174 patients who visited in the Department of Dentistry, College of Medicine, Yeungnam University from 1983. 7. 15 to 1986. 11. 30 were surveyed on the tendency of patient distribution and the state of Angle's classification. The results were as follows 1. There was increased visiting rate of patient per year. Female outnumbered male by a ratio of 1.3:1. 2. 8-15 age group was 74% in total visiting in the most frequency. The average visiting numbers of each month were higher among the vacation and was about 74% in that period. 3. As showed the living distribution, Nam Go and Su Sung Gu's patients were 53% of the total. 4. As the motive of visiting in Dental Department, patient of 30% in total patients visited for themself to receive orthodontic treatment and other was introduced patients. 5. By classification, Class I malocclusion was 63% in total visiting patient, Class II malocclusion 17%, Class III malocclusion 20%. Crowding among Class I malocclusion was 60%.

Hepatoblastoma (HB) is a rare embryonic malignant tumor of the liver. Most morphological studies on HB have limited to the histological characteristics and only 3 cases of HB have been described in the cytology literature. We present 2 cases of HB occurring in children aged 1 year and 3 years, respectively. The distinctive cytologic features of fine needle aspiration of HB were clusters of tumor cells showing acinar and trabecular pattern, smaller tumor cells with a high nuclear-cytopalsmic ratio and hyperchromatic nuclei having prominent nucleoli, and the presence of extramedullary hematopoiesis and osteoid material. These features were also found in the cell block and the biopsy specimen, and appeared very useful in the differentiation of HB from hepatocellular carcinoma.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acelluair basement membrane material in the lumen, and 3) cells lacking true nuclear molding and having bland chromatin pattern. The mcrphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

Enlargement of the gingival caused by phenytoin. An anticonvulsant used in the treatment of epilepsy, occurs in some of the patients receiving the drug. Its incidence varies from 3 to 62 percent, with the greater frequencies in younger patients. The hyperplasia is usually generalized throughout the mouth, but is more severe tendency in the maxillary and mandibular anterior regions. 18 year old male patient was admitted to our Department of Dentistry with the complaint of generalized painless gingival swelling. After the consult of the N.M. and laboratory study, the gingivectomy and gingivoplasty was performed. The periodontal pack and tin foil was applied on the attached gingival to protect a surgical site and bleeding control. We obtained a good result of improved esthetics and function.

A 25 year and 7 month old man patient who had Angle's class II division 2 malocclusion combined with anterior crowding of upper & lower part was treated by bioprogressive mechanism. After setting out objectives through the use of V. T. O., we programmed a sequence of mechanic. The possible objectives of treatment in the class II division 2 malocclusion can be listed as follows. 1) Relief of crowding & irregularities. 2) Relief of anterior gingival trauma & correction of interincisal inclination. 3) Correction of buccal segment relationship We'd applied the class II intermaxillary elastics, Quad helix, utility arch wire and sectional arch wire in order to achieve anticipated objectives. As compared with pre & post treatment cephalogram, the result accomplished by this mechanics showed to us that interincisal angle was improved and favorable molar relationship was achieved.

Video-assisted thoracic surgery (VATS) is emerging as a viable alternative to thoracotomy when surgical treatment of spontaneous pneumothorax is required. 20 patients with spontaneous pneumothorax underwent bullectomy between July 1995 and May 1996. The patients were divided into two groups : Control group ; the patients who received with mid-axillary approach (n=10), Experimental group ; the patients who received with VATS (n=10). The results were as follows ; 1. The total sex distribution was male predominance (male:female=17:3). Mean age of control group was 29.6+/-9.8 years and experimental group was 27.2+/-11.9 years. 2. The mean period of postoperative chest tube indwelling duration and hospital stay were 3.3+/-0.8 days and 7.9+/-1.2 days in control group and 2.1+/-0.9 days and 5.2+/-3.1 days in experimental group (p=0.005 and p=0.02). 3. The mean time of operation, vital signs and arterial blood gas analysis did not showed any statistical differences between the groups. 4. Percent recovery of tidal volume and forced vital capacity were significantly improved in experimental group comparing with control group (p<0.05). 5. The patients undergoing VATS experienced significantly less postoperative pain and limitation of motion. In conclusion, VATS is safe and offers the potential benefits of shorter postoperative hospital stays and less pain with cosmetic benefits.

From January, 1992 to June, 1996, )7 patients with flail chest were treated at Sonnchunhyang university hospital. 15 patients were managed by internal fixation of fractured ribs, whereas the remaining 22 patients were managed by endotracheal intubation and intermittent positive-pressure ventilation alone. There were no difference between two groups in age, sex, the severity of injury to the chest wall and the nature of associated injuries. Average dur'Btion of assisted ventilation was 5.7 +/-1.7 days in the patients treated by internal fixation versus 8.7 +/-3.3 days In the patients treated by continuous me hanical ventilation. Average stay in the intensive care unit was 8.3 +/-3.9 days for the patients treated by internal fixation, whereas it was 13.2+/-4.1 days in the group treated by continuous mechanical ventilation alone. In the group treated by internal fixation, complications were 3 atelectases(20.0%), 1 pneumonia(6.7%), 2 operative wound problems(12.3%) and 1 barotrauma(6.7%). In the other group, 7 atelectases(31.8%), 4 pneumonitis(18.2%), 2 empyemas(9.1%) and 3 barotraumas(1).6%). The mortality rate was 13.3%(2/15) in the surgically treated patients, whereas it was 22.7%(5122) in the other group. The treatment of flail chest by internal fixation resulted in speedy recovery, decreased complications and mortalities, and better ultimatc cosmetic and functional results.

A 51-year-old male with chronic renal failure had marked swelling and tenderness of the right arm. Venography revealed central vein occlusion involving stenosis of right proximal subclavian vein, right internal jugular vein, and left distal innominate vein, and obstruction of right brachiocephalic vein. Multiple obstruction of these veins was thought to have resulted from repeated subclavian catheterization. Right subclavian-superior vena cava was bypassed with 10 mm Gore-tex vascular graft and then left subclavian vein with 8 mm Gore-tex vascular graft was bypassed to the 10 mm Gore-tex vascular graft. The results were excellent.
