Mental disorders and quality of life in pediatric patients with chronic kidney disease.

In the last decades there was a striking improvement in survival of children with chronic kidney disease. As life expectancy has increased in children with CKD, concern has risen about its physical, psychological, and social consequences. The aim of this study was to perform a review of the psychological consequences of CKD in the pediatric population, with the focus on mental disorders and on quality of life.

Predictive factors of chronic kidney disease in severe vesicoureteral reflux.

The aim of this retrospective cohort study was to evaluate independent predictive factors of chronic kidney disease (CKD) in children with severe bilateral primary vesicoureteral reflux (VUR). Between 1970 and 2004, 184 patients were diagnosed with VUR (grades III-V) and were systematically followed up at a single tertiary renal unit. CKD was defined as estimated glomerular filtration rate <75 ml/min per 1.

Clinical course of 735 children and adolescents with primary vesicoureteral reflux.

The purpose of this retrospective cohort study was to report the clinical course of children with primary vesicoureteral reflux (VUR). Between 1970 and 2004, 735 patients were diagnosed with VUR and were systematically followed in a single tertiary renal unit. Patients were followed up for a mean time of 76 months (6 months to 411 months).

Gender and vesico-ureteral reflux: a multivariate analysis.

The aim of this retrospective cohort study was to describe the characteristics of patients with primary vesico-ureteral reflux (VUR) with special attention to gender-specific differences. Between 1970 and 2004, 735 patients were diagnosed with VUR and were systematically followed in a single tertiary renal unit. The following variables were analyzed: race, age at diagnosis, clinical presentation, weight and height Z-score, unilateral/bilateral reflux, VUR grade, renal damage, severity of renal damage, constipation, and dysfunctional voiding.

Clinical course of prenatally detected primary vesicoureteral reflux.

The purpose of this study was to report the clinical course of medium-long-term follow-up of children with prenatally detected vesicoureteral reflux (VUR). Between 1986 and 2004, 53 (41 males) children with VUR detected by investigation of prenatal hydronephrosis were followed up for a mean time of 66 months (range: 6-200 months). Newborns were investigated by ultrasound, voiding cystourethrogram (VCUG) and DMSA scan.

[Urinary excretion of calcium, uric acid and citrate in healthy children and adolescents].

Objective: To obtain regional reference values for calcium, uric acid and citrate urinary excretion and establish a correlation between those excretions in 24-hour urine sample and single urine sample for their use in clinical practice.

Methods: A hundred and twenty-five healthy children and adolescents were randomly chosen and submitted to the following protocol: clinical examination, biochemical analysis of blood, blood cell count, parathormone, 24-hour urine, fasting urine sample and stool test.

Results: The maximum value of calcium excretion in 24-hour urine was 3.
