The current practice in the diagnostic work-up of patients with hemoptysis of unknown etiology: an international survey.

Background: Hemoptysis is a challenging and potentially life-threatening medical condition. The most appropriate diagnostic work-up is debated and several diagnostic approaches are implemented worldwide.

Methods: An international, online survey was carried out to investigate the current practice of the diagnostic work-up of patients with hemoptysis of unknown etiology.

The role of bronchoscopy in patients with SARS-CoV-2 pneumonia.

Background: The role of bronchoscopy in coronavirus disease 2019 (COVID-19) is a matter of debate.

Patients And Methods: This observational multicentre study aimed to analyse the prognostic impact of bronchoscopic findings in a consecutive cohort of patients with suspected or confirmed COVID-19. Patients were enrolled at 17 hospitals from February to June 2020.

Obstructive inflammatory tracheal pseudomembrane.

Pathologies acquired after the establishment of an artificial airway include stenosis, granulomas and the formation of pseudomembranes, to name a few. The most common form of presentation in adults is circumferential stenosis, which often requires therapeutic endoscopic measures to achieve resolution. This Case Report describes the case of an obstructive inflammatory tracheal pseudomembrane in the shape of a tracheal septum secondary to repeated intubations that was resolved with conservative treatment.

[Clinical relevance of distal airway involvement in asthma].

Asthma continues to be a global health problem, despite advances in diagnostic techniques and treatment. The inflammatory nature of asthma is currently indisputable, as is the involvement of the entire respiratory tree, both the proximal and most distal airways, which has been demonstrated in multiple studies. The development of the therapeutic arsenal, with more potent drugs and improved inhalation devices, has allowed a certain control to be maintained over the inflammatory process, although the inability to reach the most distal points of the airways has posed a stumbling block that seems difficult to overcome.

Bronchial thermoplasty in the treatment of asthma.

Despite the numerous guidelines and treatments available for asthma, the disease remains poorly controlled in some patients, who remain symptomatic, are a considerable burden on the health system, and account for most of the hospitalizations due to asthma. Bronchial thermoplasty is a novel experimental therapeutic option that consists of delivering radiofrequency-generated heat to the airways via a catheter inserted in the bronchial tree through a flexible bronchoscope to reduce smooth muscle quantity and contractility. The first investigations were conducted using an animal model.
