[Polyarthritis - From symptoms to diagnosis]

Area of Science:

• Rheumatology
• Internal Medicine
• Clinical Diagnosis

Background:

• Polyarthritis is characterized by synovitic swelling in more than four joints.
• It is consistently caused by systemic diseases, not localized joint problems.
• Differential diagnosis is crucial as causes range from rheumatic to infectious diseases with distinct treatments.

Purpose of the Study:

• To provide a comprehensive overview of polyarthritis.
• To guide clinicians in patient history taking, clinical presentation assessment, and diagnostic investigations.
• To clarify the differential diagnosis for common diseases presenting as polyarthritis.

Main Methods:

• Review of clinical presentation and patient history elements relevant to polyarthritis.
• Analysis of diagnostic investigations for differentiating causes of polyarthritis.
• Exploration of differential diagnostic criteria to distinguish polyarthritis from osteoarthrosis and other conditions.

Main Results:

• Polyarthritis signifies a systemic process requiring broad diagnostic consideration.
• Key differentiating factors between various causes of polyarthritis are identified.
• Distinguishing polyarthritis from osteoarthrosis is highlighted as clinically significant.

Conclusions:

• Accurate diagnosis of polyarthritis relies on understanding its systemic nature.
• A systematic approach to patient history, clinical findings, and investigations is essential.
• Effective management of polyarthritis necessitates differentiating between its diverse underlying causes.
