[The effect of treatment methods on frequency of relapse in nephrotic syndrome in children]. / Wplyw metody leczenia na czestosc nawrotów zespolu nerczycowego u dzieci.

The purpose of the work was to evaluate the influence of the treatment method in nephrotic syndrome on remission time and frequency of sickness relapse. Assessments were made in 26 children aged 1-17 years hospitalised in the Pediatric and Nephrology Department of the Military School of Medicine from 1993-1999. All children were steroid-sensitive, but only one patient didn't have relapse during the 3-years of observation. Because the most of children had oedema syndrome (92.3%) the treatment was started with intravenous hydrocortisone and continued with oral prednisone according to International Study of Kidney Disease in Children (ISKDC) criteria. 10 children with steroid-dependent syndrome were treated with intravenous methylprednisolone. Levamisole was given to 7 patients with concomitant respiratory infection. 7 other children were qualified for chlorambucil treatment. Choice of the treatment method in steroid-dependent and frequently relapsing nephrotic syndrome should be concordant with specificity of the particular patient's disease.

[Analysis of erythrocyturia causes in children]. / Analiza przyczyn krwinkomoczu u dzieci.

The aim of this study was to assess, on the basing on clinical observation, the causes of erythrocyturia in children. The study include 438 children (214 girls and 224 boys) between 6 month and 17-teen years old with erythrocyturia, treated in Pediatric Nephrology Department from September 1992 till October 1999. The most common was the group of children with urolithiasis--162 (36.99%) and preurolithiasis state--126 (28.77%). In 153 cases urolithiasis was the only reason of erythrocyturia and in 9 children near urolithiasis the other reason (vesicouretheral reflux, urinary tract infection, glomerulitis, polycystic kidney) has been found. In 103 children the preulithiasis state was the only cause of erythrocyturia, in 23 children it was coexisted with others (vesicouretheral reflux, urinary tract infection, glomerulitis). As the more rare common causes were established vesicouretheral reflux, urinary tract infection, glomerulonephritis, in 36 children (8%) we did not find the reason of erythrocyturia. Variety of the reasons makes differential diagnostics of erythrocyturia complicated and needs experience and specialistic diagnostic investigation.
