women without such risk factors.

Assessing the Risk of Osteoporosis

Osteoporosis is a concern due to the increased risk of fragility fractures. To determine which patients require further investigation, NICE produced guidelines in 2012 for assessing the risk of fragility fracture. Women aged 65 years and older and men aged 75 years and older should be assessed, while younger patients should be assessed in the presence of risk factors such as previous fragility fracture, history of falls, and low body mass index.

NICE recommends using a clinical prediction tool such as FRAX or QFracture to assess a patient’s 10-year risk of developing a fracture. FRAX estimates the 10-year risk of fragility fracture and is valid for patients aged 40-90 years. QFracture estimates the 10-year risk of fragility fracture and includes a larger group of risk factors.

If the FRAX assessment was done without a bone mineral density (BMD) measurement, the results will be categorised into low, intermediate, or high risk. If the FRAX assessment was done with a BMD measurement, the results will be categorised into reassurance, consider treatment, or strongly recommend treatment. Patients assessed using QFracture are not automatically categorised into low, intermediate, or high risk.

NICE recommends reassessing a patient’s risk if the original calculated risk was in the region of the intervention threshold for a proposed treatment and only after a minimum of 2 years or when there has been a change in the person’s risk factors.

Psoriatic arthritis is a type of arthritis that can occur without prior psoriatic skin lesions and is often associated with dactylitis, also known as ‘sausage fingers’. HLA-B27 is commonly found in patients with psoriatic arthritis. Gout is unlikely in a woman under 60 and typically affects the big toe joint. Rheumatoid arthritis is also unlikely as it causes symmetrical polyarthritis and is associated with HLA-DRB1 rather than HLA-B27. Therefore, given the patient’s age, sex, dactylitis, and nail changes, psoriatic arthritis is a more likely diagnosis.

Psoriatic arthropathy is a type of inflammatory arthritis that is associated with psoriasis. It is classified as one of the seronegative spondyloarthropathies and is known to have a poor correlation with cutaneous psoriasis. In fact, it often precedes the development of skin lesions. This condition affects both males and females equally, with around 10-20% of patients with skin lesions developing an arthropathy.

The presentation of psoriatic arthropathy can vary, with different patterns of joint involvement. The most common type is symmetric polyarthritis, which is very similar to rheumatoid arthritis and affects around 30-40% of cases. Asymmetrical oligoarthritis is another type, which typically affects the hands and feet and accounts for 20-30% of cases. Sacroiliitis, DIP joint disease, and arthritis mutilans (severe deformity of fingers/hand) are other patterns of joint involvement. Other signs of psoriatic arthropathy include psoriatic skin lesions, periarticular disease, enthesitis, tenosynovitis, dactylitis, and nail changes.

To diagnose psoriatic arthropathy, X-rays are often used. These can reveal erosive changes and new bone formation, as well as periostitis and a pencil-in-cup appearance. Management of this condition should be done by a rheumatologist, and treatment is similar to that of rheumatoid arthritis. However, there are some differences, such as the use of monoclonal antibodies like ustekinumab and secukinumab. Mild peripheral arthritis or mild axial disease may be treated with NSAIDs alone, rather than all patients being on disease-modifying therapy as with RA. Overall, psoriatic arthropathy has a better prognosis than RA.

This presentation is typical of spinal stenosis. Although peripheral arterial disease is a possible alternative diagnosis, the pain relief factors and absence of abnormalities in the vascular examination suggest otherwise.

Lower back pain is a common issue that is often caused by muscular strain. However, it is important to be aware of potential underlying causes that may require specific treatment. Certain red flags should be considered, such as age under 20 or over 50, a history of cancer, night pain, trauma, or systemic illness. There are also specific causes of lower back pain that should be kept in mind. Facet joint pain may be acute or chronic, worse in the morning and on standing, and typically worsens with back extension. Spinal stenosis may cause leg pain, numbness, and weakness that is worse on walking and relieved by sitting or leaning forward. Ankylosing spondylitis is more common in young men and causes stiffness that is worse in the morning and improves with activity. Peripheral arterial disease may cause pain on walking and weak foot pulses. It is important to consider these potential causes and seek appropriate diagnosis and treatment.
