[Recommendations on diagnosis, management and study of the urinary tract infection in pediatrics. Nephrology Branch of the Chilean Society of Pediatrics. Part 1].

Urinary tract infection (UTI) is one of the most frequent bacterial infection in pediatrics. However, its diagnosis and management can be complicated due to the nonspecific clinical presentation, the difficulty of exams interpretation, especially in younger children, and an uncertain prognosis regar ding renal damage. In recent years, significant worldwide change has come in treatment, diagnosis, and images studies, we have decided to update the current recommendations on UTI management published by the Pediatric Nephrology branch of Chilean Pediatrics Society in previous years.

Urinary tract infection (UTI) is one of the most frequent bacterial infections in pediatrics, however, its diagnosis and management can be complicated due to the nonspecific clinical presentation, the difficulty of exams interpretation, especially in the younger group, and due to an uncertain progno sis regarding kidney damage. In recent years, due to evidence-based medicine contribution, there has been a significant worldwide change in treatment, diagnosis and imaging studies that have been performed to date, arising the need for update the current recommendations on UTI management published by the Pediatric Nephrology branch of the Chilean Society of Pediatrics in previous years. The purpose of these recommendations is to reduce the variability of clinical practice in management of UTI in our pediatric population, favoring diagnostic and therapeutic interventions are carried out in the most appropriate way, improving detection and management of structural pathology and others risk factors for kidney damage, avoiding unnecessary actions in children at low risk.

[Hemolytic-uremic syndrome in Chile: clinical features, evolution and prognostic factors].

Background: Hemolytic-uremic syndrome (HUS) is characterized by acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia.

Aim: To describe the characteristics of patients with the diagnosis of HUS in Chile, and to identify the most reliable early predictors of morbidity and mortality.

Material And Methods: The clinical records of patients with HUS aged less than 15 years, attended between January 1990 and December 2003 in 15 hospitals, were reviewed.
