Contact dermatitis toxicL24.-

Exogenously triggered, acute or chronic inflammation of the skin which, in contrast to allergic (contact allergic) contact dermatitis, is not triggered by prior sensitization and is generally strictly limited to the site of exposure. In the case of chronic hand dermatitis and patients who are predisposed to it, an occupational disease must be clarified.

"Dermatitis " after acute or chronic toxic effects (according to Rueff F and Schnuch A 2018) - See also under eczema term

• Chronic (toxic) hand dermatitis
• Pityriasis simplex
• Exsiccation eczematide
• Intertrigo
• Diaper dermatitis
• Stoma eczema(ostomy dermatitis)
• Airborne contact dermatitis
• Plant dermatitis (e.g. meadow grass dermatitis)
• Paederus dermatitis
• Caterpillar dermatitis
• Eczema caused by wool and other textiles
• Dermatitis papulosa juvenilis (juvenile plantar dermatosis)
• Eyelid dermatitis
• Lip lick eczema (lip lick dermatitis)
• Perianal eczema (perinal dermatitis)
• Patch dermatitis

In most cases the hands are affected (90%); less frequently the feet or other covered parts of the body.

Erythema strictly limited to the site of exposure (back of the hand, interdigital spaces, rarely palms), two-dimensional, scaly and itchy erythema, grouped nodules and plaques, depending on the acuity also vesicles or blisters. In addition, erosions, crusts and scratching effects.

Avoidance or reduction of the acting contact noxae. Depending on the degree of severity and acuteity, purely external or internal therapy.

Phase-appropriate therapy of dermatitis, see below. Eczema.

Initially, medium to strong glucocorticoids, in aqueous base, solution or hydrophilic cream, such as 0.1% hydrocortisone butyrate (e.g., Laticort cream) or 0.1% triamcinolone acetonide (e.g., Triamgalen, altetnative: Rp:triamcinolone acetonide cream hydrophilic 0.025/0.05/0.1% (NRF 11.38.) . In the weeping or chronic eczema stage, medium to strong glucocorticoids in greasy bases such as Laticort ointment, 0.25% prednicarbate (e.g. ^Dermatop® cream/ointment), 0.1% mometasone furoate (e.g. ^Ecural® cream/ointment). In addition, moist compresses with NaCl solution, especially in the case of weeping skin lesions, with antiseptic additives such as quinolinol (e.g., Chinosol 1:1000), or potassium permanganate (light pink) if there is evidence of superinfection. In the vesicular stage, fat-moist treatment with topical glucocorticoids in a high-fat ointment base (e.g., hydrocortisone 1% in Vasel. alb. (Hydrocortisone ointment 1%) and moist compresses, cotton glove if necessary.

In severely scaling-hyperkeratotic forms, the application of topical glucocorticoids is also recommended under occlusion.

Omit soaps and detergents, cleanse with oil-containing baths (Balneum Hermal, Balmandol, Linola fat oil bath). Try antiphlogistic externals such as ichthyol (e.g. Ichthosin cream). Follow-up treatment with refatting externals in a compatible base (Alfason repair, Excipial repair sensitiv, Linola Fett, Vaseline alb., Excipial® almond oil ointment) if necessary addition of 2-10% urea (Rp: urea cream hydrophilic 5 or 10% (NRF 11.71.) .

If necessary, apply Zarzenda cream (internationally known as Atopiclair®⁾. This is a steroid-free, topical multicomponent cream with a strong antipruritic, anti-inflammatory effect (apply 2 times/day).

In case of occupational conditions: skin protection preparations, gloves, etc., if necessary. See below Occupational dermatoses.
