[Recommendations for performing interventions during the COVID-19 pandemic].

Coronavirus infection (SARS-CoV-2), is a pandemic disease declared by the World Health Organization (WHO). This disease reports a high risk of contagion, especially by the transmission of aerosols in health care workers. In this scenario, aerosol exposure is increased in various procedures related to the airway, lungs, and pleural space.

Metastatic pulmonary calcification diagnosed by transbronchial cryobiopsy.

Metastatic pulmonary calcification is a rare disease characterized by calcium deposits in the lung. We describe a case where this pathology is observed associated with bone lithic lesions and kidney failure and it was diagnosed with transbronchial cryobiopsy.

Laryngeal stent for acute and chronic respiratory distress in seven dogs with laryngeal paralysis.

Background: Laryngeal paralysis, failure of arytenoid cartilage, and vocal fold abduction are commonly seen in older medium to large breed dogs. Observation of laryngeal function in dogs and cats is performed by transoral visualization. There are a variety of surgical techniques; aspiration pneumonia is the most common complication associated with surgical correction of laryngeal paralysis.

Bilateral lung disease, extensive and diffuse. Diagnosis of pulmonary alveolar proteinosis by bronchoscopic cryobiopsy.

Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the intra-alveolar accumulation of a proteinaceous phospholipid-laden material called surfactant. Clinically, this disease should be suspected with respiratory failure in association with a crazy paving pattern on high-resolution chest computed tomography. We report a 24-year-old gentleman who was referred to us for a history of respiratory failure, treatment with invasive ventilation and tracheostomy.
