Introduction Multiple sclerosis (MS) is an autoimmune disease that can be disabling to patients. Smoking has been proposed to be a risk factor for MS and to increase the risk of progression of the disease and its severity. However, it is still not clear how smoking affects people with MS (PwMS) regarding disease phenotype, symptoms, relapses, course, and disability. The aim of this study is to investigate the effect of smoking on PwMS in Saudi Arabia. Methods This is an online questionnaire-based cross-sectional study. PwMS were randomly contacted through different MS societies and associations to participate in the study. The questionnaire inquired about demographics, MS phenotype and severity, and smoking status of the participants. Data were collected between May 30, 2021, and July 5, 2021. Results Four hundred twenty-nine PwMS participated in the study. The mean age was 33.7, with a mean disease duration of 8.1 years. About 61.1% of the participants were female. About 62.2% did not know the specific MS phenotype they have. About 35.7% were current or previous smokers, with a mean smoking duration of 13.9 years. Smoking was significantly associated with the presence of multiple MS symptoms (p-value = 0.009) and their number (p-value = 0.050). In addition, there was a significant positive correlation between pack-years smoking and the number of MS symptoms with a Pearson's r value of 0.165 (p-value = 0.001). No significant associations were found between smoking and recent relapses and disease progression, disability in terms of walking, needing a cane, or needing a wheelchair. Conclusion Smoking was shown to have a significant effect on the number of symptoms experienced by PwMS. Higher pack-years of smoking correlates positively and significantly with a higher number of MS symptoms. Further studies to examine these relations are hence warranted.

Background: Self medication is the use of pharmacological drugs without a prescription. The prevalence among medical students was found to be higher reaching 70.1%.

IntroductionTesticular torsion (TT) is the most common urological emergency in children that requires immediate intervention. The prognosis of testicular torsion depends on the patient's time of presentation to the emergency department (ED), as well as on the time at which the diagnosis is established and treatment is initiated. Raising public awareness of testicular torsion, particularly among parents, plays a crucial role in preventing delay in presentation and reducing the frequency of orchiectomy. To this end, the study is designed to assess the level of awareness and knowledge of testicular torsion, as well as the response of parents to the scrotal pain of their children. MethodsA descriptive cross-sectional study was conducted among parents in the western region of Saudi Arabia. Data was collected between the 23rd of November and the 22nd of December 2022. A simple random sampling technique was implemented. The data was collected and analyzed using SPSS software (IBM Corp., Armonk, NY). ResultsA total of 394 parents participated in this study. It showed that 13.5% of parents reported having a child with a previous experience of pain in the scrotum. Of them, only 25.4% previously heard about torsion of the testicles. Only 68.8% and 76.6% correctly reported that if the child complains of pain in the scrotum during working hours or over the weekend, they will drive him to the hospital immediately. Good knowledge about TT was significantly higher among children's fathers compared to mothers (66.7% vs. 33.3%) (p≤0.05). ConclusionTesticular torsion (TT) represents significant morbidity among male patients and early identification is crucial to avoid the need for orchiectomy and all its prominent physical and psychological consequences. To improve children's well-being, we need to raise parents' awareness of TT and the potential future implications of this critical condition as it is not widely known in our community. Further studies evaluating the knowledge regarding testicular torsion among preadolescent and adolescent boys are warranted.
