Outcomes of Ultrasound-Guided Trigger Point Injection for Abdominal Wall Pain.

Background: Abdominal wall pain (AWP) is an important cause of chronic abdominal pain. History and physical examination are critical to the diagnosis of AWP. Trigger point injection (TPI) using either a steroid or a local anesthetic or a combination of both is often used to treat AWP.

Elevated laminin concentrations in lung secretions of preterm infants supported by mechanical ventilation are correlated with radiographic abnormalities.

Objective: The objective of this study was to test the hypothesis that the presence of laminin in neonatal tracheal aspirates would be indicative of damage to the structural integrity of the basal laminae of the lung caused by barotrauma and hyperoxia. We predicted that disruption of the basal laminae would be a critical determinant of lung injury and fibrotic repair in the preterm infant whose lungs were ventilated with supplemental oxygen.

Study Design: The study group consisted of 23 premature infants in the neonatal intensive care unit whose lungs were ventilated by supplemental oxygen.
