Case ReportsNegative pressure pulmonary edema related with severe sleep apnea syndrome: A case report.
Negative pressure pulmonary edema (NPPE) caused by airway obstruction was often life-threatening. Major cause of NPPE in adult patients was reported as post-operative laryngospasm. Therefore, NPPE was recognized widely among surgeons and anesthesiologist, but physicians also could face NPPE case in several clinical situation. ⋯ Therefore, we thought that the NPPE could be caused by severe SAS in this case. Continuous positive airway pressure therapy could improve this patient's symptoms promptly, and this patient could discharge without a complication. We should consider SAS as a cause of NPPE when examining NPPE patients especially with onset during sleep.

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 lymphocytic interstitial pneumonia presenting with a ground glass nodule as an initial finding.
A 65-year-old woman had a ground glass nodule, which was suspicious for lung cancer, in her right lung S6 by chest computed tomography. For diagnosis, video-assisted thoracoscopic surgery was performed, and the specimen showed a pathological pattern of lymphocytic interstitial pneumonia (LIP). ⋯ Subsequently, no other underlying diseases associated with LIP developed. The ground glass nodule was the initial lesion of LIP.

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.
