Mounier-Kuhn syndrome (MKS) is a congenital disorder characterized by tracheobronchomegaly resulting from the absence of elastic fibers in the trachea and main bronchi or atrophy and thinning of the smooth muscle layer. In this syndrome, dead space associated with tracheobronchomegaly increases and discharge of secretions decreases because of ineffective coughing. The most common complications are recurrent lower respiratory tract infections and bronchiectasis. We examined the clinical characteristics, radiological features, and related complications of patients with MKS. ⋯ In this article, 11 cases with various rarely seen complications are presented and evaluated in the light of current literature. We recommend that if chronic cough, recurrent pulmonary infections, and bronchiectasis seen in a patient, MKS should be kept in mind.

Comparative Study
Bench evaluation of commercially available and newly developed interfaces for mouthpiece ventilation.
Mouthpiece ventilation represents a valuable treatment for patients needing daytime non-invasive ventilation. This modality is however underused, in part because of limitations in the available equipment. ⋯ They found measurable differences in the ventilation's performances comparing the interfaces for mouthpiece ventilation, which seem to have a minor clinical relevance in the most settings, but should be systematically checked. They validated in-vitro the newly developed mouthpiece with respect to the ventilation performances; a clinical study is needed to investigate the potential advantages we expect from the new mouthpiece.

Observational Study
Clinical and hemodynamic characteristics of pulmonary hypertension associated with interstitial lung disease in China.
Pulmonary hypertension (PH) is an important complication of interstitial lung disease (ILD). The aim of the present study was to investigate characteristics and prognosis of ILD associated PH in a predominantly Chinese patient cohort. ⋯ Severe hemodynamic impairment along with PH can occur in patients with ILD. These patients have more severely impaired exercise capacity and cardiac function than ILD patients without PH. PVR was the only prognostic factor identified in this group of patients.

Review Meta Analysis
Risk factors for acute exacerbation of idiopathic pulmonary fibrosis: A systematic review and meta-analysis.
Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive fibrotic disease limited to the lungs. The course of disease varies widely, with some patients experiencing acute respiratory deterioration, a condition called acute exacerbations of IPF (AE-IPF). The risk factors contributing to AE-IPF are unclear. This systematic review and meta-analysis investigated the risk factors for AE-IPF. ⋯ Poor pulmonary function, mechanical procedures, higher serum KL-6 and secondary pulmonary hypertension were associated with increased risks of AE-IPF.

Randomized Controlled Trial Multicenter Study
Association of migraine with asthma risk: A retrospective population-based cohort study.
Both migraine and asthma are common health problems in the general population. However, the association between these two disorders is yet to be fully explored. ⋯ Adult patients with migraine are at a higher future risk of asthma development.
