Long segmental fixation with TSRH posterior instrumentation for 19 patients who had unstable thoracolumbar fracture was performed between October 1992 and April 1995. The patients were followed for an average of 22 months. Measurements of the deformity angle, kyphosis, vertebral height, and the intervertebral angle were made. The patients were divided into 2 groups according to configurations of instruments for lower segmental fixation. For one group, only hooks were used, and for the others group pedicular screws and lateral offset hooks were used together at the same segment. Therefore, the purpose of this study is to anlyze the correctability following long segmental fixation and to compare one segmental fixation using both screws and lateral offset hook systems with two segmental fixation using hook systems for distal fixation. There was an overall correction of kyphosis at follow-up of 6.9degrees (27.1%) after a loss of 4.3degrees from operative correction. Overall correction of deformity angle was 8.2degrees (32.2%). Loss of vertebral height at final follow-up was 4.4%. And loss of intervertebral angle was 2.0degrees at follow-up. There was no difference of overall results between the hook group and the pedicular screw with lateral offset hook group. However, there was a significant improvement of the correction of kyphosis and restoration of vertebral height in patients who underwent operation within 7 days after injury, as compared to delayed operation. Therefore, the timing of surgery is the most important factor in order to correct the deformity caused by unstable thoracolumbar fractures. There was no significant loss of correction and no metallic failure. Therefore, rodding long with the method of one segment distal fixation using screws and lateral offset hook together can provide excellent correctability, maintenance of correction, preservation of distal lumbar joints, prevention of implant failure and complication.

Utile recently, osteotomy & reposition surgery of prominent zygoma have been performed by means of a coronal incision or intraoral preauricular incision. But penalties are paid, such as scar, the possibility of facial nerve injury and long operative time. Reflecting on our past experiences of facial bone surgery, we developed an alternative approach. In our method, the protrusion in the cheekbone is corrected by performing an osteotomy and reposition method through intraoral incision only. During the past 3 years we have operated on 23 patients of malar prominences. The amount of the bone to be removed is determined on preoperative interview, physical examination and x-rays. Intraoral incision provide access to the zygomatic body and lateral orbital rim. After L-shaped osteotomy, two paralle vertical and one transverse osteotomies, at medical part of the zygomatic body, the midsegment is removed. Posterior portion of zygomatic arch was approached through medical aspect and was outfractured using curved osteotome. After completion of triple osteotomy, the movable zygomatic complex was reduced medially and fixed with miniplates and screws on the zygomaticomaxillary buttress. The patients were followed for 9.5 months with acceptable result and little complication. The author concludes that this technique is effective and safe method in reduction malarpalsty.

Through the clinicopathologic study of pathergy test sites of 16 patients with Behrets disease in the active or inactive stage, the following results were obtained; 1. In the active stage, six of 16 patients (37.5%) showed positive reactions in clinical pathergy tests, which are much higher than that in the inactive stage when only one patient showed a positive reaction. The severity of the ciniral pathergy reaction was directly related to the activity of the disease. 2. The characteristic histopathologic finding in the active stag was a dermal inflammatory cellular infiltration composed mainly of polymorphonuclear lukocytes and of lymphomononuclear cells accompanied by leukoctocylasia. Two of 16 patients showed true leukocytoclastic vasculitis. 3. Although the type of disease and the reactivity of the clinical pathergy test were related in terms of the severity of the histopathologic findings, there were some notible histopathologic changes even in the cases with negative clinical pathergy reactions. We concluded that the histopathologic findings of the pathergy test sites were more reliable for the diagnosis of Behcet's disease than the clinical findinigs.

BACKGROUND: The skin prick test and in vitro allergen-specific IgE assays are commonly used to diagnose atopic diseases. However, there is still a need for comparison of their diagnostic efficiency. Objective and METHOD: To evaluate their clinical efficiency, the results of UniCAP and multiple antigen simultaneous test (MAST) were compared with skin prick test results. After 51 allergic patients completed skin prick test (SPT), serum sample was collected and UniCAP and MAST were performed to determine specific IgE to house dust mite (Dermatophagoides pteronyssinus : Dp and D. farinae. Df). Result : When SPT was used as a reference standard, UniCAP depicted higher sensitivity of 88.8% to Dp IgE and 91.4% to Df - IgE, but lower specificity of 73.3% to Dp IgE and 75.0% to Df - IgE. However, MAST had lower sensitivity of 75.1% to Dp-IgE and 71.4% to Df - IgE, higher specificity of 93.3% to Dp-IgE and 93.7% to Df - IgE. The values of UniCAP and MAST were significantly correlated with the reactivity grade of skin prick test, respectively. Additionally, the response of SPT was not apparently associated with ECP levels. CONCLUSION: These study results may suggest that both UniCAP and MAST are generally feasible for measuring house dust mite - specific IgE and that they are both replicable.

The eye is a common target organ of the allergy, and allergic conjunctivitis is the most common of eye diseases. Clinical manifestations of allergic conjunctivitis are acute bilateral red, itchy, and watery eyes. The presence of conjuncitival eosinophilia may be consided to be a diagnostic indicator of allergic conjunctivitis. ECP is a quantifiable toxic product secreted by activated cosinc phils. VCAM-1 promotes adhesion of leukocytes to endothelium in vitro and may promote imflammation in vivo. The objective of this study is to measure eosinophil count, ECP and sVCAM-1 levels of tears and sera in patients with acute allergic conjunctivitis and normal subjects and to assess the correlation of these mediators with the severity of the disease and the clinical usefulness. Seventeen subjects were selected on the basis of clinical manifestations, history, skin prick test, total IgE. A microcapillary tube was used to collect the tears from the inner canthus, conjunctival epithelia were obtained for eosinophil count by scraping the upper tarsal conjunctiva. The level of ECP was measured by CAP system (Kabi-Pharmacia, Sweden), sVCAM-1 was measured by ELISA (R&D, USA). Serum IgE and eosinophil count were in creased in 10 patients, allergic skin prick test were positive in 11 subjects (D.p: 9, D.f: 8), eosinophilia in conjunctival epithelium were present in 11 subjects (4 patients: > 3/HPF, 7 patients: 1-3/HPF). ECP in tears were increased in patients significantly (12.0+8.0 vs 3.9+3.8 ng/ml, p=0.01), but not in serum (52.5+43.1 vs 28.3+25.9 ng/ml). There is no significant correlation between eosinophil count and ECP in serum and tears (p>0.05, r-=0.19). Serum sVCA-M-1 level is significant different between patients and controls (1916.5+756.0 vs 1147.2+146.1 micro gram/ml, p=0.01), sVCAM-1 is significantly correlated to eosinophil count (p=0.01, r=0.56) and ECP (p<0.05, r=0.65). In conclusion, eosinophil and ECP in tears may be very important role in allergic conjunctivitis and are useful indicators of the disease. The elevation of sVCAM-1 in serum may be interpreted simply as marker of the presence of non-specific inflammation.

Thl cloned cell line 28-4 which is an I-A + KLH - specific Th1 type clone of (C57BU6xC 3H) F1 origin was kindly provided by professor Tomio Tada. In these studies, employing these cloned cells, the author investigated both proliferation responses of Thl cells in the presence of various concentrations of cytokines, such as IL-2, IL-4 or IL-6 and proliferation of Thl cells to various concentration of mitogens such as PHA, ConA or PWM. In addition, the author also investigated the proliferation response of Th1 cells to the optimal dose of PHA, ConA or PWM in the presence or absence of above mentioned cytokines. It was found that IL-2, IL-4 or IL-6 alone their growth stimulation degree was dependent on cytokine concentration and that PHA, ConA or PWM stimulated Thl cell proliferation and optimal dose of PHA ConA and PWM was 3 g, 4 g and 2 g per ml, respectively. In addition, proliferation response of Th1 cells to ConA or PWM in the presence of IL-2 was significantly enhanced, but the proliferation response to PHA was not increased significantly. However, IL-4 did not significantly modulate mitogen-activated Thl cell proliferation response. Interestingly, IL-6 decreased PHA- or ConA-activated proliferation of Thl cells, but did not change PWM-activated proliferation. Taken together, these studies strongly suggested that IL-2, IL-4 or IL-6 itself clone stimulated the Thl cell proliferation and that PHA, ConA or PWM also stimulated Thl cell proliferation. In addition, these studies also indicated that IL-2 increased ConA- or PWM-activated Thl cell proliferation, but IL6 inhibited PHA- or ConA-activated Th1 cell proliferation and that IL-4 did not significantly change the mitogen-activated Th1 cell proliferation.
