Bowen's disease is a premalignant condition, which may evolve into invasive carcinoma. Most invasive carcinomas arising from Bowen's disease show squamous differentiation, but rarely basaloid, pilar, pilosebaceous or sebaceous differentiation. We herein describe two cases of invasive carcinoma arising from Bowen's disease. First case, a 78-year-old male, presented with an erythematous plaque with ulcerated and fungating changes on his back. Biopsy specimen revealed Bowen's disease transformed into invasive squamous cell carcinoma. Second one, a 67-year-old male who had been diagnosed histologically as Bowen's disease on the right inguinal area 5 months ago, complained of enlargement and infiltration of the previous lesion. Biopsy specimen showed invasive carcinomatous change of basosquamous differentiation. Our cases represent unusual invasive changes of Bowen's disease into squamous cell carcinoma and carcinoma of basosquamous differentiation. (Korean J Dermatol 2000;38(6):777~780)

본 논문에서는 전자 문서 교환 시스템인 EDI에서의 정보보호 서비스를 제공하는 EDI 정보보호 시스템의 개발 기술 및 기반 기술에 대하여 언급한다. 이 시스템은 주로 ITU-T X.400 MHS 통신 프로토콜에 기반을 둔 X.435 EDI 정보보호 서비스를 제공함에 그 목적을 두고 있다. 이를 위해 X.509에 정의된 인증구조 및 보증서에 따른 공개키/개인키 쌍을 생성, 분배, 관리하는 키 관리 시스템을 개발하였으며, 향후 발생될 수 있는 분쟁에 대비한 보안 감사 추적 시스템도 개발하였다. 본 논문에서는 정보보호 서비스 처리시 발생하는 중복되는 작업을 최소화하고 사용 알고리즘을 언제든지 교체 또는 변경할 수 있는 시스템 구조와 기존 EDI 시스템의 최소변경만으로 정보보호 시스템 구축이 가능토록 하는 이식성을 극대화하는 정보보호 시스템 모델과 관리 방안을 제시하였다. In this paper, we address the design and the implementation technologies of security system for electronic data interchange(EDI). The purpose of this system is to provide security services with X.435 EDI system based on ITU-T X.400 message handling system(MHS) protocol. To achieve this purpose, we developed a key management system which generates, distributes, and manages a key-pair(public key and private key) according to X.509 authentication framework and certificates. And we developed a security audit system to provide against the controversy to which can be open hereafter. This paper presents the system architecture to be able to reduce the number of redundant service elements and to replace the used mechanisms and algorithms by any other good ones or its own ones at any time. Also, it describes the design model and the management method of a security system to be able to maximize a portability by building a system with the system modification, which almost never change the existing EDI system.

N/A Background : The bioengineering methods for investigating irritant skin reaction have been developed for several decades to evaluate the irritation potential more objectively and quantitatively and obtain the information which is not obvious by the visual examination. Objective : The purpose of this study was to compare the irritant skin reaction of three kinds of surfactants with various low concentrations which produce little reaction visually and investigative the threshold concentration that is reliable for a patch test. Also we investigated the sensitivity and the correlation between visual examination and bioengineering methods in four different concentrations of surfactants. Methods : Twenty healthy volunteers were patch tested with 0.01%, 0.05%, 0.1%, 1.0% of sodium laury1 sulfate(SLS), cety1 trimethy1 ammonium chloride(CETAC), POE(20) sorbitan monolaurate (Tween-20) on the flexor side of the Lt. forearm. The result of patch test was evaluated by visual scoring, evaporimeter, colorimeter, and corneometer until 72 hours. Results : 1. SLS, anionic surfactant, showed the highest irritation potential in visual scoring, TEWL, and skin color measurement. And CETAC, cationic surfactant, showed the greastest irritation in corneometer measurements than other surfactants. 2. TEWL was the most sensitive method for evaluation of skin irritation and correlated most closely with visual examination. 3. Concentration of surfactant higher than 0.1% showed to produce reliable and constant result of skin irritation as the experimental primary irritant. Conclusion : SLS is proved to be the most appropriate primary irritant for studying irritant contact dermatitis, and the degree and mode of skin irritation is different according to the concentration and kinds of surfactants. TEWL measurement is the most sensitive bioengineering method, which could detect early stages of irritation and correlate well with visual examination. (Korean J Dermatol 1999;37(9) : 1276∼1285)

A persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It is a persistent remnant of a vessel that is present as a counterpart of normal right-sided superior vena cava(SVC) in early embryological development but normally disappears later. Its diagnosis can be confirmed by many noninvasive and invasive tests, or it is incidentally diagnosed at insertion into the left subclavian or jugular vein or thoracic surgery. If it is not associated with other congenital cardiac anomalies, it is usually asymptomatic and hemodynamically insignificant. We describe the chest radiograph and CT findings of bilateral SVC with drainage to left superior intercostal vein, hemiazygos, azygos vein and right SVC, and no connection of coronary sinus.

Backgroud: There were no effective methods to monitor the treatment of leprosy. Anti-PGL-1 ELISA test and polymerase chain reaction (PCR) were used for monitoring the treatment, however many restrictions have been found to apply to those methods in the field. Bacillary index (BI) is a popular and not an expensive method. For this reason, the exact data to assess the efficacy of the standard multi-drug therapy (MDT) with BI is required for evaluation of the treatment in Korea. Objective: The purpose of this study was to clarify the change of bacillary index during MDT in multi-bacillary leprosy (MB) cases. Methods: A total of 72 patients in the National Sorokdo Hospital were included in this study. With the retrospective method, BI, type of leprosy, relapse, age, and duration of treatment were evaluated. Results : The results were as follows; 1.In this study, the mean duration of BI changing from 6 to 5 was 5.7 months, from 5 to 4 was 6.6 months, from 4 to 3 was 13.1 months, from 3 to 2 was 13.8 months, from 2 to I was 12.4 months, from 1 to 0 was 29.4 months. 2. The time of initial change of BI after MDT were as follows : within 3 months(26.4%), 4-6 months(29.2%), 7-12 months(26.4%), 13-18 months(8.3%), 19-24 months(4.2%), 25-48 months(5.5%). The mean duration was 8.9 months. 3. The mean cumulative time of BI to 0 was 68.4 months Conclusion: These results suggest that after MDT, in most of MB, BI decreased within one year and it took 68.4 months for BI to be 0. At first, BI decreased relatively fast, however a longer period was required to become a state of BI 0.

Eosinophilic pustular folliculitis(EPF) is a rare inflammatory follicular disorder of unknown etiology. EPF is characterized by recurrent clusters of pruritic, follicular, sterile papules and pustules on the seborrheic area of young men. Compared with classical adult type, infantile EPF reveals the distinctive clinical features, such as constant involvement of the scalp, self-healing recurrent crops, and the possibility of lasting until 3 years of age. We describe two patients with infantile EPF. Both patients commonly had recurrent crops of papules and pustules affecting the scalp only. Bacterial and fungal cultures were negative, and one patient showed an eosinophilia. Biopsy specimens revealed folliculitis with a predominant eosinophilic infiltrate. Clinical response to oral antihistamines and topical corticosteroids was noted, but the lesions have been recurrent during the long-term follow-up period of 1 year.

Elastofibroma is a rare disease which presents as a slowly-growing, solid, ill-defined fibroelastic mass occuring almost exclusively in elderly women and arising mainly from the connective tissue between the lower part of the scapula and chest wall. Of the 270 cases of elastofibroma which have been reported, 170 cases had developed in Japanese patients. Despite the fact that there have been only two case reports in Korea, there might be a higher prevalence of elastofibroma in Korea than expected because of geographical similarity. We experienced a case of elastofibroma occurring in a 56-year-old man. To our knowledge, this is the first case report of elastofibroma in Korean dermatologic of literature.
