Diagnostic Usefulness of Computed Tomography Compared to Conventional Chest X-Ray for Chest Trauma Patients

PURPOSE: Early diagnosis and management of therapeutic interventions are very important in chest trauma. Conventional chest X-rays (CXR) and computed tomography (CT) are the diagnostic tools that can be quickly implemented for chest trauma patients in the emergency department. In this study, the usefulness of the CT as a diagnostic measurement was examined by analyzing the ability to detect thoracic injuries in trauma patients who had visited the emergency department and undergone CXR and CT. METHODS: This study involved 84 patients who had visited the emergency department due to chest trauma and who had undergone both CXR and CT during their diagnostic process. The patients' characteristics and early vital signs were examined through a retrospective analysis of their medical records, and the CXR and the CT saved in the Picture Archiving Communication System (PACS) were examined by a radiologist and an emergency physician to verify whether or not a lesion was present. RESULTS: Pneumothoraxes, hemothoraxes, pneumomediastina, pulmonary lacerations, rib fractures, vertebral fractures, chest wall contusions, and subcutaneous emphysema were prevalently found in a statistically meaningful way (p<0.05) on the CT. Even though their statistical significance couldn't be verified, other disorders, including aortic injury, were more prevalently found by CT than by CXR. CONCLUSION: CT implemented for chest trauma patients visiting the emergency department allowed disorders that couldn't be found on CXR to be verified, which helped us to could accurately evaluate patients.

A Case of Osteogenesis Imperfecta: Diagnosed in Uterus by Ultrasonogram / 대한산부인과학회잡지

Osteogenesis imperfecta is a relatively rare genetic condition of breakable bones with an incidence of 1 per 20,000~60,000. The clinical, genetic, and biochemical heterogeneity in osteogenesis imperfecta allows to least four subtypes to be distinguished. Prenatal diagnosis of osteogenesis imperfecta type II have been reported several times with ultrasonography. We recently experienced a case of osteogenesis imperfecta diagnosed in uterus by ultrasonogram and confirmed after termination and autopsy. We report here with a brief review of the literature.
