Histopathological and clinical traps in lichen sclerosus: a case report.

Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate. We present the case of a 40-year-old female patient clinically diagnosed with systemic scleroderma and lichen sclerosus involving the genital mucosa. Physical examination in conjunction with laboratory findings (elevated antinuclear, anti-Scl-70, anti-SSA antibodies and immunogram) induced the supposition of the coexistence of lichen sclerosus and systemic scleroderma, fact confirmed by pathological examination. Systemic therapy with corticosteroids, immunosuppressive and phlebotropic drugs, peripheral vasodilators and other tropic adjuvants and topically potent topical corticosteroids was initiated. The course was favorable under therapy, the hardened skin slightly regaining elasticity, relief of itching and disappearance of lichen sclerosus lesions. Our case reaffirms the uncommon association of these two disorders. The importance of history, physical and laboratory examinations in making a diagnosis of certainty in emphasized.

Applications of cyclodextrins in medical textiles - review.

This paper presents data on the general properties and complexing ability of cyclodextrins and assessment methods (phase solubility, DSC tests and X-ray diffraction, FTIR spectra, analytical method). It focuses on the formation of drug deposits on the surface of a textile underlayer, using a cyclodextrin compound favoring the inclusion of a drug/active principle and its release onto the dermis of patients suffering from skin disorders, or for protection against insects. Moreover, it presents the kinetics, duration, diffusion flow and release media of the cyclodextrin drug for in vitro studies, as well as the release modeling of the active principle. The information focuses on therapies: antibacterial, anti-allergic, antifungal, chronic venous insufficiency, psoriasis and protection against insects. The pharmacodynamic agents/active ingredients used on cotton, woolen and synthetic textile fabrics are presented.

Cotton-made cellulose support for anti-allergic pajamas.

The cotton used to produce an interlock knitted fabric is alkaline boiled, bleached and after drying, it is grafted with monochlorotriazinyl-beta-cyclodextrin (MCT-ß-CD) as a support of an inclusion compound (IC) with natural anti-allergic active principles, in order to improve the curative properties and the comfort. Are used: extract of Viola tricolor Herb (VtH), solution of propolis (P) and of menthol (M), as well as the pharmacologic products: advantan (AD), hydrocortisone (HYD) and pimechrolimus (PI). The dimensions of the active compound molecules were established with software. The textile material grafted with MCT-ß-CD and with active principles absorbed in the cyclodextrin cavity is investigated by EDX. The anti-microbial activity of VtH, P and M was tested. Tactile determinations of softness were performed with human appraisers. By assembling the anti-allergic knitted fabric with untreated fabric, therapeutic pajamas were obtained. The manner to process and manufacture the pajamas for patients with contact and atopic (DA) dermatitis (DC) is presented.
