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 ${\leq}18years$ 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 $2.2{\pm}2.0$ and $5.6{\pm}5.8years$, 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.

Background and Objectives Scope classification is designed to classify acute epiglottitis according to laryngoscopic findings. There is no report about the utility of classification; the difference between the diagnosis and the prognosis by the Scope classification was not found. The aim of this study was to evaluate the utility of Scope classification in patients with acute epiglottitis. Subject and Method 127 patients who had been admitted to our hospital were diagnosed with acute epiglottitis. The patients were classified by the Scope classification. We compared demographic characteristics, clinical symptoms and signs, laboratory findings, and clinical course among the patient groups and divided the results according to the Scope classification. Results There are no significant differences among the groups in demographic characteristics, clinical symptoms and signs, laboratory findings, and clinical course. Conclusion The Scope classification of acute epiglottitis does not seem to be a method to evaluate the severity of acute epiglottitis. Thus, we need to develop multidisciplinary approaches for acute epiglottitis.

Backgraound and Objectives : The voice change can occur in acute epiglottitis or peritonsillar abscess, and the labelings of both changes as a "muffled voice" or "hot potato voice", The aim of this study was to investigate the difference of changes in acoustic feature of voice before and after treatment in patients with acute epiglottitis or peritonsillar abscess. Subjects and Method: 13 patients with acute epiglottitis and 12 patients with peritonsillar abscess were enrolled in the study. Acoustic analysis on sustained Korean vowels /${\alpha}$/, /u/ and /i/ were performed before and after treatment. Results: In patients with acute epiglottitis, the first formant frequency (F1) of /${\alpha}$/ was increased, and the second frequency (F2) of /i/ was decreased. In patients with peritonsillar abscess, F1 and F2 of /${\alpha}$/ were decreased. F1 of /i/ and /u/ were increased, while F2 were decreased. Conclusion : The anatomical and functional changes of oropharynx and larynx by acute epiglottitis and peritonsillar abscess can cause different change in resonance and speech quality. We suggest that these changes could be the cause of 'muffled vocie' in patients of acute epiglottitis or peritonsillar abscess, but different characteristics of phonation in each disease should be distinguished.

Acute epiglottitis is one of the common conditions of upper airway obstructions in children. The clinical course is not only fulminant but possibly fatal, resulting from massive swelling of supraglottic structures especially epiglottis caused by Hemophilus influenzae. This is so because early recognition and careful airway management is always desired. Numerous reports in the literature reveals that a majority of cases occurs mainly in young children under six years of age, however, recent reports of acute epiglottitis in adult is increasing. We present a series of acute epiglottitis in adult and a review of the literature. We also discuss the differences between acute epiglottitis in adult and in children in terms of clinical course, causative organism, management and the results of treatment.

Acute epiglottitis is a life threatening inflammatory. disease of the upper airway mainly in children, however, the recent reports about acute epiglottitis in adults are increasing. The common symptoms are sore throat, dysphagia, dyspnea and salivary drooling. As the laryngeal edema progresses, the patient sits up, leans forward, with the chin thrust forward, having obvious difficulty breathing. Early recognition and proper airway maintenance until the inflammatory edema subsides are essential steps to avoid a possible life threatening upper airway obstruction. We experienced two cases of acute epiglottitis with sitting up position, chin thrust forward, having dyspnea.

Laryngeal tuberculosis is very rare, but the most common sites of laryngeal lesions include true vocal cords and false vocal cords. The major symptoms of laryngeal tuberculosis are hoarseness, dysphagia, and cough. Epiglottic tuberculosis has rarely been reported. We experienced one case of epiglottic tuberculosis that presented as acute epiglottitis and report it with reviews of literature.

Acute supraglottitis is characterized by an inflammation and edema of the supraglottic region and a potential life-threatening condition because of its risk for sudden upper airway compromise. Prompt diagnosis, administration of broad spectrum antibiotics, and airway management is pivotal for reducing serious complications. In the immunocompromised host, microorganisms are more likely to elicit mucosal inflammations, thus clinicians should pay attention to those patients for prompt removal of the causes of immune disruption. Here we report a case of acute adult supraglottitis with neutropenia caused by anti-thyroid drug with a review of the related literatures.

Among the various emergency diseases in children, acute pulmonary and airway disease are common clinical conditions encountered by radiologists, and the first imaging modality is chest radiography. Therefore, it is important to be familiar with these diseases and their imaging findings. In this article, we review pneumonia and mimickers of acute pulmonary disease. For acute airway disease, we reviewed croup, acute epiglottitis, tracheomalacia, asthma, postinfectious bronchiolitis obliterans, and foreign body aspiration. We hope this review of special diseases can help the diagnosis and treatment in children.
