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.

Neuropsychic factors in physical urticaria.

Psychosomatic investigations were made in 18 patients with dermographism, 17 with cold urticaria, and 13 with cholinergic urticaria, and 13 with cholinergic urticaria. The Maudsley Personality Inventory was used and electroencephalograms were recorded from most patients. In the majority of cases of dermographism first symptoms coincided with frustrating situations and psychic stress-intensified manifestations. 81.8% of the patients with dermographism had abnormal electroencephalograms. In cold urticaria the role of psychic factors could not be demonstrated, whereas in cholinergic urticaria 'brief' emotions provoked symptoms in three-quarters of the patients, although no other signs of the role of psychic factors were detected,

Sensitivity to m-phenlenediamine.

Primary contact sensitivty to m-phenylenediamine was noted in 8 of 182 workers handling this substance as hardener. In these patients the period between the beginning of this work and the appearance of dermatitis was shorter if they became simultaneously sensitive to epoxy resin and/or triethylenetetramine. Moreover from among 150 consecutive patients one was positive to m-phenylenediamine and negative to p-phenylenediamine. From among the selected patients positive to p-phenylenediamine more than 40 per cent were also positive to m-phenylenediamine. A large number of the latter patients were as well positive to o-phenylenediamine. No patients were found who would be positive to o-phenylenediamine and negative to m-phenylenediamine. Nearly all those positive to m- and p-phenylenediamine were also positive to the meta isomers of other aromatic amines.

Cross reactions in occupational contact dermatitis. I. Aromatic amines.

Cross reactions are described between particular aromatic amines, between phenylenediamine ortho-, meta- and para-isomers and between aromatic amines and related substances. Moreover, the sensitization pattern and some sources of primary sensitivity to aromatic amines are discussed.
