An epidemiological investigation of 878 workers(male 812, female 66) who suffered from low back injury(LBI) in some workplace of Pusan city from January 1 to December 31 in 1992 was carried out to obtain the various informations of the prevention and management in the occupational low back pain(LBP). The results were summarized as follows: 1. The mean age of LBP workers was 39.3±10.4(18-67) in male 48.5±12.6(21-69) in female workers. And the most common age groups were the 4th decade in male and the 6th decade in female workers. 2. In the frequency distribution of LBI according to the kind of industry, manufacturing industry was most frequent, and industry of construction, transport-storage-communication were the next in order. Among manufacturing industry, LBI of metallic products and machinery was the most frequent. 3. The occupational frequency of LBP was technical worker, monotonous worker, driver of automobile, driver of heavy equipment and office worker in order. 4. The cumulative percentage of LBI was 6.9% at the first day of employment and 90.8% until 10 years after employment. 5. The mean working duration from employment to onset of injury was 1081 days(about 2.9 years) and the working duration according to occupation was the shortest in driver of heavy equipment(502 days) and longest in office worker(1982 days). 6. The careless handling of object was the most common cause of LBI, and fall down, slip down, collision and traffic accidents were the next in order. 7. The most common cause of LBI according to occupation was traffic accident in driver of automobile, fall down in driver of heavy equipment and careless handling of object in office worker respectively. 8. The case of localized LBI were 517(58.9%) and the cases of LBI combined with other injuries, such as head, neck, trunk, arm or leg, were 361(41.1%) 9. Lumbar sprain was the most frequent diagnosis of LBI, and Herniated Nucleus Pulposus(HNP) and lumbar fracture were the next in order. 10. In multiple injuries, LBI combined with multiple body injury was the most frequent, and the next was LBI combined with arm and leg, with trunk, with head and with neck in order. 11. LBI combined with multiple body injury was the main injury in fall down, slip down and traffic accident, and lumbar sprain was the main injury in careless handling of object.

Diseases involving hip may influence on the anatomy of the proximal femur, especially on the endosteal canal shape. The simple radiographic comparative study was performed between normal and diseased hips. For the diseasd hip group, 74 hips ol' femoral head AVN(avascular necrosis) (average age: 49.3 years old, patients were all male) who had limped for average l9 months were selected and 77 male hips (average age: 48.9 years old) who had no prior hip disease were selected for the normal hip group. The external shape of both group showed no significant differences except for the femoral head dimensions. Statistically significant differences were ohserved hetween two groups in the proximal endosteal canal shape and cortical thickness. The femur of the diseased hip group had wider canal from the level of distal to lesser trochanter to the level of isthmus, with a significant reduction in the metaphyseal index (the ratio hetween the canal width proximal to lesser trochanter and distal to lesser trochanter) and the canal flare index (p<0.001). Theoretically this study suggests that the optimal fit and fill to the proximal endostcal canals of normal and diseased hips cannot be obtained by oneshape cementless femoral stcms.

Ankle fractures in children often involve the physis. They are of particular importance because partial or entire growth arrest can occur and result in significant complications. We followed thirty-four ankle fracture involving distal physis of tibia and fibula for more than 1 year and analyzed them using the modified Salter-Harris classification, the Dias-Tachdjian classification and the type of fracture (closed or open), Complications occurred in eight cases (23.5%) – two of twenty-six closed fractures (7.7%) and six of eight open fractures (75%). The complications were more significant in open fractures. Angular deformity (5 cases), limb-length discrepancy (4 cases), incongruity of the joint surface (2 cases), fibular overgrowth (2 cases) and synostosis (1 case) occurred alond or combined. In three cases of them we performed surgical management (bone bridge resection or/and supramalleolar corrective osteotomy) and had satisfactory results. This study suggests that the incidence of complications is difficult to anticipate, but is correlated with severity of initial injuries of growth plate and soft tissue, and is much higher in open fracture. After physeal injury, children should be followed until skeletal maturity and the severe deformities can be prevented by early detection and correction of growth plate disturbance.

PURPOSE: An oblique interface in the right cardiophrenic angle, extending superomedially from rightretrocardiac or supradiaphragmatic region inferolaterally to peridiaphragmatic region, is occasionally observed onposteroanterior chest radiograph. The aim of this study was to evaluate the frequency of visualization of the interface on chest radiographs and to elucidate its nature on radiographic-CT correlation. MATERIALS AND METHODS: Posteroanterior chest radiographs from 300 consecutive subjects were analyzed to evaluate the frequency and demographic data about an oblique interface in the right cardiophrenic angle. Thin-section CT scans(1-mmcollimation and 5-mm intervals) were obtained from the subjects with positive interface on chest radiograph for assessment of the nature of the interface. The demographic data in the subjects with and without the interface were tested statistically to note any difference between two groups. RESULTS: Oblique interface in the right cardiophrenic angle was present in 29 subjects(9.7%) on chest radiograph. The age of the subjects with positive interface(13 men and 16 women) ranged from 19 to 70 years(mean +/-SD, 47+/- 12.7 years) whereas the age of thesubijects without the interface from 16 to 82 years (mean +/-SD, 50+/-9.1 years)(p>0.1). The body weight of thesubjects with the interface ranged from 41 to 72 Kg(mean +/-SD, 60 +/- 8.0Kg) whereas the body weight of thesubjects without the interface from 41 to 85 Kg(mean +/-SD, 63+/-10.1Kg)(p>0.1). On CT scan, it was formed due tocontact between the epipericardial fat and the right middle lobe of the lung in 27 subjects(93%) and between the inferior vena cava and the medial basal segment of the right lower lobe of the lung in two(7%). CONCLUSION: Oblique interface in the right cardiophrenic angle is occasionally visualized on chest radiograph. It is formed due to contact between the right middle lobe of the lung and pericardial fat in most cases. The frequency of visualization of the interface has no relationship to age and body weight of the subjects.

Pericardial defect is a rare congenital cardiac disorder. Most patients were asymptomatic but some patients with partial pericardial defect occasionally complain acute symptoms such as angina, syncope, rarely sudden cardiac death. So, differential diagnosis with other ischemic or structural heart disease is crucial in the management of such patients. But there is no consistently successful diagnostic method. In the past, artificial diagnostic pneumothorax was used to document the absence of pericardium. However, it is not easily accepted due to excess morbidity and failure rate. Recently, echocardiography and more often, computed tomography, magnetic resonance imaging are used to confirm the diagnosis. We experienced a 52 years old male patient with atypical chest pain, who was diagnosed as complete left pericardial defect with computed tomography.

PURPOSE: To clinically establish the effectiveness and safety of bevacizumab on recurrent pterygium. METHODS: Twenty patients with recurrent pterygium were given a subconjunctival injection of 0.3 cc bevacizumab, and were evaluated for periodic clinical results at 1 week, 2 weeks, 4 weeks, and every month thereafter. The patients were also evaluated for clinical results and complications. RESULTS: Of recurrent pterygium patients with bevacizumab injection, the conjunctival injection decreased maximally after 1 to 2 weeks, but significantly increased at 4 weeks (above the lowest level measured at 1 to 2 weeks), and no patient presented conjunctival injection above the pre-injection level at 3 months, except in 2 cases. Two weeks after the injection, ICG anterior segment angiography revealed a significant decrease (30.14+17.69%) in vessel thickness of the pterygium 2 weeks after the bevacizumab injection compared to before the injection. There had been no cases of progression of pterygium, and no ocular or systemic complications due to bevacizumab. CONCLUSIONS: As shown above in the results, subconjunctival injection of 0.3 cc bevacizumab decreased the conjunctival injection and effectively suppressed any further progression of pterygium. Thus, bevacizumab subconjunctival injection appears to be effective in recurrent pterygium treatment instead of surgical methods.

This study was undertaken to prove that the selectively infiltrated parts of nucleus pulposus with indigo carmine was degenerated parts of nucleus pulposus. This study was done, between August and October 2002, in 5 patients, who received endoscopic discectomy, due to intervertebral disc herniation. Discogram was done with mixture of indigo carmine and radioactive dye. Blue discolored part was removed through endoscope, and small undiscolored part was removed together for the control. The two parts were stained with hematoxylin and eosin and compared under the microscope. Undiscolored part was normal nucleus pulposus, composed of chondrocytes with a matrix of type II collagen and proteoglycan, mainly aggrecan. However, in discolored part, slits with destruction of collagen fiber array and ingrowth of vessel and nerve were observed. Using indigo carmine in endoscopic discectomy gives us selective removal of degenerated disc.
