Background: Febrile neutropenia is defined as a fever with a temperature more than or equal to 38.3°C in two measurements within 24 hours and accompanied by severe neutropenia (≤500/μL). Gram-positive bacteria have been the most common cause of febrile neutropenia in children for the previous two decades. However, the contradiction in some studies reported that gram-negative bacteria were the main pathogens causing infection. Because there are differences and shifts in the bacterial spectrum, information on the bacterial pattern and antibiotic susceptibility is critical to reaching the optimal management of febrile neutropenia patients. Methods: This observational, descriptive study was conducted in Sanglah Hospital, Bali, Indonesia, involving pediatric patients (<18 years old) with febrile neutropenia. Data on antibiotic susceptibility and microbial patterns were collected retrospectively from the blood culture registry taken from febrile neutropenia patients from October 2017 to August 2020. Collected data were analyzed using the SPSS program for Windows, version 21.0. Univariate analysis was conducted, and data with a categorical scale were reported in frequency distribution and percentage, then displayed in a table and graph. Result: A total of 180 episodes of febrile neutropenia were collected from 89 patients. Among 180 blood cultures, there were found 44 (24.44%) blood cultures with positive results. A higher proportion of gram-negative organisms (33; 75%) is found compared to gram-positive organisms (11; 25%). The susceptibility rates were 100% for Azithromycin, Amoxicillin Clavulanate, Cefoperazone Sulbactam, Meropenem, Linezolid, and Doxycycline, while Cefepime, the previous empirical antibiotic, was susceptible at 79.31% isolates. Conclusion: Gram-negative bacteria were the most frequent cause of infection among febrile neutropenic patients. Although the research evidence is still weak due to the small sample size, Cefoperazone Sulbactam could be a better option to replace Cefepime as an empirical antibiotic due to its significantly higher susceptibility.

Background: Immune thrombocytopenic purpura (ITP) is the most common cause of thrombocytopenia in children that characterized by isolated thrombocytopenia that vary in bleeding manifestations. The onset of disease is sudden and a self-limiting condition that requires treatment when clinically significant bleed occurs. A treatment goal is to increase platelet level above safety level and reduce the risk of severe bleeding. This study aims to evaluate the platelets level increment after three days treatment among children with acute ITP.Methods: An analytic retrospective cross-sectional study was conducted in Haematology-Oncology Paediatric Division Sanglah General Hospital, Bali, Indonesia from October 2008 to October 2018 in ITP patients. Diagnosis of ITP was evaluated based on the clinical manifestation and laboratory finding. Oral corticosteroid medication with dosage 2 mg/kg/day or 4 mg/kg/day with or without platelets transfusion were enrolled in this study from medical records. Data were analyzed using SPSS version 20 for Windows.Results: There were 93 children met the inclusion criteria and included in this study. A median platelets level at admission was 6.81(1-86.8) x 109/L. Majority symptoms of children with ITP in our tertiary care centre presented with mild to moderate clinical bleeding symptoms. Only 5.6% children with platelets level below 10x109/L had intracranial bleeding. Median platelets level was 31(2.47-382) x 109/l and there was a significant platelets level increment after three days of therapy (P<0.05).Conclusion: The platelets level increment significantly in children with acute ITP after three days of therapy.
