Dermatitis, contact

Eye and Skin Contact. Some nickel salts and aqueous solutions of these salts, eg, the sulfate and chloride, may cause a primary irritant reaction of the eye and skin. The most common effect of dermal exposure to nickel is allergic contact dermatitis. Nickel dermatitis may occur in sensitized individuals following close and prolonged contact with nickel-containing solutions or metallic objects such as jewelry, particularly pierced earrings. It is estimated that 8—15% of the female human population and 0.2—2% of the male human population is nickel-sensitized (125). 

Amorphous sihca is classified by the Occupational Safety and Health Administration as a nuisance dust. The principal reported health reaction is contact dermatitis resulting from the absorption of protective oils from the skin (1). 

There are hundreds of topical steroid preparations that are available for the treatment of skin diseases. In addition to their aforementioned antiinflammatory effects, topical steroids also exert their effects by vasoconstriction of the capillaries in the superficial dermis and by reduction of cellular mitosis and cell proliferation especially in the basal cell layer of the skin. In addition to the aforementioned systemic side effects, topical steroids can have adverse local effects. Chronic treatment with topical corticosteroids may increase the risk of bacterial and fungal infections. A combination steroid and antibacterial agent can be used to combat this problem. Additional local side effects that can be caused by extended use of topical steroids are epidermal atrophy, acne, glaucoma and cataracts (thus the weakest concentrations should be used in and around the eyes), pigmentation problems, hypertrichosis, allergic contact dermatitis, perioral dermatitis, and granuloma gluteale infantum (251).

Tertiary Amine Catalysts. The Hquid tertiary aHphatic amines used as catalysts in the manufacture of polyurethanes can cause contact dermatitis and severe damage to the eye. Inhalation can produce moderate to severe irritation of the upper respiratory tracts and the lungs. Ventilation, protective clothing, and safety glasses are mandatory when handling these chemicals. 

Caution should be taken when using glutaraldehyde. Gloves and aprons should be worn and adequate ventilation provided. It has been reported to produce contact dermatitis, eye irritation, nausea, headache, rashes, and asthmatic reaction (125).

Allergic contact dermatitis Skin condition that occurs in response to exposure to sensitizing material. It is characterized by redness, swelling and cracking and, sometimes more severe reactions involving the entire immune system. 

The nitrates are available in various forms (eg, sublingual, transmucosal, translingual spray, and inhalation). Some adverse reactions are a result of the metiiod of administration. For example, sublingual nitroglycerin may cause a local burning or tingling in the oral cavity. However, die patient must be aware that an absence of this effect does not indicate a decrease in the drug s potency. Contact dermatitis may occur from use of die transdermal delivery system.

Dermal Effects. Based on a skin patch test, allergic (contact) dermatitis to methyl parathion occurred in a farmer (Lisi et al. 1987).

Dermal Effects. There have been no reports of adverse dermal effects associated with exposure to endosulfan in humans. When tested in farmers, endosulfan did not cause contact dermatitis (Schuman and Dobson 1985). Studies in experimental animals have shown that dermal exposure to endosulfan is only slightly to moderately irritating at relatively high doses (Hoechst 1983b, 1985c, 1985d, 1989b Industria Prodotti Chimici 1975).

Glycolic acid peels are contraindicated in contact dermatitis, pregnancy and in patients with glycolate hypersensitivity. Moreover, they can increase skin sensitivity to ultraviolet light. 

Jessner s Solution has been used for over 100 years as a therapeutic agent to treat hyperkera-totic epidermal lesions [1]. This superficial peeling agent constitutes a mixture of salicylic acid, resorcinol, and lactic acid in 95% ethanol. Jessner s solution causes loss of corneocyte cohesion and induces intercellular and intracellular edema. Jessner s typically induces wounding to the level of the papillary dermis. Historically, resorcinol (a key component of Jessner s peels) was used in concentrations of 10-50% in the early twentieth century. High concentrations of resorcinol were associated with side effects such as allergic contact dermatitis, irritant contact... 

Complications of hydroquinone therapy include acute and chronic reactions. Common acute reactions are irritant and allergic contact dermatitis, and post-inflammatory hyperpigmentation. Lesional and perilesional hypopig-mentation may occur. This is usually a tempo-... 

PIH can be observed after endogenous or exogenous inflammatory conditions. Essentially any disease with cutaneous inflammation can potentially result in PIH in individuals capable of producing melanin. Several skin disorders such as acne, atopic dermatitis, allergic contact dermatitis, incontinenti pigmenti, lichen planus, lupus erythematosus, and morphea have PIH as a predominant feature. Exogenous stimuli,both...
