ABR differences before and after dialyses.

The aim of the study was the objective evaluation of the hearing organ in children. Seven children aged 6-17 with end stage renal failure treated by haemodialysis were examined. Four- to five-hour dialyses were performed 2-3 times a week. Pure-tone audiometry was normal in five children. The reactions of brain stem responses (latency and interpeak latency) were analysed before and after haemodialyses. We conclude that the ABR differences were connected with biochemical parameters of uraemia. The present study is a preliminary one and will be continued in the future.

[Health status and physical development of children delivered by mothers who suffered from nephrotic syndrome in their infancy]. / Ocena stanu zdrowia i rozwoju fizycznego dzieci matek, które w dziecinstwie przebyly zespól nerczycowy.

Numerous complications of nephrotic syndrome due to either the illness itself or repeated courses of high-dose corticosteroids have been well recognised for several score years. However, investigations concerning children of ex-patients are lacking. The purpose of this study was to assess physical development and health state in the group of children whose mothers had suffered from the idiopathic nephrotic syndrome during their childhood. 34 such children were studied. Thorough medical history was taken from children and their mothers and available medical documents data were obtained. Physical examination was performed and centile position of weight, height and their proportion was stated. The authors found that stillborn foetus, premature or low birth weight newborn incidence is much higher than in general population and the percentage of overweight and obesity is higher in the studied group than in general population. To confirm these findings further investigations with greater number of patients are necessary.

[Anatomic and functional disorders of the urinary tract in children with urinary tract infections]. / Zaburzenia anatomiczne i czynnosciowe dróg moczowych u dzieci z zakazeniem ukladu moczowego.

The study is based on clinical analysis of 207 case recordings of children with urinary tract infection (UTI) hospitalized in The Department of Pediatric Nephrology, University Hospital, Lublin in 1995-1999. The study comprised children aged 1-18 years, average 8.8 +/- 0.4 (77.8% girls). Recurrent UTI was observed in 76.8% of children. Acute UTI was diagnosed in 20.8% of children. In 2.4% of children UTI was detected during hospitalization because of other diseases. In all children urinary X-ray examination was performed. Anatomical abnormalities were detected in 38% of children. Vesico-ureteral reflux was diagnosed in 61 children (29.5%). In 16/25 (64%) of children with vesico-ureteral reflux renal scarring was detected by radionuclide examination. In some children urodynamic examination was performed and in all of them functional abnormalities were detected.
