BACKGROUND AND OBJECTIVES Extensive literature supports using dexamethasone (DEX) in children presenting to the emergency department (ED) with mild-to-moderate asthma exacerbations; however, only limited studies have assessed this in hospitalized children. In this study, we evaluate the outcomes of DEX versus prednisone/prednisolone (PRED) use in children hospitalized for mild-to-moderate asthma exacerbations. METHODS This multisite retrospective cohort study included children between 3 and 21 years of age hospitalized to a tertiary care children’s hospital system between January 1, 2013, and December 31, 2017, with a primary discharge diagnosis of acute asthma exacerbation or status asthmaticus. Primary study outcome was mean hospital length of stay (LOS). Secondary outcomes included PICU transfers during initial hospitalization and ED revisits and hospital readmissions within 10 days after discharge. Generalized linear models were used to model logged LOS as a function of steroid and demographic and clinical covariates. The analysis was stratified by initial steroid timing. RESULTS Of the 1410 children included, 981 received only DEX and 429 received only PRED. For children who started oral steroids after hospital arrival, DEX cohort had a significantly shorter adjusted mean hospital LOS (DEX 24.43 hours versus PRED 29.38 hours; P = .03). For children who started oral steroids before hospital arrival, LOS did not significantly differ (DEX 26.72 hours versus PRED 25.20 hours; P = .45). Rates of PICU transfers, ED revisits, and hospital readmissions were uncommon events. CONCLUSION Children hospitalized with mild-to-moderate asthma exacerbations have significantly shorter hospital LOS when starting DEX rather than PRED on admission.

BACKGROUND: Previous studies of reference values for cerebrospinal fluid (CSF) profiles have been limited by small sample size and few exclusion criteria.OBJECTIVE: To determine age-specific normative CSF white blood cell count (WBC), glucose, and protein values in infants #90 days old.METHODS: Performed a retrospective cross-sectional study of infants #90 days old who had a diagnostic lumbar puncture between 2008 and 2016. Infants with bacterial meningitis, bacteremia, UTI, positive CSF herpes simplex virus polymerase chain reaction (PCR) result, traumatic lumbar puncture, ventriculoperitoneal shunt, prematurity, recent seizure, previous antibiotic use, and history of a complex chronic condition were excluded for calculations to determine normative values. Data on demographics and CSF values (WBC with differential, protein, glucose, enterovirus PCR) were collected. CSF values were compared by age and by enterovirus PCR results using Kruskal-Wallis and Wilcoxon rank tests. RESULTS:A total of 1029 out of 2000 patients were included and divided into 3 age groups: 0 to 28 days, 29 to 60 days, 61 to 90 days. CSF WBC values were significantly greater for 0-to 28-day old infants (median: 3, 95th percentile: 14) than for 29-to 60-day and 61-to 90-day old infants (median: 2 and 2; 95th percentile: 7 and 11, respectively) (P < .001). With each month of life, the median CSF protein significantly decreased and glucose significantly increased. In the CSF WBC differential, monocytes were found to be prevalent. CONCLUSION:We determined age-specific normative components for CSF profile values for infants 0 to 90 days.
