Evidence for the phagocytosis of intact oligolamellar liposomes by human keratinocytes in vitro and consecutive intracellular disintegration.

While there is evidence for the use of liposomes as drug carriers upon topical application to the skin, the underlying mechanisms are far from being clear. Therefore human keratinocytes grown in vitro were exposed to large oligolamellar liposomes. After attachment and invagination these particles can be found unchanged within the cytoplasm both inside and outside of lysosomes. If incorporated into lysosomes the structural lipids can be disintegrated and spread within the entire phagolysosome. Gold labeling adds further to the hypothesis of intact uptake of liposomes by the living cells of the human epidermis.

[Contact urticaria with transition to protein contact dermatitis in a cook with atopic diathesis].

Protein contact dermatitis is a rare disease within the group of occupational dermatoses. However, it is of some importance to people in food handling occupations. Skin symptoms usually manifest as immediate-type reactions (type-I-reaction according to Coombs and Gell), but changes to type IV-reactions are known. This applies especially to people with atopic eczema who have contact to fish proteins. This can be derived from a case presented here and a few similar observations described in the literature.

[Dermatomycoses as occupational diseases. The causative agents, sources of infection and the involved occupations].

Fungal diseases of the skin can be occupational dermatoses. This applies in particular to diseases due to microorganisms acquired from animals. A discussion of the relationship between occupation and disease, however, is not only pertinent in regards to dermatophytoses due to zoophilic fungi but also with those due to geophilic and--to a certain extent--even anthropophilic ones. The same is true of candidiasis. The present review deals with the various standpoints concerning the role of occupation in the development of cutaneous mycoses. In addition casuistic evidence for the various types disease, is compiled and discussed.

[Antiperspirants and deodorants--ingredients and evaluation].

Antitranspirants and deodorants gain more and more interest. Aluminium chlorohydrate and aluminium zirkonium tetrachlorohydrate glycine complex are the most frequently used active ingredients in commercial antitranspirants today. Aluminium chloride and propantheline bromide, the anticholinergic substance, are important alternatives although less common. Active ingredients of deodorants are mainly perfumes or bactericidal/bacteriostatic substances, such as triclosan. In addition, there are substances which are meant to bind offending smells (e.g. zinc ricinoleate) or to influence the skin surface pH (e.g. triethyl citrate). As in the cosmetics industry in general, both safety and efficacy of a product are major parameters in the experimental and clinical evaluation. Establishment of efficacy is based on olfactory tests in model situations as well as on the detection of associated effects (e.g. influence on cutaneous microflora).
