Mucoepidermoid earcinoma occurred in about 2% among salivary gland tumor and in about 15% among malignant parotid gland tumor. The tumor occurred usually in elderly persons and arose as innocent-appearing swelling in the parotid gland region with gradual painless enlargement without alarming and it's usual size is less than 2 cm, However, a few of the poorly differentiated neoplasms grew rapidly and were painful and accompanied by facial nerve paralysis in about 15%. But it's prognosis is better than other salivary gland origin. We report a case of typical mucoepidermoid carcinoma of parotid gland origin which is occurred in 15 years old girl. The tumor begins pea sized painless nodule since about 2 years ago, and enlarged gradually to apple size and accompanied by facial nerve paralysis and pain sensation recently. But there was no evidence of tumor in parotid gland itself and no metastasis.

It is known that the activated peripheral T lymphocytes are increased in patients with autoimmune disorders such as systemic lupus erythematosis, rheumatoid arthritis, multiple sclerosis and autoimmune thyroiditis, but not in the patients with myasthenia gravis on previous studies. We investigated the subsets of T cells in peripheral blood of the patients with myasthenia gravis using flow cytometric analysis. Forty-three patients of myasthenia gravis who were not on steroid or other immunosuppressants were chosen, and thirty-six age-matched healthy persons were evaluated as controls. The peripheral blood mononuclear cells from patients and controls were stained with FITC or PE-conjugated monoclonal antibodies to several surface molecules expressed on T cells within 6 hours after collection. The samples were analysed by flow cytometry within 24 hours. In patients with myasthenia gravis, the expressions of DR and CD25 molecules on the T lymphocytes were increased significantly compared to those of the control group. The expression of CD25 was increased on CD4+ T cells, but not on CD8+ T cells . The expression of DR molecule was increased on CD8+ T cells, but not on CD4+ T cells. Therefore we suggest that the activated T cells are increased in myasthenia gravis and CD25 surface markers on CD4+ T cells may be a more sensitive indicator of immune status.

Despite major diagnostic advances, 10-30% of hepatic metastases of colorectal carcinoma remain undetected. In this study, CEA levels of peripheral (p-CEA), drainage venous blood(d-CEA) and gallbladder bile(b-CEA) in patients with colorectal cancer were determined to examine the significance of their CEA levels in predicting hepatic metastases. From January 1993 through May 1996, p-CEA, d-CEA and b-CEA were obtained in 50 colorectal carcinoma patients without gallbladder pathology. Synchronous hepatic metastases were found in 5 patients(Hm group) and 45 cases had no hepatic metastasis. Among the 27 cases who followed up over 2 years, metachronous hepatic metastases(Hr group) were found in 6 cases and remaining 21 cases had no metastases(Ho group). Elevation of p-CEA, d-CEA, and b-CEA was significantly correlated with lymph node metastases and hepatic metastasis. The b-CEA levels were significantly correlated with p-CEA(r=0.533926, p<0.0001) while d-CEA levels were not(r=0.276437, p=0.0520). Although all the levels of p-CEA, d-CEA, and b-CEA in Hr & Hm group were significantly higher than those in Ho group, d-CEA level was considered as most sensitive index in predicting hepatic metastases(mean 12.7 ng/ml in Ho, 88.6 in Hr, and 137.3 in Hm group. p<0.0001). The possible cut-off level of d-CEA was 40 ng/ml because all of the cases with d-CEA < 40 ng/ml had no hepatic metastasis nor hepatic recurrance, whereas 11 out of 12 patients with d-CEA > 40 ng/ml had hepatic metastases(5 synchronous, 6 metachronous). However it is impossible to establish the possible of b-CEA because of high false positive and negative rate in predicting metachronous hepatic metastases. In conclusion, it is suggested that d-CEA could be highly sensitive indicator for selecting high-risk patients of metachronous hepatic metastases of colorectal cancer.

PURPOSE: The purpose of this study was to assess the satety and effectiveness of lacrimal trephination and balloon dilatation in treatment of obstruction of the lacrimal canaliculus. METHODS: Lacrimal trephination and subsequent balloon dilation was performed in 7 eyes of 7 consecutive patients with epiphora due to lacrimal canalicular obstruction and common canalicular obstruction. RESULTS: The average age of patients was 50.3 years old and the average follow-up period was 17.7 months. Anatomical success was 7 of 7 eyes (100%) and functional success , resolution of epiphora was 5 of 7 eyes (71%) CONCLUSIONS: Lacrimal trephination and subsequent ballooning canaliculoplasty in treatment of obstruction of the lacrimal canaliculus seems to be safe and valuable as an primary procedure before Jones tube bypass surgery.

As the productive activities have vastly increased following industrialization and urbanization in the modem society, the resulting high mobility of people and goods have caused a sharp increase in the accidents in the work places as well as traffic accidents. In particular, deaths caused by injuries are generally concentrated in the economically active young peoples, producing incalculable losses to the society and nation as a whole. Advanced nations with superior medical care systems have succeeded in reducing incidents of such deaths by operating trauma centers. Especially noteworthy is the case of the United States where such specialized trauma centers have greatly contributed to reducing deaths from injuries in the non-urban areas with less access to medical facilities. At present Korea has no medical centers specializing in injuries. In large cities, the injuries are being treated tertiary medical facilities while in the provinces they are referred to small and medium-sized hospitals that constitute secondary medical facilities. Currently in Korea the Trauma patients are treated at general hospitals that consist of 726 secondary medical facilities and 40 tertiary medical centers nationwide. The secondary medical facilities which tend to take most responsibility for the treatment of trauma are generally deficient in medical staff and facilities (including operating and intensive care facilities). Despite such deficiency and limitations, no regulations exist regarding treatment or transportation of trauma patients. This article reports the outcome of a comparative analysis of the results of trauma treatments among different types of medical facilities based on objective data in the hope that such study would facilitate a comparison with the treatment systems of advanced countries and thereby contribute to a precise formulation of problems that must be addressed in this area.
