Dexpanthenol is a well-known moisturizer with barrier-improving properties and the oily phase of the water in oil preparation forms a lipophilic film on the skin surface that isolates the skin from irritants (feces and urine). Prolonged contact with irritants triggers a local inflammation cascade responsible for the cutaneous erythema. To further investigate the protective properties of skin barrier preparations, we took advantage of an ex vivo model of healthy human skin discs especially designed to evaluate protective and/or repairing effects of topical preparations recommended for baby’s buttocks through the measurement of interleukin-1 alpha release (a cytokine considered as the Primum movens of the skin inflammatory reaction), following the application of different irritants. Methods: Healthy human skin discs have been incubated in the absence (control) or in the presence of two irritants, i.e. a “urine like + urease” preparation and sodium dodecyl sulfate, and in the presence of three ointments, one containing dexpanthenol, but not the other two. At the end of the incubation period, interleukin-1 alpha (IL-1α) was quantified in the explants culture media. Results: “Urine like + urease” preparation (ULU) and sodium dodecyl sulfate (SDS) both increased IL-1α production of skin explants by 181.1% (p α release by 67.42% (p α release by 45.94% (p α production regardless of the irritant applied. Moreover, the effect of the dexpanthenol containing formula on the ULU-induced IL-1α release was significantly higher than the effect of the other formula; a difference of 19.6 % (p ®) provides good protection of baby’s buttocks against irritants. Its protective effect seems to be superior compared with other products, which did not contain this ingredient. Moreover, the results obtained in the present study suggest that dexpanthenol displays per se a real IL-1α production inhibitory effect. This work, however, consists of preliminary studies and additional investigations involving more formulas and end-points such as the quantification of other pro- or anti-inflammatory cytokines and/or resolvins for example, are needed to better understand the cutaneous protective effect of dexpanthenol.","PeriodicalId":15654,"journal":{"name":"Journal of Cosmetics, Dermatological Sciences and Applications","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84857469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: We aimed to investigate the differences and similarities between vitiligo and nevus depigmentosus in children based on the clinical course and characteristics. Materials and Methods: We conducted an examination of the disease type, treatment, progress, and differentiation of 85 cases of vitiligo and nevus depigmentosus that developed before 15 years of age among patients who visited the Osaka University Department of Dermatology with a chief complaint of white patches from January 2010 to March 2017. Results: The median age at the onset of symptoms of 79 patients with vitiligo was 4.5 years and while that of 6 patients with nevus depigmentosus was 0.8 years, indicating that the onset of nevus depigmentosus occurred earlier. While vitiligo often developed in the head and neck regions, with a tendency for depigmented spots in multiple regions, nevus depigmentosus did not show this tendency in these regions. Upon performing Wood’s lamp observation in 38 cases of vitiligo, 35 cases were found to be fluorescent chalky white and in 3 cases histologically diagnosed as vitiligo, no clear fluorescent color was observed. All 6 patients diagnosed with nevus depigmentosus exhibited a non-fluorescent off-white color under a Wood’s lamp. Conclusions: This study indicates that non-invasive observation using a Wood’s lamp is useful in the differential diagnosis of pediatric leukoderma, in addition to the subsequent clinical course, such as the presence or absence of lesional repigmentation and/or enlargement.","PeriodicalId":15654,"journal":{"name":"Journal of Cosmetics, Dermatological Sciences and Applications","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77406609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

About 70% - 80% of them suffer from these infections during their lifetime. These infections occur in two forms, gingivitis and periodontitis. Gingivitis is a reversible inflammation of the gingiva which can be cured. As with humans, the harmful bacteria can cause infections also in organs such as the heart, liver and kidneys. Besides veterinary treatment, also the owner’s everyday care is essential. Objective: The aim of the study was to develop and clinically test easy home care probiotic product for cats’ and dogs’ oral health. Methods: Nine cats and thirteen dogs were given a combination of selected bacteria Streptococcus thermophilus SP4, Lactobacillus plantarum 14D and Lactobacillus rhamnosus SP1 (Petguide powder) in powder form daily for four weeks on top of the dry feed. Microbiological samples were taken before and after the intervention from each dog and cat. The samples were analyzed with flow cytometric analysis using Porphyromonas gingivalis and Fusobacterium sp. as indicators for oral health. Results: The home care treatment with these specific, live probiotic bacteria was shown to prevent the growth of infectious bacteria within four weeks. Petguide probiotic powder reduced the relative abundance of infectious microbes significantly (p = 0.005) in cats and dogs. Conclusion: The results suggest that the probiotic product with three live strains of probiotic bacteria prevents the growth of infectious bacterial species that are known to cause infections in pets’ mouths. Therefore, this probiotic combination could be used to improve the oral health of pets and increase their quality of life.","PeriodicalId":15654,"journal":{"name":"Journal of Cosmetics, Dermatological Sciences and Applications","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88092442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In human cells submitted to oxidative stress the telomeres length decrease, the expression of progerin and the activity of mTOR are increased. At our knowledge, there is no published data on Cps correlated with ultraviolet radiation (UV) and blue light effects in human cells regarding telomeres’ length, progerin expression or mTOR1 complex activity. Objectives: In this study, we sought to assess 1) telomeres’ length in newborn human fibroblasts exposed to UV and blue light; 2) progerin production in mature human normal fibroblasts exposed to UV; 3) mTOR1 activation in adult human normal keratinocytes exposed to UV, analyzing the activity of a Cyanobacteria phycocyanin (Cp) in these in vitro models. Materials and Methods: Human skin fibroblasts or human normal keratinocytes were cultured—in the absence or in the presence of Cp and submitted to UVB + UVA and blue light irradiations. Telomeres’ length, progerin expression and mTOR1 activity were then assessed by molecular biology and immuno-enzymatic methods. Results: In cultured fibroblasts exposed to irradiations and treated by Cp, telomeres’ shortage and progerin expression were lower compared to irradiated untreated cells. In cultured keratinocytes treated by Cp and exposed to irradiations, the mTOR activity was lower compared to irradiated untreated cells. Conclusions: In these in vitro studies on human skin fibroblasts and on normal human keratinocytes, the cyanobacteria phycocyanin (Cp) showed a decrease of damages induced by UV and blue light expressed by telomeres preservation and downregulation of progerin expression and of mTOR activity, thus showing skin anti-aging and photo-protective potential.","PeriodicalId":15654,"journal":{"name":"Journal of Cosmetics, Dermatological Sciences and Applications","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81204161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretically speaking, the worst filler will have, at least, ᆠ score and the best will have a score of 34 points. Some scoring points do not exist in any filler, suggesting hints to improve all brands. Objectives: To build a Hyaluronic acid dermal filler scoring system that deals with what the injector can easily read, see or experience on their own without using sophisticated technologies or the need to understand or estimate the physics or the chemistry behind the filler. Using a scoring system that depends more on objective than subjective findings will be easy and unbiased to apply, more practical.
