ReviewThe use of indwelling pleural catheters for the treatment of malignant pleural effusions.
Introduction: The presence of a malignant pleural effusion (MPE) is a marker of advanced disease and associated with a poor prognosis. Patients are in a palliative stage of their disease and often suffer distressing symptoms including breathlessness and pain. Indwelling pleural catheters (IPCs) are effective in managing pleural effusions and allow ambulatory drainage of the pleural space, reducing symptoms associated with effusions and lowering overall hospital stay. ⋯ Recognition of the advantages and disadvantages of each approach allows a more informed patient choice. It is recognized that the use of IPCs can provoke pleurodesis, leading to removal of the catheter. For patients in whom prompt removal of the catheter is a priority, then a more aggressive drainage regime or instillation of talc via the IPC is a reasonable option.

ReviewCardiac sarcoidosis - an expert review for the chest physician.
Introduction: Sarcoidosis is a multisystem granulomatous disease predominantly affecting the lungs, with increased risk of cardiovascular disease, pulmonary hypertension and cardiac sarcoidosis (CS), the latter due to direct granuloma infiltration. Sarcoidosis is often managed by chest physicians who need to understand the diagnostic pathways and initial management plans for patients with cardiac involvement. Areas covered: The most serious consequence of CS is sudden cardiac death due to ventricular tachyarrhythmias or complete atrioventricular block. ⋯ Early immunosuppression reduces the risk of conduction abnormalities and incidence of supraventricular arrhythmias. Management of ventricular arrhythmias requires antiarrhythmic medications followed by possible catheter ablation and device (ICD) implantation. Expert commentary: Prospective trials are underway to identify the optimum methods for screening, which will guide future international statements on indications for and methods of screening in CS.

ReviewThe role of ultrasound lung artifacts in the diagnosis of respiratory diseases.
Thoracic ultrasound is employed for the diagnosis of many thoracic diseases and is an accepted detection tool of pleural effusions, atelectasis, pneumothorax, and pneumonia. However, the use of ultrasound for the evaluation of parenchymal lung disease, when the organ is still aerated, is a relatively new application. ⋯ Even though the practical role of lung ultrasound artifacts is accepted by many clinicians, their physical basis and the correlations between these signs and the causal pathology is not known in depth. Expert commentary: In this review, we discuss the meaning of A- and B-Lines in the diagnostic ultrasound imaging of the lung and the acoustic properties of the pleural plane which are at the basis of their generation.

ReviewThe burden of community-acquired bacterial pneumonia in the era of antibiotic resistance.
Community-acquired pneumonia (CAP) is a significant global health problem and leading cause of death and hospitalization in both the US and abroad. Increasing macrolide resistance among Streptococcus pneumoniae and other pathogens results in a greater disease burden, along with changing demographics and a higher preponderance of comorbid conditions. Areas covered: This review summarizes current data on the clinical and economic burden of CAP, with particular focus on community-acquired bacterial pneumonia (CABP). ⋯ Expert commentary: The clinical and economic burden of CABP is staggering, far-reaching, and expected to increase in the future as new antibiotic resistance mechanisms emerge and the world's population ages. Important measures must be initiated to stabilize and potentially decrease this burden. Urgent needs in CABP management include the development of new antimicrobials, adjuvant therapies, and rapid diagnostics.

ReviewBeclomethasone dipropionate, formoterol fumarate and glycopyrronium bromide as a combination therapy for chronic obstructive pulmonary disease.
The triple therapy term covers the combination of inhaled corticosteroid (ICS), long-acting β-receptor agonist (LABA) and long-acting anticholinergic drug (LAMA) in one or in separate inhalers. The latest GOLD 2018 (Global Initiative for Chronic Obstructive Disease) guidelines recommend the triple therapy in the management of chronic obstructive pulmonary disease (COPD) in patients of group D who despite the combination of two drugs: LAMA/LABA or ICS/LABA continue to have persistent symptoms or suffer from further frequent exacerbations. Areas covered: The first triple fixed-dose combination of extrafine beclomethasone/formoterol/glycopyrronium in one pMDI type inhaler intended for the treatment of COPD has been registered in Europe in 2017. ⋯ Expert commentary: A 20% reduction in the risk of moderate or severe exacerbation was found in patients receiving triple therapy compared to the ICS/LABA combination and LAMA monotherapy. Triple therapy reduces the number of exacerbations in comparison with double bronchodilatation (LABA/LAMA), thus representing an interesting therapeutic option in the management of COPD. The profile of side effects of triple therapy is typical for individual active agents included in the combination.
