The lung volume reduction coil (LVR-coil), a new experimental device to achieve lung volume reduction by bronchoscopy in patients with severe emphysema, works in a manner unaffected by collateral airflow. We investigated the safety and efficacy of LVR-coil treatment in patients with heterogeneous emphysema. ⋯ LVR-coil treatment is a promising technique for the treatment of patients with severe heterogeneous emphysema. The treatment is technically feasible and results in significant improvements in pulmonary function, exercise capacity, and quality of life, with an acceptable safety profile.

Comparative Study
Usefulness of preemptive anticoagulation in patients with suspected pulmonary embolism: a decision analysis.
The diagnostic workup of pulmonary embolism (PE) may take several hours. The usefulness of anticoagulant treatment while awaiting the results of diagnostic tests has not been assessed. The objective of this study was to compare the risks and benefits of bid low-molecular-weight heparin vs no treatment in patients with suspected PE. ⋯ Our model suggests that patients with intermediate and high/likely probabilities of PE benefit from preemptive anticoagulation. With a low probability, the decision to treat may rely on the expected diagnostic delay.

Case Reports
IgG4-related systemic disease presenting with lung entrapment and constrictive pericarditis.
We describe a 29-year-old woman who presented with chronic pleuropericarditis complicated by lung entrapment and constrictive pericarditis. Pleural biopsy performed during the decortication procedure revealed fibrinous pleuritis with lymphoplasmacytic inflammation including IgG4-positive plasma cells. The patient responded favorably to corticosteroid therapy with resolution of pleural effusion and constrictive physiology. To our knowledge, this is the first reported case of IgG4-related systemic disease manifesting as lung entrapment and constrictive pericarditis.

Pulmonary rehabilitation (PR) is an evidence-based, multidisciplinary, comprehensive intervention that can be integrated into the management of individuals with chronic lung disease. It aims to reduce symptoms, optimize function, increase participation in daily life, and reduce health-care resource utilization. ⋯ Issues related to exercise training focus on strategies to optimize the training load. We also comment on the acquisition of self-management skills, balance training, optimizing access, and maintaining gains following completion of PR.

Few studies have examined common childhood infections and adult asthma. We examined associations between childhood infectious diseases, childhood pneumonia, and current, persisting, and incident asthma to middle age. ⋯ Overall, childhood infectious diseases protected against asthma persisting in later life, but pertussis and measles were associated with new-onset asthma after childhood. Measles and pertussis immunization might lead to a reduction in incident asthma in later life.
