Cephalosporins are well-known agents that may cause occupational asthma. There have been a few reports suggesting that its pathogenesis may be IgE-mediated. To the best of our knowledge, this is the first report of cefotiam-induced occupational asthma. A 36-year-old female, a nurse, visited our allergy department for the evaluation of occupational asthma. She had worked in the surgical inpatients`` ward and handled a few kinds of antibiotics for 4 years. At that time, she developed rhinorrhea, paroxysmal cough and chest tightness for 2 months. Her symptoms used to be aggravated during and shortly after her work and subsided several hours after work. However, her symptoms subsided spontaneously, because she was brought to the outpatients`` ward for recent 3 years. Therefore, she had only mild dyspnea on exercise. Methacholine bronchial challenge test revealed a negative response. The skin prick test with cefotiam (Fontaim(R)) showed a strong positive response and a specific bronchial provocation test with cefotiam demonstrated an early asthmatic response. A few days after bronchial provocation test with cefotiam, the methacholine bronchial challenge test showed a positive response. Further studies will be needed to evaluate the exact pathogenetic mechanism of cefotiam-induced occupational asthma. (Korean J Asthma Allergy Clin Immunol 2008;28:152-155)

Background: Recently, it has been demonstrated that the sensitization rate to two spotted mite (TSM, Tetranychus urticae) is as high as that to house dust mite (HDM) in respiratory allergy patients in the middle part of Korean peninsula. However, there are no published data on the sensitization rate to TSM in southern area of Korean peninsula. Objective: The aim of this study is to evaluate the sensitization rate to TSM in patients with allergic diseases in Busan area. Method: Skin prick tests were performed with 49 common inhalant allergens and TSM extracts on 519 patients with various allergic diseases between March 2005 and June 2007. We evaluated clinical characteristics and the sensitization rate to various inhalant allergens including TSM. Result: The sensitization rate to Dermatophagoides pteronyssinus (49.3%) was highest, followed by D. farinae (44.9%), TSM (32.9%), birch (17.0%) and mugwort (16.0%). Forty (7.7%) patients were sensitized to TSM only. Conclusion: TSM was the second most common sensitized allergen in patients visiting the allergy clinic in Busan area. These results suggest that TSM might be an important outdoor allergen in Korean peninsula. (Korean J Asthma Allergy Clin Immunol 2007;27:263-267)

In this study, the theoretical analysis focused on the quantity of liquid hydrogen required for cooling down to 20 K, as well as the generation of boil-off gas (BOG) from the cooling process of the cryogenic components. The study involved calculating the amount of liquid hydrogen needed to achieve the desired temperature for the cryogenic components and subsequently determining the resulting BOG production at various reference temperatures. It was shown that it was important to efficiently lower the temperature of cryogenic parts through preliminary cooling. As a result, the reference temperature and pressure had an influence on the BOG generation on the cooling of cryogenic components using liquid hydrogen.
