ABSTRACT

Dermatose ocupacional é qualquer alteração da pele, mucosa e anexos, direta ou indiretamente causada, condicionada, mantida ou agravada por agentes presentes na atividade ocupacional ou no ambiente de trabalho. Os autores referem a importância do tema, a epidemiologia e a etiopatogenia das principais dermatoses ocupacionais: dermatites de contato irritativas e alérgicas, fitodermatites, acnes (elaioconiose e cloracne), ceratoses, cânceres, granulomas de corpo estranho, infecções, oníquias e ulcerações. A clínica da dermatose ocupacional é apresentada em diferentes profissões. Analisam-se os exames laboratoriais pedidos nessas dermatoses, com especial destaque para testes de contato, que são o padrão ouro, e fornecem-se dados do tratamento e prevenção; quanto à prevenção da dermatose ocupacional, informam-se as medidas coletivas e individuais, especialmente, no que respeita ao uso adequado dos equipamentos de proteção individual.


Occupational Dermatosis is described as any alteration in the skin, mucosa or annexes that is directly or indirectly caused, conditioned, maintained or aggravated by agents present in the occupational activity or work environment. The authors of the present study describe the importance of the topic and the epidemiology and etiopathogeny of the main forms of occupational dermatoses: allergic and irritative contact dermatitis, phytodermatitis, acne (elaioconioses and chloracne), keratosis, cancers, foreign body granuloma, infections, onychias, and ulcerations. Clinical findings of occupational dermatosis are presented in relation to various professions. Laboratory tests used to diagnose this condition are analysed, with special emphasis on patch testing, which is the gold standard. Information about the treatment and prevention of this disorder is provided. Collective and individual measures, especially regarding the proper use of individual protection equipment for the prevention of occupational dermatosis, are detailed.

ABSTRACT

General information is summarized, that is necessary to introduce a scientific assessment of the human health and exposure issue concerning dioxin and dioxin-like compound. Scientific literatures were reviewed to assess the background exposures to the dioxin-like compounds for normal residents. Epidemiologic studies were also reviewed to assess malignant and nonmalignant effects of dioxins. In 1997, the International Agency for Research on Cancer classified 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) as a human carcinogen, primarily based on occupational cohort studies. The US Environmental Protection Agency made the same decision in it's Draft Dioxin Reassessment. Epidemiologic evidences point to a generalized excess of all cancers, without any pronounced excess at specific sites. Reported non-cancer effects included a range of conditions affecting most systems. Among them, chloracne, elevation in gamma glutamyl transferase (GGT), and alterations in reproductive hormones are related to TCDD. Other adverse outcomes, such as lipid concentrations, diabetes, circulatory and heart diseases, immunologic disorders, neurobehavioral effects, and developmental outcomes require further study before their respective relationships to TCDD can be more definitively assessed.

ABSTRACT

Chloracne is a refractory acneiform eruption due to halogenated polyaromatic compound(eg. dioxin, dibenzofurans, polychlorinated biphenyls, etc.). 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin, a kind of dioxin isomer, contained in the Agent Orange which was used for defoliating agent during Vietnam war. It is characterized by recalcitrant comedones and cyst predominantly in the malar and postauricular area. Lesions of the penis and scrotum are also relatively frequent. The key pathological feature is the non-inflammatory keratinization of pilosebaceous unit. The meibomian glands are typically affected. Xerosis, conjunctivitis, pigmentation, follicular hyperkeratosis, actinic elastosis are occasionally associated with chloracne. We report a case of typical chloracne due to exposure to defoliating agent during Vietnam war in a 54-year-old-man who shows typical clinical and histopathological features.
