We herein described a 27 year-old male who has been suffering from pruritic erythematous wheal and flare on sun-exposed areas, especially the midback for the past, ten months. The action spectrum of this patient was between 320 and 400 nm, .Passive and reverse passive transfer tests were negative. According to the classification by Harber et al, the current case seemed to belong to type II.

All-ceramic restorations have become an attractive alternative to porcelain-fused-to-metal crowns. In-Ceram, and more recently IPS Empress 2 were introduced as a new all-ceramic system for single crowns and 3-unit fixed partial dentures. But their strength and marginal fit are still an important issue. This study evaluated the fracture resistance and marginal fit of three systems of 3 unit all-ceramic bridge fabricated on prepared maxillary anterior resin teeth in vitro. The 3 all-ceramic bridge systems were: (1) a glass-infiltrated, sintered alumina system (In-Ceram) fabricated conventionally, (2) the same system with copy-milled alumina cores (copy-milled In-Ceram), (3) a heat pressed, lithium disilicate reinforced glass-ceramic system (IPS Empress 2). Ten bridges of each system with standardized design of framework were fabricated. All specimens of each system were compressed at 55degree at the palatal surface of pontic until catastrophic fracture occurred. Another seven bridges of each system were fabricated with standard method. All of the bridge-die complexes were embedded in epoxy resin and sectioned buccolingually and mesiodistally. The absolute marginal discrepancy was measured with stereomicroscope at x50 power. The following results were obtained: 1. There was no significant difference in the fracture strength among the 3 systems studied. 2. The Weibull modulus of copy-milled In-Ceram was higher than that of In-Ceram and IPS Empress 2 bridges. 3. Copy-milled In-Ceram (112micrometer) exhibited significantly greater marginal discrepancy than In-Ceram (97micrometer), and IPS Empress 2 (94micrometer at P=0.05. 4. The lingual surfaces of the ceramic crowns showed smaller marginal discrepancies than mesial and distal points. There was no significant difference between teeth (incisor, canine) at P=0.05. 5. All-ceramic bridges of three systems appeared to exhibit sufficient initial strength and acceptable marginal fit values to allow clinical application.

PURPOSE: The purpose of this study was to identify an influence of self-esteem and family- support on powerlessness of hospitalized elderly patients with chronic disease. METHOD: The subjects were 151 hospitalized elderly patients, age over 60, with chronic disease and admitted for at least 1 week. The data were collected by individual interview using a tructured questionnaire during the period from July 10th to August l0th, 2003 from three general hospitals in Busan. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation, hierarchical multiple regression. RESULT: The level of self-esteem, family support, and powerlessness was 38.00, 38.26, and 38.38, respectively. There was a significant positive correlation between self-esteem and family support and a negative correlation between self-esteem and powerlessness and between family support and powerlessness. Self-esteem and family support were each significant predictor of powerlessness. CONCLUSION: This study showed the hospitalized elderly patients need greater family-support and higher self-esteem to relieve the level of powerlessness. I suggest to study for replication in a larger sample size and considering the lengths of hospitalization for generalization of this study and to develop individual intervention programs for increasing family support and self esteem and testify their effects on the relief of powerlessness of the elderly.

Purpura fulminans is one of rare consumptive coagulopathy in children. The most common predisposing conditions of purpura fulminans are infectious disease like streptococcal infection and chickenpox. This disease is characterized by ecchymotic lesions that are usually distributed symmetrically on the lower extremities and buttocks. These ecchymotic lesions undergo necrosis, unless there is effective treatment. We experienced 3 cases of purpura fulminans which improved almost completely after early heparin administration. In the case 1, a 12 month old girl, purpura fulminans developed during sepsis and gastroenteritis. In the case 2, a 4 month old boy, purpura fulminans developed during acute sepsis. We reported 3 cases with a brief review of related literature.
