Chronic musculoskeletal pain in children: part II. Rheumatic causes

Area of Science:

• Pediatric Rheumatology
• Primary Care Medicine
• Musculoskeletal Disorders

Background:

• Rheumatic diseases in children often present with musculoskeletal pain, requiring primary care physician awareness.
• Juvenile rheumatoid arthritis can manifest with painless joint inflammation and normal rheumatologic tests, necessitating ophthalmologist screening for uveitis.
• Spondyloarthropathies, acute rheumatic fever, Henoch-Schönlein purpura, and systemic lupus erythematosus are other childhood rheumatic conditions with distinct presentations.

Purpose of the Study:

• To equip primary care physicians with knowledge of common pediatric rheumatic diseases.
• To highlight key diagnostic features and potential complications of these conditions.
• To guide appropriate initial management and referral strategies for suspected rheumatic illnesses in children.

Main Methods:

• Review of clinical presentations of various childhood rheumatic diseases.
• Discussion of characteristic symptoms, physical findings, and relevant laboratory/radiologic tests.
• Emphasis on early recognition and timely referral for definitive diagnosis and management.

Main Results:

• Juvenile rheumatoid arthritis may present with painless arthritis and uveitis, requiring ophthalmologic evaluation.
• Spondyloarthropathies are associated with enthesitis and often positive HLA-B27 tests.
• Acute rheumatic fever follows streptococcal infection, while Henoch-Schönlein purpura can present with arthritis preceding a rash.

Conclusions:

• Primary care physicians play a vital role in the early identification of pediatric rheumatic diseases.
• Judicious use of diagnostic testing and prompt referral are essential for optimal patient outcomes.
• Nonsteroidal anti-inflammatory drugs and physical therapy can be early therapeutic interventions.
