Atrial myxomas are uncommon, but surgical treatment offers a potential cure. Early diagnosis is essential so that tumors can be promptly removed in order to reduce morbidity or mortality from atrioventricular valve dysfunction and embolic complications. They are intracavitary tumors occurring within any of the cardiac chambers, but they have a predilection for the atria, particulary the left atrium. The development of noninvasive, echocardiogaphic technique has made it possible to screen large numbers of patients with atrial myxoma with ease and safty. Recently the development of diagnostic procedure and cardiac surgery increased the accuracy of diagnosis and the opportunity of successful ereatment. We report the two cases of left artial myxomas which were removed successfully by surgery.

OBJECTIVES: To investigate the factors associated with symptoms from job stress among Korean dental laboratory technicians. METHODS: We collected the data of 786 technicians for life-style, job stressor, social support, self-esteem, personality, and various dimension of stress symptoms included roomatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and hostility by self-administerd questionnaire. Global severity index of dental technician (GSID) was calculated by total sum of sub-dimension. RESULTS: We used 80 percentile as a cut-off point, and got the 81.5 % of sensitivity, 86.1 % of specificity by receiver operating characteristic curve. The odds ratios of various factors in high group of GSID compared with low group were 1,49(95 % Cl 1.00-2.00) for smoker, 1,53 (1.06-2.21) for unhealthy group, 6,69 (4.74-9.44) for work overload, 8.34(5.82-11.97) for work demand, 9.89 (6.76-74.94) for work process, 8.27 (5.80-11,79) for work environment, 5.82 (4.04-8.39) for interpersonal relationship, 8.34 (5.82-11.97) for occupational conflict, 5.70 (4.04-8.04) for labor remuneration, 7.58 (5.37-10.71) for role conflict, but 0.39 (0.27-0.57) for social support, 0.41 (0.29-0.60) for self-esteem. By multiple logistic regression, factors were significantly associated with GSID were age, working area, role overload, work demand, work procedure, physical environment, occupational conflict, role conflict, social support, personality traits. CONCLUSIONS: Factors associated with symptoms from stress were role overload, work demand, work procedure, occupational conflict, interpersonal relationship, labor remuneration and role conflict in Korean dental laboratory technicians. It is suggested that health promotion program to reduce job stress and to enforce social support and self-esteem should be developed.

Neurilemmomatosis is a clinical entity consisting of multiple cutaneous neurilemmomas, central nervous system tumors, and neurologic disorders. Since Shishiba et al first described the disorder in 1984, several cases have been reported. We report a Korean case of neurilemmomatosis showing multiple neurilemmomas of the skin and spinal cord, with associated motor and sonsory nerve disturbance. Histologic, immunohistopathologic and electron microscopic studies confirmed the diagnosis.

This study was undertaken to observe the difference of patch test and prick test positive reactions in three groups, 20 atopic dermatitis patients, 20 chronic urticaria patients, and 20 normal controls, Twenty commercial antigens (ToriiCo.) and twenty three frozen and boiled antigens of fishes and shellfishes were used as test materials. The results were as follows: 1. No positive reaction was observed in all sixty subjects in patch test. 2 In prick test, difference in reactivity was observed among atopic dermatitis (14. 7%), chronic urticaria (8.7%), and normal control(1. 5%) 3. There was significant difference in reactivity between Torii and frozen antigens in atopic dermatitis group, but no significance in chronic urticaria and control groups. 4. Boiling altered the reactivity in tested materials in all three groups of subjects singificantly. 5. Patients with past or family history of allergic diseases showed double fold higher reactivity tban patients without any history.
