Osteoarthritis: Degenerative Joint Disease
No questions yet
This comprehensive rheumatology topic provides Zambian tertiary nursing and medical students with detailed understanding of osteoarthritis (OA)—the most common joint disorder worldwide, representing a complex, multifactorial disease of the entire synovial joint organ involving articular cartilage degradation, subchondral bone remodeling, osteophyte formation, synovial inflammation, and periarticular muscle weakness. For Zambian …
Rheumatoid Arthritis: Autoimmune Synovitis
No questions yet
This comprehensive rheumatology topic provides Zambian tertiary nursing and medical students with detailed understanding of rheumatoid arthritis (RA)—a chronic, systemic, autoimmune inflammatory disorder primarily targeting synovial joints, characterized by symmetric polyarthritis, progressive joint destruction, and diverse extra-articular manifestations, associated with substantial morbidity, disability, and premature mortality if inadequately treated. For …
Gout: Crystal Arthropathy
No questions yet
This comprehensive rheumatology topic provides Zambian tertiary nursing and medical students with detailed understanding of gout—the most common inflammatory arthritis worldwide, caused by deposition of monosodium urate crystals in synovial joints and periarticular tissues in the setting of hyperuricemia, characterized by acute, excruciating, self-limiting flares, chronic tophaceous disease, and association …
Systemic Lupus Erythematosus: The Great Imitator
No questions yet
This comprehensive rheumatology topic provides Zambian tertiary nursing and medical students with detailed understanding of systemic lupus erythematosus (SLE)—the prototypical systemic autoimmune disease, characterized by loss of tolerance to nuclear antigens, production of diverse autoantibodies, immune complex deposition, and multi-organ involvement with extraordinarily heterogeneous clinical presentations that have earned it …
Spondyloarthritis: Axial and Peripheral
No questions yet
This comprehensive rheumatology topic provides Zambian tertiary nursing and medical students with detailed understanding of the spondyloarthritis (SpA) family—a group of interrelated, chronic inflammatory disorders sharing common genetic predisposition (HLA-B27), clinical features (axial inflammation, asymmetric oligoarthritis, enthesitis, dactylitis), and extra-articular manifestations (acute anterior uveitis, psoriasis, inflammatory bowel disease). For Zambian …
Septic Arthritis
No questions yet
Septic arthritis is an orthopaedic emergency—acute infection of synovial joint causing rapid, irreversible cartilage destruction within hours. For Zambian students, critical for emergency medicine, paediatrics, and orthopaedics. Pathophysiology: haematogenous seeding (most common), direct inoculation, contiguous spread. Bacteria proliferate in synovial fluid (excellent culture medium, low opsonins). Neutrophil infiltration → proteolytic …
Gout
No questions yet
Gout is the most common inflammatory arthritis—caused by monosodium urate crystal deposition in hyperuricaemia. For Zambian students, increasingly prevalent with nutritional transition, obesity, CKD. Pathophysiology: hyperuricaemia (>6.8mg/dL, saturation point) → crystal formation. Precipitants: rapid urate fluctuation, trauma, cooling, dehydration. Crystals activate NLRP3 inflammasome → IL-1β → neutrophil recruitment → acute …
Calcium Pyrophosphate Deposition Disease
No questions yet
Calcium pyrophosphate deposition (CPPD) disease—pseudogout—is crystal arthropathy caused by CPP crystal deposition in cartilage (chondrocalcinosis), with acute inflammatory flares mimicking gout. For Zambian students, important differential diagnosis in older adults. Pathophysiology: CPP crystals form in cartilage matrix, increased with aging, osteoarthritis, metabolic disorders (haemochromatosis, hyperparathyroidism, hypomagnesemia, hypophosphatasia). Crystal shedding triggers …
Ankylosing Spondylitis
No questions yet
Ankylosing spondylitis (AS) is the prototype spondyloarthritis—chronic inflammatory disease primarily affecting axial skeleton, causing sacroiliitis, spondylitis, and progressive spinal fusion. For Zambian students, frequently misdiagnosed as mechanical back pain; diagnostic delay 5-10 years common. Pathophysiology: genetic (HLA-B27 80-95% in Caucasians, 50-60% African populations), IL-23/IL-17 axis. Enthesitis—inflammation at tendon/ligament insertion into …
