1/157. Allergic contact dermatitis from propellants in deodorant sprays in combination with allergy to ethyl chloride.Allergic contact eczema from the use of deodorant sprays is sometimes caused by sensitization to the propellants. Positive reactions were seen in three patients when patch testing to Freon 11 (trichloromonofluoromethane). One patient also reacted to Freon 12 (dichlorofluoromethane). Another patient had an eczematous eruption after ethyl chloride was sprayed on the skin prior to taking biopsy. The two other patients showed strongly positive patch tests with this compound. Further investigations of the sensitizing capacity propellants with chemical resemblance have to be carried out to solve the problem of cross-sensitization.- - - - - - - - - - ranking = 1keywords = allergy (Clic here for more details about this article) |
2/157. Contact urticaria to the MCU-2A/P gas mask.A case of contact urticaria to the silicone rubber in the MCU-2A/P gas mask is presented. Contact urticaria is a type I hypersensitivity reaction mediated by immunoglobulin e that usually manifests as localized erythema, edema, pruritus, and urticarial plaques. It can also cause systemic reactions, including anaphylaxis. Allergic reactions to silicone rubber have been increasingly reported and are of importance in medical and military personnel. The implication of such a diagnosis in an active duty military member is significant because the individual cannot be worldwide-qualified. The correct diagnosis of allergic skin reactions to personal protective gear is critical to maintaining a strong fighting force and protecting military personnel from potentially life-threatening allergic reactions.- - - - - - - - - - ranking = 0.0060478472898481keywords = rubber (Clic here for more details about this article) |
3/157. Allergic contact dermatitis to acrylates in disposable blue diathermy pads.We report 2 cases of elicitation of allergic contact dermatitis to acrylates from disposable blue diathermy pads used on patients who underwent routine surgery. Their reactions were severe, and took approximately 5 weeks to resolve. Both patients gave a prior history of finger tip dermatitis following the use of artificial sculptured acrylic nails, which is a common, but poorly reported, cause of acrylate allergy. Patch testing subsequently confirmed allergies to multiple acrylates present in both the conducting gel of disposable blue diathermy pads, and artificial sculptured acrylic nails. We advocate careful history taking prior to surgery to avoid unnecessary exposure to acrylates in patients already sensitized.- - - - - - - - - - ranking = 0.25keywords = allergy (Clic here for more details about this article) |

5/157. Contact dermatitis due to nitroglycerin ointment.Topical nitroglycerin ointment is among the most effective long-acting vasodilators currently available. We report two cases of contact dermatitis in which patch testing showed allergy to nitroglycerin-containing compounds. The severity of this dermatitis necessitated the discontinuation of topical nitroglycerin therapy in both patients. A potent corticosteroid cream applied once to previous nitroglycerin application sites prevented or minimized this dermatitis and enabled continuation of topical nitroglycerin therapy. Contact dermatitis due to topical nitroglycerin preparations may be more common than is presently realized.- - - - - - - - - - ranking = 0.25keywords = allergy (Clic here for more details about this article) |
6/157. Allergy to lichens. Allergic contact dermatitis from usnic acid produced by lichenized fungi.Two forest workers affected with allergic contact dermatitis, which occurred only during work in forest areas, showed positive patch test reactions to lichens containing usnic acid and to isolated usnic acid. lichens are plants composed of fungi living in symbiosis with algae. Usnic acid, one of the lichenic acids which accumulates in lichenized fungi, is a monobasic acid with dibenzofuran structure and antibiotic properties. Dibenzofuran is chemically related to furocoumarans. lichens are plentiful in temperate zone forests and allergy to usnic acid represents some part of the "cedar-poisoning" problem in british columbia. Geographical distribution of lichens containing usnic acid suggests that allergy to usnic acid will be found to be more common than presently recognized.- - - - - - - - - - ranking = 0.5keywords = allergy (Clic here for more details about this article) |
7/157. Sensitivity to topically applied vitamin e.A search of the literature has not revealed any reports of allergic eczematous contact dermatitis due to the topical application of vitamin e. A case of contact allergy to synthetically produced alpha-tocopherol is herein reported. It is felt that this is a rare event in view of the fact that this vitamin is widely used topically in this country and abroad.- - - - - - - - - - ranking = 0.25keywords = allergy (Clic here for more details about this article) |
8/157. copper allergy from dental copper amalgam?A 65-year-old female was investigated due to a gradually increasing greenish colour change of her plastic dental splint, which she used to prevent teeth grinding when sleeping. Furthermore, she had noted a greenish/bluish colour change on the back of her black gloves, which she used to wipe her tears away while walking outdoors. The investigation revealed that the patient had a contact allergy to copper, which is very rare. She had, however, had no occupational exposure to copper. The contact allergy may be caused by long-term exposure of the oral mucosa to copper from copper-rich amalgam fillings, which were frequently used in childhood dentistry up to the 1960s in sweden. The deposition of a copper-containing coating on the dental splint may be caused by a raised copper intake from drinking water, increasing the copper excretion in saliva, in combination with release of copper due to electrochemical corrosion of dental amalgam. The greenish colour change of the surface of the splint is probably caused by deposition of a mixture of copper compounds, e.g. copper carbonates. Analysis by the x-ray diffraction technique indicates that the dominant component is copper oxide (Cu2O and CuO). The corresponding greenish/bluish discoloration observed on the back of the patient's gloves may be caused by increased copper excretion in tears.- - - - - - - - - - ranking = 1.5keywords = allergy (Clic here for more details about this article) |
9/157. orthodontic appliances made of organic polymer used in the metal allergic patient can withstand orthognathic surgery.We developed an orthodontic appliance completely made of organic polymer. The appliance was used for many years and proved very effective. It was used for the treatment of patients with metal allergy, and as a result, it is believed to be the best choice for treating metal allergies. In this report, we are presenting a surgical case with Class III malocclusion for a patient with metal allergy, and the concept of the appliance is briefly discussed.- - - - - - - - - - ranking = 0.5keywords = allergy (Clic here for more details about this article) |
10/157.
