Objective: The aim of this study was to detect cytological changes and Ki-67 protein expression in oral mucosa among water pipe users. Methodology: A case control study was study was carried out in Saudi Arabia from January to October 2022, two cytological oral smear samples were taken from 500 volunteers 300 were water pipe users (case) and 200 were normal individuals (control) and were stained using the Papanicolaou staining procedure and immunocytochemical method to show the expression of Ki-67. Result: Inflammation, infection, atypia and keratinization were interpreted from Papanicolaou stains. The prevalence of cytological inflammation was higher among water pipe smokers (77/300, 25.6%) than among non water pipe users (12/200, 6%). Reverse cytological infection and atypical were higher in water pipe smokers than in control, 9% versus 4.5% and 4.3% versus 0.5%, respectively, while keratinization was only identified in water pipe users (3.6%) versus control groups. The Ki-67 protein is expressed at a higher level in water pipe users compared to non users. Conclusion: The study results concluded that water pipe users had more atypical cells and more KI-67 protein expression in the oral mucosa as compared to their non water pipe users' counter parts.
Introduction: Stroke is a devastating neurological condition. No recent studies conducted in the Western Region of Saudi Arabia regarding stroke. Therefore, our aim is to assess the awareness towards early manifestations of acute stroke among adults in the Western Region and to identify a relationship between the level of awareness and different sociodemographic data. Method: A cross-sectional study will be conducted by using validated questionnaire among general public from July 2022 to November 2022. The data will be collected through social media. Result: A total of 352 participants completed the questionnaire. Almost (67%) were female, majority from Medina Province (76.1%), about 92.0% have heard about the terminology Stroke. Good awareness was leaning towards younger age groups. Furthermore, educational level has a significant difference on the level of awareness on stroke symptoms manifestations at p-value = 0.001, others demographic factors are not correlate with the level of awareness regarding stroke. Conclusion:The percentage of participants with good awareness was almost the same as that of those with poor awareness, therefore, this knowledge gap must be fixed to improved prevention.
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.
