Randomized Controlled Trial Comparative Study
Propofol versus midazolam in medical thoracoscopy: a randomized, noninferiority trial.
Hypoxemia is a surrogate marker for periprocedural endoscopic complications. There are no data comparing the safety of propofol sedation with another sedative regimen in medical thoracoscopy. ⋯ As assessed by the surrogate marker hypoxemia, propofol should not be considered the first choice for sedation in medical thoracoscopy.

Conventional transbronchial needle aspiration (TBNA) and endobronchial ultrasound (EBUS)-TBNA are widely accepted tools for the diagnosis and staging of lung cancer and the initial procedure of choice for staging. Obtaining adequate specimens is key to provide a specific histologic and molecular diagnosis of lung cancer. ⋯ The number of needle aspirations with both conventional TBNA and EBUS-TBNA was found to impact the diagnostic yield, with at least 3 passes needed for optimal performance. Neither needle gauge nor the use of miniforceps, the use of suction or the type of sedation/anesthesia has been found to improve the diagnostic yield for lung cancer. The use of rapid on-site cytology examination does not increase the diagnostic yield. Molecular analysis (i.e. EGFR, KRAS and ALK) can be routinely performed on the majority of cytological samples obtained by EBUS-TBNA and conventional TBNA. There does not appear to be a superior method for specimen preparation (i.e. slide staining, cell blocks or core tissue). It is likely that optimal specimen preparation may vary between institutions depending on the expertise of pathology colleagues.

Randomized Controlled Trial Multicenter Study
Cost-effectiveness of endobronchial valve therapy for severe emphysema: a model-based projection based on the VENT study.
Endobronchial valve (EBV) therapy is an innovative treatment that has been shown to be safe and effective in selected subgroups of patients with severe emphysema. ⋯ Our model-based analysis suggests that EBV therapy leads to clinically meaningful changes in disease staging and progression when compared to medical management, with resulting gains in unadjusted and quality-adjusted life expectancy. Our results indicate that EBV therapy is cost-effective in the German health-care system.

In the last decade, endobronchial ultrasound (EBUS) has evolved into an important tool for diagnostic bronchoscopy in daily practice. EBUS has established as a standard for the diagnosis of hilar or mediastinal lymphadenopathy, as a guidance technique for peripheral pulmonary lesions and for the evaluation of tumor involvement of the tracheobronchial wall or mediastinum. In the meantime, EBUS has also taken a significant role in mediastinal staging in lung cancer patients. However, EBUS plays not only a role in the diagnosis of malignancies, it is also important for the diagnosis of benign disorders.

Lung ultrasound (LUS) is an accurate tool for the diagnosis and follow-up of pneumonia in adults as well as in children. LUS is at least as accurate as chest radiography in diagnosing pneumonia. The most important parenchymal criterion is the positive air bronchogram within an echopoor area. ⋯ For further differential diagnosis, an integrated consideration of history, clinical examination, LUS and echocardiography should be performed. LUS is an excellent tool for IS screening. Repeated LUS control examinations may reflect the dynamics of IS under therapy and so LUS may serve as a therapy guide. .
