Dermographism is an exaggerated triple response of Lewis and appears as a lineat wheal with a flare at a site in which skin is briskIy stroked with a firm object. The etiology and pathogenesis of dermographism are uncertain but passive transfer tests are sometimes poeitive. The active serum factor has been characteiized as Ig E in some patients. In this experimental study, we tried passive transfer of dermographism with the sera of the patients with dermographism. Twelve dermographic patients' sera were tested to fourteen normal healthy persons and two asymptomatic dermographic persons, total number of thirty nine cases. Only two recipients were passively transferred but they showed positive responses to all sera tested, two and three respectively. This result suggests that not only serum factor but also recipient's factor(s) may be concerned in passive transfer of dermographism.

We herein described a 27 year-old male who has been suffering from pruritic erythematous wheal and flare on sun-exposed areas, especially the midback for the past, ten months. The action spectrum of this patient was between 320 and 400 nm, .Passive and reverse passive transfer tests were negative. According to the classification by Harber et al, the current case seemed to belong to type II.

OBJECTIVE: To evaluate whether skin tests are suitable to predict the allergy reactions induced by Chinese herbal injections (CHIs). METHODS: The skin tests including skin prick tests (SPT), intradermal tests (IDT) and provocation tests including subcutaneous tests and intravenous tests were administered to 249 healthy subjects and 180 allergic patients for 3 CHIs, including ginkgolide injection, diterpene ginkgolide meglumine injection and Salvianolate lyophilized injection. The results of the provocation tests were used as the "gold standard" to determine the sensitivity and specificity of the skin tests. RESULTS: The results did not show any significant differences between the healthy and allergy groups in both skin tests and provocation tests (P>0.05). The specificities of SPT and IDT were 0.976 and 0.797, respectively, and the sensitivities of both SPT and IDT were 0. CONCLUSION Skin tests are insufficient to predict the likelihood of allergic reactions resulting from CHIs. (ChiCTR-CPC-15006921).

Solar urticaria is an uncommon disorder characterized by rapid development of urticarial reaction in areas of skin exposed to nonizing electromagnetic radiation. Herber and Baer classified solar urticaria into eight types on the basis of action spectrum and passive or reverse passive transfer ability. We report two cases of type ]g solar urticaria which were activated by visible light and negative in both passive and reverse passive transfer test.

We report a case of solar urticaria being activated by both UVA and visible radiation and positive in passive transfer test by visible light, which was treated with sunlight and UVA radiation. A short course of treatment with sunlight produced no benificial effect. UVA phototherpy produced a rnarked increase in the minirnal urtication dose by UVA but there was no increased tolerance to sun exposure.

BACKGROUND: Althogh drug euption refers to a common dermatological condition, there are numerous holdbacks on the diagnosis. OBJECTIVE: This study atternpts to define the clinical features and causavite drug of the patients with drug eruptions, and to evalarate the diagnostic value of various skin tests. METHOD: 130 patients with drug eruptions were reviewed clinically. In 54 patients, intradermal test, patch test, and scratch patch test were performed using suspected drugs. Result : The exanthematous eruption(53.0%), fixed drug eruptior.(29.2%), and urticaria(6.2%) were the common types of the drug eruption. The common causative agenst of drug eruptions were antibiotics/antimicrobials, antipyretics/NSAIDs, and CNS depressants. 28 paitients out of the 54 patients on skin tests with suspected drugs had positive results in at least one slinest. CONCLUSION: In our study, we were able to obtain somewhat meaningfi 1 results based on data from the combination of various skin tests.

Iodinated contrast media (CM) can cause immediate and late reactions. We treated a patient with a recurrent generalized maculopapular rash and a fever that occurred within two days of exposure to iodinated CM, iopromide (Ultravist(R)), for chest computed tomography. We performed skin testing including prick tests, intradermal tests, and patch tests. Our findings indicated a late skin reaction to Ultravist(R) in addition to cross-reactions to other iodinated CM such as ioversol (Optiray(R)), iohexol (Iobrix(R)), and iobitridol (Xenetix(R)). In this study, we report the case of a patient diagnosed with a late adverse reaction to Ultravist(R) in addition to cross-reactions to other iodinated CM.

Diagnostic methods for drug allergy include the patient's history, in vivo skin test, in vitro laboratory test, and provocation test. However, the history is often not reliable, procedures for in vivo and in vitro tests are not standardized, and provocation tests are sometimes harmful to patients. Generally, skin prick and intradermal tests are useful for immediate reactions; in contrast, patch test and delayed reading of both skin prick and intradermal tests are helpful for delayed reactions. A drug provocation test is the gold standard for both responses, and it is necessary to be aware of exact indications and contraindications with appropriate drugs, doses, and intervals. To date, several methods have been developed to detect culprit agents for drug hypersensitivity reactions, but they are neither completely well validated nor standardized. Based on this awareness and necessity, the Korean Academy of Asthma, Allergy and Clinical Immunology launched the Standardization Committee to review the international guidelines and the literature, and then developed the consensus report on the procedures and applications of diagnostic tests for drug allergy.

A 48-year-old woman, who had had tattoo on her eyebrows, was seen with pruitic erythematous indurated plaques on the tattooing sites. The skin react ion was begun to observe about 4 weeks after getting tattoo. Skin biopsy specimens from the indurated lesions showed granulomatous reactions. Intradermal tests by means of multiple pricks and patch test were done on her low back with the same tattoo dye and also 4 others available in Korea. Serial punch biopsy specimens were obtained from the sites of intradermal test at 2nd, 7th, 28th, and 56th day after intradermal test. Granulomatous reactions were found in the spiecimens taken at the 28th and 56th day.
