Treatment Options for Fibromyalgia Patients

Fibromyalgia is a chronic condition that causes widespread pain, increased sensitivity to pain, and psychological symptoms. Treatment options can be divided into generic and patient-focused treatments. Aerobic exercise is a first-line, generic treatment that has been shown to improve symptoms of pain and physical function. Cognitive behavioral therapy (CBT) is a patient-focused treatment that may be considered for patients with pain-related depression, anxiety, catastrophizing, and/or passive or active coping strategies. Anaerobic exercise should be avoided as it may increase inflammation and oxidative stress. Duloxetine and pregabalin are pharmacotherapy options for patients with severe pain or sleep disturbance, but only after non-pharmacological treatments have failed. It is important to tailor treatment to each patient’s individual needs.

Treatment Options for Fibromyalgia Patients

Differentiating Knee Conditions: A Case-Based Approach

A patient presents with a red, tender, and inflamed knee. The differential diagnosis includes prepatellar bursitis, osteoarthritis, localised cellulitis, rheumatoid arthritis, and gout.

prepatellar bursitis, also known as housemaid’s knee, carpet layer’s knee, or nun’s knee, is often caused by repetitive knee trauma. Treatment involves non-steroidal anti-inflammatory agents and local corticosteroid injection. Septic bursitis requires appropriate antibiotic cover and drainage.

Osteoarthritis is a diagnosis of exclusion and does not typically cause a red, tender, inflamed knee. Knee aspirate in this case would not show white cells.

Localised cellulitis may result in erythema but is unlikely to cause knee swelling. Knee aspirate in this case would not show white cells.

Rheumatoid arthritis is unlikely to present in men of this age and typically affects small joints of the fingers, thumbs, wrists, feet, and ankles.

Gout can be diagnosed through the presence of negatively birefringent crystals seen on joint microscopy.

In conclusion, a thorough evaluation of the patient’s symptoms and appropriate diagnostic tests are necessary to differentiate between these knee conditions.

Common Hand and Wrist Pathologies

The hand and wrist are common sites of pathology, particularly in postmenopausal women. Osteoarthritis frequently affects the first carpometacarpal joint, causing tenderness, stiffness, crepitus, swelling, and pain on thumb abduction. This can lead to squaring of the hand, radial subluxation of the metacarpal, and atrophy of the thenar muscles.

Scaphoid fractures are also relatively common, often resulting from a fall onto an outstretched hand. The proximal portion of the scaphoid lacks its own blood supply, which can lead to avascular necrosis if a fracture isolates it from the rest of the bone. This produces pain and tenderness on the radial side of the wrist, typically in the anatomical snuffbox, worsened by wrist movement.

De Quervain’s tenosynovitis is another common pathology, characterized by stenosing tenosynovitis of the first dorsal compartment of the wrist. It presents with pain, swelling, and tenderness on the radial aspect of the wrist. Treatment typically involves splinting, with or without corticosteroid injection.

Understanding the Diagnosis of Polymyalgia Rheumatica

Polymyalgia rheumatica (PMR) is a condition that causes pain and stiffness in proximal muscle groups, often accompanied by systemic symptoms. While other potential diagnoses such as infections or neoplasia should be considered, PMR is typically characterised by raised levels of inflammatory markers, particularly erythrocyte sedimentation rate (ESR). Treatment with corticosteroids usually results in rapid improvement, and lack of response to steroids may indicate a need to re-evaluate the diagnosis. Autoantibody screening and nerve conduction velocity tests are not helpful in diagnosing PMR, while muscle biopsy may be performed to exclude polymyositis. A temporal artery biopsy may be considered if the patient has symptoms of giant cell arthritis.

Osteoarthritis in the Hand and Elbow

Osteoarthritis (OA) is a prevalent form of arthritis that commonly affects the hand, particularly the joints. The joints may exhibit several deformities, including the development of small bone spurs called nodes. These nodes are referred to as Heberden’s nodes when they occur at the joint next to the fingernail and Bouchard’s nodes when they occur at the middle joints. The base of the thumb may also appear squared off, accompanied by swelling and tenderness. Soft tissue laxity can result in instability at the base of the thumb.

In contrast, elbow OA is relatively uncommon.

Differentiating Arthritides: Understanding Clinical and Laboratory Findings

Arthritis is a common condition that affects the joints, and it can be challenging to distinguish between the various types that exist. However, by considering the patient’s medical history, physical examination, and laboratory findings, clinicians can make an accurate diagnosis.

For instance, psoriatic arthritis is an inflammatory subtype of arthritis that often affects the DIP joints, sausage digits, and nails. The classic X-ray finding of psoriatic arthritis is the pencil in a cup appearance, although it is not specific to the disease. In contrast, rheumatoid arthritis is characterized by PIP and MCP joint involvement, wrist and cervical spine pain, and positive rheumatoid factor and anti-CCP antibodies.

Septic arthritis is a medical emergency that usually involves large joints and is associated with high fever, chills, and rapid joint destruction. Synovial fluid analysis may reveal Gram-positive cocci in cases of septic arthritis caused by Staphylococcus aureus.

Osteoarthritis, on the other hand, is a degenerative joint disease that is associated with subchondral cyst formation, joint space narrowing, and osteophyte formation. It typically affects the DIP and PIP joints and large weight-bearing joints, but it is not an inflammatory arthritis.

In summary, understanding the clinical and laboratory findings associated with different types of arthritis is crucial for accurate diagnosis and appropriate management.

Diagnostic Markers for Polymyalgia Rheumatica and Temporal arthritis

Polymyalgia rheumatica and temporal arthritis are inflammatory conditions that can cause significant morbidity if left untreated. Here are some diagnostic markers that can help support or rule out these conditions:

Plasma viscosity: A raised plasma viscosity can support a diagnosis of polymyalgia rheumatica with temporal arthritis, but it is a nonspecific inflammatory marker.

Creatine kinase: A raised creatine kinase is not supportive of a diagnosis of polymyalgia rheumatica or temporal arthritis.

Monospot test: A positive monospot test is supportive of a diagnosis of Epstein–Barr virus (EBV), but not polymyalgia rheumatica or temporal arthritis.

Whole cell count (WCC): A raised WCC is not supportive of a diagnosis of polymyalgia rheumatica or temporal arthritis.

Bence Jones proteins: Presence of Bence Jones protein is supportive of a diagnosis of multiple myeloma, but not polymyalgia rheumatica or temporal arthritis.

If temporal arthritis is suspected, immediate treatment with prednisolone is crucial to prevent permanent loss of vision. A temporal artery biopsy can confirm the diagnosis.

Behçet’s Syndrome: A Multisystem Disorder with Recurrent Oral and Genital Ulcerations

Behçet’s syndrome is a multisystem disorder that primarily affects young people from the Mediterranean region, the Middle East, and the Far East. The syndrome is characterized by recurrent oral and genital ulcerations, as well as ocular involvement. The main pathologic lesion is systemic perivasculitis with early neutrophil infiltration and endothelial swelling. In some patients, vasculitis of the vasa vasorum can result in the formation of pseudo-aneurysms. Anti-Saccharomyces cerevisiae antibodies are present in patients with Behçet’s syndrome. The recurrent aphthous ulcerations are essential for the diagnosis, and a non-specific skin inflammatory reactivity to any scratches or intradermal saline injection (pathergy test) is a common and specific manifestation. Genital ulcers are painful, do not affect the glans penis or urethra, and produce scrotal scars. Thromboembolic events are a component of the disease itself, with superficial or deep peripheral vein thrombosis seen in 30% of patients. Pulmonary emboli are a rare but possible complication.

Other possible diagnoses, such as extra intestinal Crohn’s disease, occult malignancy, systemic lupus erythematosus (SLE), and rheumatoid arthritis, can be ruled out based on the absence of certain clinical features and the presence of anti-Saccharomyces cerevisiae antibodies.

Understanding HLA and Autoimmune Diseases

HLA-B27 is a genetic marker associated with ankylosing spondylitis, an autoimmune disease that primarily affects the spine. This disease is more common in males and typically presents in the 20s and 30s. Other autoimmune manifestations, such as anterior uveitis, can also occur in individuals with HLA-B27. Additionally, young men with this genetic marker may be prone to reactive arthritis after chlamydia or gonorrhoeal urethritis.

Rheumatoid factor, on the other hand, is not associated with HLA-B27 or ankylosing spondylitis. While stiffness that improves with exercise may be seen in rheumatoid arthritis, this disease typically affects peripheral joints and does not lead to calcification of the anterior spinal ligament.

Other HLA markers are associated with different autoimmune diseases. HLA-DR3 is linked to type 1 diabetes mellitus, HLA-DR5 is associated with pernicious anaemia and Hashimoto’s thyroiditis, and HLA-B8 is linked to Graves’ disease. Understanding these genetic markers can aid in the diagnosis and management of autoimmune diseases.

Treatment Options for Acute Gout Flare in a Patient with Peptic Ulcer Disease

When managing an acute gout flare in a patient with a history of peptic ulcer disease, it is important to consider the potential risks and benefits of different treatment options. Colchicine and non-steroidal anti-inflammatory drugs (NSAIDs) are both effective first-line treatments, but NSAIDs should be used with caution in patients with a history of peptic ulcer disease. If NSAIDs are used, proton-pump cover should be provided for gastric protection. Allopurinol should not be started until after the acute attack has been resolved, and paracetamol may be used as an adjunct for pain relief but would not treat the underlying cause of pain. Prednisolone may be used in patients unable to tolerate NSAIDs or colchicine, but there is no contraindication to a trial of oral colchicine in this patient. Overall, the choice of treatment should be individualized based on the patient’s medical history and preferences.
