1. O que significa paraceratose no resultado de exame citopatológico de colo de útero?
Paraceratose é um processo anormal da maturação da das células epiteliais, onde ocorre a retenção de núcleos na camada córnea, caracterizando um processo incompleto de queratinização das células superficiais do epitélio. É a persistência dos núcleos dos cenatinócitos dentro do stratum corneum (camada cornificada) da pele. Paraceratose é n

2. Vegetable moisturizing raw material from “Caatinga” Brazilian biome: safety and efficacy evaluations of O/W cosmetic emulsions containing Kalanchoe brasiliensis extract
The purpose of this study was to evaluate the safety of Kalanchoe brasiliensis extract, followed by the development of an oil in water emulsion containing the K. brasiliensis leaves extract and evaluating its clinical moisturizing efficacy. The formulations containing sodium acrylates/ Beheneth-25 methacrylate Crosspolymer (and) hydrogenated polydecene (and)

3. Physical methods for topical skin drug delivery: concepts and applications
Topical drug delivery is an interesting approach to treat skin diseases and to avoid pain and low patient compliance in cases where a systemic delivery is required. However, the stratum corneum, which is the outermost skin layer, strongly protects the body from the entrance of substances, especially those hydrophilic. In this context, different physical meth

4. Active ingredients, mechanisms of action and efficacy tests of antipollution cosmetic and personal care products
Urban population around the globe is direct exposed to the pollution caused by several sources (vehicles, industries, smokes etc.) and primary pollutants are divided in particulate matter and toxic gases. Current researches in populous countries indicated that exposure to pollution could affect sebum composition, stratum corneum quality and signs of skin agi

5. The pH of the main Brazilian commercial moisturizers and liquid soaps: considerations on the repair of the skin barrier
Abstract: The pH of the skin is slightly acidic (4.6 to 5.8) which is important for appropriate antibacterial, antifungal, constitution of barrier function, as well as structuring and maturation of the stratum corneum. This study aimed to evaluate the pH of the main commercial moisturizers and liquid soaps in Brazil. Thus, pH of the products was quantified b

6. Metronidazole thermogel improves retention and decreases permeation through the skin
ABSTRACT Metronidazole (MTZ) is widely used as the standard antibiotic for the treatment of rosacea and, more recently, is being used off label in Brazilian hospitals for the treatment of wounds. Following oral administration, minimal amounts of active agent reaches the skin and side effects are strongly induced. Consequently, MTZ is currently being applied

7. White piedra, black piedra, tinea versicolor, and tinea nigra: contribution to the diagnosis of superficial mycosis
Abstract Superficial mycoses are fungal infections restricted to the stratum corneum and to the hair shafts, with no penetration in the epidermis; they are: white piedra, black piedra, tinea versicolor, and tinea nigra. This study presents images of mycological tests performed in the laboratory, as well as exams performed at the authors office, in order to i

8. Gelatin-based microspheres crosslinked with glutaraldehyde and rutin oriented to cosmetics
ABSTRACT Glutaraldehyde (GTA) has been extensively used as a gelatin crosslinking agent, however, new natural ones have been suggested as more biocompatible. Polyphenols are possible candidates and the flavonols, such as rutin (RUT), also exhibit potential synergism with sunscreens and antioxidant agents used in cosmetics. In this work, gelatin microspheres

9. Bacterial Cellulose Membranes as a Potential Drug Delivery System for Photodynamic Therapy of Skin Cancer
The development of drug delivery systems for photodynamic therapy (PDT) is increasingly demanded due to the hydrophobicity presented by most of photosensitizers molecules. Bacterial cellulose (BC), a highly pure cellulose produced by bacteria, possesses the essential features for applications in drug delivery systems, such as large surface area and excellent

10. Evaluation of skin absorption of drugs from topical and transdermal formulations
ABSTRACT The skin barrier function has been attributed to the stratum corneum and represents a major challenge in clinical practice pertaining to cutaneous administration of drugs. Despite this, a large number of bioactive compounds have been successfully administered via cutaneous administration because of advances in the design of topical and transdermal f

11. The acute effects of preoperative ozone theraphy on surgical wound healing
ABSTRACT PURPOSE: To investigate the effects of preoperative rectal ozone insufflation on surgical wound healing over the proinflammatory cytokines and histopathological changes. METHODS: Twenty one rabbits were divided into 3 groups. Sham, surgical wound, and ozone applied (6 sessions, every other day 70 µg/mL in 12 mL O2-O3 mixture rectally) surgical wo

12. Pitted keratolysis
Abstract Pitted keratolysis is a skin disorder that affects the stratum corneum of the plantar surface and is caused by Gram-positive bacteria. A 30-year-old male presented with small punched-out lesions on the plantar surface. A superficial shaving was carried out for scanning electron microscopy. Hypokeratosis was noted on the plantar skin and in the acros
