No organism was isolated from the hemoculture.Micrococcus spp. was isolated from the effluent culture, unfortunately, no specie identification and strain sensitivity for Micrococcus spp. was available by the microbiology laboratory. We were aware that vancomycin was recommended for treating this organism in previous literatures, however, regarding the favourable response of the current treatment, we decide to continue with cefazolin. The serialeffluent cleared up after 48 hours of treatment and CBC also returned to normal. No organism was isolated from follow-up effluent cultures on day 3, 7, and 15 of the treatment. Conclusion: Although Micrococcus infection is uncommon, it may potentially be a pathogen in immunocompromised

GS-1101 order hosts Ferrostatin-1 research buy and patients on peritoneal dialysis. More data concerning this organism and further study on the strain sensitivity to antimicrobial agents may be beneficial. SRISUWAN KONGGRAPUN Phramongkutklao Hospital Background: Appropriate dry weight during hemodialysis (HD) is critical for optimizing patient outcomes through prevention of chronic volume overload, hypertension and cardiomyopathy. In children, dry weights change frequently because of their growth and nutritional status. Therefore, accurate

assessment of dry weight is challenging. In most cases, dry weight is an estimate determined by physician which needs the postdialysis weight down to the point where patient does not show any signs of hypotension and volume overload. The bioelectrical impedance analysis (BIA) may be used as an alternative method to evaluate the dry weight. Methods: Dry weights from physician’s assessment

were compared with BIA method (Maltron Bioscan). The correlation between the difference of both methods and intradialytic symptoms such as fatique, not being well, thirst, cramp, headache, abdominal pain, post hemodialysis total body water (TBW), extra cellular water (ECW) and post hemodialysis blood pressure were evaluated. Results: There were 3 boys and 3 girls however with the mean age of 13.6 years (11–18). The mean dry weight in the physician’s assessment method was 35.78 ± 13 kg in comparison to the BIA method (34.55 ± 13 kg), and the mean difference was 1.23 ± 1.1 kg, p 0.042). The difference of both dry weights tend to correlated with intradialytic symptoms (r 0.267, p 0.609), post HD TBW ≥ 60% (r 0.674, p 0.142) and post HD systolic hypertension (r 0.306 p 0.555). However, there are no statistically significant except post HD ECW ≥ 40% (r 0.867, p 0.025). Conclusion: The study suggested that achieving dry weight with BIA may reduce the risk of chronic volume overload in children who on chronic hemodialysis. The routine using a BIA for dry weight assessment in children may be used because it is a simple method and does not depend on examiner’s capability, and may yield improved the better outcome. Further studies in chronic hemodialysis children are recommended to consider BIA method as the gold standard.
