In Belgian coal mines, some galleries are shored up by metallic beams. Gaps between the rock and the beams are filled in with anhydrite powder mixed with tap water. When the anhydrite "paste" has dried, it becomes very hard by crystallization (1). For many years, occasional complaints of skin irritation have been made by coal miners when anhydrite filling was carried out. The symptoms were itching or burning sensations on the face, neck, forearms, and thighs. No erythema or eczematous reactions…

Gypsum is the dihydrate form of calcium sulfate. The word "gypsum," however, is used to describe different phases of the same material, including anhydrite (calcium sulfate, with no water of
Occupational Contact Dermatitis
In this chapter, occupational information on the working environment that must be obtained for the diagnostic workup is discussed in detail and the prognosis depends on the diagnosis.
Cement-Related Injuries: Review of a Series, the National Burn Repository, and the Prevailing Literature
Cement-related injuries seen in two burn units, literature case reports and series, and the National Burn Repository indicated that this preventable injury occurred primarily in the working age male patient and was associated with long healing times.
Airborne contact dermatitis.
This article considers mainly the second group of airborne dermatitis, which may well have a much higher incidence than has been reported in the literature to date.
Clinical Aspects of Irritant Contact Dermatitis
Therapy and prevention require identification of irritants and reduction of skin contact by gloves or technical measures, and sensitization to environmental allergens does exist and is frequently associated with previous atopic dermatitis.
Contact dermatitis caused by airborne agents. A review and case reports.
A general review is given of airborne-induced contact dermatoses, particularly of the irritant and allergenic types, and differential diagnoses are discussed with regard to contact dermatitis of the face, ears, and neck.
Industrial airborne irritant or allergic contact dermatitis.
The clinical symptoms of both irritant and allergic airborne contact dermatitis are reviewed.
Irritant Contact Dermatitis
The current concept of irritant dermatitis and hyperirritable skin is reviewed and ranges from drying and scaling of the stratum corneum to erythema, edema, whealing, papules, and pustules up to a full eczematous condition virtually indistinguishable from allergic contact dermatitis.
Occupational Airborne Skin Diseases
Most patients consulted in occupational dermatology are referred to as contact dermatitis cases; conceptually, the term “contact dermatitis” implies a direct contact of the skin with the offending
[Airborne contact dermatitis].
The present review deals with the first cases published in 1986, 1991, 2001 by Huygens as well as by Dooms-Goossens, and continues with the other pertaining clinical presentations until to day.

Patch testing with 10% aqueous trona and sodium carbonate was negative, suggesting that the dermatitis was primarily irritant in nature, and a dose-response relationship was observed among underground workers.
Skin irritancy from alkaline solutions assessed by laser Doppler flowmetry
The laser Doppler technique seems to be sensitive enough to detect the erythematous effects of some alkaline solutions and to present the kinetics of the response. The findings also support the view
Assessment of skin irritancy in man by laser Doppler flowmetry
A clear relationship was observed the applied doses of SLS, the recorded blood flow values and the corresponding scores and in a few cases a deviation from the general trend was observed, implying that the naked eye might be unreliable for the assessment of skin irritancy reactions.
