Spontaneous spinal epidural hemorrhage(SSEH) represent 0.3%~0.9% of spinal epidural-space-occupying lesions. The therapeutic outcome seems to be determined by the accuracy of the diagnosis and by the time interval between the onset of symptom and surgical decompression. Thus, SSEH is a rare spinal emergency and a diagnostic challenge. We experienced two such cases. In one case, the symptoms were confused with those for a ureter stone, aortic aneurysm, spinal cord infarction. That patient completely recovered spontaneously within 2 hours. In the other case, which was initially diagnosed incorrectly as a cerebral infarction, surgical decompression was performed. That patient recovered completely within 1 month.

Between 1987 and 1992, 86 tibial fractures were treated with the Ilizarov external fixator at Gyeong-Sang National University Hospital and Okpo Hospital. The mean follow-up period was 31.4 months. Sixty-six were open fractures and twenty were closed fractures with severe comminution. In 66 open fractures, there were 9 Gustilo type I, 10 type II, and 47 type III fractures. Of 66 open fractures, 22 had bone defects ranged from 2cm to 17cm and 16 had extensive loss of soft tissue. Twenty-two bone defects were treated with cancellous bone grafts in 8 cases, bifocal osteosynthesis with bone graft in 12 cases, and trifocal osteosynthesis with bone graft in 2 cases. Thirty-four extensive soft tissue defects were treated with split-thickness skin graft, musculocutaneous flap, soft tissue transportation with ring used in bifocal, trifocal osteosynthesis, and acute shortening of fracture site. Of 20 closed fractures, 14 were treated with cancellous bone graft for decreasing union time and 6 were treated with monofocal compression without bone graft. The mean time to union was 20.5 weeks in closed fractures, and 35.4 weeks in open fractures. Of 40 complications, 12 were knee and ankle joint contractures, 12 were soft tissue and bone infections of pin tract, 5 were refracture, 5 were angular deformities of 10 degree or more, 5 were delayed union, and 2 were nonunion. According to Tucker's classification, the results were graded as excellent in 31, good in 38, fair in 12, and poor in 5 cases. Primary or secondary bone graft is necessary for early bony union and anatomical reduction combined with bone graft could prevent the complications of delayed union and nonunion.

BACKGROUND: HLA-DR typing kits using reverse-SSO (sequence specific oligonucleotide) method show considerable ambiguities in HLA-DRB1 generic typing. We analyzed the ambiguities of the Dynal RELI(TM) SSO HLA-DRB test (Dynal DRB test) and developed an 'Interpretation Program for Koreans'. METHODS: A total of 3,000 Koreans were typed for HLA-DRB1/B3/B4/B5 using the 36 probe Dynal DRB test and all of the cases showing ambiguities in HLA-DRB1 generic typing were subjected to confirmatory typing using the PCR-single strand conformation polymorphism (SSCP) method. On the basis of these results, an 'Interpretation Program for Koreans'was developed for the 45 probe Dynal DRB test. RESULTS: Among 3,000 Koreans tested by the 36 probe Dynal DRB test, 456 cases (15.2%) showed ambiguities. In 95% of the ambiguity cases (433/456) and 99.2% of the total cases tested (433/3,000), the'most probable type'could be expected from the DRB1 gene frequencies and DRB1-B3/B4/B5 associations in Koreans and these results were in accordance with the confirmatory typing results as well as the results given by the 'Interpretation Program for Koreans'. Similarly, the 'Most Probable'could be assigned by the program in 99.4% (348/350) of the cases tested with the 45 probe Dynal DRB test. CONCLUSIONS: Ambiguity in the Dynal DRB test was observed in >15% of the Korean samples tested. The majority (95%) of the ambiguities could be resolved on the basis of HLA-DRB1 gene frequencies and DRB1-B3/B4/B5 associations in Koreans. Furthermore, using the program developed in this study, the correct assignment of DRB1 generic types was possible without additional typing in the majority (>99%) of the cases tested.

BACKGROUND: The present study was done to evaluate the usefulness of SDS-PAGE in measuring glomerular proteins and tubular proteins in patients with type I DM without overt proteinuria. METHODS: The study population consisted of 76 children with type I DM who have been participated in the Taegu Diabetic Camp from 1997 to 2000. We measured urine albumin, NAG, beta2-microglobulin, creatinine level in urine samples collected for 12 hours in 22 children and simultaneously we analyzed urinary proteins by SDS-PAGE. In remainder 54 children, we measured urine albumin, NAG, creatinine level in random morning urines and urinary proteins by SDS-PAGE. RESULTS: In 22 of 76 children, urinary albumin-to-creatinine ratio (mg/mg), NAG (U/g) and beta2-microglobulin (microgram/g) were 0.021, 2.99 and 170.2, respectively. Positive correlation between urine albumin and NAG was statistically significant (r=0.51, p< 0.05). No significant relations between urinary proteins, such as albumin, NAG, beta2-microglobulin, and clinical characteristics, such as age, duration of illness, HbA1c, were observed. In diagnosing `microalbuminuria', sensitivity of SDS-PAGE was 63% and band of tubular proteins was not detected in any children. CONCLUSION: We thought that SDS-PAGE could be one of useful methods in diagnosing early stage of diabetic nephropathy. The more large scale study is necessary.

PURPOSE: We aimed to investigate the cardiopulmonary effects of pressurized cement insertion in elderly patients undergoing cemented hip hemiarthroplasty. MATERIALS AND METHODS: We conducted a randomized prospective study on elderly patients undergoing cemented hip hemiarthroplasty. Patients were divided into pressurized and non-pressurized groups based on the pressure application during cement insertion. We measured mean arterial blood pressure (MAP), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), arterial blood gases and serotonin concentration in blood. These variables were measured before bone cement insertion, and 3 and 5 minute after insertion. They were also measured immediately and 15 minutes after reduction. RESULTS: In cemented hip hemiarthroplasty, there were no significant change in MAP (P=0.92), SBP (P=0.85), DBP (P=0.98), HR (P=0.97) and serotonin concentration over time. There were no statistically significant difference between the two groups in MAP, SBP, DBP, HR, PO2, PaCO2, SaO2 and serotonin concentration, though three minutes after cement insertion, both groups showed decreases in SBP, DBP and MBP. CONCLUSION: The pressurization method in cemented hip hemiarthroplasty was not found to be related with development of bone cement syndromes in elderly patients.

BACKGROUND: Opioid tolerance may involve activation of the N-methyl-D-aspartate (NMDA) system. The possible involvement of the NMDA system suggests that one of the NMDA receptor antagonists, magnesium may be a useful adjunct to opioids for the treatment of postoperative pain following remifentanil infusion. METHODS: For this study, 70 patients scheduled for major abdominal surgery under remifentanil-based anesthesia were randomly allocated into groups that received either magnesium sulfate (group M) or saline (group C) intravenously. The patients in the group M received 25% magnesium sulfate at a dose of 50 mg/kg in 100 ml of saline, and those in the group C received an equal volume of saline prior to the induction of anesthesia. In addition, patients in both groups received 10 mg/kg/h infusion of either magnesium sulfate (group M) or an equal volume of saline (group C) until the end of surgery. Pain was assessed using a visual analog scale at 30 min, and 6, 12, 24, and 36 hours after operation. The time to the first use of postoperative analgesic and cumulative analgesic consumption in both groups were also evaluated. RESULTS: The visual analog scale scores for pain and cumulative analgesic consumption were significantly lower in the group M than in the group C. The time to the first use of postoperative analgesic was significantly shorter in group C than in the group M. CONCLUSIONS: Use of the NMDA-receptor antagonist, magnesium sulfate as an adjuvant analgesic reduced postoperative pain in patients undergoing major abdominal surgery under remifentanil-based anesthesia.

BACKGROUND: Early oral intake (EOI) associated with early recovery of normal bowel function has been shown to be an important determinant for improving patients' satisfaction. We investigated the tolerability of EOI and its effects on the recovery of bowel function after epidural anesthesia. METHODS: A prospective randomized trial of patients undergoing lower extremities surgery under epidural anesthesia was performed. A liquid drink was given to 150 patients in the EOI group 1 hours after surgery, and to 150 patients in the delayed oral intake (DOI) group 8 hours after surgery. We recorded presence of bowel sounds immediately after operation, symptoms of ileus, time to the first flatus, time to the first defecation, degree of appetite before the first meal, and patients' satisfaction. RESULTS: There was no significant difference in the presence of immediate postoperative bowel sounds, the degree of appetite before the first meal, mild ileus, and severe ileus between groups. Time to the first flatus and time to the first defecation in the EOI group were shorter than those of the DOI group. The patients' satisfaction in the EOI group was higher than that of the DOI group. CONCLUSIONS: For uncomplicated patients undergoing lower extremities under epidural anesthesia, beginning oral hydration as early as 1 hour after the operation is safe and well tolerated and resulting in faster recovery of bowel function and higher patients' satisfaction.
