Aplasia cutis congenita is a rare disorder characterized by localized or generalized absence of skin at birth. The various hypothesis and classification are proposed. Type V in Frieden's classification, which is associated with fetus papyraceus or placental infarcts, occurs as a large cutaneous defect on the trunk and extremities. We experienced the patient had skin defect affecting the lower abdomen symmetrically, with no family history of the any disorders or chromosomal anomalies and associated anomalies. A twin fetus was died in utero. We report a case of aplasia cutis congenita associated with fetus papyraceus with the review of the associated literatures.

STATEMENT OF PROBLEM: Proper finishing and polishing enhance both the esthetics and the longevity of restored teeth. Blade finishing technique would be suited for smoothing and finishing. Evaluation of this technique are necessary. PURPOSE: The purpose of this study was to evaluate the blade finishing and polishing procedures on the surface profile and roughness of ormocer-based composite resin and nanohybrid composite resin. MATERIAL AND METHODS: The material included a ormocer-based composite resin (Admira(R) & Admira(R) Flow); a nanohybrid composite resin (Grandio(R) & Grandio(R) Flow). One hundred forty specimens of each group were prepared using a mylar strip and randomly divied into blade finishing and rubber polishing groups (n=10). The average surface roughness (Ra) in micrometers was measured and the surface profile was examined by scanning electron microscopy (SEM) (Magnification X 200). The data were analyzed by Mann-Whitney Test at 0.05 significance level. CONCLUSION: The results of this study indicated that the mylar strip produced the smoothest surface on all materials and among the finishing-polishing methods was not significanct difference (P>0.05). Ormocer-based flowable composite resin performedthe lowest variability in initial surface roughness among the tested materials.

STATEMENT OF PROBLEM: Over the past decade, increased demand for esthetically pleasing restorations has led to the development of all-ceramic systems. Recent reports suggest that the all-ceramic crowns have excellent physical properties, wear resistance, and color stability. In addition, numerous ceramics have excellent biocompatibility, a natural appearance, and improved physical bonding with resin composite luting agents. However, the brittle nature of ceramics has been a major factor in their restriction for universal usage. Functional occlusal loading can generate stress in the luting agent, and the stress distribution may be affected by the marginal geometry at the finish line. Tooth preparation for fixed prosthodontics requires a decision regarding the marginal configuration. The design dictates the shape and bulk of the all ceramic crowns and influences the fit at the margin. PURPOSE: The purpose of this study was to evaluate the stress distribution within marginal configurations of all- ceramic crowns (90-degree shoulder, 110-degree shoulder, 135-degree shoulder). MATERIAL AND METHODS: The force is applied from a direction of 45 degrees to the vertical tooth axis. Three-dimensional finite element analysis was selected to determine stress levels and distributions. RESULTS AND CONCLUSION: The result of stress level for the shoulder marginal configuration was more effective on stress distribution at 135-degree shoulder margin. But the stresses concentrated around at 135-degree shoulder margin. The stress decreased apically at the surface between cements and alumina core, and increased apically at the surface between alumina core and veneering porcelain.

A Foreign body in the gastrointestinal tract is a common clinical problem seen in all age groups and rarely produces symptoms. However, the foreign bodies should be removed if they produce symptoms or remain in the gastrointestinal tract. A 31-year-old man with schizophrenia ingested a 20-cm-sized toothbrush. It passed through the ileocecal valve and penetrated the hepatic flexure of the colon and liver. It was removed successfully by using a surgical procedure. We report this unusual case of colonic perforation by an ingested toothbrush and review the related literature.

PURPOSE: The purpose of this study is to determine factors affecting happiness of adolescents who attended community child centers. METHODS: We surveyed 154 adolescents attending a community child center in P City with a structured self-report questionnaire from October 3 to October 15, 2016. Data was analyzed by SPSS 18.0 descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients and stepwise multiple regression. RESULTS: The mean scores of family strength, friend support, teacher support, and happiness were 3.8±0.84, 3.8±0.98, 3.7±0.84 and 3.7±0.63. There were significant differences in happiness according to the subjects' number of close friends and duration of their stay at the community child center. There were a significant positive correlations among family strength, friend support, teacher support, and happiness. The most significant factors affecting happiness included friend support (β=.40) and peaceable family strength (β=.35). These variables explained 44% of the total variance in happiness. CONCLUSION: It is desirable to prepare and support measures to increase friends' support and family strength in order to improve happiness of adolescents attending community child centers. The findings suggest that it is necessary to develop nursing intervention programs to promote friend support and family strength.

PURPOSE: It has been suggested that an ulceration or hemorrhage within an atheroma on a stenotic carotid artery is a clinically important cause of transient ischemic attack(TIA). In previous studies, due to its inherent signal loss by static or turbulent flow, magnetic resonance angiography(MRA) proved to be an unreliable methed for the evaluation of subtle changes of ulceration. To improve the detectability of the ulceration within atheroma, avascular phantom was filled with gadolinium solution of various concentrations during various MR sequences. MATERIALS AND METHODS: Several vascular phantoms made of elastic silicon mimicking an ulcerated stenotic internal carotid artery(ICA) were constructed, and gadolinium solution of different concentrations (1:1000 and 1:200 of Gd-DTPA) and distilled water were introduced into the vascular phantoms using a computerized pulsatile pump. To evaluate maximum intensity projection(MIP), multiple planar reconstruction(MPR) and source images, axial and coronal images of MRA with 2D-TOF(time of flight) and 3D-TOF were reviewed. Each image of various sequences was compared with plain X-ray films of each phantom filled with barium. RESULTS: On all MR suquences, the images of the phantom of the normal carotid bifurcation were superior to the images of ulcerated and stenotic phantoms. MPR and MIP were the optimal image for detecting and defining ulceration and stenosis. Better quality images were obtained when a higher concentration of Gd-DTPA was used and when the 3D-TOF technique instead of the 2D-TOF technique was applied. CONCLUSION: This study reveals that a combination of higher concentration gadolinium with MPR and MIP on 3D-TOF technique could be optimal for the evaluation of ulceration and/or stenosis at the bifurcation of the carotid artery.

The authors studied 16 cases of craniopharyngioma who admitted to the Department of Neurosurgery of Dong San Medical center, Keimyung university, during the past 5 years from 1981 to 1985. Of these 16 cases, 9 belonged to a juvenile group with ages under 20 based on full pubertal development, and 7 cases belonged to an adult group. It was observed the difference between the age groups of the clinical, neuroradiogical and histopathopathological findings. Raised ICP symptoms were showed in juvenile group and decreased vision and visual field defect in adult group, respectivelly, as the chief complaint. All cases of the juvenile group were classified as juvenile type and three cases out of seven in the adult group were adult types in their histopathological pattern. Four juvenile types of adult group showed poor outcome. We concluded that subtotal resection with radiotherapy gave a better prognosis in both group and that hormone therapy before and operation decreased mortality and morbidity and improved the quality of survival significantly.
