Acinic cell tumor, a rare tumor of the salivary gland origin, consists of cells similar to the serous cells of the salivary gland. The tumor is almost exclusively paroti4 gland origin, accounting for 2. 7 to 4. 0% of all parotid tumors. The tumor is not,benign but has at least a low-grade malignant potential. We described herein a case of acinic cell tumor which had occurred on an unusual site, right inner epicanthal area of a 9-year-old girl Microscopically, a hematoxylin-eosin stained biopsy specimen showed rnany lobules com of round or polyhedral tumor cells. Each tumor cell had distinct cell membrane, clear cytoplasm, and relative1y eccentric nucleus. The cytoplasm of tumor cell cantaine4 diastase resistant PAS-positive material.

Background:Insulin dependent diabetes mellitus(IDDM) is known to be a disease characterized by a deficiency of insulin caused by destruction of the pancreatic beta-cells. It has been suggested that the clinical and immunological characteristics of IDDM in Korean are different from those of Caucasian. This study was undertaken to investigate the clinical characteristics and the prevalence of autoimmune markers in type I diabetic children and their prediabetic siblings in Korea. METHODS:Insulin autoantibody(IAA), antiglutamic acid decarboxylase(Anti-GAD) antibody, thyroid autoantibodies such as antithyroid antibody(ATA) and antimicrosomal antibody(AMA), and rheumatoid facter(RF) in 54 type I diabetic children have been measured. Diabetic autoimmune antibodies were also measured in 48 siblings. RESULTS: 1)Clinical characteristics of type I diabetic children were that age of onset was 8.6+/-4.4 years, duration of diabetes was 4.1+/-3.3 years. C-peptide at onset of diabetes was fasting 0.7+/-0.5ng/ml, and postprandial 1.2+/-0.5ng/ml, and HbA1c was 12.5+/-4.3%. 2)The positivity of IAA and anti-GAD antibody of type I diabetic children was 74% and 50% respectively. ATA and AMA positivity of type I diabetic children was 3.7% and 5.6%. however RF was not detected at all. Among the diabetic siblings, 48 persons for anti-GAD antibody, 21 for IAA, 27 for ICA were measured but 1 case was positive for IAA. 3)Clinical characteristics of type I diabetic children were not specific different between IAA and anti-GAD antibody positivity. But the mean age of onset of type I diabetic children was younger in case of both positivity of IAA and anti-GAD antibody than both negativity(7.8 vs 11.4 years old, P<0.05). 4)A case in whose brothers are diagnosed as IDDM has shown that autoantibody of elder brother was positive in both IAA and anti-GAD antibody, and younger brother was also strongly positive in IAA. Another case in whose sisters were IDDM, has shown that, while elder sister was positive in IAA, younger sister strongly positive in both IAA and anti-GAD antibody. 5)In a case of identical twin brother, the elder is type I diabetic child and the younger is normal, elder brother's onset of age was 6 years and 8 months old, and titer of anti-GAD antibody was measured as strong positive. Both ICA and anti- GAD antibody were negative in normal younger brother. First phase insulin release in IV GTT and the insulin levels in oral GTT showed reduction from the normal level in normal brother, and repeat check up showed normal ranges but on-going study is needed under observation. CONCLUSION: The prevalence of autoantibody positivity of type I diabetic children of Korea in this study were IAA 74%, and anti-GAD antibody 50%. Cases with both IAA and anti-GAD antibody positive were shown to be earlier onset. Though titers of auto-antibody in IDDM twins, brothers and sisters were strongly positive, auto-antibodies in siblings of IDDM patients were detected only one case with IAA positive(0.47%). We suggest that the pathogenesis of IDDM in Korean is different from foreign countries in terms of prevalence of autoimmune antibodies and more numbers of diabetic siblings should be tested for further study.

PURPOSE: The purpose of this study was to examine the levels of burnout experienced by Korean hospital nurses (N=198), and to identify predictors of their nursing outcomes such as job performance, work satisfaction, and productivity. METHOD: Hierarchical multiple regression was used to identify predictors of each nursing outcomes. Included predictors were nurses' general characteristics, work- related characteristics (role stress and perceived control), and burnout. Results: Korean nurses experienced higher levels of burnout compared to the cutoffs suggested by Maslach and Jackson (1986) and to those in the USA. For each nursing outcome, predictor variables explained 39% of the variance in role performance, 30% of the variance in work satisfaction, and 38% of variance in productivity. Higher personal accomplishment, lower role ambiguity, being staff nurses, and lower emotional exhaustion were related to higher job performance, and higher productivity. Lower role conflict and role ambiguity were also related to higher work satisfaction. CONCLUSION: Based on the findings of this study, managemental interventions for nurses to reduce their burnout experience are needed. Further study in this area is warranted.
