OBJECTIVE To observe the effects of low intensity laser therapy in inflammation, wound healing and epithelialization of island skin grafts. METHODS Twenty rats were subjected to this grafting technique and divided subsequently into two equal groups, one treated with laser and the other control. RESULTS there was less inflammation, faster healing, epithelialization and keratinization in the ...

ABSTRACT Dandruff is often seen in the primary care setting as well as in the dermatology field. In this article, we review the most commonly prescribed topical shampoos for treating dandruff and compare their efficacy in eradicating the symptoms of dryness and flaking of the scalp, along with providing relief of associated pruritus. Examples of such agents include keratolytics, regulators of k...

Porokeratosis, a keratinization and fibroblast cutaneous disorder, is a progressive disease with limited treatment options. We describe a case of linear porokeratosis that responded favorably to a series of 585 nm pulsed dye laser treatments. In addition to its vascular specificity, the pulsed dye laser presumably produces a direct effect on collagen, as well as an indirect effect on histamine ...

In both the initial biopsy and the complete excision of the lesion, specimens were obtained for hematoxylin-eosin staining. Both specimens showed a well-defined, unencapsulated cystic tumor formed by several different-sized lobules composed of an external layer of basaloid cells and several layers of eosinophilic spindle cells with abrupt keratinization (Fig. 2). No atypia or mitotic figures we...

Porokeratoses are a group of different entities that belong to the skin keratinization disorders. From the histological point of view the main and common characteristic of these disorders is the presence of compact parakeratotic columns known as cornoid lamellae. All varieties should be carefully treated and followed-up because of the risk of developing malignant epithelial tumors. We report th...

The biosynthesis of corneal epithelial proteins and glycoconjugates and their response to vitamin A were measured in vitamin A-deficient and normal rats. The synthesis of specific high-molecular-weight epithelial glycoconjugates was directly related to the levels of vitamin A administered. Protein synthesis, however, remained unaltered. Since vitamin A is known to reverse the keratinization pro...
