, Soon-Hyo Kwon, Young Bok Lee, Hei Sung Kim, Jie Hyun Jeon, Gwang Seong Choi Treatment should be initiated for all suspected, clinical, or confirmed cases of scabies. Patients affected should be adequately isolated, and high-risk groups with close contact histories should be treated regardless of their symptoms. Optimal treatment strategies can be selected based on age, clinical subtype, and the patient's health status. In Korea, commercially available preparations for scabies treatment include topical 5% permethrin, topical 10% crotamiton, and oral ivermectin. Topical 5% permethrin is the first-line selective treatment for both classic and crusted scabies. Alternative treatments include topical 10% crotamiton and oral ivermectin. After completing treatment, follow-up visits at 2 and 4 weeks are recommended to monitor the therapeutic response. Treatment is considered to have failed if scabies mites or burrows are detected, new clinical characteristics develop, or there is an aggravation of pruritus. Scabies itch should be adequately managed with emollients, oral antihistamines, and topical corticosteroids. Preventive measures, including personal hygiene, patient education, and environmental control, should besd implemented to reduce the transmission of scabies.
, Woosung Lim Selenium is an essential microelement in animals including human. Selenium plays an important role in cellular functions such as deoxygenation and detoxification. Also, it can be used in treatment of cardiac disease, hepatic disease, AIDS and various cancers. Recent meta-analysis showed that high selenium exposure was associated with decreased risk of several cancers. Selenium has an effect on anticarcinogesis through several mechanisms, which are regulation of cell cycles, apoptosis, DNA damage and repair, inhibition of cellular adhesion and migration, anti-angiogenesis and immune modulation. Even though many laboratory studies have provided convincing evidence of these mechanisms, results from epidemiologic and clinical studies of selenium does not coincide with each other. Well-designed trials considering dosage and chemical form of selenium supplement as well as confounding factors and long-term follow-up of them would be needed to use selenium in chemoprevention and therapy of cancers.

Malignant neoplasm is the most common cause of death in Korea since 1988. In terms of incidence, still gastric cancer is the most common cancer in male, but breast cancer became the second most common female cancer followed by thyroid cancer. The reasons why incidence of breast cancer is increasing, (1) Westernized food patterns; high fat and high calorie diet, (2) late marriage with lower birth rate, (3) shorter period of breast feeding, (4) longer exposure to estrogen; early menarche with late menopause, hormone replacement therapy, (5) low physical activity with high body mass index, (6) environmental stress, and etc. Still incidence of breast cancer in Korea is relatively low comparing to those of American and European populations, but it is very rapidly increasing with annual increase rate of about 6%. So Korean breast cancer specialists should try to study breast cancer in terms of basic and also clinical aspect and also educate laymen for etiology, symptoms and signs, early detection method including breast self-examination and prevention.

, Kyoung Tae Noh, Ryung-Ah Lee, Kwang Ho Kim Cancer prevention by vegetable diet has received considerable attention in recent years. In the past these attributes of vegetables were based more on beliefs than on scientific evidences. But over the past few decades many studies have been performed about that. Cancer preventive components of many vegetables have been studied in experimental carcinogenesis models. These studies have reported on these components influence carcinogenesis during initiation and promotion phases of cancer development. Also, epidemiological studies and clinical trials have reported cancer preventive effects of vegetables. However, there is no comprehensive summary of cancer preventive effects with the types of vegetables. In this review, we classified the vegetables and described the mechanism of action of active components of vegetables, experimental studies, and clinical trials. Results revealed a negative correlation between consumption of vegetables and cancer risk. But we can't still conclude the effects of vegetables yet, so further studies would be necessary for final conclusion.
