Disease prevention skin protection

Green tea and its constituents have been shown to protect skin from irritation caused by radiation as well as chemicals. EGCG has been shown to prevent skin damage caused by UVA radiation and 12-0-tetradecanoylphorbol-13-acetate (TPA) application through inhibition of NF-kB DNA binding and expression of MAP kinase and Cox-2 Psoriasis is an inflammatory skin disease in which there is hyperproliferation and improper differentiation of epidermal keratinocytes. Green tea polyphenols have been shown to alleviate symptoms of psoriasis in mice. ... 

Numerous researchers have drawn attention to the beneficial properties that avocado could provide to human health. Some of these healthy benehts have been summarized in Figure 8.1. Wilson Grant, in 1960, published the hrst clinical study where avocado intake was associated with the maintenance of normal serum cholesterol levels, or even with their reduction [7]. Later on, in the 90s and beginning of 2000 there was an increase in the number of works that studied the relationship between avocado fat and its effect on cardiovascular diseases, cholesterol, lipid profile, weight control, and diabetes [8-16]. While the principal healthy benehts attributed to avocado fruit are the aforementioned, some others have also been evaluated, such as prevention and treatment of osteoarthritis [17,18], anticancer properties [19-24], protective activity against liver injury [25], skin protection [26-28], reduction of risk of macular degeneration [29], inhuence on short-term memory [30], antioxidant activity [31-37], reduction of metabolic syndrome risk [38,39], and anti-inhammatory effects [31,32,40]. 

A distinction is usually made between primary prevention, i.e. inhibition of the induction and onset of a disease, and secondary prevention, i.e. inhibition of relapses. Tertiary prevention aims at inhibition of worsening ( quality of life ). The value of disease prevention is evident to individuals, the community and the medical profession. For human, social, and economic reasons, it would be of great benefit if people exposed to harmful chemicals and products, physical factors, and biological agents could be protected from developing occupational skin diseases. 

Workplace visits include a presentation on types of occupational skin damage and ways of protection. They are particularly effective because they include not only the diseased person but also other workers, who are probably not affected, and the employer. Thus, prevention is addressed not only in the context of individual behavior but also in the context of (occupational) setting. During such a visit, the cost and benefit of skin protective measures can be discussed. 

The use of personal protective measures, such as topical insect repellents, has been essential in the prevention of arthropod transmitted disease. However, skin irritation is a frequent side effect of repellents in soldiers (Fai and Lee 1996). Some studies reported on the development of severe bullous irritant dermatitis from use of the repellent diethyl toluamide (Lamberg and Mubrennan 1969 Reuveni and Yaqupsky 1982 Amichai et al. 1994). 

Uses sunscreen agent used to protect against sunburn (UV radiation) used to prevent skin cancer, premature aging of the skin and various forms of photosensitivity diseases color preserver in paints, cosmetics, varnishes, hair dyes and soaps common UV adsorber in dental composite materials and other plastic materials, topical sunscreens, moisturizers, shampoos, hair-care products, lipsticks, lip balms, nail polish, etc. 

Skin cancer— The three major types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Exposure to the sun s ultraviolet (UV) rays appears to be the most important environmental factor in developing skin cancer. This makes skin cancer a largely preventable disease when sun protective practices and behaviors are consistently applied and utilized. 

The physiologic sequelae of biotin deficiency are almost unexplored. Severe skin lesions, especially seborrheic dermatitis and Leiner s disease (Erythroderma desquamativum or exfoliative dermatitis), were increased in young infants bom of mothers on a restricted diet low in eggs, livers, and other biotin-rich foods. After biotin administration the lesions healed. There are claims that excess biotin produces a fatty liver characterized by heightened cholesterol content. Choline has no effect in the prevention of biotin-fatty livers (G2, M2). In mice with transplanted tumors, both the tumors and the blood levels of biotin are below normal (R8). More recent studies established a protection with avidin, the biotin-binding fraction of egg white, against tumor formation (K4). More data along these lines are still needed for confirmation. 

Uses Thiram is a dimethyl dithiocarbamate compound and appears as a white to yellow crystalline powder with a characteristic odor. Thiram is used to prevent crop damage in the field and to protect harvested crops from deterioration in storage or transport. Thiram also is used as a seed protectant and to protect fruits, vegetables, ornamentals, and turf crops from a variety of fungal diseases. In addition, it is used as an animal repellent to protect fruit trees and ornamentals from damage by rabbits, rodents, and deer. Thiram is available as dust, flowable, wettable powder, water-dispersible granules, water suspension formulations, and in mixtures with other fungicides. Thiram has been used in the treatment of human scabies, as a sunscreen, and as a bactericide applied directly to the skin or incorporated into soap.17,50,52...
