Unusual bilateral obstructive uropathy with kidney failure in an adolescent with ulcerative colitis.

Extrarenal manifestation and complications of inflammatory bowel disease may be detected in a significant number of patients. It is known that the genitourinary tract may be affected but data from childhood population are scarce. We present an unusual bilateral obstruction of ureters, inflammation of bladder wall and vesicoureteral reflux in a boy with ulcerative colitis.

Cyclosporine A - treated nephrotic children show impaired vasodilatation but no autonomic neuropathy.

Introduction: The aim of the study was to determine the effect of long-term cyclosporine A (CsA) treatment in children with idiopathic nephrotic syndrome on autonomic nerve function and peripheral blood flow assessed with thermography.

Material And Methods: The study group consisted of 19 nephrotic children treated with cyclosporine A compared to 16 healthy children. The assessment of blood flow was made based on the results of thermographic measurements during the cold stress test by an infrared radiation registering camera.

[Difficulties in renal osteodystrophy treatment in patient undergoing long-term renal replacement therapy--a case study].

Abnormal mineral metabolism and altered bone structure and composition occur early in the course of chronic kidney disease. We present difficulties in renal osteodystrophy treatment in patient undergoing renal replacement therapy for twenty two years (dialysis, transplant, dialysis), which is not in the waiting list for kidney transplant (patient disagreement). Due to failure of conventional therapy of hyperparathyroidism (calcium, phosphate binders, vitamin D) he was needed parathyroidectomy twice.

[Calcium-phosphate disturbances in dialysed children and adolescents--one centre analysis between 1991-2008].

Unlabelled: Disturbances of calcium-phosphate metabolism are one of the most prominent complications of chronic kidney disease with high impact on cardiovascular complications and outcome. The aim of the study was to assess the clinical efficacy of CKD-related calcium-phosphate homeostasis treatment in children and adolescents on chronic dialysis in a tertiary reference centre between 1991 to 2008.

Material And Methods: Study group consisted of 81 subjects (29F, 52M): 40 hemodialysis and 41 peritoneal dialysis patients (aged at start of dialysis: 1m.

[Reflux and obstructive nephropathy as a cause of renal failure in chronic dialysis children].

We carried out a retrospective analysis of medical files to evaluate causes of chronic renal failure in 80 children (M--49, F--31), age 1 month to 20 years) who started renal replacement therapy in the Department of Nephrology and Dialysis of the Polish Mothers Memorial Hospital in the years 1990-2007. In 28 children (35%) reflux and obstructive nephropathy was a cause of renal failure. In 5 children the disease was secondary to the neurogenic bladder.

[Assessment of the peripheral circulation in children with nephrotic syndrome treated with cyclosporin A].

Cyclosporin A (CsA) is an immunosuppressive agent used in children for the treatment of steroid-dependent idiopathic nephrotic syndrome (INS). Despite its benefitial effect on a course of the disease CsA may exert nephrotoxic effects because of its vasoconstrictive properties. CsA-dependent disorders of the peripheral flow (Raynaud phenomenon--RP) have been recently described.

[The spectrum of congenital malformations of the urinary tract in fetuses and newborns in autopsies in 1989-2002].

The retrospective analysis of own autopsy findings of 831 fetuses and newborns with different forms of congenital malformations were carried out. In 172 cases (20.7%) urinary tract abnormalities were revealed.

Raynaud's phenomenon and endothelial dysfunction in end-stage renal disease patients treated with hemodialysis.

Background/aims: Steal syndrome is a well-known complication of arteriovenous shunt placement. Increased frequency of Raynaud's phenomenon (RP) especially concerning shunt limb is reported among hemodialysis (HD) patients. The aim of the study was to assess the relation of impairment of peripheral circulation diagnosed with cold stress test (CST) and thermography to the AV shunt location and markers of endothelial dysfunction in HD patients.

[Assessment of children at the beginning of renal replacement therapy in Lodz 1990-2000].

The time of patients' referral to dialysis predicts the clinical outcome of the therapy and significantly influences the mortality rate. The aim of the study was to assess the clinical and nutritional status and selected biochemical parameters (serum creatinine, urea, bicarbonate, calcium, albumin concentration) at the beginning of renal replacement therapy. We analysed medical history of 46 children (24 boys; 22 girls) aged 1 month-18 years (mean age 13.

[Analysis of renal replacement therapy in patients with renal failure].

The article presents the 10-years experience of renal replacement therapy in a single centre. A total of 158 patients were treated in this period. 77 patients (47 F, 30 M, mean age 18.

[Pneumoperitoneum and peritonitis in a child treated by continuous ambulatory peritoneal dialysis].

Pneumoperitoneum is a rare complication of peritoneal dialysis, which in most cases occurs soon after the implantation of the peritoneal catheter and does not need any specific treatment. In contrast, pneumoperitoneum due to visceral perforation represents a serious clinical problem and usually needs an urgent surgical intervention. We present a case of a 10-year old girl treated by peritoneal dialysis for 7 months who was admitted to hospital with symptoms of peritonitis and pneumoperitoneum.

[Dialysis-related complications in peritoneal dialysis patients].

The hospital records of 56 patients (25M, 31F) with acute or chronic renal failure treated by peritoneal dialysis were retrospectively reviewed. Mean dialysis time was 13 +/- 15 days in acute renal failure and 32 +/- 23 months in chronic renal failure. The incidence of infectious (exit site infections and peritonitis) and non-infectious dialysis-related complication was assessed.
