- Role of lung ultrasound patterns in monitoring coronavirus disease 2019 pneumonia and acute respiratory distress syndrome in children
- Satyabrata Roychowdhoury, Subhajit Bhakta, Manas Kumar Mahapatra, Saptarshi Ghosh, Sayantika Saha, Mithun Chandra Konar, Mihir Sarkar, Mousumi Nandi

Question: Potential role of patterns of lung ultrasonography (US) in monitoring changes in mechanically ventilated patients with coronavirus disease 2019 (COVID-19) pneumonia.
Finding: Interstitial syndrome, an irregular pleural line, and peripheral microconsolidation were the most prevalent findings. Changes in lung aeration after mechanical ventilation corelated with improved oxygenation. A fall in lung ultrasound reaeration score ≤ 5 may predict successful weaning.
Meaning: Lung US is gaining wider utility for monitoring COVID-19 pneumonia.

- The past, present, and future of humidifier disinfectant-associated interstitial lung diseases in children
- Eun Lee, So-Yeon Lee, Soo-Jong Hong

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...

-
Bronchopulmonary dysplasia (BPD) is a chronic lung disease of preterm infants with multiple factors affected from prenatal to postnatal periods. Despite significant advances in neonatal care over almost 50 years, BPD rates have not decreased; in fact, they may have even increased. Since more preterm infants, even at periviable gestational age, survive today, different stages of lung development affect the...

Asthma comprises a heterogeneous group of disorders characterized by airway inflammation, airway obstruction, and airway hyperresponsiveness (AHR). Airway inflammation, which induces AHR and recurrence of asthma, is the main pathophysiology of asthma. The fractional exhaled nitric oxide (FeNO) level is a noninvasive, reproducible measurement of eosinophilic airway inflammation that is easy to perform in young children. As airway inflammation precedes...

Recent progress in neonatal medicine has enabled survival of many extremely low-birth-weight infants. Prenatal steroids, surfactants, and non-invasive ventilation have helped reduce the incidence of the classical form of bronchopulmonary dysplasia characterized by marked fibrosis and emphysema. However, a new form of bronchopulmonary dysplasia marked by arrest of alveolarization remains a complication in the postnatal course of extremely low-birth-weight infants....
