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.

Gaucher's disease is an autosomal recessive genetic disorder of lipid metabolism. A deficiency of beta-glucocerebrosidase causes an accumulation of glucocerebroside in the reticulo-endothelial system and bone marrow. Total or partial splenectomy has been used in case of massive splenomegaly with hypersplenism and/or mechanical pressure symtoms. Partial splenectomy is preferred to prevent susceptibility to overwhelming postsplenectomy sepsis and to delay the massive deposition of glucocerebroside in the liver and bones. We report the case of a 20-year-old woman with Gaucher's disease and who had a splenic embolization 4 years ago. The spleen cross the midline of the abdomen reached to the true pelvis and elevated the left diaphragm. Angiotensin-converting enzyme, acid phophatase and ESR were increased but beta-glucocerebrosidase was normal. Osteosclerotic changes of the distal femur was observed. Hepatomegaly and splenomegaly with mutiple accessory spleens were seen on abdominal CT. On isotope scan for liver and spleen, multiple accessory spleens had isotope uptake, but spleen did not. We noted severe adhesion of spleen to neighboring structure and no viable splenic tissue for preservation. Total splenectomy with preservation of four accessory spleens was performed. We needed multiple transfusion during dissection and bleeding was continuous for 3 days postoperatively. The patient was discharged without problems on the postoperative 15 th day.

Oligmeganephronia is congenital hypoplasia of kidney with renal pathology showing very small number of nephrons with compensatory hypertrophy of the remaining glomeruli. A 7- year-old girl was referred to our nephrology clinic due to hematuria detected on school screening urinalysis and diagnosed as chronic renal failure and oligomeganephronia on renal biopsy. We are reporting the clinical and histomorphometric changes for the four years follow-up with review of literatures.

OBJECTIVES: The aim of this study is to investigate correlation between the location of white matter hyperintensities (WMH) and neurocognitive dysfunction in non-demented Korean vascular depression patients. METHODS: A total of 148 subjects diagnosed with first major depressive episode after the age of 60 were included in this study. Subjects were divided into the vascular depression group (n=83) and the non-vascular depression group (n=65) according to the degree of WMH. The degree and location of WMH on T2-weighted images were measured using the Scheltens scale. In addition, several clinical features, including cognitive functions and depression severities, were evaluated. Correlation analysis was performed for examination of the relationships between the location of WMH and neuropsychological functions. RESULTS: Capsular frontal periventricular hyperintensities showed correlation with poorer performance of the word list memory test, constructional recall test, and trail making test A and B. Lateral ventricular hyperintensities showed correlation with poorer performance of verbal fluency test, word list recognition test, and trail making test B. Deep WMH, especially parietal and occipital lesions, showed an association with poorer performance on trail making test B. In addition, deep WMH, but not periventricular WMH, showed an association with Hamilton Depression Scale score. CONCLUSION: Our results suggest that subjects with vascular depression showed significantly poorer performance on neurocognitive tests than those with non-vascular depression. In addition, WMH, depending on their locations, showed different correlations according to details of cognitive dysfunction and severity of depressive symptoms.
