PURPOSE: The aim of this presentation is to analyze the factors influencing on retrograde insertion of double-J catheter in urethral obstruction due to malignancy and to predict the possibility of stunting with double-J catheter. MATERIALS AND METHODS: A retrospective analysis of 43 patients who had underwent retrograde double-J catheter insertion for urethral obstruction secondary to pelvic malignancy, from January 1993 to April 1997, was performed to evaluate the success rates of double-J ureteral stenting according to the factors such as age, sex, presence or absence of flank pain, degree of hydronephrosis, renal function, stage of tumor, laterality of ureter, past history of radiotherapy, operation and chemotherapy. RESULTS: According to the degree of hydronephrosis, the success rate was 100, 73.7 and 50% in grade I II and III, respectively(p<0.05). According to the renal function, the success rate was 81.3% in the group with normal renal function and 45.5% in the group with abnormal venal function(p<0.05) According to the stage of disease, the success rate was 100, 70.7 and 58.3% in stage I, II and III, respectively. According to the absence or presence of flank pain, the success rate was 56.3% in the group with flank pain and 81.5% in the group without flank pain. According to the past history of radiotherapy, the success rate was 65.6% in the group treated with radiotherapy and 90.9% in the group not treated with radiotherapy. The age, sex, laterality of ureter, past history of operation and chemotherapy were not significantly correlated to the success rates. CONCLUSIONS: The factors influencing on double-J ureteral slanting were the degree of hydronephrosis, renal function, absence or presence of flank pain, stage of disease and past history of radiotherapy Further study will be needed to demonstrate the accurate timing of urethral stenting with doublets ureteral catheter.

PURPOSE: This study aimed to assess the risk of developing cardiovascular disease (CVD) and to evaluate the effects of intervention for CVD prevention in construction workers. METHODS: A total of 497 workers participated the health status survey and finally 90 workers were analyzed for evaluation of the intervention with the one-group pretest-posttest design. The data were collected from the questionnaires and health examinations in the healthcare service for road constructor's CVD prevention as secondary analysis. The intervention of the healthcare was composed of CVD prevention education for all workers and face to face counselling for the high risk group of CVD risk during 6 months in workplace. Data were analyzed with descriptive statistics, χ² test, Wilcoxon signed rank test, and paired t-test. RESULTS: The moderate and high risk groups of CVD were 9.7% and 0.8%. After the intervention, the physical activity (MET-min/week) significantly increased (Z=-5.46, p<.001). But, there were no significant differences in blood pressure, fasting glucose, body mass index, and CVD risk appraisals between pre and post intervention. CONCLUSION: The findings imply that it is necessary to develop the health promotion program for construction workers which fully reflects the characteristics of individuals and the organization.

Scapular fractures are being seen with increasing frequency in our mechanized society, specially in patients who have multiple injuries. Most of the scapular fractures have been treated non-operatively, with early mobilization of the shoulder. The result of such functional treatment have been predictably good. However, this non-operative approach may not yield such good results in patients who have a fracture of the scapular neck in association with the ipsilateral clavicular fracture or other double disruptions of the superior shoulder suspensory complex. Ipsilateral fractures of the scapular neck and clavicle disrupt the suspensory mechanism of the shoulder resulting in fuctional loss and deformity. From January 1989 to June 1995, twelve patients were identified with this specific pattern of injury. The follow up period was 39.2 months in average. Seven patients were treated operatively using 3.5mm DCP or reconstruction plate, and five patients were performed K-wire fixation or wiring. Upon review all were healed radiographically. According to the scoring system of Rowe, five patients had an excellent fuctional result, five had a good result, and two had a fare result. The average score for the twelve patients was 85 points. The results of our retrospective study show that operative treatment for these complex fractures is safe and that functional recovery is predictably good.

The purpose of this study was to evaluate the canal configuration after shaping by ProFile, ProTaper and K-Flexofile in simulated resin canals with different angles of curvature. Three types of instruments were used : ProFile, ProTaper, K-Flexofile. Simulated root canals, which were made of epoxy resin, were prepared by ProFile, ProTaper with rotary instrument using a crown-down pressureless technique, and hand instrumentation was performed by K-Flexofile using a step-back technique. All simulated canals were prepared up to size 25 file at end-point of preparation. Pre and post instrumentation images were recorded with Scanner. Assessment of canal shape was completed with Image Analysis program. Measurements were made at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 mm from the apex. At each level, outer canal width, inner canal width, total canal width, and amount of transportation from original axis were recorded. Instrument deformation and fracture were recorded. Data were analyzed by means of one-way ANOVA analysis of variance and the Sheffe's test. The result was that ProFile and ProTaper maintain original canal shape regardless of the increase of angle of curvature than K-Flexofile. ProFile show significantly less canal transportation and maintained original canal shape better than ProTaper.

Hyperornithinemia-hyperammonemia-homocitrullinuria(HHH) syndrome is a rare autosomal recessive disorder caused by a defect in the urea cycle. Protein intolerance, mental retardation, seizure, ataxia, and stupor are characteristic symptoms. Patients showing these symptoms may also present symptoms of acute hepatic disease at the same time. When fed with a high protein diet, they may refuse to eat, vomit, become lethargic, or go into coma. After childhood, most patients avoid meats or milk spontaneously and eat a low protein diet. The liver and spleen are normal or slightly enlarged. The coagulation time is prolonged and sometimes there is a deficiency in factor VII and X. Treatment is aimed at preventing hyperammonemia after meals by restricting daily protein intake to 1.2 g/kg/day and this lowers serum ornithine concentration. Prolonged ornithine supplement(0.5 to 1.0 mM/kg/day; i.e., 66 to 132 mg/kg/day divided into three doses) improved patients' protein intolerance and accelerated growth. Since Shih and coworkers first reported this syndrome in 1969, there have been 40 cases reported worldwide but not yet in Korea. We, for the first time in Korea, report two cases of HHH syndrome in brothers.

We report two very rare cases of postoperative acute spinal subdural hematoma (ASSH) and review the literature. ASSH is usually related to trauma or a previous lumbar puncture, and a review of the literature revealed only a few cases of spinal subdural hematomas occurring secondary to an underlying hematological disorder or to an iatrogenic coagulopathy. However, there have been no reports about the occurrence of ASSH as a complication of uneventful spinal surgery. The authors present two cases of postoperative ASSHs after open lumbar microdiscectomy (OLM) and underline the pitfalls in their diagnosis and treatment modalities. Two patients were treated with surgery, which progressed without sequelae, and their preoperative symptoms were resolved. Postoperative ASSH is an extremely rare complication, but precautions for meticulous hemostasis and careful awareness for minimal manipulation of the dura during lumbar surgery should be considered in all patients, even those who do not require multilevel decompressions and/or who have a preoperative coagulopathy.
