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.

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: Anti-HLA antibodies are most frequently induced by transfusion or pregnancy, and these anibodies can be used as antisera for HLA typing. However these antibodies may elicit adverse reactions such as transfusion reaction or rejection of transplanted organs. In this study, frequency and specificities of antibodies against HLA class I antigens were determined in multiparous Korean women. METHODS: Sera from 671 multiparous women were tested for anti-HLA antibody screening by standard microlymphocytotoxicity test using 49~50 lymphocyte panels. PRA(panel reactive antibody) values were calculated as percentage of postive panels among total lymphocyte panels tested. HLA antibody specificities and reaction strengths were determined by analysis of serologic reaction patterns. RESULTS: A total of 671 sera were tested and 124 sera(18.5%) were positive for HLA antibodies. Among HLA antibody-positive sera(n=124), 117(94.4%) showed PRA values of < OR = 50% and only 7(5.6%) showed PRA values of >50%. Specificities of HLA antibodies were identified in 51 sera(41.1%) and 18 sera(14.5%) contained reagent quality antibodies(r> or =0.8, SI> or =70%), corresponding to 2.7% of total multiparous women. Among these, 4 sera had monospecific HLA antibodies and 14 sera had HLA antibodies against two or more antigens: 4 sera containing HLA antibodies against 7 CREG(cross reactive group), 5 sera containing antibodies against 5 CREG. CONCLUSION: Through the analysis of frequency and specificity of HLA antibodies in 671 multiparous women, it is concluded that HLA antisera can be obtained from multiparous women as effectively as from pregnant women. The frequency of high level of sensitization(PRA>50%), which can elicit problems in relation to transfusion or organ transplantation, is very low(1.0%).

BACKGROUND: Third-generation tyrosine kinase inhibitors of the epidermal growth factor receptor (EGFR-TKIs) have proved efficacious in treating non-small cell lung cancer (NSCLC) patients with acquired resistance resulting from the T790M mutation. However, since almost 50% patients with the acquired resistance do not harbor the T790M mutation, retreatment with first- or second-generation EGFR-TKIs may be a more viable therapeutic option. Here, we identified positive response predictors to retreatment, in patients who switched to a different EGFR-TKI, following initial treatment failure. METHODS: This study retrospectively reviewed the medical records of 42 NSCLC patients with EGFR mutations, whose cancers had progressed following initial treatment with gefitinib or erlotinib, and who had switched to a different first-generation EGFR-TKI during subsequent retreatment. To identify high response rate predictors in the changed EGFR-TKI retreatment, we analyzed the relationship between clinical and demographic parameters, and positive clinical outcomes, following retreatment with EGFR-TKI. RESULTS: Overall, 30 (71.4%) patients received gefitinib and 12 (28.6%) patients received erlotinib as their first EGFR-TKI treatment. Following retreatment with a different EGFR-TKI, the overall response and disease control rates were 21.4% and 64.3%, respectively. There was no significant association between their overall responses. The median progression-free survival (PFS) after retreatment was 2.0 months. However, PFS was significantly longer in patients whose time to progression was ≥10 months following initial EGFR-TKI treatment, who had a mutation of exon 19, or whose treatment interval was <90 days. CONCLUSION: In patients with acquired resistance to initial EGFR-TKI therapy, switched EGFR-TKI retreatment may be a salvage therapy for individuals possessing positive retreatment response predictors.

We report here on a case of Achilles tendon rupture associated with ipsilateral bimalleolar fracture that was caused by ski injury. The association of an ankle fracture with rupture of the Achilles tendon is even more infrequent, although both injuries alone are extremely common. We treated as a operation of Achilles tendon repair with Krackow method and open reduction with Tension-band wiring technique for bimalleolar fracture.
