The hyperimmunoglobulinemia E (Jobs) syndrome (HIES) is characterized by marked elevated levels of IgE, recurrent cutaneous and systemic staphylococcal infections, atopic-like dermatitis, and defective neutrophil chemotaxis. Three cases of HIES have been reported in Korea, but not in the dermatology literature. We report a case of HIES with cutaneous infections and MRSA (methicillin-resistant Staphylococcus aureus). A 15-month-old girl presented with intractable pruritic excoriated papular pustular skin lesions and multiple subcutaneous abscesses. Surgical drainage of the abscesses and a course of antibiotic treatment in addition to topical steroids for about 7 weeks resulted in a remarkable improvement. (Korean J Dermatol 1998;36(3): 482-486)

폐 목재 소각 보일러 배가스로부터 질소산화물을 저감하기 위하여 설치된 선택적촉매환원 공정의 시운전 중에 전단에 설치된 여과포의 일부 소실이 발생되었다. 여과포 소실에 따른 불완전 연소 가스는 2단으로 설치된 저온 탈질촉매 표면을 미연탄소로 침적시켜 촉매의 탈질 효율을 급격히 저감시켰다. 활성 저하의 원인 분석을 위하여 XRD, EDX, BET, TGA, SEM 등 다양한 특성 분석을 실시하였다. 재생 방법으로 산 세척, 초음파 수 세척, 공기 중 소성의 방법을 적용한 결과, 공기분위기에서 450℃로 2시간 소성하는 것이 최적조건 임을 밝혀내었다. 재생된 촉매는 2 cm × 2 cm × 10 cm(촉매 무게 10 g) Honeycomb 촉매 시료를 이용하여 활성을 측정한 결과 사용 전 촉매와 동일한 수준의 활성인 180℃에서 NOx저감 효율 100%를 나타내었다. A bag filter system was partially burnt down during a trial run of waste wood incineration boiler. This brought about unburned hydrocarbon which caused a rapid deactivation of low temperature SCR catalyst set up in two stage after the bag filter. The deactivated catalyst was investigated in order to trace the origin by several characterization methods such as XRD, EDX, BET, TGA, SEM. The deactivated catalyst was regenerated by different methods such as acid washing, water washing in ultrasonication, and calcination treatment under air condition. It is found the calcination treatment under air condition at 450℃ for 2 hours to be the best regeneration method. The catalytic activity was measured in the form of 2 cm × 2 cm × 10 cm (catalyst weight 10 g) honeycomb type. A deNOx efficiency of the regenerated catalyst showed 100% at 180℃ which is the same level of fresh one.

Background: There is growing interest in the role of complementary and alternative medicine (CAM) in treating patients with acne owing to an inadequate treatment response or adverse effects associated with use of conventional modalities to treat this skin condition. However, there is no literature available or reports of studies performed in Korea describing use of CAM in treatment of acne. Objective: To assess the usage and awareness regarding the role of CAM in the treatment of acne, among acne patients. Methods: A questionnaire was used to interview 159 patients with acne regarding their use of CAM for the treatment of acne. This survey was conducted in 1 tertiary medical center, 1 general hospital, and 2 dermatology clinics. Results: We found that 139 of 159 (87.4%) acne patients reported previous or current use of CAM. Among the 139 CAM users, acne-related cosmetics (71.2%) was the most frequently used category of products, followed by dietary therapy (58.3%), cleansing techniques, and a bath regimen (55.4%). Reportedly, the `Internet` (62.6%) was the most common medium used as a source of information regarding use of CAM. The most common reason for using CAM was reported as the `desire to try everything` (40.3%). Adverse effects related to the use of CAM were reported in 27 (19.4%) patients. The most common type of adverse effect reported was `aggravation of acne`. A majority of patients were not favorable for subjective therapeutic effect and satisfaction with CAM (60.0% and 84.2%, respectively). Conclusion: Our results indicate that a majority of acne patients use CAM with or without conventional treatment. Nonetheless, there is no study or evidence to prove the effectiveness of CAM in acne patients. Therefore, it is important for dermatologists to be aware of the risks and adverse effects associated with use of CAM for effective management of patients who consult them for treatment of acne.
