Probable air embolism during Tenckhoff catheter placement.

Acute cardiovascular collapse occurred in a 15-year-old girl during peritoneoscopic placement of a Tenckhoff catheter. The case demonstrates a potential complication of this procedure: air embolism. A review of the management and prevention of this problem is provided.

Serial hippuran renograms to detect the late onset of renal allograft rejection in pediatric transplant recipients.

Serial hippuran renograms were performed in pediatric allograft recipients in an effort to detect the onset of rejection following the initial 3 month post transplant period. The plots of the normalized effective renal plasma flows (NERPF) were compared with reciprocal of the serum creatinines. A strong correlation was noted between both values. NERPF could be predicted from the serum creatinine utilizing a logarithmic equation. However, there was no detectable difference between the onset of changes in the slopes of either variable. Therefore, serial hippuran renograms were no better than monitoring serum creatinine in detecting allograft dysfunction when performed at the frequency of the study.

Cognitive functioning in children with end stage renal disease pre- and post-dialysis session.

Eighteen ESRD and 18 Control subjects equated for age and intellectual level were assessed pre- and post-dialysis on measures of learning, problem solving and immediate memory. No significant differences were found between ESRD and Control subjects on any of the measures. Both groups showed significant learning over trials on the Paired Associate Learning Task. No correlational associations of statistical or clinical significance were found between the cognitive measures and blood pressure, blood urea nitrogen or serum creatinine. There was no difference between pre- and post-dialysis session performance by the ESRD subjects. These findings were inconsistent with prior research showing immediate improvement in cognition post-dialysis.

Factors affecting cyclosporine-induced gingival overgrowth in pediatric renal transplant recipients.

The purpose of this research was to study the occurrence of gingival overgrowth (GO) in children after kidney transplantation and to investigate the relationship of GO to medical and dental parameters. Forty-nine kidney transplant patients taking the immunosuppressive drug cyclosporine A (CsA) were evaluated for plaque (PI), calculus (CI), gingival inflammation (GI), probing depth (PD), width of keratinized gingiva (GW), and gingival overgrowth (GO). Blood trough levels and oral dosages of CsA were obtained from medical charts on the day of examination. Most (77.5%) subjects exhibited GO, suggesting that GO is a frequent problem in children and adolescents ingesting CsA. GI, PD, and GW were found to be statistically significantly greater in subjects with GO than in those without GO. CsA dose/day was not significantly different between subjects with GO and those without GO. CsA dose/kg body weight and blood trough levels of CsA were significantly higher in subjects without GO, but the average length of time subjects without GO had been ingesting CsA was only 1.3 months, compared with an average 3.5 years for subjects with GO. The results indicate that in young subjects, duration of CsA ingestion may be the most critical factor related to eventual GO development.
