摘要:

Anaerobic sealants are acrylates that pulymerize in the absence of oxygen. They are used principally in the engineering and electronic industries. Their use can cause occupational dermatitis in the workers who handle them. In this work, we report our experience with 6 patients who presented with allergic contact dermatitis to these sealants.

摘要:

Contact sensitivity to 4 polyamines present in technical grade triethylenetetramine was investigated using the ‘VAA mouse’ assay and the guinea pig maximization lest (GPMT). The criteria used 10 assess sensitivity in the GPMT classed all substances as having the same degree of sensitising potential The mouse assay ranked N‐(2‐piperzin‐l ylethyl)ethylenediamine as having a significantly greater sensitising potential than the other

摘要:

Assessment of erythema in experimentally‐induced irritant contact dermatitis has been performed visually and using the laser Doppler flowmeter (LDF). A close correlation was shown between the 2 methods (r= 0.9079,p<0.001), with the LDF producing menu blood flow values which were able to discriminate between the different visual scores. Of the 100 patch tests evaluated, 3 gave poor correlations between their visual and LDF readings, including 2 dithranol reactions and 1 sodium hydroxide response. Patch tests with no visible erythema had blood flow values similar to those of normal untreated skin. Although the LDH was an easy instrument to operate, it was not considered suitable for use in the routine patch lest clinic, due mainly to the unacceptable length of time required to measure each patch tes

摘要:

We report 3 patients with persistent symptoms at vaccination sites. All were allergic to aluminium and one to thiomersal and neomycin too. Aluminium allergy causes false positive patch test reactions and we propose methods of patch testing patients with symptoms at vaccination sites in order to avoid this problem. The practical relevance of allergy to non‐toxoid constituents of vaccines is discusse

摘要:

A standard patch test series was tested for 7 years (1977–1983) in a total of 11,962 patients. The annual frequency of positive reactions to the compounds tested was assessed for the total and for males and females separately. During the observation period, there were significant increases in positive reactions in the total group from 6.2% to 12.7% for nickel sulphate. from 5,3% lo 7.0% fur balsam of Peru and from 3.8% to 6.5% for potassium dichromate, reflecting significant changes in both sexes. The frequency of positive reactions to wool alcohols, formaldehyde, neomycin sulphate, paraben mix and gentamycin sulphate significantly increased, while that of positive reactions to clioquinol, mercuric chloride arid turpentine peroxide significantly decreased in cither males or females, sometimes leading to significantly changes in the total grou

摘要:

2 patients with leg ulcers got worst after the application of a compound mixture of sugar and povidone‐iodine (sugar/PI compound), Because they had been suffering from stasis dermatitis, symptoms of contact dermatitis were ambiguous. Patch tests showed positive reactions to 10% povidone‐iodine in water and 5% potassium iodide in water, with no response to sugar. They were also tested with sugar/PI compound, containing 3% povidone‐iodine, resulting in another positive reaction. They improved after the application of sugar/PI compound was discontinued. Contact dermatitis from topical agents should be considered as more probable than angry back syndrome in cases of leg

摘要:

The patch test reactivity to different petrolatum preparations and concentrations of colophony (gum rosin) was compared. A serial dilution lest with gum rosin 20%‐0.001% gave a clear dose‐response relationship with a maximum response 10% and 20%. Patch testing with 60% in the routine lest did not reveal any further cases compared to simultaneous testing with 20%. Irritancy to the 60% concentration was seen in some cases. A good correlation in reactivity was found between commercially‐supplied lest preparations for routine testing and homogeneous preparations made up in our laboratory. Our results imply that a concentration of 10% is well worth considering fur routine te

摘要:

Black rubber chemicals are capable of causing an allergic contact dermatitis, in some cases associated with a purpuric capillaritis. A typical case or such a purpuric reaction is described in a man sensitive lo black rubber chemicals.
