Purpose

Escherichia coli sequence type (ST) 131, a multidrug-resistant clone causing extraintestinal infections, has rapidly become prevalent worldwide. However, the epidemiological and clinical features of pediatric infections are poorly understood. We aimed to explore the characteristics of ST131 Escherichia coli isolated from Korean children with urinary tract infections.

Methods

We examined 114 uropathogenic E. coli (UPEC) isolates from children hospitalized at Chung-Ang University...

Purpose : Kawasaki disease (KD) is a systemic vasculitis, a leading cause of pediatric acquired heart disease. Histopathological findings of coronary artery lesion (CAL) in KD indicate destruction of the coronary artery wall with diffuse vasculitis. Matrix metalloproteinases (MMPs) and their endogenous tissue inhibitors (TIMPs) might play central roles in this process. Special attention to MMP-9 has recently been emerging....
