    Notes: Skin prick tests (SPT) with freeze-dried spices and 5% (w/v) spice extracts were performed on 50 patients with 2 + or stronger SPT reactions to spices per se, and RAST were performed on 10 of them. Freeze-dried extracts produced mostly equal or stronger SPT reactions than corresponding whole spices, but 5 % (w/v) extracts produced weaker reactions and also remained totally negative in some patients. Positive RAST results were seen in all 10 patients tested. The correlation between the RAST and SPT results was good for mustard and paprika, but poor for cayenne, coriander, caraway and white pepper. Five patients with positive SPT and RAST for spices contracted rhinitis from powdered spices in their working environments, and one patient suffered from gastrointestinal pains caused by spiced food. The others had noticed no clinical symptoms caused by spices. The present results thus indicate that both SPT and RAST should include purified spice extracts.

    Notes: Background: Glucocorticosteroids form the basis of therapy for asthma and other allergic diseases. However, they frequently cause delayed contact allergy and occasionally immediate allergy. The purpose of this study was to investigate the occurrence of corticosteroid allergy among patients with asthma and with some complaints caused by inhaled corticosteroids.Methods: Patch tests with corticosteroids were performed in 51 asthma patients with side-effects from inhalant corticosteroids and in 50 symptom-free asthma patients using the Finn Chamber® system. The corticosteroids and their vehicles were: betamethasone-17-valerate 1% in petrolatum, hydrocortisone-17-butyrate (Hc-17-B) 1% in ethanol, tixocortol-21-pivalate 1% in petrolatum, budesonide 0.1% in petrolatum, beclomethasone dipropionate 0.1 and 0.5% in petrolatum and as inhalant powder 200 μg, and fluticasone propionate 0.1 and 0.5% in petrolatum and as inhalant powder 250 μg. The results were read twice, on D4–5 and again on D10.Results: Two patients in the symptomatic group reacted to corticosteroids in patch tests, one to betamethasone-17-valerate, Hc-17-B and budesonide, and the other to budesonide and Hc-17-B. The first patient suffered from widespread eczematous dermatitis when using beclomethasone. Fluticasone caused oropharyngeal irritation, hoarseness and shortness of breath. The second patient experienced a severe rash after the fourth budesonide inhalation. She had used various topical corticosteroids for her atopic dermatitis without any side-effects. None of the symptom-free patients showed positive results.Conclusions: Delayed allergy to corticosteroids occurs occasionally in asthma, perhaps in the same frequency as in dermatitis. A positive patch test reaction usually means clinical allergy, i.e. the patient cannot use that particular steroid. Cross allergy between corticosteroids is common. However, such patients usually tolerate some other common corticosteroids.

    Notes: Reindeer herding is a major source of living for more than 4200 inhabitants in northern Finland. To determine the prevalence of allergic symptoms among reindeer herders clinical examinations and skin prick tests (SPT) with nine inhalant allergens were performed in 211 randomly selected men from 21 to 69 (mean 45) years. Specific IgE antibodies to reindeer epithelium (RE) and total serum IgE were evaluated in 99 herders, five persons who handled reindeer leather indoors, 21 atopic patients with cow allergy and another 20 subjects with specific IgE to other inhalant allergens. Positive SPT to RE was detected in one and specific IgE by using enzyme allergosorbent test (EAST) (≥ 0.8 PRU/ml) in seven herders. Specific IgE to RE was also demonstrated in one control. Using RAST inhibition a patient with cow allergy did not show cross-reactivity between cow and RE while another patient did. Thus, RE should be included in the allergy test panel when hypersensitivity to RE is suspected.

    Notes: Only seldom have food additives been shown to cause true allergic (immunological) reactions. Adverse effects due to various pharmacological or other mechanisms are much more common. The individual tolerance may be decreased for one reason or another, and may fluctuate from time to time. Many patients suffering from food additive reactions have atopic constitutions and such clinical symptoms as flexural dermatitis, rhinitis and asthma. The most important skin symptoms caused by food additives are urticaria, angioneurotic edema, and contact urticaria. Azo dyes, benzoic acid and several other common food additives may aggravate or, more rarely, even cause urticaria. Spices are one of the most common causes of immunological contact urticaria. Non-immunological contact urticaria is produced by numerous spices, benzoic acid, sorbic acid, cinnamic acid, and many essential oils. Asthma and rhinitis are the main hypersensitivity symptoms in the respiratory tract, and azo dyes, benzoic acid, and sulfitic food additives are the most common causative agents. Systemic and respiratory reactions to food colorants and benzoates have been claimed to occur more frequently in acetylsalicylic acid- (ASA-)sensitive patients than in non-reactors. Hypersensitivity reactions in organs other than the skin and respiratory tract are rare or poorly documented. Psychological factors play an essential role in both food and food additive reactions.

    Notes: Worldwide, there are 3 major standard series of patch tests, the European, North American and Japanese, together presenting 32 allergens, the differences between them being the result of regional variation in allergen distribution as well as differences in dermatological opinion. We propose a “minimal” international standard series of 20 allergens, together with an “extended” international standard series of 14 allergens.

    Notes: The proliferation rate, collagen metabolism and collagen and elastin messenger-RNA levels were studied in fibroblasts derived from patients who had received many courses of either systemic 8-methoxypsoralen or topical trioxsalen PUVA treatment. The proliferation rate of fibroblasts as measured by the incorporation of 3H-thymidine or by cellular division was decreased in those obtained from patients who had PUVA treatment as compared with controls. Collagen synthesis was slightly increased in the cells from PUVA-treated patients, but the relative collagen synthesis and the ratio between types I and III collagen were unchanged. The levels of collagen and elastin mRNAs were increased in fibroblasts derived from the PUVA-treated patients. No significant differences in histology or immunochemistry could be found in the biopsies taken from topical and systemic PUVA-treated patients.

    Notes: The frequency and immunological background of dermatitis occurring in lichen pickers during the 3– to 4–month picking season were studied in a small community in northern Finland. Thirty of 164 lichen pickers had suffered from dermatitis at least on the fingers and the dorsa of their hands, and many of them also had dermatitis on their forearms, faces, etc. Fifteen of them were subjected to epicutaneous and photo-cpicutaneous testing with crushed Cladonia alpestris (L.) Rab. and some fractions of it. Allergic contact reactions were seen in nine subjects, three of whom also had positive photo-epicutaneous test reactions from lichen allergens. No immediate reactions were seen in scratch or scratch chamber tests with crushed Cl, alpestris or with its alcoholic extract.

    Notes: Epicutaneous tests with O.1 % merthiolate in petrolatum showed hypersensivity in 96 of 4647 eczema patients (2.0%) and ill seven of 105 health recruits (7%). There was a marked preponderance of young age classes in the eczema group. Twelve of 41 merthiolate-positive patients tested reacted to mercury alone, three to thiosalylic acid alone and one to both. The remaining 25 patients; reacted to neither of the individual components although the merthiolate complex as a whole gave a positive test result. Forty-five of the merthiolate-positive patients were tested subcutaneously with 0.5 ml of a 0.01% merthiolate solution, i.e. a dose equal to that contained in one shot of tetanus toxoid, fur example. Nine patients developed a local reaction at the site of the injection, and the area became eczematous in four cases. In one of the patients the eczema spread over the body, causing fever. Since merthiolate-sensitive patients also react to merthiolate administered intracutaneously. the vaccinator should avoid the use of needle whose outer surface tins been contaminated when the vaccine was aspirated from the bottle. However, even when this precautionary measure is taken, local reactions can be expected in such a high percentage of merthiolate-sensitive persons that merthiolate in vaccines should be replaced by another antibacterial agent.

    Notes: A peroral challenge lest with 2–15 ml of propylene glycol (PG) was made in 38 patients with allergic-type epicutaneous test reactions to PG. Eight of 10 patients with a positive epicutaneous reaction to 2% PG and seven of the other 28 patients with a positive epicutaneous reaction to 10–100 % PG developed an exanthem 3–16 h after ingestion of the drug. In all hut one case the rash disappeared within 24–48 h without any medication. In one ease the exanthem was treated with prednisone for 4 days, and the symptoms disappeared gradually in 6 days.None of the 20 control patients had skin symptoms, Nausea, vertigo and a curious sensation were recorded in four PG-sensitive patients and in three control patients. These symptoms were apparently due to the general pharmacodynamic effects of PG and they were regarded as non-allergic in nature.It was concluded that PG is a potential allergen and it must he added to the list of causes of drug exuathems

    Notes: In all, 896 Finnish farmers (305 men and 587 women), representing 77% of those reporting hand or forearm dermatosis in a questionnaire survey in 1979, were asked again about their dermatosis and current work in 1991. More than 50% of the study population had left farming since 1979. In 1991, 26% of men and 21% of women had a current dermatosis on the hands or forearms, and altogether, 44% of men and 39% of women reported a hand dermatosis within the past 12 months. Significant determinants of persistent hand dermatosis, in a logistic regression model, were continuation of farm work, history of skin atopy, symptoms of metal allergy, and age under 45 years. Handling cattle, e.g., milking, was considered an exacerbating factor of the dermatosis by 37% of those who had milked sometimes in their lives. In this group, 75% of hand dermatoses in those who had finished milking work had healed. The results indicate that giving up or changing work improves the prognosis of hand dermatosis in farming.
