Pulmonary atresia with major aorto-pulmonart collateral arteries(abbreviated as MAPCA in the following)as a route for pulmonary blood flow presents many problem in diagnosis and management and recently new approach to surgical management (unifocalization)was suggested and few reported it's application. Nineteen cases who had pulmonary with MAPCA, diagnosed at Seoul National University Children's Hospital from October 1987 to May 1989, were studied to lool at the relationship between MAPCA, central pulmonary artery and segmental pulmonary arteries. Also was observed the clinical course and operative management. The average number of MACPA in each patient was 4, two toward right lung and the other two toward left lung. MACPA arose most frequently from descending aorta and innominate artery contralateral to the side of aortic arch. Central pulmonary artery was identified in 86.7%. The number of bronchopulmonary segment connected to central pulmonary artery directly or indrectly was very variable so was the number of bronchopulmonary segment connected to MAPCA only. Three had a total correction and 14 had a various kinds of palliative operation once or twice. Seven had a called "unifocalization"(connection of MAPCA to central pulmonary artery) to correct arborization abnormality but the result was not satisfactory for technical reason.

STUDY DESIGN: This study analyzed the efficacy of the reduction and its maintenance using the posterior pedicular screw system in adult patients undergoing surgical treatment for symptomatic, isthmic spondylolisthesis. OBJECTIVE: To evaluate the effect of the reduction for lumbar isthmic spondylolisthesis in adult. SUMMARY OF LITERATURE REVIEW: If the increase of the shear force is approved as a main biomechanical feature of spondylolisthesis, reduction of the shear forces to the physiologic level must be regarded as the goal of surgical treatment. MATERIALS AND METHODS: 11 cases were treated with posterior monosegmental two point f;cation and posterolateral fusion (Group 1), 8 cases with a combined surgery of posterior monosegmental two point fixation, posterolateral fusion and anterior interbody fusion (Group 2), and 20 cases with posterior two segmental three point fixation and posterolateral fusion (Group 3). We assessed the clinical results and the radiologic objective parameters. RESULTS: The patients were followed up for more than 2 years (mean : 64 months). The satisfactory clinical results were 9 cases (81.8%) in Group 1 ,7 cases (87.5%) in Group 2 and 17 cases (85%) in Group 3. Radiologically, the efficacy of reduction and its maintenance were satisfactory results in Group 2, and the changes of the slip angle and the disc height showed that the loss of correction was greater than postoperative correction, although there were no statistical significant differences in the three groups. CONCLUSION: According to the our results, there was no significant relationship between the clinical result and the rdiological one. However, we think that the correcton of the deformity using the posterior pedicular screw system have some biomechanical advantages and seem to be recommendable for the treatment of isthmic spondylolisthesis in adults.

The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (P <0.05, P <0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (P <0.05). Dietary habit score was lower significantly according to the obesity degree (P <0.01). Life style of the subjects was significantly different for the level of 'healthy state (P <0.05)', 'body perception (P <0.01)', 'watching TV and video (P <0.05)', 'normal sleeping hour (P <0.05)' and 'degree of stress (P <0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.
