We suggest to perform urine analysis and culture as the initial study for children with acute FUO and well clinical condition.

Urinary tract infection (UTI) is a frequent bacterial infection in children. The objective was to define the profile of children with UTI that consulted in a Chilean pediatric emergency department (PED). We reviewed 18302 consultants and identified 1173 patients in whom urine culture (UC) were obtained. UC was positive in 264 cases. UTI represented 1.34% from total consultants and 21% from whom UC were obtained. UTI was 1.78 times more frequent in girls. The most common clinical presentation was fever and urinary tract symptoms. In older than 2 years, urinary tract symptoms and previous UTI, was a risk factor for UTI. The most frequent organism isolated was Escherichia coli (86%). Nine percent of child with UTI were hospitalized. UTI is a frequent diagnosis in PED and is important to consider urinalysis in febrile infants, especially boys younger than 12 months.

Introduction: Kawasaki disease (KD) is a serious disease in children due to its potential complications and sequelae if not promptly and adequately managed. Objectives: To describe clinical and epidemiological characteristics of children hospitalized due to KD at a tertiary care center and identify risk factors for poor outcome. Patients and Methods: Retrospective and descriptive study of 32 medical records of patients hospitalized with diagnosis of KD at a tertiary care center of Santiago, Chile between February 1999 and May 2007. Results: The annual frequency was of 5 cases, mainly boys and during spring. The median age at diagnosis was 1.5 years and 87.5% of the children were younger than 5 years. Typical presentation prevailed in all ages (68,7%). Coronary artery affection, including dilatation or aneurisms, occurred in 21.9% of the cases, with aneurysms in 3 cases. All patients were treated with aspirin and intravenous immunoglobulin (IVIG); 4 patients required a second dose. No deaths were reported. The identifi ed risk factors for poor outcome were age older than 5 years and hypoalbuminemia. Conclusions: KD is an infrequent disease that mainly occurs in children younger than 5 years and with a typical presentation. There are risk factors associated with poor outcome.
