Use of lung ultrasound in detection of complications of respiratory distress syndrome.

Repeated chest radiography is required for the diagnosis and follow-up of neonates with respiratory distress syndrome (RDS) and carries the risk of radiation hazards. Lung ultrasound (LUS) is a non-invasive bedside diagnostic tool that has proven to be effective in the diagnosis of RDS. Our aim was to assess the role of LUS with respect to the standard chest X-ray (CXR) in the detection of complications of RDS in neonates.

Relationship between angiotensin-converting enzyme gene polymorphism and respiratory distress syndrome in premature neonates.

Objective: The aim of this study was to investigate the possible relationship between angiotensin-converting enzyme (ACE) gene polymorphism (D/D and I/D genotypes) and respiratory distress syndrome (RDS) in preterm neonates.

Study Design: Our study included 120 preterm neonates (<37 weeks of gestation) with RDS (the patient group) and 120 preterm neonates without RDS (the control group). Blood samples were obtained from patients and control groups, and ACE gene polymorphism was analysed using the polymerase chain reaction method.
