Immediate hypersensitivity to raw potato has been presented as one or a combination of wheezing, rhinorrhea, sneezing, contact urticaria and contact dermatitis. We experienced a case of contact urticaria caused by raw potato in a 25-year-old female patient with allergic rhinitis and conjunctivitis. She had experienced itching and generalized urticaria after application of raw potato on her face 10 years earlier. Allergy skin tests showed positive results to common inhalant allergens, including D. pteronyssinus, D. farina, ragweed pollen, mugwort pollen and several kinds of grass pollens, but showed a negative result to raw potato e×tract. However, the provocation test by applying raw potato on her forearm produced an immediate onset of contact urticaria with itching sensation. High serum-specific IgE to raw potato compared to normal healthy controls was detected by ELISA. We first report here in a case of raw potato-induced contact urticaria in Korea, which suggested an IgE-mediated mechanism. (Korean J Asthma Allergy Clin Immunol 2008;28:148-151)
다중채널 LED 백라이트를 위한 Capacitor-Diode 전류평형 회로
박성한(Sung-Han Park),정영진(Young-Jin Jung),홍성수(Sung-Soo Hong),한상규(Sang-Kyoo Han) 전력전자학회 2011 전력전자학술대회 논문집 Vol.2011 No.7
최근 저전력 소모와 얇은 두께, 무 수은, 다양한 색 표현력, 빠른 응답 속도 등의 다양한 장점을 가진 LED(Light Emitting Diode)를 광원으로 이용하는 LCD(Liquid Crystal Display) TV가 큰 주목을 받고 있다. 이러한 LCD TV의 화면을 균등한 휘도로 표현하기 위해 기존의 구동회로는 다 채널의 LED를 정전류로 제어하는 DC/DC 컨버터가 채널마다 각각 적용되었고, 이는 원가 상승 및 효율 저하의 원인이 되었다. 이를 해결하기 위하여 본 논문에서는 각 LED 채널에 적용되는 DC/DC 컨버터 없이 트랜스포머, 커패시터, 다이오드를 이용하여 모든 LED 채널의 정전류 제어가 가능한 저가격형 구동회로를 제안한다. 이는 전력변환 효율과 전력밀도를 획기적으로 개선할 수 있고 수동소자만을 사용하므로 높은 신뢰성을 확보할 수 있다. 본 논문에서는 제안된 회로에 대한 이론적 해석과 실험을 통해 제안 회로의 타당성을 검증한다.

Background: Amoxicillin is one of the broad spectrum antibiotics and is widely used in the treatment of various infective diseases. There are various forms of amoxicillin-induced hypersensitivity reactions including urticaria/angioedema, erythema multiforme and anaphylaxis. Objective: To observe the clinical features and evaluate the significance of in vitro testing of amoxicilin-induced hypersensitivity reactions. Method: We retrospectively reviewed medical records of patients diagnosed as having amoxicillin-induced hypersensitivity reactions from January 2002 to February 2007. Serum-specifc IgE antiboides to ampicilloyl (AMP) and amoxicilloyl (AXO) were determined using the immunoCAP Result: Sixteen subjects were enrolled in this study. Clinical features of amoxicillin-induced hypersensitivity reactions included erythema multiforme (n=6, 37.5%), urticaria/angioedema (n=4, 25.0%), anaphylaxis (n=3, 18.8%), maculopapular skin eruption (n=2, 12.5%) and fixed-drug eruptions (n=1, 6.3%). Six subjects had a high serum specific IgE to AMP and all anaphylaxis patients had a high serum specific IgE to AXO and/or AMP. Conclusion: These findings suggest that amoxicillin could induce various cutaneous manifestations in which the most common ones are erythema multiforme and urticaria/ angioedema. The serious reactions of anaphylaxis were noted in 18.8% of subjects in which IgE mediated responses to 2 antigenic determinants were involved. (Korean J Asthma Allergy Clin Immunol 2007;27:162-167)

Objectives : Posttraumatic stress disorder (PTSD) is classified as an anxiety disorder. PTSD occurrence is known to be increased in middle-aged and older people, female, and individuals with a previous history of psychiatric disorders, lower education levels, low socioeconomic status, and severely injured patients. Anxiety symptoms are also related to later development of PTSD. In this study, we investigate the influences of injury severity and sociodemographic factors on severe anxiety in PTSD patients with no previous history of psychiatric disorders. Methods : Forty-one PTSD patients without previous history of psychiatric disorders were recruited from the psychiatric clinic at Chosun University Hospital. Subjects underwent psychiatric and physical examinations including the Injury Severity Score (ISS), Beck Anxiety Inventory (BAI), and Korean-Wechsler Adult Intelligence Scale (K-WAIS). We defined severe anxiety as a BAI scores of 30 or more. Logistic regression analyses and multi-step model selection were applied to identify predictive factors for severe anxiety. Results : In univariate analysis, age, ISS, and socioeconomic status were found to be significant factors. Through multivariate logistic regression analyses and a stepwise model selection, we found the combination of age and ISS to be the best-fitted model for affecting severe anxiety in PTSD patients without a previous history of psychiatric disorders. Conclusion : Our findings suggest that the combination of age and ISS could develop severe anxiety in PTSD patients with no previous history of psychiatric disorders.
