RESUMEN
Contact dermatitis is a chronic inflammatory skin disorder with a highly variable prevalence worldwide. Smoking plays a crucial role in mediating inflammatory skin conditions such as contact dermatitis. The present study aimed to investigate the association between smoking status and contact dermatitis in the Saudi population. The patients in the present study were individuals older than 18 years who were diagnosed with contact dermatitis and received a patch test at the Department of Dermatology of King Saud University Medical City from March 2003 through February 2019. All patients were interviewed by phone to complete a specific pre-designed questionnaire to assess tobacco use or exposure history. The total number of enrolled patients in the study was 308 (91 males and 217 females), all with contact dermatitis. Data from the present study suggest that the prevalence of allergic contact dermatitis in smokers may be less than that in non-smokers. Moreover, the prevalence of irritant contact dermatitis in smokers is more significant than in non-smokers. Finally, left-hand contact dermatitis is significantly associated with smoking. Therefore, there is a strong association between smoking and irritant contact dermatitis, especially in the Saudi population, regarding the left hand. Further epidemiologic studies are needed to further explore the role of smoking in the occurrence of contact dermatitis and to explore the possible mechanisms.
RESUMEN
Objective: This study was aimed at evaluating the knowledge and behavior toward venous thromboembolism (VTE) prophylaxis among medical interns. Methods: This is a questionnaire-based cross-sectional observational cohort study of medical interns that used a validated questionnaire. The questionnaire comprised of items that assessed behavior, knowledge, and self-assessment of VTE risk factors, diagnosis, and prophylaxis. The study was conducted in Riyadh, Saudi Arabia, from October 2020 till September 2021. Results: The respondents were 246 medical interns. The overall rate of correct responses to behavior items was 41.82%. The overall rate of correct responses to knowledge items was 47.35%. A total of 61.8% responded negatively to the use of VTE risk assessment guidelines (p < 0.0001). For the self-assessment of knowledge of VTE, more than 70% believed they did not have appropriate knowledge, were not prepared to establish the risk of VTE, and were not prepared to provide adequate prophylaxis for VTE (p < 0.0001). A high proportion of medical interns (83.3%, p < 0.0001) believed they needed further training on this topic. Conclusion: Participants in this study showed poor knowledge and negative behavior regarding the assessment of risk factors, diagnosis, and prophylaxis of VTE. The majority of participants reported they needed training on this topic. These findings underscore the need for educational programs during undergraduate training and orientation of medical interns for VTE risk assessment, diagnosis, and prophylaxis at the beginning of their internship.
