Chronic respiratory morbidity is a common adverse outcome of preterm birth, especially in infants who develop bronchopulmonary dysplasia (BPD), which is still a major cause of long-term lung dysfunction with a heavy burden on health care services and medical resources throughout childhood. The most severely affected patients remain symptomatic even in adulthood, and this may be influenced also by environmental variables (e.g. smoking), which can contribute to persistent obstruction of airflow. Of all obstructive lung diseases in humans, BPD has the earliest onset and probably lasts the longest...

Caffeine, a methylxanthine and nonspecific inhibitor of adenosine receptors, is an example of a drug that has been in use for more than 40 years. It is one of the most commonly prescribed drugs in neonatal medicine. However, until 2006, it had only a few relatively small and short-term studies supporting its use. It is thanks to the efforts of Barbara Schmidt and the Caffeine for Apnea of Prematurity (CAP) Trial Group that we now have high-quality and reliable data not only on short-term but also long-term outcomes of caffeine use for apnea of prematurity...

Oxygen is one of the most widely used drugs in the neonatal period. A lack of knowledge of oxygen metabolism and toxicity has prompted guidelines to fluctuate from liberal use to treat respiratory distress to restriction to avoid retinopathy of prematurity. In recent years, studies performed in the immediate postnatal period have revealed that newly born infants achieve a stable saturation only several minutes after birth. Moreover, the time needed to reach a saturation plateau is inversely proportional to a newborn's gestational age...

BACKGROUND: Lung ultrasound (LUS) is a promising technique for the diagnosis of neonatal respiratory diseases. Preliminary data has shown a good sensitivity and specificity of LUS in the diagnosis of respiratory distress syndrome (RDS) and transient tachypnea of the newborn (TTN). OBJECTIVE: The aim of this study was to calculate the sensitivity, specificity, and negative (NPV) and positive predictive value (PPV) of LUS for RDS and TTN, using an external reader blinded to the clinical condition...
