This is a case report on irritant contact dermatitis secondary to calcium oxide exposure during manual cloud seeding operations. A less hazardous substitute such as sodium chloride should be considered wherever possible. Cloud seeding operations are briefly discussed in this report, and the impact of calcium oxide exposure as an occupational hazard is elaborated.

Contact dermatitis of hands is frequent among bakers and, as in other subjects doing ‘wet work’ and/or exposed to powders, is classically irritant in origin (1). This often results in allergic causes being overlooked and, consequently, not investigated adequately, despite the multiple potential allergens in the workplace. We present a case of occupational hand eczema caused by a well-known and ...

Metalworking fluids (MWFs) are a common cause of allergic and irritant contact dermatitis. MWFs being currently used are mostly water based, containing biocides, emulsifiers, and other additives. We performed a retrospective analysis of the etiology of the occupational dermatoses caused by metalworking fluids in three regions of Central Slovakia (population of approximately 2 million) between 2...

BACKGROUND Perfluoropolyethers (PFPEs) are non-reactive perfluorinated (no hydrogen atoms) liquid polymers that showed promise as ingredients of protective preparations in occupational dermatology. OBJECTIVE The aim of this study was to investigate if oil-in-water (o/w) emulsions containing 0.5, 1.0, 2.0 and 4.0% PFPEs (molecular weight 6,250 D) prevent epidermal barrier disruption induced by...

of the hair follicles) and differentiates it from the other conditions.5 Histology of tissue obtained by curettage of a papule is sufficient to establish the definitive diagnosis. Although there are reports of GP that resolved spontaneously once the irritant was eliminated, the lesions usually persist. A number of therapeutic modalities, including topical and oral preparations of retinoids, vit...

Conflicts of interest: The authors have declared no conflicts. hands, legs below knee level, and the area between the shoulder blades (Fig. 1). The patient had no history of dermatological disease and no prior or present exposure to sunlight, infection, or drugs. Biochemical screening was normal, skin cultures were negative, and a biopsy from lesional skin showed changes compatible with dermati...

Perioral dermatitis is a relatively common inflammatory facial skin disorder that predominantly affects women. It is rarely diagnosed in children. A typical perioral dermatitis presentation involves the eruption of papules and pustules that may recur over weeks to months, occasionally with fine scales. The differential diagnosis includes seborrheic dermatitis, systemic lupus erythematosus, acne...
