This study was performed to evaluate the tensile bond strength and modulus of elasticity of three permanent soft denture liners (Molloplast B , Ufi Gel C , Tokuyama ) before and after thermocycling. And their water sorption were also evaluated. Each soft denture liner was bonded to PMMA denture base resin blocks and the tensile bond strength and modulus of elasticity were measured by using universal testing machine. For the water sorption, weight measured after immersion of soft denture liners in 37+/-1degrees C water bath for 4 weeks. The results were as follows : 1. Molloplast B had the highest tensile bond strength, while Tokuyama had the lowest tensile bond strength, There was no significant difference between Tokuyama and Molloplast B in the both nonthermocycling and thermocycling. There was significant difference in tensile strength of Tokuyama before and after thermocycling(p<0.05). 2. For the modulus of elasticity, there was no significant difference between Ufi Gel C and Tokuyama in the both nonthermocycling and thermocycling. There was significant difference in modulus of elasticity of Tokuyama before and after thermocycling(p<0.05). 3. The failure modes of Molloplast B and Ufi Gel C were nainley adhesive type and that of Tokuyama was mainly mixed type in case of nonthermocycling and cohesive type after thermocycling. 4. The water sorption of each soft liners was within+/-2% in times (p<0.05) but, there was no significant difference among the soft liners in times.

In cholangiographic techniques, the close relationship between choledochal cyst and anomalous union of pancreaticobiliary duct has attracted medical attention. There have been rare cases in which the papilla of Vater was found in a position other than its normal position, and such cases have been reported sporadically. However, such cases are interesting in the anatomical context. In this review, we present our experience of choledochal cyst in a 30-month-old boy in whom the papilla of Vater was positioned in the third portion of the duodenum.

PURPOSE: The purpose of this study was to identify the level of distress and quality of life (QoL) in esophageal cancer patients, and to identify the factors influencing QoL METHODS: A sample of 103 patients who have esophageal cancer were included in a descriptive study. The instruments used were the Distress Thermometer and Problem List, and the Functional Assessment of Cancer Therapy-General (FACT-G) version 4. RESULTS: The mean distress score of the subjects was 4.06±2.04 out of 10. The total mean score of quality of life was 66.39±12.86 out of 108, the highest category was physical well-being with a mean item score of 21.78±5.51, the lowest was emotional well-being with a mean item score of 14.69±3.68. The levels of distress and QoL were negatively correlated (r=−.61, p<.001). Stepwise regression analysis revealed that the QoL of the patients was explained by type of treatment and distress. These variables explained 35% of the variance in QoL. CONCLUSION: The QoL of patients with esophageal cancer was relatively low, and the type of treatment and distress was the most important factor affecting quality of life. Thus, to improve the QoL of patients with esophageal cancer, it is important to assess their distress and to provide appropriate interventions.

Idiopathic small bowel ulceration occurring beyond the duodenum is rare, and less than 5% of all the reported cases have occurred in children. In most of the cases, single ulcer of unknown cause is observed in jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for the complications, such as perforation, hemorrhage or obstruction. We experienced a case of perforation of idiopathic ileal ulceration due to blunt abdominal trauma in a 11-year-old boy. The ileal segment including the lesion was resected and the pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects are discussed, and the literatures were reviewed.

Unstable microsatellite repeat sequences or DNA replication errors(RER) due to defective mismatch repair genes have been reported in a subset of sporadic colorectal tumors and in most tumors of patients of hereditary nonpolyposis colorectal carcinoma(HNPCC). To elucidate the clinicopathological correlation of these RER-positive cancers, we examined 16 cases of colorectal carcinoma of different histologic subtypes(6 cases of carcinoma with no gland formation, 5 cases of mucinous carcinoma and 5 cases of gland forming carcinoma). We detected RER in five cases. The patients with RER-positive cancers had a marked preponderance of carcinoma with no gland formations out of 6 carcinomas with no gland formation were RER-positive cancers) and of cancers proximal to splenic flexure(all of the RER-positive cases were proximal colon carcinomas). We conclude that RER-positive cancers have wiique pathologic features that may be useful for the screening and counselling of patients with hereditary colon cancers.

PSTT has been established as a separate entity distinct from choriocarcinoma since 1983, because of its different morphological features, biologic behavior and response to chemotherapy. Most cases of PSTT have indolent clinical courses, but there have been several reports showing malignant behavior resulted in death of the patient. We report a case of PSTT showing vaginal metastatis. In biopsy specimen, it was difficult to make differential diagnosis from squamous cell carcinoma of uterine cervix due to uniform and mononuclear cytologic characteristics. Immunohistochemical stains for hPL and hCG were not typical for either PSTT or choriocarcinoma. We suggest that poorly differentiated PSTT may synthesize the lesser amount of hPL than typical PSTT and it may behave more aggressively.
