摘要:

Contact urticaria was observed in a kindergarten in 18 of 20 children following the intake and accidental perioral application of a mayonnaise salad cream. In healthy adult controls, stinging tests and closed 20 minute patch test with the salad dressing were positive in 9 out of 12 and 4 out of 10 cases respectively. Twenty minute patch tests with the different components of the salad dressing were positive only so sorbic acid (SA) and benzoic acid (BA). Urticaria was provoked by inunction of the salad dressing periorally in two healthy boys. Serial 20 minute closed patch testing with varying concentrations of SA in 91 patients and BA in 41 patients gave almost identical results: positive reactions in two thirds of the patients with the highest concentrations. The response was only partially blocked by anti‐histamine applied locally before testing. Non‐immunologic mechanisms are probably responsible for the transient reaction, and no restriction in the extensive use of SA or BA as preservatives in food should be conside

摘要:

63 female patients with nickel allergy and hand eczema were reinvestigated 6 years after the primary investigation. 30% of the patients were healed. Patients with the pompholyx‐type eczema had the worst prognosis. The start of hand eczema was not correlated to any particular occupation. There was a strong correlation between a history of metal sensitivity and a positive patch test reaction. High frequencies of personal and family atopy were found, and atopy made the prognosis worse. Determination of serum IgE was not found to be of any use in predicting the prognosis in patients with nickel allergy and hand eczem

摘要:

The sensitizing capacities of helenin (an extract from aCompositae Inula heleniumL.), alantolactone and isoalantolactone (two isomeric sesquiterpene lactones), were assessed by sensitizing guinea pigs of different strains: albino Himalayan spotted, Pirbright and Hartley. Both alantolactone and isoalantolactone are found to be sensitizers if injected intradermally. Only Pirbright guinea pigs showed a high sensitization rate by the open epicutaneous technique; with this method, alantolactone was the more potent sertsitizer.

摘要:

A transient facial rash in six healthy female operators of visual display units is described. The cause has not been established, but circumstantial evidence strongly favours a link between the rash and the working conditions. A study performed to establish the aetiology is described.

摘要:

A patient experienced repeated episodes of facial dermatitis with subsequent development of facial hyperpigmentation. A positive patch test to potassium dichromate strongly implicated chromium hydroxide, used as a pigment in a commercial toilet soap, as a contact allergen. Pigmented cosmetic dermatitis may result from repeated episodes of facial inflammation, due to contact allergy from cosmetics.

摘要:

Twenty blood donors developed a dermatitis at the site of venesection within a few hours of giving blood. A local anaesthetic administered with a Dermo‐Jet had been used before extracting blood. In only 2 cases was sensitivity to the local anaesthetic found. In the others the reaction was caused by nickel released from the Dermo‐Jet. The quantity of nickel released is greater from the anaesthetic solution than from deionised water. It increases with the time that the anaesthetic remains in the Dermo‐Jet. The release of nickel is greater from a used Dermo‐Jet than from a new one. Histology revealed a lymphohistiocytic infiltrate at the level of the deep

摘要:

28 patients reacting to a PVC adhesive tape used in routine patch testing gave positive reactions to diphenylthiourea (DPTU) and to phenylisothiocyanate (PITC) in low concentrations. DPTU is a heat stabilizer in the PVC and is partly decomposed to PITC. The two substances were also found in another type of PVC. Thioureas giving isothiocyanates are also used in certain types of rubber. Isothiocyanates are present in plants, mainly of iheCruciferaefamily, and are also formed from thiuram sulfides and thiocarbamates. The connection between isothiocyanates derived from different sources should be investigated.

摘要:

Dogger bank itch is the popular name of an allergic contact dermatitis caused by sensitization to an allergen from the marine bryozoanAlcyonidium gelatinosum(L.). The dermatitis is a type‐4 allergic reaction and the hapten responsible has been isolated, purified, structure elucidated, and synthezised. A critical review of the literature is presented and possible future research, based on experiments with the pure allergen, is discusse

摘要:

256 patients with a clinical diagnosis of contact dermatitis were patch tested with European standard series allergens in a period from 1976 to 1979. Significant positive reactions were observed with all allergens, among which were paraphenylenediamine (7.8%), wood tars (7.8%), formaldehyde (7.0%), balasam of Peru (6.6%), neomycin (5.1%), ethylene‐diamine (0.8%), naphthyl‐mix (0.8%), mercapto‐mix and PPD‐mix (1.2%).North American Standard Series allergens were also patch tested in another 178 patients in the years 1976, 1977, 1979 and 1980. Similar results were obtained with allergens common to both series and, of the others, ammoniated mercury (12.9%), thimerosal (9.5%), captan (5.6%), and hydroxycitronellal and Caine mix (4.5% each) were p

摘要:

A case of contact sensitivity to ethylenediamine dihydrochloride is reported. The clinical and histological features were in keeping with early mycosis fungoides. The eruption cleared with avoidance of the allergen. Continued contact with the allergen was traced to its retention in a trouser pocket lining. The term “lymphomatoid contact dermatitis” should be confined to cases where the lymphomatoid features are due to a positively reacting aller
