PURPOSE: To evaluate the efficacy of the arterial phase of dynamic spiral CT in the detection of pancreatic adenocarcinoma compared with the late phase. MATERIALS AND METHODS: Two phase spiral CT images of seventeen patients with pathologically proven pancreatic ductal adenocarcinomas were compared retrospectively. CT scans were performed with 5mm collimation at 1:1 pitch table speed. Images of arterial and late phases were obtained at 35 seconds and 180 seconds after initiation of administration of 100mL of contrast material(3mL/sec), respectively. Images of the arterial phase were compared with those of the late phase. RESULTS: Images of the arterial phase showed sufficient contrast between the tumor and adjacent pancreatic parenchyma in 12 cases, insufficient in four cases, and no significant contrast in one case. Images of the late phase showed sufficient contrast in five cases, insufficient in five cases, and no significant contrast in seven cases. Images of the arterial phase was superior to that of the late phase in 12 patients(70.6%). In six of the 12 patients, only the images of the arterial phase showed contrast between the tumor and the adjacent parenchyma. The images of late phase showed only one case of three metastasis detected on the images of the arterial phase. CONCLUSION: The arterial phase of spiral CT is superior to the late phase that is comparable with conventional CT in the detection of pancreatic adenocarcinoma.

Subperiosteal Cortical Defect is a symptomless rarefaction of cortical bone which begins most often on the external surface of the medial and posterior cortical walls of the lower end of the femur in children between the ages of 3 and 6 years. The name of Subperiosteal Cortical Defect was first used by Aegerter who differentiated it from non-osteogenic fibroma. The authors found out 5 positive cases of incidental findings among 62 cases of both knee joint X-ray of which 3 was male and 2 was female. Also we experienced 3 cases which necessiat d a correct diagnosis and differential diagnosis. Because this is a common lesion, it frequently accompanies more serious bone conditions, and because this is self-limited disease, treatment is not necessary. It was emphasized that its nature should be understood by all those dealing with bone disease lest it be overdiagnosed and overtreated.

Weight control diets induce reducing women' bone mineral density (BMD) that has a close relationship to risk in osteoporosis. This study was carried out to identify bone density risk factors affecting women's BMD, and to examine the relationship age, lifestyle and dietary habits for bone health by physical measurement and questionnaies. The subjects of this study were 194 women living on the Seoul area. When the subjects were divided into 4 age groups, BMI was the highest in the 50 years group (24.8) and the lowest in the 20 years group (21.63). Average T-score, which is BMD of forearm bone and calcaneus was the highest in the 40 years (.0.07) and the lowest in the 20 years (.0.59). The rate of eating breakfast was shown significantly higher in the 50 years group than that in the younger group. The frequencies of eating out, fried food intakes, and alcohol drinks were shown significantly different by age (p < 0.01). In conclusion, the risk rate of BMD was high in the 20syears and 50 years groups. It may due to the 20s' weight-control diet. Breakfast eating, exercise, intakes of anchovies, radishes, carrots, zucchinis and tomatoes were significantly important factors to prevent bone density risk.

This study was carried out to compare bone density risk factors affecting women's BMD, and to examine the relationship age, lifestyle and dietary habits for bone health by physical measurement and questionnaires. The subjects of this study were 194 women living in the Seoul area. When the subjects were divided into normal and risk groups, BMD, height, weight, BMI, total body water, soft lean mass, fat free mass, protein, mineral, body-fat of normal group were much higher than those of the risk group. The breakfast eating rate of the normal group was much higher than that of the risk group, walking time was significantly longer and exercise was more (p < 0.05). The normal group had more frequent intakes of tunas, squid, radishes, the green parts of radish, cucumbers, carrots and Iucchinis, tomatoes, and grapes than the risk group (p < 0.01 or p < 0.05). In conclusion, breakfast eating, exercise, intakes of some foods such as anchovies, radishes, carrots, zucchinis and tomatoes were significantly important factor to prevent bone density risk.

Kimura's disease is an important category of reactive lymphadenopathy especially among Asians. It is a chronic inflammatory disorder of unknown etiology and is characterized by angiolymphoid proliferation and eosinophilia. The patient was a 17-year-old man with a 3-year-history of submandibular lymphadenopathy Who was referred to Kyung Hee University Hospital for evaluation of enlarging mass. He had a history of nephrotic syndrome for 7-8 years since 1984. Laboratory findings were not specific except for peripheral blood eosinophilia. The submandibular lymph node showed florid germinal enters, increased postcapillary venules in the paracortex, eosinophilic infiltration, and sclerosis. In this paper, a case of lymphadenopathy of Kimura's disease associated with nephrotic syndrome is reported.

BACKGROUND AND OBJECTIVES: Uvulopalatal flap (UPF), which is a modification of UPPP, is established in the treatment of snoring and obstructive sleep apnea syndrome (OSAS) with reduced velopharyngeal incompetence (VPI) risk. This study was performed to evaluate the subjective outcome of UPF among patients with simple snoring or obstructive sleep apnea. MATERIALS AND METHODS: Twenty patients with OSAS were examined (sixteen male, four female) in a prospective manner. Subjects who underwent UPF have completed pre or post operative (after 3 months) polysomnographic (PSG) studies. The parameters of PSG were apnea index (AI), respiratory disturbance index (RDI), mean SaO2, and lowest SaO2. Questionnaires composed of Eworth sleepiness scale (ESS) and snoring symptoms inventory (SSI) were completed by patients and bed partner before and after the UPF. Statistical analysis was performed using the Wilcoxon signed rank test. RESULTS: Subjective questionnaires indicated statistically significant improvements (SSI ; from 60.9 to 37, ESS ; from 11.6 to 7.4). The AI decreased from 18.6 to 9.3, RDI decreased from 29.8 to 16.6 (p<0.05). CONCLUSION: UPF seems to be more effective in mild OSAS than in moderate and severe OSAS. Long term follow up studies with more patients is deemed necessary.

BACKGROUND: Heart transplantation is considerated for a selected certain group of complicated congenital heart disease in neonates because corrective surgery is very difficult and has high mortality. Precise planning of transplantation is necessary to adequately fit the donor heart to the recipient. MATERIAL AND METHOD: We have performed 4 neonatal pig heart transplantations to test the technical feasibility. Experiment 1: The transplantation was performed using the same technique as the adult heart transplantation. Experiment 2: The transplantation for hypoplastic left heart syndrome was simulated as we reconstructed the whole aortic arch with donor aorta. Experiment 3: The heart transplantation was done with radical pulmonary artery reconstruction. Experiment 4: The experiment was performed for a long term survival. RESULT: Preoperative planning was very important for adequate fitting. All animals could be weaned from cardiopulmonary bypass, however, two animals died due to bleeding at pulmonary artery and left atrium. CONCLUSION: We concluded that the neonatal heart transplantation can be applied in some complicated Further using animal model is mandatory.
