[Hot topics in respiratory infections].

We review the most interesting articles on respiratory infections published in the last trimester of 2009 and in 2010. Notable publications in bronchiectasis were the Guidelines of the British Thoracic Society, as well as several articles on the natural course of the process, the impact of exacerbations on the course of the disease, and treatment with inhaled antibiotics. Other notable publications were the SEPAR-SEIMC consensus document for the management of tuberculosis and articles on the use of interferon-gamma in the diagnosis of tuberculosis infection. The new recommendations of the Spanish Society of Pneumology and Thoracic Surgery on community-acquired pneumonia have recently been published. Equally important are studies on the viral etiology of community-acquired pneumonia, the impact of corticosteroid treatment in pneumonia, the duration of antibiotic therapy and preventive measures in both community-acquired and nosocomial pneumonia.
