The purpose of this study was to compare the fitness of the IPS Empress ceramic crowns according to margin type such as bevel, shoulder, rounded shoulder, shoulder with bevel, rounded shoulder with bevel and grooved bevel. After 10 experimental dies were constructed for each group, the IPS Empress ceramic crowns were fabricated on the dies, cemented with resin cement(Bistite resin cement, Tokuyama Soda Co. Ltd., Japan) and embeded in clear epoxy resin. Each specimen was sectioned with a low speed diamond saw in both the faciopalatal and the mesiodistal direction. The cement film thickness was measured with a measuring microscope. The obtained results were as follows : 1. The fitness at the external margin was good in the following order: rounded shoulder(28.99), shoulder with bevel(31.33), grooved bevel(31.79), rounded shoulder with bevel(34.65), bevel(35.02) and shoulder(35.08). However there is no significant statistical difference. 2. The fitness at the internal margin of bevel(25.75), rounded shoulder(31.24), shoulder with bevel(32.07) and rounded shoulder with bevel(34.45) was better than that of shoulder(47.98). 3. The fitness at the axial surface of bevel(26.58) was better than that of shoulder(49.59). 4. The fitness at the central fossa was good in the following order: shoulder with bevel(38.88), grooved bevel(40.46) rounded shoulder with shoulder(46.29), shoulder(48.91), bevel(49.47) and rounded bevel(52.07). However there is no significant statistical difference. 5. Overall fitness of bevel(29.71), rounded shoulder(32.49) and shoulder with bevel(34.47) was better than that of shoulder(44.73).

PURPOSE: The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conducted to ascertain CT finding of small bowel rupture result from abdominal trauma. MATERIALS AND METHODS: A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. RESULTS: Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of the bowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal or retroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collection was seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12 cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases, respectively. CONCLUSION: The CT scan is sensitive and effective modality for evaluation of small bowel rupture after abdominal trauma, because of high detectability of diagnostic and suggestive CT findings.

BACKGROUND: The mechanically ventilated patient's stay in the emergency department (ED) is brief but ventilatory management and intervention must be optimal. Agitation, anxiety, distress, and discomfort are common complications far the ventilated patient. So, sedation is necessary to reduce these complications. METHODS: Patients were monitored and mechanically ventilated. Midazolam was intravenously administered as loading dose(3-5mg), followed by continuous infusion at a rate of 0.06mg/kg/hr, titrated to achieve a predetermined sedation level (Ramsay's sedation score: 2-5 points, Glasgow coma score scathe : 8-11 points). RESULTS: After onset of predetermined sedation, systolic and diastolic blood pressure and heart rate remained stable during continuous infusion when compared with those of the initial state. Arterial blood gas and peak inspiratory pressure remained unchanged but respiratory rate was decreased to allowable ranges. CONCLUSION: A short-term continuous infusion of midazolam was a safe and erective method for sedation of ventilated patients in ED.
