A Case of Erythema Multiforme A ssociated with Malignant Lymphoma Un Cheol Yeo, M.D., Kwang Hyun Cho, M.D., Yoo Shin Lee, M.D., Dae Seog Heo*, M.D., Seoung Chul Lee**, M.D Department of Dermatology and Internal Medicine*, College of Medicine, Seoul National University, Seoul, Korea, Department of Dermatology**, College of Medicine, Inha University, Kyung Gi Do, Korea We report a case of erythema multiforme associated with malignant lymphoma. Fifty-six-year-old male patient visited our clinic complaining generalized skin lesions which were compatible with erythema multiforme clinically and histopathologically. The skin lesions were treatment-resistant, recurrent and persistent for 3 years. In consideration of old age, atypical features of erythema multiforme and no other demonstrable etiology of erythema multiforme, we studied for internal malignancy. Malignant lymphoma at the duodenum was revealed by UGI series, abdominal CT, and endoscopic biopsy. After chemotherapy, the tumor mass and active skin lesions were cleared simultaneously. Erythema multiforme may be regarded as one of the paraneoplastic syndromes.

this study was attempted to examine how much our public sports facilities have been operated, meeting their purposes and suggest a future improvement plan centered on the privatization by literature review and analysis on practical data of our national public sports facilities. Unless it is clearly reestablished whether the government is to convert the functions of public sports facilities into those of profit facilities or to leave public sports facilities as they are, an attempt to privatize them at the level of a local autonomous body must invite danger of just making the identity of the functions of public sports facilities ambiguous. Focused on such point, a privatization plan was suggested in two aspects in this study - public service offering and profit creation.

Children's place making was analyzed in neighborhood environments of an apartment site. Open-ended interviews of 34 children, behavior observations of children in neighborhood spaces, and behavior mapping of the places were performed to investigate what were the neighborhood places important to children's everyday life, how they emerged, and what meanings these places had to the children. Ten different places were mentioned as important setting in their neighborhood. These places coincided the locations where behavior observations showed the children were engaged in neighborhood activities most often. This indicates that place and activity correlate. These places were important because they provided settings for social contacts/interactions (including meeting friends), recurrent habitualized activities (including plays), and memories of past events. Important also were physical conditions that helped the children have these experiences. Overall, the analysis indicates that activity is the most important aspect of the place experience, along with friends and play colleagues to share the activities, memories of past events associated with the places, and physical properties of the places supporting the activity experience.

This paper presents a new algorithm which is applicable in designing a smart damping system for vibration mitigation. The algorithm, which is extended into a unified system from Lyapunov stability theory, enables us to decrease the Quantization errors by its increased stability. The validity of this design method was proved in the numerical simulation on a control model of three-storied building structure. Smart damper was used for MR(magnetorheological fluid) damper in the numerical model, and its control effectiveness was evaluated. In order to make a more accurate control model numerical1y, we updated the model on the basis of the analysis of dynamic characteristics of structure and of the numerical analysis of a lumped mass model, and then adopted a state space model redefined by structural property matrix. Using this improved control model, control effect on structures which were under the influence of each different earthquake magnitude was analyzed with various performance index, and thus the algorithm presented here is proved to be valid.

This study attempted to determine the degree of asbestos release from the aging slate roof by comparing the asbestos content in the slate roof rain gutter with a colored steel plate (tin plate) over the slate roof. Four slate roof houses located in Haengmok-ri, Asan-si, Chungcheongnam-do, and one house constructed with a colored steel plate on the slate roof were selected to collect the sediment of the roof rain gutter. The asbestos fiber content was calculated by a point counting method using a polarization microscope after pretreatment with conversion treatment and hydrochloric acid treatment. The average asbestos content of the four slate roof rain gutter were 1.89%. However, asbestos was not detected in the Slate covering roof rain gutter, which were constructed on the slate roof. Asbestos fiber content was the highest at 2.89% in the slate roof rain gutter installed in 1976, followed by 2.44% in 1953. From the above results, it is necessary to minimize secondary damage as asbestos fibers released from slate roof houses to the surrounding atmosphere or leaked from slate roofs as rainwater may cause soil pollution and seriously affect residents' health. Although covering with colored steel plates (tin plates) has been shown to prevent the leakage of asbestos fibers to some extent, it is believed that a policy alternative to remove the slate roof as soon as possible is needed to solve the fundamental problem.

Primary unruptured appendiceal mucocele is a rare disease. It is very difficult to diagnose preoperatively because of the rarity of classical symptoms and low incidence. Usually it is discovered incidentally during abdominal ultrasonography(US), computed tomography(CT), or appendectomy for acute appendicitis. If untreated, one type of mucoceles may rupture producing a potentially fatal entity known as pseudomyxoma peritonei, therefore preoperative diagnosis is very important. With the advent of colonoscopy, abdominal US and CT, it has been possible to preoperatively diagnose mucocele of appendix. We experienced a case of appendiceal mucocele in a 60 year-old woman who had symptoms of lower abdominal discomfort and right lower quadrant abdominal pain, and it was diagnosed preoperatively by colonoscopy, abdominal US and CT. So we present this case with review of literature.

Small cell carcinoma(also known as oat cell carcinoma) of the urinary bladder is an extremely rare malignancy and is derived from neuroendocrine stem cells. It is usually biologically aggressive tumor with early vascular and muscle invasion, so it has poor prognosis. Radiological findings of small cell carcinoma are similar to other malignancies of urinary bladder, therefore it is impossible to distinguish small cell carcinoma from other malignancies. Pathologic study is an only useful method for differential diagnosis of bladder tumor. We report here the case of 74th years old woman presented with painless gross hematuria.

For the patient with stenosis of upper digestive tract caused by either benign or malignant process, esophageal dilatation is an important therapeutic modality. We reviewed retrospectively 39 cases treated by Savary-Gilliard dilatation for upper digestive tract stenosis, and results were follows : (1) Dysphagia was improved in 95% of the patients. (2) Eight patients(20%) sufferd perforation, five of them were managed with conservative medical measures, others were managed operatively. (3) In the cases with benign stenosis dysphagia was not noticed for 8.8 months, but with malignant stenosis dysphagia was reappeared after 2.8 months despite concomitant chemoradiotherapy. In conclusion, Savary-Gilliard dilatation was an effective measure for symptome due to upper digestive tract stenosis, but more careful attention for perforation should be necessitated. Also another therapeutic modality for treatment of malignant stenosis was inevitable.

A 40-years-old woman was admitted to this hospital with flank pain and high grade fever for 2 weeks. As a matter of her past history, extracorporeal shock wave lithotripsy (ESWL) was performed for treatment of renal stones 5 years ago. Her abdominal CT findings were hydronephrosis with pyonephrosis and renal stones. Antibiotics administered for 5 days had no effects on her symptom improvement. A right ureteral stricture was noticed by ultrasonography follow up. We inserted double J stent and continued antibiotics therapy for 10 days, and then her fever was disappeared and flank pain was improved. ESWL is one of the most important treatment of renal and ureteral stone. However, its complications should not be negligible including bleeding, pain, ureteral obstruction, infection and so on. Complications of ESWL can be divided into acute and chronic courses. When we treat pyelonephritis patient with past history of ESWL, possibility of ureteral stricture must also be considered. In this study we report a case of pyelonephritis caused by ureteral stricture, possibly as a chronic complication of ESWL performed 5 years earlier
