National survey conducted among Italian pediatricians examining the therapeutic management of croup. Respir Med 2024; 226:107587. [PMID: 38522591 DOI: 10.1016/j.rmed.2024.107587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 02/10/2024] [Accepted: 03/05/2024] [Indexed: 03/26/2024]
Abstract
OBJECTIVES Practice-to-recommendations gaps exist in croup management and have not been critically investigated. This study examined the therapeutic management of croup among a national sample of Italian pediatric providers. METHODS A survey was administered online to a sample of primary care and hospital-based pediatricians. Demographic data, perception regarding disease severity, treatment and knowledge of croup, choices of croup treatment medications, and knowledge of and adherence to treatment recommendations were compared between hospital and primary care pediatricians. Oral corticosteroids alone, oral corticosteroids with or without nebulized epinephrine and nebulized epinephrine plus oral or inhaled corticosteroids were considered the correct management in mild, moderate and severe croup, respectively. The determinants for correct management were examined using multivariate logistic regression analysis. RESULTS Six hundred forty-nine pediatricians answered at least 50% of the survey questions and were included in the analysis. Providers reported extensive use of inhaled corticosteroids for mild and moderate croup. Recommended treatment for mild, moderate and severe croup was administered in 46/647 (7.1%), 181/645 (28.0%) and 263/643 (40.9%) participants, respectively. Provider's age and knowledge of Westley Croup Score were significant predictors for correct management of mild croup. Being a hospital pediatrician and perception of croup as a clinically relevant condition were significant for moderate croup. CONCLUSIONS Significant differences exist between recommended guidelines and clinical practice in croup management. This study suggests wide variability in both the treatment of croup and clinical decision making strategies among hospital and primary care pediatricians. Addressing this issue could lead to noteworthy clinical and economic benefits.

J Korean Med Sci 2024; 39:e95. [PMID: 38469967 PMCID: PMC10927388 DOI: 10.3346/jkms.2024.39.e95] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 01/11/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND Tracking national croup trends can provide important insights for childhood health management. This study aimed to analyze the incidence and drug prescription trends in Korean children over a two-decade period. METHODS This population-based study encompassed 479,783 children aged < 5 years from 2002-2019, utilizing the National Health Insurance Service-National Sample Cohort. We identified participants with a primary croup diagnosis who were admitted to or visited the emergency room. Age-specific and age-adjusted incidence rates/10,000 person-years were calculated. We assessed using orthogonal polynomial contrasts and stratified by various factors (sex, age, residential area, economic status, comorbidities, and healthcare facility types). We observed changes in the use of five medications: inhaled steroids, systemic steroids, inhaled epinephrine, antibiotics, and short-acting bronchodilators. Generalized binomial logistic regression was used to analyze factors influencing prescription strategies. RESULTS In 2002, the croup-related visits were 16.1/10,000 person-years, increasing to 98.3 in 2019 (P for trend < 0.001). This trend persisted, regardless of age, sex, region, and economic status. Children with comorbid atopic dermatitis or asthma maintained consistent croup rates, while those without comorbidities increased. Treatment trends showed decreasing antibiotic (73-47%) and oxygen use (21.3-3.4%), with increasing nebulized epinephrine (9.3-41.5%) and multiple drug prescriptions (67.8-80.3%). Primary care centers exhibited a greater increase in prescription usage and hospitalization duration than did tertiary healthcare institutions. CONCLUSION Over the past two decades, croup incidence has risen, accompanied by increased epinephrine use and decreased antibiotic prescriptions. Longer hospitalization and higher medication use were mainly observed in primary care facilities.

Antibiotic use in children hospitalised for influenza, 2010-2021: the Canadian Immunization Monitoring Program Active (IMPACT). Infection 2023:10.1007/s15010-023-02124-6. [PMID: 37930625 DOI: 10.1007/s15010-023-02124-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 10/22/2023] [Indexed: 11/07/2023]
Abstract
PURPOSE To determine characteristics associated with inappropriate antibiotic use amongst children hospitalised for influenza. METHODS We performed active surveillance for laboratory-confirmed influenza hospitalizations amongst children ≤ 16 years old at the 12 Canadian Immunization Monitoring Program Active hospitals, from September 2010 to August 2021. Antibiotic use was presumed appropriate if any of the following indications were met: age < 1 month, immunocompromised, hemoglobinopathy, laboratory-confirmed bacterial infection, radiographically confirmed pneumonia, admission to an intensive care unit and mechanical ventilation. Regression analyses were used to identify baseline and clinical characteristics associated with antibiotic use amongst patients without an appropriate indication. RESULTS Amongst 8971 children, 6424 (71.6%) received any antibiotics during their hospitalisation. Amongst the 4429 children without an appropriate indication, 2366 (53.2%) received antibiotics. Antibiotic use amongst children without appropriate indication differed between study centres, ranging from 33.2% to 66.1% (interquartile range [IQR] 50.6-56.3%); it did not change significantly over time (p-value for trend = 0.28). In multivariable analyses, older age (adjusted odds ratio [aOR] 0.97, 95% confidence interval [CI] 0.96-0.99), presence of any high-risk condition (aOR 0.80, 95% CI 0.70-0.92), influenza virus type B (aOR 0.8, 95% CI 0.70-0.91) and croup (aOR 0.64, 95% CI 0.49-0.83) were associated with less, whilst fever ≥ 38.5 °C (aOR 1.82, 95% CI 1.42-2.35) and hospitalisation duration (aOR 1.12, 95% CI 1.09-1.15) were associated with more inappropriate antibiotic use. CONCLUSIONS Over two-third of children hospitalised for influenza received antibiotics, including over half of those without an appropriate indication for antibiotic treatment. Differences amongst study centres suggest the importance of contextual determinants of antibiotic use.

Abstract
Objectives: The emergence of COVID-19 has revealed its association with croup. The objective of this study was to compare outcomes of COVID-19 related croup to non-COVID-19 related croup during the COVID-19 pandemic. Methods: This retrospective propensity matched study used data from 2020-2023 in the United States Cohort of the TriNetX database that includes 56 major health care organizations. The analysis compared the outcomes of 2 cohorts of patients between 2 months and 7 years of age: Cohort A had croup and a positive test for COVID-19 and Cohort B had croup without a positive COVID-19 test, both within 1 week before or after presentation with croup. Outcomes were death, admission to the hospital, intensive care unit (ICU) admission, respiratory rate >60, and oxygen saturation <90 within 7 days after the diagnosis of croup. Results: There were 2590 patients with COVID-19 related croup and 103,439 patients with non-COVID-19 croup. The final propensity matched cohort included 5180 patients evenly divided between groups. When both groups were compared based on outcomes after matching, there was twice the risk of the patient being admitted to the hospital with COVID-19 croup (risk ratio [RR] = 2.12; 95% confidence interval [CI] 1.59-2.84; P < 0.001). Those with COVID-19 related croup had significantly increased risk of being admitted to the ICU (RR = 4.90; 95% CI 3.11-7.73; P < 0.001). The patients with COVID-19 related croup were more likely to have a respiratory rate ≥60 (RR = 2.00; 95% CI 1.18-3.37; P = 0.008) and oxygen saturation ≤90% (RR = 2.12; 95% CI 1.21-3.70; P = 0.007). There were no deaths in the final cohorts. There were no worse outcomes in the Omicron COVID-19 related croup group. Conclusions: The patients with COVID-19 related croup exhibited more severe disease manifestations. These children were more likely to be admitted to the hospital/ICU and had more significant respiratory distress.

Abstract
OBJECTIVES Croup is the most common cause of acute upper airway obstruction in children. The benefits of treating croup with steroids are well established, with an onset of effect 30 minutes after administration. We investigated whether a 30-minute exposure to outdoor cold air might improve mild to moderate croup symptoms before the onset of action of steroids. METHODS This open-label, single-center, randomized controlled trial, enrolled children aged 3 months to 10 years with croup and a Westley Croup Score (WCS) ≥2 attending a tertiary pediatric emergency department. Participants were randomized (1:1) to either a 30-minute exposure to outdoor cold (<10°C) atmospheric air or to indoor ambient room air immediately after triage and administration of a single-dose oral dexamethasone. The primary endpoint was a decrease in WCS ≥2 points from baseline at 30 minutes. Analyses were intention to treat. RESULTS A total of 118 participants were randomly assigned to be exposed to outdoor cold air (n = 59) or indoor room temperature (n = 59). Twenty-nine of 59 children (49.2%) in the outdoor group and 14 of 59 (23.7%) in the indoor group showed a decrease in WCS ≥2 points from baseline at 30 minutes after triage (risk difference 25.4% [95% confidence interval 7.0-43.9], P = .007). Patients with moderate croup benefited the most from the intervention at 30 minutes (risk difference 46.1% [20.6-71.5], P < .001). CONCLUSIONS A 30-minute exposure to outdoor cold air (<10°C), as an adjunct to oral dexamethasone, is beneficial for reducing the intensity of clinical symptoms in children with croup, especially when moderate.

Abstract
OBJECTIVES Racemic epinephrine (RE) is commonly administered for croup in the emergency department (ED). Our objectives were to examine variation in RE use between EDs, to determine whether ED variation in RE use is associated with hospital or patient factors, and to evaluate the associations between the rates of hospital-specific ED RE use and patient outcomes. METHODS We performed a retrospective cohort study using the Pediatric Heath Information System of children aged 3 months to 10 years with croup in the ED. We used mixed-effects regression to calculate risk-standardized proportions of patients receiving RE in each ED and to analyze the relationship between risk-standardized institutional RE use and individual patient odds of hospital admission, ICU admission, and ED revisits. RESULTS We analyzed 231 683 patient visits from 39 hospitals. ED administration of RE varied from 14% to 48% of visits (median, 24.5%; interquartile range, 20.0%-27.8%). A total of 8.6% of patients were hospitalized and 1% were admitted to the ICU. After standardizing for case mix and site effects, increasing ED use of RE per site was associated with increasing patient odds of hospital admission (odds ratio [OR], 1.39-95%; confidence interval [CI], 1.01-1.91), but not ICU admission (OR, 1.39; 95% CI, 0.99-1.97) or ED revisit (OR, 1.00; 95% CI, 0.92-1.09). CONCLUSIONS In this large, observational study, RE administration varied widely across EDs. Increased RE use by site was associated with increased odds of hospital admission for individual patients when controlling for patient factors. These results suggest further standardization of RE use in children with croup is warranted.

Abstract
Objectives A remarkable increase in the number of patients presenting with tracheal complications after prolonged endotracheal intubation and mechanical ventilation for the management of the severe COVID-19 - associated respiratory failure has been observed. In this study, we assessed the postoperative outcomes of tracheal resection in COVID-19 patients. Methods We conducted a retrospective study in which all patients with a history of prolonged invasive mechanical ventilation due to COVID-19 infection, who were treated with tracheal resection and reconstruction, were included. The primary objective was in-hospital mortality and postoperative reintervention rate. The secondary objective was the time to tracheal restenosis. Results During the 16-month study period, 11 COVID-19 patients with tracheal complications underwent tracheal resection with end-to-end anastomosis. Mean patient age was 51.5 ± 9 years, and the majority were male (9 patients). Eight patients were referred for management of post-intubation tracheal stenosis and 3 for tracheoesophageal fistula. Eight patients had a history of tracheostomy during the COVID-19 infection hospitalization. There was one in-hospital death (9.1%) due to septicemia in the Intensive Care Unit, approximately two months after the operation. Postoperatively, 32 reinterventions were required for tracheal restenosis due to granulation tissue formation. The risk for reintervention was higher during the first 3 months after the index operation. Four patients developed tracheal restenosis (36.4%) and two of them required endotracheal stent placement during the follow up period. Conclusions Tracheal resection and reconstruction after COVID-19 infection is associated with a high reintervention rate postoperatively. Such patients require close follow up in expert interventional pulmonology units and physicians should be on high alert for the early diagnosis and optimal management of tracheal restenosis.

Abstract
BACKGROUND Glucocorticoids are the mainstay for the treatment of croup. The existing evidence demonstrates that glucocorticoids are effective in the treatment of croup in children. However, updating the evidence on their clinical relevance in croup is imperative. This is an update to a review first published in 1999, and updated in 2004, 2011, and 2018. OBJECTIVES To investigate the effects and safety of glucocorticoids in the treatment of croup in children aged 18 years and below. SEARCH METHODS We searched the Cochrane Library, which includes the Cochrane Central Register of Controlled Trials (CENTRAL; 2022 Issue 9), Ovid MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Ovid MEDLINE (1946 to 4 March 2022), Embase (Ovid) (1974 to 4 March 2022). We also searched the WHO ICTRP and ClinicalTrials.gov on 4 March 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) in children (aged 18 years and below) with croup. We assessed the effect of glucocorticoids compared to the following: placebo, any other pharmacologic agents, any other glucocorticoids, any combination of other glucocorticoids, given by different modes of administration, or given in different doses. The included studies must have assessed at least one of our primary outcomes (defined as the change in croup score or return visits, (re)admissions to the hospital or both) or secondary outcomes (defined as the length of stay in hospital or emergency departments, patient improvement, use of additional treatments, or adverse events). DATA COLLECTION AND ANALYSIS Review authors independently extracted data, with another review author verified. We entered the data into Review Manager 5 for meta-analysis. Two review authors independently assessed studies for risk of bias using the Cochrane risk of bias tool. Two review authors assessed the certainty of the evidence for the primary outcomes using the GRADE approach. MAIN RESULTS This updated review includes 45 RCTs with a total of 5888 children, an increase of two RCTs with 1323 children since the last update. We also identified one ongoing study and one study awaiting classification. We assessed most studies (98%) as at high or unclear risk of bias. Any glucocorticoid compared to placebo Compared to placebo, glucocorticoids may result in greater reductions in croup score after two hours (standardised mean difference (SMD) -0.65, 95% confidence interval (CI) -1.13 to -0.18; 7 RCTs, 426 children; low-certainty evidence); six hours (SMD -0.76, 95% CI -1.12 to -0.40; 11 RCTs, 959 children; low-certainty evidence); and 12 hours (SMD -1.03, 95% CI -1.53 to -0.53; 8 RCTs, 571 children; low-certainty evidence). The evidence for change in croup score after 24 hours is very uncertain (SMD -0.86, 95% CI -1.40 to -0.31; 8 RCTs, 351 children; very low-certainty evidence). One glucocorticoid compared to another glucocorticoid There was little to no difference between prednisolone and dexamethasone for reduction in croup score at two-hour post-baseline score (SMD 0.06, 95% CI -0.06 to 0.18; 1 RCT, 1231 children; high-certainty evidence). There was likely little to no difference between prednisolone and dexamethasone for reduction in croup score at six-hour post-baseline score (SMD 0.21, 95% CI -0.21 to 0.62; 1 RCT, 99 children; moderate-certainty evidence). However, dexamethasone probably reduced the return visits or (re)admissions for croup by almost half (risk ratio (RR) 0.55, 95% CI 0.28 to 1.11; 4 RCTs, 1537 children; moderate-certainty evidence), and showed a 28% reduction in the use of supplemental glucocorticoids as an additional treatment (RR 0.72, 95% CI 0.53 to 0.97; 2 RCTs, 926 children). Dexamethasone given in different doses Compared to 0.15 mg/kg, 0.60 mg/kg dexamethasone probably reduced the severity of croup as assessed by the croup scoring scale at 24-hour postbaseline score (SMD 0.63, 95% CI 0.16 to 1.10; 1 RCT, 72 children; moderate-certainty evidence); however, this was not the case at two hours (SMD -0.27, 95% CI -0.76 to 0.22; 2 RCTs, 861 children; high-certainty evidence). There was probably no reduction at six hours (SMD -0.45, 95% CI -1.26 to 0.35; 3 RCTs, 178 children; moderate-certainty evidence), and the evidence at 12 hours is very uncertain (SMD -0.60, 95% CI -4.39 to 3.19; 2 RCTs, 113 children; very low-certainty evidence). There was little to no difference between doses of dexamethasone in return visits or (re)admissions of children or both (RR 0.91, 95% CI 0.71 to 1.17; 3 RCTs, 949 children; high-certainty evidence) or length of stay in the hospital or emergency department (mean difference 0.12, 95% CI -0.32 to 0.56; 2 RCTs, 892 children). The need for additional treatments, such as epinephrine (RR 0.78, 95% CI 0.34 to 1.75; 2 RCTs, 885 children); intubation (risk difference 0.00, 95% CI -0.00 to 0.00; 2 RCTs, 861 children); or use of supplemental glucocorticoids (RR 0.77, 95% CI 0.51 to 1.15; 2 RCTs, 617 children), also did not differ between doses of dexamethasone. There were moderate to high levels of heterogeneity in the analyses for most comparisons. Adverse events were observed for some of the comparisons reported in the review. AUTHORS' CONCLUSIONS The evidence that glucocorticoids reduce symptoms of croup at two hours, shorten hospital stays, and reduce the rate of return visits or (re)admissions has not changed in this update. A smaller dose of 0.15 mg/kg of dexamethasone may be as effective as the standard dose of 0.60 mg/kg. More RCTs are needed to strengthen the evidence for effectiveness of low-dose dexamethasone at 0.15 mg/kg to treat croup.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:315-321. [PMID: 36184023 DOI: 10.1016/j.jaip.2022.09.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 08/30/2022] [Accepted: 09/16/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND Croup is a prevalent respiratory disorder in early childhood most often caused by parainfluenza virus infections. There are no preventive strategies; therefore, we investigated the potential effects of prenatal micronutrient supplementations. OBJECTIVE To investigate the supplementation effects of (1) 2.4-g n-3 long-chained polyunsaturated fatty acid (n-3 LCPUFA) (fish oil) versus olive oil and (2) high-dose (2800 IU/d) versus standard-dose (400 IU/d) of vitamin D from pregnancy week 24 until 1 week after birth on the risk for offspring croup during the double-blinded first 3 years of life in a secondary analysis of a 2 × 2 factorial designed randomized controlled trial. METHODS The study was completed in the Danish population-based single-center Copenhagen Prospective Studies on Asthma in Childhood 2010 mother-child cohort, which included 736 pregnant women. Croup was diagnosed by physicians' clinical examinations and medical record checks. Potential mediating mechanisms were investigated using blood metabolomics, airway cytokines, and airway microbiome. RESULTS Of 695 children, 97 had croup before age 3 years (14%). The risk of croup was reduced in the n-3 LCPUFA (ncases / ntotal = 38/346; 11%) versus olive oil group (59 of 349 children; 17%) (hazard ratio = 0.62; 95% CI, 0.41-0.93; P = .02) and in the high-dose vitamin D group (32 of 295 children; 11%) versus the standard-dose group (51 of 286 children; 18%) (hazard ratio = 0.60; 95% CI, 0.38-0.93; P = .02). There was no evidence of interaction or additive effects between the supplements (Pinteraction = .56). Furthermore, the results did not change when they were adjusted for each other, persistent wheeze, and lower respiratory tract infection. CONCLUSIONS This analysis of the double-blinded period of the Copenhagen Prospective Studies on Asthma in Childhood 2010 randomized controlled trial of n-3 LCPUFA and high-dose vitamin D supplementation during pregnancy demonstrated a reduced risk of croup in early childhood.

[PMID: 36291478 PMCID: PMC9599993 DOI: 10.3390/children9101542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 09/27/2022] [Accepted: 10/08/2022] [Indexed: 11/07/2022]
Abstract
Omicron, a recent variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is currently globally dominating. We reviewed the etiology and epidemiology of croup over an approximately 5-year period, with an emphasis on the recent dominance of the Omicron variant. Children less than 5 years of age seen in the emergency department with diagnosis of croup from two large national tertiary hospitals were collected for the period from January 2018 through March 2022. Viral etiologies of the patients were compared with national surveillance data upon circulating respiratory viruses in the community. A total number of 879 croup cases were recognized during the study period. The most common pathogen was SARS-CoV-2 (26.9%), followed by HRV (23.8%), PIV1 (14.6%), PIV3 (13.1%), and CoV NL63 (13.1%), among seventeen respiratory viral pathogens tested by polymerase chain reaction. The viral identification rate was significantly higher in the Omicron period, with most of the pathogens identified as SARS-CoV-2. In the Omicron period, with the exponential increase in the number of COVID-19 cases in the community, croup associated with SARS-CoV-2 significantly increased, with a high detection rate of 97.2% (35 of 36) among croup cases with pathogen identified. The etiologic and epidemiologic data before and throughout the COVID-19 pandemic indicate that the association between croup and infection with the SARS-CoV-2 Omicron variant is highly plausible.

Abstract
OBJECTIVES To compare the effectiveness of dexamethasone versus prednisone or prednisolone on hospital resource utilization for children hospitalized with acute croup. METHODS This is a retrospective cohort study of the Pediatric Health Information System database on children aged 6 months to <6 years who were hospitalized with acute croup between January 1, 2015 and December 31, 2019. Children with a chronic complex condition, transferred from outside hospital, and/or received direction admission to ICU were excluded. Propensity score matching was used to compare length of stay (in hours), escalation of care to ICU, and the need for bronchoscopy with exposure to dexamethasone versus prednisone or prednisolone. We also compared rates of 7 day return to the emergency department and readmissions. RESULTS A total of 11 740 hospitalizations met inclusion criteria; dexamethasone was used in 95.9%; prednisone or prednisolone was used in 4.1%. In the matched cohort (n = 960), the length of stay was not significantly different between the dexamethasone and prednisone or prednisolone groups (21.3 vs 18.5 hours, P = .35). Although the rates bronchoscopy did not differ between the 2 groups, the dexamethasone cohort was more likely to require ICU transfer (P = .007). The rates of 7-day emergency department returns (2.3% vs 1.3%, P = .24) and readmissions (3.1% vs. 2.1%, P = .37) were low and not statistically different. CONCLUSIONS Hospital resource utilization did not differ significantly for children receiving dexamethasone or prednisone or prednisolone for acute croup. Both corticosteroids may be considered reasonable choices for the treatment of children hospitalized with acute croup.

Abstract
BACKGROUND Emergency department (ED) presentation for croup is thought to occur more often at night, but evidence for its diurnal variation is sparse. Our objectives were to describe the diurnal patterns of ED presentation in children with croup and to determine whether time of arrival associated with severe clinical outcomes. METHODS We conducted a retrospective cohort study using the Pediatric Health Information System. We included children 3 months to 11 years of age with an ED encounter for croup from 2016 through 2020. We quantified ED encounters by arrival hour and used generalized linear mixed-effects models to determine association between arrival time and racemic epinephrine use, hospitalization, intensive care unit (ICU) admission, and revisits. RESULTS There was considerable diurnal variation in ED visits for croup. A total of 126 186 children (60.1%) presented to the ED at night (between 8 pm and 8 am), and 83 763 children presented during the day (39.9%). Peak arrival time was 12:00 am (14 189 encounters) and the nadir was at 2:00 pm (5231 encounters). Children presenting during overnight hours had increased odds of the use of racemic epinephrine (odds ratio [OR] 1.33; 95% confidence interval [95% CI], 1.30-1.36), but reduced odds of hospitalization (OR 0.76; 95% CI, 0.73-0.78), ICU admission (OR 0.61; 95% CI, 0.58-0.68), and 3 day ED revisits (OR 0.86; 95% CI, 0.83-0.90). CONCLUSIONS Children with croup present to the ED more commonly at night. Children presenting to the ED with croup at night have greater odds of being treated with racemic epinephrine, but reduced odds of hospitalization, ICU admission, and return visits.

Abstract
BACKGROUND Studies have found infrequent interventions after croup admission. Our objectives were to achieve 25% reduction in (1) admission rate and (2) neck radiograph utilization among patients presenting to the emergency department. METHODS At our tertiary children's hospital, we implemented clustered interventions including education, guideline, and orderset integration. We included patients 3 months to 8 years old with an emergency department, observation, or inpatient encounter for croup. We excluded patients with direct or ICU admissions, complex chronic conditions, or concurrent asthma, pneumonia, or bronchiolitis. We reviewed a random sample of 60% of encounters from baseline (October 1, 2017 to September 30, 2019) and implementation (October 1, 2019 to September 30, 2020) periods. We conducted a posthoc analysis from October 1, 2017 to December 1, 2021 to assess sustainment during coronavirus disease 2019. Interrupted time series analysis was used to evaluate changes in outcome, process, and balancing measures. RESULTS There were 2906 (2123 baseline and 783 implementation) encounters included. Extrapolating preintervention trend estimates, the baseline admission rate of 8.7% decreased to 5.5% postintervention (relative decrease 37% [95% confidence interval: 8 to 66]) and sustained over 26 months after implementation. Admission rate in patients receiving 2 or fewer racemic epinephrine was significantly lower in implementation (1.7%) compared with baseline (6.3%), relative decrease of 72% (95% confidence interval: 68 to 88). There were no significant changes in neck radiographs, length of stay, or revisits. CONCLUSIONS Croup quality improvement interventions were associated with a significant decrease in hospital admissions with no increase in revisits.

Abstract
AIM Adherence to croup management recommendations has been poorly investigated. This study aimed to describe the treatment patterns in two paediatric emergency departments and analyse the adherence to recommendations. METHODS We conducted a retrospective chart review of children diagnosed with croup in two Italian pediatric emergency departments in 2017. Data on clinical presentation, corticosteroid administration and home therapy were collected. Length of stay, hospitalisation and re-access rates were compared among different corticosteroid treatment groups. RESULTS We enrolled 632 patients (61.1% males) with a mean age of 42.8±55.1 months. Corticosteroids were administered to 403 (63.8%) children in the emergency departments. Dexamethasone was administered to 1 (0.4%) patient. Inhaled and oral corticosteroids were given to 342 (54.1%) and 226 (35.8%) patients, respectively. Home therapy was prescribed for 603 (95.4%) patients, either with inhaled (86.2%) and/or oral (43.8%) corticosteroids. The re-access rate was 2.8%. The actual pharmaceutical costs were an estimated 10 times higher than they would have been if the recommendations had been followed. CONCLUSION A significant gap between the evidence and clinical practice for croup treatment was observed. Improving adherence to the recommendations could lead to clinical and economic benefits.

Abstract
Clinically significant isolated viral tracheitis is scarce in adults, and upper airway obstruction caused by viral tracheitis is even more infrequent. A 74-year-old woman, who was administered low-dose steroids for two months for chronic obstructive pulmonary disease (COPD), developed dyspnea with stridor and required mechanical ventilation for respiratory failure. Chest computed tomography showed a diffuse tracheal wall thickening with luminal narrowing and peribronchial consolidation in the right upper lobe. Bronchoscopy revealed a proximal tracheal narrowing with multiple ulcerations of the tracheal mucosa surrounded by an erythematous margin. Pathologic examinations of the tracheal mucosal tissue, including immunohistochemistry, revealed a cytomegalovirus (CMV) and herpes simplex virus (HSV) infection. Furthermore, the bronchial alveolar lavage fluid was positive on the CMV real-time polymerase chain reaction. The patient was treated with intravenous ganciclovir for 44 days. The follow-up bronchoscopy 49 days after the initiation of ganciclovir revealed improved multiple ulcerations with scars. We report a rare case of tracheitis caused by coinfection with CMV and HSV in a patient with COPD who had been taking low-dose steroids for months. The case showed that CMV and HSV are potential causes of serious tracheitis and respiratory failure.

Abstract
A 62-year-old man, without any past medical history, but a current 10-pack–year smoker, consulted a pulmonologist at the outpatient department for a gradually worsening dyspnoea over 1 year. Dyspnoea occurred first at exercise but, for 1 week, he felt short of breath, even at rest. He also reported a chronic cough with white sputum and frequent blood streaks. His voice was not affected and he had no swallowing difficulties. He lost 4 kg over the previous 3 months, along with a loss of appetite and tiredness. He did not have fever, night sweats, chest pain or choke. Stridor is a sign of vital emergency that immediately orientates towards a laryngeal or tracheal obstruction. This case report focuses on the management of stridor, which comprises emergency securing of airways and parallel aetiological investigations.https://bit.ly/39CTjOg

Abstract
Background In 2019, a multidisciplinary panel of experts from eight Italian scientific paediatric societies developed a consensus document for the use of inhaled corticosteroids in the management and prevention of the most common paediatric airways disorders. The aim is to provide healthcare providers with a multidisciplinary document including indications useful in the clinical practice. The consensus document was intended to be addressed to paediatricians who work in the Paediatric Divisions, the Primary Care Services and the Emergency Departments, as well as to Residents or PhD students, paediatric nurses and specialists or consultants in paediatric pulmonology, allergy, infectious diseases, and ear, nose, and throat medicine. Methods Clinical questions identifying Population, Intervention(s), Comparison and Outcome(s) were addressed by methodologists and a general agreement on the topics and the strength of the recommendations (according to the GRADE system) was obtained following the Delphi method. The literature selection included secondary sources such as evidence-based guidelines and systematic reviews and was integrated with primary studies subsequently published. Results The expert panel provided a number of recommendations on the use of inhaled corticosteroids in preschool wheezing, bronchial asthma, allergic and non-allergic rhinitis, acute and chronic rhinosinusitis, adenoid hypertrophy, laryngitis and laryngospasm. Conclusions We provided a multidisciplinary update on the current recommendations for the management and prevention of the most common paediatric airways disorders requiring inhaled corticosteroids, in order to share useful indications, identify gaps in knowledge and drive future research.

Abstract
BACKGROUND The prehospital care of asthma, bronchiolitis and croup is directed by evidence-based Emergency Medical Services (EMS) protocols. Determining the appropriate intervention for these conditions requires Emergency Medical Technicians-Paramedics (EMT-Ps) to correctly differentiate asthma/bronchospasm, bronchiolitis, and croup. The diagnostic accuracy of EMT-Ps for these pediatric respiratory distress conditions is unknown. OBJECTIVE We hypothesized increasing provider age, years of provider experience, higher volume of pediatric cases, self-reported comfort with pediatric patients, and having children of one's own would be associated with increased accuracy in diagnosis on a validated multimedia questionnaire. METHODS This is a cross-sectional study of paramedics from a single EMS agency who completed a validated, case-based questionnaire between July and September 2018. The multimedia questionnaire consisted of four cases, each of which included patient videos and lung sound recordings. Paramedics were asked to assess the severity of distress and ascribe the correct diagnosis and prehospital intervention for each case. Each paramedic completed the questionnaire independently. We defined high questionnaire performance a priori as correctly identifying the diagnosis for ≥75% of cases and used multivariate regression to assess factors associated with high questionnaire performance. Provider age and EMS experience were reported in years and analyzed as continuous variables. Volume of pediatric cases was dichotomized to <1 and ≥1 case per shift and having children was dichotomized to either having children or not having children. RESULTS Of 514 paramedics, 420 (82%) completed the questionnaire. Overall, paramedics correctly assessed the severity of respiratory distress 92% of the time. However, they only ascribed the correct diagnosis 50% and selected the correct intervention(s) 38% of the time. Increasing age, years of experience, higher volume of pediatric cases, self-reported comfort with pediatric patients, and having children of their own were not associated with questionnaire performance. CONCLUSION Paramedics accurately assessed severity of distress in multimedia cases of asthma/bronchospasm, bronchiolitis and croup in children, but showed significant room for improvement in correctly identifying the diagnosis and in selecting appropriate intervention(s). Age, years of EMS experience, higher volume of clinical pediatric cases, self-reported comfort with pediatric patients, and having children of their own were not associated with questionnaire performance.

Abstract
We describe three previously healthy children, admitted from our emergency department (ED) to our free-standing children's hospital, as the first documented cases of croup as a manifestation of SARS-CoV-2 infection. All three cases (ages 11 months, 2 years, and 9 years old) presented with non-specific upper-respiratory-tract symptoms that developed into a barky cough with associated stridor at rest and respiratory distress. All were diagnosed with SARS-CoV-2 by polymerase chain reaction testing from nasopharyngeal samples that were negative for all other pathogens including the most common etiologies for croup. Each received multiple (≥3) doses of nebulized racemic epinephrine with minimal to no improvement shortly after medication. All had a prolonged period of time from ED presentation until the resolution of their stridor at rest (13, 19, and 21 h). All received dexamethasone early in their ED treatment and all were admitted. All three received at least one additional dose of dexamethasone, an atypical treatment occurrence in our hospital, due to each patient's prolonged duration of symptoms. One child required heliox therapy and admission to intensive care. All patients were eventually discharged. Pathogen testing is usually not indicated in croup, but with "COVID-19 croup," SARS-CoV-2 testing should be considered given the prognostic significance and prolonged quarantine implications. Our limited experience with this newly described COVID-19 croup condition suggests that cases can present with significant pathology and might not improve as rapidly as those with typical croup.

Abstract
BACKGROUND Croup is a common respiratory illness in children. It presents with a barky cough, stridor and hoarseness occurring secondary to inflammation of the subglottis and larynx. The clinical course of croup is well-described, however atypical presentations pose a diagnostic and management challenge. OBJECTIVES This case report and systematic review aims to synthesize the published literature on the definition, diagnosis and treatment of atypical croup. STUDY SELECTION Peer-reviewed journal publications in Ovid MEDLINE® and EMBASE from inception to January 1, 2019 in English, focusing on pediatric patients (<18 years of age) with diagnoses of atypical croup. DATA EXTRACTION Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Twelve studies involving 670 patients ranging from 6 months to 11 years of age presenting with atypical croup were selected. A variety of definitions of atypical croup were identified based on recurrence, duration of symptoms, severity, and etiology. Data on the incidence of atypical croup, the overall rates of intubation and tracheostomy, and patient characteristics leading to definitive airway management were not clearly characterized. LIMITATIONS All studies were case series, case reports or retrospective chart reviews. CONCLUSIONS Atypical croup is a poorly defined clinical entity that is used to describe recurrent, refractory, or croup-like illness that follows an uncharacteristic natural history. Our case presentation and accompanying literature review highlights the variable, but limited, information available on the diagnosis of atypical croup. Given the commonality of its use in clinical practice, we propose some guidelines around the use of the term 'atypical croup' as well as a management algorithm.

Abstract
OBJECTIVES To characterize cases of croup presenting to emergency departments (EDs) nationwide, analyze trends, and determine readmission rates. METHODS Retrospective review of the Nationwide Emergency Department Sample (2007-2014) and the National Hospital Ambulatory Medical Care Survey (2008-2015). RESULTS Both databases provided similar descriptive statistics. Annual mean of 352,388 (weighted) cases in the National Emergency Department Sample (1.35% of ED cases). Average age and male:female ratio 2.50 years and 1.95:1, respectively. Peak incidence was in autumn (October = 13.7%) with troughs in the summer (July = 3.7%). 21.3% received nebulizers, <1% laryngoscopic or airway procedures, 75.1% steroids, and 13.3% antibiotics. Of the patients receiving antibiotics, 16.0% had isolated croup. 3.0% of cases were admitted to the hospital. No trend was identified in the incidence of croup, mean age, or antibiotic and steroid usage. Hospital admission rates decreased (4.0%-2.3%) and nebulizer usage increased (14.6%-27.5%; p < 0.05). 5% of patients represented repeat admissions (were seen within 72 h prior). CONCLUSIONS Croup imposes a significant burden on the ED. Although hospital admissions decreased, annual incidence in the ED remained stable. The majority of cases are in males less than three years old, and 5.0% of patients represented readmissions. Only three-quarters received glucocorticoids despite the proven benefits, including reducing readmission rates. Antibiotic usage was high, with a large number representing potential cases of inappropriate antibiotic use.

Abstract
BACKGROUND Croup admission decision making is challenging because the rate of further interventions after stabilization is unclear. OBJECTIVE We sought to describe rates of inpatient racemic epinephrine (IRE) and additional inpatient airway interventions (IAI) (oxygen or heliox therapy, intubation, or transfer to an intensive care unit) among patients presenting to a tertiary children's hospital with croup. METHODS This was a retrospective descriptive study including patients (3 months to 8 years of age) with an emergency department (ED)/inpatient encounter for croup from January 1, 2015 to December 31, 2016 at a tertiary children's hospital. We excluded intensive care unit direct admissions and patients with bronchiolitis/asthma/pneumonia. We compared 3 groups (a weighted random 5% sample of patients evaluated in ED only, and those admitted with or without IRE/IAI) using Kruskal-Wallis, Pearson χ2, or the Fischer exact test, where appropriate. We used multivariate analysis to compare demographics and preadmission racemic epinephrine (RE) with rates of IRE/IAI in admitted patients. RESULTS We included 588 patients (194 discharged from the ED, 394 admitted). In admitted patients, 20.8% (82/394) had IRE/IAI, most commonly IRE (20.0%, 79/394). Three admitted patients (0.76%) had IAI. Overall, patients with 2 outside hospital/ED doses of RE had a 12.1% rate of IRE/IAI (23.5% if ≥3 RE doses). Patients with ≥3 preadmission RE doses were more likely to have IRE/IAI compared with 2 RE (adjusted odds ratio = 2.08 [95% confidence interval 1.15-3.76]; p = 0.02); there were no other significant associations. CONCLUSIONS We found a low rate of IRE/IAI after ED management in patients with croup and no significant associations aside from preadmission RE doses. These findings may be considered in admission decisions.

Abstract
OBJECTIVE Croup treatment usually involves a single dose of systemic dexamethasone combined with nebulized epinephrine. However, the optimal dose of l-epinephrine remains unclear. We examined whether a low dose (0.1 mg/kg) was inferior to the conventional dose (0.5 mg/kg) of 1:1000 nebulized l-epinephrine in patients with moderate to severe croup. METHODS This randomized double-blind clinical non-inferiority trial was conducted in three pediatric emergency departments from May 2015 to October 2017. Children 6 months to 5 years old with moderate to severe croup (Westley scale scores 3-11) were eligible. Subjects were randomly assigned to the conventional dose (0.5 mg/kg: maximum 5 mg) or low dose (0.1 mg/kg; maximum 1 mg) group. All subjects received 0.6 mg/kg dexamethasone. Croup scores and other vital signs were measured before and at 30, 60, 90, and 120 min after nebulized l-epinephrine administration. The primary outcome was the change in croup score after 30 min. RESULTS The final analysis included 84 patients. The groups did not differ significantly in terms of demographic parameters. At 30 min after treatment with nebulized l-epinephrine, the croup scores in both groups were significantly reduced from the baseline values (p < 0.05) and did not differ between the two groups (p = 0.42). Neither blood pressure nor heart rate differed between the two groups. CONCLUSIONS Low-dose 1:1000 l-epinephrine was not inferior in croup score reduction to the conventional dose in patients with moderate to severe croup. Clinical trial No: NCT01664507, KCT0002318.

Abstract
Las infecciones agudas del tracto respiratorio son una de las principales causas de inflamación de la vía aérea, siendo especialmente frecuentes las de origen vírico. Las infecciones de la vía aérea superior son más frecuentes en niños, y es la principal causa de hospitalización en pacientes menores de 4 años. Sin embargo, la infección aguda de los bronquios es más frecuente en adultos, siendo una de las principales causas por las que consultan en las urgencias y centros de salud. La afectación puede ir desde una en fermedad autolimitada de pocos días de evolución, hasta una obstrucción de la vía aérea potencialmente mortal.

Abstract
BACKGROUND Observation is necessary following racemic epinephrine (RE) for patients with croup. The ideal length of this observation period is unclear. OBJECTIVE To compare the rate of failed outpatient management utilizing different observation times after RE administration for croup. METHODS We performed a retrospective chart review of children with croup who required RE. Failure of treatment was defined as requiring a second RE treatment and/or returning to the pediatric emergency department for croup symptoms within 24 hours of discharge. RESULTS The primary analysis considered patients observed between 2.1 and 3 hours compared with those observed for 3.1 to 4 hours. The patients in the 2.1- to 3-hour group had a higher rate of treatment failure (16.7% vs 7.1%, OR = 2.44, P < .01). CONCLUSIONS Patients requiring RE for croup are more likely to have treatment failure if observed for between 2.1 and 3 hours as opposed to 3.1 to 4 hours.

Abstract
Epiglottitis, acute laryngitis, and croup (acute laryngotracheobronchitis) are infections of the upper airway, affecting the epiglottis, larynx, and larynx and trachea, respectively. Epiglottitis is a bacterial infection, while viruses cause nearly all cases of acute laryngitis and croup. Acute laryngitis in adults is usually self-limited. Epiglottitis, which used to be prevalent in children under age 5, is now seen more often in adults than in children. This decline in childhood epiglottitis is due to the Haemophilus influenzae type b (Hib) vaccine. Streptococci, including Streptococcus pneumoniae, are now important causes of epiglottitis. Croup is a viral infection, usually due to parainfluenza virus, that primarily affects children ages 6 months to 3 years old. Epiglottitis and croup can cause life-threatening loss of the airway, and misdiagnosis or mismanagement can result in fatalities. This chapter reviews the clinical features and treatment of these three upper respiratory tract infections.

Abstract
Asthma and croup are common inflammatory airway diseases involving the bronchus in children. However, no study has reported the effects of urbanization, sex, age, and bronchiolitis on the association of croup and its duration with asthma development. We used the Taiwan Longitudinal Health Insurance Database (LHID) to perform this population-based cohort study; here, the cluster effect caused by hospitalization was considered to evaluate the association between croup and asthma development and the risk factors for asthma in children of different age groups. We evaluated children with croup aged <12 years (n = 1204) and age-matched control patients (n = 140,887) by using Cox proportional hazards regression analysis within a hospitalization cluster. Of all 142,091 patients, 5799 (including 155 with croup [419 per 1000 person-y] and 5644 controls [106 per 1000 person-y]) had asthma during the 5-year follow-up period. During the 5-year follow-up period, the hazard ratios (HRs [95% CIs]) for asthma were 2.10 (1.81-2.44) in all children with croup, 2.13 (1.85-2.46) in those aged 0 to 5 years, and 2.22 (1.87-2.65) in those aged 6 to 12 years. Children with croup aged 7 to 9 years had a higher HR for asthma than did those in other age groups. Boys with croup had a higher HR for asthma. The adjusted HR for asthma was 1.78 times higher in children with croup living in urban areas than in those living in rural areas. In conclusion, our analyses indicated that sex, age, bronchiolitis, and urbanization level are significantly associated with croup and asthma development. According to our cumulative hazard rate curves, younger children with croup should be closely monitored for asthma development for at least 3 years.

Abstract
INTRODUCTION Respiratory viruses, such as those that cause influenza and the common cold, are a regular feature of life for the entire human population. Among people with CF, these viruses are associated with prolonged respiratory illness and show a clear association with pulmonary exacerbations which in turn are associated with lung function decline and risk of death. Human rhinovirus is the most commonly encountered respiratory viral pathogen in CF although adenovirus, bocavirus, coronavirus, influenza, parainfluenza, metapneumovirus and respiratory syncytial virus are all also responsible for infections in this population. Areas covered: This article reviews the epidemiology, clinical impact and therapeutic options for respiratory virus infection in both children and adults with CF. Expert commentary: The management of CF to date has largely focused on airway clearance strategies, nutritional support and aggressive antibacterial therapy. We highlight the significant role that respiratory viruses play in CF lung disease and argue that these pathogens represent an under-exploited target in the battle to control patients' symptoms and disease progression.

Abstract
Croup is the most common cause of stridor in children, caused by acute viral infection in most cases (parainfluenza) and mainly affects young children between 6 months and 3 years old. Treatment with oral corticosteroids and nebulized adrenaline reduced the rate of hospitalization and complications. The diagnoses of bacterial epiglottitis and viral laryngotracheobronchitis (croup) in infants and children may be confused. Epiglottitis is an acute inflammation of the epiglottis or supraglottis that may lead to the rapid onset of life-threatening airway obstruction caused by Haemophilus influenzae type b (Hib) and is an otolaryngologic emergency. Since the widespread implementation of a conjugate vaccine for Hib, the incidence of epiglottitis significantly declined in children and there was a consequent shift in disease from young children to adults. The management of epiglottitis includes securing the airways and appropriate antibiotics (ceftriaxone). Group A streptococcus is a frequent cause of pharyngitis that can be diagnosed by rapid antigen-detection test. Antibiotic treatment reduces the risk of complications, including rheumatic fever and acute glomerulonephritis.

Abstract
OBJECTIVES The Vapotherm system delivers high humidity to the airway of patients by using semipermeable tubules where heated liquid water is in contact with air. The humidified air is conducted to the patient via a heated tube. Preliminary clinical observations in infants with croup suggested that epinephrine added to the water supplying the humidity was delivered successfully in the vapor phase. The purpose of this study was to evaluate the efficiency of the delivery of epinephrine in the vapor phase and to develop the feasibility criteria for a clinical pilot study. DESIGN Thirty milligrams of epinephrine in a 1-L bag of sterile water was used as the humidification source for a Vapotherm 2000i. The output of the heated circuit was condensed and collected into a small Erlenmeyer flask via a metal coil while the whole collection system was submerged in an ice slurry to maintain the outflow temperature from the flask between 0°C and 2°C. The in vitro system was tested at 40°C with flows of 5, 10, and 15 L/min and L-epinephrine concentrations of 15, 30, and 60 mg/L. Each test was duplicated at each of the six conditions. SETTING Academic children's hospital research laboratory. PATIENTS None. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The system recovered more than 90% of the water vapor from the fully saturated air at 40°C. The epinephrine concentration recovery quantified by ultraviolet-visible spectrophotometry was 23.9% (27.5-20.4%) (mean and range) of the initial concentration. At flows of 5, 10, and 15 L/min, the delivery of epinephrine would be 1.8, 3.6, and 4.2 μg/min, respectively, which is in the therapeutic range used for parenteral infusion in young children. CONCLUSIONS The Vapotherm system can be used to deliver epinephrine in pharmacological doses to the respiratory system as a vapor and thus as an alternative to droplets by conventional nebulization.

Abstract
Luchtweginfecties in het algemeen en infecties van de bovenste luchtwegen in het bijzonder komen wereldwijd zeer veel voor en zijn de voornaamste reden om een arts te consulteren. In de niet-geïndustrialiseerde landen zijn luchtweginfecties bovendien nog steeds de belangrijkste doodsoorzaak op de kinderleeftijd. Infecties van de bovenste luchtwegen worden meestal veroorzaakt door virussen, en ook zijn er bacteriële verwekkers. Deze behoren meestal tot de eigen flora; S. pneumoniae is de belangrijkste. Op klinische gronden kan geen onderscheid worden gemaakt tussen de verschillende verwekkers van bovenste luchtweginfecties. Antibiotische behandeling van bovenste luchtweginfecties is slechts zelden nodig. Etiologische laboratoriumdiagnostiek voor influenza-achtige ziektebeelden is vooral van belang bij risicogroepen en in gezondheidsinstellingen vanwege de beschikbaarheid van antivirale behandeling en eventuele maatregelen ter voorkoming van nosocomiale verspreiding van influenzavirussen. Jaarlijkse griepvaccinatie is geïndiceerd bij risicogroepen ter voorkoming van een ernstig ziektebeloop en bij gezondheidswerkers ter voorkoming van nosocomiale verspreiding.

Abstract
Infectious processes of the trachea represent a distinct clinical entity with an evolving landscape owing to advances in airway management and vaccination practices. Untreated inflammatory processes of the trachea may present in the form of acute airway obstruction, potentially resulting in significant morbidity and even mortality. Therefore it is important to recognize the cardinal features of some of the common tracheal infectious processes to differentiate them from non-infectious pathology, as the latter is associated with a more indolent course. As with most other infectious processes of the airway, pathogens causing tracheal infection can be bacterial, viral or fungal in nature. Viral etiology represents the most common cause of laryngotracheal infection in a child. Bacterial infections of the trachea are responsible for more significant morbidity, including prolonged hospitalization, need for endotracheal intubation and even an occasional tracheostomy. The current chapter describes the clinical features and microbiology of tracheal infections at large, explores the utility of diagnostic tests, and provides an algorithm for management.

Abstract
Purpose Croup is a common pediatric respiratory illness with symptoms of varying severity. Moreover, epiglottitis is a rare disease that can rapidly progress to life-threatening airway obstruction. Although the clinical course and treatments differ between croup and epiglottitis, they are difficult to differentiate on presentation. We aimed to compare the clinical characteristics of croup and epiglottitis in Emergency Department patients. Methods The 2012 National Emergency Department Information System database of 146 Korean Emergency Departments was used to investigate patients aged ≤18 years presenting with croup or epiglottitis. Results We analyzed 19,374 croup patients and 236 epiglottitis patients. The male:female sex ratios were 1.9:1 and 2.3:1 and mean ages were 2.2±2.0 and 5.6±5.8 years, respectively. The peak incidence of croup was observed in July and that of epiglottitis was observed in May. The hospitalization rate was lower in croup than in epiglottitis patients, and the proportion of patients treated in the intensive care unit was lower among croup patients. The 3 most common chief complaints in both croup and epiglottitis patients were cough, fever, and dyspnea. Epiglottitis patients experienced dyspnea, sore throat, and vomiting more often than croup patients (P<0.05). Conclusion Both groups had similar sex ratios, arrival times, 3 most common chief complaints, and 5 most common comorbidities. Epiglottitis patients had a lower incidence rate, higher mean age of onset, and higher hospitalization rate and experienced dyspnea, sore throat, and vomiting more often than croup patients. Our results may help in the differential diagnosis of croup and epiglottitis.

Abstract
BACKGROUND Corticosteroids, delivered systemically and by inhalation, are widely used for the treatment of multiple acute respiratory illnesses in children. However, the level of evidence to support the utility of this therapy varies between these different acute respiratory illnesses. OBJECTIVE To summarize the evidence regarding the utility of corticosteroids in the management of common acute pediatric respiratory conditions and to highlights the controversies regarding their use. METHODS Literature search of manuscripts describing the evidence regarding the efficacy of corticosteroids (systemic and inhaled) in the management of: acute asthma exacerbation among school age children, acute episodic wheeze among preschool children, viral croup, and acute viral bronchiolitis. RESULTS Current evidence indicates that systemic corticosteroids provide benefits for the treatment of acute asthma exacerbations in school age children, mainly in the acute care setting. In addition, high dose inhaled corticosteroid therapy administered in the Emergency Department appears to have comparable effect for the prevention of asthma-related hospital admission as systemic corticosteroids in this age group. In contrast, most available studies have not shown benefit for systemic corticosteroids during acute wheezing episodes in preschool children. Systemic corticosteroids decrease symptoms and the rate of hospital admissions in patients with severe croup; however, corticosteroids have no role in the treatment of acute bronchiolitis and their use in this condition should be discouraged. CONCLUSION Corticosteroids treatment response varies between the acute respiratory illnesses presented in this review. Future research should aim to fill the current gaps-of-knowledge regarding the utility this intervention such as the identification of specific wheezing phenotypes among preschool children which might benefit from systemic corticosteroids as a treatment for acute viral wheeze.

METHODS A retrospective, cross-sectional study of the National Hospital Ambulatory Medical Care Survey data between 1995 and 2009 of corticosteroid use at ED visits for asthma or croup was conducted. Odds ratios (OR) were calculated using logistic regression. Trends over time were compared using an interaction term between disease and year and were adjusted for all other covariates in the model. We included children aged 2 to 18 years with asthma who received albuterol and were triaged emergent/urgent. Children aged between 3 months to 6 years with croup were included. The main outcome measure was the administration of corticosteroids in the ED or as a prescription at the ED visit. RESULTS The corticosteroid use in asthma visits increased from 44% to 67% and from 32% to 56% for croup. After adjusting for patient and hospital factors, this trend was significant both for asthma (OR, 1.07; 95% confidence interval [CI], 1.04-1.10) and croup (OR, 1.07; 95% CI, 1.03-1.12). There was no statistical difference between the 2 trends (P = 0.69). Hospital location in a metropolitan statistical area was associated with increased corticosteroid use in asthma (OR, 1.76; 95% CI, 1.10-2.82). Factors including sex, ethnicity, insurance, or region of the country were not significantly associated with corticosteroid use. CONCLUSIONS During a 15-year period, knowledge transfer by passive diffusion or active guideline dissemination resulted in similar trends of corticosteroid use for the management of pediatric asthma and croup.

Abstract
Respiratory distress and stridor are common presenting symptoms for children in the emergency department. Most of these children will have common illnesses such as bronchiolitis or croup. Clinicians, however, must maintain a broad differential diagnosis and a healthy skepticism in the approach to each child's case so as not to miss uncommon or atypical presentations. We describe the case of a child with stridor in whom an airway hemangioma was ultimately diagnosed.

Abstract
This chapter provides the reader with a concise outline of the topics required for general pediatric board examination, respiratory component. Basic diagnostic testing is reviewed. Common upper airway problems, lower airway issues, and parenchymal diseases are covered. Congenital malformations and common diseases of the lung are reviewed. The physiology of extrapulmonary problems is reviewed. Sleep disordered breathing and the evaluation of apneas and ALTE/SIDS are also discussed. Hints regarding physiology, clinical features, diagnostic testing, and management are present with references to national guidelines and resources.
