Primary ovarian transitional cell carcinoma(TCC) is a recently described, distinct subtype of ovarian carcinoma resembling TCC of the urinary bladder. TCC differs from malignant Brenner tumor(MBT) by absence of benign or proliferative Brenner component and prominent stromal calcification. TCC also represents a high-stage tumor with more aggressive biologic behavior than MBT, but it has a relatively favorable response to chemotherapy. TCC may arise from the pluripotential surface epithelium of the ovary or from the cells with urothelial differentiation, rather than from a benign or proliferative Brenner tumor precursors. We report a case of pure form of primary TCC presenting as a left ovarian mass in 45-year-old woman.

Although most of the patients with endobronchial tuberculosis have some degree of bronchial stenosis, more aggressive treatment is needed to restore the patency of the involved tracheobronchial tree for some patients not responding well to antituberculous chemotherapy combined with steroids. In our first case, we resected stenotic trachea in a 42 years old women who showed overgrowing granulation tissue through the modified Gianturco stent wire which was previously inserted and anastomosed end to end. Another case was a 37 years old male with left main bronchial restenosis complicated after inserting a Strecker stent and sleeve left upper lobectomy was performed.

The mesenchymal chondrosarcoma of the orbit is so rare that only a few cases have been reported in Korea and world-wide. We experienced that a patient whose complaints were proptosis and diplopia caused by orbital tumor. After tumor removal, it was histologically diagnosed as mesenchymal chondrosarcoma. So we report a case of mesenchymal chonrosarcoma of the orbit with a review of the literature.

OBJECTIVE: The aim of this study was to test the psychometric properties of Korean version of 10 items of Drug Attitude Inventory (KDAI-10). METHODS: A total of 157 stabilized schizophrenic patients were entered into the study after completion of screening tests. They completed the KDAI-10. And then they were interviewed with various scales such as Subjective Response Scale (SRS), Positive and Negative Syndrome Scale (PANSS), Extrapyramidal Side Effects Rating Scale (ESRS), and Global Assessment of Functioning (GAF). Correlations of KDAI-10 with these scales were tested. RESULTS: The Cronbach's alpha used to measure the internal consistency of the scale, was high (0.83). Principal component analysis with varimax rotation produced 2 factors, which explained 50.37% of the total variances. The First factor including 6 items was the positive subjective feelings and the second factor including 4 items was the negative subjective feelings, which were identical to the original authors'. Individual item correlations with total scores were all statistically significant (r=0.48-0.72, p<.001). And correlations of KDAI-10 with SRS, PANSS, ESRS and GAF showed that they were significantly correlated. CONCLUSION: Although the results were not quite satisfactory, KDAI-10 was demonstrated to have good reliability and construct validity.

PURPOSE: Several studies suggest that tumor angiogenesis is a significant prognostic factor in carcinoma of the breast, lung, prostate, oral cavity, and colon. We assessed whether intensity of tumor angiogenesis, as measured by microvessel counts in histologic sections, correlates with prognosis in patients with stage III gastric cancer. MATERIALS AND METHODS: Paraffin-embedded sections from 49 patients (23 stage IIla, 26 stage IIIb) with primary gastric cancer that had been completely removed were analyzed for angiogenesis. Vessels were stained with anti-factor VIII polyclonal antibody, and areas with the most discrete microvessels were counted in a 200X field. RESULTS: Patients with stage IIIa gastric cancer had fewer microvessels than those with stage IIIb gastric cancer (32.8+-14.5 vs. 40.3+-16.1, P=0.106). The mean microvessel count from patients who were alive were significantly lower than that from patients who had died at the time of follow-up (24.8+-10.0 vs. 42.9+- 14.5, P=O.OOO). The 5-year survival rate of patients with count less than 33 microvessels was higher than that of patients with count more than 33 microvessels (59.9% vs. 11.6%, P= 0.000). On multivariate analysis by Cox proportional hazards model, the microvessel count was a significant prognostic factor of stage III gastric cancer. CONCLUSION: Tumor angiogenesis assessed by microvessel count may be a significant prognostic factor of stage III gastric cancer and may prove valuable in selecting patients with stage III gastric cancer for aggressive adjuvant therapy and closer postoperative follow-up.

Exposing sound structure of a subgingivally fractured tooth using orthodontic extrusion is considered to be a conservative way to re-establish biologic width without sacrificing esthetics or jeopardizing periodontal support of neighboring teeth. When a misaligned tooth is traumatically involved, a more comprehensive approach combining tooth extrusion and re-alignment may be necessary for a successful restorative outcome. This case report describes a successful esthetic management of a patient with complicated crown-root fracture on the maxillary right central incisor and pre-existing malocclusion in the maxillary anterior region. Forced eruption along with re-alignment of teeth by orthodontic movement seems to allow re-positioning of the fracture line to a favorable position and correction of crowding, providing a better esthetic result.

Between January 1986 and December 1995, 24 patients were treated surgically for thymoma. There were 17 males and 7 females, and their ages ranged from 23 to 69 years old and mean age was 49 years. Thymomas were associated with fourteen my asthenia gravis, and classified histologically as lymphocytic in 12 patients, mixed in 8, epithelial in 4, and classified clinically as stage I in 11, stage II in 4, stage III in 8 and stage VI in 1 patient. Eleven patients with non-invasive thymoma had received surgical resection, and 10 out of 13 patients with invasive thymoma were able to undergo complete resection. A partial resection or tissue biopsy followed by radiation or chemotherapy was done with the remaining three patients. Three died, four had improvement of symptom, two had relapse and fifteen had no symptom during follow up ranged from 25 days to 60 months. In fourteen cases of thymoma with myasthenia gravis, one died due to myasthenic crisis, two showed symptom aggravation, six had less medical treatment and five patients had medical treatment as same as dosage received preoperatively.

Three cases of synchronous carcinomas of endometrium-fallopian tube, endometrium-cervix and endometrium-ovary are reported. Case 1 is endometrial endometrioid adenocarcinoma with FIGO stageIb, Grade 2 and tubal serous adenocarcinoma with FIGO stage Ib, Grade 2. Case 2 is endometrial serous carcinoma with FIGO stage Ilb and squamous cell carcinoma with FIGO stage Ial. Case 3 is endometrial endometrioid adenocarcinoma with FIGO stage Ia, Grade 1 and ovarian mucinous adenocarcinoma with FIGO stage IIIa, Grade 2. There is much confroversy with respect to staging and management of such cases since these tumors may represent either two synchronously occuring primaries or single primary with metastases. It is suggested that when each tumor is different histological subtype the tumors may be considered as two separate primaries and treatment may be less aggressive. It may be a favorable prognosis. The authors present three cases of synchronous carcinomas with a review of literature.

OBJECTIVES: The purpose of this study was to evaluate the proximity of the mandibular molar apex to the buccal bone surface in order to provide anatomic information for apical surgery. MATERIALS AND METHODS: Cone-beam computed tomography (CBCT) images of 127 mandibular first molars and 153 mandibular second molars were analyzed from 160 patients' records. The distance was measured from the buccal bone surface to the root apex and the apical 3.0 mm on the cross-sectional view of CBCT. RESULTS: The second molar apex and apical 3 mm were located significantly deeper relative to the buccal bone surface compared with the first molar (p < 0.01). For the mandibular second molars, the distance from the buccal bone surface to the root apex was significantly shorter in patients over 70 years of age (p < 0.05). Furthermore, this distance was significantly shorter when the first molar was missing compared to nonmissing cases (p < 0.05). For the mandibular first molars, the distance to the distal root apex of one distal-rooted tooth was significantly greater than the distance to the disto-buccal root apex (p < 0.01). In mandibular second molar, the distance to the apex of C-shaped roots was significantly greater than the distance to the mesial root apex of non-C-shaped roots (p < 0.01). CONCLUSIONS: For apical surgery in mandibular molars, the distance from the buccal bone surface to the apex and apical 3 mm is significantly affected by the location, patient age, an adjacent missing anterior tooth, and root configuration.
