Introduction
The use of sunscreen is an important preventive measure against skin cancer and treatment for other skin conditions. There is evidence pointing to lack awareness and misconceptions regarding use of Sunscreen. This is especially evident in populations with skin of color (POC).
Methods
This is a cross‐sectional study of 2000 individuals. A structured questionnaire was designed to collect data on general knowledge and use of sunscreen as well as reasons for stopping use of sunscreen.
Results
The results of this study indicate a clear deficiency in the use and knowledge about sunscreen among Jordanians. Females are using sunscreen more than males. However, the use of sunscreen is inadequate in many aspects including timing of application, frequency of use, and amount used among other things. There is an obvious lack of knowledge about sunscreen as shown by lack of awareness about benefits of use in various times of the year, use in children, use for all skin types, and several misconceptions among other knowledge gaps. Main reasons for stopping sunscreen include side effects, cost, and being not suitable for skin. Awareness about sunscreen can be improved by proper counseling by healthcare professionals and utilization of various media platforms.
Conclusions
The use of sunscreen is inadequate in this population of color (POC). Lack of proper counseling, failure to read use instructions can contibute to inadequate use of sunscreen. Risks and benefits of sunscreen should be explained by medical professionals. The media should be more utilized to disseminate such knowledge.
Background: Pruritus is the most common symptom in patients with skin disease. Psoriasis and atopic dermatitis are clinically distinct inflammatory diseases. Interleukins are cytokines which play key roles in inflammatory signaling pathways. Materials and Methods: Cross-sectional study was conducted among patients with psoriasis and atopic dermatitis: 59 psoriatic patients, 56 AD patients, and 49 matched healthy controls. Interleukins 4, 13, 31, 33 serum levels were assayed by ELISA and results were compared using SPSS. Itch severity and disease severity were measured and correlation with interleukin levels was determined using SPSS. Results: The serum levels of IL-4,-13,-31,-33 were elevated in atopic dermatitis patients compared to controls. Itch and disease severity were not correlated with elevated serum levels of these interleukins. In psoriasis, the levels of IL-4 and-31 were elevated compared to controls, whereas the levels of IL-13 and-33 were lower than controls. The levels of measured interleukins in psoriasis did not correlate with itch and disease severity. Conclusion: IL-31 is the key mediator for pruritus in both AD and Ps patients. IL-4/31 axis and IL-33/13 axis play distinct roles in the pathogenesis of Atopic dermatitis and Psoriasis. Interleukin serum levels were not correlated with itch and disease severity in both conditions.
Background: The human papillomaviruses (HPV) are a group of viruses that, depending on the strain, can cause cancer or the formation of benign growths known as warts. Scarce information exists with regard to the genetic nature of non-genital cutaneous warts induced by the human papillomavirus (HPV). Methods: The main purpose of this study is to investigate the differences between the gene expression profiles of common warts and healthy skin in HPV-positive individuals by RNA sequencing on the Illumina HiSeq 2500. After obtaining shave biopsies of common warts and healthy skin from twelve Arab males, we were able to analyze the transcriptomes of 24 paired cases and controls. Results: Common warts were found to possess a highly significant and unique molecular signature. Many of the most up-regulated (KRT16, EPGN, and ABCG4) and down-regulated genes (C15orf59, CYB561A3, and FCGRT) in warts were the subject of little investigation in the published literature. Moreover, the top 500 differentially expressed genes were found to be associated with immune and autoimmune pathways, such as the neutrophil degranulation, toll-like receptor 7/8 (TLR 7/8) cascade, toll-like receptor 9 (TLR9) cascade, and toll-like receptor 10 (TLR10) pathways, among others. Conclusions: Our findings are particularly important because they serve as the most comprehensive to date with regard to the modulation of human skin gene expression by HPV infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
