1/60. Occupational allergic rhinitis and contact urticaria caused by bishop's weed (ammi majus).Bishop's weed (ammi majus) has been known to induce toxic phytophotodermatitis. We now describe IgE-mediated rhinitis and contact urticaria caused by exposure to bishop's weed in a 31-year-old atopic female florist. A skin prick-prick test with bishop's weed flowers gave an 8-mm wheal, and the bishop's weed-specific IgE level in the patient's serum was 9.7 PRU/ml (RAST class 3). In an immunoblotting experiment with the patient's serum, nine IgE-binding protein bands with the molecular weights 19, 34, 39-41 (doublet), 52-61 (doublet), and >67 (triplet) kDa were detected in bishop's weed extract. The patient became symptomless after she had ceased to work as a florist.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
2/60. Severe dermographism after topical therapy with diphenylcyclopropenone for alopecia universalis.We describe here a 19-year-old Japanese man with an 11-year history of alopecia universalis, who, after the 1st application of a 0.003% diphenylcyclopropenone (DPCP) solution to the whole scalp, developed acute contact dermatitis at the test site, together with widespread severe dermographism. Every 3 weeks, persistence of the severe urticarial reaction and efficacy of treatment were monitored by constant pressure stimuli in a series of pressure tests, and subsequently evaluated by laser Doppler flowmetry (LDF). Although, on pressure tests, the urticarial response was found to significantly improve after starting treatment, erythematous responses continued to appear for nearly 3 months. The persistent course of these side-effects in our patient strongly suggests that precautions must currently be taken in the therapeutic use of potent sensitizers such as DPCP.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
3/60. Drug-induced solar urticaria due to tetracycline.Solar urticaria is an uncommon disorder characterized by pruritus, erythema and whealing commencing within minutes of exposure to ultraviolet (UV) and visible light, and generally resolves in a few hours. We describe a 28-year-old woman who developed pruritus and erythema 5 min after sun exposure while on tetracycline for treatment of perioral dermatitis. Phototesting elicited urticarial reactions in the UVA, UVB and visible spectra. Repeat phototesting after cessation of tetracycline was negative. This report documents the first case of solar urticaria induced by tetracycline.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
4/60. Autoimmune progesterone urticaria.Autoimmune progesterone dermatitis is a rare cutaneous disorder characterized by recurrent and cyclic skin eruption with variable morphology, occurring during the luteal phase. A case of autoimmune progesterone urticaria in a 47-year-old woman is reported. An intradermal progestin test revealed a strong reactivity against this hormone. Treatment with tamoxifen and leuprolide acetate induced only a partial remission of urticaria. Bilateral oophorectomy was performed with absolute clearing of cutaneous lesions.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
5/60. Contact urticaria from rice.A 30-year-old man with atopic dermatitis had had erythema and itching of the hands after washing rice in water, though he had always eaten cooked rice without problems. Handling test with water used to wash regular rice was performed on abraded hands, and produced urticarial erythema after several minutes. Applications of water used to wash allergen-reduced rice were negative for urticarial reaction. Prick test with water used to wash regular rice was . However prick test reaction with water used to wash allergen-reduced rice was . histamine-release test of regular rice-washing water was grade 3 and that of allergen-reduced rice grade 1. In immunoblotting analysis with regular rice washing water, there were no bands with this patient. These results suggest that the allergen responsible for contact urticaria in this patient might be water-soluble, heat-unstable, and not contained in allergen-reduced rice.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
6/60. cheilitis caused by contact urticaria to mint flavoured toothpaste.A 26-year-old woman presented with a 12-month history of persistent dermatitis of the lips. She had failed to respond to cosmetic avoidance and therapeutic measures. Patch testing was negative, including her toothpaste and toothpaste flavours. She defied diagnosis until an acute flare followed immediately after dental treatment with a mint flavoured tooth cleaning powder. This led us to prick test her to mint leaves and this was positive. Her cheilitis settled after changing from her mint-flavoured toothpaste. A diagnosis of contact urticaria should be considered in cases of cheilitis of unknown cause.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
7/60. A case of jellyfish sting.Jellyfish sting may result in a wide range of symptoms from common erythematous urticarial eruptions to the rare box-jelly induced acute respiratory failure. In taiwan, with the increasing frequency of international travel, cases of jellyfish sting to foreigners are on the rise. We report a case of jellyfish sting with the rare presentation of painless contact dermatitis. A 38-y-o man accidentally stepped on a sea urchin with his right foot during scuba diving in a beach in thailand. Traditional therapy with vinegar was applied on the lesion. However, when he returned to taiwan, erythematous patches on the left thigh with linear radiations to the leg were discovered. The skin lesions had bizzare shapes and showed progressive change. No pain or numbness was noticed. Jellyfish stingwas suspected, topical medications were applied, and the patient recovered without complication. Jellyfish stings usually result in a painful erythematous eruption. In this case, though the lesion involved a large surface, there was no pain. delayed diagnosis of jellyfish sting was due to the atypical presentation and the physician's unfamiliarity to the Thai jellyfish sting. awareness to the wide spectrum of jellyfish sting symptoms should be promoted.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
8/60. Baker's asthma in a child.BACKGROUND: baker's asthma is a well-known occupational lung disease which usually develops in adults. We report the case of a two years old boy who suffered from asthma, urticaria and atopic dermatitis for twelve months, whose symptoms were associated to visits to his grandfather's bakery. methods AND RESULTS: skin prick tests (SPT) were made to dust mites, moulds, flours, alfa-amylase and egg. It was also determined total IgE and specific IgE antibodies to alfa-amylase and flours. Subsequently, a challenge test was carried out with wheat flour. The SPTs were positive to flours, alfa-amylase and egg. The determination of specific IgE antibodies showed 2.64 kU/L to wheat, 0.79 kU/L to glyadin and 2.98 kU/L to alfa-amylase. The patient developed asthma and rhinitis after manipulating wheat flour for 10 min. CONCLUSIONS: we demonstrated a type I hypersensitivity to wheat flour and alfa-amylase in a two years old child by SPT, specific IgE antibodies and challenge test. This case in the childhood equivalent of occupational baker's asthma.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
9/60. Occupational contact urticaria from diglycidyl ether of bisphenol A epoxy resin.BACKGROUND: Epoxy resin (ER) is a common cause of occupational allergic contact dermatitis (ACD), but contact urticaria from ER is very rare. methods AND RESULTS: A plastic-product worker first developed ACD from diglycidyl ether of bisphenol A (DGEBA) epoxy resin, and subsequent exposure resulted half a year later in contact urticaria: first with edema of the lips and eyelids, and later an urticarial reaction on the upper chest, with strong swelling of the eyelids and tightness of the throat. The diagnosis was based on a positive skin prick test to his "own" ER compound, a positive prick test reaction to DGEBA, and a positive skin provocation test with the ER compound and DGEBA. The contact urticaria test reaction was strongly aggravated when the allergen was wiped off with an alcohol solution, apparently because the solution enhanced the penetration of the allergen. CONCLUSIONS: Our case is of interest, first, because contact urticaria from ER is very rare, and second, because this is the second report in which a strongly intensified contact urticaria reaction was provoked by an alcohol solution. We suggest that if the contact urticaria provocation test with low-molecular-weight chemicals is negative, a contact urticaria provocation test with alcohol (CUPTA) should be performed.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
10/60. Rare systemic dermatologic reaction after pneumococcal vaccine administration.This case report describes a rare dermatologic reaction in a patient after administration of pneumococcal vaccine. A 65-year-old man developed an extensive dermatitis with pruritus, urticaria, and petechiae 1 week after receiving an intramuscular injection o the vaccine. The reaction resolved with application of topical steroids and oral diphenhydramine hydrochloride. This case report and others in the literature suggest the importance of recognizing the possibility of cutaneous adverse reactions with vaccines, such as the pneumococcal vaccine, which in general have a good safety profile.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
