Partial closure of an epiphyseal plate can reduce growth in length and cause angular deformationof the bone. The bone bridge between the epiphysis and the metaphysis, which inhibits growth, can be removed operatively, leaving a cavity, and improvement of the deformity by normal growth is then possible. Previous study have shown that silastic or bone cement diminished both the angular deformity and growth retardation to a highly significant degree. In the present study we wanted to test whether indomethacin and iliac apophysis as an interposition material could prevent bone bridge recurrence following operative removal in adolescent rabbits. It was designed by the concept that cartilage(iliac apophysis) has a specific inhibitory effect on bone formation and indomethacin inhibits bone resorption and bone formation in both heterotopic and orthotopic bone in rabbits. The following experimental groups were designed. Group 1 (N = 7) control group; no interposition material Group 2 (N = 7) iliac apophysis as an interposition material Group 3 (N = 7) only bone wax as an interposition material Group 4 (N = 7) bone wax with administration of indomethacin 10mg/kg/day The results of the study are as follows: 1. In control group, an osseous bridge were revealed as early as 2 to 3 weeks, and this bridging was found consistently in all control groups for the duration of the study. 2. The gmup using iliac apophysis as interposition material was found ineffective for prevention of the formation of epiphyseometaphyseal bone bridge. It was probably resulted from difficulty of its taking from iliac bone. 3. The group using administration of indomethacin after application of bone wax reduced both the angular deformity and growth retardation to a highly significant degree. From the results, it is recommended administration of indomethacin after insertion of silastic or bone cement as an interposition meterial in the elimination of transphyseal closure after physeal damage.

Fractures of the femoral neck in children are rare and usually occur as a result of severe trauma. They are one of the most challenging injuries to treat. Their complication rate is high and their anatomic and physiologic characteristics make treatment difficult. The commonly encountered complications are avascular necrosis, nonunion, coxa vara and premature fusion of epiphyseal plate. Treatment of these fractures remains an unsolved problem but accurate reduction held with adequate internal fixation would appear to offer the best chance for succesful results. We report our observations in the treatment of eighteen cases of fracture of the femoral neck in children. Included is a review of references. The results obtained are as follows: 1. Among 18 patients, 11 were boys and 7 were girls. the highest incidence was between the ages of 5 and 7 years. 2. The main causes of fractures were traffic accidents in 10 cases (55.5%), falling from a height, and slipping down. 3. The commonest type of fracture was the cervicotrochanteric type (47.4%). Twelve cases were displaced fractures (66.7 %). 4. The range of Pauwels angle varied from 20° to 70°. 5. The commonly associated injuries were pelvic bone fractures, extremity fractures, skull fractures and soft tissue injuries. 6. Nine cases were treated by skin traction and plaster cast. Five cases ere treated by closed reduction and internal fixation with K-wires or knowles pins. 7. In 13 of the 18 cases, follow-up studies were done for an average period of 18 months. 8. The results were analyzed according to the Ratliffs assessment. Among the 13 cases, 10 cases showed good results, two fair and one poor. 9. All cases treated by closed reduction and internal fixation showed good results without complications. 10. Complications developed in five cases (38.5%), three cases of avascular necrosis and two cases of coxa vara. Among these five cases, one case of avascular necrosis developed as a result of neglect of the fracture and the others as a result of too conservative a treatment. 11. Secondary treatment of trochanteric arthroplasty was required in only one neglected case. This was further by avascular necrosis and the results were poor. 12. As a result, we recommond closed reduction and internal fixation as the most favorable method of treatment for the fracture of the femoral neck in children.

The age of puberty represents a very critical time in the life history of every young woman. The menarche stands as primary indicator of the onset of sexual maturation in females. According to several studies, menarcheal age in Korean girls has dropped from about 15 years of age in 1960s to 13.5 years of age in 1980s. This findings show a pronounced secular trend to earlier maturation. The purpose of this study is to determine (1) the average age at menarche in Korea in present time, (2) the secular trend of menarcheal age, and (3) the geographic regional influence on menarche. The data sampling was obtained from the physical examination cards of women students in Yonsei University who entered from 1983 to 1991. The data which was obtained from the number of 7761 was analysed by dBase III plus and SAS program. The results are as follows: 1) The mean menarcheal age of the subjects was 13.7+/-1.2 years. 2) Age at menarche has been getting earlier by some 7.4 months during the period of recent II years. 3) Comparing to the decreasing secular trend of menarcheal age, the height and weight showed increasing trend. 4) There were significant differences in menarcheal age, height, weight among geographic regions. We conclude that the results indicate an accelerating secular trend in age of menarche in Korea.

PURPOSE: Regular cancer screening for workers can help prevent cancer or allow early treatment, and is thus beneficial in improving health, reducing costs, and increasing companies' productivity. However, there has been little research on cancer screening rates of workers and related factors. The purpose of this study was to identify cancer screening rates and relevant factors among manufacturing workers. METHODS: Using a questionnaire, data were collected from 335 workers aged over 40 years recruited from seven manufacturing companies. The collected information included cancer screenings (stomach, colorectal, breast, and cervical), attitude towards cancer screening, and demographic and job characteristics. RESULTS: 72.5% of workers received stomach cancer screening (SCS), and 43% received colorectal cancer screening (CRCS). Among 86 women, 68.6% received breast cancer screening and cervical cancer screening. The attitude towards cancer screening was 29.5+/-3.78. Workers aged over 51, married, and those working in mobile manufacturing were more likely to have undergone SCS. Workers aged over 51, married, those working in mobile manufacturing, those in workplaces with more than 1,001 employees, and those with more positive attitudes toward cancer screening were more likely to have undergone CRCS. Finally, attitude affected cervical cancer screening. CONCLUSION: Workers in small-sized workplaces had lower cancer screening rates. Thus, follow-up research should assess the health environment of workplaces and develop educational programs on cancer screening that reflect attitudes towards screening.

Bilateral jumped facets dislocation in upper thoracic spine is rare injury because the thoracic spine is relatively immobile structure. We experienced a case of T2-3 dislocation without fracture and successfully reduced the dislocation after partial resection of the superior articular process of the third thoracic spine and performed fixation and fusion from T1 to T4 with pedicle screw system.

Authors compared early phase scan of the IV bolus CT (two phase incremental bolus dynamic CT) with late enhanecd scan similar to the conventional contrast enhanced CT for evaluation of the advantages of the IV bolus CT with two viewpoints of the pancreatic or peripancreatic mass and peripancreatic lymphadenopathy in 68 patients-28 cases of the pancreatic cancer, 6 cases of the pancreatitis and 34 cases of the pancreatic or peripancreatic metastasis. On the diagnosis of the pancreatic or peripancreatic mass, IV bolus CT could show the lesion(s) more easily in 41% (Grade II; 13/31) and much more easily in 34% (Grade III; 10/31) when compared with conventional contrast CT scan. The diagnosis of the peripancreatic lymph node involvement was also easy in 51%(Grade II; 20/39) and much easier in 37% (Grade III; 14/39). We thought that these differences were originated from the increase of the contrast between the lesion and normal portion because the early enhanced scans reflected the active blood flow change more exactly. Therefore IV bolus CT had advantages in comparison with the conventional drip infusion contrast CT in the diagnosis of the presence and pathologic extension of the pancreatic and peripancreatic lesion.
