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.

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.

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.

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.

Maxillary lateral incisors usually exhibit a single root with a single canal. However, maxillary lateral incisor teeth with unusual morphology of root canal system are frequently reported. These cases of variable root canal anatomy can be treated well by nonsurgical endodontic methods. A detailed description of root canal morphology is fundamental for successful endodontic treatment. Treatment using an operating microscope, radiographs from different angles, and cone-beam computerized tomography (CBCT) can produce more predictable endodontic outcomes.

BACKGROUNDS/AIMS: Although laparoscopic cholecystectomy is a common and widely accepted technique, the use of prophylactic antibiotics in elective laparoscopic cholecystectomy still remains controversial. The aim of this study is to determine whether prophylactic antibiotics could prevent surgical site infection after elective laparoscopic cholecystectomy and to identify any risk factors for surgical site infection. METHODS: This study included 471 patients undergoing laparoscopic cholecystectomy between January 2009 and May 2012. Period 1 patients (279) received second generation cephalosporin 1 g intravenously after induction of anesthesia, and Period 2 patients (192) were not given prophylactic antibiotics. The characteristics and surgical site infections of the patients were compared and analyzed. RESULTS: The overall rate of surgical site infection was 1.69% for the total of 471 patients. The incidence of surgical site infection was similar for the two Periods: 5 of 279 patients (1.79%) in Period 1, 3 of 192 patients (1.56%) in Period 2 (p=0.973). All of the patients with surgical site infections were well treated under conservative treatments without any sequelae. The preoperative albumin level (p=0.023) contributed to surgical site infection. CONCLUSIONS: Prophylactic antibiotics are not necessary for elective laparoscopic cholecystectomy but patients in poor nutritional state with low albumin level should consider prophylactic antibiotics.

Neuromas are hyperplasia of axons and associated nerve sheath cells. Cutaneous neuromas are uncommon. Three kinds of true neuromas exist in the skin and mucous membranes: traumatic neuromas, solitary palisaded encapsulated neuromas, and multiple mucosal neuromas. Traumatic neuromas are usually solitary, skin-colored or pink, firm papules or nodules at the sites of scars following local trauma. A 2-year-old male patient presented a solitary rice grain sized, skin-colored painful and tender polypoid papule on the left 2nd finger. The lesion was superimposed on a small linear scar. The patient had taken a trauma by a broken piece of glass about one month before the development of the neuroma. We report a case of traumatic neuroma with a review of the literature.

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.
