1/7. Contact dermatitis due to printer's ink in a milk industry employee: case report and review of the allergen paraphenylenediamine.Paraphenylenediamine is a common cause of occupational dermatoses in hairdressers, metallurgy workers, and others. hand dermatitis developed in an employee of a milk packaging facility. The employee's hands were exposed to milk cartons embossed with wet printer's ink on a daily basis for 2 years. The worker was evaluated through a history, physical examination, and patch testing with 50 standard allergens. Patch testing revealed a positive reaction to paraphenylenediamine. The hand dermatitis resolved once the patient instituted protective measures. The worker's reaction might represent a delayed-type hypersensitivity reaction to printer's ink that contained this agent. More likely, the inciting agent was some other ingredient of the printer's ink that cross-reacts with paraphenylenediamine.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/7. Long-standing dermatological manifestations in a patient with chronic heavy metal intoxication.A patient with chronic metal intoxication is described, presenting during four years after the cessation of her exposure to industrial substances, maculo-papular eruptions with several ulcerated lesions and excoriations on her abdomen and buttocks. She also had pallor of her face, greyish-dark discoloration of the hair, while the fingernails were brittle and sensitive. Scrupulous physical examination excluded further cutaneous involvement. The immunological workup revealed both phenotypic and functional defects in cellular immunity.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/7. dermatitis artefacta?A 35-year-old man presented with a 2-month history of intensely pruritic excoriated and crusted linear lesions on the dorsa of the left hand and left forearm (Fig 1). The patient had worked in construction for 2 years, and his job consisted mainly in covering the facades of buildings with cement. The patient was right-handed and used a black rubber glove as a protective measure only on his left hand (Fig 2). He reported that the lesions resolved partially during holidays and weekends and clearly flared in association with his work. There was no history of atopic dermatitis, drug use, or intolerance to metals, rubber, or fruits. On physical examination, linear excoriations with crusts were observed on the dorsa of the left hand, extending to the ventral and dorsal aspects of the forearm, involving the whole area that was in contact with the glove. Lichenified erythematous plaques and excoriations on the dorsal surface of the metacarpophalangeal joints and scaly lesions on the dorsal surfaces of the fingers were also present. On the palm, only discrete hyperkeratosis was seen. The right hand and forearm were free of lesions. He complained of intense pruritus when wearing the rubber glove and admitted to continuous scratching to relieve his discomfort, inducing the linear and excoriated lesions. Treatment with topical corticosteroids was initiated, with progressive resolution of the lesions.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
4/7. An outbreak of rat mite dermatitis in an animal research facility.We describe an outbreak of rat mite dermatitis that affected 15 employees of an animal research facility. Cases of rat mite dermatitis are infrequently reported, and outbreaks are reported even less. Our case series demonstrates that in contrast to most prior outbreaks, rat mite dermatitis may occur even in modern, well-maintained physical surroundings and thus remains a relevant diagnosis today.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/7. Occupationally induced psoriasis.psoriasis of the hands may be triggered by work, especially in occupations involving physical trauma or contact with irritants. When limited to the hands and in absence of other typical lesions, diagnosis can be difficult particularly when coexisting with contact eczema. It is necessary to establish diagnostic criteria which help to establish a relationship between clinical manifestations and noxious stimuli at work. Prevention should be directed to early identification of cases and adequate preemployment physical examinations in order to avoid permanent disability.- - - - - - - - - - ranking = 2keywords = physical (Clic here for more details about this article) |
6/7. Prevention of occupational skin disease through use of chemical protective gloves.Selection of chemical protective gloves for use against industrial liquids in the controlled workplace is accomplished by risk analysis, in which the appropriate physical and chemical glove properties needed by the worker to perform the job are determined. Candidate protective gloves are then subjected to chemical permeation testing. Three representative case studies illustrate risk analysis and glove selection.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
7/7. Occupational allergic contact dermatitis from cyanoacrylate.cyanoacrylates are widely used in adhesive techniques. Cyanoacrylate adhesives differ physically for the different needs of application, and chemically in function of the size of ester molecules. A 40-year-old man employed at the National Mint and Stamp factory presented with hyperkeratotic lesions on the fingers of the right hand. His job consisted of fixing microchips to plastic phone cards with Loctite Series 414. Patch testing confirmed sensitivity to cyanoacrylates. After the diagnosis of allergic contact dermatitis was established, the patient, to be cured of the dermatitis, changed his workplace 2 months later.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
