Summary • 6 year old male • Admitted for swelling of the right ear • Right ankle pain and swelling • Swelling of the nose • Swelling of the left ankle and left knee • Progressive joint swelling of both wrists and elbows
Arthritis • Inflammation of a joint space associated with joint swelling, pain, and limitation of motion • Results from infection, trauma, degenerative changes, or metabolic disturbances • Extra articular involvement with arthritis: Wegener’s Granulomatosis and Behcet’s Disease
Wegener’s Granulomatosis nasal/oral inflammation saddle nose deformity lung nodules/cavities microhematuria/red cell casts

Juvenile Idiopathic Arthritis more than 6 weeks of pain, swelling, and stiffness of joints involves metacarpophalangeal joints, proximal interphalangeal joints wrists, and metatarsophalangyeal joints involvement of cartilages such as the ears and nose nonerosive and asymmetric
Definition • Multisystemic disorder of unknown etiology affecting young adults • Recurrent, progressive episodes of inflammation affecting the cartilaginous structures, resulting in tissue damage • Elastic cartilage of the ears and nose, hyaline cartilage of peripheral joints, fibrocartilage of the axial skeleton, and cartilage of the tracheobronchial tree
Diagnostic Criteria (3 or more) recurrent chondritis of both auricles non erosive inflammatory polyarthritis chondritis of nose cartilage inflammation of ocular structures (keratitis, scleritis, episcleritis, uveitis) chondritis of the respiratory tract (laryngeal and/or tracheal cartilages) cochlear and/or vestibular damage causing sensorineural hearing loss, tinnitus and/or vertigo

Etiology • Remains unknown • Loss of basophilic staining of the cartilage matrix with perichondral inflammation of the cartilage • Perivascular mononuclear and polymorphonuclear cell infiltrates • Chondrocytes become vacuolated, necrotic and replaced by fibrous tissue
Etiology • Release of degradative enzymes • Immune mediated activation of chondrocytes and other inflammatory cells by cytokines including IL-1 and TNF-a • Autoimmunity
Prevalence • 3.5 cases/million in the US (Doros, A.A, October 2004) • 4 cases seen in PGH • Peak age for disease onset is the 5th decade • Female preponderance with ratio of 3:1
Clinical Features • Auricular chondritis • Joint pain with or without arthritis involving metacarpophalangeal, proximal interphalyngeal joints, wrists and knees • “Saddle nose” deformity • Scleritis, episcleritis, keratitis, and conjunctivitis
Clinical Features • Hoarseness, non productive cough, dyspnea, wheezing, and inspiratorystridor • Tenderness over thyroid cartilage and trachea • Aortic regurgitation and mitral regurgitation • Thoracic and abdominal aneurysm, myocarditis, pericarditis, silent myocardial infarction, paroxysmal atrial tachycardia, and 1st degree or even complete heart block
