acute suppurative arthritis
arthritis(ar-thri'tis ) plural.arthritides [ arthro- + -itis]
Arthritis may result from infections (e.g., rheumatic fever, staphylococcal infections, gonorrhea, tuberculosis), metabolic disturbances (e.g., gout, calcium pyrophosphate crystal disease), multisystem autoimmune diseases (e.g., psoriasis, rheumatoid arthritis, systemic lupus erythematosus), neuropathies (e.g., Charcot's joint), joint trauma, or endocrine diseases (e.g., acromegaly). See: bursitis; monoarthritis; osteoarthritis; polyarthritis; rheumatism
Anti-inflammatory drugs, corticosteroids, monoclonal antibodies, antibiotics, joint aspiration, surgery, and occupational or physical therapies may play a role in the treating arthritis, depending on the cause and severity of the illness.

adjuvant arthritisAbbreviation: AA
It is treated with intravenous ceftriaxone. A tetracycline antibiotic is usually given at the same time to treat possible co-infection with Chlamydia species.
juvenile idiopathic arthritisAbbreviation: JIA
The preferred name for juvenile rheumatoid arthritis.
juvenile rheumatoid arthritisAbbreviation: JRA
Signs and symptoms depend on the type of JRA that is present.
Anti-inflammatory agents are the mainstay of palliation but have little effect on the outcome of the disease. Corticosteroids may have adverse effects on bone growth; therefore most rheumatologists try to minimize their use. Disease-modifying drugs, such as methotrexate or leflunomide are current mainstays of treatment. Hematopoietic stem cell transplantation may be used in specialized treatment centers. Surgery is used to release ankylosed joints once the child reaches physical maturity and is able to carry out vigorous rehabilitation. Physical and occupational therapy are needed to maintain muscle strength and joint range of motion to prevent contractures, deformities, and disability. Gait training and joint protection also are helpful. Splinting joints in correct alignment reduces pain and prevents contractures. Regularly scheduled slit-lamp examinations help in the early diagnosis of iridocyclitis, which should be managed by an ophthalmologist, usually with corticosteroids and mydriatics. Other extra-articular manifestations should be referred to medical and surgical specialists.
The child and family are instructed about the disease, treatment, and coping strategies, and are encouraged to express concerns. A well-balanced diet, regular exercise and rest periods, and avoidance of overexertion are encouraged. The child should be encouraged to be independent and involved in education and have an active social life. Moist heat helps relieve pain and stiffness. Placing the child in a warm bath, immersing painful hands and feet in pans of warm water for 10 min two to three times daily, or using daily whirlpool baths, a paraffin bath, or hot packs provide temporary relief of acute swelling and pain. Swimming and aerobic exercise in warm water are recommended to strengthen muscles and maintain mobility. Good posture and body mechanics are important; sleeping on a firm mattress without a pillow or with only a thin pillow is recommended to maintain proper body alignment. The patient should lie prone to straighten the hips and knees when resting or watching television. When braces or splints are required, their use is explained and demonstrated. Activities of daily living and playing provide opportunities to maintain mobility and incorporate therapeutic exercises using assistive and safety devices. The child with photophobia due to iridocyclitis should wear sunglasses. The child and family are referred to local and national support and information groups like the Arthritis Foundation (404-872-7100) (www.arthritis.org). Desired outcomes include the child's ability to achieve and maintain optimal health with joints that are movable, flexible, and free of deformity; to move with minimal or no discomfort; to engage in activities suitable to his or her interests, capabilities, and developmental level; and to perform self-care activities to maximum capabilities.

Factors implicated in the development and the severity of this disease include genetics (e.g., HLA haplotypes), autoimmune phenomena, and environmental influences.
Joint pains, morning stiffness, gelling, malaise, and fatigue are often present. Systemic disease marked by pleural effusions, pericarditis, pulmonary fibrosis, neuropathies, and ocular disorders may occu. Symptoms usually develop gradually over the course of several months but may begin abruptly in some patients.
Most rheumatologists recommend aggressive therapy with disease-modifying antirheumatic drugs (DMARDs) early in the course of the illness to prevent bony erosions and loss of joint function. Drugs in this class include agents like methotrexate. Nonsteroidal anti-inflammatory drugs, e.g., ibuprofen or corticosteroids are often prescribed for palliation. Many patients may continue to take low-dose corticosteroids for years, but the benefits of long-term steroid use must be weighed against the risks, such as diabetes, osteoporosis, and adrenal suppression. Gold compounds can be used, but they are weaker than DMARDs and newer agents. Newer agents include antibodies to tumor necrosis factor and other immunomodulatory drugs. Powerful immunosuppressive agents like cyclosporine, azathioprine, and mycophenolate may also be used. Combination therapies involving several agents from different classes can be used. Joint replacement surgery can be helpful for some patients. Homeopathic substances such as black currant (gamma linolenic acid) and fish oil have demonstrated efficacy in rheumatoid arthritis
All joints are assessed for inflammation, deformities, and contractures. The patient's ability to perform activities of daily living (ADLs) is evaluated. The patient is assessed for fatigue. Vital signs are monitored, and weight changes, pain (location, quality, severity, inciting and relieving factors), and morning stiffness (esp. duration) are documented. Use of moist heat is encouraged to relieve stiffness and pain. Prescribed anti-inflammatory and analgesic drugs are administered and evaluated; the patient is taught about the use of these medications. Patient response to all medications is evaluated, esp. after a change in drug regimen, and the patient and family are taught to recognize the purpose, schedule, and side effects of each. Over-the-counter drugs and herbal remedies may interact with prescribed drugs and should not be taken unless approved by physicians or pharmacists. Inflamed joints are occasionally splinted in extension to prevent contractures. Pressure areas are noted, and range of motion is maintained with gentle, passive exercise if the patient cannot comfortably perform active movement. Once inflammation has subsided, the patient is instructed in active range-of-motion exercise for specific joints. Warm baths or soaks are encouraged before or during exercise. Cleansing lotions or oils should be used for dry skin. The patient is encouraged to perform ADLs, if possible, allowing extra time as needed. Assistive and safety devices may be recommended for some patients. The patient should pace activities, alternate sitting and standing, and take short rest periods. Referral to an occupational or physical therapist helps keep joints in optimal condition as well as teaching the patient methods for simplifying activities and protecting joints. The importance of keeping PT/OT appointments and following home-care instructions should be stressed to both the patient and the family. A well-balanced diet that controls weight is recommended (obesity further stresses joints). Both patient and family should be referred to local and national support and information groups. Desired outcomes include cooperation with prescribed medication and exercise regimens, ability to perform ADLs, slowed progression of debilitating effects, pain control, and proper use of assistive devices. For more information and support, patient and family should contact the Arthritis Foundation (404-872-7100) (www.arthritis.org).
The primary site of infection is usually elsewhere, with joint infection occurring as the result of bacteremia or spread from osteomyelitis in an adjacent bone. The most common pathogen for those 16 to 40 years old is Neisseria gonorrhoeae; other common bacteria include Staphylococcus aureus, group B streptococci, and gram-negative bacilli such as Escherichia coli and Salmonella spp.
Suppurative arthritis is marked by an acutely painful, warm, swollen joint with limited range of motion and fever; the white blood cell count and erythrocyte sedimentation rates are increased. Except in gonococcal arthritis, only one joint is affected, most commonly the knee, hip, or shoulder.
Prompt treatment is necessary, including drainage of the joint and antimicrobial drug therapy (intravenous penicillinase-resistant penicillins and third-generation cephalosporins). The affected joint is supported with a sling or pillows, and the patient's pain is treated with mild opioids and nonsteroidal anti-inflammatory agents. Without vigorous treatment, significant joint destruction can occur.
