  • Infantile atopic dermatitis(AD) may be developed by food allergens due to immature intestinal epithelium and its mechanism, which may have no clear-cut evidence, is thought to be IgE mediated immediate and late phase hypersensitivity. It is not easy to diagnose AD caused by food allergens exactly so it is likely to be underestimated more than it be. But we must consider it as a major factor of not only infantile AD but childhood and adult AD. We can see similar theory at previous Oriental medicine. Allergens can be transmitted to a fetus through the placenta and infantile AD is inflammatory condition by food allergens and immature function of intestines. So we must consider those factors at infantile AD treatment. We expect a new model of infantile AD treatment combining the conventional therapy with the diet therapy based on the Oriental medical theory.

  • Pollen-food allergy syndrome (PFAS) is an immunoglobulin E-mediated immediate allergic reaction caused by cross-reactivity between pollen and the antigens of foods-such as fruits, vegetables, or nuts-in patients with pollen allergy. A 42.7% prevalence of PFAS in Korean pediatric patients with pollinosis was recently reported. PFAS is often called oral allergy syndrome because of mild symptoms such as itching, urticaria, and edema mainly in the lips, mouth, and pharynx that appear after food ingestion. However, reports of systemic reactions such as anaphylaxis have been increasing recently. This diversity in the degree of symptoms is related to the types of trigger foods and the characteristics of allergens, such as heat stability. When pediatric patients with pollen allergy are treated, attention should be paid to PFAS and an active effort should be made to diagnose it.

  • The purpose of this study was to evaluate the effects of several types of bibimbab (a Korean traditional meal of mixed rice with assorted vegetables), on various immune activities. Compared to control animals in a mouse model (given hamburgers), the oral administration of a portion of bibimbab containing wild plants significantly increased splenic B/T, thymic Th lymphocyte subpopulations, serum IFN-${\gamma}$ production, and enhanced hemagglutination titers up to 300%. Also, a consumption of mushroom-bulgogi bibimbab and Jeonju-style bibimbab markedly decreased compound 48/80-induced systemic anaphylaxis (immediate hypersensitivity), while bibimbab with wild plants inhibited SRBC-induced delayed type hypersensitivity. These results suggest that bibimbab with wild plants both up-regulate on immune activities and have anti-allergenic properties.

  • Experimental studies were done to research the effects of the Ursi fel and the UDCA on the anti-allergic effects. The results were obtained as follows: 1) In the experimental effects of the Ursi fel and the UDCA on the vascular permeability responses to intradermal Serotonin, though both of the Ursi fel and UDCA revealed the significant effect, the Ursi fel had stronger effect than the UDCA. 2) In the provocative effects of the Ursi fel and the UDCA on the vascular permeability responses to intradermal Histamin, though both of the Ursi powfel and UDCA showed the significant effect, the Ursi fel had moreerful effect than the UDCA. 3) In the 48 hours homologous passive cutaneous anaphylaxis provoked by the IgE-like antibody against white egg albumin, though both of the Ursi fel and UDCA revealed significant effect, the Ursi fel had stronger effect than the UDCA. 4) In the delayed type hypersensitivity response to Picryl Chlorede, though both of the Ursi fel and UDCA were proved to be effective significantly the Ursi fel showed stronger effect. 5) In the delayed type hypersensitivity responses to Sheep red blood cell, the Ursi fel revealed the significant effect, though the UDCA has no significant effect. According to above results, the Ursi fel was approved it could be used widely as antiallergic drug for immediate and delayed type allergic diseases. Although the UDCA revealed efficacy in immediated type allergic diseases, it had less powerful effects than the Ursi fel and it showed no effects in some experiment of delayed type allergy, so it would be difficult to be used clinically.

  • Purpose: The clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies. Methods: The study included children <10 years of age with signs and symptoms indicative of immediate-type food allergies. Serum total IgE level was measured, and ImmunoCAP analysis for food allergens was performed. Results: The mean age of the study subjects was $1.6{\pm}1.6$ years (75 boys and 51 girls). Thirty-eight children (30.2%) were monosensitized and 88 children (69.8%) were polysensitized. Multivariate logistic regression analysis showed that the development of polysensitization to common food allergens was positively associated with a parental history of allergic rhinitis (adjusted odds ratio [aOR], 6.28; 95% confidence interval [CI], 1.78-22.13; P=0.004), season of birth (summer/fall) (aOR, 3.10; 95% CI, 1.10-8.79; P=0.033), and exclusive breastfeeding in the first 6 months of age (aOR, 3.51; 95% CI, 1.20-10.25; P=0.022). Conclusion: We found significant clinical differences between children with monosensitization and those with polysensitization to common food allergens and identified risk factors for the development of polysensitization in young children with immediate-type food allergies. Clinicians should consider these clinical risk factors when evaluating, counseling, treating, and monitoring young children with food allergies.

  • Adverse drug reactions are very common in clinical practice, and skin is one of the most frequent organs for adverse drug reactions. We report a case of a 71-year-old male patient who developed skin eruptions after switching formulation of quetiapine immediate release(IR) to quetiapine extended release(XR). He had been taking quetiapine IR(400mg/day) for treatment of manic episode which was developed one year ago. The patient showed great improvement of symptoms after taking quetiapine IR for about one year, thus dosage of medication was reduced to 50mg/day on the average. Unfortunately dose reduction has tended to worsen symptoms, so dose of quetiapine was increased again to 200mg/day with formulation changes to XR. Two days after he took new formulation, erythematous papules were occurred over his anterior neck and ventral side of left wrist. As he stopped quetiapine XR, the skin lesions gradually subsided. And he was successfully treated with readministration of quetiapine IR without any skin lesions.

  • The definition of anaphylaxis is 'a serious, life-threatening generalized or systemic hypersensitivity reaction' and is considered as the life threatening adverse drug reaction. We experienced a case of cefotetan induced anaphylaxis with negative pre-skin test, used for surgical prophylaxis. A 82-year-old female was scheduled for total knee replacement therapy. She had no previous history of allergy and her skin test results were also negative. On her right knee surgery, she underwent cefotetan therapy as a surgical prophylaxis for a week with no problems identified. Next left knee surgery, she also received the prophylaxis of intravenous cefotetan. However, a few minutes later, anaphylactic reaction developed with vomiting, severe hypotension, bronchospasm, and dyspnea. After immediate intensive care treatment, she recovered without significant complications. Though commonly used laboratory data in case reports, such as the specific IgE, tryptase, histamine, or allergic skin prick test were limited, we successfully confirmed anaphylaxis based on clinical criteria for diagnosing anaphylaxis based on WAO 2011 guideline with through concurrent patient°Øs medical history review and the process of identifying the causes.

  • Hyaluronidase, an enzyme that breaks down hyaluronic acid, has long been used to increase the absorption of drugs into tissue and to reduce tissue damage in cases of extravasation of a drug. With the increasing popularity of hyaluronic acid filler, hyaluronidase has become an essential drug for the correction of complications and unsatisfactory results after filler injection. For this reason, when performing procedures using hyaluronic acid filler, a sufficient knowledge of hyaluronidase is required. In order for hyaluronidase to dissolve a hyaluronic acid filler, it must interact with its binding sites within the hyaluronic acid. The reaction of a filler to hyaluronidase depends on the hyaluronic acid concentration, the number of crosslinks, and the form of the filler. Hyaluronidase is rapidly degraded and deactivated in the body. Therefore, in order to dissolve a hyaluronic acid filler, a sufficient amount of hyaluronidase must be injected close to the filler. If the filler is placed subcutaneously, injection of hyaluronidase into the filler itself may help, but if the filler is placed within a blood vessel, it is sufficient to inject hyaluronidase in the vicinity of the vessel, instead of into the filler itself. Allergic reactions are a common side effect of hyaluronidase. Most allergic reactions to hyaluronidase are local, but systemic reactions may occur in infrequent cases. Since most allergic responses to hyaluronidase are immediate hypersensitivity reactions, skin tests are recommended before use. However, some patients experience delayed allergic reactions, which skin tests may not predict.

  • Culture supernatants of splenocytes from C57BL/6 mice were exposed to 0.3, 1.0, and 3.0 ${\mu}g/ml$ cordycepin plus 3.0 ${\mu}g/ml$ lipopolysaccharide (LPS) to investigate the effects of cordycepin (3'-deoxyadenosine) on the production of inflammatory cytokines. Coadministration of 3.0 ${\mu}g/ml$ cordycepin with LPS in cultured murine spleen cells significantly diminished expression of the inflammatory cytokines tumor necrosis factor-${\alpha}$ and interleukin-6 (IL-6) in a time-dependent manner. Expression of the inflammatory cytokine IL-17A was substantially downregulated in a timeand concentration-dependent manner at all cordycepin concentrations. These findings suggest that cordycepin downregulates the immediate hypersensitivity reaction stimulated by LPS.

  • Aspergilloma and Allergic Bronchopulmonary Aspergillosis(ABPA) are different types of the pulmonary aspergillosis spectrum of diseases. ABPA is an inflammatory disease that causes hypersensitivity to Aspergillus spores growing in the bronchi, which is characterized by asthma, recurrent pulmonary infiltrations or mucoid impaction, eosinophilia and central bronchiectasis. Aspergilloma is a simple colonization of fungus within a cavitary lung lesion, but these diseases rarely coexist. A case of ABPA, coexistent with Aspergilloma, was experienced in a 31 year-old female. The diagnosis was confirmed by the immediate cutaneous reactivity to Aspergillus fumigatus, elevated total IgE antibodies, peripheral eosinophilia, bronchiectasis, growth of Aspergillus species in a sputum culture and radiographic infiltration. Treatment, with prednisone and itraconazole, led to improvement of the respiratory symptoms, reduction of the cavitary lesion and in the total serum IgE level.
