This study analyzes the response to 448-kHz CRET treatment in 20 patients with Female Pattern Hair Loss (FPHL) and in woman’s Dermal Papilla Cells (DPC).\u0000\u0000Methods: Patients received ten 20-minute CRET sessions over an 8-week interval. Three months after the last session, the effects of the treatment were trichoscopically analysed. DPC were CRET stimulated intermittently for 12, 24 or 48 h and the effects on cell proliferation and expression of several proteins involved in cell proliferation were analysed.\u0000\u0000Results: Trichoscopic data revealed generalized, statistically significant hair redensification (10 – 15 % over pre-treatment values) in all the treated scalp areas. In-vitro electrostimulation significantly increased DPC proliferation and expression of the proteins involved in cell proliferation. Since dysregulation of DPC proliferation is the main factor underlying abnormal hair loss, it is likely that electrically-induced DPC proliferation is involved in the redensifying effects obtained in the trichological study.\u0000\u0000Conclusion: The results of the trichological study in FPHL patients and those of the experimental study in woman’s DPC are consistent with each other and suggest that 448-kHz CRET could be effective both for hair redensification and hair loss prevention.","PeriodicalId":15448,"journal":{"name":"Journal of clinical & experimental dermatology research","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78803068","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}

It is postulated that the SS-caused UV radiation overwhelms the skin cell’s capacity to repair/remove DNA lesions (about 70,000 non-cumulative lesions per day) and any of these un-repaired/un-removed lesions can eventually become a pre-cancerous tumor or cancer after overcoming numerous barriers of body’s repair/defense mechanisms. The above rationale for cancer etiology seems consistent with the classical wound-to-tumor doctrine. Infection with Human Papillomavirus will reduce the threshold for non-cumulative DNA lesions thereby facilitating cancer initiation. The proposed SS theory may be generally applicable to people with different races, skin types, hair colors and sunlight exposures. The proposed non-cumulative UV damage concept is supported by published data showing parallel first-order aging kinetics of human skin being exposed and un-exposed to sunlight in ordinary people. Solar UVA only plays a minor or insignificant role in skin cancer and premature aging. Prevalence of SS is reviewed. Controversies on skin cancer risks for indoor and outdoor workers such as airplane pilots and crew, health workers, gardeners and truck drivers are discussed. Potential shortcomings of a common practice of using highly unphysiological UV, UVA or UVB doses in animal, cell culture or human skin studies are discussed. Demonstration resembling the reversibility of intrinsic skin aging using a plant deprived of and then replenished with water is presented. It is hoped that this apparently provocative work may stimulate further discussions in the literature.","PeriodicalId":15448,"journal":{"name":"Journal of clinical & experimental dermatology research","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75242885","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}

Interventions to mitigate these changes are of interest. Aim: To examine the safety and efficacy of LustrivaTM (a novel source of biotin and silicon) at a high or lower dose compared to placebo for impacts on hair and skin. Materials and Methods: In a randomized, double-blind study, 90 healthy female subjects with self-reported thinning hair who met Savin/Ludwig Scale criteria I-2 to II-1 by physician evaluation were randomized to one of three groups for 12 weeks (n=30/group): LustrivaTM High-Dose (LHD), LustrivaTM Low-Dose (LLD) or Placebo (PL). Hair quality and thickness measured by the TrichoScan HD testing system and skin parameters (facial wrinkles, fine lines, skin texture, skin color evenness, skin elasticity) measured by the Antera 3DTM System and the CutometerTM Dual MPA 580 system. Results: There was a significant increase in hair thickness measured by change in % vellus hair and % terminal hair and in the ratio of % vellus to terminal hair in LHD compared to PL at Week 3, maintained throughout the study (p=0.029). LHD had a significant decrease in facial wrinkles (12 Weeks) measured by a change in maximal wrinkle depth vs. PL (p=0.031). After 12 weeks compared to baseline LHD significantly improved facial wrinkle Maximum Depth, Indentation Index and Score, facial fine lines Indentation Index and Score, and facial texture Maximum Height, Roughness and Score (p<0.05), no change in PL. There were no changes for skin elasticity between groups. For some hair and skin parameters, LLD showed improvements less than LHD but that approached significance (p<0.1). All groups improved in subjective nail endpoints vs. baseline with no significant differences between groups. No adverse events reported. Conclusion: LHD significantly increased hair thickness and reduced facial wrinkle depth compared to placebo and performed better than the LLD in most parameters. Future studies are warranted.","PeriodicalId":15448,"journal":{"name":"Journal of clinical & experimental dermatology research","volume":"15 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84907025","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}

Infestation occurs when the \"itchy\" mite, S. scabiei, penetrates the skin and eats the epidermis of the host. This infestation is a major problem that occurs in many indigenous communities and less developed countries in both sexes. Information about the prevalence of this disease in Iran is low. Thus this study aimed to determine the future of infestation in Isfahan. Methods: 283 patients with clinical futures of scabies, who were examined by a dermatologist, from different medical centers in Isfahan, were assayed. Sampling was performed directly from the epidermis with mineral oil on the newest nodules by a scalpel blade. The specimens were examined by microscope with low and high magnification to confirm the infestation and then the results were analyzed by SPSS software v.23. Results: With the microscopic examination, 86 (72.3%) out of 119 males and 100 (64.1%) out of 156 females with clinical futures of scabies indeed had the disease yet there was no significant statistical difference in the infestation rate with the sexes (p=0.096). Among the occupations, the highest level of infestation was observed in Artisan, 10 (71.4%) out of 14. No significant difference was observed among different occupations and the infestation rate (p=0.97). Conclusion: The frequency of the disease in Isfahan is high, but for a more accurate assessment of the disease, more studies with the same methodology should be done to take appropriate health measures for this disease.","PeriodicalId":15448,"journal":{"name":"Journal of clinical & experimental dermatology research","volume":"59 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85733500","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}

It is found, for example, that experiencing 1-5 and ≥ 6 SSs increased one’s risk for melanoma in men by 12.7-fold and 22fold, respectively. Since use of sunscreen during intense intermittent sun exposure can cause unintended SS, a false security phenomenon, sunscreen can be postulated as a potential major risk factor for causing skin cancers. Because chronic exposure to non-burning sunlight is protective against melanoma and can enhance immunity, this protective effect may also likely occur with less serious BCC and SCC. Therefore, regular exposure to non-burning sunlight may serve as a new strategy for skin cancer prevention and general health promotion. It is theorized that in addition to immunity enhancement, regular exposure to non-burning sunlight can result in skin tanning that will protect against sunburn and thereby protect against skin cancer. The role of erythema, a mild sunburn, in cancer incidences may be relatively limited. Since skin aging in ordinary people may be predominantly caused by the intrinsic factor, and SS is predominantly caused by intense ultraviolet (UV) B rays, the need of using broadspectrum sunscreens or organic sunscreen ingredients for protection against UVA may need to be re-considered.","PeriodicalId":15448,"journal":{"name":"Journal of clinical & experimental dermatology research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90472375","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}
