The endoscopic fine needle aspiration cytology may add to the diagnostic accuracy of endoscopic biopsy and brush cytology. It is also of particular value in submucosal, infiltrative and ulceronecrotic tumors. Endoscopic fine needle aspiration cytology was done with sclerotherapy needle(23 gauge) in. the 17 patients with submucosal tumor(18 cases), extrinsic compression(2 cases), infiltrative gastric cancer(one case) and cancer of the ampulla of Vater(one case) on the upper gastrointestinal endoscopy. Endoscopic fine needle aspiration cytology established the diagnosis in 6 cases(submucosal tumor of the stomach; 2 cases, submucosal tumor of the duodenum; one case, extrinsic mass of the duodenum; one case, infiltrative cancer of the stomach; one case, and the cancer of ampulla of Vater; one case) of 17 cases. There were negative results for malignancy in 7 cases and material insufficiency in 4 cases. Five cases of the positive results with endoscopic fine needle aspiration cytology were not diagnosed with endoscopic forceps biopsies. There was no complication. We conclude that endoscopic fine needle aspiration cytology is a simple and safe technique and is of particular value in submucosal tumor, extrinsic compression of the upper gastrointestinal tract by tumor, and infiltrative gastric cancer.

PURPOSE: The objective of this study was to evaluate and compare the accuracy of impression body taking by the closed and the open tray impression technique with 3 types of impression tray. Individual tray, metal stock tray and polycarbonate tray were used. MATERIALS AND METHODS: Nine closed tray impressions were taken by individual tray, metal stock tray and polycarbonate stock tray, respectively with polyether impression material. 9 open tray impressions were also acquired by same manner. Precision analysis on the master models was performed by attaching the reference frameworks with alternate single screws and measuring the vertical fit discrepancy of respective analogues in working cast with a stereo microscope. Data were analyzed by 1 way ANOVA and independent t-test. RESULTS: The average fit accuracy of impression bodies was calculated. With the closed tray impression technique, there were significant statistical differences in vertical fit discrepancy according to the types of tray. The individual tray group showed the lowest value and the polycarbonate stock tray group represented the highest. With the open tray impression technique, there was no significant difference in vertical fit discrepancy. Significant statistical difference in vertical fit discrepancy was found between the open and the closed impression technique with the polycarbonate stock tray. CONCLUSION: From the results above, more precise impressions could be acquired by the rigid individual tray compared with the polycarbonate stock tray. It was hard to get consistent accuracy impressions by the closed tray impression technique with polycarbonate stock trays.

Acute changes of the bilateral basal ganglia shown in the brain MRI a diabetic uremic patient have been rarely reported. We report a 52-year-old diabetic uremic patient who had neurological disturbances. At admission, axial diffusion-weighted images and T2-weighted images showed high signal intensities in the bilateral basal ganglia, and axial T1-weighted images visualized low signal intensities in same area. The underlying mechanism may be associated with metabolic as well as vascular factors.

BACKGROUND: Anesthesia and surgery may exacerbate liver function in patients with pre-existing liver disease so it is important to choose less hepatotoxic anesthetics in patients with chronic liver disease. METHODS: This study was designed to examine the postoperative liver function test in 150 patients after hepatectomy with portal triad clamping through retrospective chart review. Patients were divided into an isoflurane group (group I, n = 56) and a propofol group (group P, n = 57) by used anesthetics for maintaining anesthesia. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase, alkaline phosphatase, total bilirubin, albumin, and prothrombin time were checked at preoperation, and postoperatively at 1, 3, 7 and 14 days in the two groups. Indocyanine retention rate (ICG-R15) was measured at preoperation, and postoperatively at 1 and 7 days. RESULTS: AST values increased postoperatively at 1, 3, 7, and 14 days compared with preoperation. ALT values increased postoperatively at 1, 3 and 7 days compared with preoperation and there was difference between group I (443.8 +/- 52.1 U/L) and group P (202.7 +/- 24.7 U/L) at postoperative 1 day. Other values had no significant difference between the two groups. CONCLUSIONS: Though it might need a well controlled study to find the differences in effect between isoflurane and propofol on the postoperative liver function test, we concluded that total intravenous anesthesia using propofol is also one of the safest anesthetic methods for hepatic resection with minimal hepatotoxicity.

BACKGROUND: To collect high concentration of granulocytes for transfusion to neutropenic cancer patients with infections, we investigated the effect of G-CSF or dexamethasone as granulocyte mobilizers and 10% pentastarch (PS) as the sedimentation agent in granulocyte collection by leukapheresis. Subsequently, the therapeutic effect of the granulocyte transfusions was assessed. METHODS: Forty five leukapheresis were performed with CS-3000Plus (Baxter, Deerfield, IL, USA) using 10% pentastarch. The donors were classified into three groups according to their premedication drugs and the interface detector offset; group 1 used dexamethasone with offset 15 (n=16), group 2 used dexamethasone with offset 33 (n=16), and group 3 used G-CSF with offset 33 (n=10). We compared total collected granulocyte counts and granulocyte collection efficiency (GCE). RESULTS: The mean counts of total granulocytes collected and GCE were as follows; 0.9 0.5 x 1010 and 31.6 14.3% in group 1, 1.3 0.6 x 1010 and 39.0 14.2% in group 2, and 1.6 0.9 x 1010 and 63.9 32.2% in group 3, respectively. The counts of granulocytes collected in group 3 was significantly higher than that in group 1 (P<0.05). The GCE of group 3 was significantly higher than that of group 1 and group 2 (P<0.05). Sixteen granulocyte transfusions were performed to 11 patients. We observed successful therapeutic effects in 10 out of 16 transfusions (63%). CONCLUSIONS: G-CSF indicates greater potency than dexamethasone although its high cost is limitation of routine use as mobilizing agents and PS was an excellent red cell sedimenting agent in granulocyte collection. Large volume granulocyte transfusions allow high therapeutic effects in neutropenic patients with marrows of sufficient regenerating capacity.

BACKGROUND: Acute myocardial infarction (MI) is a life-threatening disease and surgical revascularization plays a major role in selected cases. The purpose of this study is to evaluate the left ventricular contractility improvement by examining the wall motion score index (WMSI) and left ventricular ejection fraction (LVEF) in patients who underwent surgical revascularization under diagnosis of acute MI. MATERIAL AND METHOD: From January, 2001 to December, 2004, 149 patients who underwent coronary artery bypass surgery within 2 weeks of acute MI were included. We evaluated pre- and postoperative left ventricular contractility by measuring WMSI and LVEF and examined the associating factors. RESULT: WMSI decreased from 1.54+/-4.30 to 1.43+/-0.40 (p<0.001) and LVEF increased from 48.1+/-12.2% to 49.7+/-12.3% after surgery (p=0.009). Off-pump technique, non-Q wave, anterior MI, and surgery within 7 days after MI were favorable factors for LVEF improvement (p=0.046, p=0.006, p=0.003, p= 0.005, respectively). Conversely, aforementioned factors were irrelevant with WMSI improvement. For triple vessel disease, complete revascularization was favorable factor for WMSI improvement (p<0.001). CONCLUSION: Coronary artery bypass surgery can improve WMSI and LVEF in patients with acute MI. In case of anterior MI with non-Q wave, early surgical revascularization within 7 days may be most beneficial in LVEF improvement. Regarding WMSI, complete revascularization may be essential.

The odontogenic keratocyst (OKC) is a developmental odontogenic cyst typically occurring in the jaws. Since the first description of OKC was published in 1956, the lesion has been of particular interest because of its specific histopathologic features, high recurrence rate, and aggressive behavior. Recurrences most commonly arise within bone at the site of the original cyst. However, as lining cells may find their way into surrounding tissues either from implantation during surgery or from cortical perforation recurrences may arise at a distance from the original cyst. Here, we report a rare case of recurrent OKC which was first developed in mandible and recurred within the masticatory space.
