Hypersensitivity to cholecalciferol (vitamin D3) or its active metabolite, calcitriol, is an exceedingly rare clinical phenomenon, with only 2 previously reported cases of suspected immediate hypersensitivity. Diagnosis of delayed drug hypersensitivity reactions is inherently difficult due to the lack of any robust in vitro diagnostic assay, particularly in those patients for whom provocation testing confers an unacceptable risk. In these situations, diagnosis relies on reproducible clinical manifestations following administration of the culprit agent, resolution upon its withdrawal and exclusion of other potential differential diagnoses. Based on these criteria, we propose the first reported case of delayed hypersensitivity to cholecalciferol successfully managed with a desensitisation protocol to pure cholecalciferol.

Allergy to latex gloves has been described as an unusual complication during labor. However, IgE mediated hypersensitivity reaction to natural rubber have recently been identified as an international health problem. In this first case report in Korea, latex anaphylaxis during labor is described in an operating room nurse who has been continuously exposed to latex gloves. Because of the increasing frequency of latex allergy, obstetrician should take care and give more attention to the clinical history, as well as be aware of this possibility especially in high risk groups.

There have been few cases of albumin hypersensitivity reported, and there is limited information on this condition. When a patient is anaphylactic to a certain drug and no alternative drug is available to treat the underlying condition, desensitization is a reasonable option and can be performed successfully to treat the patient. A standard 12-step, 3-solution rapid desensitization protocol allows the safe readministration of a medication after certain types of immediate hypersensitivity. However, we demonstrated that a new 10-step, 1-solution desensitization protocol using antihistamine and leukotriene receptor antagonist as premedications, which was effective and safe in a patient with hypersensitivity. We report a 13-year-old boy with Gorham-stout syndrome who was presented with newly acquired albumin anaphylaxis and successfully treated with the 10-step rapid drug desensitization protocol.

Latex is the milky sap obtained by tapping the rubber tree, Hevea brasiliensis. The prevalence of latex allergy has been on the increase alongside the wider use of latex-manufactured products. The number of reports of latex-induced anaphylaxis during operation is therefore increasing. We report the case of a 56-year-old male patient who developed severe anaphylactic shock while under anesthesia when the tourniquet was deflated during elbow arthrolysis. A subsequent allergy workup revealed an IgE-mediated hypersensitivity to latex.

Rituximab is a monoclonal antibody used for the treatment of B-cell malignancies, including diffuse large B-cell lymphoma. Infusion-related hypersensitivity reactions to rituximab is well known, and delayed hypersensitivity reactions to rituximab are also reported. Desensitization is commonly used to prevent immediate hypersensitivity reactions, but recently there have been cases of successful desensitization therapy for delayed hypersensitivity reactions. A 66-year-old patient who underwent rituximab treatment for diffuse large B-cell lymphoma showed repeated rituximab-induced delayed hypersensitivity reactions with whole body rashes. Intravenous rapid desensitization was performed by using a 1-bottle, 11-step protocol for 6 cycles and thereafter hypersensitivity reaction did not recur. We herein reported a case of delayed hypersensitivity reaction caused by rituximab, which was successfully desensitized using our 11-step protocol.

The objectives of this study are 1) To review the published data and document the current knowledge on allergic manifestations to the fruit mango 2) To highlight the two distinct clinical presentations of hypersensitivity reactions caused by mango 3) To discuss the role of cross-reactivity 4) To increase awareness of potentially life threatening complications that can be caused by allergy to mango. An extensive search of the literature was performed in Medline/PubMed with the key terms "mango", "anaphylaxis", "contact dermatitis", "cross-reactivity", "food hypersensitivity", "oral allergy syndrome" and "urticaria". The bibliographies of all papers thus located were searched for further relevant articles. A total of 17 reports describing 22 patients were documented, including ten patients with immediate hypersensitivity reaction and twelve patients with delayed hypersensitivity reaction to mango. Ten of these patients (four with immediate reaction; six with delayed reaction) were from geographical areas cultivating mango, whereas twelve patients (six with immediate reaction; six with delayed reaction) were from the countries where large scale mango cultivation does not occur. The clinical features, pathogenesis and diagnostic modalities of both these presentations are highlighted. The fruit mango can cause immediate and delayed hypersensitivity reactions, as also "oral allergy syndrome". Although rare, it can even result in a life threatening event. Reactions may even occur in individuals without prior exposure to mango, owing to cross reactivity. It is imperative to recognize such a phenomenon early so as to avoid potentially severe clinical reactions in susceptible patients.

We report a rare case of anaphylaxis due to caffeine intake. A 27-year-old woman suffered her first episode of anaphylaxis and a positive skin prick test suggested that the anaphylaxis was due to an IgE-mediated hypersensitivity reaction to caffeine. She was diagnosed with caffeine allergy and has not had an allergic reaction after avoiding foods and drinks containing caffeine. Although caffeine is known to have antiallergic effects, this case shows that caffeine can be an allergen and cause anaphylaxis.

Allergic fungal sinusitis (AFS) is a noninvasive form of fungal rhinosinusitis resulting from an IgE-mediated hypersensitivity reaction. The diagnosis of AFS can be established by demonstrating type I hypersensitivity, presence of fungus in mucus, eosinophilic mucin, nasal polyposis, and characteristic CT scans. Although AFS is not unusual and its incidence may be increasing, few cases have been reported in Korea. Here, we report the first case of typical AFS in which Curvularia species was isolated by culture.
