Abstract
OBJECTIVE We aimed to characterize intravenous (IV) methylprednisolone (MP) dosing regimens and clinical outcomes for children hospitalized for critical asthma (CA). METHODS A single-center, retrospective review was performed of children admitted to the pediatric intensive care unit (PICU) for CA between September 2015 and October 2019. Patients 5-to 17-year-olds, initiated on continuous nebulized albuterol, and prescribed at least one dose of IV MP were included. The primary outcome was to characterize PICU MP dosing. Cohorts were then compared by MP dosing: conservative-dose methylprednisolone (CDMP, ≤ 0.5 mg/kg/dose every 6 h) and standard-dose methylprednisolone (SDMP, > 0.5 mg/kg/dose every 6 h). Clinical efficacy endpoints were the duration of continuous nebulized albuterol and PICU length of stay (LOS). Safety endpoints included corticosteroid-related adverse events. RESULTS Of 168 children studied, 50 (29.8%) were prescribed CDMP and 118 (70.2%) SDMP. The overall mean MP dose was 31.3 ± 19.6 mg (weight-adjusted: 0.77 ± 0.32 mg/kg/dose). Compared to those prescribed SDMP, those prescribed CDMP had a shorter median duration of continuous nebulized albuterol (12.8 [IQR: 10.5-20] versus 17.3 [IQR: 11.3-29.7] hours, p = 0.019) and median PICU LOS (0.9 [IQR: 0.7-1.4] versus 1.2 [IQR: 0.9-1.8] days, p = 0.012). No corticosteroid-related adverse events were observed. In adjusted models, weight-adjusted IV MP dose was not associated with PICU LOS or duration of continuous nebulized albuterol. CONCLUSIONS Intravenous MP dosing for pediatric CA varied widely in our study sample. Prospective, controlled trials are required to validate our observations including clinical efficacy and safety endpoints.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy of a single dose of dexamethasone to 2 doses of dexamethasone in treating mild to moderate asthma exacerbations in pediatric patients. We anticipated that there would not be a difference in the rate of return visits to the emergency department (ED), urgent care, or primary care physician for continued asthma symptoms. METHODS This was a prospective, randomized, single-center, unblinded, parallel-group randomized clinical trial of patients 2 to 20 years old presenting to a pediatric ED with mild to moderate asthma exacerbations. The patients were randomized to receive 1 or 2 doses of dexamethasone (0.6 mg/kg per dose, maximum of 16 mg). Telephone follow-up interviews were performed on the sixth day after ED visit. The primary outcome measures were return visits to either primary care physician or ED for continued asthma symptoms. Secondary outcomes were days of symptoms, missed school days, and adverse effects. RESULTS Of the 318 children initially enrolled, 308 patients met the enrollment criteria. These patients were randomized into 2 groups. There were 116 patients in group 1 and 116 patients in group 2. There was no significant difference between groups regarding return visits (group 1, 12.1%; group 2, 10.3%; odds ratio [OR], 0.892 [95% confidence interval {CI}, 0.377-2.110]), days to symptom resolution (group 1, 2.4; group 2, 2.5; OR, 0.974 [95% 95% CI, 0.838-1.132]), missed school days (group 1, 47%; group 2, 51%; OR, 1.114 [95% CI, 0.613-2.023]), or vomiting (group 1, 8.6%; group 2, 3.4%; OR, 2.424 [95% CI, 0.637-9.228]). CONCLUSIONS In this single-center, unblinded randomized trial of children and adolescents with mild to moderate acute exacerbations of asthma, there was no difference in the rate of return visits for continued or worsened symptoms between patients randomized to 1 or 2 doses of dexamethasone.

Abstract
AIM Emesis of oral medications continues to be a problem in the management of acute pediatric asthma exacerbations; therefore, we set out to assess whether smaller volumes of oral dexamethasone resulted in better tolerability. METHODS Children aged 2-14 years, presenting to the emergency department with acute asthma exacerbation, were enrolled in this open, prospective randomized controlled trial. Participants received 0.3 mg/kg of dexamethasone in either its concentrated volume (10 mg/mL) or mixed with Ora Sweet (1 mg/mL). Tolerability was measured by vomiting within 45 minutes of receiving dexamethasone, with stratification, a priori, for prior vomiting. RESULTS 430 participants were enrolled. 23/213 (11%) in the 10 mg/mL group vomited dexamethasone compared to 16/217 (7%) in the 1 mg/mL group (P = .29). 11/179 (6%) in the 10 mg/mL group vomited compared to 8/183 (3%) in the 1 mg/mL group (.61). For those 68 stratified with prior vomiting, 12/34 (35%) in the 10 mg/mL group vomited compared to 8/34 (24%) in the 1 mg/mL group (P = .43). None of these results were statistically different. Prior vomiting increased the risk of vomiting, regardless of the formulation given (P < .001). CONCLUSIONS Volume does not play a significant role in the tolerability of dexamethasone. Therefore, palatability should not be sacrificed for a smaller volume of dexamethasone to improve tolerability.

Abstract
Background Asthma is the most common chronic disease of childhood and a major source of childhood health burden worldwide. These burdens are particularly marked when children experience characteristic ‘symptom flare-ups’ or acute asthma exacerbations (AAEs). AAE are associated with significant health and economic impacts, including acute Emergency Department visits, occasional hospitalizations, and rarely, death. To treat children with AAE, several medications have been studied and used. Methods We conducted a narrative review of the literature with the primary objective of understanding the evidence of their efficacy. We present this efficacy evidence in the context of a general stepwise management pathway for paediatric AAEs. This framework is developed from the combined recommendations of eight established (inter)national paediatric guidelines. Discussion Management of paediatric AAE centres around four major care goals: (1) immediate and objective assessment of AAE severity; (2) prompt and effective medical interventions to decrease respiratory distress and improve oxygenation; (3) appropriate disposition of patient; and (4) safe discharge plans. Several medications are currently recommended with varying efficacies, including heliox, systemic corticosteroids, first-line bronchodilators (salbutamol/albuterol), adjunctive bronchodilators (ipratropium bromide, magnesium sulfate) and second-line bronchodilators (aminophylline, i.v. salbutamol, i.v. terbutaline, epinephrine, ketamine). Care of children with AAE is further enhanced using clinical severity scoring, pathway-driven care and after-event discharge planning. Conclusions AAEs in children are primarily managed by medications supported by a growing body of literature. Continued efforts to study the efficacy of second-line bronchodilators, integrate AAE management with long-term asthma control and provide fair/equitable care are required.

Abstract
A retrospective chart review was done to evaluate the efficacy of a course of dexamethasone for pediatric patients hospitalized with a mild to moderate acute asthma exacerbation compared with a prednisone-based regimen. Patients were identified based on International Classification of Diseases (ICD-9 and ICD-10) discharge diagnosis codes for asthma and cross-referenced with pharmacy dispense reports during the study period of June 2011 to January 2016. Baseline characteristics were similar among the 2 groups. The median length of hospital stay in the dexamethasone and prednisolone groups were 1.31 and 1.75 days, respectively, with a hazard ratio of 2.5 (95% confidence interval - 2.1-3.1), P < .001. After accounting for significant confounding variables, the difference in length of stay remained significantly longer in the prednisolone group with a hazard ratio of 1.8 (95% confidence interval = 1.4-2.3), P < .001. A course of dexamethasone is associated with a significantly shorter length of stay for mild to moderate asthma exacerbations compared with a prednisone-based regimen.

Abstract
Systemic/oral corticosteroids (OCS) have been used for decades in the management of acute asthma exacerbations and chronically in patients with uncontrolled severe asthma. However, while OCS are effective at treating acute exacerbations, there is only empirical evidence regarding the efficacy of OCS at reducing the rate of exacerbations. Evidence, although scarce, is suggestive of high exacerbation rates in severe asthma patients even when receiving maintenance treatment with OCS. In addition, use of OCS is associated with undesirable effects. Despite all this, physicians have continued to use OCS for managing severe asthma and acute exacerbation due to the lack of availability of effective alternatives. Fortunately, in the last decade several biologics have been proven safe and effective for patients with uncontrolled severe asthma. This has led to the Global Initiative for Asthma (GINA) recommending the use of biologics, instead of maintenance OCS, in patients with severe asthma (GINA Step 5). These include one biologic targeting immunoglobulin E (IgE) (omalizumab), and different biologics targeting interleukin-5 (IL-5), the IL-5 receptor (IL-5R) or IL-4 receptor α-unit (IL-4R α), including mepolizumab (subcutaneous), reslizumab (intravenous), benralizumab (subcutaneous) and dupilumab (subcutaneous). Omalizumab for the treatment of severe allergic asthma reduces exacerbations, irrespective of blood eosinophil levels. Anti-IL-5/IL-5R biologics are indicated in patients with severe eosinophilic asthma and repetitive exacerbations, irrespective of the presence or absence of allergy. Recently, an anti-IL4Rα biologic has been approved by the FDA for eosinophilic phenotype or oral corticosteroid-dependent asthma. Finally, physicians should consider using biologics as an alternative to chronic OCS therapy.

Abstract
Dexamethasone has been proposed as an alternative in the treatment of acute asthma exacerbation in children. It allows shortening the duration of treatment, reducing costs and adverse effects. However, it is not clear whether its efficacy is similar to the traditional steroid regimen. To answer this question, we searched in Epistemonikos database, which is maintained by screening multiple information sources. We identified six systematic reviews including 10 randomized trials. We extracted data, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded dexamethasone has probably fewer adverse effects than others corticosteroids, and might be equally effective in reducing hospitalizations and revisits.

Abstract
Wheezing viral respiratory illnesses are the most common initial presentation of childhood asthma. Once asthma is established, viral infections, most notably rhinovirus (RV), are the most frequent trigger of severe asthma exacerbations. RV-C appears to be a particularly pathogenic virus in children with asthma. Evidence has recently emerged to suggest that bacterial pathogens in the lower airway may contribute to the expression of asthma. Ongoing studies are critical to our understanding of the role of the airway microbiome in asthma inception and exacerbation. Synergistic interactions between underlying allergy and virus infections play an important mechanistic role in asthma inception and exacerbation, and are an important therapeutic target. Novel therapies are needed to prevent and treat virus-induced wheezing and asthma exacerbations.

Abstract
OBJECTIVE Poor adherence to the National Institute of Health (NIH) Asthma Guidelines may result in unnecessary admissions for children presenting to the emergency department (ED) with exacerbations. We determine the effect of implementing an evidence-based ED clinical pathway on corticosteroid and bronchodilator administration and imaging utilization, and the subsequent effect on hospital admissions in a US ED. METHODS A prospective, interventional study of pediatric (≤21 years) visits to an academic ED between 2011 and 2013 with moderate-severe asthma exacerbations has been conducted. A multidisciplinary team designed a one-page clinical pathway based on the NIH Guidelines. Nurses, respiratory therapists and physicians attended educational sessions prior to the pathway implementation. By adjusting for demographics, acuity and ED volume, we compared timing and appropriateness of corticosteroid and bronchodilator administration, and chest radiograph (CXR) utilization with historical controls from 2006 to 2011. Subsequent hospital admission rates were also compared. RESULTS A total of 379 post-intervention visits were compared with 870 controls. Corticosteroids were more likely to be administered during post-intervention visits (96% vs. 78%, adjusted OR 6.35; 95% CI 3.17-12.73). Post-intervention, median time to corticosteroid administration was 45 min faster (RR 0.74; 95% CI 0.67-0.81) and more patients received corticosteroids within 1 h of arrival (45% vs. 18%, OR 3.5; 95% CI 2.50-4.90). More patients received > 1 bronchodilator dose within 1 h (36% vs. 24%, OR 1.65; 95% CI 1.23-2.21) and fewer received CXRs (27% vs. 42%, OR 0.7; 95% CI 0.52-0.94). There were fewer admissions post-intervention (13% vs. 21%, OR 0.53; 95% CI 0.37-0.76). CONCLUSION A clinical pathway is associated with improved adherence to NIH Guidelines and, subsequently, fewer hospital admissions for pediatric ED patients with asthma exacerbations.

Abstract
Uncomplicated upper respiratory viral infections are the most common cause of days lost from work and school and exert a major economic burden. In susceptible individuals, however, common respiratory viruses, particularly human rhinoviruses, also can have a major impact on diseases that involve the lower airways, including asthma, chronic obstructive pulmonary diseases (COPD) and cystic fibrosis (CF). Respiratory virus-induced wheezing illnesses in early life are a significant risk factor for the subsequent development of asthma, and virus infections may also play a role in the development and progression of airway remodeling in asthma. It is clear that upper respiratory tract virus infections can spread to the lower airway and trigger acute attacks of asthma, COPD or CF. These exacerbations can be life-threatening, and exert an enormous burden on health care systems. In recent years we have gained new insights into the mechanisms by which respiratory viruses may induce acute exacerbations of lower airway diseases, as well as into host defense pathways that may regulate the outcomes to viral infections. In the current article we review the role of viruses in lower airway diseases, including our current understanding on pathways by which they may cause remodeling and trigger acute exacerbations. We also review the efficacy of current and emerging therapies used to treat these lower airway diseases on the outcomes due to viral infection, and discuss alternative therapeutic approaches for the management of virus-induced airway inflammation.

Abstract
BACKGROUND Inhaled anticholinergics given in addition to β2-agonists are effective in reducing hospital admissions in children presenting to the emergency department with a moderate to severe asthma exacerbation. It seems logical to assume a similar beneficial effect in children hospitalised for an acute asthma exacerbation. OBJECTIVES To assess the efficacy and safety of anticholinergics added to β2-agonists as inhaled or nebulised therapy in children hospitalised for an acute asthma exacerbation. To investigate the characteristics of patients or therapy, if any, that would influence the magnitude of response attributable to the addition of anticholinergics. SEARCH METHODS We identified trials from the Cochrane Airways Group Specialised Register of trials (CAGR), which is derived through systematic searches of bibliographic databases including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, AMED and PsycINFO and through handsearching of respiratory journals and meeting abstracts. The search is current to November 2013. SELECTION CRITERIA Randomised trials comparing the combination of inhaled or nebulised anticholinergics and short-acting β2-agonists versus short-acting β2-agonists alone in children one to 18 years of age hospitalised for an acute asthma exacerbation were eligible. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the methodological quality of trials and extracted data; disagreement was resolved by consensus or with the input of a third review author, when needed. Primary outcomes were duration of hospital stay and serious adverse events. Secondary outcomes included admission and duration of stay in the intensive care unit (ICU), ventilation assistance, time to short-acting β2-agonists spaced at four hours or longer, supplemental asthma therapy, duration of supplemental oxygen, change from baseline in asthma severity, relapse after discharge, adverse health effects and withdrawals. MAIN RESULTS Seven randomised trials were included, four of which reported usable data on 472 children with asthma one to 18 years of age who were admitted to paediatric wards. No trials included patients admitted to the ICU. The anticholinergic used, ipratropium bromide 250 μg, was given every one to eight hours over a period from four hours to the entire length of the hospital stay. Two of four trials (50%) contributing data were deemed of high methodological quality. The addition of anticholinergics to β2-agonists showed no evidence of effect on the duration of hospital admission (mean difference (MD) -0.28 hours, 95% confidence interval (CI) -5.07 to 4.52, 3 studies, 327 participants, moderate quality evidence) and no serious or non-serious adverse events were reported in any included trials. As a result of the similarity of trials, we could not explore the influence of age, admission site, intensity of anticholinergic treatment and co-interventions on primary outcomes. No statistically significant group difference was noted in other secondary outcomes, including the need for supplemental asthma therapy, time to short-acting β2-agonists spaced at four hours or longer, asthma clinical scores, lung function and overall withdrawals for any reason. AUTHORS' CONCLUSIONS In children hospitalised for an acute asthma exacerbation, no evidence of benefit for length of hospital stay and other markers of response to therapy was noted when nebulised anticholinergics were added to short-acting β2-agonists. No adverse health effects were reported, yet the small number of trials combined with inadequate reporting prevent firm reassurance regarding the safety of anticholinergics. In the absence of trials conducted in ICUs, no conclusion can be drawn regarding children with impending respiratory failure. These findings support current national and international recommendations indicating that healthcare practitioners should refrain from using anticholinergics in children hospitalised for acute asthma.

Abstract
BACKGROUND A short course of systemic corticosteroids is an important therapy in the treatment of pediatric asthma exacerbations. Although a 5-day course of oral prednisone or prednisolone has become the most commonly used regimen, dexamethasone has also been used for a shorter duration (1-2 days) with potential for improvement in compliance and palatability. We reviewed the literature to determine if there is sufficient evidence that dexamethasone can be used as an effective alternative in the treatment of pediatric asthma exacerbations in the inpatient setting. METHODS A Medline search was conducted on the use of dexamethasone in the treatment of asthma exacerbations in children. The studies selected were clinical trials comparing the efficacy of dexamethasone with prednisone. Meta-analysis was performed examining physician revisitation rates and symptomatic return to baseline. RESULTS Six completed pediatric clinical trials met the inclusion criteria. All of the pediatric trials found that prednisone is not superior to dexamethasone in treating mild to moderate asthma exacerbations. Meta-analysis demonstrated homogeneity between the dexamethasone and prednisone groups when examining symptomatic return to baseline and unplanned physician revisits after the initial emergency department encounter. Some studies found potential additional benefits of dexamethasone, including improved compliance and less vomiting. CONCLUSIONS The current literature suggests that dexamethasone can be used as an effective alternative to prednisone in the treatment of mild to moderate acute asthma exacerbations in children, with the added benefits of improved compliance, palatability, and cost. However, more research is needed to examine the role of dexamethasone in hospitalized children.

Abstract
OBJECTIVE To compare the effects of inhaled corticosteroids (ICS) against systemic corticosteroids (SC) in children consulting in emergency department (ED) or equivalent for asthma exacerbation. METHODS Electronic search in MEDLINE, CENTRAL, CINAHL, and LILACS databases and other sources. Study selection criteria: children 2-18 years of age, consulting in ED or equivalent for asthma exacerbation, comparison between ICS and SC, randomized controlled trials. PRIMARY OUTCOMES hospital admission rate, unscheduled visits for asthma symptoms, need of additional course of SC. SECONDARY OUTCOMES improvement of lung function, length of stay in ED, clinical scores, and adverse effects. RESULTS Eight studies met inclusion criteria (N = 797), published between 1995 and 2006. All used prednisolone as SC and budesonide, fluticasone, dexamethasone, and flunisolide were administered as ICS. No significant difference between ICS versus SC was found in terms of hospital admission (RR: 1.02; 95% CI: 0.41-2.57), unscheduled visits for asthma symptoms (RR: 9.55; 95% CI: 0.53-170.52) nor for need of additional course of SC (RR: 1.45; 95% CI: 0.28-7.62). The change in % of predicted FEV1 at fourth hour was significantly higher for SC group, but there was no significant difference between both groups after this time. There was insufficient data to perform meta-analysis of length of stay during first consult in ED and of symptom scores. Vomiting was similar among both groups. CONCLUSIONS There is no evidence of a difference between ICS and SC in terms of hospital admission rates, unscheduled visits for asthma symptoms and need of additional course of SC in children consulting for asthma exacerbations.

Abstract
OBJECTIVE This study aimed to identify factors associated with delayed or omission of indicated steroids for children seen in the emergency department (ED) for moderate-to-severe asthma exacerbation. METHODS This was a retrospective study of pediatric (age ≤ 21 years) patients treated in a general academic ED from January 2006 to September 2011 with a primary diagnosis of asthma (International Classification of Diseases, Ninth Revision code 493.xx) and moderate-to-severe exacerbations. A moderate-to-severe exacerbation was defined as requiring 2 or more (or continuous) bronchodilators. We determined the proportion of visits in which steroids were inappropriately omitted or delayed (>1 hour from arrival). Multivariable logistic regression models were used to identify patient, physician, and system factors associated with delayed or omitted steroids. RESULTS Of 1333 pediatric asthma ED visits, 817 were for moderate-to-severe exacerbation; 645 (79%) received steroids. Patients younger than 6 years (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.19-4.24), requiring more bronchodilators (OR, 2.82; 95% CI, 2.10-3.79), initially hypoxic (OR, 2.78; 95% CI, 1.33-5.83), or tachypneic (OR, 1.52; 95% CI, 1.05-2.20) were more likely to receive steroids. Median time to steroid administration was 108 minutes (interquartile range, 65-164 minutes). Steroid administration was delayed in 502 visits (78%). Patients with hypoxia (OR, 1.91; 95% CI, 1.11-3.27) or tachypnea (OR, 1.82; 95% CI, 1.17-2.84) were more likely to receive steroids 1 hour or less of arrival, whereas children younger than 2 years (OR, 0.16; 95% CI, 0.07-0.35) and those arriving during periods of higher ED volume (OR, 0.79; 95% CI, 0.67-0.94) were less likely to receive timely steroids. CONCLUSIONS In this ED, steroids were underprescribed and frequently delayed for pediatric ED patients with moderate-to-severe asthma exacerbation. Greater ED volume and younger age are associated with delays. Interventions are needed to expedite steroid administration, improving adherence to National Institutes of Health asthma guidelines.

Do oral corticosteroids reduce the severity of acute lower respiratory tract illnesses in preschool children with recurrent wheezing? J Allergy Clin Immunol 2013; 131:1518-25.

Abstract
BACKGROUND Oral corticosteroids (OCSs) are recommended for severe wheezing episodes in children. However, limited evidence supports this intervention in preschool children with outpatient wheezing illnesses. OBJECTIVE We sought to investigate whether OCSs reduce symptom scores during acute lower respiratory tract illnesses (LRTIs) in preschool children with recurrent wheeze. METHODS We performed post hoc and replication analyses in 2 outpatient cohorts of children aged 1 to 5 years with episodic wheezing participating in clinical trials. We compared symptom scores during LRTIs that were or were not treated with OCSs, adjusting for differences in disease and episode severity covariates. We stratified episodes by severity by using a propensity model. The primary outcome was the area under the curve (AUC) of total symptom scores among the more severe episodes. RESULTS Two hundred fifteen participants from the Acute Intervention Management Strategies trial experienced 798 acute LRTIs, 112 of which were defined as severe based on propensity scores. The AUCs of total symptom scores did not differ between the episodes that were (n = 70) and were not (n = 42) treated with OCSs (P = .46) nor was there an OCS treatment effect on individual symptom scores. Similar analyses of the Maintenance Versus Intermittent Inhaled Corticosteroids in Wheezing Toddlers trial, involving 278 participants with 133 severe LRTIs, confirmed the above findings (P = .46 for AUC of total symptoms score comparison). CONCLUSION In 2 separate cohorts of preschool children with episodic wheezing, OCS treatment during clinically significant LRTIs did not reduce symptom severity during acute LRTIs, despite asthma controller medication use during most episodes. These findings need to be confirmed in a prospective randomized controlled trial.

Abstract
OBJECTIVE This study was done to understand the demographics, clinical course, and outcomes of children with status asthmaticus treated in a tertiary care pediatric intensive care unit (PICU). METHODS The medical charts of all patients above 5 years of age admitted to the PICU at Nationwide Children's Hospital, Columbus, OH, USA, with status asthmaticus from 2000 to 2007 were reviewed retrospectively. Data from 222 encounters by 183 children were analyzed. RESULTS The mean age at admission in years was 11 ± 3.8. The median PICU stay was 1 day (range, 1-12 days) and median hospital stay was 3 days. The ventilated group (n = 17) stayed a median of 2 days longer in the PICU and hospital. Nearly half of the children (n = 91; 50%) did not receive daily controller asthma medications. Adherence to asthma medications was reported in 125 patient charts of whom 43 (34%) were compliant. Exposure to smoking was reported in 167 of whom 70 (42%) were exposed. Among patients receiving metered dose inhaler (MDI), only 39 (18%) were using it with a spacer. Among 105 patient charts asthma severity data were available, of them 21 (20%) were labeled as mild intermittent, 29 (28%) were mild persistent, 26 (25%) were moderate persistent, and 29 (28%) were severe persistent. Compared to children with only one PICU admission during the study period (n = 161), children who had multiple PICU admissions (n = 22) experienced more prior emergency department visits and hospitalizations for asthma symptoms. There were no fatalities. CONCLUSION Asthmatics with any disease severity are at risk for life-threatening asthma exacerbations requiring PICU stay, especially those who are not adherent with their daily medications.

Abstract
Asthma is the most common chronic condition affecting children and a prominent chief complaint in pediatric emergency departments (ED). We aimed to determine parental preference between short- and long-term courses of oral corticosteroids for use in children with mild to moderate asthma presenting to our pediatric ED with acute asthma exacerbations. We surveyed parents of asthmatic children who presented to our pediatric ED from August 2011 to April 2012. Questions characterized each patient's asthma severity, assessed parental preference among systemic steroid and inhaled medication delivery options for acute asthma management, and inquired about compliance, medication costs, and intention to follow up. The majority of our parents prefer the use of 1 to 2 days of steroids to 5 days for acute asthma exacerbations in the ED. Thus, dexamethasone is an attractive alternative to prednisone/prednisolone and should be considered in the management of acute asthma exacerbations in the ED.

Abstract
OBJECTIVES The objective was to evaluate the cost-effectiveness of dexamethasone versus prednisone for the treatment of pediatric asthma exacerbations in the emergency department (ED). METHODS This was a cost-effectiveness analysis using a decision analysis model to compare two oral steroid options for pediatric asthma patients: 5 days of oral prednisone and 2 days of oral dexamethasone (with two dispensing possibilities: either a prescription for the second dose or the second dose dispensed at the time of ED discharge). Using estimates from published studies for rates of prescription filling, compliance, and steroid efficacy, the projected rates of ED relapse visits, hospitalizations within 7 to 10 days of the sentinel ED visit, direct costs, and indirect costs between the two arms were compared. RESULTS The rate of return to the ED per 100 patients within 7 to 10 days of the sentinel ED visit for the prednisone arm was 12, for the dexamethasone/prescription arm was 10, and for the dexamethasone/dispense arm was 8. Rates of hospitalization per 100 patients were 2.8, 2.4, and 1.9, respectively. Direct costs per 100 patients for each arm were $20,500, $17,200, and $13,900, respectively. Including indirect costs related to missed parental work, total costs per 100 patients were $22,000, $18,500, and $15,000, respectively. Total cost savings per 100 patients for the dexamethasone/prescription arm compared to the prednisone arm was $3,500 and for the dexamethasone/dispense arm compared to the prednisone arm was $7,000. CONCLUSIONS This decision analysis model illustrates that use of 2 days of dexamethasone instead of 5 days of prednisone at the time of ED visit for asthma leads to a decreased number of ED visits and hospital admissions within 7 to 10 days of the sentinel ED visit and provides cost savings.

Abstract
OBJECTIVE To determine whether systemic corticosteroids are under-prescribed (as measured by current NIH treatment guidelines) for children in the United States seen in the emergency department (ED) for acute asthma, and to identify factors associated with prescribing systemic corticosteroids. METHODS We used data from the 2001-2007 National Hospital Ambulatory Medical Care Survey. The study population was children ≤ 18 years old in the ED with a primary diagnosis of asthma (ICD-9-CM code 493.xx) who received bronchodilator(s). The primary outcome was receipt of a systemic corticosteroid in the ED. Independent variables included patient-level (e.g., demographics, insurance, fever, admission), physician-level (provider type, ancillary medications and tests ordered), and system-level factors (e.g., ED type, geographic location, time of day, season, year). We used multivariable logistic regression techniques to identify factors associated with systemic corticosteroid treatment. RESULTS Systemic corticosteroids were prescribed at only 63% of pediatric acute asthma visits to EDs. Over the study period, there was a trend toward increasing systemic corticosteroid use (p for trend = .05). After adjusting for potential confounders, patients were more likely to receive systemic corticosteroids when treated in pediatric EDs than in general EDs (OR = 2.45; 95% CI: 1.26-4.77). CONCLUSION Systemic corticosteroids are under-prescribed for children who present to EDs with acute asthma exacerbations. Pediatric EDs are more likely than general EDs to treat asthma exacerbations with systemic corticosteroids. Differences in the process of care in pediatric ED settings (compared to general EDs) may increase the likelihood of adherence to NIH treatment guidelines.

Abstract
The management of acute asthma exacerbations in children remains controversial and the latest guidelines (Expert Panel Report [EPR]-3 2007 and the Global Initiative of Asthma 2008) leave several questions unanswered. This review summarizes the most up-to-date information on the practical prevention and control of asthma attacks in children, and describes the 20-year experience of a major tertiary asthma clinic with the administration of inhaled corticosteroids in this setting. The following subjects are discussed: the knowledge and skills required by the parents regarding asthma and its treatment, how to prevent or minimize exacerbations in asthmatic children, the drugs used in the treatment of exacerbations and their order of administration, and the steps to follow after discharge from the emergency department or after a severe asthma exacerbation. The efficacy of inhaled corticosteroids in the management of acute asthma exacerbations in children, both at home and in the emergency department, is discussed in detail. The goal of asthma-management programs is to arm parents with the skills and knowledge to prevent, detect and successfully control most exacerbations of asthma in children at home.

Abstract
OBJECTIVE To report the outcome of children with life-threatening asthma (LTA) admitted to a university Pediatric Intensive Care Unit (PICU). METHODS Retrospective study between October 2002 and May 2010 was carried out. Every child with LTA and bronchospasm was included. RESULTS 30 admissions of 28 patients (13 M, 17 F) were identified which accounted for 3% of total PICU admissions (n = 1033) over the study period. The majority of patients were toddlers (median age 3.1 years). Few had past history of prematurity, lung diseases, or neuro-developmental conditions. Approximately half had previous admissions for asthma and one-forth with history of non-compliance to recommended treatment for asthma. One patient had parainfluenza virus and one had rhinovirus isolated. None of these factors were associated with need for mechanical ventilation (n = 6 admissions). Comparing with patients who did not receive mechanical ventilation, ventilated children had significantly higher PIM2 score (1.65 versus 0.4, p < 0.001), higher PCO2 levels (9.3 kPa versus 5.1 kPa, p = 0.01) and longer PICU stay (median 2.5 days versus 2 days, p = 0.03) The majority of patients received systemic corticosteroids, intravenous or inhaled bronchodilators. There was one pneumothorax but no death in this series. CONCLUSIONS LTA accounted for a small percentage of PICU admissions. Previous hospital admissions for asthma and history of non-compliance were common. Approximately one quarters required ventilatory supports. Regardless of the need for mechanical ventilation, all patients survived with prompt treatment.

Abstract
The role of inhaled corticosteroids (ICS) as rescue medication for asthma exacerbations in children is controversial. ICS have the important potential advantage of direct delivery to the airways, which substantially reduces the risk of the adverse systemic effects that may be associated with oral corticosteroids. Oral corticosteroids are still preferred for severe attacks. Five randomized, controlled studies performed at home and six performed in the emergency department indicated that ICS are at least as effective as the oral route. Our pediatric out-patient asthma clinic has been using ICS for asthma exacerbations for more than 25 years. The key elements to success are the administration of repetitive doses at least four-times higher than the maintenance dose and parental adherence to the treatment plan. This article reviews the findings in the literature favoring this approach and describes our methodology in detail.

Abstract
BACKGROUND The National Heart, Lung and Blood Institute asthma guidelines recommend that parents communicate with a clinician during childhood asthma exacerbations when symptoms worsen or do not improve with initial therapy. This study tested the hypothesis that communication by parents with a clinician before an Emergency Department visit was associated with more appropriate medication administration for children with asthma exacerbations. METHODS This was a retrospective cohort study using data gathered from parents of children presenting with an asthma exacerbation to the emergency department. The communicating cohort included parents who communicated by telephone with a clinician during the exacerbation and the non-communicating cohort included parents who did not. Multivariate logistic regression models were used to test three hypotheses; communication with a clinician is associated with (1) administration of short-acting beta-agonists (SABAs), (2) increased dosing frequency of SABAs, and (3) administration of an oral corticosteroid. RESULTS A total of 199 subjects were enrolled, with 104 (52.3%) in the communicating and 95 (47.7%) in the non-communicating cohort. There was an association between communication and provider practice type, with children who received routine care from a private practice provider more likely to communicate with the clinician than children in hospital-based clinics or community health centers (Adjusted OR 1.9, 95% CI 1.0-3.7). Impoverished children and children insured by Medicaid were less likely to communicate with a clinician (controlling for provider type). Parents who communicated with a clinician were more likely to administer a SABA (adjusted OR 3.6, 95% CI 1.3-9.4) and an oral corticosteroid (adjusted OR 3.3, 95% CI 1.3-8.4) but were not more likely to administer a SABA with increased dosing frequency (adjusted OR 0.9, 95% CI 0.5-1.6). CONCLUSIONS Parents of children with asthma exacerbations who communicated with clinicians were more likely to administer SABAs and an oral corticosteroid before bringing their child to an emergency department. Frequency of SABA dosing was not associated with communication. Clinicians providing telephone advice to parents need to provide explicit instructions about medication administration, emphasizing the frequency with which SABAs should be administered.

Abstract
OBJECTIVE To determine whether a 5-day course of oral prednisolone is superior to a 3-day course in reducing the 2-week morbidity of children with asthma exacerbations who are not hospitalised. DESIGN, SETTING AND PARTICIPANTS Double-blind randomised controlled trial of asthma outcomes following a 5-day course of oral prednisolone (1 mg/kg) compared with a 3-day course of prednisolone plus placebo for 2 days. Participants were children aged 2-15 years who presented to the emergency departments of three Queensland hospitals between March 2004 and February 2007 with an acute exacerbation of asthma, but were not hospitalised. Sample size was defined a priori for a study power of 90%. MAIN OUTCOME MEASURES Difference in proportion of children who were symptom-free at Day 7, as measured by intention-to-treat (ITT) and per-protocol analysis; quality of life (QOL) on Days 7 and 14. RESULTS 201 children were enrolled, and there was an 82% completion rate. There was no difference between groups in the proportion of children who were symptom-free (observed difference, 0.04 [95% CI, - 0.09 to 0.18] by ITT analysis; 0.04 [95% CI, - 0.17 to 0.09] by per-protocol analysis). There was also no difference between groups in QOL (P = 0.42). The difference between groups for the primary outcome was within the equivalence range calculated post priori. CONCLUSION A 5-day course of oral prednisolone confers no advantage over a 3-day course for children with asthma exacerbations who are not hospitalised.

Abstract
BACKGROUND Clinical decisions which impact directly on patient safety and quality of care are made during acute asthma attacks by individual doctors based on their knowledge and experience. Decisions include administration of systemic corticosteroids (CS) and oral antibiotics, and admission to hospital. Clinical judgement analysis provides a methodology for comparing decisions between practitioners with different training and experience, and improving decision making. METHODS Stepwise linear regression was used to select clinical cues based on visual analogue scale assessments of the propensity of 62 clinicians to prescribe a short course of oral CS (decision 1), a course of antibiotics (decision 2), and/or admit to hospital (decision 3) for 60 "paper" patients. RESULTS When compared by specialty, paediatricians' models for decision 1 were more likely to include level of alertness as a cue (54% vs 16%); for decision 2 they were more likely to include presence of crepitations (49% vs 16%) and less likely to include inhaled CS (8% vs 40%), respiratory rate (0% vs 24%) and air entry (70% vs 100%). When compared to other grades, the models derived for decision 3 by consultants/general practitioners were more likely to include wheeze severity as a cue (39% vs 6%). CONCLUSIONS Clinicians differed in their use of individual cues and the number included in their models. Patient safety and quality of care will benefit from clarification of decision-making strategies as general learning points during medical training, in the development of guidelines and care pathways, and by clinicians developing self-awareness of their own preferences.

Abstract
Factors resulting in intensive care unit (ICU) admissions for asthma exacerbations remain largely unclear. We compared ICU and general pediatric ward admissions for asthma exacerbations. Charts of 56 (2- to 18-year-old) patients admitted consecutively to the ICU during a 1-year period for asthma exacerbations were compared with charts of 56 age-, sex-, race-, and era-matched patients admitted to a general pediatric ward. Few patients in both groups received oral steroids before admission. Children with different chronic asthma severities had comparable severities of acute exacerbation. In conclusion, acute asthma exacerbations dissociate in severity from chronic asthma and are under-treated with systemic corticosteroids.

Abstract
OBJECTIVE To examine whether nebulized budesonide inhalation suspension treatment reduces asthma-related emergency department visit/hospitalization recurrence risk in children compared with other asthma medications, particularly non-nebulized inhaled corticosteroids. RESEARCH DESIGN AND METHODS Longitudinal, retrospective claims analysis of data from a managed care organization database in the United States (July 1, 2000-June 30, 2002). Participants were children aged < or = 8 years with an asthma diagnosis and asthma-related emergency department visit or hospitalization (index event). Asthma medication use, evaluated by asthma-related prescriptions < or = 30 days after the index event, determined treatment groups. MAIN OUTCOME MEASURE Emergency department visit/hospitalization recurrence risk from post-index day 31-180 across treatment groups. RESULTS Of 10,176 patients with an index event, 13% experienced a post-index recurrence. For patients receiving asthma prescriptions < or = 30 days after the index event, those receiving budesonide inhalation suspension showed a significant reduction in emergency department visit/hospitalization recurrence risk compared with those not prescribed this treatment (adjusted hazard ratio, 0.71; 95% confidence interval, 0.57-0.89). For patients receiving asthma controller medication in the post-index period, those receiving budesonide inhalation suspension had a significantly lower recurrence risk than patients receiving prescriptions for other controller medications (hazard ratio, 0.71; 95% confidence interval, 0.52-0.97). Recurrence risk was significantly reduced (53%) in patients receiving budesonide inhalation suspension prescriptions compared with non-nebulized inhaled corticosteroid prescriptions (hazard ratio, 0.47; 95% confidence interval, 0.28-0.78). CONCLUSION For children aged < or = 8 years, budesonide inhalation suspension treatment after an asthma-related emergency department visit/hospitalization was associated with a significantly reduced risk of recurrence compared with other asthma medications and with non-nebulized inhaled corticosteroids. Because this was an observational study, results should be interpreted cautiously. However, this study allowed evaluation of treatment in real-world practice settings not often included in clinical trials.

Abstract
AIM Intermittent wheezing illnesses, which include viral-associated wheeze and asthma, are among the most common reasons for children to present urgently to a doctor. The objectives of this systematic review were to assess the benefits and harmful effects of parent-initiated oral corticosteroids (PIOCS) in the management of intermittent wheezing illness in children. METHODS The Cochrane Airways Group Specialised Register, The Cochrane Controlled Trials Register (CENTRAL), MEDLINE, EMBASE, LILACS, Web of Science and Dissertation Abstracts were searched. Only randomised clinical trials studying patients aged between 1 and 18 years, with an intermittent wheezing illness were included. RESULTS From 572 original citations, a total of two randomised clinical trials (303 randomised participants) were included. The quality of the included trials was high; however, marked clinical heterogeneity precluded a meta-analysis. The two trials did not find evidence that PIOCS are associated with a benefit in terms of hospital admissions, unscheduled medical reviews, symptoms scores, or bronchodilator use. CONCLUSION Limited current evidence is available and it is inconclusive regarding the benefit from PIOCS therapy in the treatment of intermittent wheezing illnesses in children. Oral corticosteroids have a clearly defined role in the management of acute asthma in the hospital setting. Therefore, it is reasonable for clinicians to recommend PIOCS when (i) the child has a history of severe acute asthma; and (ii) the parents are able to assess asthma status. However, widespread use of PIOCS cannot be recommended until the benefits and harms can be clarified further.

Abstract
In the first National Heart Lung and Blood Institute and Global Initiative for Asthma (GINA) guidelines, the level of symptoms and airflow limitation and its variability allowed asthma to be subdivided by severity into four subcategories (intermittent, mild persistent, moderate persistent, and severe persistent). It is important to recognize, however, that asthma severity involves both the severity of the underlying disease and its responsiveness to treatment. Thus, the first update of the GINA guidelines defined asthma severity depending on the clinical features already proposed as well as the current treatment of the patient. In addition, severity is not a fixed feature of asthma, but may change over months or years, whereas the classification by severity suggests a static feature. Moreover, using severity as an outcome measure has limited value in predicting what treatment will be required and what the response to that treatment might be. Because of these considerations, the classification of asthma severity is no longer recommended as the basis for treatment decisions, a periodic assessment of asthma control being more relevant and useful.

Abstract
AIM To determine the effect of implementing a clinical pathway, using evidence-based clinical practice guidelines, for the emergency care of children and adolescents with asthma. METHODS A prospective, before-after, controlled trial was conducted, which included patients aged 1-18 years who had acute exacerbations of asthma treated in a tertiary care paediatric emergency department. Data were collected for identical 2-month seasonal periods before and after implementation of the clinical pathway to determine hospitalisation rate and other outcomes. For 2 weeks after emergency visits, the rate at which patients returned to emergency care for worsening asthma was evaluated. A multidisciplinary panel, using national guidelines and a systematic review, developed the pathway. RESULTS 267 patients were studied. The rate of hospitalisation was significantly lower in the post-implementation group (10/74; 13.5%) than in the pre-implementation control group (53/193; 27.5%; p = 0.02; number needed to treat 7.1). All reduction in hospitalisation occurred in children with moderate to severe asthma exacerbation. After implementation of the clinical pathway, the rate of administration of oral corticosteroids to patients with moderate or severe exacerbations increased from 71% to 92% (p = 0.01), and significantly more patients received beta2-agonists in the first hour (p = 0.02). No significant change in relapse to acute care occurred within 2 weeks (p = 0.19). CONCLUSIONS An evidence-based clinical pathway for children and adolescents with moderate to severe exacerbations of acute asthma markedly decreases their rate of hospitalisation without increased return to emergency care.

Abstract
OBJECTIVE To compare the efficacy of a single dose of oral dexamethasone (Dex) versus 5 days of twice-daily prednisolone (Pred) in the management of mild to moderate asthma exacerbations in children. STUDY DESIGN A prospective, randomized, double-blinded trial of children 2 to 16 years of age who presented to the emergency department (ED) with acute mild to moderate asthma exacerbations. Subjects received single-dose oral Dex (0.6 mg/kg to a maximum of 18 mg) or oral Pred (1 mg/kg per dose to a maximum of 30 mg) twice daily for 5 days. After discharge, subjects were contacted by telephone at 48 h to assess symptoms and reevaluated in the ED in 5 days. The primary outcome was the number of days needed for Patient Self Assessment Score to return to baseline (score of 0-0.5). MAIN RESULTS Baseline characteristics of the 2 groups were similar. The mean number of days needed for Patient Self Assessment Score to return to baseline (0-0.5) in the Dex and Pred groups were 5.21 versus 5.22 days, respectively (mean difference, -0.01; confidence interval, -0.70, 0.68). Pulmonary index scores were similar in both groups at initial presentation, initial ED discharge and at the day 5 follow-up visit. At the first visit, mean time to discharge was 3.5 h (+/-1.93)for Dex and 4.3 h (+/-3.67) for Pred (mean difference, -0.8; confidence interval, -1.8, 0.2). Initial admission rate was 9% (Dex) versus 13.4% (Pred). There was no significant difference in the number of salbutamol therapies needed in the ED nor at home after discharge. For subjects discharged home, the admission rate after initial discharge was 4.9% (Dex) versus 1.8% (Pred), resulting in overall hospital admission rates of 13.4% (Dex) and 14.9% (Pred). CONCLUSION A single dose of oral Dex (0.6 mg/kg) is no worse than 5 days of twice-daily prednisolone (1 mg/kg per dose) in the management of children with mild to moderate asthma.

Abstract
BACKGROUND Intermittent wheezing illnesses, which include viral associated wheeze and asthma, are amongst the most common reasons for children to present urgently to a doctor. Whether parents should commence oral corticosteroids (OCS) for an episode of acute wheeze in their child without waiting for a medical review is an important question, as the potential benefits of early oral corticosteroid intervention have to be weighed against the potential adverse effects of treatment. OBJECTIVES The objectives were to assess the benefits and harmful effects of parent-initiated OCS, in the management of intermittent wheezing illnesses in children, based on the results of randomised clinical trials. SEARCH STRATEGY The Cochrane Airways Group Specialised Register, The Cochrane Controlled Trials Register (CENTRAL), MEDLINE, EMBASE, LILACS, Web of Science and Dissertation Abstracts were combined (all searched November 2005). Manufacturers and researchers in the field were also contacted. SELECTION CRITERIA Only randomised clinical trials studying patients aged between one and eighteen years old, with an intermittent wheezing illness (asthma, viral wheeze, preschool viral wheeze) were included. Interventions encompassed OCS at any dose or duration versus placebo or other drug combination. The trials could be unpublished or published and no language limitations were applied. DATA COLLECTION AND ANALYSIS Two reviewers independently selected trials for inclusion, assessed trial quality and extracted the data. The statistical package (RevMan 4.2) provided by the Cochrane Collaboration was used. MAIN RESULTS From 572 original citations, a total of 2 randomised clinical trials (303 randomised participants) were included. The quality of the included trials was high; however, marked clinical heterogeneity precluded a meta-analysis. The two trials did not find evidence that parent-initiated OCS are associated with a benefit in terms of hospital admissions, unscheduled medical reviews, symptoms scores, bronchodilator use, parent and patient impressions, physician assessment, or days lost from work or school. Adverse outcomes were inadequately documented. AUTHORS' CONCLUSIONS Limited current evidence is available and it is inconclusive regarding the benefit from parent-initiated OCS in the treatment of intermittent wheezing illnesses in children. Widespread use of this strategy cannot be recommended until the benefits and harms can be clarified further.

Abstract
Preparation for pediatric pulmonary emergencies in the office setting includes adequate training for all medical staff, properly sized and working equipment, and medications to help alleviate respiratory distress when indicated. Status asthmaticus, viral bronchiolitis, and croup account for the vast majority of respiratory emergencies encountered in the pediatric office setting. Timely application of proven approaches to assessment and treatment of these illnesses can prevent hospitalization, decrease length of hospitalizations, and save lives.

Abstract
OBJETIVO: Identificar fatores preditivos da evolução da asma aguda, a partir de características clínicas e funcionais observadas no momento da admissão de crianças em unidade de emergência. MÉTODOS: Este estudo avaliou prospectivamente 130 crianças com asma aguda, na faixa etária de um a treze anos, no momento da admissão e durante a evolução em unidade de emergência, através de escore clínico e medidas de saturação arterial de oxigênio por oximetria de pulso e do pico de fluxo expiratório. RESULTADOS: Os valores iniciais de escore clínico, saturação arterial de oxigênio medida por oximetria de pulso e pico de fluxo expiratório apresentaram correlação com o número de inalações realizadas e a necessidade do uso de corticosteróide. As médias dos valores iniciais de escore clínico e da saturação arterial de oxigênio dos pacientes que foram internados foram estatisticamente diferentes das dos que não foram internados. Os valores iniciais de escore clínico e de saturação arterial de O2 e a existência de atendimento anterior pela mesma exacerbação foram preditivos da necessidade de hospitalização das crianças. CONCLUSÕES: A medida da saturação arterial de O2 e o escore clínico foram úteis para predizer a evolução da asma aguda em crianças. A medida do pico de fluxo expiratório é de difícil obtenção e interpretação nessa condição e demonstrou ter pouca aplicação prática.

Abstract
BACKGROUND A total of 196,000 hospitalizations occur each year among the 9 million US children who have been diagnosed with asthma. Not enough is known about how to prevent pediatric asthma hospitalizations. OBJECTIVES To identify the proportion of preventable pediatric asthma hospitalizations and how such hospitalizations might be prevented, according to parents and physicians of hospitalized children with asthma. METHODS A cross-sectional survey was conducted of parents, primary care physicians (PCPs), and inpatient attending physicians (IAPs) of a consecutive series of all children who were admitted for asthma to an urban hospital in a 14-month period. RESULTS The 230 hospitalized children had a median age of 5 years; most were poor (median annual family income: 13,356 dollars), were nonwhite (93%), and had public (74%) or no (14%) health insurance. Compared with children who were hospitalized for other ambulatory care-sensitive conditions, hospitalized children with asthma were significantly more likely to be African American (70% vs 57%), to be older, and not to have made a physician visit or telephone contact before admission (52% vs 41%). Only 26% of parents said that their child's admission was preventable, compared with 38% of PCPs and 43% of IAPs. The proportion of asthma hospitalizations that were assessed as preventable varied according to the source or combination of sources, from 15% for agreement among all 3 sources to 54% as identified by any 1 of the 3 sources. PCPs (83%) and IAPs (67%) significantly more often than parents (44%) cited parent/patient-related reasons for how hospitalizations could have been prevented, including adhering to and refilling medications, better outpatient follow-up, and avoiding known disease triggers. Parents (27%) and IAPs (26%) significantly more often than PCPs (11%) cited physician-related reasons for how hospitalizations could have been avoided, including better education by physicians about the child's condition, and better quality of care. Multivariate analyses revealed that an age > or =11 years and no physician contact before the hospitalization were associated with approximately 2 times the odds of a preventable asthma hospitalization. CONCLUSIONS The proportion of asthma hospitalizations assessed as preventable varies from 15% to 54%, depending on the source. Adolescents and families who fail to contact physicians before hospitalization are at greatest risk for preventable hospitalizations. Many pediatric asthma hospitalizations might be prevented if parents and children were better educated about the child's condition, medications, the need for follow-up care, and the importance of avoiding known disease triggers.

Abstract
PURPOSE OF REVIEW Acute exacerbations of asthma are the leading cause of emergency department visits in the pediatric patient. The present review is focused on the identification of those factors that may contribute to improving the short-term outcome of children after discharge from an emergency department visit for acute asthma. RECENT FINDINGS Several recent studies have documented that children treated at the emergency department because of an asthma-related event present a high morbidity at 7 and 15 days after discharge, mainly associated with symptom persistence, need for rescue bronchodilator medication, and absenteeism from school or day nursery. A better control of the disease, particularly adequate outpatient follow-up and maintenance treatment with inhaled steroids, could improve short-term clinical outcomes. SUMMARY All efforts of emergency room management of children with asthma, identification of severity of the current exacerbation episode, and intensive treatment of the acute asthma attack have usually been directed at reducing the rates of hospitalization and the return for medical care. However, according to reported data on short-term morbidity, it is necessary to define therapeutic and follow-up strategies after treatment for acute asthma and emergency department discharge. Besides standard treatment for an acute asthma exacerbation in a pediatric emergency department, action plans should include a review of the maintenance treatment of asthma to improve underlying disease control and a strong recommendation for close follow-up by the primary care pediatrician.

Abstract
OBJECTIVES To assess the efficacy and tolerability of oral deflazacort versus oral prednisolone in acute moderate asthma in children. PATIENTS AND METHODS We performed a prospective, randomized, parallel group trial of children aged 6 to 14 years old with a diagnosis of asthma who presented to the pediatric emergency department for moderate asthma exacerbation. All patients were administered short-acting beta2-adrenergic agonists. The intervention groups received either oral deflazacort (1.5 mg/kg) or prednisolone (1 mg/kg) for 7 days. The primary outcome measure was forced expiratory volume in 1 second (FEV1) and secondary outcome measures were pulmonary symptom score index, peak expiratory flow rate (PEFR), hospitalization rate and the use of rescue beta2-agonists. Patients were evaluated at the start of treatment (visit 1), on day 2 (visit 2) and on day 7 (visit 3). RESULTS Of the 54 children enrolled, two were hospitalized on visit 2 (one from each group). Baseline clinical data were similar in both groups: FEV1: 53 and 51 %; bronchodilator test: 119 and 121 %; PEFR: 169 and 165 L/min; symptom score: 6 and 6.5 for the deflazacort and prednisolone groups, respectively. On visit 2, all measures improved: FEV1: 122.2 and 126.5 % (p < 0.05); PEFR: 164 and 149 L/min (p < 0.05); symptom score: -4.4 and -3.8 (p < 0.05), without significant differences between groups. On visit 3 all variables continued to show improvement: FEV1: 133.2 and 132.5 % (p < 0.05); PEFR: 1115.7 and 187.6 L/min (p < 0.05); symptom score: -5.4 and -5.9 (p < 0.05), without significant differences between groups. No adverse effects were reported. CONCLUSIONS Deflazacort and prednisolone show similar efficacy in improving pulmonary function and in producing clinical improvement in the management of acute moderate asthma in children.

Abstract
BACKGROUND Few studies have addressed asthma screening in the preschool age group. Early asthma recognition and intervention in preschool children may reduce costs related to unscheduled medical care and missed school and work. OBJECTIVE To facilitate an early recognition and referral process for asthma in a preschool education program in Los Angeles, CA. METHODS We administered a 7-question survey to parents and guardians of children aged 12 months to 6 years in the prekindergarten program of a large school district in Southern California. English and Spanish survey questions addressed health care use, school absenteeism, and asthma symptoms. Postsurvey reports to parents recommended clinical evaluation of children who had probable asthma. RESULTS Of the 609 surveys returned from 8 centers (> or = 80% survey return rate), 12% were positive for probable asthma and only 5.4% of these cases had been previously diagnosed. Of the 12% found to have a high probability of asthma, 3 independent factors were associated with a lower likelihood of prior asthma diagnosis: Hispanic descent; Spanish speaking; and medicine use 2 or more times per week for symptoms such as cough, chest tightness, trouble breathing, or wheezing. Symptoms at play, during the day, and at night were noted in 35% to 44% of the preschoolers. Cough was the most frequently reported symptom (71.9%, n = 424). CONCLUSIONS A school-based screening process in an early education program can help identify preschool children with a high probability of asthma and offer a basis for early recognition and intervention.
