Atopic dermatitis: triggering factors.
Atopic dermatitis is a hereditary disorder, frequently associated with allergic rhinitis and bronchial asthma. The disease may be influenced by many triggering factors such as irritants, aeroallergens, food, microbial organisms, sex hormones, stress factors, sweating, and climatologic factors. Moreover, it is important to be aware of contact allergy as a complicating factor. This review deals with recent clinical, experimental, and some therapeutic data on these triggering factors.

Acanthosis nigricans caused by nicotinic acid: case report and review of the literature.
Drug-induced acanthosis nigricans has been reported in the literature. We present a patient with familial combined hyperlipidemia who developed nicotinic-acid-induced acanthosis nigricans. The literature on the cutaneous side effects of nicotinic acid as well as on the medications that can cause acanthosis nigricans is reviewed. Some hypotheses on the pathogenesis of nicotinic-acid-induced acanthosis are presented.

alpha-Amylase, a flour additive: an important cause of protein contact dermatitis in bakers.
BACKGROUND: alpha-Amylase, an enzyme commonly used in flour additives, has been reported to be an important cause of rhinitis and asthma in bakers. OBJECTIVE: Our purpose was to determine whether this enzyme could also cause dermatitis. We tested it routinely in bakers with hand eczema. METHODS: Patch tests were administered with the International Contact Dermatitis Research Group standard series and a bakery series and scratch-chamber or prick tests were performed with the bakers' own material and with alpha-amylase powder. RESULTS: Of 32 bakers tested, seven had an immediate wheal-and-flare reaction and two also had a delayed eczematous reaction. High dilutions of the alpha-amylase powder still gave strong reactions. CONCLUSION: alpha-Amylase is an important cause of skin reactions in bakers and should be tested routinely if a contact allergy is suspected.

[Comment on the contribution by L. Weber: Yersinia exanthema].
Lutz Weber has described Yersinia exanthema, a distinctive dermatological disorder characterized by three or all of the following signs: 1. A typical erythema-multiforme-like eruption, particularly on the neck, shoulders, and arms, 2. Erythema nodosum, 3. Conjunctivitis, particularly on the nasal side of the conjunctiva, 4. Arthralgia. The case presented here concerns a patient who satisfied all of the criteria for Yersinia exanthema and in whom no infection could be demonstrated.

Contact allergy to isothiazolinone derivatives: unusual clinical presentations.
Contact allergic reactions to the mixture of 5-chloro-2-methyl-4-isothiazoline-3-one and 2-methyl-4-isothiazoline-3-one are most frequently associated with intolerance to cosmetics. The present article points out that such reactions, particularly on the face, can have unusual clinical presentations that are very similar to seborrheic eczema, lupus erythematosus, lymphocytic infiltrate or photodermatitis. Atopic dermatitis is also often erroneously suspected.
