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.

About one-third of the world population has latent TB infection (LTBI), the majority of which is distributed in 22 high-burden countries. Early diagnosis and treatment of active TB remains the top priority in resource-poor countries with high TB prevalence. Notwithstanding, because LTBI contributes significantly to the pool of active TB cases later on, its diagnosis and treatment is essential, especially in high-risk groups. ⋯ In addition, efforts should focus on airborne infection control measures in high-burden countries. A high prevalence of drug-resistant TB, the HIV epidemic, and delays in the diagnosis of active TB cases are other major concerns in areas of high TB prevalence. There is ample space for further research in these countries, whose outcomes may strengthen future national guidelines.
