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.

On the whole, the major impetus for the institutionalization of public hygiene in Korea came from two directions. On one hand, the self-enlightened intellectuals had introduced a variety of Western ideas and theories on public hygiene since the mid-eighteenth century. On the other hand, Japan strongly influenced the modern systems of Korean health care and medical education, especially through Japanese efforts at the sanitary control of infectious diseases such as smallpox and cholera. The institutionalization of Korea's public hygiene in this period corresponded not to the high ideas of the progressive intellectuals but to the larger social and institutional changes caused by the major political events. Ideas of public hygiene were institutionalized as a powerful strategy of linking the imperial capital and colonial domains.

BACKGROUND: It has been suggested that mitral regurgitation(MR) of hypertrophic cardiomyopathy is associated with left ventricular outlet pressure gradient, systolic anterior motion of mitral leaflet, abnormal coaptation of mitral valve, malalignment of papillary muscle and elongation of mitral leaflet. To investigate the relation between the degree of MR and the several causing factors, we reviewed 35 patients with hypertrophic cardiomyopathy. METHOD: 35 patients with hypertrophic cardiomyopathy were classified into a group I(24 patients) without mitral regurgitation and with grade 1 MR or a group II(11 patients) with grade 2 and grade 3 MR. Measurement of mitral leaflet was performed on 2-D echocardiography. Distance between interventricular septum and systolic anterior motion(SAM) of the mitral leaflet was measured on M-mode echocardiography. RESULT: 1) Mitral regurgitation was observed in 22 patients(63%) among 35 patient. 2) Left ventricular outflow pressure gradient was 11+/-10mmHg in group I, 79+/-68mmHg in group II(p<0.05). Interventricular septum-SAM distance was 1.0+/-0.3cm in group I, 0.3+/-0.5cm in group II. 3) Anterior mitral leaflet length was 2.76+/-0.51cm in group V, 2.89+/-0.34cm in group II and posterior mitral leaflet length was 1.71+/-0.43cm in group I, 1.80+/-0.29cm in group II(p>0.05). 4) Mitral annulus circumference was 8.57+/-1.13cm in group I, and 8.58+/-0.92cm in group II(p>0.05). CONCLUSION: There was no correlation between the degree of mitral regurgitation and mitral leaflet length or mitral annulus circumference but, left ventricular outflow pressure gradient and interventricular septum-SAM distance were good correlated with degree of mitral regurgitation.
