Abdominal cystic lymphangioma is a rare congenital malformation of lymphatics. Prognosis is excellent with exact diagnosis and complete surgical excision. The aughors analysed 10 US scans and 9 CT scans of surgically proven cystic lymphangiom for the last 5 years. US scan showed it as a septated cystic mass and 2 cases showed fluid-fluid level. CT scan showed a huge unilocular or multilocular density mass with uniformly thickened septae. A huge unilocular or multilocular cystic mass with uniformly thickened septae could suggest cystic lymphangioma would be differentiated from the other cystic masse.

PURPOSE: To analyze the dynamic MR imaging of breast fibroadenoma according to the histologic type for differentiation from breast carcinoma. MATERIALS AND METHODS: Dynamic MR images of 26 lesions from 22 breasts in 19 patients showing atypical clinical features or film mammogram and ultrasound manifestations were performed. We analyzed the speed and the maximal amount of contrast enhancement and the patterns, such as shape, border, and internal signal intensity, among the histologic types during five minutes after contrast injection. RESULTS: The speed and maximal amount of contrast enhancement of fibroadenoma were in descending order of myxoid, sclerotic, glandular, and calcified types. Among these, the value of maximal amount of contrast enhancement of myxoid and sclerotic type were more than 700 NU, but only myxoid type was enhanced more than 700NU within the first 1 minute after contrast injection, similar to the findings of carcinoma. In general, fibroadenoma showed the tendency of smooth surface(69%), well-defined border(88%) with safety rim, and internal homogeneous signal intensity(65%). However, sclerotic type of fibroadenoma had relatively high incidence of heterogeneous internal signal intensity(78%) after Gd-DTPA injection. CONCLUSION: Dynamic MR imaging of atypical breast fibroadenoma mimicking breast malignancy was very useful in differentiation it from carcinoma and had the benefit of classifying fibroadenoma according to its histologic types.

To evaluate the effect of low lactose special formula (MF-1) for the treatment of acute diarrhea, we studied thirty nine infants who were admitted with acute diarrhea to the Department of Pediatics, Yeungnam University Hospital. 39 infants of under 6 months of age who had been fed on formula feeds were randomly allocated to receive either a diluted regular formula milk or a low lactose special formula. Each infant received intravenous rehydration during fasting for 6-12 hou s. Group 1 (n=15) was fed half strength of regular. formula (80-100cc/kg/day) for the first 24 hours, three quarters strength formula (100-120cc/ kg/day) for the next 24 hours, and continued feeding with the full strength regular formula milk. Group 2 (n= 24), who fed the same amount of milk as Group 1, continued feeding with the full strength low lactose special formula from the start of feeding. Male to female sex ratio was 1.6 to 1. The characteristics of infants on admission were comparable in the age, the duration of diarrhea and the stool frequency before admission, the degree of dehydration. There were no significant differences in the duration of hospitalization, changes in stool weight and stool frequency after admission between two groups.(p>0.05) The Body weight and skin fold thickness were increased in group 2 who fed low lactose formula, but those who fed diluted regular formula showed reduction of body weight and skin fold thickness (64.251.48 vs -11.452.2g, 0.60.8mm vs -0.10.3mm

PURPOSE: To assess relative diagnostic value of Ga-67 planar, Ga-67 SPECT, and CT images for detection of head and neck tumors and cervical lymph node metastasis. MATERIALS AND METHODS: Thirty eight patients of pathologically proven head and neck tumors including squamous cell carcinomas(n=32), malignant lymphomas(n=3), undifferentiated carcinomas(n=2), adenocarcinomas(n=l) were enrolled in this study. Ga-67 planar and SPECT images were obtained with intravenous injection of 5mCi of Ga-67 citrate. On the basis of 30 and 20 mm in the greatest diameter of cervical lymph nodes, we compared lesion detectability of Ga-67 planar, SPECT, and CT. RESULTS: Thirty eight cases of head and neck tumors were detected in 29 cases(76.3%) with Ga-67 planar image, 37 cases(97.3%) with Ga-67 SPECT, and 32 cases(84.2%) with CT. 25 of 32 squamous cell carcinomas were positive with Ga-67 planar image and all of 32 cases with Ga-67 SPECT. Both of two undifferentiated carcinomas were positive with Ga-67 planar and SPECT images. Two of three malignant lymphomas were positive with Ga-67 planar image and all of three with Ga-67 SPECT. Eight of nine tumors were negative with Ga-67 planar image and those were less than 30ram. One case of adenocarcinoma was negative with Ga-67 planar and SPECT images. Seven of nine lymph nodes greater than 30mm were positive with Ga-67 planar image and all of nine with Ga-67 SPECT. On the basis of 20mm in greatest diameter, 16 of 21 lymph nodes greater than 20 mm were positive with Ga-67 planar and SPECT images. CONCLUSION: CT providing better resolution than Ga-67 scan permitted analysis of size and location of metastatic cervical nodes, however primary tumors of oral cavity, vocal cord, and nasopharynx were often not detected on CT when metallic and motion artifacts were present, where Ga-67 SPECT was useful. Ga-67 SPECT enabled better anatomical localization than Ga-67 planar image and was useful in detection of lymph nodes greater than 30 mm.

PURPOSE: This study was conducted to develop an integrated undergraduate course including a PBL based on a blended learning strategy, and evaluate learners' responses. METHODS: The learning contents of cardiovascular, respiratory, and musculoskeletal medical systems, and nursing diagnoses of 'activity and rest' domain (NANADA's classification II, 2005) were analyzed. Six clinical scenarios with the clients in different life cycles were developed for PBL. Classical lecture and group presentation with on-line self learning were implemented in addition to PBL. The developed course was implemented on 84 junior nursing students in a university for 7 weeks with 5 hours per day, two days per week. Students were asked to complete structured questionnaires including problem solving, critical thinking, and nursing diagnosis differentiation abilities. RESULTS: Learner's evaluation was positive in problem solving skills and in the differentiation ability of nursing diagnoses relevant to an 'activity and rest' functional health pattern. CONCLUSION: Development and implementation of integrated courses based on a blended learning method need to be continued to enhance students' thinking and self-directed learning abilities. Supporting strategies for individual learners should be added for successful blended learning such as individual on-line feedback and consideration of individual learning outcomes.

BACKGROUNDS: The first step for the recovery of alcoholics is the formation of true insight which enables them to admit that they are alcoholic. This study was designed to analyze the changes in insight status by treatment programs. METHOD: The subjects were 214 alcohol dependents who participated in the insight-oriented treatment programs for at least 1 week. Their insight status were measured through HAIS before and after treatment. RESULTS: Of 214 subjects, 83 (38.8%) were in poor-, 103 (48.1%) in fair-, and 28 (13.1%) in good-insight before treatment, and 56 (26.2%) in poor-, 97 (45.3%) in fair-, and 61 (28.5%) in good-insight after treatment. Mean HAIS scores of the subjects were 5.35 (SD=8.33) before treatment and significantly increased to 9.00 (SD=8.04) after treatment. The magnitude of insight-improvement was negatively correlated with the HAIS scores before treatment in poor-insight group and positively correlated with the duration of participation in treatment in fair-insight group. CONCLUSION: We confirmed the fact that the insight status of patients could be improved by treatment. It was also suggested that the therapeutic strategy needed an individual approach according to the insight state of a patient.

OBJECTIVES: The purpose of this study was to evaluate the performance of half-dose chest CT using an iterative reconstruction technique in patients with lung malignancies. METHODS: The Dual-source CT scans were obtained and half-dose datasets were reconstructed with 5 different strengths in 38 adults with lung malignancies. Two radiologists graded subjective image quality; noise, contrast and sharpness at the central/peripheral lung, mediastinum and chest wall of the reconstructed half-dose images, compared with those of standard-dose images, using a three-point scale. A lesion assessment; lesion conspicuity and diagnostic confidence, was also performed. The quantitative image noises; contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR) were measured and compared with those of standard-dose images. RESULTS: The subjective image noise in the half-dose images was less than that of the standard-dose images. The contrast in strengths 2 to 5 was superior, the sharpness of the lung parenchyma in strengths 3 to 5 was inferior, and the CNR/SNR in all strengths were higher than those of standard-dose images (P < 0.05). The improvement of subjective image noise and contrast, the decrease in sharpness, were correlated with strength level (P < 0.05). The lesion conspicuity in half-dose images of strengths 4 and 5 was decreased. The diagnostic confidence of the half-dose images of all strengths was comparable to that of the standard-dose images (P < 0.05). CONCLUSIONS: Half-dose chest CT images using an iterative reconstruction technique show decreased image noise, increased contrast, and diagnostic confidence comparable to standard-dose images. Images reconstructed with strength 2 and 3 appear to be the optimal choice in clinical practice.

OBJECTIVES: This study aims to investigate the variables predicting violent behavior in schizophrenic patients. METHODS: Subjects were 65 schizophrenic patients diagnosed according to DSM-IV. Schizophrenic symptom and the insight of patients were evaluated with the Postive and Negative Syndrome Scale (PANSS) and the Scale of Unawareness of Mental Disorder (SUMD). Violent behaviors were evaluated with the Modified Overt Aggression Scale (MOAS). The State Trait Anger Expression Inventory (STAXI) and the Symptom Checklist-90-Reversion (SCL-90-R) self-reported measures were used for the evaluation of anger state & trait, and general psychopathology. Statistic method used in analized variables were stepwise multiple regression and discriminant analysis as well as t-test. RESULTS: Anger out style, hostility and trait anger variables were extracted as the significant predictors in stepwise multiple regression (37%). Emotion and attitude factors related to anger were more powerful predictor than symptom factors. These three variables could discriminate between violent group and nonviolent group in 72.4%. CONCLUSION: Violent behavior of schizophrenic patients could be predicted more accurately by stable factors such as attitude and emotion related to anger than by symptom factors.

Traumatic bone cyst is a pathologic cavity that is not lined with epithelium. It is, therefore, not a true cyst. It may be a normal variant rather than a disease process. The etiology of the condition is unknown. This condition is occured widely ranging ages(2 to 75years), however, most are found during the second decade of life. Radiographically, this condition is radiolucent lesion with well-defined outline, scalloping of superior margins. Cyst enucleation and curettage is the treatment of choice. The authors compared and analyzed the clinicoradiologic features of the five cases of traumatic bone cyst, diagnosed at the Dental college hospital in Chosun University, Kwangju, Korea. The five cases were shown the follwed results; 1. 3cases occured in second decade of life and no significant sex differences (M:F, 2:3) All cases occurred in mandible. 2. Two patients complained symptoms, but three cases had no symptom with encountering during routine examination. 3. In 3 of 5cases, teeth vitality existed except one tooth and no checking of teeth vitality in two cases. 4. All cases didn't have any accurate trauma history, but one case was in orthodontic treatment, another case was postextraction site area. 5. Radiologically, "scalloping appearance" were evident in all cases; in 3 cases, multilocular tendency and only one case seen intact mandibular canal image. 6. Histologically, alll section showed bone trabeculae with blastic activity, 2 cases showed no epithelial lining, and other 2 cases were seen innflammatory cell infiltration in edematous tissue. 7. Surgical intervention (curettage) was that treatment of choice.
