Ventilator associated pneumonia (VAP) is the leading nosocomial infection in intensive care. It is associated with increased ICU and hospital stay, an increased use of antibiotics, and greater hospital costs. The recently launched Pneumonia Zero project (NZ) undoubtedly constitutes a challenge for professionals in the ICU, and has been designed to reduce the high incidence rates described. ⋯ The lack of a reference standard for the microbiological diagnosis of VAP has generated controversy over the diagnostic algorithms to be used, with the distinction of two strategies: a noninvasive or clinical strategy based on upper respiratory tract cultures, and an invasive method based on the use of quantitative cultures of samples from the lower respiratory tract obtained by bronchoscopic techniques. Despite the recommendations of scientific societies, which do not justify the use of qualitative tracheal aspirates in the microbiological diagnosis of VAP, this method is still routinely used. This study underscores the need to stop using qualitative tracheal aspirates as a routine diagnostic method for VAP, recommending the use of bronchoscopic techniques or quantitative tracheal aspirates.

Up to 60% of all children that receive to bone marrow transplantation (BMT) develop respiratory distress. It constitutes a common complication in this kind of patients, due to the increasing number of therapeutic applications of BMT and to improvement in the therapeutic approach to the problems associated with this procedure. We describe the different causes of respiratory distress after BMT in relation to its initiation or the presence of infection in its origin. The diagnosis and treatment are also reviewed.
