Bronchopulmonary dysplasia patients have preserved CT-measured central airway luminal area.
Bronchopulmonary dysplasia (BPD) is a condition of neonatal chronic lung disease due to disruption or dysregulation of pulmonary development. However, the pathophysiology of BPD in the larger conducting airways is not yet fully understood. The objective of our study was to determine if the area of the central airways are altered in patients with a history of BPD. ⋯ Airway luminal area was not different between BPD patients and matched controls for any of the measured airways (p > 0.05). Total lung volume detected in the CT scans was not different between BPD patients and matched controls (median [range]; 2775 [522-6215] vs 2969 [851-5612] cm3, p > 0.05). Our results suggest the luminal areas of the large conducting airways in patients with BPD are not different from matched controls.

Asthmatic smokers have reduced quality of life and need frequent specialist visits/hospitalization. Smoking habit represents for asthmatics a higher risk for comorbidities and lung function impairment. The impact of cigarette smoking on asthmatics should be addressed to evaluate the related risk factors. ⋯ Heavy smokers had more severe obstructive impairments than light and never smokers with similar ICS dose, showing a steroid insensitivity, but displayed less allergy with low FeNO and blood eosinophil count, thus being a definite phenotype.

An ongoing outbreak of coronavirus disease 2019 (COVID-19) has spread around the world. It is debatable whether asymptomatic COVID-19 virus carriers are contagious. We report here a case of the asymptomatic patient and present clinical characteristics of 455 contacts, which aims to study the infectivity of asymptomatic carriers. ⋯ In summary, all the 455 contacts were excluded from SARS-CoV-2 infection and we conclude that the infectivity of some asymptomatic SARS-CoV-2 carriers might be weak.

Extubation of patients with Coronavirus Disease 2019 (COVID-19) is a high risk procedure for both patients and staff. Shortages in personal protective equipment (PPE) and the high volume of contact staff have with COVID-19 patients has generated an interest in ways to reduce exposure that might be feasible especially during pandemic times and in resource limited healthcare settings. ⋯ We present a review of the current literature along with recommendations concerning safe extubation during the COVID-19 pandemic. In addition, a focused summary on the use of portable barrier hood devices, during the recent surge of COVID-19 is highlighted.

Multicenter StudyChest X-ray features of SARS-CoV-2 in the emergency department: a multicenter experience from northern Italian hospitals.
To evaluate the imaging features of routine admission chest X-ray in patients referred for novel Coronavirus 2019 infection. ⋯ The most common X-ray pattern is multifocal and peripheral, associated with interstitial and alveolar opacities. Chest X-ray, compared to CT, can be considered a reliable diagnostic tool, especially in the Emergency setting.
