Mucocutaneous Lymph Node Syndrome

Pharyngitis - Article

ABSTRACT: Sore throat is one of the most common reasons for visits to family physicians. While most patients with sore throat have an infectious cause (pharyngitis), fewer than 20 percent have a clear indication for antibiotic therapy (i.e., group A beta-hemolytic streptococcal infection). Useful, well-validated clinical decision rules are available to help family physicians care for patients who present with pharyngitis. Because of recent improvements in rapid streptococcal antigen tests, throat culture can be reserved for patients whose symptoms do not improve over time or who do not respond to antibiotics.

Kawasaki Disease: Summary of the American Heart Association Guidelines - Article

ABSTRACT: Kawasaki disease is an acute vasculitis of childhood that predominantly affects the coronary arteries. The etiology of Kawasaki disease remains unknown, although an infectious agent is strongly suspected based on clinical and epidemiologic features. A genetic predisposition is also likely, based on varying incidences among ethnic groups, with higher rates in Asians. Symptoms include fever, conjunctival injection, erythema of the lips and oral mucosa, rash, and cervical lymphadenopathy. Some children with Kawasaki disease develop coronary artery aneurysms or ectasia, ischemic heart disease, and sudden death. Kawasaki disease is the leading cause of acquired heart disease among children in developed countries. This article provides a summary of the diagnostic and treatment guidelines published by the American Heart Association.

Kawasaki Disease - Article

ABSTRACT: Kawasaki disease is a leading cause of acquired heart disease among children in the United States and other developed countries. Most children who contract this illness are less than two years old, and 80 percent of affected children are younger than five years of age. A generalized vasculitis of unknown etiology, Kawasaki disease can cause coronary artery abnormalities, including coronary aneurysms. From 20 to 25 percent of untreated children develop coronary artery abnormalities, which may resolve or persist. These abnormalities are of particular concern because they can lead to thrombosis, evolve into segmental stenosis or, rarely, rupture. The principal cause of death from Kawasaki disease is myocardial infarction. The cause of the disease remains unknown, but epidemiologic investigations and the clinical presentation suggest a microbial agent. Diagnostic criteria, including fever and other principal features, have been established. In the acute phase of the disease, treatment with acetylsalicylic acid and intravenously administered immunoglobulin is directed at reducing inflammation of the coronary arteries and myocardium. Early recognition and treatment of Kawasaki disease can reduce the development of potentially life-threatening coronary artery abnormalities.
