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.

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.

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: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.

BACKGROUND: Catheter ablation using radiofrequency energy has been established as the most important mode of treatment in patients with accessory pathway. However the ablation of midseptal accessory pathways had been recognized as being more difficult to ablate than other located pathway because of the low incidence and the difficult localization of ablation site. This paper describes the electrophysiologic characteristics of successfully ablated midseptal accessory pathway using radiofrequency energy. METHOD: Routine electrophysiologic studies were performed in 13 patients with midseptal accessorypathway. Guided by the recording of VA interval, the ablation catheter was positioned in all patients in an area bounded anteriorly by the tip electrode of the His bundle catheter and posteriorly by the coronary sinus ostium. Local electrograms during orthodromic atrioventricular reentrant tachycardia or right ventricular apical pacing were compared for 13 patients with midseptal accessory pathway and consequent 13 patients with posteroseptal accessory pathway. RESULT: 13 patients with midseptal accessory pathway; eight with constant Wolff-Parfinson-White syndrome, one with intermittent Wolff-Parkinson-White syndrome and four with concealed bypass track underwent attempts at ablation of their pathway using radiofrequency energy. 11 accessory pathways were successfully ablated without complication during the firstsession. A second attempt at ablation was made in two patients with success(one; recurred case, the other one; failed case at the first session). In the surface 12-Lead ECG, all eight patientswith constant Wolff-Pakinsin-White syndrome had not shownen Qrs complex at lead 3. Two patient with midseptal accessory pathway had transient left bundle branch block during orthodromic tachycardia. The VA interval during left bundle branch block was not change compared to that during narrow complex tachycardia in both. In all patients with midseptal accessory pathway, the VA interval in his bundle electrogram were almost similar to that in the coronary sinus ostial electrogram, which was not observed in the patients with posteroseptal accessory pathway. CONCLUSION: We suggest that VA interval during orthodromic tachycardia and right ventricular apcial pacing is the most reliable market for identifying midseptal accessory pathway, especially distinguishing from posteroseptal accessory pathway.
