Incidence and causes of urolithiasis in children between 0-2 years.

Background: Urolithiasis (UL) is a common problem in pediatric nephrology practice. About 9-23% of all pediatric UL cases consist of patients under 1 years old. The aim of the present study was to determine etiologic causes, clinical features and short term prognosis of urolithiasis in the first two years of life.

Can Urinary Nerve Growth Factor and Brain-Derived Neurotrophic Factor be used in the Diagnosis and Follow-Up of Voiding Dysfunction in Children?

Purpose: We investigated the utility of urinary nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) levels as non-invasive markers for diagnosis and evaluation of treatment efficacy in children with overactive bladder (OAB).

Materials And Methods: This prospective study included 24 children with OAB and 30 healthy controls. At the time of diagnosis, micturition disorder symptom scores (MDSS) were determined, blood and urine samples were collected, and anticholinergic therapy was initiated.

Assessment of vascular function in systemic onset juvenile idiopathic arthritis.

An increased incidence of cardiovascular disease has been found in rheumatic disorders. Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children. Prolonged immunological inflammatory process leads these patients to an early onset of atherosclerosis.

Familial Mediterranean fever in children from the Aegean region of Turkey: gene mutation frequencies and phenotype-genotype correlation.

Background/aim: Familial Mediterranean fever (FMF) is diagnosed by fever episodes with sterile peritonitis, arthritis, pleurisy, and erysipelas-like erythema. The relationship between phenotype and genotype in FMF has not been adequately explained. The aim of this study was to characterize the phenotype and genotype correlation in FMF.

Bioimpedance for assessing volume status in children with nephrotic syndrome.

Background/aim: The effectiveness of assessing volume load via bioimpedance in pediatric patients with nephrotic syndrome (NS) was investigated.

Materials And Methods: Patients with NS (n = 34) were compared with healthy controls (n = 20). The inferior vena cava index and inferior vena cava collapsibility index (IVCCI) scores were determined for all subjects.

Association of clearance of middle- and large-molecular-weight substance with arterial stiffness and left ventricular mass in children receiving renal replacement therapy.

Background: The prominent cause of mortality in children receiving dialysis treatment is cardiovascular diseases. Risk factors related to chronic renal disease, are effective in the development of cardiovascular diseases. The aim of study was to investigate cardiovascular system (CVS) involvement for functional and structural alterations in children receiving dialysis, and display any association between cardiovascular morbidity and uremic toxins.

Are we late for the diagnosis of acute kidney injury in the intensive care units in pediatric patients? A preliminary, retrospective observational study among 66 patients.

Background: The purposes of this study were to emphasize the importance of Risk, Injury, Failure, Loss, and End-Stage (RIFLE) classification in early diagnose and prognosis of acute kidney injury (AKI), and to evaluate the practicability of the RIFLE criteria in intensive care units.

Methods: Sixty-six patients applied acute peritoneal dialysis were included into the study. Patients having acute peritoneal dialysis within the first 24 hours of intensive care unit admission were named group 1, between 24-48 hours group 2, and those who had acute peritoneal dialysis 48 hours or more after admission to the intensive care unit were named group 3.

Cardiovascular functional and structural changes in children with primary hypertension.

Background: Primary hypertension in children is not a benign condition because of end-organ damage. Early investigations of cardiovascular effects rely on vascular structural and functional changes. We aimed to determine presence of early cardiovascular involvement in children with primary hypertension.

Success of continuous veno-venous hemodiafiltration treatment in children monitored in the intensive care units.

Introduction: As intensive care units (ICU) have improved, presence of multiple-organ dysfunctions in majority of patients with acute renal failure (ARF) has become clearer. To facilitate multi-organ support, continuous renal replacement therapy (CRRT) techniques have been developed. This study is the one that reports the experience on children including newborns receiving CRRT monitored in ICU.
