Eosinophilic gastroenteritis is an unusual disease characterized by eosinophilic infiltration of gastrointestinal tract, peripheral eosinophilia, and gastrointestinal symptoms. There are mucosal, muscular, and subserosal types, of which the subserosal type is the rarest. We experienced a 32-year old male patient with the subserosal type of eosinophilic gastroe-nteritis, who was presented with abdominal distension. The ascitic fluid revealed increased eosinophil count. With oral prednisolone, diarrhea and ascites rapidly disappeared and eosinophils in peripheral blood returned to normal. We report this case with a review of relevant literature.

Solar urticaria is a rare disorder in which immediate erythema and wheals are induced by ultraviolet or visible irradiation. This condition usually occurs in the third and fifth decades of life and is very rare in childhood. A 3-year-old girl presented with a history of an erythematous rash which had occurred on the face and neck, immediately after exposure to sunlight for one month. A diagnosis of solar urtiacria was made on the clinical reviews and phototest. Other photosensitive disorders could be excluded by the clinical and laboratory findings. She was treated with ketotifen and sun protection showing good early results.

Episodic angioedema with eosinophilia was described by Gleich, et al. as a distinct entity characterized by recurrent angioedema, urticaria, leukocytoeis with remarkable eosinophilia, fever and periadically increased body weight. Since then, several cases of this disorder have been reported in the United States, Europe and Japan. We present a Korean patient whose clinical, histopathologic, and laboratory findings are consistent with the syndrome of episodic angioedema with eosinophilia. This case supports the previous study that revealed some differences between Asian and Caucasian patients.

Acute eosinophilic pneumonia(AEP) was first described in 1989 and represents a clinical entity distinct from chronic eosinophilic pneumonia. AEP is characterized by acute respiratory insufficiency, hypoxemia, fever, diffuse radiographic infiltrates, and eosinophilia in bronchoalveolar lavage fluid or lung biopsies in the absence of infection, atopy, or asthma. Rapid response to corticosteroids is characteristic. We experienced a 47-year-old metal driller presenting typical clinical and radiological characteristics of AEP. We confirmed eosinophilic pneumonia with brochoalveolar lavage analysis and transbronchial lung biopsy. We report a case of AEP diagnosed by clinical, radiographic, and histologic findings with a brief review of the literature.

Background and OBJECTIVE: There has been a few case reports of anaphylaxis due to honeybee in Korea. In order to observe the clinical feature of bee sting anaphylaxis. Moderials and methods: Six patients living in Kyunggi province area were referred under history of anaphylaxis after the bee sting. Atopy was defined by skin prick test result to common inhalant allergen. Serum specific IgE antibody to each bee antigen was detected by radioimmunoassay to identify the causative bee. RESULTS: All six cases were female. Three had atopy and four had combined allergic diseases such as allergic rhinitis, asthma, and urticaria. The etiologic bees consisted of yellow jacket (6 cases), paper wasp (4 cases), yellow hornet (3 cases), white faced hornet (1 case) and honey bee (1 case). Four cases had experienced anaphylaxis after ant bite and they showed positive result on specific IgE to imported fire ant. Specific immunotherapy against causative bee venom was begun using bee venom extracts from Bayer (USA) based upon results of specific IgE anti-body to bee venom. CONCLUSION: The yellow jacket is the most common cause of bee venom anaphylaxis in this area. Further studies will be needed to evaluate possible cross-reactivity between bee and ant venom.

BACKGROUND: Although occupational asthma is defined as a reversible airway obstruction causally related to exposure in the working environment, many occupational asthmatics complain of asthmatic symptoms despite avoidance of the causative agent. Subjects and methods. Twenty-nine patients with occupational asthma who had been confirmed by specific bronchial challenge with reactive dye or isocyanates and had avoided the causative agent for at least 6 months were included in this study. A questionnaire about asthmatic symptoms and medication requirements, a lung functiontest, and a methacholine bronchial provocation test were performed. RESULTS: Asthmatic symptoms at follow-up were remitted in seven (41.2%) isocyanate-induced asthmatics, but none with reactive dye-induced asthma were remitted. At follow-up, the symptom-medication score and FEV1 were significantly improved in isocyanate-induced asthmatics than in those with reactive dye-induced asthma, but the geometric mean of PC20-methacholine was not different between the two groups. Among 17 isocyanate-induced asthmatics, a duration from symptom onset to avoidance was significantly shorter in the remission group than in the nonremission group, although the symptom-medication scores, FEV1 (% predictive value) and logPC20-methacholine at an initial diagnosis, and follow-up period defined as duration from avoidance to follow-up, showed no difference between the two groups. CONCLUSION: The outcome of occupational asthma may be determined by the causative agents and the duration from onset of asthmatic symptoms to avoidance.

BACKGROUND: Few studies have demonstrated an enhanced skin responsiveness to opiates in atopic subjects. OBJECTIVE: To determine whether the skin response to morphine is increased in atopics and to assess the clinical usefulness of morphine skin prick test in diagnosis of allergic diseases. METHOD: Allergy skin prick tests were performed using 55 common allergens, histamine, and morphine in 158 patients with allergic diseases. RESULTS: Wheal and flare sizes for morphine (1mg/mL) were significantly related to and smaller than those for histamine (1mg/mL). Although the proportion of subjects with allergic rhinitis and the level of serum total IgE were not different between responders (wheal >- 2mm) and nonresponders to morphine, the positive response rate to allergens was significantly lower in nonresponders. The flare sizes for morphine were significantly higher in positive allergen test group (A/H ratio >- 0.5). Among positive allergen test group, the subjects with atopy score >- 5 showed a larger flare size for morphine than those with atopy score < 5 while the sizes for histamine were not different. CONCLUSION: Morphine skin prick test is helpful for detecting false negative responses to allergens, and morphine skin test responses are increased in highly atopic patients probably due to enhanced mast cell releasability.

OBJECTIVE: To investigate the prevalence of airway hyperresponsiveness induced by isocyanate at one petrochemical industry complex in Yeochon, Korea. METHOD: Questionnaires, allergic skin prick test, toluene diisocyanate (TDI)-specific IgE, and non-specific airway hyperresponsiveness (AHR) were studied in 73 exposed workers and 27 control subjects. Methacholine challenge tests were done and bronc hial responsiveness (BR index) was defined as log (% fall of FEV1)/ log (last concentration of methacholine +10). RESULTS: Twenty-three workers (31.5% ) had respiratory symptoms, 21 had nasal symptoms, and eight had skin symptoms. Exposed workers with respiratory symptoms (n=22) had significantly higher BR index than those without them (0.82+/-0.06 vs 0.60+/-0.02, p<0.05). Exposed workers tended to have higher BR index than controls (0.67+/-0.03 vs 0.62+/-0.02). Three exposed workers had PC20 methacholine <2.0 mg/ml. There were no significant differences in atopy score between exposed workers and controls (p>0.05). Specific IgE antibodies were found in 19.7% of exposed workers. FEV, showed a significant negative correlation with BR index (r =-0.25, p<0.05). Poor correlation was noted between BR index and atopy, smoking status, or exposure duration. CONCLUSION: These findings suggest that workers exposed to isocyanates are at higher risk of airway hyperresponsiveness.

BACKGROUND: It is known that HLA molecule can restrict specific IgE responses, but few studies have documented the association between HLA and sensitization to house dust mite(HDM). OBJECTIVE: To evaluate whether a specific HLA type can be a risk or protective factor for the development of HDM sensitivity. METHOD: Total 146 subjects were genotyped for HLA-DRB1 using PCR-SSP technique and HDM sensitivity, determined by skin prick test using two mite allergens, D. pteronyssinus (Dp) and D. farinae (Df). Subjects were grouped according to Dp or Df sensitivity and linkage analysis between HDM sensitivity and HLA-DRB1 genotype was performed. RESULTS: The data revealed higher allele frequencies of DRB1*07 in Dp or Df sensitive groups compared to insensitive groups (11.6% vs. 2.6% in Dp, 11.5% vs. 3.3% in Df group, p<0.05), but the other allele frequencies showed no difference. CONCLUSION: There was a significant association between HLA-DRB1*07 genotype and HDM sensitization. These results indicate that antigen presentation by HLA class II molecule restricts the development of specific IgE response to HDM.
