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.

In 56 breast cancer tissues (infiltrating ductal carcinoma) with a clinical follow-up period of more than 5 years, positivity of estrogen receptor(ER) by enzyme immunoassay and expressions of bcl-2 and p53 oncoproteins by immunohistochemistry were evaluated. The purposes of this study were to determine prevalence of bcl-2 and p53 in breast cancer, the interrelationship between expression of the proteins and estrogen receptor, correlation between histologic grade and the expression of the tumor-related oncogenes, and to explore the biologic bahavior of breast cancer (lymph node metastasis, recurrence rate, and survival) via expression of bcl-2 and p53. Twelve of 56 (21.4%) carcinomas were bcl-2 positive, and seventeen (30.4%) were p53- positive. Eleven of 12 bcl-2 positive tumors (91.7%) were ER-positive, and bcl-2 expression was significantly associated with ER-positivity(P=0.043). Seven of 36 ER-positive tumors (12.5%) were p53 positive, and p53 expression was inversely associated with ER-positivity(P=0.006) significantly. The bcl-2 protein expression showed a significant relationship to low histologic grade of tumor (P=0.0002), and an almost significant relationship to lower recurrence rate (P=0.09). The p53 protein expression showed a significant relationship to high histologic grade of tumor (P=0.002) and an almost significant relationship to lymph node metastasis (P=0.09). Also an almost inverse relationship between bcl-2 and p53 was demonstrated (P=0.057). The bcl-2 expression had a tendency to be associated with longer patient survival(P= 0.09), but p53 immunoreaction was found not to be associated with shorter patient survival(P=0.16). These results provide further evidence that higher incidence of bcl-2 expression is correlated with higher incidence of ER and lower grade of tumor, while p53 expression is correlated with lower incidence of ER and higher grade of tumor. In conclusion, although the biologic function of bcl-2 protein is not yet well understood in breast cancer, our results suggest that bcl-2 and p53 oncoproteins might play significant roles in estrogen receptor and development of breast cancer. But their prognostic significance could not be determined; our results are 'not significant' but 'almost significant'. Thus, contribution of bcl-2 and p53 immunohistochemical phenotyping of breast cancer with ER to the clinical management need verification in larger series.

The authors report a case of malignant teratoma in a 3-year-old girl who suffered from occipital headache and vomiting for about 2 months. The tumor occupied left cerebellopontine angle resulting in a moderate degree of hydorcephalus. Histologically, the tumor consisted mainly of neuroepithelial tissues showing varying degrees of differentiation, with areas of epidermis, mature fat tissue, connective tissue, gastrointestinal glands and smooth muscle bundles containing ganglions. Also noted are groups pf polygonal or spindle cells representing immature mesodermal tissue. In contrast to two malignant intracranial teratomas previously reported in Korean literatures, this case is characterized by the presence of predominent neuroepithelial components and by uncommon tumor location, the posterior fossa far from middle line of the body.
