Postoperative CT scans for accuracy of pedicular screw placement were assessed in 20 patients (82 pedicular screws) treated with several kinds of pedicular screws. When putting screws, the position of the guide pin was confirmed by the image intensifier. The measurement of canal encroachment from the medial border of the pedicle and the angle of insertion through the body of each vertebra were assessed; 1. Fifty-five(69.1%) were placed within the pedicle. 2. Ten(12.2%) were placed within 2mm of the medial border of the pedicle. 3. Three(3.6%) had 2mm to 6mm canal encroachment with the patient developing neurologic complication that was improved 8 months after the operation. 4.Fourteen(17.1%) perforated the lateral border of the pedicle, but they were not associated with neurologic complication. 5. The screws placed within 2mm of the medial border of the pedicle had higher angle of insertion than the screws exactly within the pedicle. Even with the use of image intensifier, there was a high rate of pedicle disruption. We have to insert the screws more exactly according to true anatomic angle of the pedicle on each level of every vertebra from the entry point avoiding high angle of insertion to prevent any disruption of the medial border of the pedicle which may result in neurologic complication.

We examined the rates of postoperative neurologic complications, as recorded in the medical record department in Severance Hospital from 1989 through 1991 for patients who had had operations on the spine. There were 538 hospitalizations for procedures on the spine; 327(60.78%) of herniated disc, 120(22.30%) of spondylolisthesis, 64(11.90%) of infection, 27(5.02%) of spinal stenosis were included. Neurologic complications oecurred in 12(2.23%) patients; 3 cases in herniated disc, 4 in spinal stenosis, 4 in spondylolisthesis, and 1 in infection. Regarding techniques of the operation, 8 complications occurred in arthrodesis, among these, 2 were in anterior approach and 6 in posterior approach. Four cases of the complications occurred in laminectomy and discectomy procedure. Complications were more frequent in the patients who had had spinal stenosis when arthrodesis was performed than decompression procedure only. Possible causes of neurologic complication were postoperative hematoma formation, translation of the vertebral column due to instability after anterior debridement and forceful traction of the nerve root during the operation.

PURPOSE: The purpose of this study was to investigate the individual and working environment-related factors affecting hypertension among middle-aged and elderly self-employed workers in South Korea. METHODS: This was a secondary data analysis of data from the Korean Longitudinal Study of Aging (KLoSA). The study sample included 1,319 middle-aged and elderly self-employed workers who were diagnosed without hypertension and older than 45 years at Wave 1 of the KLoSA. Data were analyzed using descriptive statistics and Cox proportional hazards regression analysis using SPSS 20.0. RESULTS: About 20% of the middle-aged and elderly self-employed workers were diagnosed with hypertension within about 8 years from the baseline. the significant predictors of hypertension among the participants were age, diabetes mellitus, body mass index, frequency of health examinations, working hours per week, the presence of regular day off, and the type of job. CONCLUSION: Middle-aged and elderly self-employed workers are vulnerable to work-related health problems. In order to prevent hypertension among self-employed workers, it is necessary to improve the work environment-related factors as well as individual life styles.

Mauriac syndrome consists of a triad of poorly controlled diabetes, profound growth retardation and hepatomegaly. We experienced a case of Mauriac syndrome in an 18-year-old girl who had poorly controlled diabetes mellitus, short stature, hepatomegaly and central obesity. Also at the time of examination, she had complications of diabetic cataract and nephropathy. Fourteen years prior to admission, she was diagnosed as diabetes mellitus at a hospital. Thereafter, she had been managed with irregular insulin injection. On physical examination at admission, her height was 135cm(<3 percentile) and her weight was 39kg(<3 percetile). She was short and obese. The liver was 5 cm palpable below the right subcostal margin. Her sexual maturation was Tanner stage I. On ophthalmologic examination, the cataracts were observed on both eyes and diabetic retinopathy was absent. Diabetic nephropathy could not be confirrned by kidney biopsy due to her mother's refusal. We studied the hormonal, radiographic and histological abnormalities. The hormonal study was normal and the bone age was by delayed as much as 10 years. The liver biopsy revealed glycogen accumulation in hepatocyte. She was consistent with Mauriac syndrome. She was managed by strict diabetic control with insulin therapy, diabetic diet and intensive education. She was discharged with well controlled blood glucose. Five months later, growth acceleration and sexual maturation have not been observed, but hepatomegaly subsided. (J Korean Pediatr Soc 2000;43-837-841)
