Low back pain patients an controls of shipyard workers were surveyed between June 1995 and september 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

This study aimed at assessing the usefulness of paraffin wax sections for demonstration of ER(estrogen receptor) and PR(progesterone receptor), using brief microwave processing rather than proteolytic predigestion. The receptor status of a breast cancer is often into consideration when planning treatment nowadays. As biochemical receptor assays require large amount of fresh tumor tissue and are not always available for all tumors, pathologists are now increasingly asked to provide a service for the assessment of the receptor status in tissue routine sections. Until recently, immunohistochemical demonstration of receptors was used in frozen sections. Therefore, routinely processed paraffin wax sections of 25 cases of breast carcinoma with known ER and PR concentrations, estimated by the standard DCC(dextran-coated charcoal) biochemical assay, were examined using the ABC immunoperoxidase technique. The results were assessed semiquantitably, using a five grade scoring system. Of the 25 cases examined, with DCC cutoff point being <10 fmol,71% and 75% in positivity of each ER, PR receptor is concordant. Statistic analysis demonstrates high relationship between scoring system of IH method and DCC value in ER (R=0.6061, p=0.001) and PR (R=0.5832, p=0.001). The IH method can provide easily assessed reliable positive information about ER, PR status of breast carcinoma using routinely processed paraffin wax sections.

Cellular schwaninoma is a variant of schwannoma, which is characterized by predominance of cellular Antoni A area, presence of mitotic activity, nuclear hyperchromasia, pleomorphism, and absence of Verocay body. These pathologic features often prompted a misdiagnosis of malignancy. However, the clinical outcome has indicated the benignity of the tumor. We have experienced a case of cellular schwannoma arising from right facial nerve with right hemifacial weakness and erosion of mastoid process. Grossly, it was a 3.5 x 3 cm sized and relatively well encapsulated mass with yellowish, friable cut surface. Microscopically, cellular growth with moderate cellular pleomorphism and some mitotic activity (5/40 HPFS, up to 2/HPF) were noted. Immunostaining for S-100 protein showed diffuse strong positive reaction.

Juvenile dermatomyositis is an uncommon autoimmune disease with classic heliotrope discoloration of eyelids, erythematous skin rash of joints and proximal muscle weakness. Quite different from adults, malignancy is rarely accompanied in juvenile dermatomyositis. However vasculitis, muscle atrophy, calcification and gastrointestinal involvement are often observed in juvenile dermatomyositis. A six year old boy was admitted with chief complaints of general weakness and skin rash. Muscle biopsy was performed which was consistent with dermatomyositis. The patient was treated with intravenous immunoglobulin, steroid, methotrexate and physiotherapy. We report a case of juvenile dermatomyositis.

PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

Pulmonary tumors exhibiting neuroendocrine differentiation are classified as typical carcinoid, atypical carcinoid, and small cell lung carcinoma(SCLC). Travis et al. proposed a fourth category of large cell neuroendocrine carcinoma, which is characterized by light microscopic neuroendocrine appearance, cells of large size, polygonal shape, low nuclear cytoplasmic ratio, coarse nuclear chromatin, with prominent nucleoli high mitotic rate and frequent necrosis; and neuroendocrine features by immunohistochemistry or electron microscopy. High grade neuroendocrine carcinoma (LCAC-NE) revealed aggressive clinical course. We report two cases of neuroendocrine tumors of the lung characterized by a trabecular pattern of large pleomorphic cells with frequent mitoses and wide necrosis. The frequent metastatic sites of atypical carcinoid were liver, bone and brain. One of our case is presented, at first, as an ovarian mass, which shows multifocal rosettes and revealed metastasis from lung. Both cases expressed neuroendocrine differentiation by light microscopy and immunohistochemistry. However clinical neuroendocrine symptom were not present.

Kikuchi's disease is a self-limiting lymphadenitis, predomin;intly of young women who present with cervical lymphadenopathy. We present a case of Kikuchis disease in a 18-year-old female, representing multiple tender subcutaneous mass on her neck, left eyelid and posteriarcuricle. Histopathologically, the biopsied mass was a lymph node showing architectural effacement by necrotic focicomposed of nucear karyorrhexis and mononucl ar cell proliferation.
