This study describes our surgical results of transventricular complete repair of tetralogy of Fallot in infants. Material and Method: Eight hundred and forty children underwent complete repair of TOF between January 1990 and April 2002 in our institute. One hundred sixty infants of them were included to this survey. Mean age at repair was 8.1$\pm$2.6 months (3∼12). Correction was accomplished through a short right ventriculotomy less than 30% of ventricular height in all patients. A transannular patch was necessary in 78 patients (49%). Result: There were four early deaths. There were no late deaths. Follow-up with mean duration of 66 months was completed in all survivors, All patients are currently in New York Heart Association functional class I or II. Twenty patients required late reoperations. Actuarial freedom from reoperation at 1 and 10 years were 94% and 87% respectively. Two-dimensional and Doppler echocardiographic follow-up studies showed good right ventricular function in all patients except three. Conclusion: Our results suggested that early complete repair of TOF yield the acceptable results with low mortality and morbidity. Transventricular repair of intracardiac pathology can be safely applied to these patient population, yielding good postoperative right ventricular function.

A case of distal aortopulmonary septal defect associated with aortic origin of right pulmonary ar- tery, patent ductus arteriosus and hypoplasia of aortic isthmus in a 50-day-old female infant is presented. Ligation of patent ductus arteriosus, resection and end-to-end anastomosis of hypoplasia of aortic isthmus, implantation of rlght pulmonary artery to main pulmonary artery and autologous peri- cardial patch repair of aortopulmonary septal defect were performed under cardiopulmonary bypass as one-stage approach. Deep hypothermic total circulatory arrest was applied during repair of hypoplasia of aortic isthmus. The p stoperative course was uneventful.

Clinical therapy that combines full-mouth rehabilitation with immediate implantation and orthognathic surgery poses a challenge to prosthodontists. This clinical report describes a multidisciplinary approach to the diagnosis and treatment of a patient presenting with skeletal discrepancy and rampant caries. The results thus achieved indicate that full-mouth rehabilitation by fixed immediate and early loading implantation accompanied by orthognathic surgery can be a predictable and effective treatment procedure.

Recent advances in understanding the anatomy of complete atrioventricular septal defect have led to alternative methods of repairing these defects. Here we report two cases of complete atrioventricular septal defect repair by direct closure of the ventricular element of the defect. Follow-up for average of 3 months suggests that, when direct closure can be performed, the results can be comparable with those of the standard technique. Our initial success with this approach is encouraging; however, longer follow-up and more experiences are required to establish whether it will be broadly applicable.

The purpose of this study is to compare the status of eyesight according to the change of astigmatism axis in myopic astigmatism and to minimize errors in making astigmatic glasses based on accurate optometry and prescription. The subjects were 93 males and females(186 eyes) who have myopic astigmatism without any ocular disease or systemic disease. We performed comparative analysis on the status of visual acuity according to the change of astigmatism axis to 5, 10 and 15 degree in corrected eyesight 1.0. The direct astigmatism was the most common astigmatism type among the 186 eyes. After all subjects were perfectly corrected into 1.0, the change of astigmatism axis affected eyesight; The results suggested that the more change was made in astigmatism axis, the worse their eyesight would become. The main astigmatism type was changed from direct astigmatism to inverse astigmatism as age increased. The change of the astigmatism axis resulted in failing of corrected eyesight. Therefore, the convergence of examination and correction for astigmatism strength and axis is necessary when conducting refraction inspection for astigmatism.

Even though some authors have reported on the advantages of early total correction of complex heart disease, for low birth weight premature neonates, most surgeons prefer a multi-step approach to early total correction due to the many problems, such as the technical problems, the cardiopulmonary bypass management and etc. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,250 gram premature neonate.

In this paper, we found out the objective refractive errors, the full corrective refractive powers, and the prescriptions for 64 males and 36 females aged 18 to 26 years. To increase the unaided visual acuity 0.1 to the aided visual acuity 1.0 with the glasses, we needed the spherical equivalent refractive power of -3.00D for male and -2.91D for female respectively. To increase the unaided visual acuity 0.5 to the aided visual acuity 1.0 with the glasses, we needed the spherical equivalent refractive power of -0.5D for male and -1.38D for female respectively. Comparing unaided visual acuity and corrective refractive power, the more one has refractive error the less one has unaided visual acuity but these are not linear relationships. Comparing objective refractive error figures, full corrective refractive power figures and prescriptions, objective refractive error figures are the hightest, followed by full corrective refractive power figures. Prescriptions compared with the other two are lower. The cylindrical refractive powers are less than -2.50D. In this study, with the rule astigmatism is dominant over against the rule astigmatism and oblique astigmatism. The accommodation measured by push up method is 6.75D~10.04D for male and 7.50D~9.60D for female respectively.

We experienced a case of anomalous origin of right pulmonary artery from the ascending aorta associated with pulmonary atresia, ventricular septal defect, absence of left pulmonary artery afld multiple major aortopulmonary collateral artery (MAPCA). At ten month of age, left pulmonary artery creation with unifocalization and right pulmonary artery banding were performed as the Urst stage, followed by coil embolization of right MAPCA 1 month later, and 1 year later, the total correction was done. After total repair, the patient showed good postoperative course and excellent angiographic and hemodynamic results at 1 year follow-up study.
