摘要:

Glutaraldehyde (GTA) is an effective preservative in some consumer products. Because it is a weak cutaneous allergen at certain concentrations, studies were conducted to assess any potential hazard of adding a low level (550 ppm) of GTA to an experimental liquid fabric softener. Allergic contact dermatitis (delayed hypersensitivity) was not elicited in challenge tests of GTA‐sensitive subjects or in repeated insult patch tests of 706 normal human male and female subjects. The subjects were exposed (1) to the experimental formulation, (2) to the formulation with 10 times the normal level of GTA, and (3) to fabrics laundered with the normal use level or with 10 times the normal use level of these expertmental formulation

摘要:

The allergens of lanolin appear to lie in the content of natural free fatty alcohols rather than in the total alcohols as hitherto supposed. The delectable incidence of allergy is increased by the simultaneous presence of detergent. Amongst selected lanolin‐sensitive skin patients, removal of both free fatty alcohols and detergent from lanolin reduces the incidence of detectable hypersensitivity by 96 %. Methods are described for determining free fatty alcohols and detergent in lanolin, and for removing the

摘要:

An outbreak of dermatitis is reported amongst steel erectors, platers and welders working on the relining of a blast furnace. Evidence is produced for regarding this as an occupational primary irritant contact dermatitis.

摘要:

Common fruits and vegetables were tested as such with the “scratch‐chamber” method in 388 patients with various atopic disorders. Of the patients with hypersensitivity to birch pollen, 36% showed immediate positive responses to these natural, fresh materials. Apple, carrot, parsnip and potato elicited reactions more often than, e.g. swede, tomato, onion and parsley. On the basis of clinical data, the relevancy of the results of the skin tests was 80–90%. Both “false positive” and “false negative” responses were seen.Itching and tingling with or without oedema of the lips, mouth and tongue were the most common complaints after eating raw fruits and vegetables. In addition, laryngeal and abdominal disturbances, rhinitis and hand dermatitis were recorded.Among patients without allergy to birch pollen, reactions to fruits and vegetables were rare.The nature of the allergens could no

摘要:

A case of acquired photocontact allergy to furocumarins in plants is reported. Photopatch testing was performed with four psoralens [8‐melhoxypsoralen (8‐MOP), 5‐methoxypsoralens (5‐MOP), trimethylpsoralen (TMP) and imperatorin (IMP)]. The use of serial dilutions of the test compounds made it possible to differentiate between photoallergic and phototoxic reactions. 8‐MOP gave a positive eczematous text reaction down to a concentration of 0.0001% The reactions to 5‐MOP and IMP also were positive, while that to TMP was negative. Histopathological examination of a biopsy specimen from a positive test site showed changes consistent with photoallergic contact dermatitis.The multiple reactions could be explained on the basis of multiple sensitization, but cross reactions cannot b

摘要:

The Persian cloth shoe (Maleki) which has been in use for more than 800 years has a strong cloth sole and a woven cotton upper. In the last 20 years, used cur tyres have became readily available in Iran and the soles of some shoes are now made from these. A man with the typical picture of rubber dermatitis on the soles of his feet is described. On pinch testing he gave a 2+ positive to PPD rubber and this was thought to be due to the fact that he had wornMalekishoes for several years.

摘要:

United states federal regulations require ingredient listing on cosmetics labeled after November 30, 1976. Standardized ingredient nomenclature from a reference text will be utilized to minimize confusion which might arise if various synonyms for chemical names were used.This new information on cosmetics labeling will assist physicians in the diagnosis of cosmetic‐related dermatoses. It should facilitate the patch testing procedure by enabling the dermatologist to focus attention on suspect ingredients early in the evaluation. Once the identify of offending ingredients in a cosmetic has been determined for a particular patient, the individual will have the opportunity to avoid those ingredients and related ingredients in future purchases of cosmetic
