Focal nodular hyperplasia is a benign hepatic tumor mainly composed of nodules of hepatocytes and Kupffer cells separated by fibrous septa. In general, it is difficult to differentiate focal nodular hyperplasia and hepatocellular carcinoma on ultrasonography, conventional CT(computerized tomography), and angiography. But IV bolus CT is of particular value in the diagnosis of focal nodular hyperplasia because it can divide enhanced CT into early and late phase and can characterize tumor vascularity and analyze any intratumoral elements. In our case, it was seen as a hypoechoic mass lesion on ultrasonograpl'hy and hyperdense mass lesion on early-phase IV bolus CF and isodense mass, lesion on late-phase IV bolus CT. On angiography, hypertrophy of the feeding artery and tumor staining were well visualized. The patient underwent operation and the mass was pathologically confirmed to a focal nodular hyperplasia. We report the first case of focal nodular hyperplasia on IV bolus CT in Korea.

We reviewed 23 patients of injury to the spine who were under 15 years of age and treated at Wonju Christian Hospital from January, 1978 to December, 1987. The patients were classified into 3 different categories, that were frsctures(17 cases), dislocations(3cases), and fracture-dislocation(3 cases). We analyzed the cause of injury, sexage distribution, treatment and neurological injuries. The results were as follows : l. Among the 23 cases, there were 16 boys(70%) and 7 girls(30%). The mean age was 11 years of age, and ages of active period, that is 10 to 15 years of age, were most common, 17 cases(74%). 2. The most common cause of injury was fall from a height, 13 cases(57%). The most common location of injury was cervicsl spine, 10 cases(43%) and among these cases, injury to upper cervical portion(C1–C3) was more common than lower cervical portion(C4–C7). 3. The cases of multiple compression fracture were 6 patients(26%), and all cases were located thoracic or thoraclumbar junction. 4. Most cases were stable spinal injury, 18 cases(78%), and the most common mechanism of injury were compreesion injuries due to hyperflexion, 15 cases(65%). 5. The most common associated injury was head injury, 9 cases(39%), and associated neurological complications were in 4 cases, 3 cases of these were recovered. We could ascertain that the prognosis of children spinal cord injury is better than that of adult. 6. Restoration of the height of the involved vertebral bocy occurred in all but one compression fractures of vertebral body. 7. There were 3 cases of epiphyseal injury, 2 of these were epiphyseal separations of odotoid process of atlas, the other was fracture of lumbar vertebral apphysis. 8. All but two were treated conservatively and the results were good. In stable spinal injury, we considerded that the duration of treatment was 4 to 6 weeks.

Surface ECG findings in 29 patients with left isomerism were reviewed. Among the total 46 wave axis distributions, 25(54%) were abnormal axis, not originated from sinus node. Congenital atrioventricular block was found in 2 children. 6 patients showed the bradycardia and junctional escape rhythm intermittently or persistently. 4 of them, not related with heart surgery, were much older than 2 patients who showed these ECG findings after heart surgery. These ECG findings suggested the possibility of occurrence of sinus node or subsidiary pacemaker dysfunction in the patients with left isomerism, especially in the older patients. So we thought that electrophysiologic evaluation is necessary in some patients with left isomerism.

Since introduction of venous flap in 1980, many experimental studies and clinical applications of various kinds of venous flaps were reported. Venous flap has the following advantages : (1) nonbulky and goo-quality of flap (2) long & large vascular pedicle (3) easy & rapid elevation of flap (4) no sacrifice of major arteries (5) a single operative field. But, we also have some disadvantages of difficult handling of the pliable veins and the tmcertainty of flap survival. For the better result we had to design the size of the flap larger than that of defect and increase the number of draining vein to reduce the postoperative edema of the flap. We have treated the defects of soft tissue of the hand using free arterialized venous flap from the flexor aspect of the forearm & had an excellent results.

We report a case of myelodysplastic syndrome (MDS) with unique histopathological findings in which numerous infiltrated neutrophils exhibited nuclear segmentation anomalies. In comparison with well-described neutrophilic dermatoses of myelodysplastic syndrome such as Sweets syndrome and pyoderma gangrenosum, this case took a rapid and aggressive clinical course. We suggest that a nuclear segmentation anomaly, pseudo Pelger-Hiiet anomaly, is likely to reflect acute transformation of MDS and can be a poor prognostic marker.
