A 42-year-old woman presented with a hypersensitivity reaction after the ingestion of a small amount of fresh mango gelato. She developed itchy palpable purpuric lesions over her arms, legs, neck and abdomen 4 days after ingestion. The lesions persisted for 5 weeks despite treatment with betamethasone-17 valerate 0.05% ointment and avoidance of mango.(More)
4 cases with differing presentations of contact allergy to acrylates in sculptured acrylic nails are presented. These reactions include nail fold, fingertip and hand dermatitis, face and neck dermatitis, dystrophic nail changes and paraesthesia. We discuss acrylic nails and review the previously published reactions to acrylates in acrylic nails.
570 patients with occupational contact dermatitis (OCD) were seen between 1984 and 1990 at the Skin and Cancer Foundation in Sydney. 336 (59%) were followed up 1 to 5 years later. Roughly 1/3 were healed, 1/3 were improved without complete healing, 1/4 had no change and 1/12 of the patients had deteriorated. The overall improvement rate was in excess of(More)
Patients with intractable eczema are often referred for patch testing to exclude contact dermatitis. If this is excluded, then a diagnosis of endogenous eczema is made. At our clinic, we find a sizeable proportion of these patients do not fit any of the known patterns of endogenous eczema. These patients are given the diagnosis of unclassified endogenous(More)
Benzisothiazolin-3-one is a preservative widely used in industry. The manufacturer states that it is a known skin irritant and sensitiser, but these facts are not well-known. A case is described of contact allergy in a lithoprinter caused by it when used as a preservative in gum arabic. The literature is reviewed and a suitable patch-test concentration is(More)
Five hundred and seventy patients with occupational contact dermatitis (OCD) were seen between 1984 and 1990 at the Skin and Cancer Foundation in Sydney. Data derived from these patients demonstrated that hairdressing, food, construction and the medical industries were the most at risk of OCD. The hairdressing and food industries had a high percentage of(More)
84 patients with oral lichenoid lesions (OLL) were seen in the contact dermatitis clinic. All these patients had reticulate, lacy, plaque-like or erosive lichenoid changes adjacent to amalgam fillings. Patch testing to metallic mercury, 0.1% thimerosal, 1% ammoniated mercury, 0.1% mercuric chloride, and in some cases 0.05% phenylmercuric nitrate and amalgam(More)
Oral lichenoid lesions (OLL) or lichen-planus-like lesions are often idiopathic. Our aim was to determine whether OLL can be caused by allergy to mercury in amalgam fillings, and whether resolution of OLL occurs after replacement of amalgam with other dental fillings. Patients with only OLL (except for 1 case with cutaneous lichen planus) referred for patch(More)
Protein contact dermatitis (PCD) in food handlers is caused by a type I allergy to foods. We report a 17-year-old meat sorter who presented with hand dermatitis. Patch tests with the standard series were negative. Prick testing was positive with lamb liver, ox liver and a mixture of lamb and beef blood. We also summarize seven cases of other food workers(More)
