The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3- dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found . The results were followed,1. The mean occlusal plane angle in cast-mounted articulator was 13.5.(SD+/-5.4).2. The mean occlusal plane angle in cephalogram was 10.4.(SD+/-4.3).3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was 3.3.(SD+/-4.6).According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram.And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

Serous cystadenomas of the pancreas account for approximately a third of pancreatic cystic neoplasms. Their coexistence with a second tumor is extremely rare. We now report a case of a serous microcystic adenoma combined with an intraductal papillary mucinous tumor of the pancreas in a 69-year-old man. Abdominal computed tomography scans demonstrated an incidental cystic mass in the body with cystic dilatation of the duct in the head of the pancreas. Central pancreatectomy with pancreatico-jejunostomy, and cyst excision of the pancreatic head were performed. Histologic examination demonstrated a serous microcystic cystadenoma in the body coexisting with an intraductal papillary mucinous adenoma in the head of the pancreas. This case study highlights the importance of careful intra-operative and pathologic examination for synchronous pancreatic tumors.

Choroidal metastatic carcinoma is very rare. We recently experienced a case of lung adenocarcinoma which presented to the clinic with ocular symptoms. This 57-year-old Korean male patient visited the department of ophthalmology due to decreased visual acuity and pain of the left eye. On MRI scan, a nodule was attached to the retina of the left eyeball. On simple chest radiograph, a large amount of pleural effusion was noted in the left pleural cavity. Emergency enucleation of the left eyeball was done with an impression of malignant melanoma causing an intractable ocular pain. Grossly, the lesion in the eyeball was rising from the choroid. On histologic examination, tumor cells formed many irregular, small gland-like structures. The tumor cells showed alcian blue-positive mucin in the cytoplasm and glandular lumens and were positive for CEA. Chest CT scan was performed postoperatively and showed a huge mass in the left lower lobe and multiple nodular opacities in both lung fields. Bronchoscopic biopsy revealed moderately differentiated adenocarcinoma similar to that of the eyeball.

BACKGROUND: The angiotensin converting enzyme(ACE) is a key component of the renin-angiotensin system thought to be important in the pathogenesis of hypertension and cadiovascular diseases. Deletion polymorphism in the ACE gene may be a risk factor for myocardial infarction. The insertion/deletion(I/D) polymorphism of the ACE detected by PCR analysis appears to be associated with hypertension in Koreans and its nucleotide was subcloned into T-vector and its nucleotide sequences were determined. We also examined an association between hypertension and genetic variance of ACE. METHODS AND RESULTS: We identified the angiotensin I-converting enzyme genotype in 127 hypertensive and 189 normotensive Korean subjects. The distribution of ACE genotype II, ID, DD were 39.2%, 40.2%, 20.6% respectively and the frequency for ACE alleles I and D were 0.593 and 0.407, respecively in all subjects. The frequency of D allele in Korean males is higher than that of Korean females(male; 0.438 : female; 0.267), and the frequency of I allele in Korean females is higher than that of Korean males(female; 0.733 : male; 0.562). Genotype distributions of angiotensin I-converting enzyme genes in Korean normal adult population were different from that of Caucasians(P<0.001). There were no significant differences in genotype frequency between the hypertensive control group(n=127) and the normotensive group(n=189). CONCLUSIONS: We observed significant differences of ACE genotype distribution between the male group and the female group in total(P=0.001) and in hypertensive Korean subjects(P=0.013).

In this study, We have tried to evaluate with a Pulse oximeter the changes of SaO2Pulse, and Temperature in the recovery period. We divided 75 patients into the following 5 groups according to operation sites and anesthetic methods. 1) Lower aMominal operation (Group 1) 2) Upper abdominal operation (Group 2) 3) Head and Neck operation (Group 3) 4) Extremity operation (Group 4) 5) Subarachnoid Block (Group 5) We measured the values preoperatively, on arrival at the recovery room, and at 5 minutes 10 minutes, 20 minutes, and 30 minutes later. The SaO2was decreased in all groups on arrival, significantly in group 2 and 4, but progressively increased toward normal range. The Temperature dropped significantly in groups 2, 4, and 5 on arrival, the pulse was significantly decreased only in group 5. As a result of this study, We recommend supplementel oxygen and thermoregulation for immediate postanesthetic patient care.

PURPOSE: In recent years, colonic diverticular disease has increased rapidly because of high intraluminal pressure in the colon due to the low fiber westernized diet and the increasing number of elderly people. Furthermore, emergency operation is required in many cases. Therefore, the aim of this study is proposed to review the optimal treatment guide. METHODS: This study is a retrospective review of the hospital records of 34 patients who underwent surgical treatment for colonic diverticular diseases at the National Medical Center from March 1992 to July 2003. RESULTS: The patients consisted of 23 males and 11 females, with mean age of 49 years. The lesion sites were cecum (62%), sigmoid colon (20%), ascending colon (9%), transverse colon (6%) and descending colon (3%), in descending orders of frequency. The patients were staged by Thorsen classification at the right colon and by Hinchey classification at the other sites. At the right colon, there were no cases of stage IV and 2 of bleeding. At the transverse colon and left colon, there were 3 cases of stage II, 5 of III, and 2 of IV. For the right colon, all patients underwent one- stage operation. For the other sites, 3 one- stage operations and 7 two- stage operations were performed. Major or minor postoperative complications occurred in 12 patients, including 2 mortality cases. Among them, 2 cases with colocutaneous fistulas might have been prevented if the operation had been made on the basis of stage. CONCLUSION: Because diverticular disease occurs at the various sites of the colon and has potential risk, it is important that patient treatment is based on stage.
