The Pleomorphic xanthoastrocytoma(PXA) is considered as a special subgroup of gliomas because of its distinctive characteristics: onset in young subject; predilection for the temopral or parietal lobe and a superficial location; frequent appearance as a yellow encapsulated mass with a grossly visible tumor-associated cyst; marked histological pleomorphism; little or no mitosis and no necrosis; presence of a rich reticulin network; and demonstrable GFAP in many of the fusiform and giant cells; most importantly, the relatively favorable prognosis despite plemorphism and bizzare giant cells in the microscopic picture. The objective of this report is to add one more case of pleomorphic xanthoastrocytoma to the medical literature.

PURPOSE: We studied to evaluate the effect of percutaneous catheter drainage (PCD) in liver abscess. MATERIALS AND METHODS: We retrospectively analyzed clinical data (presence of fever, WBC count), radiological findings (computed tomography, ultrasonography and abscessogram) and correlated them with treatment period. Percutaneous drainage of liver abscess were performed in 19 patients under fluoroscopy guide during recent three years. RESULTS: Eighteen patients (95%) were cured, and one patient underwent surgery because of peritonitis caused by PCD procedure. Average treatment period was 17 days. CONCLUSION: In the treatment of liver abscess, PCD is thought to be safe and effective.

A 63-year-old male who had subtotal gastrectomy for early gastric cancer three months ago underwent Tc-99m bone scintigraphy for the evaluation of skeletal metastases. He had no symptoms such as fever, tenderness, or wound discharge. On physical examination, the surgical scar along the midline of the upper abdomen had keloid formation and there was no radiographic evidence of calcification. Bone scintigraphy (Fig. 1A & 1B) demonstrated an unusual linear increased uptake along the midline of the upper abdomen that corresponded to the skin incision for subtotal gastrectomy. Usually, an incisional scar will not be visualized in Tc-99m methylene diphosphate (MDP) scintigraphy beyond two weeks after surgery.1) Upon reviewing the literature, there were only a few reports where localization of Tc-99m MDP in surgical scars were found two months after surgery.2) It was also reported that a few cases with Tc-99m MDP uptake in the keloid scar developed after surgery. Although there are several potential mechanisms that may explain the uptake of Tc-99m MDP in scar tissue, the primary mechanism in older scars is suggested to be a result of pathological calcification.2) Siddiqui et al3) suggested it could be due to microscopic calcification in small resolving hematomas. However, the primary mechanism in keloid scar is not well-known. We should obtain oblique or lateral views to differentiate the uptake in healing surgical scars from the artifactual uptake.

A 60-year-old male with carcinoma of the prostate and cerebral infarction underwent a Tc-99m MDP bone scintigraphy for the evaluation of skeletal metastases. Bone scintigraphy (Fig. 1) showed multiple areas of increased uptake of Tc-99m MDP in the skull, spine, and ribs representing skeletal metastases. Two different patterns of uptake occurred in the skull region (Fig. 1A-C); one represents bony metastasis and the other represents cerebral infarction. The shape, size, location, intensity, and border of the increased uptake differed between the two lesions. An oval-shaped pattern with smaller size, greater intensity and more sharply defined border in the frontal region was consistent with bony metastasis. A rectangular-shaped pattern with larger size, lesser intensity and relatively indistinct border in the temporo-parieto-occipital region was consistent with cerebral infarction. Increased uptake of bone-seeking radiotracers in cerebral infarction has been reported previously.1-4) A suggested mechanism by which bone-seeking radiotracers accumulate in the necrotizing cerebral tissue is an alteration of the blood-brain barrier induced during cerebral infarction, which results in entry of the radiotracers into the extracellular space of the brain.4) Brain CT (Fig. 2) performed 7 days before and one month after the bone scintigraphy revealed lesions on the right temporo-parieto-occipital region consistent with acute hemorrhagic and chronic cerebral infarction, respectively.

The purpose of this study was to investigate setting and thermal expansion of dental soldering investments. In order to compare expansion rates and to investigate the effect of water/powder ratio on expansion, setting and thermal expansion of four dental soldering investments were measured under three different water/powder ratio conditions: standard, 20% decreased and 20% increased. Setting expansion of investments was measured by use of dialgauge method. Each measurement was started two minutes later from the beginning of spatulation and recorded every one minute for one hour. Thermal expansion of cylindrical test specimens, 10mm diameter, 50mm length, was recorded in a Thermodilatometer at heating rate of 10degrees C per minute from 25degrees C to 700degrees C. The results of this study were obtained as follows: 1. Setting expansion rates under the standard water/power ratio condition were 0.198% in Speed-E, 0.090% in Deguvest, 0.080% in CM and Hi-temp. Setting expansion of Speed-E was significantly different from those of CM, Deguvest and Hi-temp, and setting expansion of Deguvest was significantly different from those of CM and Hi-temp(p<.05). 2. Under the decreased water/powder ratio condition, there was significant increase in setting expansion of 4 dental soldering investments(p<.05). 3. There were no significant differences in setting expansions of investments except Hi-temp between standard and increased water/powder ratio condition(p<.05). 4. Thermal expansion rates under the standard water/powder ratio condition were 1.923% in Deguvest, 1.629% in Speed-E, 1.619% in Hi-temp and 1.580% in CM. No significant difference in thermal expansions under the standard water/powder ratio condition existed only between Speed-E and Hi-temp(p<.05). 5. Under the decreased water/powder ratio condition, there was significant increase in thermal expansion of CM and Deguvest but decrease in thermal expansion of Speed-E(p<.05). 6. Under the increased water/powder ratio condition, there was significant decrease in thermal expansion of CM, Deguvest and Speed-E but decrease in thermal expansion of Hi-temp(p<.05).

PURPOSE: The purposes of this study were to examine the relationships among the sense of control, social support, depression and nursing home adjustment, and to identify the influencing factors of nursing home adjustment in nursing home residents. METHODS: The study design was a cross-sectional descriptive study. Data were collected from May to June of 2010 using structured questionnaires from 212 elderly residents without dementia from 15 nursing homes. RESULTS: The levels of nursing home adjustment depended on the self-rated health, the voluntary institutionalization, and the length of stay. The nursing home adjustment was significantly correlated with a sense of control, social support and depression. The five most influential factors affecting adjustment were self-rated health, placement decision maker, the length of stay, a sense of control and depression, which explained about 51.5% of the variances. CONCLUSION: The findings reflect the importance of voluntary institutionalization, a sense of control, avoiding depressive mood and social support which facilitate residents' adjustment. These results can provide guidance for nursing interventions to facilitate nursing home adjustment.

This study was conducted to investigate the validity of using a cameraphone for a dietary intake survey method. The subjects were 28 female college students. After eating a standard lunch meal which consisted of plain rice, seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi, the quantity of dietary intake, calorie intake & nutrients intake were analyzed by weighed method, diet record method and cameraphone method by dietitian with & without cameraphone analysis training. There were no significant differences in the quantity of 6 foods intake between weighted method and cameraphone method by dietitians with camera phone analysis training. However, the quantity of seaweed soup, bulgogi & cucumber salad intake analyzed by diet record method was significantly lower than the weighed method. And the quantity of seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi intake analyzed by the cameraphone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. There were no significant differences in the calorie intake and nutrients intake between the weighted method and camera phone method by dietitians with camera-phone analysis training. However, protein, calcium, iron, phosphorous, Vitamin A, Vitamin B2, Vitamin E and cholesterol intake analyzed by diet record method was significantly lower than the weighed method. And fat and Vitamin B2 intake analyzed by the camera phone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. Therefore, this study suggests that the use of the camerephone may be a valid and convenient method for evaluating a dietary intake survey. However, systematic and standard education is necessary about the size and volume of dishes and angle of photo for more accurate results.
