Lipid peroxidation products as predictors of oxidant-mediated disease in preterm infants.

Background: Preterm infants are susceptible to "oxygen radical diseases" (ORD). 8-isoprostane (8-IP) is a bioactive eicosanoid generated by reactive oxygen species-catalyzed peroxidation of arachidonic acid. Malondialdehyde (MDA) is generated by the decomposition of oxidant-induced lipid hydroperoxides.

International Expert Consensus and Recommendations for Neonatal Pneumothorax Ultrasound Diagnosis and Ultrasound-guided Thoracentesis Procedure.

Pneumothorax (PTX) represents accumulation of the air in the pleural space. A large or tension pneumothorax can collapse the lung and cause hemodynamic compromise, a life-threatening disorder. Traditionally, neonatal pneumothorax diagnosis has been based on clinical images, auscultation, transillumination, and chest X-ray findings.
