For each patient, learn more demographic and anthropometric data, laboratory data, electrocardiographic findings, ultrasound results, etiology of AKI and short-term outcomes were recorded. Results: The male to

female ratio was 1.57 to 1. Mean age was 5.28 ± 6.3 (SD) years and the median was 1.8 years. The more frequent age group was children less than 2 years. The mortality rate was 22.2% (40 patients). The mortality was not correlated with age (p= 0.74). Renal replacement therapy was recommended for 62 patients (34.4%). Mean of the first and last glomerular filtration rate (GFR) were 18.33 ± 1.12 ml/min/1.73 m2 and 52.53 ± 2.98 ml/min/1.73 m2, respectively. The most common urinary sediment finding in approximately 70% of the patients was either renal epithelial cell or renal cell cast. Increased kidney echogenicity was the most common ultrasound finding (48%). Using ANOVA regression analysis, the etiology of disease was the only predictor of mortality (p = 0.0001). Conclusion: Conclusions: We concluded that the mortality is still high in AKI. Furthermore, the poor outcome (defined as low

GFR) are higher among patients with low levels of first GFR and higher RIFLE score.

The most common organisms responsible for PD-related peritonitis are gram-positive

bacteria such as Staphylococcus spp.and Streptococcus spp., gram-negative bacteria such as E. coli, Klebsiella spp. and Pseudomonas spp., and fungus. Micrococcus spp. is rarely found as a pathogen in a healthy individual. It is generally thought to be Amisulpride a commensal organism. However, several reports showed that Micrococcus could be an opportunistic pathogen, particularly in immunocompromised hosts, with one published report on Micrococcus PD peritonitis. Case report: A 17-year-old Thai boy with end-stage renal disease secondary to Immunoglobulin A nephropathy, who has been on chronic ambulatory peritoneal dialysis (CAPD), presented with a fever, abdominal pain and cloudy effluent. A complete blood count (CBC) showed leukocytosis with neutrophil predomination. The effluent cell count revealed white blood cells 530 cells/cu.mm with 70% polymorphonuclear cells. The effluent gram-stain revealed numerous polymorphonuclear white blood cells although no organisms were noted. A PD-related peritonitis was diagnosed, so, the patient was empirically treated with intraperitonealcefazolin and ceftazidime.
