Contact sensitivity to phenylglycidyl ether.

From among 40 workers with dermatitis who did not have contact with phenylglycidyl ether but worked with epoxy resins, 5 were positive to Epidian 5 and phenylglycidyl ether. Cross reactions between these contactants were noted in 3 of the 17 guinea pigs with primary sensitization to epoxy resin or the tested diluent. For 58 persons coming into contact with phenylglycidyl ether the frequency of sensitization to the contactant was determined and the mean period between starting work and the occurrence of dermatitis was calculated.

Occupational dermatitis among health service workers.

Health service workers in the number of 152 suffering of dermatitis were examined. They included 43 physicians, 25 stomatologists, 59 nurses, 14 hospital-wards and 12 other persons working in hospitals, clinics and pharmacies. In physicians occupational contact dermatitis occured in ten patients, exclusively among those performing operations, most frequently surgeons and ginecologists. Rubber gloves (5 patients) disinfectants and chromic catgut were the sensitizing objects. Moreover, a woman gynecologist positive to nickel observed that also the use of a speculum exacerbated her lesions. A laryngologist with seborrhoic dermatitis, strongly positive to formaldehyde, had exacerbations when using--during surgery--a microscope disinfected with formalin solution. Allergic occupational contact dermatitis was diagnosed in 12 stomatologists; they were positive to eugenol, mercury, novocaine or formaldehyde. Among 24 nurses with allergic occupational contact dermatitis, those positive to antibiotics (specially to semisynthetic penicillins) or to disinfectants (most of them to formaldehyde) were most numerous. Some nurses were sensitive to such drugs as Propranolol, Aminophyllinum or chlorpromazine hydrochloride. To the latter drug also a ward attendant was positive.

New contact allergens and allergen sources.

In the report new contact allergens and allergen sources detected in Warsaw in the period 1975-1977 are described. They are divided into 3 groups: industrial allergens, remaining occupational allergens and cosmetics. There are given some data concerning the substances present in industrial oils, hardeners and epoxy resin solvents, drugs sensitizing nurses, several new sources of chromium allergens, essential oils and synthetic flavours. Results obtained with various star anise oil samples are described. Essential oils and synthetic flavours. Results obtained with various star anise oil samples are described. Essential oils and synthetic flavours are discussed as the main allergens in cosmetics.

Contact sensitivity to trivalent chromium compounds.

The investigations confirmed the known fact that for skin tests larger amounts of trivalent chromium compounds are necessary than those of potassium dichromate. It was also observed that some patients react to relatively higher Cr VI and lower Cr III concentrations and others vice versa. Chromium nitrate and chloride release and that of potassium dichromate was determined and converted to the chromium content in the concentrations used for skin tests. It was found that Cr III compounds cannot be used for skin tests in a 0,5% concentration if only because they are released in undeterminable amounts. Release of Cr III and potassium dichromate from bases containing the same amount of substance when converted to chromium demonstrated that the different release of Cr III is not an additional cause of the fact that much higher concentrations of Cr III compounds have to be used for patch tests than those of Cr VI compounds.

Sensitivity to 2-chlorocyclohexanone and its derivatives.

Three workers developed dermatitis when synthesizing lysine from cyclohexanone; they showed positive patch tests to 2-chlorocyclohexanone and some of its derivatives. Two of them became sensitive to at least two differen compounds.

Balsam of Peru as screening agent for essential oils sensitivity.

The standard series and 35 essential oils were tested on 450 patients with dermatitis. It was found that those simultaneously sensitive to essential oils are more frequently negative than positive to balsam of Peru. The remaining 3 balsams, however (colophony, turpentine and wood tars), are also screening agents for essential oils. All four balsams reveal sensitivity to essential oils in most of the subjects tested. In patients negative to all 4 balsams of the standard series, attempts to find an essential oil with which tests would be simultaneously frequently positive with those for other essential oils failed.
