Bladder mucosa has been reported as an excellent tissue for construction of a neourethra. We used bladder mucosa in 3 cases when there was inadequate foreskin to create a neourethra. Two cases were penoscrotal hypospadias with chordee which were repaired in one stage operation and one case was scrotal hypospadias with severe chordee which was repaired in two stage operation. The. sizes of harvested bladder mucosa were 4x 1.5cm, 10 x 3.5cm and 15 x 3cm respectively. Two minor and one major complications occurred. The minor complications were urethral stricture in one case which was managed with urethral dilation and penile swelling after self-voiding in one case which required urinary diversion for several days. In one case severe problem with entire neourethra stricture necessitated internal urethrotomy and intermittent urethral dilatation. In all cases sufficient graft tissue could be obtained and there were no urethrocutaneous fistulas. Thus, the use of bladder mucosal graft in hypospadias repair is feasible in cases in which previous repairs have railed or in which sufficient foreskin for neourethral reconstruction is lacking.

This study was conducted to evaluate the postnatal changes of serum creatine kinase (CK) and its isoenzymes in normal and asphyxiated newborns. In normal newborns total CK, CK-MM and CK-MB reached a plateau between 2 and 24 hr after birth whereas the serum CK-BB remained stable after birth. CK-MM, CK-MB and CK-BB respectivily composed 90~94%, 5~7% and 1~5% of total CK during study period. In asphyxiated newborns total CK, CK-MM and CK-MB reached maximal value at 12 hr after birth whereas CK-BB decreased after birth. There were no significant differences between normal and asphyxiated newborns in total CK, CK-MM and CK-MB during study period (up to 24 hrs after birth). But CK-BB of asphyxiated newborn was elevated significantly (p<0.05) within 6 hrs after birth compared to normal newborns. There were no significant differences of CK and its isoenzymes between patients evaluated by 5 min Apgar scores(0~3, 4~6 and 7~10) or degree of HIE (HIE stage 0~I, II and III). According to these results, the serum CK-BB is elevated in asphyxiated newborns during 1st 6hrs after birth but has no predictive values of the extent of cerebral damage.

Two cases report on osteogenesis imperfecta tarda and review of literature has been made. The rare genetic disorder, osteogenesis imperfecta tarda is familiar to most orthopedic surgeons because of management of fracture and skeletal deformities, espicially bowing of long bone. Its clinical manifestations are known as bony fragility, blue sclera and deafness less frequently ligamentous laxity but its etiological factor is obscure; The basic defect is thought to involvement some abnormality of collagen. Recently the bony weakness caused by increased bony turnover rate. One case of osteogenesis imberrfecta tarda in 8 year old male was belonged to tarda type 1. (Falvo-classification), who could not walk due to marked anterolateral bowing of right tibia and the another to tarda type II. in 13 year old male with fresh fracture of right femoral shaft. The former was performed corrective multible osteotomy, realignment and intramedullary rod fixation for correction of bowing deformity of right tibia, and the later was managed the fracture of right femoral shaft with Russels traction and hip spica cast. The result of reported therapeutic mesure was good.

PURPOSE: This study was conducted to compare the PET and CT findings for patients with a pulmonary lymphangitic metastasis. MATERIALS AND METHODS: We retrospectively reviewed the PET and CT findings of seven patients diagnosed with a pulmonary lymphangitic metastasis between May 2005 and May 2007. RESULTS: All patients had interstitial thickening, as seen on a CT scan, while the PET scans showed abnormal findings in only three patients. In these three patients, one patient had interlobular septal thickening of more than 10, another patient had interlobular septal thickening of more than 5 but less than 10, and another patient had interlobular septal thickening of less than 5. All of the patients had bronchovascular bundle thickening. However, among the four patients that had normal FDG uptake, no patient had interlobular septal thickening of more than 10, two of the patients had interlobular septal thickening of more than 5 but less than 10, and the remaining patients had interlobular septal thickening of less than 5. Only two of the patients had bronchovascular bundle thickening. CONCLUSION: All patients with pulmonary lymphangitic metastasis have typical CT findings, but some of the patients had FDG uptake, as seen in the PET scans. Thus, CT is a more useful modality for diagnosis for pulmonary lymphangitic metastases.

OBJECTIVES: To investigate the relationship between job stress and the variables associated with the organizational effectiveness of dental technicians. METHODS: The job stresses were divided into the following six components; somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and hostility. The organi-zational effectiveness variables in this study included job satisfaction, occupational commitment, organizational commitment and intent to leave. The sample used in this study consisted of 248 dental technicians working in hospitals and dental laboratories. The data were collected with self-administered questionnaires between March 16 and April 29 in 2002, and the results analyzed with ANOVA and multiple regression analysis. RESULTS: Firstly, job stress of dental technicians was found to be significantly different in relation to the number of workers at the workplace and the working hours. The level of job stress was the highest when the number of workers were more than 10, or when the daily working hours were over 12. Secondly, of the six variables of job stress, five variables of somatization, interpersonal sensitivity, depression, anxiety, and hostility were found to have significant negative correlations with job satisfaction. Thirdly, all six job stress variables were found to have significant negative correlations with the occupational and organizational commitments of the dental technicians. Finally, depression was the only job stress variable found to have a significant effect on the dental technicians' intent to leave. CONCLUSIONS: The results of this study indicate that personal and organizational efforts are very important to improve the organizational effectiveness in reducing work related stress. Organizational support, especially for managing the depression of dental technicians is recommended.

OBJECTIVE:The purpose of this study is to evaluate the CT findings of the carcinoma of the ampulla of Vater and to differentiate from other periampullary carcinoma including the carcinoma of the distal common bile duct and pancreas head. MATERIALS AND METHODS: We retrospectively reviewed the CT findings of 13 cases of the carcinoma of the ampulla of Vater, 20 cases of the carcinoma of the distal common bile duct and 20 cases of the carcinoma of the pancreas head confirmed by pathology. Five millimeter consecutive settings of CT scan were performed in all cases on ampulla level with supine position. The CT findings were retrospectively evaluated in view of common bile duct dilatation, pattern of termination of bile duct, pancreatic duct dilatation, protruding mass in duodenal lumen, and regional lymph node metastasis. RESULTS: All case of the carcinoma of the ampulla of Vater(13/13) and distal common bile duct(20/20) showed common bile duct dilatation with abrupt termination. Among the 10 cases of the carcinoma of the pancreas head with common bile duct dilatation, five cases each had is abrupt termination(5/20) and gradual stenosis of bile duct(5/20). Five cases of the carcinoma of the ampulla of Vater(5/13) and four cases of the carcinoma of distal common bile duct(4/20) showed pancreatic duct dilatation and all cases of the carcinoma of pancreas head show pancreatic duct dialtation(20/20). Twenty cases of the carcinoma of the ampulla of Vater showed protruding mass in the medial wall of the second portion of the duodenum(12/13) but only one case of the carcinoma of the distal common bile duct(I/20) and five cases of the carcinoma of the pancreas head (5/20) had protruding mass in the duodenal lumen. Only one case of the carcinoma of the ampulla of Vater showed(1/13) regional lymph node metastasis but three cases of the carcinoma of the distal common bile duct(3/20) and 18 cases of the carcinoma of the pancreas head(18/20) showed regional lymph node metastasis. CONCLUSION: Common bile duct dilatation with abrupt termination, protruding mass in the duodenal lumen and rare lymph node metastasis in CT may suggest the carcinoma of the ampulla of Vater.
