Radiological considerations of posterior cervical lateral mass fixation using plate and screw.
The aim of this study is to determine whether the posterior cervical fusion methods with the plate-screw system applied to the lateral mass of cervical spine are radiologically safe to patients. The lateral cervical X-rays and CT scans were done on 40 normal adults without cervical problem. Based on Roy-Camille and Magerl's method, the theological trajectory of screw was shown on films and the parameters were measured. ⋯ A reduced lateral angle of screw (19.6 +/- 3.5 degrees C) performed with the concept based on Magerl's method resulted a longer depth of screw (13.5 +/- 2.1 mm). Both Roy-Camille and Magerl's methods seemed to be radiologically safe to normal persons. However, the authors recommend the reduced lateral angle (19.6 +/- 3.5 degrees C) of screw based on the Magerl's method more than an original Magerl's methods.

Case ReportsPerimortem cesarean delivery following severe maternal penetrating injury.
The case of a severely traumatized pregnant patient, in whom a perimortem cesarean section, in the emergency department, led to the birth of a viable baby, with long-term survivor, is described. A postmortem cesarean section, resulting in fetal survival, performed after 45 minutes of maternal cardiopulmonary resuscitation is reported in a patient with multiple penetrating injuries. A 27-year-old primigravida suffered cardiopulmonary arrest at the 34th week of gestation following multiple knife injuries. ⋯ A low segment cesarean delivery was performed, and a female baby was delivered. The time interval between cardiopulmonary arrest and delivery, prior maternal health status, and continued cardiopulmonary resuscitation are important determinants of fetal survival. A perimortem cesarean section is advised in case of multiple penetrating injuries, even after 45 minutes of cardiopulmonary resuscitation, since it may result in fetal salvage.

A traumatic abdominal wall hernia (TAWH) is a rare type of hernia, which follows blunt trauma to the abdomen, where disruption of the musculature and fascia occurs, with the overlying skin remaining intact. The case of a sixty five year old female that developed a TAWH, following the collapse of the roof of her house, is reported. She underwent a laparotomy for suspected liver injury, followed by repair of the hernia using a fascia lata graft taken from the thigh. The etiology, pathogenesis and management of this rare hernia are discussed.

Clinical and echocardiographic characteristics of pericardial effusion in patients who underwent echocardiographically guided pericardiocentesis: Yonsei Cardiovascular Center experience, 1993-2003.
Percutaneous pericardiocentesis guided by two-dimensional echocardiography was introduced in 1983 as an alternative to electrocardiographically or fluoroscopically guided puncture for the management of pericardial effusion. The objective of this study was to investigate echocardiographically (echo)- guided pericardiocenteses performed at Yonsei Cardiovascular Center from January 1, 1993 to December 31, 2003, and also to determine whether patient profiles, etiology, and practice patterns have changed over this 11-year period. The medical records of 272 patients were examined and a follow-up survey was conducted. ⋯ Malignancy was the leading cause of a pericardial effusion requiring pericardiocentesis (45.6%). The incidence of pericardial effusion following cardiothoracic surgery and percutaneous coronary intervention procedures accounted for nearly 20% of all pericardiocenteses performed. Echo-guided pericardiocentesis has become a safe, standard practice for clinically significant pericardial effusion, in line with the changes of patients profiles over the 11 years of the study.

Case ReportsA case of pulmonary artery intimal sarcoma diagnosed with multislice CT scan with 3D reconstruction.
Pulmonary artery intimal sarcoma is a rare highly lethal disease, with additional retrograde extension to pulmonic valve and right ventricle being an extremely rare condition. It is frequently mistaken for pulmonary thromboembolism. ⋯ After excision of the mass, the patient's condition improved dramatically, and the pathologic findings revealed pulmonary intimal sarcoma. This report emphasizes that helical chest CT with 3D reconstruction can be an important tool to differentiate the characteristics of pulmonary artery lesions, such as intimal sarcoma and thromboembolism.
