  • 피부에 나타나는 난치성 질환인 백반증은 심리적인 위축감을 주어 정상적인 생활에 지장을 줄 수 있는 질병이다. 이에 따라서 본 연구에서는 피부에 나타나는 백반증의 진행 상태를 판단하기 위하여 L*a*b* 컬러 공간으로 변환된 피부 영상에 Otsu 임계값 설정 기법을 적용하여 백반증의 발병 영역을 자동으로 판별하는 알고리즘을 제안하였다.

  • The occupational skin diseases in an industry of silk reeling located in Daegu city of Korea were analyzed by inspection through a mass survey for improving the workers' health, November, 1975. The subjects, 177 persons were all females, and were distributed at 18-38 years old. About two thirds were under 25 years old. The meanage was 23.6 years. The incidence of skin diseases was about 53%. It was generally divided into three groups;- the epidermic changes of those were most frequent, 47.5%, the allergic reactions were 14.7%, and athlete's foot was only four cases, 2.3%. Most frequent signs of epidermic changes was the worn-out nail, 32.3%; and the keratolysis, 28.8%; and the callus, 15.3% were followed in order. Theses were significant in five per cent level between the sections of the silk reeling and the manufacturing;-Allergic reactions and worn-out nail were more frequent in the manufacturing group than the silk reeling, and keratolysis and callus were inverted proportionally. Allergic reactions were occurred within a few months from first entrance time, and it was more frequent in the group exposed to same allergen in the past than the continuing group from first. Most of the appearing sites of theses were hands, and infrequently, it was occurred in the face, neck, trunk, knee anfeet. These epidermic changes except allergic phenomena were appeared in the fingers, palmal and dorsal surface of hands frequently contacted.

  • Stevens-Johnson syndrome (SJS) presents with widespread blisters, erythematous or purpuric macules, and one or more mucous membrane erosions. Various etiologic factors, including infection, vaccination, drug administration, systemic diseases, physical agents, and food have been implicated as causes of SJS. Mycoplasma pneumoniae is the most common infectious agent to cause SJS in children. In recent literature, M. pneumoniae-induced SJS with mucositis that lacks the typical target lesions has been described. We report a case of a 6-year-old boy with swelling, peeling of the lips, and red eyes with photosensitivity. On physical examination, he showed severe oral mucositis and conjunctivitis with no evidence of skin lesions. Mycoplasma antibody, which was positive with titers of more than 1:2,560. For patients presenting with fever and mucositis of unknown origin, M. pneumoniae should be considered.
