Question: The clinical differences between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and human coronaviruses (HCoV) in children remain unknown.
Finding: This study compared the clinical findings of children infected with SARS-CoV-2 versus HCoV. Its findings suggest that children and adolescents with SARS-CoV-2 have a milder clinical course than those with HCoV.
Meaning: The clinical course of children and adolescents with SARS-CoV-2 should be closely monitored during the coronavirus disease 2019 pandemic.

Methods: We retrospectively analyzed data of children younger than 18 years diagnosed with pneumonia at 117 Emergency Departments in Korea between 2007 and 2014. Results: Over the study period, 329,380 pediatric cases of pneumonia were identified. The most frequent age group was...

Clin Exp Pediatr. 2015;58(10):380-385.   Published online October 21, 2015
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.

Sun-Mee Choi, Kyung-Yil Lee, Hyung-Shin Lee, Ja-Hyun Hong, Mi-Hee Lee, Byung-Churl Lee
Clin Exp Pediatr. 2005;48(1):101-103.   Published online January 15, 2005
Meningococcal disease is not rarely associated with abnormalities of the complement system. We experienced a case of C9 deficiency with meningococcal meningitis from a 12-year-old girl. Identification of complement deficiency has implications for management, including family studies, prophylaxis, vaccination, and altered threshold for infection screening and treatment.
