1/45. Perianal contact dermatitis caused by nail lacquer allergy.BACKGROUND: Allergy to nail cosmetics is relatively infrequent compared with other cosmetics. Allergic contact dermatitis from nail lacquer typically affects the eyelids, cheeks, sides of the neck, hands and periungual areas, and less frequently another areas. OBJECTIVE: We report on a patient who developed nail lacquer-related allergic contact dermatitis in an infrequent location, namely the perianal area. methods: A patient with perianal and eyelid pruritus and dermatitis was patch tested with the TRUE tests, cosmetic series, personal cosmetics, plastic and glue series, and personal nail lacquers. RESULTS: A 2 positive allergic response was observed at the sites of the toluenesulfonamide-formaldehyde resin and at the sites the patient's nail lacquers at days 2 and 4. CONCLUSION: Nail lacquer allergy may be observed at distant sites, and the perianal area may be involved more frequently than was previously thought.- - - - - - - - - - ranking = 1keywords = allergy (Clic here for more details about this article) |
2/45. Late-type allergy to the X-ray contrast medium Solutrast (iopamidol).In the past few years, there have been an increasing number of publications on delayed intolerance reactions, including rashes, following the use of X-ray contrast media. We report a patient in whom infiltrated erythema of the face and generalized maculopapular rashes occurred on 2 occasions, within 1 day, following the use of the X-ray contrast medium Solutrast (iopamidol) for coronary angiography. The allergological investigations for clarification included prick tests and patch tests using a series of contrast media, as well as individual intravenous provocation tests. We found the cause to be a late-type allergy to the active substance iopamidol contained in the contrast medium Solutrast. We found a concomitant cross-reactivity to the contrast media iopromid and iomeprol. All 3 contrast media represent the monomeric, non-ionic type.- - - - - - - - - - ranking = 1keywords = allergy (Clic here for more details about this article) |
3/45. Occupational protein contact dermatitis to cornstarch in a paper adhesive.BACKGROUND: Protein contact dermatitis is better known in food-service and health-care workers than in industrial workers. Cornstarch has seldom been a problem, although it can cause contact urticaria to glove powder. OBJECTIVE: To present the case of a paper-bag maker who developed severe occupational (protein) contact dermatitis within two-three hours after returning to work. She lacked any evidence of urticaria and demonstrated largely negative patch-test results. methods: Following a history of occupational exposure to a cornstarch-based adhesive, the patient was patch-tested to materials with which she had worked, which she contacted, and with which she had attempted treatment. Following patch testing, she was prick-tested to cornstarch, the principal ingredient in the adhesive. RESULTS: Patch testing was negative except for a very mild reaction to the adhesive. Prick testing to cornstarch was more severe than the histamine control. The test site became eczematous and remained so for more than ten weeks. Avoidance of cornstarch and the adhesive was followed by clearing. CONCLUSION: Workup for prominent occupational contact dermatitis without urticaria may sometimes require testing for type 1 allergy.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
4/45. Laboratory assistant's occupational allergic airborne contact dermatitis from nickel presenting as rosacea.A male laboratory assistant working in a metallurgical laboratory with airborne exposure to nickel dust developed highly pruritic, rosacea-like symptoms. The symptoms cleared within eight days without treatment when the patient was off work. Patch testing confirmed nickel allergy. Based on the patient's work and clinical history it was evident that occupational exposure to airborne nickel induced the highly abnormal rosacea-like symptoms, not previously reported from nickel.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
5/45. Photosensitivity to lomefloxacin. A clinical and photobiological study.Photosensitivity is an uncommon but characteristic side effect of quinolones, with a variable incidence for the different drugs. Several cases, considered either phototoxic or photoallergic, have been described with lomefloxacin use. During the last 4 years we studied 8 patients (mean age 69.4 years) with eczematous or acute sunburn-like lesions in photo-exposed areas, after taking lomefloxacin for a period of one week to several months. After drug withdrawal and systemic and/or topical corticosteroids, lesions cleared within one week to two months, with dischromia in one patient. Six to eight weeks thereafter, a photobiological study was performed. Minimal erythema dose (MED) for UVA and UVB were normal and photopatch tests with lomefloxacin, ofloxacin, ciproflaxacin and norfloxacin, tested at 1%, 5% and 10% in petrolatum and irradiated with 5 and 10 J/cm2 UVA were negative in 7 patients and 20 controls. Patient 1 had a positive photopatch test with lomefloxacin. One patient, who inadvertently reintroduced the drug before photopatch testing, developed a sharply limited erythematous reaction at 48 h in all irradiated areas, without aggravation at the sites of the quinolones patches. Our patients illustrate the polymorphism of clinical photosensitivity to lomefloxacin and represent the largest series in which photobiological studies have been performed. As in previous reports there are arguments favouring photoallergy, but phototoxicity appears to be the main mechanism of photosensitivity to quinolones, particularly in older patients with concomitant diseases and long-term use of the drug.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
6/45. asthma, rhinitis and dermatitis triggered by fungal infection: therapeutic effects of terbinafine.We report 2 atopic patients suffering from tinea unguium caused by trichophyton rubrum. In addition, both patients had symptoms of allergies: one had perennial rhinoconjunctivitis and bronchial asthma, the other had chronic dermatitis of the face and neck. In both cases, their allergy symptoms improved dramatically during oral therapy with the antifungal agent terbinafine (250 mg/day) and relapsed after its discontinuation.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |

8/45. An unusual acute urticarial response following microdermabrasion.BACKGROUND: Microdermabrasion is widely performed in a number of clinical settings, including medical offices, salons, and spas. This procedure is generally regarded as safe and easy to perform. OBJECTIVE: To determine if latex exposure caused an acute urticarial response following microdermabrasion in a latex-allergic patient. methods: The patient was prick tested to saline and histamine controls, latex, and sterile medical grade 100 m aluminum oxide crystals that had been passed through the microdermabrader. RESULTS: The strongly positive latex prick test confirmed latex allergy in our patient. Negative prick testing to aluminum oxide crystals that had passed through the microdermabrader make it unlikely that the patient was exposed to latex via this system. CONCLUSION: physicians need to carefully evaluate patients who are considering microdermabrasion and appreciate that unexpected serious complications can occur.- - - - - - - - - - ranking = 0.62401888133811keywords = allergy, latex (Clic here for more details about this article) |
9/45. Do monoterpenes released from feverfew (tanacetum parthenium) plants cause airborne Compositae dermatitis?The Compositae plant feverfew (tanacetum parthenium) is an important sensitizer in europe and has been suspected of causing airborne Compositae dermatitis. A previous investigation of substances emitted from feverfew plants detected no sesquiterpene lactones, however, but mainly monoterpenes. The aims of this study were to test whether feverfew-allergic patients were also sensitive to some of the above-mentioned monoterpenes and, if so, to study associations between sensitization patterns, relevance of feverfew allergy and clinical features. 17 patients with / reactions to feverfew and parthenolide were tested with 15 selected monoterpenes and 2 sesquiterpenes. Of the 17 persons, 13 had positive and/or doubtful positive reactions to 1 or more monoterpenes. Only 1 person was allergic to several monoterpenes. Her history of gradually worsening Compositae dermatitis culminating in a probable airborne dermatitis, mimicking photosensitivity, and the disappearance of symptoms upon removal of feverfew plants suggest monoterpenes as a possible contributing factor. Similar associations between doubtful positive monoterpene reactions and clinical patterns, fragrance/colophonium allergy and relevance of feverfew allergy were not established with certainty. In conclusion, sensitization to the sesquiterpene lactones of feverfew is not invariably accompanied by sensitization to its volatile monoterpenes. The presence of monoterpene allergy, however, may contribute to airborne Compositae dermatitis.- - - - - - - - - - ranking = 0.8keywords = allergy (Clic here for more details about this article) |
10/45. Occupational contact dermatitis to hydrangea.Two female commercial hydrangea growers, from separate nurseries, presented with similar hand and facial dermatitis. Both had a hand dermatitis affecting particularly the first three fingers and backs of both hands and complained of a recurrent facial dermatitis affecting the forehead, around both the eyes and bridge of nose. They related their dermatitis to their work. patch tests confirmed allergy to all components of hydrangeas including petal, leaf and stem. Avoidance resulted in resolution of their dermatoses. Allergy to hydrangeas has been reported previously although infrequently.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
