ABSTRACT
Background: New-onset refractory status epilepticus (NORSE) refers to patients without a previous history of seizures who have refractory status epilepticus for at least 72 hours without an identified aetiology. Despite the severe neurological sequelae of NORSE, little is known about this condition in paediatric patients. Objective: To describe the profile of paediatric patients with NORSE, the profile of seizures, possible causes attributed to this condition, treatments offered to patients and the outcomes at discharge from the paediatric intensive care unit (PICU). Methods: This retrospective, multicentre, descriptive study (case series) was conducted in the PICUs of three tertiary hospitals. We reviewed the medical records of all patients aged 0-16 years admitted to the participating PICUs between December 2013 and December 2017 with refractory status epilepticus, without a previous history of seizures or neurological disease. Results: Fifteen patients (2.4%) had NORSE. The median age of patients was 62.3 (IQR 26.2-75.4) months. All patients experienced prodromes before progressing to refractory status epilepticus. Twelve patients (80%) had fever up to 24 hours before seizures. NORSE was classified as cryptogenic in 66% of patients. Twelve patients were treated with complementary therapies, in addition to anticonvulsants. There was no standardisation in the treatment of patients. The overall mortality rate was 20%. Conclusions: NORSE is associated with high morbidity and mortality, without an identified aetiology in most cases and with a wide range of proposed therapies.
ABSTRACT
BACKGROUND & AIMS: There is a high prevalence of children with complex chronic conditions (CCCs) in pediatric intensive care units (PICUs). However, information on the nutritional status (NS) of this specific population is limited. This study aimed to evaluate the NS of critically ill pediatric patients with CCCs and to relate it to clinical outcomes. METHODS: A retrospective cohort study of children admitted to a PICU over a 4-year period. We classified NS according to body mass index-for-age (BMI/A) and height-for-age (H/A) z-scores, using the World Health Organization (WHO) growth curves as a reference. We recorded the presence of CCC according to the definition proposed by Feudtner et al. Severity on admission was measured using the Pediatric Index of Mortality 2 (PIM2). We assessed the following outcomes: mortality, multiple organ dysfunction syndrome during PICU stay, and PICU length of stay (LOS). RESULTS: We included 1753 children in the study. Presence of CCC accounted for 49.8% (873) of the sample. Among children with CCCs, 61.7% (539) had appropriate weight, 19.8% (173) were underweight, and 18.4% (161) were overweight. H/A was considered inadequate in 32.2% (281) of patients with CCCs, a higher rate than in those without CCCs (25.3%; 132) (p < 0.001). Regarding outcomes, underweight children had more organ dysfunctions and prolonged LOS. The association only remained for prolonged LOS when adjusting for confounders. Although underweight children had a higher PIM2-predicted risk of mortality, there was no significant difference in actual mortality between the three NS groups (p = 0.200). CONCLUSIONS: The rates of nutritional inadequacies in patients with CCCs were high. Underweight was independently associated with prolonged LOS in children with CCC.
