RESUMO
BACKGROUND: Nontuberculous mycobacteria (NTM) are pathogens that commonly affect the paediatric population and its most frequent manifestation is a cervicofacial lymphadenopathy. With the improvement of technologies, new species have been recently identified. CASE PRESENTATION: We report the first case of NMT lymphadenitis in a child caused by Mycobacterium marseillense, a newly described species belonging to Mycobacterium avium complex. CONCLUSIONS: Improving the identification of these newly discovered mycobacteria, further information will be available about their clinical involvement and their best treatment.

Lung debris in respiratory distress syndrome (RDS) and meconium aspiration syndrome (MAS) contribute to deteriorate pulmonary function. Surfactant lavage, also with minimal quantity of diluted surfactant, is an effective method for treatment of severe MAS and seems to be useful also in course of RDS evolving to chronic lung disease (CLD), by improving lung mechanics. Authors report a clinical study in which tracheobronchial lavage with surfactant (15 ml/Kg of diluted porcine surfactant) improved significantly lung function in 3 patients with RDS in prolonged mechanical ventilation and in 2 patients with MAS.

Chronic Lung Disease (CLD) remains a major complication of prematurity, and barovolutrauma is thought to be one of the most important predisposing factors. In view of reducing the damage due to variability of tidal volume (Vt), we studied the application of the new option of volume guarantee (VG). We analyzed ventilatory data of 25 preterm infants with respiratory distress syndrome (RDS) in two situations: pressure support ventilation (PSV) + VG vs PSV alone. Data collected showed application of significantly lower peak inspiratory pressure (p < 0.001) and mean airway pressure (p < 0.001) with the constant Vt. We conclude that this ventilatory strategy, by reducing the barotrauma, could be considered a protective ventilation.
