1/167. blister beetle periorbital dermatitis and keratoconjunctivitis in tanzania.Two cases of periorbital dermatitis and one case of keratoconjunctivitis following contact with blister beetle are presented. In tanzania and kenya the commonest blister beetle is known as Nairobi Fly and is of the genus Paederus. Ocular symptoms are common, usually secondary to transfer by the fingers of the toxic chemical involved from elsewhere on the skin. blister beetle keratoconjunctivitis has not previously been described in detail.- - - - - - - - - - ranking = 1keywords = dermatitis, contact (Clic here for more details about this article) |
2/167. Facial dermatitis, contact urticaria, rhinoconjunctivitis, and asthma induced by potato.BACKGROUND: Potato contains multiple heat-labile proteins which can induce immediate hypersensitivity reactions. Rhino-conjunctivitis, asthma, contact urticaria and protein contact dermatitis have been described in association with potato exposure. OBJECTIVE: A patient with possible airborne facial dermatitis to potato is described. RESULTS: A middle-aged atopic housewife with pre-existent atopic dermatitis suffered from rhino-conjunctivitis, asthma, and contact urticaria when pealing raw potatoes, but her main complaint was intense, treatment-resistant dermatitis of the face. The investigations showed a positive prick test, a positive patch test, and positive specific serum IgE to raw potato. Potato avoidance led not only to the resolution of the immediate symptoms, but also of the facial dermatitis, suggesting she had dermatitis due to this vegetable. CONCLUSIONS: Potato may induce contact dermatitis with positive immediate and delayed hypersensitivity tests.- - - - - - - - - - ranking = 2.2225185334563keywords = dermatitis, contact (Clic here for more details about this article) |
3/167. 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 = 1.4178595265343keywords = dermatitis, contact (Clic here for more details about this article) |
4/167. Facial orf.Orf is an occupational dermatosis caused by a poxvirus that infects sheep or goats. Human transmission typically occurs in people in contact with the infected animals or by handling contaminated animal products such as wool or meat. The infection in humans is classically characterized by a solitary papule on the fingers or hands. Involvement of the face or head has rarely been reported. We report orf in a young woman with multiple nodules on the face.- - - - - - - - - - ranking = 0.0038825057683333keywords = contact (Clic here for more details about this article) |
5/167. 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 = 1.4295070438393keywords = dermatitis, contact (Clic here for more details about this article) |
6/167. Occupational allergic contact dermatitis from unsaturated polyester resin in a car repair putty.BACKGROUND: Unsaturated polyester (UP) resins are widely used as cements in car repair painting to produce a smooth surface before the final painting. We report two car painters with hand and face dermatitis who were sensitized to a UP resin used for car repair cements. methods: Patch testing with commercial substances and ingredients and extracts from UP resins was used to verify the sensitivity. RESULTS: Both patients showed an allergic patch test reaction to a UP resin. They also had an allergic patch test reaction to diethyleneglycol maleate (DEGM), an extract of a UP resin. CONCLUSIONS: Both patients had been patch tested elsewhere with negative results because UP resins had not been used for patch testing. Accordingly, patients with dermatitis who have been exposed to UP resins need to be patch tested with UP resins. The specific chemical causing allergic contact dermatitis in our patients was DEGM.- - - - - - - - - - ranking = 1.413977020766keywords = dermatitis, contact (Clic here for more details about this article) |
7/167. 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 = 0.81242401845867keywords = dermatitis, contact (Clic here for more details about this article) |
8/167. Prolonged erythema after facial laser resurfacing or phenol peel secondary to corticosteroid addiction.BACKGROUND: Prolonged persistent erythema postprocedure using phenol or carbon dioxide (CO2) lasers occurs frequently and the reasons have not been fully ascertained. OBJECTIVE: To describe patients whose postoperative care consisted of prolonged use of topical corticosteroids and to assess the outcome of cessation of this medicine. methods: Twelve patients who underwent CO2 laser resurfacing or phenol peels to their face are presented. All patients were seen between 3 and 30 months after the procedures were performed. All dressings, wound care, and other medicaments had been stopped prior to being seen. Most were patch tested to a wide variety of chemicals including corticosteroids, topical medications, and preservatives. They were observed during the poststeroid cessation period and the clinical response is described. RESULTS: All patch testing showed insignificant results. All postpeel patients cleared within 6 months of steroid cessation, experiencing several flares of erythema before the end result. Three of the six laser resurfacing patients cleared fully within 12 months and three are still being followed. The erythema and severe burning in the patients that cleared stayed clear during long-term follow-up. No scars or atrophy were seen. CONCLUSION: The use of topical corticosteroid preparations postoperatively in peel and resurfacing patients is believed to be a major cause of prolonged erythema, dermatitis, burning, and telangiectasias in these patients. The mechanism is believed to be one of vasoconstriction/vasodilatation secondary to the corticosteroids through a nonintact barrier.- - - - - - - - - - ranking = 0.19922349884633keywords = dermatitis (Clic here for more details about this article) |
9/167. face dermatitis from contaminants on a mask for anaesthesia.Allergic and irritant contact reactions to face masks for anaesthesia have rarely been reported. We present a 55-year-old female patient who developed facial allergic contact dermatitis after an operation requiring general anaesthesia. patch tests showed positive reactions to cocospropylenediamin-guanidinium-diacetate (trivial name Dodigen 3558), a preservative used in disinfectants for medical instruments. It could be proven that residues of the causative allergen in the disinfectant adhered to the mask. This is the first report of a clinically relevant sensitization to this increasingly widely used agent.- - - - - - - - - - ranking = 1.0038825057683keywords = dermatitis, contact (Clic here for more details about this article) |
10/167. Allergic contact dermatitis caused by parabens: 2 case reports and a review.parabens, methyl, ethyl, propyl, benzyl, and butyl, are the most common preservatives in use today. They are the alkyl esters of p-hydroxybenzoic acid and are used extensively because they are relatively nonirritating and nontoxic and offer good antimicrobial coverage. Testing for paraben allergen can be done by patch testing. Two cases of allergic contact dermatitis (ACD) to parabens are used to discuss the background of parabens, their allergenicity, patch testing issues, and several "paraben paradoxes." Although ACD to parabens has been reported, given the widespread use, it is relatively uncommon. Because of their low rate of allergenicity and their favorable preservative profile and efficacy, parabens remain the number one preservative in use.- - - - - - - - - - ranking = 1.0155300230733keywords = dermatitis, contact (Clic here for more details about this article) |
