PURPOSE: This study was designed to evaluate diagnostic accuracy of serial electrocardiograms(ECG), myocardial band of creatinine phosphokinase(CK)(CK-MB/CK ratio) and two dimensional echocardiography(ECHO) for myocardial injury in patients with blunt chest trauma. METHODS: We prospectively investigated 54 patients(male : 38, female : 16, mean age : 41) with severe blunt chest trauma. Presence of myocardial injury was determined by increase(>0.1ug/L) of peak serum troponin T(TnT) concentration from serial mesurements. RESULTS: Among 54 patients with blunt chest trauma, 23 patients(43%) had increased peak TnT level which suggested of myocardial injury. Among 23 patients with increased TnT, abnormal ECG findings were found in 18(78%) and echocardiographic abnormalities were observed in 17(74%). Cardiovascular events in 9(39%) of 23 patients with increase Tnt. There was no cardiovascular events in patients with normal TnT. CONCLUSION: Significant proprotion of patients with blunt chest trauma had elevated TnT value which suggested of myocardial injury. We recommend echocardiagraphy and serial tracing of ECG to verify the clinical significance of elevated TnT in patients with blunt chest trauma.

PURPOSE: Breast conserving surgery is increasingly performed in early stage breast cancer patients. A certain propotion of these patients are at substantial risk for systemic metastasis. However, there is no valid consensus about optimal sequencing of chemotherapy and radiation therapy. METHODS: We conducted a randomized prospective study to investigate whether concurrent chemotherapy and radiation therapy after breast conserving surgery are associated with increased toxicity. Fifty-seven patients with stage I or II breast cancer were randomly assigned to receive CMF chemotherpy either simultaneously with (n=37) or before (n=20) radiation therapy. RESULTS: Moist desquamation was the most common adverse effect which occurred in 46% (16/37) of the patients treated with concurrent chemotherapy and radiation therapy and 40% (8/20) of those treated with the sequential regimen. This difference between two groups was not statistically significant. Also the incidence of severe neutropenia (WBC<1,800) or abnormal elevation of liver enzymes was not influenced by the sequencing of the adjuvant therapies. Arm edema was observed in 2 patients of the concurrent group and in 2 patients of the sequential regimen. Two patients treated with the concurrent regimen did not complete 6 cycles of chemotherapy while only one patient treated with sequential regimen did not. The incidence of toxicity during chemotherapy was not altered by the timing of radiation therapy. CONCLUSION: Chemotherapy and radiation therapy can be given concurrently after breast conserving surgery in stage I or II breast cancer patients without increase in serious toxicity.

BACKGROUND: In korea, significant proportion of victims with out-of-hospital cardiac arrest have no change to survive because some physicians regard the victim with cardiac arrest outside the hospital as the dead and they do not attempt cardiopulmonary resuscitation(CPR). And we cannot expect bystander-initiated CPR and emergency medical system in resuscitating the victims with cardiac arrest. We studies the outcome of resuscitation attempts and the factor associated with survival in patients with out-of-hospital cardiac arrest in current situation of emegency medical system. Method: We attempted cardiopulmonary resuscitation(by standard guidelines) in 74 consecutive victims with non-traumatic out-of-hospital cardiac arrest in emergency department. RESULTS: Of 74 victims with cardiac arrest 35(47%) had no any restoration of spotaneous circulation(ROSC), 26(35%) had transient ROSC but died within 24 hours,6(8%) survived over 24 hours but died in the hospital, and 7(10%) discharged alive. Factors associated with survival were cardiac origin as a cause of cardiac arrest, ventricular fibrillation as a initial ECG rhythm, and short circulatory arrest time. CONCLUSION: Survival rate of victims with non-traumatic out-of-hospital cardiac arrest was 10%. Considering the feasibility to survive, CPR should be attempted in patients with out-of-hospital cardiac arrest if do-no-resusciate(DNR) is not indicated.

PURPOSE: The purposes of this investigation were to discover the possibility of clinical application in the areas of dental implants and bone grafts by investigating the bone formation histologically around specimen which was depending on the intensity of magnetic field of neodymium magnet inside of the specimens. MATERIAL AND METHOD: 1. Measurement of magnetic intensity - placed the magnet inside of the specimen, and measured the intensity of magnetic field around the 1st thread and 3rd thread of specimen 20 times by using a Gaussmeter(Kanetec Co., Japan). 2. Surgical Procedure - Male rabbit was anesthetised by constant amount of Ketamine (0.25ml/kg) and Rompun (0.25ml/kg). After incising the flat part of tibia, and planted the specimens of titanium implant, control group was stitched without magnet, while experimental groups were placed a magnedisc 500(Aichi Steel Co., Japan) or magnedisc 800(Aichi Steel Co., Japan) into it, fixed by pattern resin and stitched. 3. Management after the surgery. - In order to prevent it from the infection of bacteria and for antiinflammation, Gentamycin and Ketopro were injected during 1 week from operation day, and dressed with potadine. 4. Preparation of histomorphometric analysis - At 2, 4 and 8 weeks after the surgery, the animals were sacrificed by excessed Ketamine, and then, specimens were obtained including the operated part and some parts of tibia, and fixed it to 10% of PBS buffer solution. After embedding specimens in Technovit 1200 and B.P solution, made a H-E stain. Samples width was 75micrometer. In histological findings through the optical microscope and using Kappa image base program(Olympus Co. Japan), the bone contact ratio and bone area ratio of each parts of specimens were measured and analyzed. 5. Statistical analysis Statistical analysis was accomplished with Mann Whitney U-test. RESULTS AND CONCLUSION: 1. In histomorphometricl findings, increased new bone formation was shown in both control and experimental groups through the experiment performed for 2, 4, and 8 weeks. After 4 weeks, more osteoblasts and osteoclasts with significant bone remodeling were shown in experimental groups. 2. In histomorphometric analysis, the bone contact ratios were 38.5% for experimental group 1, 29.5% for experimental group 2 and 11.9% for control group. Experimental groups were higher than control group(p<0.05)(Fig. 6, Table IV). The bone area ratios were 60.9% for experimental group 2, 46.4% for experimental group 1 and 36.0 % for control group. There was no significantly ststistical difference between experimental groups and control group(p<0.05)(Fig. 8, Table VII) 3. In comparision of the bone contact ratios at each measurement sites according to magnetic ntensity, experimental group 2(5.6mT) was higher than control group at the 1st thread (p<0.05) and experimental group 1(1.8mT) was higher than control group at the 3rd thread(p<0.05)(Fig. 7, Table V, VI). 4. In comparision of the bone area ratios at each measurement sites according to magnetic intensity, experimental group 2(5.6mT) was higher than control group and experimental group 1(4.0mT) at the 1st thread(p<0.1) and experimental group 2(4.4mT) was higher than experimental group 1(1.8mT) at the 3rd thread(p<0.1)(Fig. 9, Table IX, X). Experiment group 2 was largest, followed by experiment group1 and control group at the 3rd thread of implant. There was a significant difference at the 1st thread of control group and experiment group 2. and at 1st thread and 3rd thread of experiment group 1 and 2, and not at control group experiment group 1.(p<0.1)

Not infrequently, we meet urgent situations that emergency cardiac pacing is inevitable. Paricularly, in patients with impending brady-asystole cardiac arrest, we cannot but introduce pacing cartheter without fluroscopic guidance in emergency department if transcutaneous pacing is not available. There is little report about emergency transvenous cardiac pacing without fluoroscopic guidance in patients with impending cardiac arrest in korea. We report our experiences of temporary transvenous pacing by blind approach performed in patients with impending bradyasystolic cardiac arrest in emergency department. Among 10 patients who blind pacing were performed. 7 were successfully paced and 3 were not. 5 of 7 patients with successful pacing died of underlying diseases. 2 patients wiere alive. A hematoma around the puncture site was developed in a patient receiving thrombolytic therapy. We concluded that temporary transvenous pacing withoup fluoroscopy should be tried in the emergency situations if fluoroscopy or transcutaneous pacemaker is not avialable.
