Which one of the following conditions is associated with Kawasaki&;s syndrome? 
Select and explain. 
A. Acute rheumatic fever, B. Pulseless disease, C. Coronary aery aneurysm, D. Systemic lupus erythematosus
C: Coronary aery aneurysm
Answer: C: Coronary aery aneurysm 
Explanation: Kawasaki disease is an acute, febrile, multisystem disease of children. Although the disease is generally benign and self-limited, it is associated with coronary aery aneurysms in approximately 25% of cases.There is typical intimal proliferation and infiltration of the vessel wall with mononuclear cells. Beadlike aneurysms and thromboses may be seen along the aery. Other manifestations include pericarditis, myocarditis, myocardial ischemia and infarction, and cardiomegaly. High-dose IV g-globulin (2 g/kg as a single infusion over 10 h) together with aspirin (100 mg/kg per day for 14 days followed by 3-5 mg/kg per day for several weeks) have been shown to be effective in reducing the prevalence of coronary aery abnormalities when administered early in the course of the disease. Surgery may be necessary for Kawasaki disease patients who have giant coronary aery aneurysms or other coronary complications. Surgical treatment most commonly includes thromboendaerectomy, thrombus clearing, aneurysmal reconstruction, and coronary aery bypass grafting.Ref: Harrison&;s Principles of Internal Medicine; 19th edition; Chapter 385 The Vasculitis Syndromes; Page no: 2193
