Malignant struma ovarii is a rare tumor of the ovary. This can be diagnosed by histologically when carcinomas of the thyroid gland are excluded. We present a case of malignant struma ovarii arising from cystic teratoma. A 42-year-old female was admitted for evaluation of lower abdominal mass. Hysterectomy and both adnexectomy were performed on the basis of a clinical impression of uterine leiomyoma and an ovarian mass. The uterus revealed intramural leiomyoma, measuring 8 cm in diameter. Ovarian mass was predominantly cystic and partly solid. Microscopically, thyroid tissue with papillary structures were found in the solid area Papillae were complex, branching and randomly oriented. These papillae were infiltrated in the adjacent fibrous capsule, Clinical evidence of a primary thyroid carcinoma was not found.

Although most authors regard contralateral pedicular fracture with unilateral spondylolysis as an unstable condition and recommend surgical management when immobilization fails in promoting bony healing of the fracture, few researchers have investigated the natural history of pedicle fracture or the causal relationship between symptoms and the fracture. In addition, there are no detailed guidelines that address the management of this disease. We report a rare case of contralateral pedicular fracture associated with unilateral spondylolysis at the L5 level which was successfully treated by rehabilitation with activity modification.

The effect of topical application on the number of S. mutans was tested in a group of 44 orthodontic patients (mean age, 12Y 3M). They were divided into 5 groups according to the method using NaF and SnF2. The number of S. mutans CFU were counted in stimulated saliva of each subject at baseline, and after one, two, three, and eight weeks. The following results were obtained. 1. In NaF rinsing group, and NaF topical application and NaF rinsing group, the number of S. mutans per ml saliva was not significantly changed. 2. In SnF2 topical application group, and SnF2 topical and NaF rinsing group, the number of S. mutans per ml saliva was significantly reduced. 3. After 8 weeks, there were no significant reduction of the number of S. mutans in comparison with baseline.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea. The subjects were 64 Chinese college students in Korea (educated group, 32 students vs. non-educated group, 32 students). Educated group was lessoned as group and/or individual. Nutrition education program consisted of four lessons (40min / lesson), '6 major nutrients & function (group lesson)', '6 food group and sources (group lesson)', 'personalized daily needed energy and food exchange units using Food Exchange System (individual lesson)', and 'smart choice of snacks and eating-out foods (group lesson)'. We examined the differences between educated group and non-educated group in nutrition knowledge, dietary attitudes and nutrients intake. After education, there were positive improvements on nutrition knowledge: 'function and foods of 6 nutrients', on dietary attitudes: 'type of breakfast' in educated group. In the evaluation of nutrient intakes according to Dietary Reference Intakes for Korean (KDRI), there were positive improvements on intake levels of riboflavin, fiber, vitamin B6, vitamin C, folate, Ca and K in the educated group. In the index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased in the educated group. In conclusion, it is possible to improve nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea through the nutrition education focused on personalized daily needed energy and food exchange units.

OBJECTIVES : Long acting injectable antipsychotic medication have the ability to sustain the drug effect for a long duration, thus enabling advances in the management of those psychiatric patients who have poor compliance or who have difficulty getting the oral form of their antipsychotic medications. Despite their benefits, previous studies have reported that depot antipsychotics have a much lower prescription ratein the treatment of schizophrenia or schizoaffective disorder. Psychiatrist's attitude toward depot antipsychotics clearly has an influence on the decision-making process regarding the selection of medications. Until now, there has been no data with respect to psychiatrists' attitudes regarding long-acting injectable antipsychotics in Korea. This study examined these attitudes toward antipsychotic depot medications as well as the factors which could contribute to their choice of depots. METHODS : We questioned 347 psychiatrists, who had been attending a conference, about their attitudes toward depot antipsychotic treatment. RESULTS : The most important factor causing reluctance with respect to prescribing depot treatment (for both classes of antipsychotics) was a presumed sufficient level of compliance with available oral antipsychotic treatments. In addition, typical depots are not considered to be an appropriate treatment option for first-episode patients, and as a result, they are used sparingly. Lastly, atypical longacting injectable drugs are avoided due to their strict criteria of insurance and high treatment costs. CONCLUSION : Aversions to prescribe depot treatment are frequent among psychiatrists and appear to be unrelated to the antipsychotic class. The stated reasons for not choosing depots are generally not supported by the current literature. Further research is required to clarify the advantages using depot treatments.

Endoscopic ultrasonography (EUS)-a combination of endoscopy a.nd ultrasonography was one of the most useful tools for diagnosis of digestive system diseases. This technique was known to be very effective in the assessment of depth of invasion in gastric cancer and in pancreatico-biliary diseases. We performed EUS in 589 patients with upper gastrointestinal and pancreatico-biliary tract lesion prior to surgery for past 22 months and examined the diagnostic accuracy of EUS, respectively. The results were compared to surgical histology in esophagus and stomach cancer,to concordance witb endoscopic retrograde cholangiopancreatography(ERCP) results for pancreaticobiliary diseases. 1) In 589 patients diagnosed with EUS, the mean age of the patients was 55.9 years with a male to female ratio of 1.7: 1. 2) Patients were divided into three groups; post-upper gastrointestinal endoscopy, post ERCP and undiagnosed with other diagnostic tools. 3) Among post-upper gastrointestinal endoscopy, 64 cases were operated due to esophageal and gastric cancer and then compared to surgical histology. After compared, EUS accuracy on depth of invasion was 78.1% and sensitivity and specificity on lymph node metastasis in gastric cancer were 76.9% and 74.3%, respectively. 4) In post-ERCP cases, EUS results were compared to ERCP results and then concordance rate was 95.4%. 5) In undiagnosed cases, EUS was performed and results were reported.

Endoscopic Variceal Ligation(EVL) was developed as an alternative to endoscopic injection sclerotherapy(EIS) for decreasing of complication rate. This new technique involves placement of small elastic O-rings around the variceal channels in the distal esophagus. To evaluate the efficacy of EVL for treatment of the acute bleeding esophagea1 varices and the efficacy of prophylactic EVL, we compared EVL in 88 patients who had recently bled from esophageal varices(Group 1) and prophylactic EVL in 45 patients with large size(Grade 2 or 3 or 4) and red color sign on endoscopic finding who had not previously had upper gastrointestinal bleeding(Group 2). Also, we compared prophylactic EVL group(Group 2) and control group(Group 3) who did not performed EVL. At the time of treatment 28.4%(25/88) of patients had active bleeding. They were all treated acutely with EVL and repeated treatment for the long-term goal of variceal eradication. Initial hemostatic efficacy of EVL for acute bleeding varices was 92%(23/25). Varices were eradicated or reduced to Grade 1 in 68%(17/2S). Early mortality rate within 2 weeks was 8%(2/25). Among patients who had eradicated or reduced to Grade 1 varices by repeated EVL sessions, over a mean follow-up of 11 months there was no difference between Group 1 and Group 2 in recurrent rate(49.1%(27/63) vs. 46.8% (15/32)), rebleeding rate(10.9'Yo (6/55) vs. 9.3% (3/32)), rebleeding interval(average 75 days vs, 83.6 days). There was significant difference between prophylactic EVL group and con- trol group in bleeding rate(9.3%(3/~32) vs. 43.7%(14/32))~(p<0.05). Three patients(6.6%) died in prophylactic EVL group, two from ligation site bleeding of esophageal varix, one from hepatic failure. In conclsion, EVL is an effective method for treatment of acute bleeding esophageal varices with repeated sessions. Although prophylactic EVL can be used to prevent bleeding by eradication with lower initial morbidity are necessary because of EVL-related complications.

BACKGROUND: A receptor tyrosine kinase for ephrin ligands, EPHB2, is expressed in normal colorectal tissues and colorectal cancers (CRCs). The aim of this study was to investigate EPHB2 expression over CRC progression and determine its prognostic significance in CRC. METHODS: To measure EPHB2 mRNA and protein expression, real-time polymerase chain reaction and immunohistochemistry were performed in 32 fresh-frozen and 567 formalin-fixed paraffin-embedded CRC samples, respectively. We further investigated clinicopathological features and overall and recurrence-free survival according to EPHB2 protein expression. RESULTS: The EPHB2 level was upregulated in CRC samples compared to non-cancerous tissue in most samples and showed a strong positive correlation with AXIN2. Notably, CD44 had a positive association with both mRNA and protein levels of EPHB2. Immunohistochemical analysis revealed no difference in EPHB2 expression between adenoma and carcinoma areas. Although EPHB2 expression was slightly lower in invasive fronts compared to surface area (p < .05), there was no difference between superficial and metastatic areas. EPHB2 positivity was associated with lymphatic (p < .001) and venous (p = .001) invasion, TNM stage (p < .001), and microsatellite instability (p = .036). Kaplan–Meier analysis demonstrated that CRC patients with EPHB2 positivity showed better clinical outcomes in both overall (p = .049) and recurrence-free survival (p = .015). However, multivariate analysis failed to show that EPHB2 is an independent prognostic marker in CRCs (hazard ratio, 0.692; p = .692). CONCLUSIONS: Our results suggest that EPHB2 is overexpressed in a subset of CRCs and is a significant prognostic marker.
