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.

Primary Myelofibrosis*

Holt-Oram Syndrome, well described by Holt and Oram in 1960, is an autosomal dominant disorder consisting of upper extremity and cardiovascular anomalies with variable expression. A typical case of this syndrome was experienced by authors recently and is to be presented with review of literatures.

The malignant fibrous histiocytoma (MFH) was first introduced in 1963 to refer to a group of soft-issue tumors characterized by a storiform or cartwheel-ike growth pattern and predominantly fibroblastic appearance. It was postulated that they were derived from histiocytes that could assume the appearance and function of fibroblasts. MFH has been recognized to be the most common sarcoma in the soft tissue of late adult life which involves the deep fascia or skeletal muscles of the extremities or retroperitoneum. It has been noted in other organs, however, it rarely arises in the liver. We report two cases of primary malignant fibrous histiocytoma of the liver histopathologically confirmed after surgical resection-storiform pleomorphic and myxoid subtypes in the 55 year old male and 49 year old female patients, respectively, and describes the clinical courses, characteristics and pathologic aspects with review of the related literatures.

Transglutaminase(TGase) is a calcium dependent enzyme that catalyse and acyl transfer reaction forming epsilon-(gamma-glutamyl)-lysine cross linkage. the major known effect of TGase is its important role in the programmed cell death manifested in the granular layer of the skin and acidophilic bodies in the viral hepatitis and neoplastic processes. The enzyme activity, immunohistochemical reaction using polyclonal antibodies against cytosolic TGase C, light and electron microscopic studies and TdT staining of the transplanted fibrosarcoma cells in C3H mouse with radiation therapy were done. The presence of TGase was detected immunohistochemically by avidin-biotin peroxidase complex (ABC) method Apoptosis were significantly induced after irradiation dependent with time factors and irradiation doses, resulted in marked and confluent tumor cell loss. Highest activity of the cytosolic form of TGase was noted at 24 hours and decrease after then while membrane bounded form of the TGase showed no significant changes. Immunohistochemical staining revealed strong positive reaction in the sarcoma cells in diffuse fasion and around the necrotic foci in the cytoplasm. Terminal dideoxynucleotidyl transferase(TdT) staining revealed increasing numbers of apotptic cells from two hours after irradiation. In the mechanism of decreasing tumor size and cell death in radiation therapy, apoptosis plays an important role and during that process transglutaminse might do some irreversible cross-linking effects of cytoplasmic proteins causing cell death in part.

We report a case of subcutaneous fat necrosis associated with pancreatitis that may be the first case in Korean hterature as for we know. The patient was a 41-year-old man wbo presented erythema nodesum-like erythematous subcufaneous nodules on both lower extremities. Histopathologic findings showed subcutaneoms focal fat necrosis and ghoat-like cells. Granular basophilic material was deposited in and around the necrotic fat cells and stained positively with von Kossa stain. The lesioas subsided gradwdly without any specific treatment, as the underlying pancreatitis was ameliorated.

Regular hemodialysis has been established as a way of treatment for end stage renal failure. In adults, hemodialysis 5 hours each time, three times weekly with one square meter hemodialyzer is now widely accepted as a standard, and there are many reports on long term follow up studies. Quite a large difference are present, however, in our community mainly originated from patient's poor compliance in frequent dialysis with short interdialysis interval. The author analyzed 200 cases of chronic renal failure who have received hemodialysis treatments during the 5 year period from July 1976 to June 1981 at the hemodialysis unit of the hanyang University Hospital and the following results are obtained; 1. Actual one year survival rate was much higher in thrice(87.1%) than one(35.1%) or twice(54.1%) weekly dialysis. 2. Long term(more than 6 months) complications were also more frequent in once(85.7%) or twice(70.2%) weekly treatments than in thrice(22.2%). The predominant complications were congestive heart failure, pericarditis, and infections. 3. Those who recieved three times weekly dialysis had better rehabilitation grades than the patients groups of twice or once weekly treatment. 4. Of peridialysis distressful symptoms, nausea, vomiting dizziness were less frequent in the group three times a week dialysis. In contrast, headache, hypotension, muscle cramps, and weakness were not significantly related with frequency of hemodialysis. 5. Those who voided a large amount of urine output had better survival and less frequent requirement of blood transfusions. 6. Main causes of death were due to patient poor compliance, hyperkalemia and cerebrovascular acidents. 7. Economic problems were the major cause of dialysis interruption.
