The patient is experiencing symptoms of osteomalacia, such as bone pain, tenderness, and proximal myopathy leading to a waddling gait. Pseudofractures may also be present. Secondary hyperparathyroidism and hypocalcemia should be ruled out, and vitamin D supplementation is the primary treatment. Duchenne muscular dystrophy, osteoclastoma, and Paget’s disease are unlikely diagnoses due to the patient’s age, symptoms, and presentation.

Understanding Osteomalacia

Osteomalacia is a condition that occurs when the bones become soft due to low levels of vitamin D, which leads to a decrease in bone mineral content. This condition is commonly seen in adults, while in growing children, it is referred to as rickets. The causes of osteomalacia include vitamin D deficiency, malabsorption, lack of sunlight, chronic kidney disease, drug-induced factors, inherited conditions, liver disease, and coeliac disease.

The symptoms of osteomalacia include bone pain, muscle tenderness, fractures, especially in the femoral neck, and proximal myopathy, which may lead to a waddling gait. To diagnose osteomalacia, blood tests are conducted to check for low vitamin D levels, low calcium and phosphate levels, and raised alkaline phosphatase levels. X-rays may also show translucent bands known as Looser’s zones or pseudofractures.

The treatment for osteomalacia involves vitamin D supplementation, with a loading dose often needed initially. Calcium supplementation may also be necessary if dietary calcium intake is inadequate. Understanding the causes, symptoms, and treatment options for osteomalacia is crucial in managing this condition effectively.

The most specific test for limited cutaneous systemic sclerosis among patients with systemic sclerosis is the anti-centromere antibodies.

Understanding Systemic Sclerosis

Systemic sclerosis is a condition that affects the skin and other connective tissues, but its cause is unknown. It is more common in females, with three patterns of the disease. Limited cutaneous systemic sclerosis is characterised by Raynaud’s as the first sign, affecting the face and distal limbs, and associated with anti-centromere antibodies. CREST syndrome is a subtype of limited systemic sclerosis that includes Calcinosis, Raynaud’s phenomenon, oEsophageal dysmotility, Sclerodactyly, and Telangiectasia. Diffuse cutaneous systemic sclerosis affects the trunk and proximal limbs, associated with scl-70 antibodies, and has a poor prognosis. Respiratory involvement is the most common cause of death, with interstitial lung disease and pulmonary arterial hypertension being the primary complications. Renal disease and hypertension are also possible complications, and patients with renal disease should be started on an ACE inhibitor. Scleroderma without internal organ involvement is characterised by tightening and fibrosis of the skin, manifesting as plaques or linear. Antibodies such as ANA, RF, anti-scl-70, and anti-centromere are associated with different types of systemic sclerosis.

Felty’s syndrome is a medical condition where a patient with rheumatoid arthritis experiences splenomegaly and neutropenia. This is caused by hypersplenism, which destroys blood cells and leads to neutropenia or pancytopenia. While methotrexate use can cause neutropenia, it is not typically associated with splenomegaly.

Rheumatoid arthritis (RA) is a condition that can lead to various complications beyond joint pain and inflammation. These complications can affect different parts of the body, including the respiratory system, eyes, bones, heart, and immune system. Some of the respiratory complications associated with RA include pulmonary fibrosis, pleural effusion, and bronchiolitis obliterans. Eye-related complications may include keratoconjunctivitis sicca, scleritis, and corneal ulceration. RA can also increase the risk of osteoporosis, ischaemic heart disease, infections, and depression. Less common complications may include Felty’s syndrome and amyloidosis.

It is important to note that these complications may not affect all individuals with RA and the severity of the complications can vary. However, it is essential for individuals with RA to be aware of these potential complications and to work closely with their healthcare providers to manage their condition and prevent or address any complications that may arise. Regular check-ups and monitoring of symptoms can help detect and manage any complications early on.

Atypical stress fractures are more likely to occur in patients taking bisphosphonates.

The correct medication in this case is alendronic acid, which is being used to treat bony metastases in a patient with breast cancer who is also receiving Herceptin. Bony pain or signs of fractures in a patient with a history of cancer should raise suspicion of increased activity of bony metastases. While investigations ruled out bony metastases to the femurs, other causes must be considered. Prolonged use of bisphosphonates, such as alendronic acid, can decrease the activity of osteoclasts and inhibit bone remodeling, leading to changes and damage in the bone that would normally have been repaired. This can result in brittle bones and increased fragility, which can lead to atypical stress fractures.

Furosemide, Herceptin, and sertraline are not associated with an increased risk of atypical stress fractures.

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.

Hand osteoarthritis is often characterized by stiffness that worsens after long periods of inactivity, such as sleep. This stiffness typically lasts only a few minutes, unlike inflammatory arthritis conditions like rheumatoid arthritis, which can cause morning stiffness lasting up to an hour. One distinctive feature of hand osteoarthritis is squaring of the thumbs, specifically in the carpometacarpal joint. Pain associated with hand osteoarthritis tends to be worse with activity and relieved by rest. Ankylosing spondylitis primarily affects the spine and can also cause morning stiffness, but this stiffness is typically felt in the back rather than the hands. Osteoporosis itself does not cause pain or stiffness, but it can lead to bone fractures and is more commonly associated with large joint osteoarthritis than hand osteoarthritis. Reiter’s syndrome, also known as reactive arthritis, is characterized by conjunctivitis, urethritis, and oligoarthritis, typically affecting the knee. Squaring of the thumbs is not a characteristic feature of rheumatoid arthritis, which is instead associated with swan-neck deformity, ulnar deviation, and subluxation of the carpal bones, among other symptoms.

Understanding Osteoarthritis of the Hand

Osteoarthritis of the hand, also known as nodal arthritis, is a condition that occurs when the cartilage at synovial joints is lost, leading to the degeneration of underlying bone. It is more common in women, usually presenting after the age of 55, and may have a genetic component. Risk factors include previous joint trauma, obesity, hypermobility, and certain occupations. Interestingly, osteoporosis may actually reduce the risk of developing hand OA.

Symptoms of hand OA include episodic joint pain, stiffness that worsens after periods of inactivity, and the development of painless bony swellings known as Heberden’s and Bouchard’s nodes. These nodes are the result of osteophyte formation and are typically found at the distal and proximal interphalangeal joints, respectively. In severe cases, there may be reduced grip strength and deformity of the carpometacarpal joint of the thumb, resulting in fixed adduction.

Diagnosis is typically made through X-ray, which may show signs of osteophyte formation and joint space narrowing before symptoms develop. While hand OA may not significantly impact a patient’s daily function, it is important to manage symptoms through pain relief and joint protection strategies. Additionally, the presence of hand OA may increase the risk of future hip and knee OA, particularly for hip OA.

The optimal surgical approach for intertrochanteric (extracapsular) proximal femoral fracture is the use of dynamic hip screws. These screws are considered dynamic due to their ability to tighten as the bone heals. Hemiarthroplasty is not the preferred option for this type of fracture, as it is typically reserved for displaced intracapsular fractures in patients with significant comorbidities or immobility. Internal fixation is also not the preferred approach, as it is typically used for undisplaced intracapsular fractures in mobile patients without serious comorbidities. Intramedullary nails are not the preferred approach for intertrochanteric fractures, as they are typically used for subtrochanteric fractures.

Hip fractures are a common occurrence, particularly in elderly women with osteoporosis. The femoral head’s blood supply runs up the neck, making avascular necrosis a potential risk in displaced fractures. Symptoms of a hip fracture include pain and a shortened and externally rotated leg. Patients with non-displaced or incomplete neck of femur fractures may still be able to bear weight. Hip fractures can be classified as intracapsular or extracapsular, with the Garden system being a commonly used classification system. Blood supply disruption is most common in Types III and IV fractures.

Intracapsular hip fractures can be treated with internal fixation or hemiarthroplasty if the patient is unfit. Displaced fractures are recommended for replacement arthroplasty, such as total hip replacement or hemiarthroplasty, according to NICE guidelines. Total hip replacement is preferred over hemiarthroplasty if the patient was able to walk independently outdoors with the use of a stick, is not cognitively impaired, and is medically fit for anesthesia and the procedure. Extracapsular hip fractures can be managed with a dynamic hip screw for stable intertrochanteric fractures or an intramedullary device for reverse oblique, transverse, or subtrochanteric fractures.

The symptoms and high ESR levels suggest that the patient may have polymyalgia rheumatica, with the added indication of painful mastication pointing towards possible temporal arthritis. Immediate treatment with high doses of steroids is crucial. To distinguish between polymyalgia rheumatica and statin-induced myopathy, ESR levels are typically measured. A significantly elevated ESR level would indicate polymyalgia rheumatica, while a normal ESR level would suggest statin myopathy.

Polymyalgia Rheumatica: A Condition of Muscle Stiffness in Older People

Polymyalgia rheumatica (PMR) is a common condition that affects older people. It is characterized by muscle stiffness and elevated inflammatory markers. Although it is closely related to temporal arthritis, the underlying cause is not fully understood, and it does not appear to be a vasculitic process. PMR typically affects patients over the age of 60 and has a rapid onset, usually within a month. Patients experience aching and morning stiffness in proximal limb muscles, along with mild polyarthralgia, lethargy, depression, low-grade fever, anorexia, and night sweats.

To diagnose PMR, doctors look for raised inflammatory markers, such as an ESR of over 40 mm/hr. Creatine kinase and EMG are normal. Treatment for PMR involves prednisolone, usually at a dose of 15 mg/od. Patients typically respond dramatically to steroids, and failure to do so should prompt consideration of an alternative diagnosis.

ANCA Associated Vasculitis: Common Findings and Management

Anti-neutrophil cytoplasmic antibodies (ANCA) are associated with small-vessel vasculitides such as granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, and microscopic polyangiitis. ANCA associated vasculitis is more common in older individuals and presents with renal impairment, respiratory symptoms, systemic symptoms, and sometimes a vasculitic rash or ear, nose, and throat symptoms. First-line investigations include urinalysis, blood tests for renal function and inflammation, ANCA testing, and chest x-ray. There are two main types of ANCA – cytoplasmic (cANCA) and perinuclear (pANCA) – with varying levels found in different conditions. ANCA associated vasculitis should be managed by specialist teams and the mainstay of treatment is immunosuppressive therapy.

To manage plantar fasciitis, it is recommended to start with rest, stretching, and weight loss if the patient is overweight. Stretching exercises targeting the plantar fascia and Achilles tendon should be done three times a day. Orthotics and NSAIDs can be used, but only after trying the initial measures. It is important to note that the patient has asthma, so prescribing ibuprofen would not be appropriate. While a 6 week review is appropriate, it should also include monitoring weight loss as a key factor in managing the condition. Therefore, weight loss should be considered as the best initial step, given the patient’s BMI of 29.

Understanding Plantar Fasciitis

Plantar fasciitis is a prevalent condition that causes heel pain in adults. The pain is typically concentrated around the medial calcaneal tuberosity, which is the bony bump on the inside of the heel. This condition occurs when the plantar fascia, a thick band of tissue that runs along the bottom of the foot, becomes inflamed or irritated.

To manage plantar fasciitis, it is essential to rest the feet as much as possible. Wearing shoes with good arch support and cushioned heels can also help alleviate the pain. Insoles and heel pads may also be beneficial in providing additional support and cushioning. It is important to note that plantar fasciitis can take time to heal, and it is crucial to be patient and consistent with treatment. By taking these steps, individuals can effectively manage their plantar fasciitis and reduce their discomfort.

Osteomalacia may be indicated by bone pain, tenderness, and proximal myopathy (resulting in a waddling gait), as well as low levels of calcium and phosphate and elevated alkaline phosphatase.
