This study was performed to estimate the effect of alphacalcidol supplementation or nutrition education on the nutrient intakes, bone mineral density and bone markers in continuous ambulatory peritoneal dialysis (CAPD) patients. The 90 CAPD subjects were randomly assigned to 3 groups (alphacalcidol group: AG, nutrition education group: NG, and control group: CG). Alphacalcidol supplementation(0.5 microgram/day) was carried out for 8 months. Nutrition counseling was performed according to the patient's individual question for the first 6 months and scheduled nutrition education with individual counseling was carried out for the last 2 months. In baseline data, there were no significant differences in age, sex, family number, education years and monthly income except the NG showed significantly less duration of CAPD (p <0.05) compared to other two groups. After intervention all three groups showed tendency of lower intakes. NG revealed less decrease in protein, especially in animal protein, calcium from Ca-P binder, dietary calcium, dietary iron and niacin. NG showed significantly more increase in dry weight (p <0.05) and AG in waist circumference (p <0.001) after intervention. The groups did not show significant differences in the changes of biochemical indices related to bone metabolism. NG revealed more increase in trochanter BMD (p <0.05) compared to other two groups. It seems that nutrition education is more effective in preventing deterioration or improving the bone and general nutrition status.

We designed this study to analyze the causes of repeat surgery in the low back disorder after primary procedure, to evaluate the risk factors and to suggest the rational approachs can prevent and solve the problems related with repeat surgery. We retrospectively reviewed the medical record and radiographs of 24 patients who had sustained persistent or recurrent pain, failed to extended conservative therapy, showing abnormal myelogram and/or CT scan with nerve root compression, and with segmental instability consistent with patients symptom and sign after the primary procedures. We evaluated the functional outcome according to Kims(1986) criteria. The causes of remained or recurrent pain with neurologic symptom were persistent or aggravated lumbar spinal stenosis in 10 cases(42%), recurrent disc herniation in 4 cases(17%), infection in 3 cases(12%), instability in 2 cases(8%) and others in 5 cases(20%). Satisfactory outcome was recorded in 79%(19/24) of patients. The characteristics of the patients associated with satisfactory outcome were those who operated by recurrent disc herniation, instability, retained disc, metal malposition, and nerve root compression by bone chip. But the characteristics of the patients associated with unsatisfactory outcome were those who operated by infection, lumbar spinal stenosis aggravated by degenerative spondylosis and multiple herniated disc, inadequate decompression of lateral and/or foraminal stenosis in aged patients. The most common lesion site was on L4-5 disc, and unsatisfactory result was expected at the upper lumbar spine involvement. Favorable outcome could be expected in the presence of a pain-free interval more than 1 year from the date of the previous operation or persistent symptoms immediately after the initial operaion. We were expected the risk factors leading to repeat surgery were old aged(more than 60) patients, upper lumbar spine involvement and multiple lumbar disc herniation. Postoperative diskitis or osteomyelitis, pain free interval more than 1 month or less than 1 year, and those who had a revision on the lumbar spine previously could be considered as a poor prognostic indicators. When surgery is indicated for degenerative lumbar spinal disorders, adequate diagnostic tests and the execution of appropriate procedures based upon this information should be carried out to prevent the repeat surgery in the low back disorders. Adequate postoperative management can reduce the occurrence of failed back surgery syndrome and in cases necessitating repeat surgery, thorough analysis of causes following proper surgical stabilization can reduce the operative morbidity with early return to daily life.

The ankle is a complex structure supporting the entire musculoskeletal system during standing and walking. The injuries to the ankle joint result in a severe functional disturbance because of complex anatomical characteristics around the ankle joint. 69 patients(72 cases) of the ankle fracture that were treated in Orthopedic Dept. Chonbuk National University Hospital from Jan. 1979 to Dec. 1983 were analized in clinical and radiological aspects. The following results were obtained: 1. Among the 69 patients, male was 54 and female 15 with ratio of 3.5: 1.The average age was 32. 2. Main cause of fracture was traffic accident(58%). 3. The musculoskeletal system was injured most frequently associated with the ankle fracture(66%). 4. According to the ankle fracture classification, the most common type was Pronation-external rotation type in Lauge-Hansen classification, and the type C in Weber classification. 5.The average duration of cast immobilization was 8.8 weeks in closed reduction and 7.4 weeks in open reduction. 6. The lateral malleolar fracture involving the distal tibiofibular syndesmosis was very important in ankle stability so accurate anatomical reduction by internal fixation was necessary for satisfactory functional results. 7. In clinical and radiological analysis, the better results were obtained from open reduction.

BACKGROUND: Osteoporosis is an important health concern among the postmenopausal women. Therefore, it is necessary to find out acceptable screening tools for osteoporotic patients. The purpose of this study was to evaluate the Risk Index by OSTA as a screening test for osteoporosis. METHODS: The study population was 322 naturally caused menopausal women in Korea. Their was of femoral neck and lumbar spine BMD measured by DEXA. Risk Index by OSTA, based on weight and age, was calculated and the sensitivity and specificity for osteoporosis and osteopenia were evaluated. To find out the proper cut-off point for osteoporosis and osteopenia among the postmenopausal women in Korea, we also compared the sensitivity and specificity of each Risk Index value. RESULTS: The mean age and ages at menopause were 59.1(+/-6.2) and 50.7 (+/-2.7) years, respectively. The prevalence of osteoporosis was 9.6% with femoral neck BMD. For oeteoporosis, using a cut-off point of -1 yielded a sensitivity of 74.3% and a specificity of 52.2% with femoral neck BMD. Using a cut-off of -2 yielded a sensitivity of 87.3% and a specificity of 70.9%. The ROC curve showed an AUROC 0.88 for Risk Index in identifying osteoporosis. CONCLUSION: The Risk Index is an acceptable, simple and useful method in the diagnosis of osteoporosis with a Risk Index of -2 in Korean postmenopausal women.

OBJECTIVE: Neonatal blood pressure is one of the vital signs used to assess the general health of a newborn infant. But, it is difficult to measure and varies according to the model of sphygmomanometer, the used method, the postconceptional age, birth weight, asphyxia, postnatal age and activity. We have assessed the rnean value of blood pressure(BP) according to postconceptional age. Variations caused by the postconceptional age, birth weight, body surface area(BSA), postnatal age, and sex were analyzed to determine the rnost important factor influencing the neonatal BP. METHODS: This study included 448 normal fullterm infants and healthy preterm infants born from Jan. 1995 to Aug. 1997 at Ewha Dongdaemoon and Mokdong Hospital. The BP was taken on day 1, 3, 5 with the oscillometric device(Dinamap 1846 critikon Inc.), for premature infants BP was followed up every week afterward. RESULTS: The neonatal BP was related to the postconceptional age(R=0.204, P<0.05), BSA(R =0.191, P<0.05), birth weight(R=0.183, P<0.05) and the postnatal age in fullterm infants(R=0.022, P<0.05) but not with the sex of the infant. The postconceptional age was the most significant variable among those influencing the BP. The normal value of the systolic and the diastolic BP was expressed as mean+/-2SD according to the postconceptional age, less than 28 weeks(n=27) systolic/diastolic pressure 50.4+/-23.1mmHg/26.2+/-12.8mmHg, 28-32weeks(n= 63) 60.1+/- 30.6mmHg/33.6+/-16.7mmHg, 32-36weeks(n = 139) 63.2+/- 20.4mmHg/37.7+/- 19.8 mmHg, 36- 40weeks(n=543) 65.6+/-18.5mmHg/38.6+/-17.3mmHg, more than 40weeks(n= 136) 67.7+/-16,9mmHg/39.3+/- 15.8mmHg. The increase in blood prssure with the postconceptional age was statistically significant. CONCLUSION: The normal range of neonatal BP, especially preterm infants, was presented, and it would be much valuable for the evaluation of BP in neonate if standardized by postconceptional age.

PURPOSE: This study aims to assess the effects of psychosocial work environment and self-efficacy on stress, depression, and burn-out among office workers. METHODS: Survey data were collected from 331 office workers who worked in one workplace from April 10 to 30, 2012. The impact of psychosocial work environment and self-efficacy on stress, depression, and burn-out was analyzed with hierarchical multiple regression using SAS version 9.3. RESULTS: Work-family conflicts and emotional demands were identified as main factors influencing mental health. Other work environment factors influencing mental health were role clarity for stress, possibilities for development, meaning-of work, social support-from supervisors and job insecurity for depression, and social community at work for burn-out. Self-efficacy was correlated with most psychosocial work environment and factor with independent influence on stress and depression. The final models including general characteristics, psychosocial work environment, and self-efficacy accounted for 34%, 44%, and 36% for stress, depression, and burn-out respectively. CONCLUSION: To promote mental health in office workers, there is a need to decrease work-family conflicts and emotional demands and to improve work organization and job contents, social support, and self-efficacy.
