The purposes of operative treatment in unstable thoracolumbar and lumbar spine fractures are anatomical reduction and stabilization of the fractures and thus promote neurological recovery and early rehabilitation. To achieve these goals, complete preoperative assessment and recognition of the fracture pattern is necessary in addition to good surgical technique. The authors analyzed 47 cases of thoracolumbar and lumbar spine fractures operated from Jan. 1989 to Dec. 1991 at the Department of Orthopaedic Surgery, National Medical Center. All cases were classified according to Denis classification and in deciding the appropriate surgical approach, fracture type, stability, neurologic status and degree of deformity were all considered. Anterior approaches were performed in 23 cases of burst fracture and 3 cases of fracture-dislocation, and posterior approaches were performed in 1 case of compression fracture, 7 cases of burst fracture, 4 cases of seat-belt type injury and 5 cases of fracture-dislocation, In 3 cases of burst fracture and 1 case of fracture-dislocation, both anterior and posterior approaches were combined. With the analysis of postoperative changes in sagittal and coronal angle, translation and degree of rotation, we evaluated the results of operative reduction in terms of restoring normal anatomical configuration of injured spinal segments. So we tried to find the attributing factors in the operative reduction of the thoracolumbar and lumbar spine fractures and suggest the proper surgical approach that provides better reduction and stabilization.

PURPOSE: The Swedish Interactive Thresholding Algorithm (SITA) strategies is a new diagnostic tool of Humphrey automatic perimetry and has been reported to reduce testing time without loss of useful diagnostic information. To test the usefulness of this new diagnostic method, we compared the SITA and full threshold diagnostic method, which had been used previously. METHODS: Forty six patients (46 eyes) who were followed up for glucoma or ocular hypertension were in this study. Autoperimetry was performed using both SITA and full threshold strategies. RESULTS: The SITA showed shorter testing time (7.74+/-1.25 min) than the full threshold (14.4+2.43 min). There were significant differences between the full threshold MD (-8.06+8.11 dB) and SITA MD (-7.45 +/-8.32 dB), as well as full threshold PSD (4.47+/-2.50 dB) and SITA PSD (3.67+/-2.56 dB), when compared with data of greater than -12 dB MD respectively(p<0.05). Two cases showed changed diagnosis in GHT. CONCLUSIONS: SITA is a good test method with short test time. However, changing from full threshold to the SITA method should be reconsidered due to variation in the amount of field defect depending on the damage progression and the possibility of changes in diagnosis.

Endodermal sinus tumor of the mediastinum is a very rare malignant tumor, usually affecting young adolescents, and its histologic findings are characteristic as that of gonadal germ cell origin. We describe the cytologic finding of fine needle aspiration of mediastinal endodermal sinus tumor in a 19-year-old male patient, comparing with tissue section. The tumor cells in smears were usually in tight clusters with large overlapping cells, which were arranged in a papillary or microacinar pattern, suggesting carcinoma. The tumor cells were large, round or oval with a small amount of cytoplasm which was occasionally vacuolated and had indistinct border. The nuclei were large, pleomorphic, and vesicular with large promi- nent nucleoli. The tissue sections showed typical findings of endodermal sinus tumor. Careful correlation of cytological findings and the serum alpha-fetoprotein level would be helpful to confirm the diagnosis.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.

The peripheral vascular occlusion in the diabetes was studied in fifty-nine male and forty-six female diabetic patients by means of doppler flow meter performed on the dorsalis pedis arteries & post. tibial arteries of the both lower limbs. Patients were divided into two groups, one with occlusion and the other without occlusion. Various predisposing factors causing peripheral vascular occlusions were examined. The results are summerized as follows: 1. Peripheral vascular occlusions were more prevalent in male than in female (male: 25.4%, female: 17.4%). 2. In male patients age, plasma cholesterol level & smoking were statically significant among the various predisposing factors between occlusion & nonocclusion groups. 3. In female patients, duration of diabetes mellitus and the sugar levels of fasting blood and post prandial 2 hours were statiscally significant.
