1.A Case of Toxic Epidermal Necrolysis.
Yeungnam University Journal of Medicine 1984;1(1):185-190
Toxic epidermal necrolysis is a reactive erythema of nonstaphylococcal origin characterized by a scalded appearance of the skin. The TEN is widely regarded as a variant of severe erythema multiforme because of its acute course, its freguent common cause, its freguent overlap with Stevens-Johnson disease, and its histologic identity. I present a case of TEN with severe mucosal involvement resembled Stevens-Johnson disease.

2.An Experimental Study on Effects of Renal Papillectomy and Partial Ureteral Ligation on the Kidney.
Korean Journal of Urology 1974;15(2):65-76
Necrosis of the papilla and chronic interstitial nephritis of the renal cortex are the two renal 1esions most commonly. described in cases of analgesic nephropathy. Some authors believed that the necrosis of the papilla was secondary to the cortical changes by which fibrosis of the cortex produced ischemia of papilla and necrosis. However, other authors have suggested that the pathogenesis is, in fact, the reverse and that the cortical changes in analgesic nephropathy are caused by the medullary necrosis. An experimental study was therefore undertaken to clarify this problem and also to determine the influence of increased intrapelvic pressure on the postpapillectomy renal alterations. Followings are the results: 1. In 'the group having renal papillectomy, marked tubular dilatation and interstitial edema of the medulla are prominent changes upto two weeks after removal of the papilla. Tubules are usu. ally filled with various casts. After three weeks, there starts the tubular atrophy and interstitial fibrosis with mil infiltration of inflammatory cells. The tubular atrophy and renal scarring become much severe and diffuse six weeks after papillectomy. but glomeruli remain relatively intact. 2. The degree of tubular changes and parenchymal scarring are assumed influential to the size of removed papilla. The tubular atrophy is prominent in distal convoluted tubules and collecting tubules, and the interstitial changes extend from the medulla to the cortex in the late stage. 3. Focal or scattered depositions of amorphous calcium or calcium oxalate are found in about one fourth of cases. 4. In the group having partial ureteral ligation a week after renal papillectomy, the tubular and interstitial changes appear earlier and are more remarkable than those of papillectomy alone. The inflammatory reaction is also more prominent, and conglomeration of glomerulus is noted in some instances of the later stage. The form of the renal scarring found in this experimental study closely resembles that seen in analgesic nephropathy in man. This findings support the view that the cortical lesions in analgesic nephropathy develop as a direct consequence of papillary necrosis and additional ureteral ligation enhances interstitial nephritic process. It is possible that the tubular atrophy and interstitial edema that develop shortly after removal of the papilla may produce cortical changes.

3.Perceived Powerlessness in Hospitalized Elderly Patients.
Journal of Korean Academy of Adult Nursing 2001;13(4):601-609
PURPOSE: The purpose of this study was to identify the degree of perceived powerlessness in hospitalized elderly patients of the medical and surgical unit. METHOD: The instrument for this study was the Powerlessness Behavioral Assessment Tool(Miller, 1983). The reliability of the instruments was .85. The data was analyzed by descriptive statistics, t-test, and ANOVA. RESULTS: The results were as follows; 1. The mean score of powerlessness was 35.02(SD=+/-9.24) in a range of 19 to 64, and the mean of powerlessness was total 1.84. Among 4 subscales, the highest score was in the area of verbal response (M=1.98), and the lowest score for powerlessness was in the area of daily activities(M=1.74). In all items, 'verbal expression of fatalism' showed the highest score(M=2.78), and 'verbal expressions of giving up' showed the lowest score(M=1.38). 2. There were significant differences in the level of powerlessness according to hospitalization experience(t=-3.03, p=0.006), medical treatment experience(t=.291, p=.004). Especially, there was significant difference according to the hospitalization experience of the hospital in all sub-scales. CONCLUSION: Based on these conclusions, nursing education for patient's diseases and treatment can be used for proper nursing intervention in reducing the level of powerlessness of hospitalized elderly.

6.Application of Gene Rearrangement Analysis for Diagnosis of Malignant Lymphoma.
Korean Journal of Pathology 1995;29(4):415-422
To evaluate the utility of gene rearrangement analysis, eight cases of malignant lymphoma, one case of Hodgkin's disease, two cases of angioiminunoblastic lymphadenopathy (AILD) and two cases of non-specific lymphadenitis were studied by immunohistochemical and genetic analysis. Southern blot analysis was perfon-ned by a using vacuum transfer system and a biotin labelled probe. This method was faster, safer, and more convenient than conventional methods. Gene rearrangement study showed rearranged novel bands in five of six cases of B cell lymphoma, in all cases of T cell lymphoma, and in all cases of AILD. No rearrangement of the B cell receptor(BCR) or of the T cell receptor(TCR) was seen in Hodgkin's disease or in nonspecific lymphadenitis. These results suggest that gene rearrangement analysis of BCR and TCR is a recommended method for the diagnosis of clonality in lymphoproliferative disorders. It would allow pathologists to differentiate lymphoma from polyclonal lymphoid proliferation and to provide information for cell lineage.

BACKGROUND: In tinea pedis, the response of treatment and prognosis are different according to clinical types. Positivity in KOH mount and causative agent in culture are also different. OBJECTIVE: Our purpose was to evaluate the clinical characteristics and mycologic findings of tinea pedis according to the clinical type. METHODS: A clinical and mycological study was conducted with 97 cases of tinea pedis among out patients examined for 7 months from June 1994 to December 1994 at Yeungnam University Hospital and Catholic Skin Clizic, Taegu, Korea. RESULTS: 1. Age distribution showed patients in their fourth decade to be most common. The ratio of male to female was 1.2: 1. The distribution of patients by clinical type was interdigital type, interdigital combined with hyperkeratotic type, interdigital combined with vesicular type, hyperkeratotic type, and hyperkeratotic combined with vesicular type, in descending order. One to five years was the most comrrion duration of tinea pedis. Duration of tinea pedis was the shortest in the vesicular type, otherwis was longer in hyperkeratotic type. Rate of family history of tinea pedis was 54.6%. The larger the size of family was, the higher the positivity in family history. The rate of coexistent dermatiophytosis with tinea pedis was 39.1%, and tinea unguium was the most common one. 2. The isolated dermatophytis were T. rubrum, 90.7%, T. mentagrophytes, 7.2%, and T. rubrum rnixed with T. mentagrophytes, 2.1%. T. rubrum showed an even distribution in all clinical types of tinea pedis whereas T. mentanophytes was isolated only in the interdigital type, vesicular type, and interdigital combined with vesicular type. T. rubrum mixed with T. mentagrophytes was isolated in the interdigital combine with vesicular type. Distribution of dermatophytes was relatively even arnong the age groups. T. rubrum showed a relatively even distribution in duration of tinea pedis, but T. mentagrophytes was isolated in tinea pedis with shorter duration.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin, Cutaneous angiosarcoma usually occurs on the scalp and face of the elderly and most frequently in the sixth and seventh decade. We presented a case of angicisarcoma in a 70 year old woman. The patient had a well-demarcated, 3 x 3cm sized, dark brownish-colored, ulcerative nodule on the vertex with hemorrhagic bulla on the right. temporal scalp. Histopathologic examination of the nodule showed a well differentiated tumor with irregular anastomosing scular channels lined by atypical endothelial cells in the dermis and subcutaneous fat. Immunohistochenlical study for factorVlll-related antigen was partially positive in tumor channels. She was treated by wide surgical excision but she expired 5 months after discharge from the hospital.
