STUDY DESIGN: Thirty-fiye thoracolumbar and lumbar burst fractures treated with pedicle screw instrumentation were assessed on loss reduction. OBJECTIVE: To compare the mechanical results of simple posterior fixation and posterior fixation with anterior augmentation by anterior interbody fusion, disc space fusion or longer construct. SUMMARY OF BACKGROUND DATA: Althrough the pedicle screw instrumentation provides good mechanical stability, two segment fixation without anterior column augmentation may not be adequate to withstand the repeated axial load. METHODS: Fifteen patients were treated with two segment fixation alone(Group 1), seven with anterior interbody fusion(Group 2), another seven with disc space fusion(Group 3) and remaining six with longer construct involving two segments abode the fracture(Croup 4). Change of anterior body height, upper disc height, lower disc height, kyphotic angle, inter-screw angle and gross screw bend- ing were measured using post-operative and follow-up lateral radiographs. RESULTS: Comparing the two groups(Croup 1 Ys. Group 2, 3, 4), the Group 1 showed definitely more loss of reduction than those groups which had anterior augmentation. But, loss of anterior body height was not significantly different. Comparing the four groups, loss at upper and lower disc height was significantly greater in the Group 1 than the Group 2. Change of kyphotic angle was significantly higher in the Group 1 than the Group 4 and change of inter-screw angle was also higher in the group 1 than every other group. Seyen patients in the Group 1 showed gross screw bending, but none in the Group 2, 3 and 4. All the seven patients with screw bending showed loss of inter-screw angle more than 5 . CONCLUSIONS: These results mean that anterior column augmentation is necessary for the treatment of thoraco-lumbar burst fracture. All the three methods(Group 2,3,4) are effective to prevent excessive loss of correction and screw bending. The best method should be selected considering the characters of each fracture.

It is well known that metastatic bone tumor is very rare below knee and elbow joint. Recently, we experienced two cases of metastatic tumor from kidney and lung to the tibia at Koryo General Hospital.

This study was performed in order to evaluate the sero-epidemiological status of toxoplasmosis in pregnant Korean women. Among 5, 175 sera and 750 amniotic fluid samples obtained from pregnant women, 41 serum samples (0.79%) and 10 (1.33%) amniotic fluid samples tested positive for IgG antibodies by ELISA. Fifty one cases showing a score more than 0.25 on ELISA were tested for PCR reaction against the SAG1 gene. Only one case of the 51 ELISA positive cases exhibited a positive reaction on all tests. This case had a history of acute nephropyelitis during early pregnancy, but fortunately, had delivered a phenotypically healthy baby. In this study, the seroprevalence of toxoplasmosis in pregnant women was found to be comparatively low, consistent with previous reports from Korea. However our trials, performed with a variety of diagnostic tools, were considered to be useful for the precise diagnosis of congenital toxoplasmosis.

An unequivocal diagnosis of mesothelioma during life, on the basis of limited biopsy tissue or cytological specimens, is frequently difficult and requires distinction from inflammatory mesothelial hyperplasia on the one hand and secondary neoplasms, especially adenocarcinoma on the other. Although some studies have produced conflicting results, it is generally believed that immunohistochemical methods can aid in this distinction. To obtain comparable and reproducible results, 23 metastatic carcinoma of the pleura and 2 unequivocal malignant epiehtlial mesotheliomas were studied by the peroxidase-antiperoxedase method on paraffin-embedded cell blocks, and commercially available antibodies to carcinoembryonic antigen (CEA), keratin and epithelial membrane antigen (EMA) were used. Nineteen metastaic adenocarcinoma (73%) and two mesotheliomas (100%) reacted with keratin and EMA antibodies. Nineteen matastatic adenocarcinomas (73%) reacted with EMA antibodies. Nineteen metastatic adenocarcinoma (73%) reacted with CEA antibody; no mesotheliomas stained for CEA. Two cases of reactive mesothlial hyperplasia showed positive for keratin, but negative reaction for EMA and CEA. Noen of the antibodies used in this study was specific for mesothelioma, but CEA was found to be the most useful marker for differentiating between mesothelioma and metastatic carcinoma.

Favre-Racouchot syndrome(nodular elastosis with cysts and comedones) is a peculiar complication of solar elastosis in which comedones, follicular cysts, and nodules of altered elastic tissue occur mainly sround the orbits, on the cheeks, on snd around the nose, and oceasionally in other exposed areas, but sornetimes on the neck or behind the ears. We present a typical case of the Favre-Racouchot syndrome in a 66 year old man with maxillary cancer. The patient had numerous yellowish cysts and black topped comedones located on the forehead, around the orbits and the nose, on the neck, and also behind the ears of 5 years duration. The histopathology of the lesion showed dilated pilosebaceous openings and epitheliaI lined cysts filled with layered keratin in addition to pronounced solar elastosis.
