Accurate reproduction of intraoral tissue is essential in the fabrication of fixed prosthesis. This selection of impression material and method is very important. In this study, vinyl polysiloxane type impression material Panasil was used. Three impression methods ; one-step technique, individual tray technique, and individual tooth tray technique using the vinyl polysiloxane type bite registration material Futar Occlusion, were used to take horizontal and vertical impression. Improved stone models were fabricated. The amount of occlusal surface discrepaneies, interabutment distance discrepancies, amount of marginal defect were evaluated with the X-PLAN360d and photoscanning. The results were as follows. 1. There was no significant difference in occlusal surface according to the directions and techniques of impression taking. 2. There was no significant difference in interabutment distance discrepancies according to the directions and techniques of impression taking 3. There was no significant difference in marginal discrepancies according to the direction of impression taking but there was significant difference between one-step technique and individual tray technique, individual tooth tray technique (P<0.05). Taken together, these results suggest that individual tray technique and individual tooth tray technique are more accurate for impression taking than one-step technique.

Dental porcelain should have adequate strength and similar esthetics as natural teeth. Recently esthetics has become a high priority in clinical dentistry. Thus the evaluation of color stability of dental porcelain has become an important part in dental research. The purpose of this study was to evaluate the difference in color stability of 3 types of porcelain (Vintage, VMK 95, CERAMCO II). The porcelain were divided into groups by 2 types of treatment (Glazing or non-glazing and thermocycling or non-thermocycling). The porcelain wee dyed with methylene blue and distilled water, and then the color stability was evaluated with a spectrophotometer. The results were as follow ; 1. The color change of porcelain increased in the order of VMK 95, Vintage, CERAMCO II. But there was no significant difference. 2. The color change decreased in the glazing group compared to the non-glazing group(p<0.05). 3. The color change increased after thermocycling But there was no significant difference. 4. The color change according to dye method was significantly larger with methylene blue copared to distilled water(P<0.05).

PURPOSE: The aim of this study was to determine the genotype frequencies of interleukin 10 (IL-10) gene polymorphisms and to investigate their association with the risk of respiratory distress syndrome (RDS) in preterm Korean infants. METHODS: Two hundred fourteen preterm infants born at Ewha Womans University Mok Dong Hospital between November 2003 and July 2008 were studied. The cord blood of preterm neonates and the corresponding maternal blood were analyzed by PCR for IL-10 gene (IL-10 -1082A/G, -819T/C, and -592A/C) polymorphisms. The clinical data of patients were collected retrospectively by chart review. RESULTS: The genotype frequencies of IL-10 genes in Korean mothers with preterm infants differ from other reports. The prevalence of two promoter SNPs of the IL-10 cytokine gene was similar but none had the IL-10-1082GG homozygote. Multiple logistic regression analysis demonstrated the risk of RDS to be significantly lower in the infants of the mothers with an IL-10-592AC/CC genotype than in those with an AA genotype (P= 0.033). The risk of RDS was significantly lower in the mother with an IL-10-819TC/CC genotype than in those with a TT genotype (P=0.030). However, IL-10 polymorphisms in the cord blood were not significantly different in preterm infants with RDS compared with the preterm infants without RDS. When we compared the incidence of RDS and each IL-10 A-1082G/T-819C/A-592C haplotype, the ACC haplotype had a protective effect on RDS (P=0.007). CONCLUSION: We conclude that the maternal IL-10-592A/C and IL-10-819T/C polymorphisms may have a role in the development of the RDS in preterm infants.

The spindle and epithelioid cell nevus, is known also as Spitz's nevus or benign juvenile melanoma. The histologic picture of the lesion often closely resembles that of a malignant melanoma, but spindle and epithelioid cell nevus hehaves benignly. Criteria for accurate histological diagnosis of this nevus now exist. However, a difficult lesion occasionally brings one to the worrisome situation even now. We experienced four cases (three children and one adult) of spindle and epithelioid cell neveus with nodular or macular skin lesions. In children (7/F, 9/F, 4/M), all of the lesion show a solitary pinkish red or light brown nodular firm masses, 0.7 cm to 1.0 cm in greatest dimension, which are located at the left posterior thigh, posterior neck and right anterior neck region, respectively. In adult (36/F), the lesion shows a light brown, erythematous macule, 0.8 cm in greatest diameter, in the skin of the back. Microscopically, both spindle and epithelioid cells are found in all the four cases, but epithelioid cells predominate in children and spindle cells predominate in adult.

BACKGROUND: The purpose of this study was to evaluate the usefulness and safety of the anterosuperior deltoid splitting approach for fixation of displaced proximal humeral fractures by analyzing the surgical outcomes. METHODS: Twenty-three patients who could be followed-up for at least 8 months after the treatment of displaced proximal humeral fractures through the anterosuperior deltoid splitting approach were enrolled. We evaluated the reduction of the fractures and surgery-related complications at the last follow-up using X-ray results and clinical outcomes comprising the University of California at Los Angeles (UCLA) scoring system and the Korean Shoulder Society (KSS) score. RESULTS: At the last follow-up of patients treated using the anterosuperior deltoid splitting approach for internal fixation of proximal humeral fractures, we found 22 cases (95.6%) of bone union, a mean UCLA score of 28.3 (range, 15 to 34) and a mean KSS score of 82.1 (range, 67 to 95). Various surgery-related complications were noted; a case of varus malunion after fracture displacement, a case of nonunion, a case of delayed union, two cases of impingement, and a case of partial axillary nerve injury, which recovered completely through the follow-up. CONCLUSIONS: Plate fixation using the anterosuperior deltoid splitting approach could be another reliable option for treating displaced proximal humeral fractures.

PURPOSE: Cancer is the most frequent cause of death in Korea. Cancer screening can save lives through early detection. This study was to investigate major cancer screening rates and the reasons for not having been screening. METHOD: 210 participants of registered nurses from 5 general hospitals in Busan, Korea were completed a structured self-administered questionnaire. Data were analyzed using descriptive statistics with SPSS WIN 10.0. Results: The cancer screening rates of the subjects were 53.8% in Pap smear test for cervical cancer, 41.0% in gastroendoscopy for stomach cancer, 15.7% in mammograpy for breast cancer, and 3.8% in colonoscopy. And the higher proportions of having regular screening were 9,5% in Pap smear test and 2.9% in gastroendoscopy. The primary reason related to not having a screening test was 'seems to be healthy'. CONCLUSION: The findings showed the necessity of recognizing and educating Korean nurses to have a regular cancer screening for their health management.

PURPOSE: To evaluate the signal characteristics of intracranial hemorrhage, as seen on fluid attenuatedinversion recovery(FLAIR) MR imaging according to various stages, and to compare FLAIR imaging with spin-echo T1-and T2-weighted MR imaging. MATERIALS AND METHODS: We retrospectively evaluated fast FLAIR images along withspin-echo T1- and T2-weighted MR images of 32 lesions in 26 patients (12 males and 14 females, aged 3-84 yrs) withintracranial hemorrhagic lesions. For imaging, a 1.5T unit was used, and the nature of the lesions was found to beas follows : intracranial hemorrhage(n=15) ; tumor(n=9) ; infarction (n=4) ; arteriovenous malformation (n=3) ;and arachnoid cyst with hemorrhage(n=1). On the basis of spin-echo MR imaging, lesions were classified as acute,early subacute, late subacute, early chronic, or late chronic stage. The signal characteristics of intracranialhemorrhage were analysed in accordance with each staging, as seen on MR FLAIR imaging, and compared to the stagingseen on spin-echo T1- and T2-weighted MR imaging. RESULTS: For the 32 hemorrhagic lesions, staging was found to beas follows : acute(n=4) ; early subacute(n=8) ; late subacute(n=11) ; early chronic(n=5) and late chronic(n=1). Inthe remaining three patients with arteriovenous malformation, the stage of the hemorrhage was found to be mixedsubacute and chronic. The signal intensity of hemorrhage, as seen on FLAIR imaging during the acute andearly-subacute stage, was low, and during the late subacute stage it was high ; for T2WI, the findings weresimilar. FLAIR imaging, however, showed that hemorrhage intensity during the early chronic stage was low, and thatof the late chronic stage was very low ; these findings were similar to those of T1WI. CONCLUSION: The signalintensity of intracranial hemorrhage, as seen on FLAIR imaging, was not characteristic ; it was similar to that ofT2WI during the acute and subacute stages, and similar to that of T1WI during the chronic stage. When usedtogether with spin-echo T1- and T2-weighted MR imaging, however, FLAIR imaging may be useful for theclassification of chronic intracranial hemorrhage as either early or late stage.
