The novel coronavirus disease 2019 (COVID-19) is spreading globally. Although its etiologic agent is discovered as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), there are many unsolved issues in COVID-19 and other infectious diseases. The causes of different clinical phenotypes and incubation periods among individuals, species specificity, and cytokine storm with lymphopenia as well as the mechanism of damage to organ...
Pulmonology
The past, present, and future of humidifier disinfectant-associated interstitial lung diseases in children

Exposure to environmental factors can cause interstitial lung diseases (ILDs); however, such types of ILDs are rare. From 2007 to 2011, an ILD epidemic occurred in South Korea owing to inhalational exposure to toxic chemicals in humidifier disinfectants (HDs). HD-associated ILDs (HD-ILDs) are characterized by rapidly progressing respiratory failure with pulmonary fibrosis and a high mortality rate of 43.8%−58.0%. Although...

Question: The immunogenicity and safety of GBP411 when administered to healthy infants are not understood.
Finding: The intergroup differences were not significant for all 12 serotypes after the booster dose. The overall incidence of solicited local adverse events between the groups did not differ significantly.
Meaning: GBP411 with a 2p+1 dosing schedule induced a substantial immune response, and may be safe for administration to healthy infants.

Clin Exp Pediatr. 2020;63(7):272-277.   Published online May 15, 2020
Background: The optimal management of perianal abscess in children is controversial.
Purpose: To evaluate the efficiency of conservative treatment of perianal abscess in children and identify parameters that predict therapy failure. Methods: All cases of children younger than 14 years of age with perianal abscesses between 2001–2016 were evaluated. Results: Of the 113 enrolled patients, 64 underwent subsequent surgery for advanced disease (primary...
