The gold standard for the histological diagnosis of interstitial lung diseases (ILD) is an open lung biopsy (OLB). Tissue samples obtained by forceps transbronchial lung biopsies (TBB) are usually too small. We aim to evaluate the efficacy and safety of cryo-TBB for the diagnosis of ILD and to explore its role as substitute for OLB. ⋯ Cryo-TBB is a safe and effective minimally invasive modality for the diagnosis of ILD. No OLB is needed in the majority of patients.

Meta Analysis
Comprehensive assessment of the long-term safety of pirfenidone in patients with idiopathic pulmonary fibrosis.
Pirfenidone is an oral antifibrotic agent that is approved in several countries for the treatment of idiopathic pulmonary fibrosis (IPF). We performed a comprehensive analysis of safety across four clinical trials evaluating pirfenidone in patients with IPF. ⋯ This comprehensive analysis of safety in a large cohort of IPF patients receiving pirfenidone for a total of 2059 PEY demonstrates that long-term treatment with pirfenidone is safe and generally well tolerated.

The respiratory health effects from tobacco smoking are well described. Cannabis smoke contains a similar profile of carcinogenic chemicals as tobacco smoke but is inhaled more deeply. ⋯ There is a need to integrate research on cannabis and respiratory health effects so that gaps in the literature can be identified and the more consistent findings can be consolidated with the purpose of educating smokers and health service providers. This review focuses on several aspects of respiratory health and cannabis use (as well as concurrent cannabis and tobacco use) and provides an update to (i) the pathophysiology; (ii) general respiratory health including symptoms of chronic bronchitis; and (iii) lung cancer.

The diagnosis of the peripheral lung lesion has been a long-standing clinical challenge--balancing accuracy with patient safety. With recent data revealing mortality benefits with lung cancer screening via low-dose computed tomography, now more than ever, clinicians will be challenged with the task of providing the means to provide a safe and minimally invasive method of obtaining accurate tissue diagnostics for the pulmonary nodule. In this review, we present available technologies to aid clinicians in attempts at minimally invasive techniques and the data supporting their use. In addition, we review novel tools under investigation that may further increase yield and provide additional benefit in obtaining an early diagnosis of lung cancer.
