Abstract:
A 67-year-old man presented with myalgia, muscle atrophy, and a history of seronegative polyarthritis. Blood tests showed inflammation but no hematologic or immunologic abnormalities. Muscle biopsy revealed no vasculitis or myositis but Tropheryma whipplei was detected by polymerase chain reaction in muscle, blood, and duodenum specimens; this was confirmed by immunohistochemistry. Ceftriaxone led to clinical improvement. Although rare, Whipple's disease should be considered in the differential diagnosis of diffuse myopathy.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
