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.

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.

BACKGROUND: It is controversial that an electrocardiography (EEG) is valuable in evaluation of patients with headache. The purpose of this study was to determine whether EEG brain mapping can be a useful indicator for evaluating the analgesic efficacy of treatment on the patient with an occipital headache. METHODS: We did an EEG on 20 patients with occipital headaches at the peri-laser application period. The laser was radiated for 3 minutes a third of the total distance from the external occipital protuberance to the mastoid process on the superior nuchal line. An EEG was taKen before laser radiation as control use, and at 10, 30 and 60 minutes after laser radiation by 32 channel electrodes (international 10 20 system). The EEG mapping was red for the high electric potential and blue for the low electric potential. RESULTS: Compared with control group, the alpha wave increased significantly in parieto-occipital and occipital region at 60 minutes after laser radiation (P < 0.05). DarK red color was increased especially in occipital region at 60 minutes after laser radiation, compared with EEG mapping before laser radiation. Good and Fair improvements were observed in 55% of the patients with occipital headaches. CONCLUSIONS: We conclude that EEG can be a valuable indicator in the evaluation of analgesic efficacy of treatment in the patients suffering from occipital headaches. Pain scores were assessed by the patient with the visual analogue scale (VAS).

Sclerosing stromal tumor (SST) was first delineated as a distinct ovarian sex cord stromal tumor in 1973 by Chalvardjian and Scully. It is a benign neoplasm, distinguished from other ovarian stromal tumors by the production of collagen and a pseudolobular pattern, and it tends to occur in the second and third decades of life in diagnosed patients. We discovered two rare cases of SST in post-menopausal women which are the topic of this report. These case studies are accompanied by a brief review of the literature.

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.
