RESUMEN
INTRODUCTION: Therapeutic plasma exchange (TPE) is used in a wide spectrum of diseases in critically ill pediatric patients. We aim to review the indications, complications, safety, and outcomes of critically ill children who received TPE. METHODS: All of the TPE procedures performed in a pediatric intensive care unit providing tertiary care during 19 years (January 2013-January 2023) were evaluated retrospectively. A total of 154 patients underwent 486 TPE sessions. RESULTS: Median age was 6 years (2-12.5) and 35 children had a body weight of <10 kg (22.7%). Number of organ failure was 4 (2-6). Liver diseases were the most common indication for TPE (31.2%) followed by sepsis with multiorgan dysfunction syndrome (27.3%). Overall survival rate was 72.7%. The highest mortality was observed in hemophagocytic lymphohistiocytosis group. Non-survivors had significantly higher number of organ failure (p < 0.001), higher PRISM score (p < 0.001), and higher PELOD score on admission (p < 0.001). Adverse events were observed in 68 (13.9%) sessions. Hypotension (7.8%) and hypocalcemia (5.1%) were the most frequent adverse events. CONCLUSION: TPE is safe for critically ill pediatric patients with experienced staff. Survival rate may vary depending on the underlying disease. Survival decreases with the increase in the number of failed organs.
RESUMEN
OBJECTIVE: In this study, we aimed to evaluate the effects of decompressive craniectomy (DC) on the brain death (BD) determination process in the pediatric intensive care unit (PICU). MATERIALS AND METHODS: All children who were diagnosed with BD in the PICU between 2009 and 2020 were included in this study. Patient demographics, causative mechanisms, BD examinations, and ancillary tests used were recorded. The time intervals (from PICU admission to first BD examination, from first BD examination to BD diagnosis) and number of BD examinations were compared between patients with and without DC. RESULTS: During the study period, 70 pediatric cases were diagnosed with BD among 513 total deaths (13.6%). Their median age was 54.5 months [interquartile range (IQR): 24-140]. Transcranial Doppler ultrasound (TCD) was performed in 66 patients (94.3%). The most common combination of ancillary tests was the apnea test and TCD combination, which was performed in 56 patients (80%). Thirty-four children (48.6%) experienced immediate surgery for DC. Patients with DC had a higher median number of BD examinations than patients without DC [3 (IQR: 2-3) vs. 2 (IQR: 1-2), P < .001]. The patients with DC had a longer time interval between the first examination and declaration of BD than patients without DC [45.5 hours (IQR: 21.7-91.7) versus 15 hours (IQR: 2-31.2), P < .006]. CONCLUSION: Decompressive craniectomy may complicate BD determination and cause challenges for brain death diagnosis based on cerebral flow imaging techniques. The lack of specific recommendations for this patient group in the guidelines causes a delayed diagnosis of BD.

RESUMEN
AIMS: As the COVID-19 pandemic continues, multisystem inflammatory syndrome in children (MIS-C) maintains its importance in the differential diagnosis of common febrile diseases. MIS-C should be promptly diagnosed because corticosteroid and/or intravenous immunoglobulin treatment can prevent severe clinical outcomes. In this study, we aimed to evaluate clinical presentation, diagnostic parameters and management of MIS-C and compare its clinical features to those of common febrile disease. METHODS: This study was conducted at a tertiary-level university hospital between December 2020 and October 2022. One hundred and six children who were initially considered to have MIS-C disease were included in the study. During the follow-up period in the hospital, when the clinical and laboratory findings were re-evaluated, 38 out of 106 children were diagnosed differently. The clinical and laboratory findings of 68 children followed up with the diagnosis of MIS-C and 38 children who were initially misdiagnosed as MIS-C but with different final diagnoses were retrospectively compared. RESULTS: We identified 68 patients with MIS-C and 38 patients misdiagnosed as MIS-C during the study period. Infectious causes (71%), predominantly bacterial origin, were the most frequently confused conditions with MIS-C. Patients with MIS-C were older and had a more severe clinical course with high rates of respiratory distress, shock, and paediatric intensive care unit admission. While rash and conjunctivitis were more common among patients with MIS-C, cough, abdominal pain and diarrhoea were observed more frequently in patients misdiagnosed as MIS-C. Lower absolute lymphocyte counts, platelet counts and higher C-reactive protein and fibrinogen levels, pathological findings on echocardiography were the distinctive laboratory parameters for MIS-C. Multivariate analysis showed that older age, presence of conjunctivitis, high level of serum CRP and lower platelets were the most discriminative predictors for the diagnosis of MIS-C. CONCLUSION: There are still no specific findings to diagnose MIS-C, which therefore can be confused with different clinical conditions. Further data are needed to assist the clinician in the differential diagnosis of MIS-C and the diagnostic criteria should be updated over time.
