A 40 year-old female was admitted to our hospital because of proptosis for 4 years. Detecting a 2 cm-sized retrobulber mass on computerized tomography, we extracted well capsulated reddish brown mass, which confirmed as a cavernous hemangioma by histologic examination. One year postoperatively, her proptosis was gone, visual acuity was normal, and ocular motility was good.

OBJECTIVES: This study examined the selective deficits of executive function in patients with mild traumatic brain injury that in normal range of general intelligence level and aimed to analysis of the correlation between K-WAIS result and executive function. METHODS: 59 subjects were included in this study, who were diagnosed as mild traumatic brain injury(MTBI) and they have visited in neuropsychiatric department of Wonkwang University Hospital during from March, 2005 to September, 2010. For measurement of general intelligence quotient, the Korean-Wechsler Adults Intelligence Scale(K-WAIS) was administered and for measurement of executive intelligence quotient(EIQ), Executive Intelligence Test(EXIT) was administered. RESULTS: Of patients, 50.8% included at abnormal EIQ group. The patients of abnormal EIQ showed poorer full scale IQ(FIQ), performance IQ(PIQ) and in subscale that picture arrangement, digit symbol, digit span, block design, object assembly and comprehension were significantly different. In terms of relationships between K-WAIS and EIQ, FIQ and PIQ have positive correlation with EIQ. And in subscale, picture arrangement, digit symbol, digit span, block design, object assembly and comprehension show positive correlation with EIQ. CONCLUSION: This study suggest that MTBI patients with have normal range of general intelligence level may have deficit of executive function is common. The decline of FIQ, PIQ and some subscales of K-WAIS may suggest executive dysfunction in MTBI patients.

Uterine sarcomas are relatively rare tumors of mesodermal origin that constitute 2-6% of uterine malignancies. Uterine sarcomas include endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), malignant mixed m llerian tumor (MMMT) of both homologous and heterologous type, pure heterologous sarcomas, blood vessel sarcomas, and lymphoma. Endometrial stromal tumors are divided into three types: 1) endometrial stromal nodule, 2) low-grade stromal sarcoma or endolymphatic stromal myosis, and 3) endometrial stromal sarcoma. The low grade endometrial stromal sarcoma is very rare. It shows occasional local recurrence, which might arise from endometrial stroma, from adenomyosis, and rarely from endometriosis. We have experienced a case of low grade endometrial stromal sarcoma of the uterus in a 54-year-old woman, which is presented with a review of literatures.

BACKGROUND: It is well known that intracoronary thrombolysis during the early period of acute myocardial infarction leads to the limitation of myocardial necrosis, preserves left ventricular function, and improves survivals. The recanalization rate of intracoronary rrokinase infusion into infarct-related coronary artery was known as 62-94 percents in previos studies. The various factors influence the outcome of intracoronary thrombolysis, including total dose of urokinase, time from onsrt of chest pain to thrombolysis. The purpose of this study was to evaluate whether the occlusion site morphology influences recanalization rates of intracoronary thrombolysis. METHODS: We evaluated infarct-related coronary artery morphology of 56 acute mycardial infarction patients who performed intracoronary thrombolytic therapy within 6-12 hours after the onset of acute myocardial infarction. Intracoronary urokinase infusion was performed at a rate of 25000 IU/minute. The presence of calcification, collaterals, side branches and the stump site morphologies(thrombus type, pencil type, cutting type) were identified on magnified 35mm cine frames. RESULTS: Reperfusion was successed in 34 patients and failed in 22 patients. There were no statistically significant difference in the pressure of calcification, collaterals, and side branches between success and failure groups. Intracoronary thrombus was identified in 21 percent of success group, but not in failure group. The reperfusion rates according to stump site morphology were 76% in thrombus type, 58% in cutting type, and 42% in pencil type(p<0.05). CONCLUSION: Our study indicates the presence of intracoronary thrombus and the morphology of thrombus type is more effective in intracoronary thrombolysis in acute myocardial infarction. The identification of types of the coronary obstruction will be helpful for the selection of intracoronary thrombolysis in acute myocardial infarction patients. And the results suggest that the difference of stump composition show different stump morphologies.

The lack of sufficient oral mucosa available for intra-oral reconstruction has been dealt with by the use of skin or oral mucosa grafts harvested from donor sites but grafts requires more than one surgical procedures and could cause donor site morbidity. Many investigators have attempted to increase available soft tissue by tissue engineered skin or oral mucosa replacements for clinical applications. But, reconstructed mucosa by several methods have low physical properties such as rolling and contraction. The aims of this study were to develope an in vitro experimental model that maintains an epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally cultured oral mucosa embedded with Polydioxanone mesh by histological and immunohistochemical analysis. The results were as follows; 1. Oral mucosa reconstructed by three-dimensional organotypic culture revealed similar morphologic characteristics to equvalent normal oral mucosa in the point that they show stratification and differentiation. 2. The expression of cytokeratin 10/13 and involucrin in the cultured tissue showed the same pattern with normal oral mucosa suggesting that organotypic co-culture condition is able to induce cellular differentiation. 3. After insertion of polydioxanone mesh, increased tensile strength were observed. These results suggest that three-dimensional organotypic co-culture of the oral mucosa cell lines with the dermal equvalent consisting type I collagen and fibroblasts reproduce the morphologic and immunohistochemical characteristics similar to those in vivo condition. And increased physical properties by use of polydioxanone mesh will helpful for clinical applications.

BACKGROUND: Blunted perception of dyspnea, which may be related to the increased mortality, has been demonstrated in patients with a history of near-fatal asthma and in the elderly. OBJECTIVE: The purpose of this study was to evaluate the relationship between the perception of dyspnea and the severity of asthma. METHOD: Baseline spirometry and Borg score change(A Borg score) during breathing through an inspiratory muscle trainer were measured in 27 consecutive asthma patients and 11 normal subjects. RESULTS: The baseline Borg score was negatively related to FEV1 A Borg score was significantly lower in asthmatics than in controls at high level of loads. A Borg score was lower in severe asthma than in mild asthma. A Borg score was positively related to the baseline FEV1. Seventy-five percent of severe asthma, 62.5% of moderate one, and 9.1% of mild one showed impaired dyspnea perception. Dyspnea perception was related to age(r, = -0.49, p<0.001). CONCLUSION: Three quarters of patients with severe asthma showed impaired dyspnea perception to inspiratory resistive load. Dyspnea perception was related to asthma severity and age.
