BACKGROUND: Recently, the incidence of acute myocardial infaction has been gradually increasing as prolongation of life spans and improvements of diet and life styles in Korea. The rate of mortality and sudden death is higher than other diseases. The purpose of this study is to evaluate factors which can affect on the mortality of AMI during initial 24 hrs. METHODS: A retrospective clinical study was done on 364 consecutive patients with AMI who had been presented to Keimyung University Dong-sang Medical Center from January 1990 to May 1997(M:F ratio=254:110). The subjects were divided two groups. The Group I was patients who had expired during the initial 24hrs period of AMI(47 patients, 13%), the Group II was patients who had survived(317 patients, 87%). We compared clinical features, EKG, laboratory results in both groups and tried to analyse the vulnarable factors. RESULTS: The results were as follows; 1) The mean age in Group I (64.4 yearly) was older than in Group II(61.3 yearly) and female gender was also higher in Group I. The mean systolic/diastolic blood pressures of the Group I(103/61mmHg) were lower than those of the Group II(123/75mmHg). 2) The chest pain and mental change were noted more frequently in Group I than in Group II and the dyspnea was less frequent in Group I than Group II. 3) The higher grades of Killip classification was significantly more frequent in Group I than in Group II. 4) The mean onset to drug time for thrombolytics in Group I and Group II were 14.1 hrs and 6.6 hrs. 5) The mortality rate of the Group I and the Group II were respectively 13%, 6.6%. The most common causes of death were cardiogenic shock and ventricular arrhythmia. CONCLUSION: The mortality rate of initial 24 hrs of onset as form of sudden death was higher than post-24hrs group(66.2%). The factors for the higher mortality group were old age and female gender, and they were unstable in vital signs, higher Killip classifications. Therefore, these groups demand more rapid and aggressive approach than the other groups.

In general, pelvic fracture carries higher mortality especially from motor veicle accident, we have retrospectively reviewed charts and radiographs of 185 patients in order to identify clinical fading, kinds of fracture, hemodynamic changes and associated injuries in patients with pelvic fractures. We attempted to classify pelvic fractures according Young classification. The following results were obtained; 1. On age and sex distribution, the pelvic fractures showed peak incidence between 2nd decade and 5th decade. Male was affected more frequently than female, the ratio being male to female, 2.6 to 1. 2. The mechamisn of injury was motor veicle accident in 155(83.8%), fall in 25(13.5%), others in 5(2.7%). 3. The associated injuries of pelvic fractures: extremity, thoracic, urinary system, intraperitoneal and head injury. 4. Of the 185 cases of the pelvic fractures, simple pelvic fractures are 101 cases(54.6%), lateral compression in 39(21.1%), anteroposterior compression in 18(9.7%), vertical shearing in 17(9.2%), mixed pattern in 10(5.4%). 5. Retroperitoneal hematoma and urinary tracts injuries were the most common associated in mixed pattern. 6. The incidence of hemodynamically unstable fractures were 19.8% in simple pelvic fracture but, as expected was higher in major pelvic ring disruptions except to acetabular fracture(52.4%). 7. Mortality rates were 5.9% in all pelvic fractures but 10.7% in major pelvic ring disruptions except to acetabular fractures. Prognostic factor in pelvic fractures were the amount of hemorrhage and associated injuries, therefore early diagnosis and managements are essential to reduce the mortality in pelvic fracture.

A rare case of surgically extirpated intra- and extracranial metastasis of hepatocellular carcinoma is reported. This dumb-bell shaped tumor simulated malignant meningioma on computerized tomography brain scan and cerebral angiography. Removal of the mass was successfully achieved by external carotid ligation and CUSA dissection. We suggest that, when investigating patient with suspected cranial secondaries particulary if there is a bony involvement, serum alpha-fetoprotein and hepatic ultrasound should be carried out as screening procedures.

Functional myelography, applying spinal movements(flexion-extension) in myelography, has been frequently used for accurate diagnosis of posture-related disorders such as herniated lumbar disc or spinal stenosis. Measurements were performed on functional myelographic findings of 62 patients, and in 24 cases surgically verified herniated lumber discs were present. The object of this study was to analyze changes in position and shape of the dural sac in spinal movements and confirm the clinical importance of functional myelography. The present study demonstrated that: 1) The anterior border of the dural sac was straight with flexion, but indented at the level of intervertebral space and this indentation was less prominent at L5-S1. 2) With extension, posterior indentation of the dural sac was more prominent at the level of the intervertebral space than the body, the A-P diameter of the dural sac was narrowed at all levels of the intervertebral spaces except L5-S1, and the dural sac moved anteriorly at the level of L5-S1 and all spinal bodies. 3) In surgically verified disc patients, anterior indentation of the dural sac was persistent in both flexion and extension views, and was more exaggerated with extension, but less prominent at L5-S1. In patient at L5-S1, anterior movement of the anterior dural border at the level of surgery was much decreased.

We analysed ultrasonic findings of 54 brain scan cases(45 cases were performed through the anterior fontanelle and the temporoparietal thin bone and 9 through the surgical bone defect) and comparison of these pictures with those obtained in the same patients by CT scan showed prominent correlation. Ultrasonography was more sensitive to different histologic features and provided a more accurate depiction of the neuropathologic characteristics in most of cases. We conclude that ultrasonography of the brain was proven to be quite useful in the screening and follow up of neonates and infants under 15 months of age, and as a follow up method in post operative patients. It was also more accurate than CT scan in cases of abscesses and cystic lesions.

Cervical traction has been widely used as an essential method for the treatment of cervical fracture-dislocation. This report, however, was a case in which hazardous effect of traction due to unreduced huge fragment was demonstrated only by cervical CT scan. Surprisingly plain X-rays could not demonstrated this condition. It was apparent that skeletal traction resulted in further injury of the spinal cord. Surgical removal of unreduced huge fragment was accomplished completely and interbody fusion was followed. Postoperative CT findings showed complete removal of fragment and decompression of the spinal cord as well as gratifying interbody fusion. CT scanning is imperative to evaluate the cervical fracture-dislocation and blind skeletal traction may be hazardous.

A total of 32 cases of cervical myelography via lateral c1-2 puncture using water-soluble metrizamide was evaluated. Twenty seven cases were suspected to have herniated cervical disc and five cases, spinal cord tumor. Patients were placed in prone position with head and neck slightly extended on the radiolucent operating table. Puncture was performed using 22-guage spinal puncture needle placed at the junction of the middle and posterior one-third of the bony spinal canal and 4-6mm inferior to the arch of atlas on lateral projection. The needle was positioned posterior to the spinal cord into the subarachnoid space. The author could obtain more clear images with less amount of contrast medium than doses used in conventional cervical myelography via lumbar route. The were relatively few adverse reactions and no considerable complications have been encountered with a new cervical water-soluble metrizamide myelography via C1-2 puncture.

Study of 22 cases with the pseudospondylolisthesis established that it occurred more frequently in the older women, and far more frequently at the L4 level, as same results as reported by others. The slipping occurred as a result of degenerative disease of the articular process and facet joint, but it never exceeded 25% in this series. This study was performed to recognize the stability of the lumbosacral joint by the measurement of the anterior and posterior vertical heights(deformity) of the body of the L5 vertebra and lumbosacral angles in our cases. We also attempted to observe whether the facet angle changes at the involved level was meaningful or not. Result : lumbosacral angles in the our patients with pseudospondylolisthesis were increased greater than normal, so lumbar lordosis was less than normal. The body of the L5 vertebra was not as wedged anteroposteriorly as it normally was. The contour of the body of the L5 vertebra resembled rectangle shape. The pedicle-facet angles were increased at involved level, but this measurement was not correctly demonstrated on the plain roentgenograms. Conclusion : The stability of the lumbosacral joint in the patients with pseudospondylolisthesis was increased due to rectangle shape of the body of the L5 vertebra and less lumbar lordosis. The pedicle-facet angles at the involved level were increased, but not correct diagnostic values.

Spinal cystcercosis is extremely rare. But recently was have experienced cervical intramedullary solitary huge cyst, which was confirmed as intramedullary cysticercosis pathologically. Neurological deficits were left hemiparesis, hypoesthesia on the left lower extremity, hyperactive muscle stretch reflex and voiding and defecation difficulty, in spite of its huge size and surgical removal was easy as compared with other intramedullary tumor. There was no adjacent granuloma, granulomatous tissue, not combined with intracranial cysticercosis. Following surgery the patient's symptom were cleared up.
