Emerging studies on radiologic findings in patients with coronavirus disease 2019 (COVID-19) report a high incidence of bilateral lung involvement, with ground-glass opacities imaging being the most common pattern on computed tomography. Cystic lesions, such as pneumatoceles, are rare, although they may occur in 10% of cases. Cyst formation may be explained by a focal pulmonary trauma caused by mechanical ventilation or infection-related damage to the alveolar walls leading to pneumatoceles. The superinfection of pneumatoceles is a potential life-threatening condition for which no standardized therapeutic algorithm has been accepted. We report a case of a COVID-19 patient successfully treated by lung resections for infected pneumatoceles., (Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Objective: To report data about "real-life" treatments with non-invasive ventilation for acute respiratory failure (ARF), managed outside intensive care units by anaesthesiologists acting as a medical emergency team., Design: Observational study; prospectively collected data over a 6-month period in a single centre., Setting: Non-intensive wards in a University Hospital with 1,100 beds., Patients: Consecutive patients with ARF for whom a ventilatory support was indicated but tracheal intubation was not appropriated or immediately needed., Interventions: None., Measurements and Results: Patient's characteristics, safety data, short-term outcome and organizational aspects of 129 consecutive treatments were collected. The overall success rate was 77.5%, while 10.1% were intubated and 12.4% died (all of them were "do not attempt resuscitation" patients). The incidence of treatment failure varied greatly among different diseases. Complications were limited to nasal decubitus (5%), failure to accomplish the prescribed ventilatory program (12%), malfunction of the ventilator (2%) and excessive air leaks from face mask (2%) with no consequences for patients. Three patients became intolerant to NIV. The work-load for the MET was high but sustainable: on average NIV was applied to a new case every 34 h and more than three patients were simultaneously treated., Conclusions: Under the supervision of a MET, in our institution NIV could be applied in a wide variety of settings, outside the ICU, with a high success rate and with few complications.

Retinoic acid syndrome is a potentially life-threatening complication of therapy for acute promyelocytic leukemia (APL) with all-transretinoic acid (ATRA). The case of a 55-year old male patient admitted to the hospital because of a bleeding diathesis is reported. APL was diagnosed and he underwent treatment with idarubicin and ATRA (GIMEMA protocol); 24 hrs after ATRA treatment he developed retinoic acid syndrome and was admitted to the Intensive Care Unit because of severe respiratory insufficiency (dyspnoea, tachypnea and severe hypoxemia (SpO2 75%). Pulmonary insufficiency was treated non-invasively with CPAP and the patient recovered from pulmonary distress one week later.
