Case ReportsConfirmed E-cigarette or vaping product use associated lung injury (EVALI) with lung biopsy; A case report and literature review.
E-cigarette or vaping has become an increasingly popular alternative to smoking tobacco. In September 2019 multiple cases of confirmed E-cigarette or vaping product use associated lung injury were published. However, there is limited knowledge regarding the pathologic mechanism of this condition. ⋯ The underlying pathophysiological mechanism in E-cigarette or vaping product use associated lung injury is most likely acute lung injury related to direct inhalant-mediated parenchymal inflammation.

Case ReportsSuccessful recovery from critical COVID-19 pneumonia with extracorporeal membrane oxygenation: A case report.
A public health emergency of current international concern is the outbreak of a severe respiratory illness, that is, coronavirus disease (COVID-19). The disease initially started in Wuhan, China, and it rapidly spread to most regions of the world. ⋯ We describe the patient's clinical course, from mild symptoms at the time of illness onset to symptoms of severe pneumonia as the illness progressed. We provide important information regarding our clinical experience for further understanding of management discrepancies, as treatment with extracorporeal membrane oxygenation or pharmacotherapy (e.g., antivirals, immunomodulators, and glucocorticoids) is often dependent on the severity of symptoms.

Case ReportsPulmonary cement embolism complicating percutaneous kyphoplasty: A case report.
Vertebral cement augmentation procedures, as kyphoplasty (KP) or percutaneous vertebroplasty (PVP), are commonly used for the management of pain of the vertebral column usually due to fractures related to traumatic injury, osteoporosis or metastatic lesion. It is a useful and safe technique with few complications. Among them, symptomatic pulmonary cement embolism (PCE) can happened, even rarely described in the literature, leading to severe cardio-respiratory manifestations depending on the location and size of the cement emboli. ⋯ In this case, the pulmonary cement embolism occurred after kyphoplasty, which is associated with less risk of PCE than vertebroplasty. The procedure was done under biplanar fluoroscopy and no leakage of cement was noted, which would raise suspicion for CPE. Repeat imagine after this procedure is not routinely done. This case demonstrates that systematic imaging post procedure should be considered.An anticoagulation with rivaroxaban seems to be effective in our patient.

Case ReportsA case of acute progressive diffuse interstitial lung disease preceding idiopathic multicentric Castleman disease.
It has been considered that idiopathic multicentric Castleman disease often involves pulmonary complications recognized as lymphocytic interstitial pneumonia. On the other hand, recent reports show that the computed tomography often show diffuse interstitial lung disease inconsistence with lymphocytic interstitial pneumonia. Pulmonary diseases with idiopathic multicentric Castleman disease are still rare and poorly understood. ⋯ Treatment with prednisolone improved the dyspnea, and the pulmonary lesions disappeared. The presented case suggests that interstitial lung disease could precede idiopathic multicentric Castleman disease. Chest physicians should be aware that idiopathic multicentric Castleman disease is one of the causative diseases of diffuse interstitial lung disease like non-specific interstitial pneumonia on the chest images.

Case ReportsRecurrence of emphysema post-lung transplantation in a patient with alpha 1 antitrypsin deficiency (AATD).
The genetic disorder alpha 1 antitrypsin deficiency (AATD) results in reduced levels of alpha 1 antitrypsin (AAT) in the lung and an imbalance between AAT anti-protease activity and the activity of proteases that degrade elastin and connective tissues. This imbalance commonly leads to the excessive proteolysis of structural tissue of the alveoli, causing chronic obstructive pulmonary disease (COPD)/emphysema. ⋯ Recurrence of COPD/emphysema was observed in a patient with AATD 2 years after initial successful lung transplantation and cessation of AAT therapy who recommenced smoking after no signs of disease at the 1-year assessment. This case demonstrates that smoking cessation is critical in patients with AATD, even after lung transplant, and it highlights that patients with AATD may benefit from AAT therapy post-lung transplant.
